The authors conducted a study to quantify the reasons for restoring noncarious tooth defects (NCTDs) by dentists in The Dental Practice-Based Research Network (DPBRN) and to assess the tooth, patient and dentist characteristics associated with those reasons.
Data were collected by 178 DPBRN dentists regarding the placement of 1,301 consecutive restorations owing to NCTDs. Information gathered included the main clinical reason, other than dental caries, for restoration of previously unrestored permanent tooth surfaces; characteristics of patients who received treatment; dentists' and dental practices' characteristics; teeth and surfaces restored; and restorative materials used.
Dentists most often placed restorations to treat lesions caused by abrasion, abfraction or erosion (AAE) (46 percent) and tooth fracture (31 percent). Patients 41 years or older received restorations mainly because of AAE (P < .001). Premolars and anterior teeth were restored mostly owing to AAE; molars were restored mostly owing to tooth fracture (P < .001). Dentists used directly placed resin-based composite (RBC) largely to restore AAE lesions and fractured teeth (P < .001).
Among DPBRN practices, AAE and tooth fracture were the main reasons for restoring noncarious tooth surfaces. Pre-molars and anterior teeth of patients 41 years and older are most likely to receive restorations owing to AAE; molars are most likely to receive restorations owing to tooth fracture. Dentists restored both types of NCTDs most often with RBC.
作者开展了一项研究，以量化 The Dental Practice-Based Research Network（DPBRN）中牙医修复非龋性牙体缺损（NCTD）的原因，并评估与这些原因相关的牙齿、患者和牙医特征。
178 名 DPBRN 牙医收集了 1301 例连续 NCTD 修复的情况，记录了主要的临床原因（除龋齿外）、未修复的永久牙面修复原因、接受治疗的患者特征、牙医和牙科实践特征、修复的牙齿和牙面以及使用的修复材料。
牙医最常放置修复体以治疗磨损、微裂或侵蚀（AAE）（46%）和牙折（31%）引起的病变。41 岁及以上的患者因 AAE 接受修复治疗的比例最高（P<0.001）。前磨牙和前牙主要因 AAE 而被修复；磨牙主要因牙折而被修复（P<0.001）。牙医主要使用直接放置的树脂基复合材料（RBC）来修复 AAE 病变和折裂的牙齿（P<0.001）。
在 DPBRN 实践中，AAE 和牙折是修复非龋性牙面的主要原因。41 岁及以上患者的前磨牙和前牙最有可能因 AAE 而接受修复治疗；磨牙最有可能因牙折而接受修复治疗。牙医最常使用 RBC 修复这两种类型的 NCTD。
