Cervical abrasion and some factors related to oral hygiene habits and periodontal health were investigated in 250 subjects aged 21-60 yr. The subjects were considered dentally aware since they had visited their dentist on a regular basis over the past several years. A high occurrence rate of cervical abrasion was noted with 85% of subjects exhibiting at least one superficial lesion. Manifest or deep lesions, although less common, were present in 22% of subjects. Both prevalence and severity increased with age. The severity expressed as the mean number of lesions was 7.3 for the total sample. It increased significantly with calculus index, frequency of periodontal pockets, and reduction of the alveolar bone height. No significant associations were observed between abrasion and oral hygiene factors. It is concluded that cervical abrasion, although most likely related to toothbrushing, may not be synonymous with periodontal health. Ineffective toothbrushing may not only fail to prevent disease but may also cause cervical abrasion.
对250名年龄在21至60岁之间的受试者进行了宫颈磨损以及与口腔卫生习惯和牙周健康相关的一些因素的调查。这些受试者被认为具有牙齿保健意识，因为他们在过去几年中定期去看牙医。宫颈磨损的发生率很高，85%的受试者至少有一个浅表病变。明显或深部病变虽然不太常见，但在22%的受试者中存在。患病率和严重程度均随年龄增长而增加。以病变平均数表示的严重程度在总样本中为7.3。它随着牙石指数、牙周袋频率和牙槽骨高度的降低而显著增加。在磨损与口腔卫生因素之间未观察到显著关联。得出的结论是，宫颈磨损虽然很可能与刷牙有关，但可能与牙周健康不是同义词。无效刷牙不仅可能无法预防疾病，还可能导致宫颈磨损。
