Title:  Clinical evaluation of salivary indices and levels of Streptococcus mutans and Lactobacillus in patients treated with Occlus-o-Guide

Abstract:  Aim The aim of this study was to assess the changes over time associated with salivary indices and the presence of Streptococcus mutans and Lactobacillus in patients treated with Occlus-o-Guide. Materials and methods Two groups of patients were evaluated: a test group of 20 patients treated with Occlus-o-Guide and a control group of 20 patients not subjected to orthodontic treatment. Both groups were homogeneous for age and sex. We examined the levels of S. Mutans and Lactobacillus, the salivary flow, the buffer capacity of saliva and the Sillness and Loe plaque index (PI). The samples were taken at baseline (T0), after 3 months (T1) and after 6 months of treatment (T2). All data were compared using Student’s t test. Results The percentage of patients with a level of Streptococcus mutans able to cause caries was decreased in the test group (T0 = 10%, T1 = 0%, T2 = 0%) compared to the control group (T0 = 0%, T1 = 5%, T2 = 35%), whereas the amount of Lactobacilli was different (test group T0 = 15%, T1 = 0%, T2 = 10%; control group T0 = 0%, T1 = 5%, T2 = 35%). The total salivary flow was increased in the test group (T0 = 47, T1 = 61, T2 = 61) compared to the control group, in which it had remained almost constant (T0 = 44, T1 = 45, T2 = 45). The buffer capacity of saliva was unchanged in both groups over time; the sum of PI-plaque indices was reduced in the test group (T0 = 3, T1 = 0, T2 = 2) compared to the control group (T0 = 0, T1 = 14, T2 = 27). Conclusion Despite the presence of the Occlus-o-Guide device, patients are able to maintain a good level of oral hygiene, showing improvements of the examinated parameters at follow-ups.
