Objectives: The aim of this study was to evaluate and compare the antibacterial efficacy of licorice gel and tetracycline gel against Aggregatibacter actinomycetemcomitans , Porphyromonas gingivalis and Prevotella intermedia ., Methods: An indigenously prepared 50 μL licorice and tetracycline gel was subjected to antibacterial sensitivity test (thrice) against Aa, Pg, Pi by agar well diffusion method using Brain Heart Infusion media. Colonies of Aa, Pg, Pi was transferred into broth and incubated at 37 °C for 24 h and diameter of inhibition zone was measured., Results: The drug release profile of licorice gel at six regular intervals was higher when compared to tetracycline. MIC of licorice gel (50 μg/mL) against Aa (14 mg), Pg (7 mg), Pi (7 mg) respectively. The diameter of inhibition zone of licorice gel was significant against Aa when compared to tetracycline gel. However, tetracycline gel exhibited significant diameter of inhibition zone against Pg and Pi when compared to licorice gel. There was a statistical significance difference between licorice and tetracycline gel against Aa (p=0.043*), Pg (p=0.037*), Pi (p=0.046*) while assessing antibacterial sensitivity test., Conclusions: Licorice gel has anti-inflammatory and anti-microbial properties which can act against periodontal pathogens and can be considered in treating periodontal disease at low concentrations. Therefore, it can be used as an adjunctive local drug delivery agent to non-surgical periodontal therapy (NSPT) in treating periodontal disease., (© 2024 Walter de Gruyter GmbH, Berlin/Boston.)

Objectives: Periodontal disease is a chronic, infectious gum disease, which eventually leads to tooth loss, adversely affecting quality of life (QoL). Most of the research in this area focuses on evaluating clinical parameters rather than patient-based outcomes. Currently, these parameters are gaining importance along with treatment outcomes of chronic diseases and QoL. This study evaluates the impact of periodontal disease and its treatment on oral health-related quality of life (OHRQoL)., Methods: We recruited 90 participants who were divided into two groups. One was the test group (n = 45) that underwent non-surgical periodontal therapy (NSPT) followed by periodontal flap surgery (SurgPT). Second was the control group (n = 45) that underwent only NSPT. Clinical parameters, plaque index, gingival index, periodontal/probing pocket depth (PPD), clinical attachment level (CAL), and mobility were recorded. An OHRQoL questionnaire was used to assess the functional, physical, social, and psychological domains at baseline, three, and six months., Results: The mean PPD in the test group was 6.9 ± 0.38, 3.2 ± 0.36, 3.5 ± 0.5, and 5.8 ± 0.67, 3.13 ± 0.21, 3.73 ± 0.45 in the NSPT group at baseline, 3, and 6 months, respectively. The mean CAL in the SurgPT group was 7.07 ± 0.41, 3.56 ± 0.27, 3.74 ± 0.30, and 6.08 ± 0.16, 4.02 ± 0.17, 4.16 ± 0.19 in the NSPT group at baseline, 3, and 6 months, respectively. Both treatments resulted in reduction in all clinical parameters and were statistically significant in the SurgPT group ( p  < 0.001). Oral Health Impact Profile scores substantially decreased in the SurgPT group (mean difference-25.0) compared to the NSPT group (mean difference-5.0) ( p -0.001)., Conclusions: In this study, NSPT and SurgPT had a positive impact on OHRQoL by improving clinical parameters, but SurgPT had substantially better outcomes in terms of improved QoL., (© 2021 Taibah University.
