“…All specimens were fixed in 10% neutral buffered formalin. Graphic reconstructions were based on published procedures (Burdi, 1968;Garn et al, 1979) for two-dimensional graphic reconstructions of frontally-sectioned histologic tissues. Serial sections (from 10 to 15 gm each) were stained with a Masson Trichrome connective tissue stain.…”

This study deals with correlations of tooth size in human primary teeth. Traditionally, mesiodistal or buccolingual measurements have been used to express crown size. However, in this study, crown area was used as a reference parameter.Graphic reconstructions of 38 histologically prepared human fetuses with Crown-Rump Length (CRL) between 54 and 280 mm were used to obtain linear and area measurements. Based on clinical records and physical examinations, these fetuses were considered typical-for-age, or "normal". Correlation matrices indicated high levels of concordance among all developing deciduous tooth crowns and arch measurements. It was concluded that crown area is a statistically better trait to use in comparison of teeth rather than the traditional mesiodistal measurement.

a b s t r a c tOrthodontists are interested in finding a set of standard arch forms for clinical orthodontic practice. In this paper, we propose a functional clustering method for the dental arches based on a mixture of U-shaped curves. We decide the number of clusters (equivalently, mixture components) using the Bayesian information criterion and the jump criterion based on a given distortion function. We apply our method to clustering the dental arch data from the nationwide standard occlusion study conducted in Korea from 1997 to 2005. The data are composed of dental arches of 306 subjects with normal occlusion selected from 15,836 young adults. We also provide the comparison of the proposed method to other existing methods.

“…The dimensions of the dental arch are related to individuals and to evolutionary factors such as an increase in intercondylar distance of the cranial base. The arch form is determined during the embryonic period (BURDI, 1968).…”

The aim of this study was investigate the association between the mandibular arch morphology and the facial type of Brazilian Caucasians with natural normal occlusion. For this, we used a sample comprised of lateral radiographs and respective dental casts of 51 individuals (21 male and 30 female), presenting at least 4 of the 6 Andrews' keys to normal occlusion without previous orthodontic treatment. Angle's first molar relationship was considered indispensable for the sample. The facial type was defined by two cephalometric measurements (SN.SGn and SN.GoGn). After scanning the models (3D) and radiographs, the images were evaluated by 12 orthodontists. A modified Kappa test evaluated the agreement between examiners to classify the morphology of the dental arch. The chi-square test was used to verify the association between the facial type (dolichofacial, mesofacial, or brachyfacial) and the dental arch morphology (square, oval, or tapered), using significance level of 5%. Casual and systematic errors (p > 0.05) showed no significant results and the Kappa test showed significant agreement among examiners for the dental arch form (0.55) with a p < 0.001, considered as 'moderate'. The chisquare test indicated no significant association. The null hypothesis was accepted, as the facial type was not associated with dental arch morphology in individuals with normal occlusion.
