Effectiveness of 1064 Diode Laser Therapy for Treatment of Periodontitis
Objectives: This study investigated the effectiveness of scaling & root planing and 1064 XLASE (Fotona LLC, Dallas,TX) diode laser therapy (SRP+LASER) as compared to scaling & root planing only (SRP-ONLY) in treating moderate-to-advanced (Stage II-to-III) chronic periodontitis.
Methods: Twenty-two subjects met all inclusion/exclusion criteria and completed the protocol. Subjects had at least one control (SRP-ONLY) and one experimental (SRP+LASER) site randomly selected but several subjects had more than one tooth involved per site area depending on the number of adjacent teeth per site. The treatment sites varied in size from a single tooth up to four adjacent teeth. Forty-two teeth were treated as SRP-ONLY sites and 64 teeth as SRP+LASER sites. Clinical crown lengths (CCLs), probing depths (PD) and bleeding on probing (BOP) were recorded by a blinded examiner pre-treatment (T1) and at three month intervals up to final post-treatment (T2) at 12-to-18 months. Cone beam computer tomographs (CBCT) were taken at T1 and T2 to evaluate treatment effects on bone levels. Repeated measures ANOVA and t-tests were used for analysis.
Results: There were no statistically significant differences in pre-treatment/T1 variables between the SRP-ONLY and SRP+LASER groups. This included CCLs, PD, BOP and changes in interproximal bone height as measured on the T1 CBCT scan. Both treatment groups showed reductions in PD and BOP with little change in CCLs; however, there were no statistically significant differences in mean changes (T2-T1) between the SRP-ONLY and SRP+LASER groups for these variables (p>0.05). There was a significant increase in bone fill (T2-T1) for the SRP+LASER (p=0.002) group when compared to the SRP-ONLY group (TABLE).
Conclusions: The SRP-ONLY and SRP+LASER therapies produced reductions in PD and a marked reduction in BOP. CCLs were relatively stable, and minimal gingival recession was observed for both treatment groups. Bony defects showed statistically significant bone fill (p=0.002) with the SRP+LASER group over the SRP-ONLY group.
