Titanium and its alloys are mainly used in manufacturing dental implants. The fact that titanium implants are immunologically very effective, new methods are being experimented to achieve utmost success rate as a biomaterial. One fundamental indicator for clinical achievement of implant is the decision of composition decided for the implant with the objective to improve osseointegration. The main objective of this study was to explore literature on dental materials used for implants, contrast them with titanium dental implants, with the aim to improve osseointegration and mechanical quality using Ti–Ga–Si dental implant.
Background: Interproximal contact areas in primary teeth are known to be broader, flatter, and situated more gingivally than in permanent teeth. The objective of the present study was to evaluate the different types of intact interproximal contact areas in primary teeth using cone beam computed tomography (CBCT) among children.
Methods: A cross-sectional study was designed with 74 contacts from 28 existing CBCT images of children aged between 3 and 14 years, obtained from the Indian Dental Education Academy, Chennai, India. The shape of the contact area was observed at three levels, the coronal, middle, and apical thirds, in three different sections of CBCT. Prevalence of the types of contact areas was expressed in the form of numbers and percentages.
Results: The weighted Cohen’s kappa values for inter-examiner reliability was 0.893 at baseline. Results exhibited four different types of contact areas between the primary molars, namely, O type, X type, I type, and S type, based on the shapes observed; hence, the proposed classification is referred to as OXIS. The most common pattern seen was I (66.2%), followed by X (21.6%), O (9.4%) and the least common was S (2.7%).
Conclusion: The three-dimensional evaluation of intact interproximal contact areas between primary molars are of four types, O,X, I and S.
Introduction: Studies conducted among fishermen shows that there was a high prevalence rate in Oral mucosal lesions. However, data on oral health care needs among fisherman is scarce. Hence this was undertaken to obtain a data that can be used to plan programmes for the prevention and treatment of such oral mucosal lesions in the fishermen.
Materials and Methods: A study was carried out among 71 fishermen after obtaining clearance from the institutional ethical committee and concerned authorities. A self administered questionnaire is distributed among the study group comprising questions relating to personal history and deleterious habits. Clinical examination was carried out using mouth mirror, explorer and under proper illumination. Oral health examination was done using WHO Basic Oral health Assessment proforma, 2013. Data collected and analysed statistically using SPSS software.
Results: Among the 71 fishermen, 56(78.9%) were males and 15 (21.1 %) were females. In the study population, 44(62%) were tobacco chewers, 39(54.9%) were snuff users, 24(33.8%) were alcohol consumers and 19(26.8%) were smokers. Smokeless tobacco (41.5%) was the most common deleterious habit after which by alcohol consumption (33.8%) and smoking (26.8%).The prevalence of oral mucosal lesions was 20.8%.It was found that statistically significant association existed between the deleterious habits and leukoplakia.
Conclusion: According to the our study, the prevalence of oral mucosal lesions was 20.8% among the fishermen who had a clear association with deleterious habits such as tobacco chewing, smoking, alcohol consumption and snuff.
Cementoblastoma is a benign true neoplasm which forms a mass of cementum or cementum-like tissue on the root surface of the tooth. As a maxillofacial practitioner, it is essential to consider cementoblastoma as one of the differential diagnosis, although rare, while considering maxillary swellings. The treatment remains fairly conservative, with an excellent prognosis.
Ultrasonography is a non-invasive diagnostic tool for OSMF. It could be a better diagnostic tool compared to clinical and histopathological examination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
