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.

摘要

目的

本研究的目的是测量与乳牙上颌和下颌第一、二磨牙髓腔形态相关的关键解剖标志。

方法

在标准化条件下，使用毫米级X射线格栅为42名受试者拍摄咬合翼片。使用Image J分析软件对153颗乳牙（44颗上颌第一磨牙、49颗上颌第二磨牙、30颗下颌第一磨牙和30颗下颌第二磨牙）进行所需解剖标志的分析。对每项测量的数据进行均值、标准差和变异系数分析。使用单因素方差分析，随后进行Tukey事后HSD检验比较均值测量结果。
