ROMERO ZALDIVAR, Esperanza C; PEREZ CEDRON, Ricardo  and  BANGO DE VARONA, María Josefa. Analysis of Bolton´s Anterior Index and its relationship with some occlusal variables. AMC [online]. 2010, vol.14, n.6, pp.1-8. ISSN 1025-0255.

Background: the relationship of mesiodistal diameters of teeth may influence in the characteristics of malocclusions and in the prognosis of treatments. Objective: to determine the frequency and association of the Bolton´s anterior index with some occlusal variables. Methods: a cross-sectional descriptive study was conducted in patients with malocclusion that began their treatments at Ismael Clark y Mascaró Provincial Teaching Odontology Clinic of Camagüey city, from June to December 2008. The universe was constituted by 72 patients, the sample remain conformed by 25 who completed the inclusion criteria. Patients were examined in the dental armchair; occlusal variables were determined and to patients were carried out the necessary dental measures to establish the Bolton´s anterior index. Results: the proportion distribution of the Bolton´s anterior index was not uniform, the one of “dental inferior excess " was the most frequent. Conclusions: statistical difference was not presented in the overjet, the overbite, neither in the Angle´s classification related to the Bolton´s index; in the combination of dental arcade characteristics, vestibuloversion of the upper and inferior normal arcade was the most frequent, with significant statistical difference in relation to the other combinations.
