Abstract:

BACKGROUND: Clinical methods for pulpitis always devitalize pulp vitality and destroy a great quantity of tooth tissues, resulting in tooth fracture. However, studies have indicated that pulp tissue has self-defense and self-recovery potentiality. Therefore, it is appropriate to preserve vital pulp considerging biology.
OBJECTIVE: To investigate feasibility of drilling pinhole on pulp chamber in digital radiographs.
METHODS: A total of 60 clear radiographs from VixWin PRO were selected, and pulp chamber height and pulp chamber width were measured (pulp chamber height: distance from roof of pulp chamber to midpoint of bilateral socket ridge line in the anterior teeth and premolars, or distance from midpoint of roof of pulp chamber to midpoint of floor of pulp chamber in the molars; pulp chamber width: distance from mesiwall to distal wall of pulp chamber. Height and width of pulp chamber was measured with electronic gage in VixWin PRO. Mean was calculated respectively. The pulp chambers were observed whether they were contained two transfusion needles.
RESULTS AND CONCLUSION: The smallest mean height was 3.43 mm, width 0.80 mm in front teeth and premolars, and height 1.80 mm, width 2.35 mm in molars. The pulp chambers could contain two transfusion needles (No. 5.5). It is feasible to drill two pinholes on pulp chamber.
