Abstract:Background: Dimension and location of pulp chamber are important during access cavity preparation. It allows clinician in instruments selection, orientation and depth of cutting during the process. Analysis of these has been done in preoperative intraoral periapical radiograph that gives two-dimensional image. The radiograph has been blamed now and then for the inaccurate results and iatrogenic damage occurred due to the inaccurate results. Cone-Beam Computed Tomography (CBCT) provides three-dimensional imag… Show more
“…Studies done in the past have evaluated morphological landmarks of pulp chambers in both molars and premolars using two-dimensional radiographs. 3,4,6,[12][13][14] Research on the Indian population by Vijaykumar et al 15 and Selvakumar et al 12 although utilized spiral CT however their studies were conducted on primary, not permanent teeth. Bovino et al evaluated the pulp chamber thickness in the primary teeth of the Brazilian population by CBCT.…”
The aim of this study was to evaluate and compare the anatomical landmarks of maxillary and mandibular molar pulp chambers and evaluate bilateral symmetry between contralateral molars using CBCT.CBCT scans of 200 molars from 157 patients were selected for the study. A total of nine measurements - A (Distance from the cusp tip to the roof of the pulp chamber) B (Distance from the cusp tip to the floor of the pulp chamber) C (Distance from the cusp tip to the furcation) D (Distance from the floor of the pulp chamber to the furcation) E (Distance from the roof of the pulp chamber to the furcation) F (Height of pulp chamber) A1(Distance from the central fossa to the roof of the pulp chamber) B1 (Distance from central fossa till the floor of pulp chamber) C1 (Distance from central fossa to furcation) were done. Statistical analysis was done using the ANOVA and Post hoc tests and statistical significance was set at p<0.05. Significant differences in maxillary and mandibular molars were noted in the measurements of- D, E, B and C1. Bilateral symmetry was also observed between the pairs of maxillary and mandibular molars.Maxillary first and second molars do not differ much from each other. However, mandibular first and second molars differed in various anatomic parameters from each other. Contralateral molars (maxillary and mandibular) pulp cavities, in general, exhibit matching symmetry in terms of their morphological and anatomical landmarks.
