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...
LAMM syndrome (OMIM #610706) is a rare autosomal recessive syndrome characterized by the association of Michel aplasia, microdontia and malformation of the external ear. Different mutations in FGF3 gene were reported in several families presenting with this syndrome. Clinical features and genetic results observed in a family with LAMM syndrome are reported. The diagnosis of isolated Michel apla...
of an earlier human species (Homo erectus) in its size, robusticity, and lack of chin. It also shows features that ally it with later species, such as the relatively small teeth. While initially suggested as an ancestor for the Neanderthals, similarities were later noted between Mauer and remains from Arago (France), which are in turn often grouped with comparable MidPleistocene fossils from Eu...
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...
