The Location and Incidence of Patent Accessory Pulpal Canals in Permanent Molars with Periodontal Lesion by Using Micro-Computed Tomography

Objective: In this study, the event of patent accessory pulpal canals situated in periodontal pockets has been resolved to utilize the micro-CT method. Methods: Fifty-seven extracted permanent human teeth were utilized to examine the commonness, location, and diameter of the patent accessory canals that are opening outside toward the periodontal pocket by utilizing micro-CT and high-resolution desktop. Results: Through 57 molars 6 (10.25%) were accessible with patent accessory, canals inside furcation area, of root, 49 (85%) were accessible with patent accessory canals inside the mesial and distal buccal root, and 28 (49.1%) were accessible with patent accessory, canals inside the palatal/lingual root. A measurably critical variety was found alongside the nearness of patent accessory trench in various roots and pocket depth at a similar region of the nearness waterway just as the nearness of these canals and connection misfortune in this region. Conclusions: Progression of periodontal pocket might be responsible for opening accessory canal and cause pulp pathosis, making successful periodontal therapy difficult.

Incidence of patent furcal accessory canals in permanent molars of a Turkish population.

To determine the incidence of patent furcal accessory canals in permanent molars of a Turkish population. Two-hundred extracted teeth consisting of 50 maxillary first molars, 50 maxillary second molars, 50 mandibular first molars and 50 mandibular second molars from Turkish patients attending the Oral Surgery Department of the Faculty of Dentistry, Istanbul University, Istanbul, Turkey, were included in the study. After preparation of access cavities and removal of pulp tissue, the teeth were stored in 5.25% sodium hypochlorite for 1 h. Following double-sealing of the access cavities, all tooth surfaces except the furcation regions were covered with nail varnish. The teeth were stored in 0.5% basic fuchsin for 1 week. The teeth were sectioned at the cemento-enamel junction and the presence of patent furcal canals was established by examining the pulp chamber floor with a stereomicroscope (10x) to determine staining. Patent furcal accessory canals were detected in 24% of maxillary first molars, 16% of maxillary second molars, 24% of mandibular first molars, and 20% of mandibular second molars. No statistically significant differences were found between the tooth types. In a Turkish population, the incidence of patent furcal accessory canals on the pulp chamber floor of maxillary and mandibular first and second molars ranged between 16 and 24%.
