“…27 However, smooth root surfaces are not a perquisite for a successful SRP. 28,29 Smooth root surfaces at the gingival margin are advantageous because the odds of dental plaque accumulation on smooth surfaces are less than that on rough surfaces and the efficacy of plaque removal from the smooth surfaces is higher than that from rough surfaces. Some studies 30,31 have shown that surface roughness due to subgingival SRP significantly increases subgingival microbial colonization.…”

J Lasers Med Sci. 2017;8(2):66-71. doi:10.15171/jlms.2017.12. IntroductionPeriodontal diseases are among the most common infectious diseases caused by the accumulation of bacterial plaque on tooth surfaces. Periodontitis can result in soft and hard tissue destruction and eventual tooth loss. Scaling and root planning with hand instruments, sonic and ultrasonic devices and air abrasion are performed for treatment of periodontal diseases.1 Nonsurgical periodontal debridement is performed aiming to efficiently eliminate plaque and calculus without damaging root surfaces. Manual instruments and ultrasonic devices have long been used for scaling and root planing (SRP) with successful results. 2Dental lasers were recently introduced to increase the efficacy of conventional SRP, and many studies have evaluated their efficacy in enhancing the biocompatibility and attachment of fibroblasts to root surfaces. 3 The efficacy of erbium-doped yttrium aluminum garnet (Er:YAG) laser The efficacy of erbium-doped yttrium aluminum garnet (Er:YAG) laser for root debridement in comparison with curettes has been the subject of many recent investigations. Considering the possibility of chemical and ultra-structural changes in root surfaces following laser irradiation, this study sought to assess the effects of scaling and root planing (SRP) with curettes and Er:YAG laser on chemical properties and ultrastructure of root surfaces using spectroscopy and scanning electron microscopy (SEM). Methods: In this in vitro experimental study, extracted sound human single-rooted teeth (n = 50) were randomly scaled using manual curettes alone or in conjunction with Er:YAG laser at 100 and 150 mJ/pulse output energies. The weight percentages of carbon, oxygen, phosphorous and calcium remaining on the root surfaces were calculated using spectroscopy and the surface morphology of specimens was assessed under SEM. Data were analyzed using one-way analysis of variance (ANOVA). Results: No significant differences (P > 0.05) were noted in the mean carbon, oxygen, phosphorous and calcium weight percentages on root surfaces following SRP using manual curettes with and without laser irradiation at both output energies. Laser irradiation after SRP with curettes yielded rougher surfaces compared to the use of curettes alone. Conclusion: Although laser irradiation yielded rougher surfaces, root surfaces were not significantly different in terms of chemical composition following SRP using manual curettes with and without Er:YAG laser irradiation. Er:YAG laser can be safely used as an adjunct to curettes for SRP.

Background:The study aimed at comparing the effectiveness of rotary instruments with hand instruments in non-surgical treatment of chronic periodontitis.Materials and Methods:Thirty-eight patients with chronic periodontitis, enrolled to this randomized, controlled clinical trial, were divided into two groups. Patients in the control group received scaling and root planing with hand instruments, whereas patients in the test group received treatment with rotary instruments. Clinical assessment by plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level was made prior to and at 6 months after treatment. Differences in the clinical parameters were analyzed using the Wilcoxon signed rank test and Mann–Whitney U test.Results:Both treatments resulted in a significant improvement in all clinical recordings, but no differences in any of the investigated parameters were observed at baseline between the two groups.Conclusion:Non-surgical periodontal therapy with the tested rotary instruments may lead to clinical improvements comparable to those obtained with conventional hand instruments.

“…Although the roughness of the root surface does not seem to interfere with periodontal healing the diagnosis of remaining subgingival calculus on a rough root surface might be hampered [23]. Consequently an instrumentation method which creates rough dentine surfaces carries the risk of overinstrumentation on the one hand side and remaining undiagnosed calculus on the other hand.…”

Some laboratory studies have evaluated the oscillation mode of ultrasonic scalers. None of them recorded its influence on calculus removal and quantified dental hard tissue loss. This study aimed to compare the performance of a magnetostrictive ultrasonic instrument at different power settings in vitro in relation to the tip oscillation activity. The oscillation activity of the straight Slimline® insert in the Cavitron® ultrasonic scaling device was analyzed at five different power settings with the help of two laser vibrometers. The performance of this instrument was tested on 60 roots of human single-rooted teeth. Twelve roots each were randomly assigned to be instrumented at a given power setting. Every root was instrumented for 120 s at a standardized instrumentation force of 0.1 ± 0.05 N. In addition, another 30 periodontally involved roots with subgingival calculus were instrumented accordingly to assess the calculus removal potential. The surface characteristics after instrumentation were analyzed under scanning electron microscope. The instrumentation at minimum power setting resulted in an mean increase of the root surface roughness of 0.18 ± 0.28 compared to 0.51 ± 0.48 at maximum power setting (P = 0.0327). The loss of dental hard tissue amounted to 11.37 ± 3.64 at minimum compared to 23.37 ± 15.76 at maximum power (P = 0.0010). The higher the power setting, the more calculus was removed. The values of the latter ranged between 4.04 ± 1.87 and 11.26 ± 4.66 mm² of cleaned dentin surface area (P = 0.0065). At lower power settings, a more favorable relation between cleaning ability, loss of dentine, and surface roughness was found. cleaned dentin surface area (P=0.0065). At lower power settings, a more favourable relation between cleaning ability, loss of dentine and surface roughness was found.
