Assessment of Caries Risk Through Clinical and Salivary Parameters in Pediatric Patients with Cleft Lip and Palate.

OBJECTIVE: The aim of this study is to assess caries-related indicators (DMFT and ICDAS indices), plaque index, salivary pH and buffering capacity, and dietary and oral hygiene habits in patients with cleft lip and/or palate undergoing orthodontic treatment, compared with a control group of healthy patients. METHODS: This pilot case-control study included 26 patients undergoing orthodontic treatment, 13 patients with cleft lip and/or palate and 13 healthy individuals. The following variables were assessed: diet and oral hygiene through a questionnaire; salivary pH and buffering capacity; caries risk, using the DMFT and ICDAS indices; and plaque index, using the ImageJ Software. RESULTS: No statistically significant differences were detected in the DMFT index, salivary pH, and plaque index; nor in the diet, oral hygiene and salivary buffering capacity. A slightly higher plaque index was observed in patients with cleft lip and/or palate compared to healthy patients. There was a statistically significant difference in the location of plaque, with a higher incidence in the upper central incisors in the study group. CONCLUSION: This pilot study suggests no statistically significant differences in the DMFT index, plaque index, salivary pH, and buffering capacity between patients with cleft lip and/or palate and healthy controls undergoing orthodontic treatment. However, a higher incidence of bacterial plaque on the upper central incisors was observed in patients with cleft lip and/or palate.
