    Even though variety of foreign bodies has been reported in a various locations in the craniofacial region, wooden foreign bodies are uncommon. Appropriate management of wooden foreign bodies is considered essential because of their infectious complications and difficulty in radiographic localization. Even though literature is replete with articles on management of foreign bodies in the craniofacial region, specific management of wooden foreign bodies are rarely reported. The purpose of this article is to report two cases of deeply placed wooden foreign body and a protocol for managing them in the maxillofacial region.

    OBJECTIVES: The objectives of this study were to determine the prevalence and clinical characteristics of torus palatinus (TP) and torus mandibularis (TM) in Malaysian dental patients.
    METHODS: Thousand five hundred and thirty-two dental patients were examined for the presence of oral tori at the Faculty of Dentistry outpatient clinic, AIMST University. Factors such as race, age, sex, size, and shape of tori were studied.
    RESULTS: The prevalence rates were 12% for TP and 2.8% for TM. A variation in the presence of tori among the three races in Malaysia-Chinese, Malays, and Indians-was noted, where the Chinese significantly had a higher prevalence of TP (17.9%) and TM (4.6%). Predominantly, tori were observed >40 years and older age group, and further both TP and TM were seen more commonly in women. Most TP were of smooth type (52.2%) and >2 cm (67.4%), while all TM were bilateral and nodular, plus most were <2 cm (67.4%).
    CONCLUSION: Presence of tori (TP and TM) was detected in 12.5% of the participants. The variations noted in the prevalence and clinical characteristics of tori among people of different races living in the same country reflect its multifactorial etiology. Both genetic and environmental factors are responsible for its occurrence, and particular races are more prone genetically where its expression is enhanced by environmental factors.

    BACKGROUND: Bilateral sagittal split osteotomy (BSSO) is the most versatile procedure and adopted by many surgeons to relocate the mandible in patients having mandibular prognathism (MP). Injury to the inferior alveolar nerve (IAN) and unfavorable splits are two surgical complications of BSSO which are associated with mandibular morphology. Uses of cone beam computed tomography (CBCT) in providing 3-D images has gained a wider acceptance in surgical field nowadays. Its advantages are including reduced cost, lesser radiation dose and smaller physical footprint comparing to the conventional computed tomography.

    PURPOSE: This study aims to identify the differences in morphology of prognathic and non-prognathic mandible at BSSO sites using cone beam computed tomography images.

    METHODS: This retrospective study involved 51 CBCT images of patients having mandibular prognathism and without mandibular prognathism. The latter group made up from patients with Class I skeletal pattern. Samples were taken using purposive sampling method from two clinical centers.

    RESULT: Prognathic mandible has higher lingula level, superiorly and buccally placed inferior alveolar nerve canal at distal second molar, thinner mediolateral width of ramus at anterior and posterior part and thinner anteroposterior width of the ramus.

    CONCLUSION: Morphology of mandible in patients with mandibular prognathism (MP) was significantly different from patients without mandibular prognathism (WMP) for most of the parameters. The high risk parameters may be highlighted to the patients using cone beam computed tomography images.

    Crouzon syndrome exhibits considerable phenotypic heterogeneity, in the aetiology of which genetics play an important role. FGFR2 mediates extracellular signals into cells and the mutations in the FGFR2 gene cause this syndrome occurrence. Activated FGFs/FGFR2 signaling disrupts the balance of differentiation, cell proliferation, and apoptosis via its downstream signal pathways. However, very little is known about the cellular and molecular factors leading to severity of this phenotype. Revealing the molecular pathology of craniosynostosis will be a great value for genetic counselling, diagnosis, prognosis and early intervention programs. This mini-review summarizes the fundamental and recent scientific literature on genetic disorder of Crouzon syndrome and presents a graduated strategy for the genetic approach, diagnosis and the management of this complex craniofacial defect.

    Introduction: Oral tori and exostosis are non-pathological bony protuberances seen on the alveolar surfaces of the jaw bones. These are commonly seen on the palatal surfaces of the maxilla [torus palatinus (TP)] and around the premolars in the lingual surface of the mandible [torus mandibularis (TM)]. The aim of this cross-sectional study was to determine the prevalence of tori/exostosis in the Malaysian population.

    Methodology: A total of 2666 patients were examined for the presence of tori and exostosis in the maxilla and mandible and were categorized into TP, TM, and exostosis (facial/labial). Collected data was analysed for obtaining descriptive statistics.

    Results: 882 subjects were noticed with oral tori/exostosis among the population studied with a prevalence rate of 33%. TP was seen more in females (35%), compared to males (20%), and this difference was statistically significant (p value

    Introduction: Scientific literature suggests that human papillomavirus (HPV) infection may be associated with oral squamous cell carcinoma (OSCC). However, knowledge regarding HPV-OSCC link among oral health professionals (OHP) has been insufficient. So, the aim of this study was to assess the knowledge about HPV associated OSCC among OHP working in dental faculties in Malaysia.

    Methodology: Ethical committee of the University approved this study. A validated, pre-tested questionnaire was sent electronically to 224 OHP. Questionnaire collected information regarding demography, knowledge about HPV-OSCC link, HPV vaccine, and willingness to educate patients about HPV OSCC link among the participants of this cross-sectional study. Data collected was analysed using "Stata/IC-13" and was summarised using descriptive statistics like frequency, percentage, mean and standard deviation.

    Results: Out of 179 participants, around 39% of the participant's opined virus was not a causative factor for OSCC. Around, 44% replied posterior portion of the tongue/oro-pharynx was the commonest site for HPV related OSCC, whereas 29% replied that lateral border of the tongue was the common site for HPV related OSCC. Forty one percent educated patients regarding HPV infection being a causative factor for OSCC. HPV vaccine can prevent OSCC was stated by 70% OHP. Only 12% were aware of the availability of HPV vaccine in Malaysia. Majority (99%), agreed that there is a need to offer continuing education programmes to dentists highlighting advances and preventive strategies in the fight against OSCC.

    Conclusion: Substantial increase in awareness is required among OHP regarding HPV-OSCC link.

    Manipulation of dental stem cells (DSCs) using current technologies in tissue engineering unveil promising prospect in regenerative medicine. DSCs have shown to possess angiogenic and osteogenic potential in both in vivo and in vitro. Neural crest derived DSCs can successfully be isolated from various dental tissues, exploiting their intrinsic great differentiation potential. In this article, researcher team intent to review the characteristics of DSCs, with focus on their angiogenic and osteogenic differentiation lineage. Clinical data on DSCs are still lacking to prove their restorative abilities despite extensive contemporary literature, warranting research to further validate their application for bone tissue engineering.

    The case reported here highlights the importance of examination of functional occlusion along with static occlusion. Any undetected malocclusion during early mixed dentition has potency to alter the growth and function of stomatognathic system. Premature contacts in primary canine region is the most prevalent cause of functional mandibular shift and can lead to TMJ problems for the prevalence of self correction of such malocclusion is very low if not intervened. A case of functional mandibular shift due to faulty canine guidance because of premature contacts is discussed here. Selective grinding of premature contacts and myofunctional exercise resulted in well balanced centric occlusion coinciding with centric relation.

    Introduction: Elusive second mesiobuccal canal (MB2) in maxillary first molar are often missed during endodontic therapy and are a major cause of treatment failures. Its prevalence is known to vary among different populations and there is limited information on its prevalence in Indian population.

    Aim: This study investigated the prevalence and location of second mesiobuccal (MB2) canal in mesiobuccal root of maxillary first molar using cone beam computed tomography (CBCT) images in an Indian population.

    Materials and methods: CBCT images of 598 three rooted maxillary first molars were studied. In each CBCT image, the floor of pulp chamber was located and advanced by 2 mm to standardize the observation for MB2 canal. Its location was determined in relation to mesiobuccal (MB1) and palatal (P) canal.

    Statistical analysis: The data was analysed using descriptive statistics. The presence of MB2 canal was correlated with age, gender and tooth position using Chi square test.

    Results: The prevalence of MB2 canal in three rooted maxillary first molar was 61.9%. It was seen that the prevalence of MB2 was highest in 20-40years age group (67.4%) followed by > 40 years (57.5%) and lowest in <20 years (50.6%) and the difference was statistically significant (p = 0.005). It is located mesiopalatally; 2.5 mm ± 0.6 mm palatally and 1.0 ± 0.4mmmesially to the MB1 canal or present directly on the line joining the MB1 and palatal canal.

    Conclusion: There is a high probability of finding MB2 canal in Indian patients. The access cavity must be modified from a triangular shape to rhomboid shape. Troughingmesiopaltally (about 2.5 mm palatally and 1 mm mesially) from MB1 to a depth of about 2 mm from the floor of pulp chamber may be necessary for locating MB2 canal.

    Introduction: Integrated curricula are being increasingly adopted in health professions, owing to their advantages including patient-centred training and development of critical thinking. Similarly, the majority of dental Universities have either moved away from discipline-specific towards integrated curricula or have incorporated elements of integration. Despite several advantages offered by the integrated curriculum, one disadvantage is failure to assess depth of knowledge. Assessing the depth of knowledge is a characteristic of discipline-specific curriculum. This commentary describes the inclusion of both discipline-based and integrated assessments at Faculty of Dentistry, SEGi University, Malaysia.

    Material and methods: Module tests (discipline-based assessments) comprising of discipline specific questions are conducted at the end of every term, mimicking the traditional discipline-specific assessment. Questions in the module tests are intended to assess the depth of knowledge of students. Mid semester examinations are conducted at the end of the semester, mimicking the integrated assessment. Integrated questions are intended to test the breadth of knowledge of students.

    Results: Lecturers and students felt introduction of module tests, helped them to prepare for topics in a phased manner and better answer questions posed by lecturers during case discussions and clinical presentations. The 'borderline distinction' students felt that studying for module tests provided them with the depth of knowledge essential to answer questions during viva voce.

    Discussion: Including both the traditional and integrated methods of assessments would engage students in a learning experience developing their breadth and depth of knowledge. Further prospective research is essential to assess the impact of this assessment strategy.
