Abstract: The purposes of this study were to investigate: (1) the effect of chewing raisins on the plaque pH in orthodontic patients. (2) The effect of chewing raisins on the bacterial count in dental plaque. (3) The in vitroeffect of raisins on growth of plaque bacteria. Twenty 12- to 18-year-olds, orthodontic patients participated in this randomized controlled study. Raisins were tested against sucrose and sorbitol as positive and negative controls. The pH of saliva was measured with digital pH meter prior to (baseline) and 2, 5, 10, 20, and 30 minutes after chewing raisins or rinsing with a control solution. Plaque samples were obtained from five sites using a sterile periodontal probe. S. mutans, lactobacilli and P. gingivalis were isolated and counted. The bacteria were incubated in nutrient media at 37oC for 24 hours. The antibacterial activity of raisins was tested against commonly used antibiotics using the sensitivity test by disc diffusion method. The results showed significant differences in the minimum pH in raisins and sucrose groups when compared to sorbitol (P≤ .05 and P≤ .01 respectively). Raisins showed less pH drop than sucrose (P≤ .05). The pH in raisins group showed rapid recovery and did not reach the critical value for decalcification (5.5). Bacterial counting showed significant reduction in the number of studied microorganisms after chewing raisins. Raisins showed significant growth inhibition of all studied strains which was comparable or even more than antibiotics tested. The results of the present study support the beneficial oral effects of raisins, but would recommend further clinical researches before the use of raisins as an alternative to the traditional remedies for prevention of dental caries and gingivitis during orthodontic treatment.
