In order to establish standard norms for the Pakistani population, we investigated the geomorphometrics of tooth size and arch dimension using a conventional digital caliper (DC) and a digital stereomicroscope (SM). The sample consisted of 128 subjects ranging in age from 18 to 24 years. A total of 44,155 variables were measured. Dental models of each subject for maxillary and mandibular arches were scanned via Hirox digital stereomicroscope for the fabrication of the digital models, and the geomorphometrics of tooth size and arch dimensions were measured via SM scanned digital models. All the measurements were also carried out via DC on plaster dental models. Sex differences and changes associated with methods were assessed, and interrelationships between different variables were explored within the study group. For the data obtained by DC and SM techniques, the men had significantly larger arch dimensions and geomorphometrics of tooth size than the women did. There were no significant disparities observed between the techniques. The developed norms for the mesiodistal, buccolingual, diagonal tooth sizes and arch dimension had significantly greater values for males in relation to females (*pd" 0.05 to ***pd" 0.001). This study has established a new reference database of tooth size and arch dimensions via both DC and digital SM for first time on Pakistani population. These norms will be helpful for clinical treatment planning in dentistry. Contemporaneously, the norms will be of great value to forensic dentists and dental anthropologists for making comparisons within and between different populations.

“…These images were subjected to several comparisons between different expert professionals, which classified them into three basic shapes (quadrangular, triangular and oval), as suggested by several authors. [4][5][6]21 In relation to the sex, studies have affirmed that men have dental arch 16,22 and teeth larger than women. 16 Souza et al 6 (1997), evaluating a population of women between 20 and 25 years old, have observed the triangular shape of the upper central incisor as the most common (45.9%), followed by quadrangular (40.5) and oval (13.6).…”

Aim: The purpose of this study was to verify the association between the facial type and the morphology of the upper central incisor, to potentially provide a guide for artificial tooth selection in esthetic and prosthetic rehabilitation. Materials and methods:The sample consisted of 51 lateral teleradiographs (lateral cephalometric radiographs) and cast models of subjects with a naturally optimal occlusion and at least four of the six keys of Andrews, for optimal occlusion. The facial type was defined by two cephalometric measurements (SN.Gn and SN.GoGn) and classified into dolichofacial, mesofacial and brachyfacial after digitizing the radiographs. The incisor morphology was classified into quadrangular, oval and triangular after 3D digitizing the models and evaluation of the images by 12 dentists. The evaluation between the examiners was performed by Kappa test. In order to test the differences between the variables, it was used a chi-square test (5%). Results:No significant difference (p < 0.05) was found between the studied variables. Conclusion:Facial type was not associated with the morphology of the upper central incisor, considering the methodology and population included in the present study.Clinical significance: Using the facial type as a way to select the morphology of the upper central incisor proved to be inadequate in this study.

“…[2][3][4] Es sabido que existen asociaciones positivas entre las dimensiones del arco facial y dental, relaciones que se deben tomar en consideración cuando se hacen intentos para modificar el tamaño del arco dental como parte de un tratamiento de ortodoncia. 5 Existen muchas formas de realizar la medición de los anchos transversales. Uno de los métodos utilizados es tomando el centroide en el caso de caninos; 6 y las cúspides mesiovestibulares en el caso de molares.…”

de anchos intercaninos e intermolares en escolares con dentición mixta, Comuna de Contulmo, Chile. J Oral Res 2013; 2(2): 64-67.Resumen: Introducción: El éxito del tratamiento ortodóncico temprano se fundamenta en el conocimiento del desarrollo de la dentición, por lo cual la medición de sus dimensiones en los diferentes estadios de desarrollo se considera como un factor predictor para el tratamiento y rehabilitación de la población. Objetivo: Conocer y evaluar las características cuantitativas de los anchos intercaninos e intermolares según sexo en la población de niños de 6 a 8 años de la Escuela Artística San Luis de Contulmo. Metodología: Estudio cuantitativo, no experimental, de corte transversal, descriptivo y correlacional. La población de estudio correspondió a 48 alumnos de 6 a 8 años seleccionados por muestreo por conveniencia, a los cuales se les tomó modelos de estudio, midiendo y comparando los anchos intercaninos e intermolares. Resultados: Los promedios resultantes de las mediciones efectuadas fueron: distancia intercanina maxilar 33,2 ±2,6 mm en hombres y 32,2 ±2,3 mm en mujeres, respectivamente la distancia intercanina mandibular 27,1 ±2,3 mm y 26, 6 ±1,9 mm, la distancia intermolar maxilar 51,9 ±3,1 y 51,2 ±3,0 mm y la distancia intermolar mandibular 46 ±2,6 y 44,8 ±3,0 mm. Conclusión: Las diferencias entre los anchos intercaninos e intermolares según sexo no son significativas, en cuanto a la edad se observan diferencias significativas entre los 6 y 8 años en el sexo masculino, no así en el femenino. Este estudio representa un interesante punto de partida para el análisis y discusión de futuras investigaciones.
