Chronic smoking can lead to failure of Osseo integration due to decrease in local blood flow and failure of cell proliferation by by-products of smoking. This along with immediate failure of a malpositioned implant, devitalization of adjacent tooth necessitating a call for endodontic treatment or the fracture of the adjacent tooth due to malpositioned implant, fracture of the prosthesis due to ...

Electron paramagnetic resonance (EPR) has been successfully used as a physical technique for gamma radiation dose reconstruction using calcified tissues. To minimize potential discrepancies between EPR readings in future studies, the effects of cavity response factor, tooth position and donor gender on the estimated gamma radiation dose were studied. It was found that the EPR response per sampl...

OBJECTIVES To compare tooth size between subjects with mild, moderate and severe hypodontia and a control group. MATERIAL AND METHODS The study comprised 120 patients with hypodontia divided into three groups of 40 mild (≤2 teeth congenitally missing), 40 moderate (3-5 teeth congenitally missing) and 40 severe (≥6 teeth congenitally missing) hypodontia; and 40 age and sex matched controls. To...

Tooth size varies exponentially with body weight in primates. Logarithmic transformation of tooth crown area and body weight yields a linear model of slope 0.67 as an isometric (geometric) baseline for study of dental allometry. This model is compared with that predicted by metabolic scaling (slope = 0.75). Tarsius and other insectivores have larger teeth for their body size than generalized pr...

BACKGROUND Researchers have conducted extensive studies regarding dentoalveolar factors that affect anterior dental esthetics; however, there is no consensus regarding laypeople's perspectives on these factors. METHODS The authors conducted a systematic search of electronic databases (MEDLINE, PubMed, Embase, Cochrane Library and Web of Science) until May 2010. They identified and selected ar...

Introduction: Predicting the size of unerupted teeth during the mixed dentition period is a critical factor in managing the developing occlusion. The Nance radiographic method, Moyers mixed dentition space analysis and Johnston Tanaka method are among the most commonly used in clinical practice for detecting tooth sizearch length discrepancies. In view of reported secular trends, racial, and se...

Analysis of variation in tooth size in a population of red fox, Vulpes vulpes (Linnaeus, 1758) from Poland based on three indices (coefficient of variation CV, variation index VSD, residual standard deviation RSD) and its correlation with average tooth size revealed two contradictory patterns. The CV and VSD were significantly correlated with average tooth sizes, while RSD values was independen...
