BACKGROUND:Although numerous studies have documented malocclusion in various age groups in India, the literature on the prevalence of malocclusion in mixed dentition is scanty. Dental caries is another most common condition affecting the general health. However, its association with malocclusion in mixed dentition is not well known.AIM:The purpose of this study was to establish the prevalence of malocclusion and its association with caries experience in 8–9-year-old children of Davangere city, South Indian region.SETTING AND DESIGN:The study design was a cross-sectional survey.MATERIALS AND METHODS:A total of 800 children from 350 schools (both males and females) were randomly selected for the study. t-test and Chi-square test were used for statistical analysis.RESULTS:The overall prevalence of malocclusion among 8–9-year-old children was 40.9%. The most prevalent malocclusion was crowding (11.5%), followed by excessive overjet (9.4%), deep bite (6.8%), spacing (6.5%), crossbite (4.5%), and open bite (3.2%). Class I molar relationship prevailed in 95.5% of children.CONCLUSION:The prevalence of malocclusion in our study was in accordance with the other studies reported in India, which ranged from 19.6% to 90%. Furthermore, correlation of malocclusion and dental caries in the primary dentition, although nonsignificant, presented children with malocclusion to have a higher caries experience than children without malocclusion.

This is a case report of an 11-year-old male patient in whom a mesiodens from a donor was used as an allotransplant to replace his missing central incisor. The treatment results over 1 year showed successful periodontal healing and functioning of the allotransplanted tooth. The aim of this paper is to report a procedure, allotransplantation of tooth, which is followed from ages but less preferred and documented and is surrounded by variable prognosis and also highlight the use of a mesiodens, which in any case has to be extracted and usually of no other use.

Background. This paper reports a case with end-on-molar relation with maxillary anterior teeth proclination, lower anterior teeth crowding, and deep bite. The case was successfully treated in a short span. Clinically significant improvement in the dimensions of the maxillary and mandibular dental arch forms and sufficient space for the eruption of permanent teeth was observed. Conclusion. Therefore, it can be concluded that preorthodontic trainer is a valid treatment of choice in mixed dentition where transverse expansion is a part of the treatment plan, as the results obtained are within short period of time and have less chances of relapse, because the correction of a malocclusion is by elimination of soft tissue dysfunction.
