After scaling and root planning (SRP), healing induces the formation of a junctional long epithelium rather than a new connective attachment. We hypothesize that the placement of a periodontal dressing will be able to prevent detachment of coagulum inducing proper healing and improving periodontal parameters.
This split-mouth study included 30 patients with periodontitis with ages ranging from 35 to 70 years. Probing pocket depth (PD), probing attachment level (PAL), bleeding on probing index (BoP) and plaque index (PI) were assessed before and after therapy. The group of patients received SRP in a span of 24 h. Then, a periodontal dressing was applied on the test side and it was removed after 1 week.
The difference between PD values at baseline and after therapy was 1.6 ± 0.6 mm. The difference in PAL (ΔPAL) measurement was 1.4 ± 0.4. Test group: there was a greater PD reduction, this being 2.4 ± 0.6 mm on average. The difference in PAL was 2.5 ± 0.4 mm.
Our results clearly suggest that the use of a periodontal dressing improves the periodontal parameters after an SRP procedure. This is probably due to clot stabilization and prevention of bacterial colonization during wound healing.
在进行牙周刮治和根面平整(SRP)后,愈合会诱导形成连接的长上皮组织,而不是新的结缔组织附着。我们假设牙周敷料的放置能够防止血凝块脱落,从而促进适当的愈合并改善牙周参数。
这项分口研究包括 30 名年龄在 35 至 70 岁之间的牙周炎患者。在治疗前后评估探诊袋深度(PD)、探诊附着水平(PAL)、探诊出血指数(BoP)和菌斑指数(PI)。患者组在 24 小时内接受 SRP。然后,在试验侧应用牙周敷料,1 周后去除。
在基线和治疗后 PD 值的差异为 1.6 ± 0.6mm。PAL(ΔPAL)测量的差异为 1.4 ± 0.4mm。试验组:PD 平均减少 2.4 ± 0.6mm。PAL 的差异为 2.5 ± 0.4mm。
我们的结果清楚地表明,在 SRP 手术后使用牙周敷料可改善牙周参数。这可能是由于在伤口愈合过程中稳定了血凝块并防止了细菌定植。
