Effect of systemic antibiotic and probiotic therapies as adjuvant treatments of subgingival instrumentation for periodontitis: a randomized controlled clinical study

Abstract

Effect of systemic antibiotic and probiotic therapies as adjuvant treatments of subgingival instrumentation for periodontitis: a randomized controlled clinical study* Objective: This study assessed the efficacy of two adjunct therapies (antibiotic and probiotic) for periodontal treatment based on clinical and immunological parameters in patients with Stage II and III Grade B periodontitis. Methodology: 45 patients were randomly allocated into three groups: control group (CG); antibiotic group (GAtb), in which 500 mg amoxicillin + 400 mg metronidazole were used; and probiotic group (GProb), for which Lactobacillus reuteri was used. Patients received medications after undergoing periodontal debridement. Clinical and immunological parameters were assessed at baseline, 30 days, and 90 days. Results: All therapies reduced bleeding on probing (BoP) in the evaluated periods, and the GAtb had a greater reduction at 90 days (p=0.03). The GProb group showed better results for plaque index (PI) and gingival recession (GR) compared to the GAtb at 90 days (p=0.0014; p=0.006). The area of inflammation (PISA Index) significantly decreased in all therapies in the evaluated periods. Therapies had no significant differences regarding moderate pockets. The GAtb had a greater reduction in probing depth (PD) for deep pockets (p=0.03) at 90 days and in the number of deep pocket sites at 30 days (p=0.04). The occurrence of adverse effects was commonly reported in the GAtb as a percentage per patient. The GAtb had a significant reduction in the concentration of interleukins IL-1β and IL-8 and an increase in IL-10 and TNF-α. The CG had a reduction in IL-6 and IL-1 β, whereas in the GProb there was no difference. Conclusion: After three months, none of the adjuvant therapies provided any additional benefit for subgingival instrumentation.

Evaluation of the Effect of Topically Applied Probiotics on Interleukin-10 and Osteoprotegerin as an Adjunctive Treatment of Stage І and П Grade A Periodontitis Cases

“…These results corresponds with findings of different studies showed significant improvement in PI and GI after probiotic supplementation (28,31,32) . Another study indicated that a daily consumption of a probiotic milk reduces the effects of plaque-induced gingival inflammation in patients with a higher plaque score (33,(34)(35)(36)(37) . While another recent study suggested that the use of probiotics seemed not to be beneficial for prevention of plaque accumulation as it could be affected by reduced oral hygiene (38) .The use of probiotic tablets containing L. plantarum, L. brevis and P. acidilactici did not lead to significant changes in mean GI otherwise, a significant reduction occurred in the number of sites with higher GI and severely inflamed in addition to a significant microbiological impact have been promoted only in the test group (39) .…”

O Uso De Antibióticos Como Adjuvante No Tratamento Da Periodontite

“…No entanto, 5 revisões destacaram a ausência de evidências suficientes para determinar tanto a eficácia da antibioticoterapia adjuvante, como o melhor momento para o seu início (FRITOLI et al 2015;ABDALLAOUI-MAAN, BOUZIANE, 2020;KHATTRI et al, 2020;LUCHIAN et al, 2021;RAMOS et al, 2022).…”

“…Apesar dos benefícios sugeridos dos antibióticos sistêmicos, eles expõem o indivíduo a riscos potenciais, como o desenvolvimento de resistência microbiana, o surgimento de infecções fúngicas oportunistas, reações alérgicas e outros efeitos colaterais. Em dois dos artigos selecionados, foi observada uma prevalência significativa de eventos adversos leves (KHATTRI et al, 2020;RAMOS et al, 2022).…”

The use of oral probiotics in non-surgical periodontal therapy: Literature Review

“…These amounts are equivalent to 15% of the world population [6] . The use of probiotics has been proposed as an adjunct to periodontal therapy due to the origin of the disease based on dental plaque formed by bacteria [7] . Probiotics are defined as living organisms, bacteria that do not have any pathogenic characteristics.…”
