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.
