“…The LNI was found to be directly influenced by age in this study which is in accordance with few previous studies [17,18]. Root completion, sclerosed bone, ankylosed tooth, presence of infection and loss of tissue elasticity are some of the age related changes of the jaw bones [2].…”

“…Root completion, sclerosed bone, ankylosed tooth, presence of infection and loss of tissue elasticity are some of the age related changes of the jaw bones [2]. Therefore the age of the patient is a factor directly related to the surgical morbidity associated with removal of lower impacted third molars [17,18]. With an increase in age there is an increase in health risk factors which may influence postoperative recovery [2].…”

Background and Objectives The purpose of this prospective study was to evaluate the incidence and various risk factors influencing the sensory deficit in case of lingual nerve injury (LNI) in individuals whose impacted mandibular third molars are surgically removed under local anesthesia. Materials and Methods The study was based on the data collected prospectively from a random group of 100 patients who underwent surgical removal of bony impacted lower third molar in a dental hospital. Details of the patient, reason for extraction, type of impaction, method of surgery and signs and symptoms of nerve injury are recorded. Neurosensory testing was done to evaluate the LNI at 1 week, 1 months, 3 months and 6 months interval.Comparison was carried out using Chi square test. For all tests a P \ 0.05 was considered significant. Results The incidence of LNI was 4 % and of temporary in nature which recovered well within 6 months postoperatively. The age of the patient above 26 years, lingual flap retraction, depth of impaction (red line C10 mm) and duration of surgery above 30 min were the significant factors for causing LNI. Conclusions The age of the patient, depth of impaction, lingual flap retraction and longer duration of surgery are significant risk factors for LNI during mandibular third molar surgery. Greater care should be taken to avoid the morbidity and patients should be informed well ahead about the probable complications.

“…the alveolar inferior nerve (IAN), the buccal nerve and the lingual nerve, are seen as the most severe postoperative complications after removal of a mandibular third molar. [3][4][5][6] In a radiographic image of the third molar region, only the course of the IAN may be estimated since the mandibular canal, within which the nerve is situated, is usually visible. The course of the other two essential nerves in the region are not seen in radiographs.…”

A radiographic examination of mandibular third molars is meant to support the surgeon in establishing a treatment plan. For years panoramic (PAN) imaging has been the first choice method; however, where an overprojection is observed between the third molar and the mandibular canal and when specific signs suggest a close contact between the molar and the canal, CBCT may be indicated. The present review provides an evaluation of the efficacy of CBCT for assessment of mandibular third molars using a six-tiered hierarchical model by Fryback and Thornbury in 1991. Levels 1-3 include studies on low evidence levels mainly regarding the technical capabilities of a radiographic method and the diagnostic accuracy of the related images. Levels 4-6 include studies on a higher level of evidence and assess the diagnostic impact of a radiographic method on the treatment of the patient in addition to the outcome for the patient and society including cost calculations. Only very few high-evidence studies on the efficacy of CBCT for radiographic examination of mandibular third molars exist and, in conclusion, periapical or PAN examination is sufficient in most cases before removal of mandibular third molars. However, CBCT may be suggested when one or more signs for a close contact between the tooth and the canal are present in the two-dimensional image-if it is believed that CBCT will change the treatment or the treatment outcome for the patient. Further research on high-evidence levels is needed. Dentomaxillofacial Radiology (

“…One of the post-operative complications associated with this procedure is damage to the inferior alveolar nerve (IAN), which can result in transient or permanent neurosensory impairments affecting the lower lip and chin. The risk of temporary IAN injury following mandibular third molar removal is reported at between 0.26% and 8.4%, and permanent IAN injury at between 0.1% and 0.9% [1][2][3][4] , and is associated with a significant negative impact on quality of life 5 .…”
