“…H 2 S had the lowest score, which was 0.27 ± 0.39 ng/10 ml for PS group and 0.33 ± 0.34 ng/10 ml for EOS group. This showed that oral malodor may arise if there is no oral activity done in 4 hrs [12]. That condition was proved by the mean of CH 3 SH >0.5 ng/10 ml and the mean of (CH 3 ) 2 S >0.2 ng/10 ml, which is the threshold by which an odor can be smelled by the human sense of smell, according to Tonzetich criteria.…”

“…This was consistent with the Acceptance Program Guideline released by the American Dental Association at the Council on Scientific Affairs 2003. According to Tonzetich, the effect from oral activity will disappear in 3 hrs [12]. Following the initial measurement of oral malodor parameters, participants were requested to consume one type of oral refresher strip (randomized as either EOS or PS).…”

Objective: The aim of this study was to determine the efficacy of an oral freshener strip containing five types of essential oils on oral malodor. Methods:This study was a clinical trial using cross-over, randomized-double-blind, and placebo-controlled trial design with 15 male participants. The measured parameters were tongue coating, organoleptic score, and volatile sulfur compounds (VSCs) score. Results:After the essential oil strip dissolved in the oral cavity, there was no significant reduction in tongue coating, but there was significant reduction (p<0.05) in the organoleptic score until 60 minutes after dissolved and VSCs until 30 minutes after dissolved. Conclusion:Essential oil strips are more effective than placebo strips in reducing oral malodor.

Abstract. The subgingival microbial ecology is complex, and little is known regarding its bacteria species composition in healthy Chinese individuals. This study aimed to identify the subgingival microbiota from 6 healthy Chinese subjects. Subgingival samples from 6 volunteers were collected, the 16S rRNA gene was amplified using broad-range bacterial primers, and clone libraries were constructed. For the initial 2,439 sequences analyzed, 383 species-level operational taxonomic units (SLOTUs) belonging to seven phyla were identified, estimated as 51% [95% confidence interval (CI) 44-55] of the SLOTUs in this ecosystem. Most (85%) of the bacterial sequences, falling into 228 types of species, corresponded to known and cultivated species. However, 146 (6%) sequences, comprising 104 phylotypes, had <97% similarity to prior database sequences. Ten bacterial genera were conserved among all 6 individuals, comprising 2,000 (82%) of the 2,439 clones analyzed. Ten species were noted in all of the 6 subjects, comprising 1,435 (58.8%) of the 2,439 clones. Streptococcus infantis was the species most frequently cloned. Furthermore, certain species which may participate in the pathogenesis of periodontal disease were present in the 6 subjects. Although the initial subgingival plaque community of each subject was unique in terms of diversity and composition, 10 common key species were found in the 6 Chinese individuals. These ten species of bacteria in the human subgingival plaque in the 6 healthy individuals may be key species which, to some extent, affect periodontal health. Destruction of these key species in subgingival bacteria may break the microbiota balance and may easily lead to over-breeding conditions resulting in pathogenic oral disease.

The Role of Green Tea in Oral Health – A Review

Tea is the most widely consumed and a popular beverage in the world. Over the past decade, molecular components of teas and their health benefits on humans have received increasing attention from researchers. Functional foods are foods with positive health benefits that extend beyond their normal nutritional value. They interrupt the functions of the body and help in the management of specific health conditions and preventing pathologic changes. One such nature's gift is green tea. Green tea, a leading beverage in the Far East for the past thousand years, is an important source of polyphenol antioxidants. (EGCG) epigallocatechin 3 gallate, a polyphenol, constitute the most interesting components in green tea leaves. There is an increasing interest on the health benefits of green tea in the field of oral health. Green tea is renowned for its antioxidant, anti-cariogenic, anti inflammatory and antimicrobial properties. This traditional beverage is also used in the management of chronic systemic diseases including carcinoma. Recent studies has emphasized that in addition to the microbial activity, the host immuno-inflammatory reactions destroy the oral tissues to a greater extent. In such cases green tea is considered to be a natural preventive and curative agent. There is a growing search of evidence for understanding the beneficial role of green tea and its polyphenols in oral health. Numerous studies have shown the beneficial effects on the regular intake of green tea in maintaining oral health. Even though studies demonstrate the health effects of green tea polyphenols, more clinical and biological studies to support guidelines for green tea intake as part of prevention and treatment of specific oral pathologies are needed.
