Analysis of pulp chamber of primary maxillary second molars using 3D micro-CT system: an in vitro study

Authors:

ABSTRACT

Aim

The aim of this study was to determine the positional relationship between the crown contour and the pulp chamber as
well as the morphological characteristics of the pulp chamber using micro-CT in order to plan, in restorations of deciduous maxillary
second molars, reconstructions with a volumetric rendering programme.

Methods

Study Design: In total 16
deciduous maxillary second molar teeth (8 from boys, 8 from girls) were used. The positional relationship between crown contour and
pulp chamber was three-dimensionally observed by micro-CT. Differences in sex, dentin thickness and pulp volumes were evaluated
using chi-square and paired t-tests. Differences were considered significant when P < 0.05.

Results

Dentin thickness was found to
be 2.8 mm 0.2, mesiobuccally 3.15 mm 0.2 distobuccally 3.8 0.3, which was statistically significant
(p0.05). The pulp volume for boys was 77 mm 4, for girls 64 mm 5, with a statistical significance
(p0.05). CONCLUSIONS: General differences could play a role when planning a treatment for a child; however for both genders it
should be noted that mesiobuccal pulp horn is most likely to get exposed during cavity preparation.
