Relationship analysis of the lingual nerve to different molar gingival margin distance
Anatomy Research(2013)
Abstract
Objective To investigate the lingual nerve to different molar gingival margin distance,for patients with a relevant operation treatment to provide reliable clinical evidence,as far as possible to avoid the occurrence of postoperative patients with lingual nerve damage,improve patients' quality of life.Methods In our hospital,from 2000 to 2012 between the collected adult head specimens in 20 randomly selected patients were dissected,all specimens have antiseptic fixing measure,use of special measuring tool for specimen of the left lingual nerve,the right lingual nerve and first,two or three molar gingival margin distance measurements were performed,recorded and analyzed statistically measured results,draw a conclusion.Results The left lingual nerve and the right lingual nerve were first,two or three molar gingival margin horizontal distance,vertical distance and angle of 45 degrees with close distance,and P 0.05,the left lingual nerve and lingual nerve apart right first molar gingival margin without statistical significance.Conclusion In patients undergoing mandibular lingual bone crest trimming operation or impacted wisdom tooth extraction treatment,should be based on human tongue neuroanatomical knowledge,as well as the lingual nerve to different molar gingival margin distance range,avoid as far as possible for patients with lingual nerve damage,so as to effectively prevent the occurrence of postoperative patients with temporary or permanent abandon sensory loss complications,improve patients' quality of life.
