Abstract

Background and Aim: One of the most important aspects in oral and maxillofacial surgery is the healing process after periapical surgery during apicotomy, transplantation or pathological surgeries. Past studies with the vascular supply to surgically mobilized dentoalveolar segments, apicotomized transplanted teeth and root resected teeth in periodontal disease, have mentioned occasional encounters with vital root resection and have noted varying degrees of pulpal response to this insult. The purpose of this investigation was to observe the pulpal and periapical responses of dog dental tissues to intentional apical vital root amputation over six months postoperative period.Methods & Materials: Four adult German - Canadian dogs were used in this experimental study. One root of multirooted teeth in left quadrant of each jaw Weresurgically transected and mandibular quadrants for 12; 13,24 and 25 weeks following surgery were obtained after the animals were sacrificed by formalin perfusion of the left and right carotids. The tissue blocks were prepared by routine histological methods. Fisher exact test were used for data analysis.Results: The results demonstrated a disruption of the normal pulpal architecture, with initial pulpal degeneration and subsequent early replacement by the periodontal ligament tissue. An intermediate cemental lining of the root canal occurred in all specimens. There was fat tissue in the apical part of the root in some specimens. Pulpal regeneration were seen in 75% of upper molars and 25% of lower molars. Resorption were took place only in two specimens (12.5%). Severe hyperemia were seen in 62.5% of all specimens.Conclusion: The pulp of multirooted teeth, remain vital after transaction of apical part of the root in dogs.
