Scaling and root planing is the basic treatment modality for periodontal disease. Mechanical treatment is limited by physical impediments and biochemical considerations. Antimicrobial agents may be used as an adjunct to overcome limitations of mechanical therapy.
A case-control study was carried out on 30 patients suffering from chronic periodontitis. In Group A only scaling and root planing was carried out whereas in Group B tetracycline fibers were used along with scaling and root planing.
Tetracycline fibers as an adjunct to scaling and root planing was found to be more effective in reducing inflammation. The number of sites with bleeding on probing were 12 in Group A as compared to four in Group B after 30 days. The mean decrease in probing depth was more in Group B than Group A after 30 and 90 days. General linear model showed that decrease in probing depth was statistically significant with both mechanical therapy as well as adjunctive use of tetracycline fibers.
Local drug delivery with tetracycline fiber is an effective and simple non surgical method to improve periodontal health which can be practiced even by a general dental practitioner.
龈上洁治术和根面平整术是牙周病的基本治疗方式。机械治疗受到物理阻碍和生化因素的限制。抗菌药物可作为辅助手段来克服机械治疗的局限性。
对30例慢性牙周炎患者进行了一项病例对照研究。A组仅进行龈上洁治术和根面平整术,而B组在龈上洁治术和根面平整术的同时使用四环素纤维。
发现四环素纤维作为龈上洁治术和根面平整术的辅助手段在减轻炎症方面更有效。30天后,A组探诊出血部位有12个,而B组为4个。30天和90天后,B组探诊深度的平均减少量比A组更多。一般线性模型显示,机械治疗以及四环素纤维的辅助使用在探诊深度减少方面具有统计学意义。
四环素纤维局部给药是一种有效且简单的非手术方法,可改善牙周健康,甚至普通牙科医生也可实施。
