Background: Mouth breathing is a type of habitual adaptation of breathing to fulfill the needs of oxygen. This habit could alter the biological oral condition and development of children. The altered condition of the oral environment could affect oral hygiene and cause oral malodor. Organoleptic is using human sense as a measurement to assess severity of oral malodor. Enterococcus faecalis is the transient bacteria of the oral cavity particularly found in the root canal of the failed endodontic treatment teeth. Based on previous studies, Enterococcus faecalis existence in children is unknown.

Purpose: To analyze the existence of Enterococcus faecalis antigen in salivary and tooth plaque samples of children based on organoleptic and OHI-S (Oral Hygiene Index-Simplified) score.

Methods: Salivary and tooth plaque sample of children age 8-11 were tested with ELISA (Enzyme-linked immunosorbent assay) technique and divided into several groups. The grouping was done based on the organoleptic and OHI-S score of subjects. Data analyzed by comparing scores between children who have a tendency toward mouth breathing with those who breathe with nose based on their organoleptic and OHI-S score.

Result: Mostly, there is no significant difference between groups who tend mouth breathing with those who breathe with nose based on organoleptic and OHI-S score. However, in one of the tests, there is significant difference within groups who breathe with nose based on organoleptic score. The antigen amount of Enterococcus faecalis was found higher in tooth plaque rather than in saliva.

Conclusion: The amount of Enterococcus faecalis antigen is higher in tooth plaque and there is a tendency that the amount of Enterococcus faecalis is influenced by the OHI-S score."
