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 < 0.001). Highest prevalence of TP was seen in Malays (43%), followed by Chinese (31%) and Indians (21%), which was statistically significant (p value < 0.00). Discussion: High prevalence of tori and exostosis was seen in the population studied. Though harmless, in certain circumstances, their presence necessitates changes in the denture design during fabrication of prosthesis, which the dentist should be mindful.

“…Although relations between age and exostosis, and gender and exostosis have reported, 35,36 some studies indicate an insignificant difference in prevalence between genders. 37 In this study there wasn't any relation and the reason could be our limited study population. Both of exostoses and enostoses usually do not require treatment.…”

Aim: Oral mucosa, tongue, dentition and bone are important parameters for oral and systemic health care. A wide variety of lesions and conditions, either harmless or harmful, can affect the oral cavity. Identification and treatment of these conditions are an important part of oral health care. The aim of this study was to evaluate the general oral health status, by assessing the prevalence and types of mucosal, tongue, dental and jaw lesions, in a group of patients. Materials and methods: This study was conducted in a group of 314 dental outpatients. Participants' oral mucosal, tongue, dental, jaw lesions and their locations were recorded. Data were analyzed using logistic regression analysis. Results: Three hundred and fourteen patients (40.1% female, 59.9% male), 148 (47.1%) of whom exhibited one or more mucosal lesions, 40 (12.7%) tongue lesions, 242 (77.1%) one or more acquired dental conditions, 61 (19.4%) one or more dental anomalies, and 22 (7.0%) bone manifestations in the jaws. The most commonly detected mucosal lesions were Fordyce's granules (20.1%), linea alba buccalis (16.9%), melanoplakia (15.9%), and frictional keratosis (2.5%). Fissured tongue (8.0%), geographic tongue (1.6%), lingual varicosity (1.3%) and coated tongue (1.3%) were the most commonly determined tongue lesions. The most commonly detected dental anomalies were hypodontia (6.1%), microdontia (4.1%), dilaceration (4.1%), and enamel hypoplasia (2.5%). Exostoses (4.1%), enostoses (1.0%) and fibro-osseous lesions (1.0%) were the most commonly detected bone manifestations in the jaws. Conclusion: Oral mucosal and tongue lesions could be a sign of systemic diseases and also could form a base for oral cancers. In this study oral mucosal lesions and tongue lesions prevalence were high but fortunately all the detected conditions were harmless, benign conditions. This emphasizes the importance of familiarity, awareness, and differentiation of these lesions and conditions to avoid unnecessary treatments.Key words: Oral health, oral mucosal lesions, tooth anomalies, tongue lesions ÖZET Amaç: Oral mukoza, dil, dentisyon ve çene kemikleri ağız ve genel sağlığın önemli parametreleridir. Zararlı ve zararsız birçok lezyon ve durum oral kaviteyi etkileyebilir. Bu durumların tespit ve tedavileri ağız ve genel sağlığın önemli bir parçasıdır. Bu çalışmanın amacı, bir grup hastanın ağız sağlığı durumlarının mukoza, dil, diş ve çene lezyonlarının prevalans ve tipleri değerlendirilerek belirlenmesidir. Gereç ve yöntem: Bu çalışmaya diş hekimliği fakültesine başvuran 314 hasta katıldı. Katılımcıların oral mukoza, dil, diş ve çene kemiklerindeki lezyonlar ve bu lezyonların lokalizasyonları kaydedildi. Veriler lojistik regresyon modeli oluşturularak incelendi. Bulgular: Üç yüz on dört hastanın (%40.1 kadın, %59.9 erkek), 148'inde (%47.1) bir veya birden fazla mukoza lezyonu, 40'ında (%12.7) dil lezyonu, 242'sinde (%77.1) kazanılmış bir veya birden fazla dental patoloji, 61'inde (%19.4) bir veya birden fazla diş anomalisi ve 22'sinde (%7.0) kemik lezyon...

“…An occlusal supporting zone must have at least 1 contact between a tooth and its antagonist in order to be counted. In this study, patients were grouped based on a modified version of EI 15 : Class A had contacts in 4 support areas; Class B in 1-3 areas or in the anterior area only; Class C, with few if any remaining teeth, had no contact in any area.…”

Background. The mandibular cortical index (MCI) is a measurement based on the visual assessment of changes in the morphology of the mandibular cortex on panoramic radiographs.Objectives. The present study aimed to investigate age, gender, dental status (DS), occlusal function, and presence of torus mandibularis (TM) as variables that might have a possible effect on MCI.Material and methods. A total of 381 patients (155 men and 226 women) aged 21-84 years (mean age: 43.8 ±14.5 years) were included in this study. Age, gender and DS were recorded for each patient. The occlusal function was evaluated using the Eichner index (EI). The presence of tori was assessed by visual inspection and digital palpation. The MCI assessments were done based on Klemetti's classification (C1-C3). Statistical comparisons were performed using the χ 2 test, independent samples t-test and multiple logistic regression analysis (p < 0.05).Results. Significant differences were observed between the MCI categories regarding age, gender, DS, EI, and TM. The likelihood of the MCI categories C2 and C3 was increased in males (odds ratio (OR) 9.33; p < 0.001), when TM was absent (OR 2.73; p < 0.001), in EI Class B (OR 2.68; p = 0.027), and in the age group 50-70 years (OR 2.5; p = 0.018). Conclusions.Morphological changes of the mandibular cortical bone are related to gender, presence of TM, occlusal function expressed as EI, and age.
