title: Alveolar bone height in infraoccluded primary teeth.
abstract: The purpose of this research is to describe the distance from the cemento enamel junction (CEJ) to the alveolar bone crest (ABC) of infra occluded primary molars and the adjacent and opposing teeth. Bitewing radiographs from 29 children (mean age 98.8 months; SD 21.2), who had infra occluded molars, were scanned and measured. The results of these measurements found that the means of the CEJ-ABC distances of the mesial and distal aspects of the infra occluded teeth were 0.78 mm (SD 0.3) and 0.94 mm (SD 0.32) respectively. Pearson correlation coefficient analysis revealed no significant correlation between the different measurements, except when comparing the measurements in the infra occluded tooth and those of the opposing tooth. It was concluded that the CEJ-ABC values for infra occluded primary molars are shorter than normal values. The CEJ-ABC distances of the opposing and adjacent teeth to the infra occluded tooth are within normal limits.
