Background. Due to the increase in the prevalence of asthma, especially in childhood, oral health problemsarising from the use of asthma medications have become a major health concern. Inhaled corticosteroids arewidely used since they are the cornerstone of asthma management. This study aimed to investigate the effects ofinhaled corticosteroids on oral health and various factors regarding active ingredients in inhalers, inhaler-spacerdevice use, rinsing the mouth after administration of inhaler, oral hygiene practices and parents’ education ondental caries susceptibility in young children with asthma.Methods. Children with asthma who were treated with inhaled corticosteroids for at least 6 months wereincluded in the study. A questionnaire related to demographic characteristics and oral health practices ofchildren was conducted with parents and the children were examined using a dental mirror and probe underdental unit lighting after air-drying the teeth.Results. Oral health status was evaluated in 115 children, 54 (42-66) months old, 61% male and 39% femalewith determination of dmft-dmfs, DMFT-DMFS, ICDAS II, plaque index and gingival index. No statisticallysignificant difference was found between sugar-containing and sugar-free inhalers, duration of inhaledcorticosteroid use, inhaler-spacer device use, rinsing the mouth after administration of inhaler and dmft-dmfs,DMFT-DMFS, plaque and gingival index (p>0.05). Long-term inhaled corticosteroid use was significantlyassociated with oral candidiasis (p=0.029). Also, the results showed that mothers’ educational level had asignificant effect on children’s oral health (pdmft/dmfs<0.001; pgingival index=0.049; pplaque index=0.005).Conclusion. Due to the effect of immunosuppression, long-term use of inhaled corticosteroids enhances the riskof development of the opportunistic pathogen candida. Regular dental visits and preventive dental treatmentsare needed in these patients for healthy oral status
