Introduction: In orthodontic diagnosis and treatment planning it is an important goal to reach the best functional and esthetic results. However, during treatment planning the size of the teeth is a frequently ignored factor. The discrepancies of the mesiodistal widths of the teeth can be examined with the Bolton analysis. Our aim is to investigate whether the results described by Bolton are ap...

BACKGROUND Orthodontic patients show high prevalence of tooth-size discrepancy. This study investigates the possible association between arch form, clinically significant tooth-size discrepancy, and sagittal molar relationship. METHODS Pretreatment orthodontic casts of 230 Saudi patients were classified into one of three arch form types (tapered, ovoid, and square) using digitally scanned ima...

The purpose of this study was to determine the possible effect of genetic factors on Bolton tooth-size discrepancy. Subjects who applied for orthodontic treatment and their siblings (106 females and 78 males) were included in the study. The ages of the subjects ranged from 13 to 21 years. The siblings were grouped according to gender: male-male (24 pairs), female-female (38 pairs) and male-fema...

Aim: The objectives of this study were to investigate the effects of tooth extraction and air-rotor stripping therapy on tooth-size discrepancy, and to compare the changes between two groups. Materials and methods: The sample comprised the preand post-treatment dental models of 20 postadolescent class I borderline patients. First group was composed of dental models of 10 patients (mean age of 1...
