Dental microscope as a useful tool to detect foramina in the furcation and pulp chamber oor of permanent teeth
Journal Title: Stomatos - Year 2017, Vol 23, Issue 44
Abstract
This study assessed the in uence of evaluation methods in the occurrence of foramina in the pulp chamber oor and in the furcation area of molars with complete and incomplete root formation. Methodology: A sample of 360 sound mandibular permanent molars was selected and prepared. A single experienced operator evaluated the whole sample using two methods: clinical inspection (with the naked eye) and dental microscope (at 30x magni cation). Chi- square test was used to compare the detection of foramina between evaluation methods in both regions (p<0.05). Results: A limited number of specimens with foramina in the pulp chamber oor was observed, while there were more teeth with foramina in the furcation area, according both methods. The dental microscope identi ed signi cantly more molars with foramina in the furcation (p=0.000) and in the pulp chamber oor (p=0.031) than the clinical inspection. Conclusions: The presence of foramina in the furcation region is substantially greater than in the pulp chamber oor, regardless of the evaluation method. The presence of foramina is not in uenced by the rhizogenesis stage. The dental microscope is an excellent tool to view dental anatomical details.
