The aim of this in vitro study was to determine the morphological measurements of the pulp chamber and also to establish the relationship of the cemento-enamel junction (CEJ) to the roof of the pulp chamber of the maxillary first molars in an Indian population. One hundred extracted human maxillary first molars were used. Each molar tooth was radiographed by radio visiography (RVG). Measurements were made by using the grid option in RVG. The results (mean SD; in mm) were as follows: distance from floor of the pulp chamber to the furcation = 2.7 0.63; distance from roof of the pulp chamber to the furcation = 5.34 0.9; distance from tip of the palatal cusp to the furcation = 11.58 1.01; distance from the tip of the palatal cusp to the floor of the pulp chamber = 8.86 0.68; distance from the tip of the palatal cusp to the roof of the pulp chamber = 6.2 0.66; height of the pulp chamber = 2.62 0.61. The results of these measurements revealed that the morphological measurements of the maxillary first molars in the Indian population were similar to that reported by previous studies; the roof of the pulp chamber was found at the CEJ in 96% of the specimens.
