Transmigration of mandibular canines: a review of literature

Transmigration of mandibular canine is a rare entity and is defined as the phenomenon of an unerupted tooth crossing the midline. The exact cause is unknown and the transmigrated tooth usually is asymptomatic. However transmigration might compromise esthetics and occlusion. The current literature review is presented to draw attention towards prominent aspects of this anomaly in developing an understanding for managing such patients. Several electronic databases were searched. Hand searching was done to short list relevant articles. A total of 47 studies were initially retrieved out of which 35 relevant studies were selected for the review. Transmigration is a rare developmental anomaly and has been reported to affect the mandibular canines exclusively. Left side of the arch is reported to be more affected than the right and females show a greater prevalence. Transmigration of mandibular canine is an uncommon phenomenon of unknown etiology that is usually symptom less. An in-depth evaluation of transmigration would be helpful to develop significant clinical management of the affected patients

Dental arch widths in class I normal occlusion and class II division 1 malocclusion

The purpose of this study was to compare dental arch widths Class II division 1 malocclusion with normal Class I occlusion subjects. The Intercanine, Interpremolar and intermolar widths were measured on 100 dental casts [50 class I and 50 class II/1 malocclusion subjects]. The data was developed on SPSS 16 for windows. Independent-samples t-test was applied for comparison of the groups. Lower Intercanine width was larger in class II/1 malocclusion and Intermolar width was significantly increased in call I normal occlusion group. Interpremolar width between the two groups did not reveal any significant difference. Lower intercanine width was significantly larger in class II/1 and Maxillary intermolar width was significantly narrower in class II/1 malocclusion subjects

Dental arch widths in class i normal occlusion and class ii division 2 malocclusion

The purpose of this study was to compare dental arch widths in Class II division 2 malocclusion with Class I normal occlusion subjects. The Intercanine, Interpremolar and Intermolar widths were measured on 100 dental casts [50 class I and 50 class II12 malocclusion subjects]. The data were developed on SPSS 16 for windows. Independent-samples t-test was applied for comparing the two groups. Lower Intercanine and Intermolar width was larger in class III2 malocclusion group. Interpremolar width between the two groups did not reveal any significant difference. Lower Intercanine and Intermolar width was significantly larger in class II12 malocclusion than the subjects with normal class I occlusion

Class II division 2 malocclusion; cephalometric skeletal evaluation

The purpose of this study was to evaluate the cephalometric skeletal, dental and soft tissue characteristics in class II division 2 malocclusion in the sagittal and vertical dimensions. Lateral cephlaograms of 60 patients for both genders [30 class I and 30 class II/2] were used to determine the characteristics of class II div 2 malocclusion and were compared with control group class I patients. The data base was developed in SPSS 16 for windows. In sagittal plane, mandible was retrognathic in class II/2 malocclusion and demonstrated significantly reduced measurements in vertical plane, indicative of a skeletal deep bite. Upper incisors were significantly retroclined while lower incisors were normally inclined. Both upper and lower lips were protrusive
