Abstract:

Mouth ulcers, a common oral mucosal disorder, can cause discomfort and interfere with daily activities. Natural remedies like guava leaves extract have shown promising potential in managing such conditions due to their anti-inflammatory and antimicrobial properties. This study aimed to formulate and evaluate an aqueous gel of guava leaves extract for the treatment of mouth ulcers. The guava leaves extract was prepared using a maceration method and incorporated into a gelbase consisting of Carbopol 934P. Various formulations were prepared with different concentrations of guava leaves extract to

Abstract:

Background: Streptococcus mutans is a major contributor to the formation of dental plaque and the initiation of caries. Orthodontic appliances, particularly removable ones, can create favorable conditions for S. mutans colonization, increasing the risk of caries and other oral health issues. Chlorhexidine is a commonly used antimicrobial agent in dentistry, but it can have side effects like tooth staining and altered taste. Guava leaf extract has shown promising antibacterial properties due to its rich content of flavonoids, tannins, and other bioactive compounds. This study aimed to compare t
