Comparações clínica e radiográfica de duas técnicas de aplicação do laser de baixa potência como adjuvante à terapia periodontal básica em pacientes com periodontite - um ensaio clínico controlado e randomizado. Orientadora: Dra. Ana Rafaela Luz de Aquino Martins. 2023. 60f. Dissertação (Mestrado em Ciências Odontológicas) - Centro de Ciências da Saúde, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/58173Aim: To assess and compare two techniques of low-level laser application - transgingival (LLLTT) and intrasulcular (LLLTI) - used in Photobiomodulation as an adjunct to BPT in patients with periodontitis. Methods: This is a randomized, split-mouth, double-blind clinical trial where, from each patient, 3 diseased periodontal sites in different quadrants were selected for one of three treatment groups: SRP group (control group), SRP + LLLTT group (test 1), and SRP + LLLTI group (test 2). Low-level laser therapy in the test groups was performed at three time points, 48 hours, 7 and 14 days after completing full-mouth SRP. Clinical parameters of probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were assessed before treatment (T0), and at 3 months (T1) and 6 months (T2). Additionally, standardized periapical radiographs were used to measure and compare radiographic bone density 6 months after treatment completion. Repeated-measures ANOVA was conducted for quantitative variables, and the chi-square test was used for the categorical variable, with a significance level of p < 0.05 and 95% confidence intervals. Results: Statistically significant reductions in PD (p < 0.001) and CAL (p < 0.001) were observed in all three treatment groups at 3 and 6 months follow-up compared to baseline, with no significant differences between the groups. No significant differences were found in bleeding on probing at 3 and 6 months and in radiographic bone density at 6 months of follow-up. Conclusion: The results indicated that, compared to isolated basic periodontal therapy (TPB), adjunctive photobiomodulation did not provide additional benefits, regardless of the laser application technique used.Acesso AbertoPeriodontiteTerapia com luz de baixa intensidadeFotobiomodulaçãoTratamento periodontal não-cirúrgicomasterThesisCNPQ::CIENCIAS DA SAUDE::ODONTOLOGIA
