The frequency of accessory mental foramina (AMF) was studied in four population groups: 20th century Asian Indians, African Americans and American Whites, and Pre-Columbian Nazca Indians. AMF were found less frequently in the American White and Asian Indian populations than in the other groups (American White, 1.4%; Asian Indian, 1.5%; African American,… (More)
The purposes of this study were threefold: (i) to assess the degenerative changes of the temporomandibular joint [TMJ (condyles and articular eminence of the glenoid fossa)], (ii) to determine whether the TMJ degeneration levels differ by ethnic group and gender and (iii) to assess the association between the angles of eminentia and TMJ degeneration, while… (More)
The benefit and implications of blood pressure (BP) measurement in dental patients are a standard curricular component of most physical evaluation courses in dental schools. However, previous research has indicated that preventive procedures such as oral cancer examinations frequently are not completed or documented. A survey of practicing dentists was… (More)
The occurrence of retromolar foramina (RMF) was examined in a sample of dry skulls (African American n = 249; Causcasian n = 226) to consider the potential clinical impact. A prevalence rate of 7.8% of RMF was found. There were no statistical differences based on race or gender. The prevalence may contribute to the explanation of a portion of inferior… (More)
An incidence of tori lower than previously reported was found in a population from Pre-Columbian Peru. It is suggested that the prevalence of tori along with other genetic markers with racial variation may be used to help identify and define a population group.
An unusual case of odontogenic carcinoma with dentinoid is presented and discussed. This case is the first reported to show this peculiar histologic picture. The lesion recurred following what was deemed adequate surgical excision from both the clinical and histologic viewpoints. Adequate therapy and follow-up for such lesions is thus stressed.
Plants traditionally employed for the treatment of malaria in certain areas of Brazil, where this disease is prevalent, were surveyed by interviewing natives and migrants in the Amazon Region. Forty-one plants used for malarial treatment and/or for the related symptoms (fever and liver disorders) were collected and identified. Given the potential of… (More)
The retromolar foramen (RMF) was found to occur in eighteen of 234 adult human mandibles studied (7.7%). No statistically significant difference was found between left and right sides or between sexes. A statistical correlation was made between the occurrence of the RMF and accessory mandibular foramina, accessory mental foramina, mandibular third molars,… (More)
