The purpose of this study was to morphologically evaluate, by means of scanning electron microscopy, the effects of Er:YAG laser on the treatment of root surfaces submitted to scaling and root planing with conventional periodontal instruments. Eighteen root surfaces (n = 18), which had been previously scaled and planed, were assigned to 3 groups (n = 6). The control Group (G1) received no further treatment; Group 2 (G2) was irradiated with Er:YAG laser (2.94 mum), with 47 mJ/10 Hz, in a focused mode with air/water spray during 15 s and with 0.57 J/cm² of fluency per pulse; Group 3 (G 3) was irradiated with Er:YAG laser (2.94 mum), with 83 mJ/10 Hz, in a focused mode with air/water spray during 15 s and with 1.03 J/cm² of fluency per pulse. We concluded that the parameters adopted for Group 3 removed the smear layer from the root surface, exposing the dentinal tubules. Although no fissures, cracks or carbonized areas were observed, an irregular surface was produced by Er:YAG laser irradiation. Thus, the biocompatibility of the irradiated root surface, within the periodontal healing process, must be assessed.

This study used scanning electron microscopy (SEM) to evaluate the morphology and adhesion of blood components on root surfaces instrumented by curettes, piezoelectric ultrasonic scaler and Er,Cr:YSGG laser. One hundred samples from 25 teeth were divided into 5 groups: 1) Curettes; 2) Piezoelectric ultrasonic scaler; 3) Curettes plus piezoelectric ultrasonic scaler; 4) Er,Cr:YSGG laser; 5) Curettes plus Er,Cr:YSGG laser. Ten samples from each group were used for analysis of root morphology and the other 10 were used for analysis of adhesion of blood components on root surface. The results were analyzed statistically by the Kruskall-Wallis and Mann-Whitney tests with a significance level of 5%. The group treated with curettes showed smoother surfaces when compared to the groups were instrumented with piezoelectric ultrasonic scaler and the Er,Cr:YSGG laser. The surfaces instrumented with piezoelectric ultrasonic scaler and Er,Cr:YSGG laser, alone or in combination with hand scaling and root planing, did not differ significantly (p>0.05) among themselves. No statistically significant differences (p>0.05) among groups were found as to the adhesion of blood components on root surface. Ultrasonic instrumentation and Er,Cr:YSGG irradiation produced rougher root surfaces than the use of curettes, but there were no differences among treatments with respect to the adhesion of blood components.

Background: The goal of the present study was to compare the efficacy of two piezoelectric scalers with hand instrumentation in calculus removal, loss of tooth substance and roughness created on root surface. Methods: 90 freshly extracted non-carious, non-restored single rooted teeth with hopeless periodontal prognosis were included in the study. They were divided into three groups of 30 teeth each i.e. Group 1,Group 2 and Group 3 where instrumentation was done using two piezoelectric scalers- Piezoelectric scaler A & Piezoelectric scaler B and Gracey curette respectively. Specimens were subjected to Scanning Electron Microscopy (SEM) & Profilometric analysis to evaluate the root surface roughness created by these three instruments. Results: Statistically significant difference was observed in Remaining calculus index (RCI) in the three experimental groups with hand instrument being least effective in removing calculus when compared to the piezoelectric scalers(p≤0.05). There was significant difference in mean Loss of tooth substance index(LTSI) and Roughness loss of tooth substance index (RLTSI) scores when compared in the three groups (p value =0.002). Both SEM and profilometric analysis showed that Piezoelectric scaler A and Piezoelectric scaler B caused less root surface roughness compared to hand instruments. Conclusion: The findings of the present study suggest that scaling and root planing using both piezoelectric scalers and hand instruments were effective in mechanical debridement of the root surface. However, piezoelectric instruments gave smoother root surface than hand instruments and were also more efficient in calculus removal.
