BACKGROUND

Regarding the fact that halitosis has social and personal aspects which can lead to social embarrassment and consequently low self-esteem and self-confidence in subjects suffering from the problem, especially children, its proper treatment is an important issue.

OBJECTIVES

The aim of this study was to evaluate the effect of metronidazole as a nonspecific antimicrobial agent in the treatment of halitosis in children.

MATERIALS AND

METHODS

In this study, 2-10 years old children with oral halitosis were enrolled. Children without H. pylori infection and parasitic infection were randomized in two interventional and control groups. Metronidazole was given 5mg/kg/day for one week. Information regarding the demographic characteristics of studied population and halitosis (duration and time of day with more halitosis and its severity) before and after intervention was recorded using a questionnaire.

RESULTS

77 children with halitosis were studied in two interventional (40 children) and control (37 children) groups. There was no significant difference between two groups before intervention. After intervention, halitosis improvement rate - according to the reports of mothers of studied children - was higher significantly in intervention group (P < 0.05).

CONCLUSIONS

The results support the effectiveness of metronidazole in the treatment of halitosis. Moreover, it supports recent findings regarding the participation of specific bacteria specially unculturable ones in the pathogenesis of the disease.
