Abstract

PURPOSE: The purpose of this study was to measure key anatomic landmarks related to pulp chamber morphology in primary maxillary and mandibular first and second molars.

METHODS: Bitewing radiographs of 42 subjects were taken under standardized conditions using a millimeter X-ray grid. One hundred fifty-three primary molars (44 maxillary first molars, 49 maxillary second molars, 30 mandibular first molars, and 30 mandibular second molars) were analyzed for the required anatomic landmarks using Image J Analysis Software. The data were analyzed in terms of mean, standard deviation, and coefficient of variance for each measurement. Mean measurements were compared using one-way analysis of variance followed by Tukey's post-hoc HSD test.

RESULTS: The distance between cusp tip to pulp chamber ceiling was approximately four mm, the distance between pulpal floor to furcation was approximately 1.7 mm, and the average height of the pulp chamber was observed to be in the range of two to three mm.

CONCLUSION: The key measurements involved in access cavity preparation were consistent across the different types of primary molars.
