BACKGROUND: Osteoma is a benign osteogenic lesion characterized by the proliferation of compact or cancellous bone. Although this tumour has a considerable incidence, there are few reports with large samples on this subject. OBJECTIVES: To describe clinical features of the osteomas in the craniomaxilofacial region. MATERIAL AND METHODS: Retrospective study of 106 patients diagnosed with 132 osteomas of the craniomaxilofacial region between 1986 and 2003. RESULTS: The mean age was 50 years. Osteomas were more frequent in men. Forty-nine per cent were of peripheral type, 29% central osteomas and 21% were located in the paranasal sinuses. Eighty-nine cases (84%) were operated and 80 patients were regularly followed up. Out of these, 73 did not recur. The seven recurrences were central osteomas. CONCLUSIONS: Osteomas usually appear in patients with more than 30-year old. Peripheral type showed the highest incidence among these lesions. Central and peripheral osteomas usually do not originate clinical symptoms whereas the ones located in paranasal sinuses can provoke headache and neuralgia/paresthesia.
MG3 showed the smallest range of changes in players' performance, suggesting improved fit, comfort, and acceptation compared with MG2. Furthermore, its greatest advantage is the individualized design according to the proper anatomy of the oral cavity. Greater efforts must be made to improve the comfort of MGs if their use is to be increased.
The prevalence of peri-implantitis in private practice patients enrolled in a periodontal maintenance programme was estimated to be between 12% and 22%. Almost 40% of the patients had mucositis. These prevalences are similar to those published in University environment samples.
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.
