Effectiveness of probiotic lozenges and Chlorhexidine mouthwash on plaque index, salivary pH, and count among school children in Makkah, Saudi Arabia.

Purpose: To compare the effect of the probiotic lozenges and chlorhexidine (CHX) mouthwash on plaque index (PI) , salivary pH and Streptococcus mutans (S. mutans) 3 count among groups of Saudi children.

Methods: A total of 54 participants aged 8-12 years were randomly allocated into three groups, 18 children in each group.

Identification and characterization of a novel antimicrobial peptide compound produced by strain isolated from oral microflora.

In recent years, the decreased efficacy of existing antibiotics toward management of emergent drug-resistant strains has necessitated the search for novel antibiotics from natural products. In this regard, sp is well known for producing variety of secondary metabolites of potential use. Therefore, we performed an investigation to isolate and identify sp from oral cavity for production of novel antimicrobial compounds.
