Abstract

Aim: The aim of this study was to analyze the acidogenic potential of the various commercially available fruit juices and to evaluate the salivary and plaque pH changes before and after consumption of the fruit juices that were kept at various temperatures. Materials and methods: Baseline plaque and salivary pH were measured for 30 volunteers, and the test was conducted for 4 consecutive days on which juices with a known pH was consumed, which were kept at varying temperatures. The resulting changes in the plaque and salivary pH were measured after 1, 5, 15, and 30 minutes of the consumption of the fruit juices using a portable standard digital pH meter. Results: Among the three juices compared, grape juice was found to be more acidic compared to the orange juice and pineapple juice. The pH fall was maximum after consumption of grape juice followed by orange and pineapple juice, respectively. The consumption of ice candy caused a greater fall in pH followed by the refrigerated juice and the juices that were kept at room temperature, respectively. Conclusion: Parents are unaware of the harmful effects of endogenous acids in the fruit juices and their effect on the teeth. We, as primary dental care providers, should take initiatives to provide adequate knowledge and information regarding this new trend of consuming frozen fruit juices and must strongly discourage this form of consumption as a frequent habit. Clinical significance: Though many presume that the readily available fruit juices are healthy, frequent consumption of these fruit juices causes acid dissolution of enamel as most of these juices have a pH below the critical level. Hence the present study was conducted to evaluate the erosive potential of the various commercial fruit juices. As with increased awareness by both the dentists and the parents, the problem of fruit-juice-induced tooth loss may be reduced.
