Interest in a new test for caries risk in adolescents undergoing orthodontic treatment

Abstract

It has been reported that patients undergoing orthodontic treatment present a high risk of caries. Recently, an immediate chair-side test was proposed, displaying the intra-oral lactic acid production of cariogenic bacteria. The aim of this 12-month follow-up prospective cohort study was to evaluate the association between having a high score on this test and caries occurrence in 110 young patients scheduled for orthodontic treatment. Caries occurrence was studied by Kaplan-Meier curves and Multivariate Cox models allowed the examination of its association with covariates. Fifty four patients developed at least one carious lesion during the follow-up period. At baseline, approximately 70% of the patients presented a high risk of caries according to the test and this number came close to 80% by the study's completion. According to the Kaplan-Meier estimator, 51% (CI(95%) 0.40, 0.60) of the sample would have developed at least one carious lesion during the follow-up. The test score was then associated with age, DMFT, and caries occurrence. This study showed that a high test score at baseline associated with a high DMFT predicted a high risk of caries (RR = 2.6). Taking the patient's age into consideration, an increase of 1 year resulted in a 10% decrease of the risk of caries occurrence (RR = 0.89). Within the limits of this longitudinal study, it may be concluded that this test is useful to evaluate the risk for dental caries in adolescents with orthodontic treatment. Furthermore, the distribution of the lesions in our sample suggests specific clinical approaches for this group of patients.

Efficacy of pastes containing CPP-ACP and CPP-ACFP in patients with Sjögren’s syndrome

“…New approach to the assessment of the cariogenic potential of plaque is focused on the result of fermentation rather than on the identification of one bacterial species or one acid [59]. When the pH of dental plaque is associated with other cariogenic factors, such as DMFT/DMFS index, it becomes a valuable tool for caries risk prediction [60]. In the present investigation, significant influences of both CPP-ACP and CPP-ACFP on plaque pH have been noticed.…”

Effects of orthodontic treatment with a fixed appliance on the caries experience of patients with high and low risk of caries

“…Limited studies were carried out by clinical examinations with various devices such as fluorescence light, 1 DIAGNOdent, 8 an SEM study, 9 and a cariogram study. 10 Some authors 1,8 suggested that orthodontic treatment with a fixed appliance may be compatible with an increased incidence of caries; thus, orthodontists were criticized. Some authors, 9e12 however, found no relationship between fixed orthodontic treatment and caries experience.…”

THE EFFECTS OF FIXED ORTHODONTIC TREATMENT PERIOD ON WHITE SPOT LESION PREVALENCE AND DMFT INDEX-Sabit Ortodontik Tedavi Süresinin Beyaz Nokta Lezyonu Oluşum Sıklığı ve DMFT İndeksi Üzerine Etkileri

“…To date, clinical detection of WSLs has been carried out primarily by means of traditional methods such as visual inspection with Gorelick index after air drying and tactile examination by dental probing. However, the subjectivity and lack of reproducibility of these approaches, together with the prerequisite of the presence of a significantly advanced lesion, have led to the introduction of several optical techniques during recent decades: the optical caries monitor, use of quantitative laser and light-induced fluorescence, digital imaging with fiber-optic transillumination, laser fluorescence, and computer analysis of digital photographs (14)(15)(16)(17)(18). Because of the nonexistence of these techniques, we consider that visual inspection was appropriate in the present study.…”
