摘要
目的 :研究由牙周非手术治疗引起的牙髓和根面牙本质敏感 (RDS)的改变。方法 :2 0例患者共 30 6个患中到重度牙周炎的牙齿 ,接受口腔卫生宣教 (OH) 2周以及洁刮治和根面平整 (S/RP) 1、2、4和 8周后 ,用电活力测试仪测定牙髓的敏感性 ,用探诊和吹气两种方法 ,并用VAS量表评估根面敏感性。结果 :在整个实验期内 ,牙髓活力无显著性改变 (P >0 .0 5 )。在 2周的观察期内 ,经良好的菌斑控制后 ,RDS由 4 .18降至 2 .4 5(P <0 .0 1) ,但经S/RP后 ,根面敏感显著增加 ,治疗后 1周 ,根面敏感最为严重 ,达 6 .6 8(P <0 .0 1) ,在随后 3次的复诊中 ,根面敏感度逐渐下降 ,至 8周时 ,与治疗前已无显著性差异 (P >0 .0 5 )。结论 :良好的菌斑控制会减少RDS的发生 ;牙周非手术治疗对牙髓的敏感性无影响 。
AIM:To study the effects of supragingival , subgingival scaling and root planning(S/RP) on pulp and root dentine sensitivity(RDS).METHODS:Alternations in pulp and RDS were measured in 306 teeth of 20 patients with moderate to advanced periodontal disease 1,2 week after oral hygiene (OH) and 1,2,4,8 week after S/RP.The pulp sensitivity was assessed with an electric pulp test.RDS was evaluated with two forms of controlled stimulations(probe and air-blast) as graded by a 10 cm visual analogue scale(VAS).RESULTS:Over time, no changes in pulp sensitivity were found( P >0.05).After two weeks plaque control, RDS reduced significantly from 4.18 to 2.45 ( P <0.01) .However,a clinically significant increase in RDS was observed after S/RP, and reached the peak(6.68) after 1 w( P <0.01). During the subsequent 3 times of follow-up, RDS decreased gradually. At 8 weeks following S/RP, no statistically significant difference in relation to pre-S/RP data was observed( P >0.05).CONCLUSION:Meticulous plaque control results in a decreased RDS; non-surgical periodontal treatment has no effect on pulp vitality, but it might cause a more or less transient occurrence of RDS.
