A SEM investigation on pulpal-periodontal connections in primary teeth.

The ideal goal of pulpotomy procedure in a primary tooth is to maintain space length, preserve masticatory function, and remove infection and chronic inflammation from the oral cavity. From a population of 150 patients between the ages of four and seven years, we collected a sample of 30 primary (nine maxillary and twenty-one mandibular) molars used in this investigation. The aim was to observe the presence of accessory channels on the pulpal floor; they were found in twenty-one of the thirty teeth examined. The scanning electron microscope proved to be an excellent means of evaluating the pulpal floor, where failure of pulp treatment often has its cause.
