“…In the literature, we could find the presence of vital pulp tissue, fibroblasts, dentin, and predentine as well as a layer of odontoblast. This has been confirmed by several authors such as Vignudelli E et al [22] , Patel V et al [31] , and Goto et al [23] .…”

Introduction and importance Coronectomy represents a common procedure performed in oral surgery, mostly involving the lower wisdom teeth when the extraction presents a risk of injury to the inferior alveolar nerve (NAI). The surgical approach can be described as a coronal separation of the tooth and leaving the roots intact in the socket. The result is impressive with the disappearance of the symptomatology at first and especially the root migration, which occurs most frequently in the first 6 months. Cases series presentation We present a series of clinical cases of coronectomy involving the lower wisdom tooth which was performed by respecting the preoperative, perioperative, and postoperative measures and whose indications were established correctly. Discussion and conclusion Besides the previously mentioned indication, this procedure can be associated with other clinical situations such as dentigerous cysts. However, there are several circumstances in which coronectomy is contraindicated. According to our study, we can conclude that coronectomy of mandibular wisdom teeth represents a reassuring alternative to the preservation of NAI. Complications may occur but follow-up remains a key point in visualizing the progression of the roots away from the mandibular canal.

“…1,26 However, pulpitis in retained roots remains a rare complication if the biologic bases of the technique have been respected. 28 In conclusion, after coronectomy, satisfactory periodontal healing distal to the second molar and restoration of a normal periodontium were observed at 9 months postoperatively. This physiologic situation could be related to the long-term maintenance of the second molar.…”

“…Retained dental pulp was probably an important factor contributing to this phenomenon. It was reported that dental pulp would retain vitality after coronectomy [48,49]. Neurogenic inflammation after pulpectomy might lead to higher sensitivity to thermal stimulus [50].…”

Objectives This study aimed to quantitatively compare the somatosensory function changes of inferior alveolar nerve (IAN) after mandibular third molar extraction with a surgery protocol of coronectomy, as opposed to the conventional method. Materials and methods Patients with a lower third molar directly contacting IAN were recruited and assigned either to a test group (coronectomy group) or a control group (conventional extraction). A standardized quantitative sensory testing (QST) battery was performed for four times: one week before surgery and the second, seventh, and 28th days after surgery. Z-scores and the loss/gain coding system were applied for each participant. Results A total of 140 molars (test group: n = 91, control group: n = 49) were enrolled. The sensitivity of the mechanical detection threshold (MDT) and pressure pain threshold (PPT) significantly increased after surgery more than before surgery in both groups (P ≤ 0.001). After the surgery, the sensitivities of the cold detection threshold (CDT), cold pain threshold (CPT), and heat pain threshold (HPT) were significantly higher in the test group than in the control group (P ≤ 0.027). The risk of IANI was significantly larger (P = 0.041) in the test group than in the control group. Conclusions QST was a sensitive way to detect somatosensory abnormalities even with no subjective complaint caused by surgery. Coronectomy had less influence on IAN function than conventional total extraction. Clinical relevance The somatosensory function changes after mandibular third molar extraction were quantitatively studied, and coronectomy was proved a reliable alternation to reduce IAN injury rate.
