Bisphosphonates are pharmacologic compounds characterized by high tropism to bone tissue. They affect bone metabolism by inhibition of osteoclast recruitment, proliferation, differentiation, and function. Because they can reduce bone resorption, bisphosphonates are used mainly for the treatment of osteometabolic conditions. However, the use of bisphosphonates has been associated with the onset of osteonecrosis of the jaws and indication of dental implants. As a result of this, the aim of this study was to present the risks and the care that health professionals should take in cases of surgical procedures such as placement of dental implants in patients who make use of bisphosphonates.
Human identification can be performed by several methods, as anatomical structures of the facial skeletal and individuals signals. The aim of this study was to report a case of human identification from the morphological evaluation of the frontal sinus and the presence of titanium plates in skull after examination of Postero Anterior (PA) radiographs ante and postmortem. In 2008 a skull was found on a highway. Later, an alleged victim was found , who disappeared in late 2007. The skull showed postmortem teeth lost, presence of round hole in the right supra-orbital region, consistent with lesion caused by gunshot. It was also noted the presence of a miniplate of bone fixation in the form of inverted "T" in several locations of the nasal bones and bone remodeling signals in the face. PA radiograph of the skull was performed for the purpose of comparison with the X-rays provided by antemortem family. By overlapping radiographic images, there was similarity between the characteristics presented by the skull and found the alleged victim, as the frontal sinus, shape and height of the orbits, and miniplate fixation of bone with the same shape and size, not leaving no doubt that the radiographs belong to the same individual.
Purpose: This research was conducted to review the documentation and communication protocols used by dental offices and dental laboratories in the cities: Rio de Janeiro (RJ) and Araçatuba (SP), focusing on legal aspects of this practice, through a questionnaire with open and structured questions. The answers were subjected to statistical analysis with Chi-square and Fisher´s exact test, and showed that there is no agreement in the literature regarding documentation and communication protocols between the observed samples, as well as the perception of this practice by the interviewed, making evident the need to rethink the aspects that work through the relationship between dental offices and dental laboratories.
Rich in detail, the jaw is a bone that may be useful in determining the sex of the individual, because it features presents a high degree of sexual dimorphism. However, studies that correlate this trait with other individual characteristics have been little discussed, and because of this the aim of the study was to evaluate the influence of facial biotype and dental status in sexual dimorphism, by morphometric analysis of human jaw. 900 panoramic radiographs were evaluated. Facial biotype of the individuals had been previously determined by clinical exams and clinical records of the panoramic radiographs.For inclusion in the sample were selected panoramic radiographs with age group 11-91 years (±43.3 years). The measurements were made in specific software and adjusted according to the magnification of the panoramic imaging. Only one researcher performed the measurements. On both sides, the following measurements were performed: gonial angle, antegonial angle, antegonial depth, posterior curvature of the mandibular branch, depth of mandibular incisure. Differences between the right and left sides of the mandible, sex and facial biotype of the individual were subject to analysis of variance (ANOVA) to verify the sample groups difference. After we applied the Tukey-LSD test to describe the significant differences of the groups. The logistic regression test was performed showing a setting of appropriate model by Hosmer & Lemeshow test and Chi-square tests. The analysis of variance (ANOVA) showed no statistically significant differences between the sides of any measures, considering the other conditions (sex, dental condition and facial biotype). There were no statistically significant differences between the sexes and age groups. The results of regression showed that the gonial angle and age did not influence the sex determination by the model proposed, and, were not considered. The accurate prediction of the sex considering the targeted model in relation to the facial biotype is 63.7%. Have no influence of the dental status in the model, and the accuracy rate was higher in total dentate (71.3%). In conclusion, the mandibular change in gonial and antegonial regions occurs mainly according to dental status and sex.
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.
