Context. Occlusion in primary teeth varies among children of different populations and races. Aim. To assess and compare the occlusal characteristics and spacing in primary dentition among 3-6-year-old Dravidian children. Materials and Methods. The study included 2281 school going children. The primary molar relation, canine relation, overjet, and overbite were assessed using Foster and Hamilto...

Crude cell-free preparations of Botrytis cinerea were found to oxidize straight-chain primary alcohols (except methanol), aromatic primary alcohols, and unsaturated primary alcohols. The resulting products were the corresponding aldehydes and an equal molar quantity of hydrogen peroxide.

introdouction: impacted mandibular third molar surgery may affect periodontal status of the adjacent second molar. the purpose of this study was to evaluate the changes in periodontal health parameters distal to the adjacent second molar following surgical extraction of an impacted mandibular third molar. materials and methods: we selected 50 subjects with a mean age of 22.8 (ranging from 18 to...

PURPOSE The purpose of this study was to assess the associations between dental treatment in the early primary dentition and later treatment in the primary and permanent teeth. METHODS Delta Dental Plan of Michigan insurance claims data on 9,886 children who were born in 1990 and were covered by dental insurance from 1990-1998 were used. Risk ratios (RR), screening test measures of sensitivit...

E ctopic eruption of the permanent first molar is a local eruption disturbance in the developing permanent dentition. This abnormal eruption pattern is most commonly seen in the maxillary arch. The abnormal mesioangular eruption path of the maxillary first molar causes resorption of the distal root of the adjacent primary second molar. Progression of ectopic eruption may cause impacted permanen...

An unerupted mandibular second primary molar first was observed in a healthy male 3 years, 4 months of age. The report presents the rationale to allow the first permanent molar to erupt fully. The treatment objectives are presented with the description of the fixed appliances used to accomplish the objectives.

Molar incisor hypomineralization (MIH) is a developmental defect of dental enamel that shares features with hypomineralized second primary molars (HSPM). Prior to permanent tooth eruption, second primary molars could have predictive value for permanent molar and incisor hypomineralization. To assess this possible relationship, a cross-sectional study was conducted in a sample of 414 children ag...

UNLABELLED Statement of the problem: Infraoccluded primary molars can be managed in general dental practice but clinicians need to understand when intervention is necessary. PURPOSE OF THE STUDY To review the current literature on infraocclusion in primary molars, and to demonstrate diagnosis and management strategies for general dental practitioners. METHODS AND MATERIALS Current literatur...

Taurodontism is a relatively rare variance with a very low incidence in primary dentition and only a few cases have been reported in the literature. It stands a challenge when these teeth require pulp therapy. This case report illustrates the oral rehabilitation of multiple primary molars with taurodontism involving both the maxillary and mandibular arches, which is a rare occurrence.
