title: Nutritional variables related to gingival health in adolescent girls.
abstract: In order to study the nutritional variables associated with gingival health, a case-control study was designed to control strong variables whose effect on gingival status may obscure the potential effect of weaker ones, such as nutrition. Two groups of 27 gingivitis-affected and -unaffected female adolescents were selected. All were aged 17-19 years, with mean age of the two groups statistically not different. All were non-smokers, all reported daily toothbrushing frequency of twice/day or more, and none had clinical signs of hyponutrition. Mean DMFT of the two groups was statistically not different. The effect of nutritional variables, obtained by a three-day food record and by assessing the nutritional status of the girls, on presence/absence of gingivitis was evaluated by a variety of stepwise logistic regression analyses. Age (positive correlation), riboflavin, calcium and frequency of fibre intake (negative correlations) significantly explained the risk for gingivitis. Strong intercorrelation between riboflavin and calcium was also found, due to the high quantity of milk consumed by the girls, since this food provided the main source of riboflavin and calcium. The data suggest that some dietary measures may be useful for the maintenance of healthy gingival status.
