目的?探讨提高上颌第一恒磨牙近颊第二根管(MB2)发现率的临床方法.方法?临床随即选取需要治疗的上颌第一磨牙120颗.分为两组:第1组66例,用头灯放大镜寻找MB2并记录其发现率;第2组55颗牙,在常规光源下寻找MB2并记录发生率,并与第1组MB2发现率相比较.结果?第一组头灯放大镜实验组MB2发现率为83.08%,第二组常规光源对照组MB2发现率38.18%,两组比较P<0.01.结论?使用头灯放大镜在寻找上颌第一恒磨牙MB2时明显优于常规光源,与口腔显微镜相比,经济实惠、适合临床推广.

Objective?To?find?whether?there?was?any?difference?between?the?occurrence?of?mesiobuccal?2nd?canal?(MB2)?and?its?detection?rate?with?Headlight?loupe.?Method 120 extracted maxillary first molars were divided into 2 groups. Group 1 added up to 65,Headlight loupe was used to look for MB2 ,?and?the?detection?rate?of?MB2?was?calculated.?Group?2?added?up?to?55,being?looked?for?MB2?under?White?Light,?occurrence?of?MB2?was?calculated?and?compared?to?the?detection?rate.?Result Detection rate with Headlight loupe was 83.08%, Detection rate with White light was 38.18%. Statistically significant discrepancy?was?found?between?the?occurrences?and?detection?rate?(=10.12,P?<?0.05).?Conclusion?Detection?rate?of?MB2?could?be?greatly?improved?by?the?use?of?Headlight?loupe.
