The voluntary reflux phenomenon

Abstract

Dental erosion can be caused by recurrent contact with regurgitated gastric acid and there are a number of recognised conditions in which this can occur. A previously undescribed condition, which we have termed the 'voluntary reflux phenomenon', is described, and an illustrative case history given, together with details of several other similar cases. The condition may well be first recognised by the dentist, may have serious psychiatric implications, and has features which can help distinguish it from other causes of gastric acid mediated dental erosion. These features are described and discussed, and some suggestions for initial management in general practice made, should the condition be suspected.

The reproducibility of ultrasonic enamel thickness measurements: an in vitro study

“…This is an important finding since the palatal surfaces of upper incisor teeth are commonly affected in patients with dental erosion caused by intrinsic factors. 17 The experienced observers from Groningen had no obviously better reproducibility than the inexperienced observers from Sweden. However, the observer who contributed in both places performed better in Sweden, suggesting that the teeth used there may have positively influenced the reproducibility.…”

Intrinsic Causes of Erosion

“…It has also been suggested that it affects highly intelligent, professional people [110]. The pathophysiology of rumination is poorly understood and has been incompletely studied.…”

The role of erosion in tooth wear: aetiology, prevention and management

“…Rumination is a condition when patients eat their food, swallow and then physically increase and decrease their diaphragmatic pressure and voluntarily regurgitate the food mixed with gastric acid into their mouths. Although first recognised in patients in long term care facilities it is also common in those patients with a similar psychological background as patients with eating disorders 27 . Patients with these signs and symptoms should not only receive dental care to protect their oral health, but a referral to a physician to assess their medical condition should be considered.…”
