Background: The inferior alveolar nerve (IAN) may be injured during extraction of the mandibular third molar,causing severe postoperative complications. Many methods have been described for evaluating the relativeposition between the mandibular third molar and the inferior alveolar canal (IAC) on panoramic radiography andcomputed tomography, but conventional radiography provides limited information on the proximity of thesetwo structures. The present study assessed the benefits of three-dimensional computed tomography (3D-CT)prior to surgical extraction of the mandibular third molar, to prevent IAN damage.
Methods: This retrospective study included 4917 extractions in 3555 patients who presented for extraction of themandibular third molars. The cases were classified into three groups, according to anatomical relationshipbetween the mandibular third molars and the IAC on panoramic radiography and whether 3D-CT was performed.
Symptoms of IAN damage were assessed using the touch-recognition test. Data were compared using thechi-square test and Fisher’s exact test.
Results: Among the 32 cases of IAN damage, 6 cases were included in group I (0.35 %, n = 1735 cases), 23 cases ingroup II (1.1 %, n = 2063 cases), and 3 cases in group III (0.27 %, n = 1119 cases). The chi-square test showed a significantdifference in the incidence of IAN damage between groups I and II. No significant difference was observed betweengroups I and III using Fisher’s exact test. In the 6 cases of IAN damage in group I, the mandibular third molar roots werelocated lingual relative to the IAC in 3 cases and middle relative to the IAC in 3 cases. The overlap was ≥2 mm in 3 of 6cases and 0?2 mm in the remaining 3 cases. The mean distance between the mandibular third molar and IAC was2.2 mm, the maximum distance 12 mm, and the minimum distance 0.5 mm. Greater than 80 % recovery was observedin 15 of 32 (46.8 %) cases of IAN damage.
Conclusions: 3D-CT may be a useful tool for assessing the three-dimensional anatomical relationship andproximity between the mandibular third molar and IAC in order to prevent IAN damage during extraction ofmandibular third molars.
