Background: Combining antibiotics with non-surgical periodontal therapy has a beneficial impact in case of infection while its role for dental-related outcomes is still unclear.

Objectives: The current study's main objective was to evaluate the impact of adding adjuvant systemic and topical antimicrobial therapy to non-surgical periodontal therapy.

Material And Methods: A systematic literature search was accomplished and 1,093 study participants with periodontal diseases were recruited to the current study; 541 of them were treated with adjuvant systemic or topical antimicrobial agents and 552 with non-surgical interventions. The inclusion criteria of the current study took into account only randomized clinical trials.

Results: Adding systemic antibiotics to non-surgical intervention resulted in a significant enhancement regarding probing pocket depth reduction (PPD). Metronidazole/amoxicillin showed a significant impact on PPD and the clinical attachment level (CAL), while doxycycline showed no significant impact regarding CAL. Using topical antimicrobial agents showed a significant beneficial role in reducing PPD regarding doxycycline, while non-significant effects were seen with metronidazole.

Conclusion: Adding adjuvant systemic and topical antimicrobial agents to non-surgical periodontal therapy showed a beneficial impact regarding PPD and CAL (metronidazole/amoxicillin and doxycycline). In addition, using doxycycline as a topical agent showed a beneficial impact on the reduction of PPD.

We investigated the antimicrobial efficacy of seven essential oils from four plant families-Lamiaceae, Asteraceae, Zingiberaceae, and Poaceae-against microbes associated with dandruff. The antimicrobial effectiveness of these essential oils was assessed using paper disk agar diffusion and broth micro-dilution techniques. The results demonstrated that two of the essential oils significantly inhibited the growth of dandruff-associated microorganisms, with inhibition zones ranging from 5 ± 1.

Chronic consequences of diabetes that are most commonly encountered are diabetic foot ulcers (DFUs), driven by microbiota-immune system dyshomeostasis, eventually leading to delayed wound healing. Available therapies, such as systemic or topical administration of anti-inflammatory or antimicrobial agents, are limited due to antibiotic resistance and immune dysfunction. Herein, a hybrid hydrogel dressing is developed as the artificial bioadhesive barrier at wound sites to maintain microbial and immunological homeostasis locally and have potent anti-inflammatory effects.

One of the most important steps in preclinical drug discovery is to demonstrate the in vivo efficacy of potential leishmanicidal compounds and good characteristics at the level of parasite killing prior to initiating human clinical trials. This paper describes the use of dehydrothyrsiferol (DT), isolated from the red alga , in a pharmaceutical form supported on Sepigel, and the in vivo efficacy against a mouse model of cutaneous leishmaniasis. Studying the ultrastructural effect of DT was also carried out to verify the suspected damage at the cellular level and determine the severity of damages produced in the homeostasis of promastigotes.

This study investigates the development and comprehensive characterization of innovative thermoresponsive gels incorporating rosemary essential oil (RoEO) encapsulated in poly(lactic--glycolic acid) (PLGA) microparticles, with a focus on their potential applications in topical antimicrobial and wound healing therapies. RoEO, renowned for its robust antimicrobial, antioxidant, and wound-healing properties, was subjected to detailed chemical profiling using gas chromatography-mass spectrometry (GC-MS), which identified oxygenated monoterpenes as its dominant constituents. PLGA microparticles were synthesized through an optimized oil-in-water emulsion technique, ensuring high encapsulation efficiency and structural integrity.

Background: Thymoquinone (TQ) is found in the seeds of Nigella sativa. It has immunomodulatory, antibacterial, anti-inflammatory, antioxidant, astringent, antifungal, and antihistaminic properties, making it a highly valuable compound of interest. However, the use of it as a therapeutic drug is highly challenging because of its poor solubility, low bioavailability, and short-term stability.
