Mostly asymptomatic, it can result in functional and esthetic problems. The aim of the present study was to determine the prevalence of talon cusp in the North Indian population. Materials and Methods: The data was collected from the radiographic examination of 6048 periapical films showing 18,754 teeth from a random sample of 3320 patients attending the Department of Oral Medicine and Radiology. A tooth with a superimposed V-shape radiopaque structure was considered having a talon cusp. Results: Talon cusp was detected in 122 teeth with a tooth prevalence of 0.65. Maxillary lateral incisors were the most commonly affected teeth (86 teeth, 70.5%), followed by maxillary canines (24 teeth, 19.7%) and maxillary central incisors (12 teeth, 9.8%). None of the patients had talon cusp in the mandibular teeth. The person prevalence was estimated at 2.95. Bilateral talon cusp was found in 24 patients. Conclusion: Talon′s cusp is a rare clinically evident dental anomaly. Careful observation during the routine dental examination can help in the early diagnosis of talon cusp and associated anomalies. This can help prevent the associated treatment problems and further complications.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115100479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: A total of 5486 impacted third molars of 4133 patients were studied through the panoramic radiographs and clinical records to determine the position of the impacted third molars and for the presence of associated pathology. The ages of the patients ranged from 17 years to 67 years, with a mean of 33.7 years. The ratio of male to female patients was 1.8:1. The ratio of maxillary to mandibular molars was 1:1.6. Results: Pericoronitis was the most common associated pathology with the third molars (38.9%), followed by dental caries seen in 13.2% of the impacted teeth. Cystic and neoplastic changes were seen around 3.6% impacted teeth and 5.3% adjacent second molars had caries. Other pathologies were less frequent. Conclusion: The prevalence of pathological conditions associated with the third molar in the Western Indian population was 69.73%. Pericoronitis and caries were commonly seen in relation to the impacted third molars, whereas cystic pathology and root resorption were rarely observed. The fact that a considerable number of patients were asymptomatic indicating pathology is certainly worth considering.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115348401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A laborious and tedious manual sequence, tissue processing is of paramount importance for having good thin sections without artefacts. Tissues and cells examined outside the body with an imaging system are an artefact of the original. The structure of a tissue is determined by the shape and size of macromolecules in and around the cells. Histopathology is a comparative science where like is compared with like and like with unlike. Various techniques have been developed to prepare tissues for study so that they closely resemble their natural, living state. Biopsied tissue has to be stained for microscopical examination. The tissues have to be enabled for sectioning, and the series through which it is prepared is called tissue processing. This review article highlights the three methods of tissue processing and their benefits. The review was selected by typing tissue processing in the Google search engine, Pubmed, and Pubmed Central. Literature review of articles reflecting different methods, variation from the conventional tissue processing method, and latest technique to enhance the quality of the tissue to be processed was performed.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: The implant was modeled as a non-osteointegrated Ti-6Al-4V standard mini-screw, implanted in the anterior-buccal region of human jaw. 3D realistic models were constructed using data based on micro-computed tomography scans of human teeth as found in the literature. A couple of self-balanced forces of 4 N was applied and finite element method analysis was run and produced an approximate solution, which allowed to display stress distribution over the whole model. Materials′ behavior was assumed elastic and linear. This approximation applies to the 1 st stage of the orthodontic treatments. Results: A detailed qualitative and quantitative analysis of the stress state is presented through images. Results in terms of stresses and displacements were studied to exclude any possibility of bracket debonding, bone failure, and loss of stability of the screw. Results were compared to the ultimate strengths of the bio-materials involved using engineering failure criteria. The actual stress state was found to be lower than the critical values. Conclusion: Results allows to qualitatively see the amount of bone, surronding the mini-screw, and the tooth, that undergoes stress. Furthermore, quantitative analysis of stress could exclude failure in alveolar bone and detachment at the enamel-bracket interface. The applied force and devices were proved to be safe to use for this kind of orthodontic facilities.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127364650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: A retrospective chart review was performed of all cases of BIs diagnosed in the Department of Oral Radiology in West China College of Stomatology, Sichuan University. The data collected included age at diagnosis, gender, race, location, presenting symptoms, type of BIs. Results: In radiographic evaluation, BIs appear as localized, well-defined, non-expansile, radiopaque masses, which are round, elliptic or irregular in shape and are of variable size, ranging from a few millimetres to about 2 cm in diameter. The results of this study generally supported previous findings that BIs have an overwhelming mandibular predilection, especially, in the pre-molar/molar region, no sex predilection. Conclusions: The presumptive diagnosis of a BI can easily be made if the individual clinical and radiologic findings, together with follow-up examinations, are taken into account. In addition, it is important to recognize this anomaly, evaluate radiographies carefully and distinguish it from other bone variations such as primary or metastatic tumours, which is much more significant clinically in dental examinations.","PeriodicalId":359264,"journal":{"name":"Journal of Cranio-Maxillary Diseases","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129850670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
