Periodontal sites of shallow initial probing depth often seem to lose probing attachment following various types of periodontal therapy, including nonsurgical therapy. The susceptibility to this treatment-associated probing attachment loss may conceivably be related to gingival architecture as well as to the inflammatory status of the tissues. This study was designed to study the relationship of buccolingual gingival thickness and bleeding on probing in shallow buccal sites (less than or equal to 3.5 mm probing depth) to loss of probing attachment following nonsurgical therapy. 3 months following treatment consisting of oral hygiene instruction and supra- and subgingival debridement, thin (less than or equal to 1.5 mm), initially non-bleeding sites displayed a mean loss of probing attachment of 0.3 mm. Thick (greater than or equal to 2.0 mm), non-bleeding sites displayed a less noticeable mean loss of probing attachment, whereas bleeding sites of both categories of gingival thickness showed a tendency towards gains in probing attachment levels. It may be concluded that the mean loss in probing attachment levels, commonly seen for shallow sites post-therapy, may be primarily due to the changes in shallow, thin healthy areas.
在包括非手术治疗在内的各种牙周治疗后，初始探诊深度较浅的牙周部位似乎常常会丧失探诊附着。这种与治疗相关的探诊附着丧失的易感性可能与牙龈结构以及组织的炎症状态有关。本研究旨在探讨颊舌侧牙龈厚度和浅颊侧部位（探诊深度小于或等于3.5mm）探诊出血与非手术治疗后探诊附着丧失之间的关系。在进行口腔卫生指导以及龈上和龈下刮治治疗3个月后，薄型（小于或等于1.5mm）、最初不出血的部位探诊附着平均丧失0.3mm。厚型（大于或等于2.0mm）、不出血的部位探诊附着丧失不太明显，而两类牙龈厚度的出血部位探诊附着水平有增加的趋势。可以得出结论，治疗后浅部位常见的探诊附着水平平均丧失可能主要是由于浅、薄健康区域的变化。
