Root Surface Smoothness or Roughness in Periodontal Treatment: A Clinical Study

Abstract

Twelve patients with localized advanced periodontitis were selected for this study. The 18 teeth used were divided into experimental and control groups. In both groups the loss of attachment and pocket depth were measured and modified Widman flap surgery was performed. In the experimental group, after root planing, a number of shallow horizontal grooves were made on the root surface to roughen them. Four months after surgery the same measurements were made. The results indicated that in both groups the pocket reduction and the gain of attachment were statistically significant. The differences between the two groups, as far as pocket reduction and gain of attachment are concerned, were not significant.

Sonic and ultrasonic scalers in periodontal treatment: a review

“…Direct comparison of piezoelectric and magnetostrictive scalers ( in vitro ), regarding calculus removal and tooth surface roughness following instrumentation, has shown that the piezoelectric system was more efficient for calculus removal, but left the instrumented tooth surface rougher (30). These results have been in conflict with results from another study which found that root surfaces instrumented by piezoelectric scalers were smoother than those following instrumentation with magnetostrictive scalers (16, 27, 31). Studies into working parameters and roughness showed that higher instrument power setting resulted in higher mean and maximum surface roughness at both low and high lateral forces.…”

“…But the roughness values after treatment with oscillating sonic and ultrasonic inserts do not differ from each other; there was also no difference in roughness compared to the control surface. But most studies showed that smoother surfaces are obtained with curettes than with an air scaler or ultrasonic instruments (23) and ultrasonic scalers tended to increase roughness (24–27). The roughness of the root surface after scaling procedure is a considerable factor for maintenance, because it has also been reported that bacterial plaque adheres easily to the rough root surfaces after treatment with an ultrasonic scaler (18, 28, 29).…”

The Influence of Anatomic and Iatrogenic Root Surface Characteristics on Bacterial Colonization and Periodontal Destruction: A Review

“…Other reports have failed to observe an effect of root surface roughness on subgingival plaque formation or gingival inflammation. [75][76] Incomplete scaling in deep pockets may have masked a potential effect of differences in root surface roughness.75 In another clinical trial,76 no negative effect of shallow, horizontal root surface grooves upon periodontal healing was demonstrated. A closer examination of these data, however, indicates a tendency of higher attachment gain in the smooth root surface group (43%) than in the rough surface group (39%).…”

Aspectos clínicos, microbiológicos e tratamento periodontal em pacientes fumantes portadores de doença periodontal crônica: revisão da literatura

“…Para Khatiblou e Ghodssi, 35 essa rugosidade pode não influenciar no sucesso do tratamento, visto que, a redução na profundidade observada foi semelhante entre os dentes com e sem rugosidade.…”
