Abstract

OBJECTIVE: Our aim was to study if bulimia nervosa (BN) has an impact on salivary gland function and if such changes are related to dental erosion.

STUDY DESIGN: Twenty women with BN and twenty age- and gender-matched controls participated. Flow rate and composition of whole and glandular saliva, as well as feeling of oral dryness were measured. Dental erosion was measured on casts.

RESULTS: Compared with control subjects, unstimulated whole saliva (UWS) flow rate was reduced in persons with BN, primarily owing to intake of medication (P = .007). No major compositional salivary changes were found. In the BN group, the dental erosion score was highest and complaints of oral dryness were more frequent.

CONCLUSIONS: The BN persons had impaired UWS, mainly owing to medication; increased feeling of oral dryness; and more dental erosion. Dental erosion was related to the duration of eating disorder, whereas no effect of vomiting frequency or intake of acidic drinks on reduced UWS was observed.
