“…Thus, previous dental caries was a predictor for new dental caries. This finding lends support to the hypothesis that previous caries experience is indicative of the disease in the future, 16,24,25,26 especially in cases in which children are exposed to other risk factors for dental caries.…”

Incidence of dental caries in primary dentition and risk factors: a longitudinal study Abstract: The objectives of this prospective, longitudinal, population-based study were to estimate the incidence of dental caries in the primary dentition, identify risk factors and determine the proportion of children receiving dental treatment, through a two-year follow up. The first dental exam was conducted with 381 children aged one to five years, at health centers during immunization campaigns; 184 of them had dental caries and 197 had no caries experience. The second exam was carried out two years later at a nursery or at home with the same individuals who participated in the first exam. The diagnosis of dental caries was performed using the dmft criteria. Parents were interviewed regarding socioeconomic indicators. Descriptive, bivariate and adjusted Poisson regression analyses were performed. Among the 381 children, 234 were reexamined after two years (non-exposed: 139; exposed: 95). The overall incidence of dental caries was 46.6%. The greatest incidence of dental caries was found in the group of children with previous caries experience (61.1%). Among the children without dental caries in the first exam, 36.7% exhibited caries in the second exam. The majority of children (72.6%) received no treatment for carious lesions in the two-year interval between examinations. Children with previous dental caries (RR: 1.52, 95%CI: 1.12-2.05) had a greater risk of developing new lesions, compared with the children without previous dental caries. The incidence of dental caries was high and most of children's caries were untreated. Previous caries experience is a risk factor for developing new carious lesions in children.

“…Previous studies demonstrated that both criteria could predict lesion depth and assess caries lesion activity. 21,22,24,[32][33][34] Although not reaching statistical significance, this small, pilot clinical study provided preliminary information to establish the use of the QLF method. Further clinical investigations to establish threshold or cut-off values to distinguish among the lesion stages and a larger sample size for clinical application will be necessary.…”

Pilot clinical study to assess caries lesion activity using quantitative light-induced fluorescence during dehydration

et al. 2017

"Pilot clinical study to assess caries lesion activity using quantitative light-induced fluorescence during dehydration," J. Biomed. Opt. Abstract. This study aimed to evaluate the ability of quantitative light-induced fluorescence (QLF) to assess caries lesion activity using visual examination (VE) as the gold standard. Twenty-four visible white spot lesions on buccal surfaces were examined from 23 children, ages 9 to 14 years. At baseline, the surface was hydrated with water, and thereafter, it was dehydrated with continuous compressed air during image acquisition. QLF images were acquired at 0 (baseline), 5, and 15 s. QLF variables [QLF V : fluorescence loss (ΔF), lesion size (S), ΔQ: ΔF × S] was recorded. Changes-in-QLF V per second (ΔQLF V ) were determined: ΔQLF V ¼ ðQLF VN − QLF VBaseline Þ∕N, where N indicates dehydration time. One experienced dentist conducted VE independently using a dental unit's light, compressed air, and explorer. QLF V and ΔQLF V of the active group (n ¼ 11) were compared with those of the inactive group (n ¼ 13) using two-sample t -tests. As the surface was dehydrated, S and ΔQ values of the active group increased, whereas QLF V of the inactive group showed only a small change. ΔQLF V of the active group were larger than those of the inactive group; however, the difference did not reach statistical significance (p > 0.11). Within the limitations of this study, QLF data indicated increments for lesions designated as active and minimal change for lesions defined as inactive.

“…In fact, few studies have been concerned with the usefulness of the methods and the possible benefits for patients [Baelum et al, 2012;Mendes et al, 2012]. In addition, only few papers evaluated the prognosis of caries lesions in longitudinal studies [Nyvad et al, 2003;Ferreira Zandona et al, 2012;Guedes et al, 2014]. Thus, more information on these issues and on other points related to the clinical relevance of visual inspection is necessary.…”

Clinical Relevance of Studies on the Accuracy of Visual Inspection for Detecting Caries Lesions: A Systematic Review

et al. 2015

Although visual inspection is the most commonly used method for caries detection, and consequently the most investigated, studies have not been concerned about the clinical relevance of this procedure. Therefore, we conducted a systematic review in order to perform a critical evaluation considering the clinical relevance and methodological quality of studies on the accuracy of visual inspection for assessing caries lesions. Two independent reviewers searched several databases through July 2013 to identify papers/articles published in English. Other sources were checked to identify unpublished literature. The eligible studies were those which (1) assessed the accuracy of the visual method for detecting caries lesions on occlusal, approximal or smooth surfaces, in primary or permanent teeth, (2) used a reference standard, and (3) reported data about sample size and accuracy of the methods. Aspects related to clinical relevance and the methodological quality of the studies were evaluated. 96 of the 5,578 articles initially identified met the inclusion criteria. In general, most studies failed in considering some clinically relevant aspects: only 1 included study validated activity status of lesions, no study considered its prognosis, 79 studies did not consider a clinically relevant outcome, and only 1 evaluated a patient-centred outcome. Concerning methodological quality, the majority of the studies presented a high risk of bias in sample selection. In conclusion, studies on the accuracy of the visual method for caries detection should consider clinically relevant outcomes besides accuracy; moreover, they should be conducted with higher methodological quality, mainly regarding sample selection.
