Aim: To evaluate possible differences of the upper and lower dental arches width among youths with Class I,normal occlusion and Class II, division 1 malocclusion. Materials and Methods: The evaluation was conducted on 100 pairs of dental casts of Bangladeshi youths with permanent dentition, 50 with Class I, normal occlusion (22 males and 28 females) at the mean age of 19±3 years and 50 with Class II, division 1, malocclusion (18 males and 32 females ) at the mean age of 20±4 years. The group with Class II malocclusion was divided into two categories: Class II without dental crowding and Class II with dental crowding. A comparison was made between the intercanine inter first premolar and intermolar widths of both dental arches. Results: Subjects with Class II, division, 1 malocclusion when compared with Class I normal occlusion presented (a) in the upper dental arch , smaller intermolar, interpremolar and intercanine width. (b) in the lower dental arch , smaller intermolar width. DOI: http://dx.doi.org/10.3329/bjodfo.v2i2.16159 Ban J Orthod & Dentofac Orthop, April 2012; Vol-2, No.2, 18-23

ABSTRACT Objective: To determine whether apical base size is related to dental crowding. Materials and Methods: Digital scans of dental casts were taken of 75 untreated Class I adults to measure maxillary and mandibular tooth size, dental arch perimeters, intermolar widths, and intercanine widths. Cone beam computed tomography (CBCT) images were used to measure the apical base of the maxilla and mandible, including the total cross-sectional area, five basal arch perimeters and five basal arch widths. Principal components factor analyses were performed to evaluate the relationships between the apical base size and tooth-size-arch-length discrepancies (TSALD). Results: The dental arch and maxillary apical base measures were significantly larger in males than females. There were only limited sex differences in mandibular apical base size. The dental arch measurements were smaller in subjects with greater upper and lower TSALD. Maxillary and mandibular apical base dimensions were positively interrelated. Low-to-moderate correlations were found between the size of the maxillary apical base and TSALD. The size of the mandibular apical base was not related to upper or lower TSALD. Tooth size showed little to no relationship with TSALD. Conclusions: Although maxillary apical base size is related to maxillary and mandibular crowding in subjects with Class I malocclusion, mandibular apical base size is not.

Introduction. A proportional relationship between the maxillary and mandibular teeth size is required for achieving good finish with proper overjet and overbite postorthodontic treatment. The aims and objectives of this study were to determine the anterior and overall Bolton’s ratio in Nepalese population, to compare Bolton’s ratio between subjects with normal occlusion, Class I malocclusion, and Class II malocclusion, to compare these results with Bolton’s norm, and to determine the frequency of clinically significant (beyond 2 SD) tooth size discrepancy compared to Bolton’s norm. Materials and Methods. The study models of the subjects with normal occlusion and Angle’s Class I malocclusion and Class II malocclusion and fulfilling the inclusion criteria were retrieved from department archives. An electronic digital caliper was used to measure mesiodistal tooth size of the maxillary and mandibular teeth anterior to the second molars. The study sample of 120 study models consisted of the normal occlusion group (n = 31), Class I malocclusion group (n = 47), and Class II malocclusion group (n = 42). These measurements were then used to obtain Bolton’s ratio in three groups of subjects. Bolton’s ratio of study groups was compared with each other and with Bolton’s original ratio. Results. The differences in tooth size ratio of the study groups were not significant statistically, when the groups were compared on the basis of malocclusion or gender. Statistically significant differences were exclusively observed between the study groups and Bolton’s original sample for the anterior ratio. The frequency of the clinically significant tooth size ratio discrepancy was lower for the overall ratio (9.1%) compared to the anterior ratio (22.5%). Conclusions. Bolton’s analysis on the Nepalese population sample shows that there was no significant difference observed on the anterior and overall tooth size ratios when these were compared based on Angle’s malocclusion classes or gender. The clinically significant anterior tooth size discrepancy was more prevalent than that of the overall ratio.

It is essential to know the tooth crown size to provide accurate diagnosis and treatment planning to ensure the satisfactory outcome of orthodontic treatment. The aim of the present study was to measure and compare mesiodistal crown diameter of a Kurdish sample in Erbil city with normal and different classes of malocclusion. The mesiodistal tooth width was measured by an electronic digital caliper on a total of 150 (75 males and 75 females) orthodontic models of secondary school students of different occlusal relationships (Class I normal occlusion, Class I, Class II division I, Class II division II, and Class III malocclusions). The results showed that (1) the maxillary right first molar was significantly larger than the left one and both maxillary right lateral incisors and first premolars were larger than their contralateral teeth at the level of P < 0.01. (2) Both upper and lower canine were significantly smaller in females than in males; (3) Class I malocclusion showed tendency toward larger teeth than the rest of the other occlusal categories; (4) no statistically significant differences in tooth size were found among the Class II division I, division II, and Class III malocclusions when compared to normal occlusion. In conclusion, females had smaller teeth than males and there was asymmetry between the right and left sides in tooth size and Class I malocclusion showed tendency toward larger teeth.

Aim: The purpose of this investigation was to examine the extent to which arch dimension or tooth size contributes to dental crowding. Materials and Methods: Two groups of dental casts were selected. Each group consisted of 30 pairs of dental casts including equal male and female samples. The first group had Class I malocclusion without crowding. The second group exhibited Class I malocclusion with dental crowding (more than 5 mm space deficiency). The following parameters were measured and used to compare the two groups: individual and collective mesiodistal widths of tooth, dental arch length, as well as buccal and lingual dental arch widths in the canine and molar regions. Results: Statistically significant differences in both tooth widths and transverse arch dimensions (widths) were found between the crowded and the normal groups. The crowded group was found to have a significantly smaller maxillary arch width and larger tooth size when compared with the uncrowded or normal group. There were no significant differences in arch length in the two groups in either the maxilla or the mandible. In comparing the anterior and overall Bolton ratios no significant difference was detected between the crowded and normal groups. Conclusion: The results of this study suggest under under two study groups (Class I skeletal base of crowded and uncrowded group) tooth size has a greater role in developing dental crowding.
