ABSTRACT
INTRODUCTION: Reflections enable students to gain additional value from a given experience. The use of Chat Generative Pre-training Transformer (ChatGPT, OpenAI Incorporated) has gained momentum, but its impact on dental education is understudied. OBJECTIVES: To assess whether or not university instructors can differentiate reflections generated by ChatGPT from those generated by students, and to assess whether or not the content of a thematic analysis generated by ChatGPT differs from that generated by qualitative researchers on the same reflections. METHODS: Hardcopies of 20 reflections (10 generated by undergraduate dental students and 10 generated by ChatGPT) were distributed to three instructors who had at least 5 years of teaching experience. Instructors were asked to assign either 'ChatGPT' or 'student' to each reflection. Ten of these reflections (five generated by undergraduate dental students and five generated by ChatGPT) were randomly selected and distributed to two qualitative researchers who were asked to perform a brief thematic analysis with codes and themes. The same ten reflections were also thematically analyzed by ChatGPT. RESULTS: The three instructors correctly determined whether the reflections were student or ChatGPT generated 85% of the time. Most disagreements (40%) happened with the reflections generated by ChatGPT, as the instructors thought to be generated by students. The thematic analyses did not differ substantially when comparing the codes and themes produced by the two researchers with those generated by ChatGPT. CONCLUSIONS: Instructors could differentiate between reflections generated by ChatGPT or by students most of the time. The overall content of a thematic analysis generated by the artificial intelligence program ChatGPT did not differ from that generated by qualitative researchers. Overall, the promising applications of ChatGPT will likely generate a paradigm shift in (dental) health education, research, and practice.
ABSTRACT
BACKGROUND: Initial caries lesions in primary teeth have presented a low progression rate after 2 years, but it could be higher in longer follow-ups. AIM: To evaluate the progression rates of sound surfaces and initial and moderate caries lesions after 7 years. DESIGN: This prospective 7-year cohort study included 639 preschool children aged 1-5 years in 2010. In 2017, 449 children were reassessed (70.3% retention rate). Dental caries was collected using the International Caries Detection and Assessment System (ICDAS) in both assessments. Incidence rate (IR) per 100 surface-years estimated the progression rates of sound surfaces and initial and moderate lesions for worse conditions. Cox regression with shared frailty evaluated the possible risk factors. RESULTS: IR was 1.0% for sound surfaces, 2.8% and 4.2% for ICDAS scores 1 and 2, respectively, and about 17.0% for moderate lesions. The most significant risk factor for the progression was the presence of cavitated lesions in other teeth. The type of surface and tooth also influenced the outcome. CONCLUSION: The progression rate of initial caries lesions in primary teeth remains low even after 7 years, but cavitated caries lesions in other teeth increase this risk. Moderate lesions demonstrate a higher risk of progression when compared to sound surfaces and initial caries lesions.
ABSTRACT
OBJECTIVES: This manuscript provides novel insights about the potential use of social media (a Facebook page, the first strategic attempt by EviDent initiative) to share evidence-based dentistry content and empowerment strategies for professionals, using quantifiable usage metrics, besides exposing the strengths and weaknesses of this knowledge translation strategy. One year-long gathered metrics were analyzed to understand information about usage patterns. RESULTS: Publications were potentially exposed to 4784 users, and subsequent interaction with the page occurred in 18% of cases. Users' involvement with page content was associated with the number of page visitors (P = .005). However, users' interaction with the page was not associated with the potential number of users that could have seen the page (P = .25). Even considering the users that approved the posts, only 7%, on average, interacted with the post's links. Although social media has effectively disseminated scientific content, our experience revealed the user's passivity in interacting with the content. We expect to overcome these barriers by developing a mobile app to offer a more interactive and dynamic interface associated with a more attractive format for posting, including images and infographics.

BACKGROUND: Comprehensive caries care has shown effectiveness in controlling caries progression and improving health outcomes by controlling caries risk, preventing initial-caries lesions progression, and patient satisfaction. To date, the caries-progression control effectiveness of the patient-centred risk-based CariesCare International (CCI) system, derived from ICCMS™ for the practice (2019), remains unproven. With the onset of the COVID-19 pandemic a previously planned multi-centre RCT shifted to this "Caries OUT" study, aiming to assess in a single-intervention group in children, the caries-control effectiveness of CCI adapted for the pandemic with non-aerosols generating procedures (non-AGP) and reducing in-office time. METHODS: In this 1-year multi-centre single-group interventional trial the adapted-CCI effectiveness will be assessed in one single group in terms of tooth-surface level caries progression control, and secondarily, individual-level caries progression control, children's oral-health behaviour change, parents' and dentists' process acceptability, and costs exploration. A sample size of 258 3-5 and 6-8 years old patients was calculated after removing half from the previous RCT, allowing for a 25% dropout, including generally health children (27 per centre). The single-group intervention will be the adapted-CCI 4D-cycle caries care, with non-AGP and reduced in-office appointments' time. A trained examiner per centre will conduct examinations at baseline, at 5-5.5 months (3 months after basic management), 8.5 and 12 months, assessing the child's CCI caries risk and oral-health behaviour, visually staging and assessing caries-lesions severity and activity without air-drying (ICDAS-merged Epi); fillings/sealants; missing/dental-sepsis teeth, and tooth symptoms, synthetizing together with parent and external-trained dental practitioner (DP) the patient- and tooth-surface level diagnoses and personalised care plan. DP will deliver the adapted-CCI caries care. Parents' and dentists' process acceptability will be assessed via Treatment-Evaluation-Inventory questionnaires, and costs in terms of number of appointments and activities. Twenty-one centres in 13 countries will participate. DISCUSSION: The results of Caries OUT adapted for the pandemic will provide clinical data that could help support shifting the caries care in children towards individualised oral-health behaviour improvement and tooth-preserving care, improving health outcomes, and explore if the caries progression can be controlled during the pandemic by conducting non-AGP and reducing in-office time.

BACKGROUND: Studies have questioned the necessity of restoring cavitated carious lesion on primary teeth, once the control of biofilm is the most important factor to arrest these lesions. This randomized clinical trial aimed to compare the survival of teeth treated with a non-restorative cavity control (NRCC) compared to resin composite restorations (RCR) on proximal carious lesion in anterior primary teeth, as well as the impact of these treatments on patient-centered outcomes. METHODS: A randomized clinical trial with two parallels arms (1:1) will be conducted. Children between 3 and 6 years old will be selected from the Center of Clinic Research of Pediatric Dentistry of Ibirapuera University (UNIB), a dental trailer (FOUSP) located on Educational Complex Professor Carlos Osmarinho de Lima, the Pediatric Dentistry Clinic of Santa Cecília University and from the Pediatric Dentistry Clinic of University Center UNINOVAFAPI. One hundred and forty-eight teeth will be randomly distributed in two experimental groups: (1) Selective removal of carious tissue and RCR; or (2) NRCC through cavity enlargement using a metallic sandpaper. The primary outcome will be tooth survival after 6, 12, 18 and 24 months. The duration and the cost of dental treatments will be considered for the estimation of the cost-effectiveness of the evaluated treatments. The discomfort reported by the participants will be measured after each treatment using the FIS scale. The participants' satisfaction and perception of the parents/legal guardians will be evaluated through questionnaires. For the primary outcome, Kaplan-Meier's survival and Long-Rank test will be used for comparison between the two groups. All the variables will be modeled by Cox regression with shared fragility. Significance will be considered at 5%. DISCUSSION: The NRCC could be an option to manage carious lesions on proximal surfaces of primary teeth, and the approach could be well accepted by the children and parents/legal guardians.

BACKGROUND: To evaluate the clinical course and interventions required during two years of follow-up of dental surfaces of deciduous molars diagnosed, and consequently treated, by two different strategies: diagnosis made by clinical examination alone or associated with radiographs. METHODS: This is a secondary analysis of a two-arm randomized clinical trial with parallel groups related to the diagnostic strategy for caries detection in preschool children. 216 children (3-6 years old) were followed-up for two years. All dental surfaces were diagnosed by visual inspection and later, through radiographic assessment. Baseline treatment was made in accordance with the results obtained by visual inspection performed alone or combined with radiographic method, considering the allocated group. Dental surfaces with no restoration needs, or those restored at the beginning of the study were followed-up for two years. The treatment decision was made according to the allocated group. The outcome was the occurrence of failure (a new caries lesion or a restoration replacement) during the follow-up. RESULTS: 4383 proximal and occlusal surfaces of deciduous molars in 216 preschool children were diagnosed and treated according to the abovementioned diagnostic strategies and followed-up for 24 months. The assessment of radiographs made change the initial decision reached by visual inspection in about 30% of the surfaces when all types of interventions were considered. However, most disagreements occurred for initial lesions, where radiographs tended to underestimate them. Discordances between methods occurred in less than 5% of all surfaces when considered lesions requiring operative treatment. For discrepancy cases, the placed interventions guided by following the radiographic results did not present less failures against those made following only visual inspection. As a matter of fact, the use of radiographs in the diagnostic strategy for caries detection in children brought more harms than benefits due to the occurrence of false-positives, overdiagnosis and lead-time bias. CONCLUSIONS: Simultaneous association of visual inspection and radiographic assessment for caries detection in preschool children causes more harms than benefits, and therefore, visual inspection should be conducted alone in the regular clinical practice. Trial registration Clinicaltrials.gov platform: NCT02078453, registered on 5th March 2014.

OBJECTIVE: To evaluate the performance of visual inspection alone and associated to radiographic and laser fluorescence (LF) methods in detecting non-evident caries lesions at adolescents' proximal surfaces. MATERIALS AND METHODS: Adolescents (12 to 17 years old) were assessed for the presence of caries lesions through visual inspection, radiographic examination, and LF method (DIAGNOdent pen), at non-cavitated (NC) and cavitated lesion (CAV) thresholds. Temporary separation with orthodontic rubbers followed by direct visual inspection was the reference standard method. Two examiners conducted the examinations, and the first examiner reassessed around 20% of the sample, to evaluate inter- and intra-examiner reproducibility, respectively. Sensitivity, specificity, accuracy, and utility values were calculated for the methods alone and combined with visual inspection using two different strategies: simultaneous and sequential combination. RESULTS: A total of 834 proximal surfaces (51 adolescents) were included. Visual inspection presented higher reproducibility values (higher than 0.98). Moreover, visual inspection presented higher sensitivity (around 0.51) than those obtained with other diagnostic strategies (varying from 0.09 to 0.20) at the NC threshold. For CAV, visual inspection presented higher specificity (0.996) than the sequential association with adjunct methods (around 0.97), but with lower sensitivity. Accuracy and utility values for combined strategies were similar or lower than those achieved with the visual inspection performed alone. CONCLUSION: Visual inspection alone performs better for detecting caries lesions in premolars and molars of adolescents than other diagnostic strategies. CLINICAL RELEVANCE: The best diagnostic strategy for caries detection of proximal caries lesions in adolescents is the visual inspection alone.

Randomised clinical trial (RCT) is the best study design to evaluate the effect of the treatment and preventive healthcare procedures. The effects of the tested treatments on patient's health are compared in terms of outcomes, which are used to evaluate the participants' health changes. However, these outcomes should be relevant for the target population. In that way, RCTs represent the type of primary study design that provides the most reliable evidence to implement therapies into the clinical practice. In this review, an outline of some aspects related to the choice of RCTs' outcomes was presented, focusing on the conduction of relevant trials in Paediatric Dentistry. The importance and necessity of defining a primary outcome were addressed, preferentially a clinically relevant endpoint. The patients should perceive this outcome, and changes in this variable should reflect directly patient's health improvement or impairment. Moreover, considerations about the objective or subjective variables, use of surrogate outcomes, and the increasing tendency to develop core outcome sets were also presented in this review. The main idea of this manuscript is the RCTs must evaluate outcomes relevant to the children's oral health in order to contribute to the implementation of treatments in the evidence-based health practice.

BACKGROUND: Visual inspection (VIS) with radiographic examination (RAD) is the recommended diagnostic strategy for detecting caries in children; however, this recommendation is based on accuracy studies. The authors conducted a clinical trial to compare the detection and subsequent treatment of carious lesions in primary molars performed with VIS alone and with RAD. METHODS: Children (3-6 years old) were randomly assigned to 2 groups according to the diagnostic strategy used for caries detection on primary molars: VIS or RAD. Participants were diagnosed and treated according to the management plan related to the allocated group. The primary outcome was the number of new operative interventions during the 2-year follow-up period. Other secondary outcomes were also compared. Comparisons were performed with Mann-Whitney test using an intention-to-treat approach. RESULTS: Of the 252 children included and randomized, 216 were followed-up after 2 years (14.3% attrition rate). There was no difference between the groups for the primary outcome (P = .476). For the secondary outcomes, the RAD group had more restoration replacements (P = .038) and more restorations performed since the beginning of the study (P = .038) compared with the VIS group. In addition, the RAD group had a higher number of false-positive results than the VIS group (P < .001). CONCLUSIONS: Simultaneous use of VIS and RAD for caries diagnosis in primary molars of children who seek dental treatment does not provide additional benefits compared with VIS alone. PRACTICAL IMPLICATIONS: Dentists should perform VIS only, not RAD, for detecting carious lesions in preschool-aged children. ClinicalTrials.gov: NCT02078453.

OBJECTIVES: To evaluate the impact of radiographic examination on changes of treatment decision related to dental caries compared to decisions guided by visual inspection alone in primary molars. MATERIALS AND METHODS: A total of 126 children aged 3-6 years who had sought dental assistance were randomly selected and examined by two calibrated examiners using visual inspection. A treatment plan regarding dental caries was generated based on this assessment. The same examiners then evaluated two bitewing radiographs, creating an additional treatment plan guided by concurrent assessment of both visual and radiographic methods. Occlusal and proximal surfaces of primary molars received a treatment decision as follows: (i) no treatment, (ii) non-operative treatment, and (iii) operative treatment. The frequency of changes in the treatment decision after radiographic examination was calculated, with subsequent Poisson multilevel regression analysis to evaluate variables influencing such changes. RESULTS: Changes from "no treatment" decided with visual inspection to "non-operative treatment" after radiographic evaluation occurred in 52 surfaces (3.2%), and changes to "operative treatment" were observed in 46 dental surfaces (2.8%). Furthermore, 50 surfaces (6.2%) had their treatment decision changed from non-operative to operative treatment after radiographic assessment. In addition, changes were significantly more frequent in children with higher caries experience, on proximal surfaces and in 1st primary molars. CONCLUSIONS: The impact of radiographic examination on changes in the treatment decision of primary molars made with visual inspection is modest. Changes are more frequent in children with higher caries experience and in proximal surfaces. CLINICAL RELEVANCE: The benefits of the radiographic method for detecting caries in children, as a protocol in the diagnostic process, seem to be overestimated; the impact of this method on changes in treatment decision made by visual examination alone is low. Radiographs could be, however, useful in particular conditions, such as in children with high caries experience.

OBJECTIVE: The aim of this study was to investigate the impact of a diagnostic workshop on undergraduate teaching-learning process for the diagnosis and management of tooth restorations. METHODS: The first stage of the study was a randomised controlled study with two parallel groups: lecture (L) and lecture coupled with a diagnostic workshop (LW). A pool of cases of tooth restorations including secondary caries and marginal defects was used for training. Theoretical knowledge, perception about the activity and practical abilities were evaluated. The second stage of the study assessed students' theoretical knowledge retention six months following intervention. All students included in the first stage of the study were exposed to LW. Hence, a new control group of students not exposed to LW was selected. One-way analysis of variance, Fisher's exact test, Kruskal-Wallis test and multilevel regression analysis were used as part of statistical analysis. RESULTS: The LW group had greater scores for the assignment of lesion severity and activity, presence of marginal defect and treatment indication than the L group (P < 0.05). Multilevel regression analysis showed a positive impact of the workshop diagnosis in the correct assessment of lesion activity (P = 0.03). There was no statistical difference between the LW and L groups in students' perception of the activity. The LW group showed greater knowledge retention after six months than the L group (P = 0.027). CONCLUSION: Lecture coupled with diagnostic workshop improved students' practical skills of diagnosis restorations and knowledge retention in the six months following intervention.

AIM: To assess the undergraduate students' performance in detecting and staging caries and assessing activity using visual inspection. DESIGN: Two independent reviewers searched the literature through PubMed/MEDLINE, Scopus, Lilacs databases, and OpenSINGLE. Meta-analyses summarized the results concerning reproducibility and accuracy at D1 (considering all lesions) and D3 (including only cavitated lesions or lesions into dentin) levels. For activity, we considered sound surfaces plus inactive caries lesions vs active lesions. Meta-regression assessed the effect of methodological variables on the outcomes. RESULTS: Fourteen studies were included. The mean reproducibility values were ≥0.52, except for interexaminer agreement when assessing caries activity (0.39; 95% CI 0.10-0.67). The intra-examiner reproducibility tended to be higher than the interexaminer reproducibility. Overall, undergraduate students' performance in staging caries lesions using visual examination was good (AUC>0.85 and DOR>25). The sensitivity values were moderate; however, these were associated with excellent specificity values. Despite few pooled studies, caries activity assessment revealed moderate overall performance, with lower pooled sensitivity than pooled specificity. Students' education level and background clinical experience had no influence on the accuracy and reproducibility of the visual inspection. CONCLUSION: Undergraduate students' performance in detecting and staging caries using visual inspection was good, although caries activity assessment still requires improvement.

The purpose of this study was to compare the performance of two different models of smartphone and a conventional camera with that of direct clinical examination in detecting caries lesions at different stages of progression in deciduous molars. The photographic equipment consisted of two smartphones (iPhone and Nexus 4) and a conventional macro camera setup. First, in the laboratory phase of the study, we compared the images of 20 exfoliated primary teeth having caries lesions at different stages. Then, in the clinical phase of the study, the images of 119 primary molars from fifteen children (3 to 6 years old) were used. All of the photographic images were taken using the previously described devices. In both groups, two examiners, blinded to the photographic equipment used, assessed the images independently on a computer screen, and classified them according to the International Caries Detection and Assessment System (ICDAS). The teeth were then examined directly by two other experienced examiners, and the consensus reached was considered the reference standard. Parameters of validity, such as percentage of correct answers, agreement with the reference standard, sensitivity, specificity and inter-examiner agreement (using the weighted kappa test) were calculated. The examiners performed similarly in both in vitro and in vivo studies. Inter-examiner reliability was approximately 0.7 for all the devices in the laboratory setting, and for the macro camera photography system in the clinical setting, but it was approximately 0.9 for the iPhone and Nexus images taken in vivo. With regard to the percentage of correct answers, the highest values were observed for sound and extensive caries lesions in both laboratory and clinical settings. The percentage of correct answers for initial and moderate lesions was particularly low in the clinical evaluation, irrespective of the camera devices used. Therefore, we concluded that photographic diagnosis using smartphone images is feasible and accurate for distinguishing sound tooth surfaces from extensive caries lesions; however, photographic images are not a good method for accurately detecting initial and moderate caries lesions.

The aims of this study were: (1) to evaluate the overall reproducibility and accuracy of the International Caries Detection and Assessment System (ICDAS) for assessing coronal caries lesions, and (2) to investigate the use of systems associated with the ICDAS for activity assessment of coronal caries lesions. Specific search strategies were adopted to identify studies published up to 2016. For the first objective, we selected studies that assessed primary coronal caries lesions using the ICDAS as a reference standard. A total of 54 studies were included. Meta-analyses summarized the results concerning reproducibility and accuracy (correlation with histology, summary ROC curves [SROC], and diagnostic odds ratio [DOR]). The latter 2 were expressed at D1/D3 levels. The heterogeneity of the studies was also assessed. Reproducibility values (pooled) were > 0.65. The ICDAS mostly presented a good overall performance as most areas under SROC were > 0.75 at D1 and > 0.90 at D3; DOR ≥6. For the second objective, we selected studies investigating activity assessment associated with the ICDAS. The meta-analyses pooled results based on the same methodology and parameters as above. Longitudinal findings regarding caries progression were described to estimate the validity of these systems. On average, the systems for activity assessment of caries lesions showed moderate values concerning reproducibility and overall performance. Active caries lesions were more prone to progress than inactive ones after 2 years. In conclusion, the ICDAS presented a substantial level of reproducibility and accuracy for assessing primary coronal caries lesions. Additional systems associated with the ICDAS that classify caries lesion activity can be useful as they are moderately reproducible and accurate.

We aimed to evaluate whether children's caries experience exerts an influence on the performance of visual and radiographic methods in detecting nonevident proximal caries lesions in primary molars. Eighty children (3-6 years old) were selected and classified as having a lower (≤3 decayed, missing, or filled surfaces; dmf-s) or higher (> 3 dmf-s) caries experience. Two calibrated examiners then assessed 526 proximal surfaces for caries lesions using visual and radiographic methods. As a reference standard, 2 other examiners checked the surfaces after temporary separation. Noncavitated and cavitated lesion thresholds were considered and Poisson multilevel regression analyses were conducted to evaluate the influence of caries experience on the performance of diagnostic strategies. Accuracy parameters stratified by caries experience were also derived. A statistically significant influence of caries experience was observed only for visual inspection, with more false-positive results in children with a higher caries experience at the noncavitated lesion threshold, and more false results at the cavitated threshold. The detection of noncavitated caries lesions in children with a higher caries experience was overestimated (specificity = 0.696), compared to children with a lower caries experience (specificity = 0.918), probably due to confirmation bias. However, the examiners underestimated the detection of cavitated lesions in children with a higher caries experience (sensitivity = 0.143) compared to lower-caries-experience children (sensitivity = 0.222), possibly because of representativeness bias. The radiographic method was not influenced by children's caries experience. In conclusion, children's caries experience influences the performance of visual inspection in detecting proximal caries lesions in primary teeth, evidencing the occurrence of cognitive biases.

The aim of this study was to evaluate the influence of initial noncavitated caries lesions on cavitated caries increment in preschool children. A 2-year cohort study was designed to include the participants of a survey on dental caries performed in 2010. Preschool children (12-59 months old) were examined for dental caries and classified as children with no caries lesions, with only initial lesions, with at least 1 moderate caries lesion, and with extensive lesions. Socioeconomic data were also collected. After 2 years, 466 children were re-examined (follow-up rate of 72.9%) only for cavitated lesions. Association between caries incidence at 2 levels of severity and caries experience and other variables was evaluated using hierarchical Poisson regression analysis. The children with moderate and extensive caries lesions at baseline presented a higher risk of presenting both outcomes than the children with no caries lesions. Nevertheless, the children with only initial lesions had a higher risk of developing at least 1 new cavitated carious lesion, but not for a more severe increment in caries. Subgroup analysis stratified by the children's age showed that the influence of the presence of initial caries lesions on cavitated caries increment was only observed in children aged 12-35 months. In conclusion, although the presence of moderate and extensive lesions at baseline is a significant predictor for cavitated caries increment after 2 years in preschool children at all ages, the presence of only initial caries lesions is also associated, but with less severe caries incidence.

BACKGROUND: The responsiveness of the Early Childhood Oral Health Impact Scale (ECOHIS) has varied greatly across studies; hence, we hypothesized that this discrepancy could be related to the complexity of dental treatment received. Thus, we aimed to evaluate the responsiveness of the ECOHIS to changes in oral health-related quality of life (OHRQoL) following dental treatments of varying complexity in preschool children. METHODS: Preschool children aged 3 to 6 years were selected; their parents responded to the ECOHIS at baseline. The parents responded to the ECOHIS again and a global transition question 30 days after the children were treated. The type of treatment received by the children was categorized according to complexity, as follows: 1) non-operative treatment only, 2) restorative treatment, and 3) endodontic treatment and/or tooth extraction. Change scores and effect sizes (ES) were calculated for total scores, as well as considering the different treatment types and global transition question responses. RESULTS: Of the 152 children who completed the study, the ECOHIS yielded large ES for total scores (0.89). The children showed increasing ES values associated with better perception of improvement, assessed by the global transition question. The magnitude of ES after treatment was related to treatment complexity (0.53, 0.92 and 1.43, for children who received non-operative treatment only, restorative treatment, and endodontic treatment and/or tooth extraction, respectively). CONCLUSIONS: Parents whose children required more complex dental treatment are more likely to perceive treatment-related changes to OHRQoL assessed with the ECOHIS.

PURPOSE: Moebius syndrome (MS) is a rare congenital facial diplegia characterized by partial or complete sixth and seventh cranial nerve palsy. Orofacial manifestations include micrognathia, increased overbite, high arched palate, morphological changes in the tongue, and dental crowding. Case reports and small case series have shown a high prevalence of caries in MS patients. The purpose of this study was to compare the prevalence of caries between individuals with Moebius syndrome and controls using the International Caries Detection and Assessment System (ICDAS). METHODS: A total of 90 participants were divided into two groups: (1) the study group, comprising 34 individuals with MS; and (2) the control group, comprising 56 age- and gender-matched healthy subjects without MS. All individuals were evaluated for the presence of caries using the ICDAS. For statistical analysis, different ICDAS scores were used as cutoff points. RESULTS: The number of carious lesions in the MS group was higher only for early-stage caries (i.e., ICDAS scores of 1 and 2; 27.0±23.0 versus 16.0±14.1 and 26.3±23.2 versus 15.2±13.6, respectively). CONCLUSION: Moebius syndrome patients have more early carious lesions than controls without the syndrome.

AIM: To investigate the risk of sound surfaces, and initial and moderate caries lesions to progress to dentine cavitation in preschool children. DESIGN: A cohort study was designed with 639 children (12-59 months old) who had been examined by visual inspection during a survey in 2010. After 2 years, 469 children were re-examined regarding the presence of dentine cavitations. The probability of progression was calculated for sound and carious (initial and moderate lesions) surfaces. Relative risk of progression and 95% confidence intervals for each condition compared with sound surfaces were calculated using multilevel Poisson regression analysis. Association with explanatory variables, including caries experience of the children, was also investigated. RESULTS: The higher the initial score attributed to the dental surface, the more likely was the progression. Moreover, children with severe lesions at baseline had higher risk of having a sound surface or a non-cavitated caries lesion progressing to cavitation when compared with caries-free children; however, this increased risk was not observed in children with only initial caries lesions. CONCLUSIONS: Initial caries lesions present a low frequency of progression. Moreover, sound surfaces and initial caries lesions in children already presenting cavitations are more likely to progress to more severe conditions.

BACKGROUND: Secondary caries is the main reason for restoration replacement, and therefore, an accurate detection of this type of condition is fundamental. AIM: To compare in vitro the performance of different conventional and quantitative light-induced fluorescence-based (QLF) methods in detecting occlusal caries around resin composite restorations in primary molars. DESIGN: Two examiners evaluated independently 42 sites adjacent to tooth-colored restorations using visual inspection (ICDAS-CARS), radiographic examination, and QLF. Histological examination was used as reference standard method. Area under the ROC curve (Az), sensitivity, specificity, and accuracy of the methods were calculated at enamel (D1) and dentin caries (D3) lesions thresholds. Intra- and interexaminer reproducibility were calculated using intraclass correlation coefficient (ICC) and kappa statistics. RESULTS: There was no difference among the methods considering Az at D1 threshold. Visual inspection, radiograph, and QLF (scores) methods presented similar sensitivities and significantly higher than those obtained with the QLF (∆F%). At D3 threshold, there were no differences among the methods regarding sensitivities, specificities, and accuracy, except for the examiner 2 with the QLF (∆F%) who achieved a very low sensitivity value. CONCLUSION: Conventional methods are similar to QLF methods for detecting caries around tooth-colored restorations in primary teeth.
