Coronectomy for lower third molar surgery


This review of coronectomy versus extraction of third molars in patients at increased risk of inferior alveolar nerve (IAN) injuries included 42 observational studies. The findings indicate lower a reduction in the odds of IAN sensory loss in favour of coronectomy and an increase in the odds of surgical reintervention.

Articaine local anaesthesia and the risk of hyperaesthesia in third molar surgery


This review of the risk of hyperaesthesia with articaine compared with other local anaesthetics in lower alveolar nerve block for lower third molar removal included 13 studies.The findings suggest that the use of articaine does not increase the risk of hyperaesthesia.

Panoramic radiography for predicting inferior alveolar nerve injury after third molar surgery


This review of panoramic radiography for IAN injury prediction after third molar surgery included 8 studies calculating key diagnostic data fro the 7 classical used signs. Values were to low to rule out post-operative damage before surgery but some siigns could rule in risk of injury.

Prognosis of nerve injuries caused by over-extruded endodontic materials


27 case reports and 1 case series were identified for this review of nerve damage due to over-extruded endodontic materials providing very low quality evidence for management of the problem.

Does panoramic radiography predict nerve injury after third molar extraction?


This review included 9 studies assessing the predictive value of panoramic radiography on inferior alveolar nerve (IAN) injury after third molar extraction. Results suggest that darkening of the root had a high specificity in predicting IAN injury.

Inferior alveolar nerve injury following bilateral sagittal split osteotomy lacks standardised assessment procedures and reporting says review


As this review looks as potential harms from bilateral sagittal split osteotomy a wide range of study designs were included. However, the majority relied on subjective assessment of Inferior alveolar nerve injury so a standardised assessment and reporting procedure is needed.

Nerve repositioning for implant placement: neurosensory complications common


This review of complications following inferior alveolar nerve repositioning techniques included 24 studies the majority at high risk of bias. Initial sensory disturbance was highest with lateralisation technique but lower at end of follow up periods than transposition approach.

The lingual and inferior alveolar nerves are potential at risk of damage during some oral and maxillofacial surgery procedures. Fortunately the majority are temporary, with resolution taking place within 8 weeks.  Injuries of 6 moths or greater are considered permanent and a range of techniques have used.   The aim of this review was to evaluate [read the full story…]

Significant association between several risk factors and Inferior alveolar nerve problems after third molar extraction

The incidence reported in the literature ranges from 0.4-8.4%third molars and in some instances the damage can be permanent. The aim of this case-control study was to investigate the specific risk factors for neurosensory deficits of inferior alveolar nerve (IAN) after third molar extraction. The cases consisted of patients showing neurosensory deficits of the lower [read the full story…]
