Assessment of the role of green tea use on oral health
Background and Aim: Streptococcus mutans (S. mutans) is the main etiological bacteria present in the oral cavity that leads to dental caries. Different preceding studies have recognized green tea to have anti-inflammatory, antiviral, antifungal, antioxidant, protein-denaturing, anti-mutagenic, anti-diabetic, anticarcinogenic, and antibacterial characteristics. The aim of our study is to investigate the effects of rinsing with 2% green tea solution for 5 min. on S.mutans count in both saliva and plaque and Gingival Bleeding Index (GBI).
