Aim: Study of the causes that may contribute to complications during and after tooth extraction to justify treatment and prevention measures. materials and methods: A retrospective analysis of the content of ambulatory cards and protocols of operations of 168 patients for the period from 2016 to 2018 and evaluation of the results of personal work for 2018-2020 related to surgical interventions in 134 patients which removed the third lower molars. Results: According to the retrospective material, damage to the inferior alveolar nerve was found in 5.9% of cases, lingual nerve – in 3.3% of cases, the prevalence of alveolitis with simple removal was 16.3% of cases, at difficult and surgical removal – 3.9% of cases. The application of our proposed treatment and prevention complex allowed to reduce their rates to 3.1%, 2.3%, 8.0% and 3.8% of cases, respectively. Risk factors for complications have been identified. Conclusions: when planning the method of surgical removal of third lower molars it is necessary to take into account the probability of its intimate location in relation to inferior alveolar nerve and lingual nerve. The presence of focus of destruction with signs of acute or exacerbation of chronic inflammation in the periodontal bone tissue of the causative tooth is a risk factor for alveolitis and an indication for the appointment of treatment and prevention in the preoperative period, even with simple removal.

Background: The aim of this prospective study was to determine the incidences of inferior alveolar nerve and lingual nerve deficit following surgical removal of impacted mandibular third molars and to evaluate the risk factors responsible for these postoperative neurosensory deficits.Methods: A total of 80 patients who reported to department of oral and maxillofacial surgery, Meenakshi Ammal Dental College, Chennai, Tamil Nadu, India requiring surgical removal of impacted mandibular third molar were included in this cross-sectional study. Standard surgical procedure was performed. All patients were reassessed one week post-surgery. Subjectively reported altered sensations were recorded and objective assessments were performed with light touch test, two-point discrimination threshold and pin-pick pain threshold. The collected data was analyzed using the chi square test to find out any clinical relevance.Results: There was no inferior alveolar nerve related neurosensory deficits and 6 (7.5%) resulted in lingual nerve related neurosensory deficits. The incidence of LN deficit for mesioangular, horizontal, distoangular was 1.3%, 3.8% and 2.5% respectively. Type of impaction assumed a mild statistical significance (p = 0.050).Conclusions: This study highlights the importance of careful preoperative clinical and radiographic assessment of patients where third molar surgery is planned. The surgical technique of third molar removal is also likely to have great impact on the outcome.

AIM: To evaluate a new technique for surgical removal of deeply impacted mandibular third molars (DIMTM), using computer-guided cutting guide to maintain inferior alveolar nerve (IAN) integrity and the covering buccal bone. PATIENTS AND METHODS: Eighteen cases indicated for removal of DIMTM. Cone-beam Computed Tomography (CBCTs) used to determine the tooth’s relation to the IAN. Computer-guided software used for fabrication of surgical cutting guide stent to expose the impacted tooth and repositioning of bone after odontectomy without fixation. Clinical assessment included a neurosensory deficit of IAN, pain using a visual analogue scale (VAS), facial swelling, and maximal mouth opening (MMO). CBCTs were taken immediately and six months postoperatively to evaluate position and healing of bone. RESULTS: None of the patients showed a permanent neurological deficit of IAN while all patients showed normal parameters of pain, facial swelling and MMO. CONCLUSION: this technique has shown the accurate determination of the bony window cuts with subsequent preservation of IAN and external oblique ridge.

To assess the nerve injury (inferior alveolar nerve) after surgical removal of mandibular third molars under local anesthesia. Study Design: Observational study. Setting: Oral & Maxillofacial Surgery Department LUMHS Jamshoro/Hyderabad. Period: From 11th November 2015 to 10th May 2016. Material & Methods: This study consisted of one hundred patients. Inclusion criteria’s were patients with impacted mandibular third molar, patient’s age from 18 to 45years and irrespective of gender. Exclusion criteria were patients younger than 18yrs of age of above 45 years, patients having neurological disorders, medically compromised patients, patients receiving radiotherapy or chemotherapy, patients with known allergy to local anesthesia, patients having pathology due to mandibular third molars, patients radiographicaly root is very near to inferior dental canal. Results: Out of 100 patients incorporated in this research 66 were male (66%) and 34 female (34%). The mean age was 29+3.20 years. Common indication of extraction were recurrent pericoronitis  52(52%) cases followed by deep caries/ pulpitis in 28(28%)  cases, orthodontic reason in 11(11%) cases and caries to adjacent tooth in 9(9%) cases. Third molar impaction according to winter’s classification were Mesioangular in 54(54%) cases followed by Horizontal in 26(26%) cases and Vertical in 11(11%). Radiographic showed Narrowing of root in 21% cases and narrowing of inferior dental (ID) canal 20% cases, followed by diversion of ID canal in 16 % cases, deflection of root 14 % cases and darkening of root in 11% cases. After surgical removal of mandibular third molar, the inferior alveolar nerve injury was observed in 6(6%) cases. Conclusion: We conclude that inferior alveolar nerve paresthesia occurs in 6% after surgical removal of mandibular third molars.

Inferior Alveolar Nerve Injury

Coronectomy is a valuable technique in the management of symptomatic mandibular third molars at high risk of inferior alveolar nerve injury. When applied appropriately, the technique may reduce the incidence of inferior alveolar nerve injury in comparison to full surgical removal. Currently, no definitive guidelines exist on when to opt for coronectomy versus full surgical removal, and therefore significant variation in clinical practice exists. This article summarizes the surgical stages involved in the coronectomy procedure, reviews the indications and hazards of the technique, and finally provides suggested guidelines to assist the practitioner in the decision-making process of when to opt for coronectomy versus full surgical removal in the management of symptomatic mandibular third molars. CPD/Clinical Relevance: To review the coronectomy technique and highlight potential hazards with inappropriate application of the technique.

Mandibular Third Molars

Background: Mandibular third molars are the most commonly impacted teeth and frequently associated with various pathologies including infection, traumatic, inflammatory and cystic lesions necessitating their surgical removal. To avoid complications, clinical and radiographic evaluation of impacted teeth is essential to provide information about tooth anatomy, position and condition of the surrounding bone. Aim: To evaluate impacted mandibular third molars (IMTM) with the help of panoramic radiographs for the type of impaction, available third molar space, level of eruption, and relation to the inferior alveolar nerve (IAN). Materials and Methods: Total 600 patients were selected and were divided into three groups; group I (18-27 years), group II (28-37 years), and group III (>38 years). Digital OPG were traced and evaluated for angulations, third molar space, level of eruption, and relation of third molar roots to IAN canal. The observations were subjected to statistical analysis using Chi-square test. Results: Out of 600 samples, 306 (51%) were males and 294 (49%) were females. Out of 1079 third molar sites, mesioangular impaction (40.22%) was the most common. Class II relation (84.24%) for third molar space and level A of eruption (45.69%) were most frequent. In true relation, interruption of the white line of the IAN canal (20.85%) was the most frequent relation of the IMTM roots to the IAN canal and others (false/no relation) was the most common in all relations. Conclusion: Panoramic radiography is a relatively safe, reliable, inexpensive, and readily accessible technique for preoperative evaluation of IMTM and their relation to IAN canal.
