OBJECTIVES To provide a description of mesiodistal crown diameters (MD) and tooth-size discrepancy (TSD) of the permanent dentition in patients with thalassemia major (TM) and to compare the results with those of unaffected control group. STUDY DESIGN The sample consisted of 46 thalassemic patients, 25 males and 21 females aged 7.3 to 23.7 years (mean ± SD = 11.2 ± 3.9 years) and control grou...

Tooth size and arch dimensions are hereditary factors that play a role in the occurrence of crowding teeth. The purpose this study was to determine difference tooth between This type research is an observational with cross sectional approach. sample consisted two groups. dental model, which 36 pairs each group. results showed total mesio-distal width maxillary anterior teeth (45.95 mm 48.26 mm)...

This study aimed to assess and compare the overall and anterior ratios of tooth size discrepancies in all Angle malocclusion groups. The following null hypothesis (H0) was tested: no difference between tooth size discrepancies (overall and anterior) would be observed among Angle malocclusion groups. The sample comprised of 711 pre-orthodontic treatment study casts of Brazilian patients with a m...

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...
