Coronectomy of mandibular third molars with dental pathology: a prospective cohort study of 121 molars.
Purpose: Coronectomy is a valuable treatment proven safe for non-pathological mandibular third molars with an increased risk of inferior alveolar nerve injury. Coronectomy may also be useful for mandibular third molars with dentigerous cysts and caries, but this is not commonly performed due to the lack of well-designed, evidence-based studies. Here, we aim to investigate the safety of coronectomy for mandibular third molars with caries and dentigerous cysts.
Methods: One hundred fifteen patients with an impacted mandibular third molar with a dentigerous cyst or caries underwent coronectomy or complete removal and received follow-up with clinical and radiographical examinations. We statistically compared the presence of postoperative complications after coronectomy versus complete removal.
Results: Data from 121 molars were available for analysis. The results revealed no significant difference in the occurrence of postoperative complications (including persistent pain, inferior alveolar nerve injury, infection, alveolar osteitis, excessive bleeding, and the need for retreatment) between coronectomy and complete removal. Additionally, the incidence of postoperative complications was not related to any analyzed patient- or molar-related factors, including age, gender, health status, smoking, caries, dentigerous cyst extent, and impaction degree.
Conclusion: For pathological impacted mandibular third molars with dentigerous cysts and caries, coronectomy exhibited both short-term and long-term safety, showing no significant difference in postoperative complications compared to total removal. Our results suggest that coronectomy can be indicated for pathological mandibular third molars with proximity to the inferior alveolar nerve.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
