Khamis MF, Taylor JA, Malik SN, Townsend GC

Forensic Sci Int, 2014 Jan;234:183.e1-7.
PMID: 24128748 DOI: 10.1016/j.forsciint.2013.09.019

Information about the sex of individuals is important for human identification. This study was conducted to quantify classification rates of sex prediction models for Malaysians using odontometric profiles. Mesiodistal (MD) and buccolingual (BL) crown dimensions of the permanent dentition were studied in 400 young adult Malaysians, giving a total of 28 tooth size variables. The sample consisted of three major ethnic groups, the Malays, Chinese and Tamils, since the aim was to assess sex dimorphism in Malaysians as a whole. Results showed that the mesiodistal diameter of the lower canine was the most sexually dimorphic dimension in Malaysian Malays and Tamils. Univariate analyses showed that the magnitude and pattern of sex dimorphism varies between these three ethnic groups, with Malaysian Chinese and Tamils being more dimorphic than the Malaysian Malays. Stepwise discriminant functions were generated bearing in mind their application in practical forensic situations. The range of classification rates was from 70.2% to 78.5% for the composite Malaysian group, and 83.8%, 77.9%, 72.4% for Malaysian Chinese, Malays and Tamils, respectively. The 'Area Under the Receiver Operating Characteristic Curve statistics' indicated good classification rates for three prediction models obtained using a combination of all tooth size variables, mandibular teeth, and mesiodistal dimensions in the composite Malaysian group, and for all tooth size variables in each ethnic group. The present study provides strong support for the value of odontometry as an adjunct scientific method for sex prediction in human identification.

Masood M, Yusof N, Hassan MI, Jaafar N

Asia Pac J Public Health, 2014 May;26(3):260-7.
PMID: 22218936 DOI: 10.1177/1010539511420704

The aim of this 5-year longitudinal cohort study was to assess the prevalence, severity, and trends in caries increment and impact of the School Dental Incremental Care Programme (SDICP). Data were gathered from school dental records as part of the SDICP. A sample of 1830 children were included and checked for caries experience annually using World Health Organization criteria. In total, 95.4% of the children were caries free in 2004, and caries experience declined to 70.5% in 2009 with an average of 4.9% annually. At baseline, the mean DMFT (confidence interval [CI]) was 0.06 (0.05-0.08) and increased to 0.58 (0.53-0.63) in 2009. Children with active caries were 4.4% in 2004, and figures rose to 9.6% in 2009. The FT component increased most rapidly during these 5 years from 0.2% to 25.1%. Overall caries prevalence and increment was low in this study. Proportions of FT component were higher as compared with DT component with low rate of extractions during the latter years of the study.

Dental therapists: a global perspective

Nash DA, Friedman JW, Kardos TB, Kardos RL, Schwarz E, Satur J, et al.

Int Dent J, 2008 Apr;58(2):61-70.
PMID: 18478885

In 1921, New Zealand began training school dental nurses, subsequently deploying them throughout the country in school-based clinics providing basic dental care for children. The concept of training dental nurses, later to be designated dental therapists, was adopted by other countries as a means of improving access to care, particularly for children. This paper profiles six countries that utilise dental therapists, with a description of the training that therapists receive in these countries, and the context in which they practice. Based on available demographic information, it also updates the number of dental therapists practising globally, as well as the countries in which they practice. In several countries, dental therapy is now being integrated with dental hygiene in training and practice to create a new type of professional complementary to a dentist. Increasingly, dental therapists are permitted to treat adults as well as children. The paper also describes the status of a current initiative to introduce dental therapy to the United States. It concludes by suggesting that dental therapists can become valued members of the dental team throughout the world, helping to improve access to care and reducing existing disparities in oral health.

Application of third molar development and eruption models in estimating dental age in Malay sub-adults

Mohd Yusof MY, Cauwels R, Deschepper E, Martens L

J Forensic Leg Med, 2015 Aug;34:40-4.
PMID: 26165657 DOI: 10.1016/j.jflm.2015.05.004

The third molar development (TMD) has been widely utilized as one of the radiographic method for dental age estimation. By using the same radiograph of the same individual, third molar eruption (TME) information can be incorporated to the TMD regression model. This study aims to evaluate the performance of dental age estimation in individual method models and the combined model (TMD and TME) based on the classic regressions of multiple linear and principal component analysis. A sample of 705 digital panoramic radiographs of Malay sub-adults aged between 14.1 and 23.8 years was collected. The techniques described by Gleiser and Hunt (modified by Kohler) and Olze were employed to stage the TMD and TME, respectively. The data was divided to develop three respective models based on the two regressions of multiple linear and principal component analysis. The trained models were then validated on the test sample and the accuracy of age prediction was compared between each model. The coefficient of determination (R²) and root mean square error (RMSE) were calculated. In both genders, adjusted R² yielded an increment in the linear regressions of combined model as compared to the individual models. The overall decrease in RMSE was detected in combined model as compared to TMD (0.03-0.06) and TME (0.2-0.8). In principal component regression, low value of adjusted R(2) and high RMSE except in male were exhibited in combined model. Dental age estimation is better predicted using combined model in multiple linear regression models.

Copper vapour laser ID labelling on metal dentures and restorations

Ling BC, Nambiar P, Low KS, Lee CK

J Forensic Odontostomatol, 2003 Jun;21(1):17-22.
PMID: 12793127

Denture marking is accepted as a means of identifying dentures and persons in geriatric institutions, or post-mortem during war, crimes, civil unrest, natural and mass disasters. Labelling on the acrylic resin component of the denture can easily be damaged or destroyed by fire but on cobalt-chromium components it would be more resistant. A copper vapour laser (CVL) can be used to label the cobalt-chromium components of dentures and metal restorations easily, and legibly, and miniaturised for the incorporation of more personal particulars necessary for the identification of the deceased person. The CVL beam is focussed by its optics and delivered to the material surface by the two-axis scanner mounted with mirrors. A personal computer controls the movement of the scanner and the firing of the CVL. The high peak power of the pulsed CVL is focussed to very high energy density producing plasma ablation of the alloy surface. Very fine markings of a few microns width can be produced enabling the storage of detailed information of the deceased person on a metal surface for the purpose of rapid identification.

Caries prevalence in different racial groups of schoolchildren in West Malaysia

Yassin I, Low T

Community Dent Oral Epidemiol, 1975 Aug;3(4):179-83.
PMID: 1056826

A dental health survey of 15,197 schoolchildren age 6-18 years was conducted in West Malaysia. The caries experience in the permanent teeth of the three racial groups, namely Malay, Chinese and Indian/Pakistani, showed a distinct variation. The prevalence was highest among the Chinese children, being about twice that of the Malay and Indian/Pakistani children. In the primary dentition, however, the caries experience in the three racial groups was comparable. An analysis of the factors contributing to the racial variation showed that dietary influence was not the only factor responsible. The possibility of a racial variation in caries susceptibility has been postulated. In the primary dentition the similar caries experience observed in the three groups of children was most probably due to the widespread occurrence of rampant caries which would heavily weight the dift score of the children in all three groups. The need to fluoridate the public water supply as an effective preventive measure is emphasized.

Compendium of Oral Science, 2019;6(1):26-34.
MyJurnal

Objective: To assess if the recall appointments and the use of radiographs for paediatric dental patients at Faculty of Dentistry, UiTM comply with current guidelines. Materials and Method: A retrospective study was conducted using patients’ dental records that were registered at the Faculty of Dentistry UiTM. The sample consisted of 350 randomly chosen treatment records of paediatric patients aged between birth and 16 years of age at the time of data collection which was in the year 2016. Data collection included demographic details, whom the cases were treated by, caries risk assessment, radiographs taken and time taken for the patient’s review appointments. Results: An initial sample size of 350 records were assessed. The mean age of patients seen when they were first seen is 6.3 years old. Caries Risk Assessment was not reported in majority of the cases (58%,). Baseline radiographs were taken in 44.6% of the cases. For the assessment of recall attendance, only samples with data on CRA was analysed (n=145). The review appointments at 3 months interval was 70% whereas at 6 months was 6.2% and one year recall was 6.7%. A chi-square test showed significant difference (p=0.013) between the category of operators for the 1-year review whereby review was higher among students and specialists as compared to dental officers. Conclusion: This study shows poor adherence to the recommended recall protocol as suggested by NICE and AAPD guidelines. Further studies need to be done to assess the patients’ and clinicians awareness regarding the recall protocol and determine the problems causing poor recall attendance.

Ahmad MS, Mokhtar IW, Khan NLA

J Int Soc Prev Community Dent, 2020 05 18;10(3):323-328.
PMID: 32802779 DOI: 10.4103/jispcd.JISPCD_74_20

Context: Oral health inequalities experienced by patients, including people with disabilities (PWD), have been related to dentists' lack of professionalism and inadequate experience in managing patients with special needs.
Aims: This study investigated the impact of an extramural program involving PWD on dental students' professionalism and students' perception of training in managing patients with special needs.
Materials and Methods: A group of 165 undergraduate dental students (year 1 to year 5) participated in a voluntary program, involving 124 visually impaired children, at a special education school in Kuala Lumpur, Malaysia. A dedicated module in oral health was developed by specialists in special care dentistry, pedodontics, and medical sciences. Dental students then participated in a semi-structured focus group interview survey to discuss perceptions of their learning experiences. Qualitative data were analyzed via thematic analysis.
Results: The program had positive impact on various aspects categorized into four major domains: professional knowledge (e.g., understanding of oral-systemic-social-environmental health interaction and understanding of disability), professional skills (e.g., communication and organizational skills), professional behavior (e.g., empathy and teamwork), and value-added learning (e.g., photography and information technology skills). Students showed improved willingness to manage, and comfort in managing PWD, and expressed support for future educational programs involving this patient cohort.
Conclusion: Improved knowledge, skills, attitudes, and personal values, as well as support for future programs, indicate the positive impact of extramural educational activities involving PWD in developing professionalism in patient care, while providing an opportunity for students to be exposed to managing patients with special needs.

Malhotra N

Curr Stem Cell Res Ther, 2019;14(4):351-366.
PMID: 30636614 DOI: 10.2174/1574888X14666190111105504

OBJECTIVES: A variety of bioreactors and related approaches have been applied to dental tissues as their use has become more essential in the field of regenerative dentistry and dental tissue engineering. The review discusses the various types of bioreactors and their potential application in dentistry.
METHODS: Review of the literature was conducted using keywords (and MeSH) like Bioreactor, Regenerative Dentistry, Fourth Factor, Stem Cells, etc., from the journals published in English. All the searched abstracts, published in indexed journals were read and reviewed to further refine the list of included articles. Based on the relevance of abstracts pertaining to the manuscript, full-text articles were assessed.
RESULTS: Bioreactors provide a prerequisite platform to create, test, and validate the biomaterials and techniques proposed for dental tissue regeneration. Flow perfusion, rotational, spinner-flask, strain and customize-combined bioreactors have been applied for the regeneration of bone, periodontal ligament, gingiva, cementum, oral mucosa, temporomandibular joint and vascular tissues. Customized bioreactors can support cellular/biofilm growth as well as apply cyclic loading. Center of disease control & dip-flow biofilm-reactors and micro-bioreactor have been used to evaluate the biological properties of dental biomaterials, their performance assessment and interaction with biofilms. Few case reports have also applied the concept of in vivo bioreactor for the repair of musculoskeletal defects and used customdesigned bioreactor (Aastrom) to repair the defects of cleft-palate.
CONCLUSIONS: Bioreactors provide a sterile simulated environment to support cellular differentiation for oro-dental regenerative applications. Also, bioreactors like, customized bioreactors for cyclic loading, biofilm reactors (CDC & drip-flow), and micro-bioreactor, can assess biological responses of dental biomaterials by simultaneously supporting cellular or biofilm growth and application of cyclic stresses.

PMID: 33670465 DOI: 10.3390/ma14040954

Glass ionomer cement (GIC) is a well-known restorative material applied in dentistry. The present work aims to study the effect of hydroxyapatite (HA) addition into GIC based on physical, mechanical and structural properties. The utilization of waste materials namely clam shell (CS) and soda lime silica (SLS) glass as replacements for the respective CaO and SiO2 sources in the fabrication of alumino-silicate-fluoride (ASF) glass ceramics powder. GIC was formulated based on ASF glass ceramics, polyacrylic acid (PAA) and deionized water, while 1 wt.% of HA powder was added to enhance the properties of the cement samples. The cement samples were subjected to four different ageing times before being analyzed. In this study, the addition of HA caused an increment in density and compressive strength results along with ageing time. Besides, X-ray Diffraction (XRD) revealed the formation of fluorohydroxyapatite (FHA) phase in HA-added GIC samples and it was confirmed by Fourier Transform Infrared (FTIR) analysis which detected OH‒F vibration mode. In addition, needle-like and agglomeration of spherical shapes owned by apatite crystals were observed from Field Emission Scanning Electron Microscopy (FESEM). Based on Energy Dispersive X-ray (EDX) analysis, the detection of chemical elements in the cement samples were originated from chemical compounds used in the preparation of glass ceramics powder and also the polyacid utilized in initiating the reaction of GIC.

The Heritability of Palatal Rugae Morphology Among Siblings*, †

Chong JA, Syed Mohamed AMF, Marizan Nor M, Pau A

J Forensic Sci, 2020 Nov;65(6):2000-2007.
PMID: 32692413 DOI: 10.1111/1556-4029.14507

Although there is clinical applicability of the palatal rugae as an identification tool in forensic odontology, controversy exists whether the palatal rugae patterns are stable or variable. The greater the genetic component, the higher the probability that palatal rugae patterns are stable. The aim of this study was to compare the palatal rugae morphology between full siblings and the proportion of variability due to genetic component. This cross-sectional study was conducted on digital models of 162 siblings aged 15-30 years old. The palatal rugae patterns were assessed with Thomas and Kotze (1983) classification using Geomagic Studio software (3D Systems, Rock Hill, SC). The palatal rugae morphology between siblings showed significantly similar characteristics for total number of left rugae (p = 0.001), left primary rugae (p = 0.017), secondary rugae for right (p = 0.024) and left sides (p = 0.001), right straight rugae (p = 0.010), and right convergent rugae (p = 0.005) accounting for at least 6.25%-12.8% of the variability due to heredity. Despite the similarities found, the palatal rugae patterns showed significant differences between siblings of at least 46.9% (p = 0.001). Zero heritability was found in 9 of the 14 rugae patterns. Meanwhile, total number of rugae, primary, backward, and convergent rugae showed moderate heritability (h2 > 0.3) and total number of secondary rugae showed high heritability (h2 > 0.6). In conclusion, despite the individuality characteristics, an appreciable hereditary component is observed with significant similarities found between sibling pairs and the palatal rugae patterns were both environmentally and genetically influenced.

Archives of Orofacial Sciences, 2006;1(1):15-20.
MyJurnal

Dentistry has searched for an ideal material to place in osseous defects for many years. Endogenous bone replacement has been the golden standard but involves additional surgery and may be available in limited quantities. Also, the exogenous bone replacement poses a risk of viral or bacterial transmission and the human body may even reject them. Therefore, before new biomaterials are approved for medical use, mutagenesis systems to exclude cytotoxic, mutagenic or carcinogenic properties are applied worldwide. The present preliminary study was carried out in five male New Zealand white rabbits (Oryctolagus cuniculus). Porous form of synthetic hydroxyapatite granules (500 mg), manufactured by School of Materials and Mineral Resources Engineering, Universiti Sains Malaysia, Penang, was implanted in the femur of the rabbits. Blood samples were collected prior to implantation and one week after implantation. The blood was cultured in vitro and the cell division was arrested at metaphase using colcemid. This was followed by the hypotonic treatment and fixation. Then, the chromosomes were prepared and stained for analysis. The modal chromosome number of rabbit (Oryctolagus cuniculus) was found to be 2n=44. The mean mitotic index values prior to and after implantation were 3.30 ± 0.66 and 3.24 ± 0.27 per cent respectively. No gross chromosome aberrations, both numerical and structural were noticed either prior to or after implantation of the biomaterial. These findings indicate that the test substance, synthetic hydroxyapatite granules does not produce gross chromosome aberrations under the present test conditions in rabbits.

MyJurnal

The aim of this study was to determine the profile of patients referred to a specialist oral medicine and oral pathology unit in Kuala Lumpur by reviewing clinical dental records received in Oral Pathology Diagnostic Service (OPDS) in Faculty of Dentistry, UKM from 2001 until 2010. A total of 547 archival biopsy clinical dental records were reviewed and analysed using SPSS version 17.0. Oral and maxillofacial diseases were frequently seen in female (1.3:1), young adults (30.0%) of Malay ethnicity (64.6%). Most of the acquired specimens were from dental specialists (n=451, 84.8%), particularly from oral and maxillofacial surgeons (OMFS) (n=349, 63.8%) compared to general dental practitioners (GDPs) (n=81, 14.8%). Almost all of the biopsy specimens were of soft tissue origin (n=462, 84.4%), derived from lining mucosa (n=197, 36.0%) and were biopsied excisionally (n=325, 59.4%) more often than by incisional biopsy (n=207, 37.8%). A large proportion of the oral and maxillofacial diseases were of reactive (n=188, 34.4%) and inflammatory (n=121, 22.1%) cause. Tumours are mainly benign (n=69, 12.6%) with only small cases are malignant (n=34, 6.2%). The most common histological diagnoses were accounted by mucocele (n=56, 10.2%), pyogenic granuloma (n=47, 8.6%), fibroepithelial polyp (n=38, 6.9%), radicular cyst (n=33, 6.0%) and periapical granuloma (n=29, 5.3%). This study characterizes the clinical profile of patients seen in our oral medicine and oral pathology unit. Present findings can be used as a reference to the clinicians and pathologists in effective patient management and organization in the future.

Green dentistry: the art and science of sustainable practice

Mulimani P

Br Dent J, 2017 Jun 23;222(12):954-961.
PMID: 28642517 DOI: 10.1038/sj.bdj.2017.546

Dentistry is highly energy and resource intensive with significant environmental impact. Factors inherent in the profession such as enormous electricity demands of electronic dental equipment, voluminous water requirements, environmental effects of biomaterials (before, during and after clinical use), the use of radiation and the generation of hazardous waste involving mercury, lead etc have contributed towards this. With rising temperatures across the world due to global warming, efforts are being made worldwide to mitigate the effects of environmental damage by resorting to sustainability concepts and green solutions in a myriad of ways. In such a scenario, a professional obligation and social responsibility of dentists makes it imperative to transform the practice of dentistry from a hazardous to a sustainable one, by adopting environmental-friendly measures or 'green dentistry'. The NHS in the UK has been proactive in implementing sustainability in healthcare by setting targets, developing guidance papers, initiating steering groups to develop measures and implementing actions through its Sustainable Development Unit (SDU). Such sustainable frameworks, specific to dentistry, are not yet available and even the scientific literature is devoid of studies in this field although anecdotal narratives abound. Hence this paper attempts to present a comprehensive evaluation of the existing healthcare sustainability principles, for their parallel application in the field of dentistry and lays out a blueprint for integrating the two main underlying principles of sustainability - resource use efficiency and eliminating or minimising pollution - in the day-to-day practice. The article also highlights the importance of social values, community care, engaging stakeholders, economic benefits, developing policy and providing leadership in converting the concept of green dentistry into a practised reality.

Fulltext Knowledge, attitude and practice on preventive dentistry among senior dental students in Yemen

Mohammed Ali Mohammed Al-Wesabi, Zaleha Md Isa

Int J Public Health Res, 2015;5(1):560-568.
MyJurnal

Introduction There is a strong and increased worldwide interest on the aspects of
prevention of oral disease and oral health promotion in dental education.
However, some studies imply that dental students are not knowledgeable
enough in this issue. This study aimed to evaluate the knowledge of, attitude
towards and practice on preventive dentistry among senior dental students in
Yemen.

Methods Self-administered questionnaires were distributed among senior dental
students in six dental schools in Yemen. The questionnaire obtained personal
information, and questions about knowledge on preventive dental care,
attitudes towards and practice on preventive dentistry.

Results Among 346 students who filled the questionnaire, a total of 91.6% has good
knowledge about fissure sealant effectiveness, only 34.7% knows about the
importance of fluoride toothpaste compared to brushing technique in
preventing caries, with significant gender difference (p=0.005). Odds of good
knowledge among non-Qat chewers was 1.9 (95%CI: 1.26-4.42).
Multivariable regression analysis indicated that female gender was associated
with higher positive attitudes (OR: 2.03, 95%CI:1.21-3.36,p=0.007).
Attitudes were significantly associated with Qat chewing (OR = 1.95,
95%CI: 1.04-3.66, p=0.03), type of university (OR = 0.59, 95%CI: 0.36-0.94,
p=0.02), and mothers' level of education (OR = 1.91, 95%CI: 1.05-3.47,
p=0.03). There was a high percentage of competency in practicing preventive
measures among students (80.9%).

Conclusions Dental education should emphasize the overall aspects of preventive dentistry
with early exposure of preventive dental training in order to improve
students' knowledge and attitudes and consequently practice on preventive
care.

INTRODUCTION: Special Care Dentistry (SCD) education has been introduced in Malaysia, but there are limited number of studies about its impact to students. Thus, this study aimed to explore the level of students' readiness to treat people with learning disability (PWLD) based on their attitudes, self-efficacy and intention to treat.
METHODS: A questionnaire was developed based on the Dental Student Attitude to the Handicapped Scale, Scale of Attitudes to the Disabled Persons and Health Action Process Approach. The self-administered, validated questionnaire was tested for reliability (Cronbach's alpha = .71-.81), before being distributed to clinical dental students of both genders from two universities (University A, n = 176 and University B, n = 175). Quantitative data were analysed via t test and ANOVA (p

Clinical pathways in primary dental care in Malaysia: clinicians' knowledge, perceptions and barriers faced

Tay HL, Raja Latifah RJ, Razak IA

Asia Pac J Public Health, 2006;18(2):33-41.
PMID: 16883968 DOI: 10.1177/10105395060180020601

The Oral Health Division, Ministry of Health in Malaysia piloted clinical pathways (cpath) in primary care in early 2003. This study investigated the knowledge, perception of cpaths and barriers faced by the clinicians involved in the pilot project. Self-administered questionnaires were sent to the clinicians (n=191). Dentists (67.9%) and dental nurses (70.6%) had good overall knowledge of cpaths. The majority of the clinicians (67.9% to 95.6%) perceived cpath positively in all areas. Only 9.2% of dentists encountered difficulties in using cpath forms compared to 28.4% of dental nurses. A higher proportion of dental nurses (73.5%) compared to dentists (64.8%) were willing to continue using cpath. The majority of dentists (76.7%) and dental nurses (73.1%) were willing to participate in future development of cpaths. Overall, there was evidence of managerial support for the pilot project. A follow-up of the pilot project was somewhat lacking as less than half (43.3%) of the clinicians reported that the state coordinator obtained feedback from them. The findings auger well for the future implementation of cpath should the Oral Health Division decide to adopt cpath routinely in the public oral health care service.

Racial variations in the extent of tooth root translucency in ageing individuals

Whittaker DK, Bakri MM

Arch Oral Biol, 1996 Jan;41(1):15-9.
PMID: 8833585

One hundred and ninety-eight single-rooted teeth from individuals aged 21-90 yr of Caucasian, Malay, Chinese Malay and Indian Malay origin were studied. Single or serial longitudinal sections of extracted teeth were cut following dye imbibition of patent dentinal tubules. The extent of sclerosis of apical dentinal tubules was assessed and correlated with the age of the individual. Correlation with age was higher in the Caucasian than the Malay races and within the Malaysian racial groups correlation with age was highest in the Malays and lowest in the Chinese. It is concluded that factors other than age may be important in the formation of sclerotic apical dentine in teeth of different racial origin. The effect of racial origin should be considered when using sclerosis as a means of age determination in forensic cases.
