    Gout is a disorder of purine metabolism described by the deposition of monosodium urate crystals with rare involvement in the head and neck. This is the first laryngeal gout case reported in Sabah, Malaysia. A 50-year-old gentleman with a long history of gouty arthritis presented with acute painless anterior neck swelling for two weeks. An ultrasound of the neck was done, which showed a midline neck mass with intralesional calcification of the cartilaginous component with suspicious erosion of the thyroid cartilage, which was suggestive of thyroid chondroma. However, a computed tomography (CT) scan of the neck showed the fluid collection in the subperichondrium of anterior thyroid cartilage with amorphous calcification, which raised suspicion of infected laryngeal gout. Based on histology and intraoperative findings, laryngeal gout was diagnosed as noted multiple tophy crystals. Microscopic examination confirmed birefringent crystalline deposits. The pathophysiology and management of this rare clinical entity are discussed. We reported this case due to its rarity as well as to increase awareness of laryngeal gout.

    G protein-coupled receptor 139 (GPR139), a highly conserved orphan receptor, is predominantly expressed in the habenula of vertebrate species. Habenula is an ancient epithalamic structure, which is critical to comprehending adaptive behaviors in vertebrates. We have previously demonstrated the role of GPR139 agonists in fear-associated decision-making processes in zebrafish. However, how GPR139 signaling in the habenula modulates such adaptive behavioral responses remains unsolved. Fish centrally administered with a synthetic antagonist for human GPR139 (NCRW0005-F05) exhibited significant suppression of odorant cue (alarm substance, AS)-induced fear learning in the conditioned place avoidance paradigm. On the other hand, co-treatment with a GPR139 antagonist and a synthetic agonist for human GPR139 (JNJ-63533054) interrupted the fear conditioning process by significantly reducing locomotion during post-conditioning. Calcium imaging of acute brain slices showed a significant increase in peak amplitude of calcium transients in the habenula upon bath application of either a GPR139 antagonist or agonist. Furthermore, KCl-evoked calcium transients were reduced by the GPR139 antagonist and co-treatment of the GPR139 antagonist-agonist. These results suggest that the GPR139 antagonist did not block the inhibitory action of the GPR139 agonist in the decision-making process during the fear-retrieval phase; however, solitarily, it functions in governing the fear consolidation process via activation of the ventral habenula neurons in zebrafish.

    Background and objectives A modified aligner appliance with nickel-titanium springs (MAA) is a relatively new appliance that has not received extensive attention in orthodontics. This study evaluated the patient-reported outcomes when orthodontic treatment was provided using a modified aligner appliance to treat mild lower incisor crowding. Materials and methods This prospective cohort study consisted of 42 patients (11 males and 31 females; mean age 21.69 ± 2.56 years) with mild crowding. Twenty-one patients were treated using a modified aligner with nickel-titanium springs, while the remaining patients were treated with a conventional fixed orthodontic appliance (FA). Patient responses regarding pain, discomfort, and difficulty in chewing, swallowing, and speaking were recorded using a visual analog scale (VAS) at six assessment times: 24 hours (T1), two days (T2), three days (T3), two weeks (T4), one month (T5), and two months (T6) after appliance application. Results The mean perceived pain and discomfort levels were generally lower in the traditional fixed appliance (FA) group than the modified aligner appliance with nickel-titanium springs group at most assessment times. However, no statistically significant differences were found between the two groups. Chewing difficulty levels were similar between the two groups with no substantial differences. Swallowing and speech difficulty were significantly higher in the MAA group compared to the FA group during the first two days of treatment (P < 0.008). Conclusions Patients using both types of orthodontic appliances experienced temporary discomfort, including pain and difficulty chewing. While the modified aligners appliance with nickel-titanium springs caused additional challenges with swallowing and speaking, these issues were resolved over time, allowing patients to adjust to the treatment.

    One of the main challenges in breast cancer management is health system literacy to provide optimal and timely diagnosis and treatments within complex and multidisciplinary health system environments. Digitalised patient navigation programs have been developed and found to be helpful in high- and low-resource settings, but gaps remain in finding cost-effective navigation in the public sector in Malaysia, where resources are scarce and unstable. Hence, we set out to develop a virtual patient navigation application for breast cancer patients to enhance knowledge about cancer diagnosis and treatments and provide a tracking mechanism to ensure quality care. This paper identifies the requirement for in-hospital patients' navigational needs for cancer diagnosis, the cancer diagnosis and treatment process's components and pathways, developing the app and usability study on the usefulness of a cancer navigation mobile application in navigating cancer care at the University of Malaya Medical Centre (UMMC). Key features found when designing the in-hospital application are managing the medical appointments, finding the location of each medical department, and providing information to breast cancer patients, healthcare managers and providers to ensure a coordinated care pathway. In future work, we plan to implement the JURNI in-hospital patient navigation and perform usability studies involving the actual patients, physicians and administrators. We are also working towards enhancing data security, adding other local languages and artificial intelligence capabilities to improve the patient's journey.

    PURPOSE: To correlate fluorescein dye disappearance test (FDDT) grades and endoscopic dye transit times (EDTT) in patients with patent osteotomies after nasolacrimal duct obstruction surgery (NLDO).

    DESIGN: Cross-sectional study.

    METHODS: All adult patients with patent osteotomies post-external dacryocystorhinostomy (Ex-DCR) or post-endoscopic dacryocystorhinostomy (EDCR) for NLDO were included in this cross-sectional investigation. Patients with dry eye and endoscopically unidentified osteotomy sites were excluded from the study. The FDDT grade, EDTT and lacrimal symptom questionnaire (Lac-Q) scores were documented for all patients.

    RESULTS: This study included 39 patients. Nineteen had undergone EDCR, twenty Ex-DCR. The FDDT grade and EDTT were positively correlated (r=0.32, P=0.045). The mean Lac-Q score was not correlated with FDDT grade (r=-0.01, P=0.951) or EDTT (r=0.07, P=0.669). There were no significant differences in the FDDT grade, EDTT, Lac-Q score or ostial characteristics between Ex-DCR and EDCR.

    CONCLUSION: FDDT grading correlates with EDTT, suggesting that these tests may be used interchangeably based on the clinician's ease of access and instrumentation. There was no correlation between the symptoms of lacrimal outflow obstruction with objective evidence of drainage.

    BACKGROUND: Constipation is a common complication and an unpleasant experience during pregnancy. Due to hormonal factors, intestinal movements decrease during this time, causing the digestive system to malfunction. This study aims to explore the worldwide prevalence of constipation during pregnancy to prevent and minimize its complications.

    METHOD: Researchers conducted a meta-analysis of published data on the prevalence of constipation in pregnancy. The articles, which covered the period 1966 to 2024, were collected by searching Embase, PubMed, Scopus, Science Direct, Wos, and the Google Scholar search engine. The initial search was conducted on July 21, 2024, and the final update was made on August 10, 2024.

    RESULTS: Thirteen studies were identified to determine the prevalence of constipation during pregnancy. The results show that the global prevalence of constipation throughout pregnancy is 32.4%, with the first trimester at 21.1%, the second trimester at 34%, and the third trimester at 30.3%.

    CONCLUSION: According to a study, constipation is most common during the second trimester of pregnancy and the least common during the first trimester. Further research on the causes of constipation and prevention methods can help decrease its prevalence during pregnancy. Therefore, it is important to provide educational interventions on nutrition and encourage moderate physical activity during pregnancy to reduce the occurrence of constipation.

    The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has profoundly impacted global healthcare systems and spurred extensive research efforts over the past three years. One critical aspect of the disease is the intricate interplay between the virus and the host immune response, particularly the role of inflammatory gene expression in severe COVID-19. While numerous previous studies have explored the role of genetic polymorphisms in COVID-19, research specifically focusing on inflammatory genes and their associations with disease severity remains limited. This review explores the relationship between severe COVID-19 outcomes and genetic polymorphisms within key inflammatory genes. By investigating the impact of genetic variations on immune responses, which include cytokine production and downstream signalling pathways, we aim to provide a comprehensive overview of how genetic polymorphisms contribute to the variability in disease presentation. Through an in-depth analysis of existing literature, we shed light on potential therapeutic targets and personalized approaches that may enhance our understanding of disease pathogenesis and treatment strategies.

    BACKGROUND: Food insecurity is an important aspect of human suffering during wartime. Besides its ferocity, the Gaza conflict of 2023-2024 has been marked by severe food and medication shortages that exacerbated the human toll and worsened the suffering of the population.

    METHODS: A cross-sectional, mixed methods study that in April 2024 collected quantitative and qualitative data to assess food insecurity and malnutrition among residents of the Northern part of the Gaza Strip during the first seven months of the war. Quantitative data assessed weight loss among participants as a marker of starvation. Qualitative interviews evaluated food availability, food variability, and changing eating habits. Demographics were represented as counts and percentages. Weight was reported as mean ± SD. The Spearman Correlation Coefficient evaluated potential correlations of weight loss with sex, place of residence, and age. Statistical significance was set at a p-value less than 0.05.

    RESULTS: 497 participants were recruited, including 330 males (66.4%) and 167 females (33.6%). The age range was (13-83 years). The mean baseline weight was 84.94 kg ± 20.06, with a weight range (35-180 kg). In April 2024, the mean weight had dropped to 66.22 kg ± 14.34, representing an average decline of 18.72 kg (new weight range 28-142 kg). Age was associated with a weak positive correlation with weight loss (r = .204, p = .000). Qualitative interviews with 95 breadwinners or homemakers revealed a high prevalence of hunger and severe shortages in food quantity, quality, and variability. Physical and financial barriers significantly impacted food sourcing. Also, due to food shortages, most participants reported high consumption of edible wild plants and unconventional types of flour such as corn flour or grounded animal feed.

    CONCLUSIONS: The study demonstrated high levels of weight loss and marked food insecurity in the Northern Gaza Strip during the conflict. The quantitative and qualitative food shortages outlined in this study present a risk for a host of potentially serious and irreversible future complications.

    BACKGROUND: The manufacturing sector in Malaysia has been severely impacted by the COVID-19 pandemic. This is further exacerbated by Long COVID-19 symptoms among the manufacturing workers, which are proven to influence work performance and quality of life. Of note, there is currently a lack of knowledge regarding the burden of Long COVID-19 in the Malaysian manufacturing sector. As such, our study aims to investigate the prevalence and risk factors of Long COVID-19 symptoms among the manufacturing workers, and subsequently assess the prevalence and risk factors of adverse work outcomes among the workers with Long Covid-19 symptoms.

    METHODS: This is an exploratory mixed-methods study. In phase 1 (qualitative phase), three groups of participants (i.e., clinicians, employers, and workers) will be invited to participate to focus group discussions (FGDs) until thematic saturation. The aim of the FGDs is to explore the understanding, experience, and potential risk factors of Long Covid-19 among manufacturing workers. Findings from the FGDs will be analysed thematically. Themes generated from the FGDs will be used to generate items in a new questionnaire. The newly developed questionnaire will be validated using a fuzzy Delphi study, which will also be conducted among clinicians, employers, and workers. Phase 2 is a cross-sectional study that will be conducted among manufacturing workers across all states in Malaysia to identify the prevalence and risk factors of Long COVID-19, as well as the prevalence and risk factors of adverse work outcomes among workers with Long COVID-19. A multistage cluster sampling will be used to collect data from 4500 manufacturing workers in Malaysia. Logistic regression will be performed to determine the association between risk factors with both Long COVID-19 and adverse work outcomes.

    CONCLUSION: Once the prevalence and risk factors of Long COVID and its associated adverse work outcome are identified, timely support and effective interventions could be provided to manufacturing workers to maintain their health and productivity.

    ETHICAL CONSIDERATIONS: Ethical approval has been granted by the Research Ethics Committee of the National University of Malaysia (JEP-2023-607) and the Medical Research and Ethics Committee (MREC) Malaysia (NMRR ID-23-03310-H3E).

    Hydrogel coatings impart superior surface properties to materials, but their application on large and complicated substrates is hindered by two challenges: limited wetting conditions and intricate curing processes. To overcome the challenges, lyophilized adhesive hydrogel powders (LAHPs) are developed, which consist of poly(acrylic acid-co-3-(trimethoxysilyl)propyl methacrylate) crosslinked with chitosan. These powders are electrostatic sprayed onto substrates to address wetting issues and rehydrated to form bulk hydrogel coatings to circumvent curing challenges. This approach enables the application of hydrogel coatings with a smooth surface and adjustable thickness on various materials, irrespective of category, geometry, or size. The coatings exhibit remarkable mechanical properties (strength of 2.62 MPa, elastic modulus of 6.84 MPa, and stretchability exceeding 3 folds) and robust adhesion (adhesion energy ≈900 J m-2) through a three-step bonding process involving electrostatic attraction, hydrogen bonding, and covalent bonding. Notably, these coatings confer multiple functional attributes to the substrate, including lubricity, hydrophilicity, nucleation inhibition, and pH-responsive actuation. Moreover, incorporating LAHPs with functional agents or rehydrating with functional solutions opens possibilities for diverse functional hydrogel coatings, such as thermal responsiveness and NH3 indication. Leveraging the virtues of simplicity, flexibility, convenience, and broad applicability, this strategy presents an enticing pathway for the widespread applications of hydrogel coatings.

    Mpox, formerly known as monkeypox, has re-emerged as a significant global health concern, particularly during the widespread outbreak of 2022. As an orthopoxvirus related to the eradicated smallpox virus, mpox has been primarily managed with smallpox vaccines and treatments, including the antiviral agent Tecovirimat. This systematic review aims to evaluate the effectiveness and safety of Tecovirimat in treating mpox, focusing on its use during the 2022 outbreak, especially among high-risk populations, including men who have sex with men and people living with HIV. We conducted a comprehensive search across databases, such as Embase, PubMed, and Web of Science, up to August 30, 2024. The selection involved a two-stage review process utilizing the Nested Knowledge platform, which helped streamline the screening and data extraction. We included studies that focused on the clinical efficacy and safety of Tecovirimat in human patients with confirmed mpox infections. Our analysis mainly synthesized data narratively due to the heterogeneity of study designs and outcomes. Fifteen studies met the inclusion criteria, providing data on 1031 mpox cases. The preliminary analysis of the PALM 007 RCT indicated that tecovirimat did not significantly outperform placebo in lesion resolution for all patients. Lesions healed faster than expected, regardless of tecovirimat or placebo treatment. A lower mortality rate of 1.7% among those enrolled in the PALM 007 RCT was observed, compared to the general mpox mortality rate of 3.6% or higher in the DRC. Observational studies revealed that early administration of Tecovirimat, especially within the first week of symptom onset, significantly improves symptom resolution, reduces the severity of the disease, and decreases the likelihood of hospitalization and complications in observational studies. However, the impact on viral clearance was inconsistent, and some studies suggested limited efficacy in severely immunocompromised patients. Regarding safety, Tecovirimat was generally well-tolerated as indicated by the RCT; however, mild adverse effects such as fatigue, headache, and nausea were commonly reported among observational studies. Serious adverse events were rare but included elevated liver enzymes and psychiatric symptoms, particularly in patients with pre-existing conditions. Tecovirimat demonstrates some potential benefits in treating mpox, particularly when administered early. The PALM 007 RCT failed to meet the efficacy point. Tecovirimat is generally well-tolerated with a favorable safety profile, although monitoring is advisable for those with existing liver or renal conditions. Despite promising results, further large-scale randomized controlled trials are needed to fully ascertain the drug's effectiveness across diverse populations and to explore its impact on viral clearance and transmission dynamics.

    Soil conditions of croplands are a frequent topic of scientific research. In contrast, less is known about large-scale commercial plantations of perennial crops such as oil palm. Oil palm is a globally important tropical commodity crop which contributes to both food and energy security due to its exceptional productivity. However, oil palm crops are associated with short lifecycles and high nutrient demands, which may disproportionately affect soil health. With the goal of exploring baseline soil properties in commercial oil palm plantations, we evaluated data from two large-scale soil surveys carried out in 2014/2015 and 2018/2019 across more than 400 fields located throughout Peninsular Malaysia. We examined variation in field-measured soil quality indicators with a focus on soil organic carbon content at three depths (0-15 cm, 15-30 cm, 30-45 cm) and investigated links with spatial covariates, including plantation age. We found SOC contents to be low (1.6-2%) across the sampled locations with limited correlation with spatial predictors employed in soil organic carbon modelling. Furthermore, we found that immature and young mature plantations, which consisted of fields that were re-planted as part of a 20-year-long oil palm rotation, were characterised by significantly lower soil organic carbon content than the mature plantations. This suggests that management practices should target younger oil palm plantations for soil organic conservation measures to increase the overall baseline SOC content, which will subsequently accumulate over the plantation's lifespan. We further provide recommendations for future soil sampling efforts, which could increase the robustness of collected data and facilitate their use for soil monitoring through modelling approaches involving, for example, digital soil mapping.

    This study evaluates the effectiveness of unmanned aerial vehicles (UAVs) in monitoring coastal changes at Pantai Mengabang Telipot, Kuala Terengganu, Malaysia. Addressing the limitations of traditional monitoring methods, such as ground-based surveys and satellite imagery, the research underscores the critical need for timely and precise coastal monitoring using drone technology. The study employs a comprehensive four-phase methodology involving area identification, data acquisition through UAV imagery, data processing, and accuracy analysis. The orthophoto accuracy achieved, compared to detailed shoreline surveys, is 0.064 m. Analysis of shoreline changes over two observation periods reveals a retreat of 0.056 m per day over 14 days, escalating to 0.180 m per day during the subsequent 20 days. These findings highlight the influence of the Southwest Monsoon and man-made structures on coastal dynamics. The results contribute significantly to advancing UAV-based coastal change assessments, emphasizing their pivotal role in precision-driven decision-making for sustainable coastal management.

    BACKGROUND: Diarrhoeal diseases claim more than 1 million lives annually and are a leading cause of death in children younger than 5 years. Comprehensive global estimates of the diarrhoeal disease burden for specific age groups of children younger than 5 years are scarce, and the burden in children older than 5 years and in adults is also understudied. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to assess the burden of, and trends in, diarrhoeal diseases overall and attributable to 13 pathogens, as well as the contributions of associated risk factors, in children and adults in 204 countries and territories from 1990 to 2021.

    METHODS: We used the Cause of Death Ensemble modelling strategy to analyse vital registration data, verbal autopsy data, mortality surveillance data, and minimally invasive tissue sampling data. We used DisMod-MR (version 2.1), a Bayesian meta-regression tool, to analyse incidence and prevalence data identified via systematic reviews, population-based surveys, and claims and inpatient data. We calculated diarrhoeal disability-adjusted life-years (DALYs) as the sum of years of life lost (YLLs) and years lived with disability (YLDs) for each location, year, and age-sex group. For aetiology estimation, we used a counterfactual approach to quantify population-attributable fractions (PAFs). Additionally, we estimated the diarrhoeal disease burden attributable to the independent effects of risk factors using the comparative risk assessment framework.

    FINDINGS: In 2021, diarrhoeal diseases caused an estimated 1·17 million (95% uncertainty interval 0·793-1·62) deaths globally, representing a 60·3% (50·6-69·0) decrease since 1990 (2·93 million [2·31-3·73] deaths). The most pronounced decline was in children younger than 5 years, with a 79·2% (72·4-84·6) decrease in diarrhoeal deaths. Global YLLs also decreased substantially, from 186 million (147-221) in 1990 to 51·4 million (39·9-65·9) in 2021. In 2021, an estimated 59·0 million (47·2-73·2) DALYs were attributable to diarrhoeal diseases globally, with 30·9 million (23·1-42·0) of these affecting children younger than 5 years. Leading risk factors for diarrhoeal DALYs included low birthweight and short gestation in the neonatal age groups, child growth failure in children aged between 1-5 months and 2-4 years, and unsafe water and poor sanitation in older children and adults. We estimated that the removal of all evaluated diarrhoeal risk factors would reduce global DALYs from 59·0 million (47·2-73·2) to 4·99 million (1·99-10·0) among all ages combined. Globally in 2021, rotavirus was the predominant cause of diarrhoeal deaths across all ages, with a PAF of 15·2% (11·4-20·1), followed by norovirus at 10·6% (2·3-17·0) and Cryptosporidium spp at 10·2% (7·03-14·3). In children younger than 5 years, the fatal PAF of rotavirus was 35·2% (28·7-43·0), followed by Shigella spp at 24·0% (15·2-37·9) and adenovirus at 23·8% (14·8-36·3). Other pathogens with a fatal PAF greater than 10% in children younger than 5 years included Cryptosporidium spp, typical enteropathogenicEscherichia coli, and enterotoxigenic E coli producing heat-stable toxin.

    INTERPRETATION: The substantial decline in the global burden of diarrhoeal diseases since 1990, particularly in children younger than 5 years, supports the effectiveness of health interventions such as oral rehydration therapy, enhanced water, sanitation, and hygiene (WASH) infrastructure, and the introduction and scale-up of rotavirus vaccination. Targeted interventions and preventive measures against key risk factors and pathogens could further reduce this burden. Continued investment in the development and distribution of vaccines for leading pathogens remains crucial.

    OBJECTIVE: The management of large central giant cell granuloma (CGCG) can pose a significant surgical challenge. In such circumstances, the use of denosumab has been proposed with the literature reporting varying degrees of success. Histopathological assessment of CGCG post-denosumab treatment remains unknown. The current case series aims to address this lack of information and supplement the literature and the debate with evidence.

    STUDY DESIGN: The current case series is a retrospective review of historic cases accumulated from 3 different hospitals. Patients treated with denosumab for large or unresectable GCGC who subsequently underwent either surgical debulk or resection post drug treatment with histological tissue for assessment were included.

    RESULTS: A total of 4 patients were included in this study. All cases showed radiographic response. However histological assessment identified giant cells in 3 of the 4 cases, 2 of which showed clinical recurrence. All cases demonstrated irregular woven bone formation toward the periphery of the lesion suggesting partial response.

    CONCLUSIONS: The current case series provides some insight regarding the response of CGCG to denosumab and preliminary histopathological information toward the ongoing debate regarding the medical management of CGCG. (Oral Surg Oral Med Oral Pathol Oral Radiol YEAR;VOL:page range).

    BACKGROUND: Family planning facilities provide an extensive choice of assistance that is beneficial for women and the society. It may limit the fatality risk for mothers and babies by reducing the rate of pregnancies and abortions. The Government of Pakistan has been continuously trying to persuade the people about the importance of family planning. The accomplishment of these programs depends upon various aspects associated with the knowledge, availability, and access to contraceptives. This paper has investigated the effect of knowledge and access to contraceptives on the unmet need for family planning (UMNFP) among married women of reproductive age (MWRA) in Pakistan.

    METHOD: The comprehensive dataset of the Pakistan Demographic and Health Survey 2017-18 has been used to investigate the effect of knowledge and access to contraceptives on UMNFP among MWRA in Pakistan by applying Multivariable Logistic regression.

    RESULTS: The prevelance of UMNFP is higher among MWRA of 25 to 34 years than other age groups. The likelihood of UMNFP decreases with increase in education above the primary level. The prevalence of UMNFP is found higher among women who belong to the poorer wealth quintile than the women of the poorest wealth quintile. The odds of UMNFP are considerably low among women belonging to the richer and richest wealth quintile, compared to the women of the poorest wealth quintile. Women's participation in decision making for not using contraceptives is a significant factor to reduce UMNFP. The odds of UMNFP are higher among those women who have no knowledge and lack of access to contraceptives compared to those who have knowledge and access to contraceptives.

    CONCLUSIONS: Both knowledge and access to contraceptives are important factors to determine UMNFP. The government should initiate programs to disseminate knowledge as well as provision of contraceptives for effective family planning.

    Pathogens significantly influence natural and agricultural ecosystems, playing a crucial role in the regulation of species populations and maintaining biodiversity. Entomopathogenic fungi (EF), particularly within the Hypocreales order, exemplify understudied pathogens that infect insects and other arthropods globally. Despite their ecological importance, comprehensive data on EF host specificity and geographical distribution are lacking. To address this, we present EntomoFun 1.0, an open-access database centralizing global records of EF-insect associations in Hypocreales. This database includes 1,791 records detailing EF species, insect host taxa, countries of occurrence, life stages of hosts, and information sources. EntomoFun 1.0 is constructed based on 600 literature sources, as well as herbarium specimens of the Royal Botanical Gardens, Kew. This database is intended to test hypotheses, identify knowledge gaps, and stimulate future research. Contents of the EntomoFun 1.0 database are visualized with a global map, taxonomic chart, bipartite community network, and graphs.

    Discipline-specific terminology is a central element of the vocabulary used by dentists and scientists in the context of their professional activities and plays a critical role in the understanding of dentistry. A number of controversial terms and non-standardized definitions exist in the field of endodontology. For example, in root and canal anatomy, variations exist in the definitions of root morphology (including apical bifurcation, fusion and dilaceration), pulp chamber anatomy (including the outline of the floor, pulp horns and location of the root canal orifice), apical root canal bifurcations, canal isthmuses, accessory canals and apical foramen. This narrative review provides a critical analysis of a range of controversial terms currently used to describe root and canal anatomy. It also addresses the consequences of using such controversial terms on the accuracy and reliability of research findings and clinical practice.
