Journal: Pediatric Dentistry
Date: 2015
Major Topic: Primary dental anatomy; pulp chamber, primary molars
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.
Type of Article: Cohort Study - Quantitative
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 4 mm
·       The distance between pulpal floor to furcation was approximately 1.7 mm
·       The average height of the pulp chamber was observed to be in the range of 2 to 3 mm.

CONCLUSION:

The key measurements involved in access cavity preparation were consistent across the different types of primary molars. Based on this study’s results, the following conclusions can be made:
1.     The key measurements related to the dimensions of the pulp chamber involved in access cavity preparation were consistent across different types of primary molars.
2.     The buccal cusp tip to pulp chamber ceiling distance (i.e., depth of endodontic access) showed a low coefficient of variance and was, on average, four mm for primary molars.
3.     The buccal cusp tip to furcation distance (i.e., safety margin during access preparation) also showed a low coefficient of variance and was, on average, 7.8 mm for primary first molars and 9.3 mm for primary second molars.
