Self-induced vomiting and dental erosion--a clinical study.

Uhlen MM, Tveit AB, Stenhagen KR, Mulic A - BMC Oral Health (2014)

Bottom Line: Dentine lesions were most often found on lower first molars, while upper central incisors showed enamel lesions most frequently.The majority of the erosive lesions (48.6%) were found in those with the longest illness period, and 71.7% of the lesions extending into dentine were also found in this group.Dental erosion commonly affects individuals with ED experiencing SIV, and is more often found on the palatal/lingual surfaces than on the buccal in these individuals, confirming a common clinical assumption.

ABSTRACT

Background: In individuals suffering from eating disorders (ED) characterized by vomiting (e.g. bulimia nervosa), the gastric juice regularly reaches the oral cavity, causing a possible risk of dental erosion. This study aimed to assess the occurrence, distribution and severity of dental erosions in a group of Norwegian patients experiencing self-induced vomiting (SIV).

Methods: The individuals included in the study were all undergoing treatment at clinics for eating disorders and were referred to a university dental clinic for examinations. One calibrated clinician registered erosions using the Visual Erosion Dental Examination (VEDE) system.

Results: Of 72 referred patients, 66 (63 females and three males, mean age 27.7 years) were or had been experiencing SIV (mean duration 10.6 years; range: 3 - 32 years), and were therefore included in the study. Dental erosions were found in 46 individuals (69.7%), 19 had enamel lesions only, while 27 had both enamel and dentine lesions. Ten or more teeth were affected in 26.1% of those with erosions, and 9% had ≥10 teeth with dentine lesions. Of the erosions, 41.6% were found on palatal/lingual surfaces, 36.6% on occlusal surfaces and 21.8% on buccal surfaces. Dentine lesions were most often found on lower first molars, while upper central incisors showed enamel lesions most frequently. The majority of the erosive lesions (48.6%) were found in those with the longest illness period, and 71.7% of the lesions extending into dentine were also found in this group. However, despite suffering from SIV for up to 32 years, 30.3% of the individuals showed no lesions.

Conclusions: Dental erosion commonly affects individuals with ED experiencing SIV, and is more often found on the palatal/lingual surfaces than on the buccal in these individuals, confirming a common clinical assumption.

Figure 1: Number of affected surfaces with erosive lesions in relation to duration of SIV.

Mentions: The group of individuals (n = 16) with the longest duration of SIV (>10 years) had 71.7% of the dentine lesions and 40.4% of the enamel lesions (Table 1).Of the individuals included in the study, eight (17.4%) had five or more teeth with dentine lesions. Only seven of these individuals answered the question of the duration of SIV, and for those who did, the mean duration was 17.1 years (range: 6 – 28). Ten participants (21.7%) had five or less surfaces with erosions (Figure 1). Seven of the individuals had lesions on occlusal surfaces only. Eight of those with five or less involved tooth surfaces had been suffering from ED for 5 – 10 years, while two patients reported duration of 26 and 28 years, respectively.
