RESUMO
The aim of this study was to evaluate changes in the frequency of use of minimum intervention (MI) techniques for caries management during the COVID-19 pandemic. A questionnaire was applied through the SurveyMonkeyTM platform to evaluate changes in the dentist's frequency of use of noninvasive, microinvasive, minimally invasive, and mixed interventions, nonaerosol or aerosol productive, to manage dental caries before and during COVID-19 pandemic. Differences in the use of MI techniques were analyzed by Wilcoxon test, and the effect size (ES) was calculated. An α = 0.05 was adopted. A total of 781 dentists answered the questionnaire; most of them were female (76.4%), with 30s (76.4%), graduated over 10-24 years ago (38%) in public dental schools (62%), graduated in southwest of Brazil (38%), that work in clinical environment (66.8%) and in private jobs (53.4%). During COVID-19, among the sample, 91 respondents were not working. In relation to the noninvasive techniques, only the use of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) decreased during the COVID-19 pandemic (p < 0.01; ES = 0.11). The frequency of sealants to repair defective restorations was the only microinvasive technique that increased during the pandemic (p < 0.01; ES = 0.03). Among the minimally invasive techniques, the use of atraumatic restorative treatment increased significantly (p < 0.01; ES = 0.06), while the use of air abrasion decreased (p = 0.02; ES = 0.04) during COVID-19 pandemic. Moreover, nonrestorative cavity control (mixed intervention) increased during pandemic period (p < 0.001; ES = 0.11). Although the results demonstrated differences in the use of some procedures, a very small magnitude of the effect was perceived, demonstrating that the influence of COVID-19 pandemic was very little, if any, in the use of MI techniques for caries management. Moreover, the use of MI strategies was already well established between Brazilian dentists before the pandemic period.

There is a need to investigate methods to increase children's health knowledge. Therefore, the aim of this study was to systematically evaluate the literature on playful educational interventions in health literacy aimed at children aged 6-12 years. For this purpose, the Cochrane Library, EMBASE, LILACS, PubMed, Scopus, Web of Science and grey literature were searched for relevant studies. Randomized, quasi-randomized or non-randomized clinical trials, in which the primary outcome was health literacy in children, were included. Due to the heterogeneity of the studies, the data were qualitatively evaluated. Eleven studies were included in this analysis. Most of the studies were randomized (n = 10). Among the health issues addressed in these studies, obesity prevention was the most studied (n = 5). All participants had low methodological quality, and the most commonly used interventions were games, dramas and theatre plays. Although most studies have pointed to an increase in health knowledge after interventions, it was not possible to determine whether such knowledge was retained over time, whether it effectively changed health behaviours, or if it led to the effective adoption of a healthier lifestyle. Health literacy through playful methods is potentially effective in increasing health knowledge and changing health behaviours. However, literature on its impact on the adoption of healthy lifestyles is inconclusive. Future research with fewer limitations and better methodological designs may help selecting the best intervention strategy to promote health literacy.

BACKGROUND: There is no consensus on which molar incisor hypomineralization (MIH) indices are more suitable for epidemiological surveys. AIM: To compare the operational aspects and diagnostic ability of the MIH index (simplified/MIH_s and extended/MIH_e) with the MIH-Severity Scoring System (MIH-SSS) in classifying and diagnosing MIH. DESIGN: This cross-sectional study assessed the indices in a homogeneous group of 680 6- to 10-year-old schoolchildren in Bauru, Brazil, who had at least one first permanent molar, ensuring consistent conditions. Followed by toothbrushing, the children seated on school chairs were examined by the two calibrated researchers under artificial lighting, using mouth mirror and WHO probe, and chronometer recording the duration of examinations. RESULTS: The prevalence of MIH was 24.7%. The most common characteristic of MIH was demarcated opacity, with a prevalence of 81.7% and 85.45% according to the MIH_s and the MIH-SSS, respectively. A positive association was observed among the MIH_s, the MIH_e, and the MIH-SSS (chi-squared test; p < .01). The MIH-SSS demonstrated a shorter average application time than both versions of the MIH index (ANOVA/Tukey; p < .05). Additionally, fluorosis was found to be the most prevalent among other developmental defects of enamel, with a prevalence of 38.38%. CONCLUSION: All systems effectively diagnosed MIH and its characteristics.
RESUMO
OBJECTIVE: To describe the caries lesion transition pattern in permanent tooth surfaces over 2 years among a convenience sample of children in a fluoridated (0.8 ppm F) low-socioeconomic community of Brazil. MATERIAL AND METHODS: One hundred forty-nine schoolchildren (7-12 years) were examined for caries using Nyvad criteria at baseline and after 2 years. Descriptive analysis was used to evaluate caries lesion transition patterns. RESULTS: Less than 1% of sound surfaces and non-cavitated caries lesions at baseline progressed to cavitation stage within 2 years. 12.7% of the active non-cavitated (ANC) lesions became inactive, 34.7% regressed to sound, 48.0% remained active, and 4.6% progressed to cavitated/filled stages at follow-up. Similarly, 55.2% of the inactive non-cavitated (INC) lesions at baseline remained inactive, 33.3% regressed to sound, 8.0% progressed to cavitated/filled lesions, while only 3.5% progressed to ANC lesions. CONCLUSION: The caries lesion transition pattern in this child population exposed to water fluoride and fluoride toothpaste showed that a low proportion of sound surfaces and non-cavitated lesions progressed to cavitation within the 2-year follow-up. Caries arrest was mainly ascribed to a high proportion of active non-cavitated lesions regressing to sound or inactive lesions. CLINICAL RELEVANCE: Caries activity can be controlled by regular exposure to fluoridated water and fluoridated toothpaste.

OBJECTIVES: This two-arm, parallel-group, tooth-randomised, controlled noninferiority clinical trial aimed to compare survival rates between the sealing and restoring of cavitated occlusal carious lesions in dentine [International Caries Detection and Assessment System (ICDAS) 5] of deciduous molars using resin-modified glass-ionomer cement (RMGIC) and to assess caries progression radiographically. MATERIALS AND METHODS: A total of 68 molars with ICDAS 5 occlusal lesions were randomly allocated into two groups, a sealing group (n = 31), in which RMGIC was placed directly over the carious lesion, and a restoration group (n = 37), in which a restoration with the same material was placed after selective caries removal. During the baseline and follow-up visits, dental caries was registered and caries activity was assessed according to a visuotactile criterion. At baseline, patient caries status (dmf-t) and cavity depth and extent (mesiodistal and buccolingual) were measured before RMGIC placement. An independent and blinded examiner evaluated the treated teeth using the USPHS criteria after one and two years. Standardised interproximal radiographs were taken for caries progression assessments. RESULTS: During the follow-up period, no lesion progression was observed radiographically. After one year (n = 60; 27 sealed and 33 restored) and two years (n = 48; 23 sealed and 25 restored) of follow-up, the treatment success rates were 78.8% and 76.0% in the restoration group and 59.3% and 47.8% in the sealing group, respectively. Multivariate Cox regression showed that lesions smaller than 2 mm in the mesiodistal extent were less prone to fail after one year (p = 0.03). However, survival curves (log-rank test) were statistically significantly different only after two years (p < 0.001). CONCLUSIONS: Sealing ICDAS 5 occlusal lesions of deciduous molars using RMGIC achieved lower survival rates than restorations. Both sealing and restoration effectively arrested caries progression for two years. Clinical relevance Sealing dentine carious lesions can be effective for treating lesions involving the inner and outer half of the dentine. Ultraconservative treatments can arrest carious lesions presenting obvious cavitation in primary molars. TRIAL REGISTRATION: ReBEC Register no. RBR-225n35.

AIM: To develop, apply, and evaluate a virtual learning object (VLO) for teaching undergraduate dental students and paediatric dentists to diagnose and manage molar incisor hypomineralization (MIH). DESIGN: This controlled educational intervention included 170 undergraduate dental students and 50 paediatric dentists. The student intervention group (VLOG) was trained by the VLO, the control group of students (CG) received a synchronous virtual class, and the group of paediatric dentists (PDG) was trained by the VLO. Pre-test and post-test data were analyzed with a mixed one-way and Tukey's post hoc ANOVA test (α = 0.05). The answers to the questionnaire were analyzed with the one-way ANOVA test and Tukey's post hoc test (α = 0.05). RESULTS: The values obtained in the pre-test were significantly lower than those obtained in the post-test for all groups. The specialists showed a higher level of knowledge before and after the MIH training compared with the students (p < .001). Similarly, statistical differences were found in the level of knowledge, which increased after MIH training (p < .001). There were no differences between the CG and VLOG. CONCLUSIONS: The level of knowledge increased in all groups after training regardless of the method used. VLOG works similar to traditional teaching approaches.

OBJECTIVES: To describe a new molar-incisor hypomineralization (MIH) severity scoring system (MIH-SSS) that focuses on the defects' severity and to assess the system's validity and reliability over 3 years. MATERIALS AND METHODS: One hundred eighty-one children diagnosed with MIH were examined by MIH-SSS. For reliability assessment, 15-20 children were examined twice, and analyses were performed at the tooth level at four different cutoff points. Follow-up examinations were performed over 36 months. Only teeth presenting MIH opacities at baseline were assessed. Odds ratios were calculated to evaluate the chance of post-eruptive breakdown (PEB) occurrence related to the colors of MIH defects. Survival curves were created for different types of teeth (molars and incisors) based on white and yellow opacities. The Kaplan-Meier method was used with PEB as the outcome. RESULTS: According to the MIH-SSS, kappa values ranged from 0.82 to 0.88. Regarding the longitudinal evaluation, for molars and incisors, yellow/brown opacities had a significantly higher chance to evolve to dentin breakdown compared with white/creamy opacities (OR = 2.54, OR = 10.58, respectively). Survival analysis showed that the occurrence of PEB was more frequent in the first evaluation period (12 months). CONCLUSION: MIH-SSS, which provides detailed information about MIH severity, is a valid instrument presenting high reliability. Yellow/brown opacities progressed more than did white/creamy opacities. CLINICAL RELEVANCE: It is of paramount importance to detect any surface breakdown as early as possible to be able to avoid pain and caries progression. Moreover, this is the first paper that shows survival curves for MIH enamel breakdown over time.

BACKGROUND: Dental caries morbidity stages and their impact on oral health-related quality of life (OHRQoL) have not yet been established. AIM: To compare the association of dental caries morbidity stages with OHRQoL in children and adolescents from public schools of Patos-PB, Brazil. DESIGN: A cross-sectional study was performed on 461 students at 8-10 years and 454 at 11-14 years. Caries was evaluated by Caries Assessment Spectrum and Treatment (CAST) instrument. The maximum CAST code per individual was registered. OHRQoL was assessed using the Child Perceptions Questionnaires for children (CPQ8-10 ) and adolescents (CPQ11-14 ). RESULTS: Morbidity stage was the most prevalent caries condition in children (40.8%) and adolescents (38.1%). Factors associated with higher CPQ8-10 scores in the multivariate regression analysis after adjustments were age [9 years, prevalence ratio (PR): 1.24; 95% confidence interval (CI): 1.06-1.45; and 10 years, PR: 1.32, CI: 1.13-1.55] and dental caries status [morbidity, PR: 1.23, CI: 1.03-1.48; and severe morbidity, PR: 1.30, CI: 1.04-1.61]. The factor associated with higher CPQ11-14 scores was dental caries status [morbidity, PR: 1.20, CI: 1.00-1.44]. CONCLUSIONS: The OHRQoL of children was negatively associated with morbidity and severe morbidity stages of dental caries, while for adolescents, only morbidity had a negative association with their OHRQoL.

AIM: This study aimed to investigate the prevalence of hypersensitivity in molar-incisor hypomineralization (MIH)-affected molars through a census carried out in 8-year-old schoolchildren. METHODS: Examinations were conducted by a calibrated examiner, using the Nyvad criteria for caries diagnosis and a new criterion for MIH assessment. For hypersensitivity assessment, all MIH-affected molars were included. Nonaffected molars from the same child were used as controls. Air blast reaction was measured using the Visual Analogue Scale (VAS) and the Schiff Cold Air Sensitivity Scale (SCASS) scale, while tactile hypersensitivity was scored using VAS only. Statistical analysis was performed using the Kruskal-Wallis test followed by Dunn's multiple comparisons test for quantitative data. χ2 was used for the comparison of categorical data. RESULTS: In total, 631 children were assessed, of whom 102 had MIH-affected molars (16.1%). Of these, 51.7 and 8.7% presented enamel and dentin carious lesions, respectively. Regarding the number of teeth, 239 molars were MIH affected (59.8%), with 188 (78.7%) being classified as mild (opacities only), 20 (8.4%) as moderate (posteruptive enamel breakdown), and 31 (13%) as severe (posteruptive breakdown involving dentin/atypical restorations). Hypersensitivity was recorded in only one control molar, while the prevalence of hypersensitivity in MIH-affected molars was 34.7%, being of low intensity and more prevalent in moderate (55%) and severe cases (51.6 %) than in mild cases (29.8%, p = 0.008). An association between hypersensitivity and the presence of mild and moderate cases was observed. Although the same association was observed for severe cases, it was not considered a reliable information as 90% of the MIH-affected molars with posteruptive breakdown involving dentin were affected by carious lesions. It is known that dental caries is a confounding factor for the presence of hypersensitivity. CONCLUSIONS: Hypersensitivity was significantly higher in MIH-affected molars than in nonaffected molars, being associated with MIH teeth presenting opacities and posteruptive enamel breakdown.

BACKGROUND: Dental caries diagnosis and management have changed over time. AIM: To identify the treatment decision-making process performed by paediatric dentists, after caries detection using CAST instrument (Caries Assessment Spectrum and Treatment), for enamel (CAST 3) and non-cavitated dentin caries lesions (CAST 4) before and after analysing radiographic images. DESIGN: Seventy-four paediatric dentists were invited to participate. Twelve clinical cases were presented online, and treatment decisions before and after the analysis of bitewing radiographs were evaluated. RESULTS: Sixty-one specialists answered the questionnaire. The necessity for radiographs was significantly associated with the presence and depth of the caries lesion (P < 0.0001). CAST 3 lesions were preferentially monitored before and after the radiographic assessment. For CAST 4 lesions limited to the outer half of dentin, treatments indicated before and after radiographic analysis were sealant (33%) and restoration (40%). For the lesions in the inner half of dentin, restoration was the most cited before (45%) and after (84%) radiographs. The radiographic depth was the only significant independent variable when "change in the treatment option" was analysed by the regression model (P < 0.001). CONCLUSIONS: Enamel lesions were treated through less invasive treatments. Radiographs influenced the decision, especially for the lesions that involved the inner half of dentin.

PURPOSE: To assess children's oral health-related quality of life (OHRQoL) three years after implementation of three treatment protocols for managing cavitated carious dentine lesions in primary molars by parent proxy report with the Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS) and to assess the level of agreement between the children's self-reporting and the parents' reporting of the children's OHRQoL. MATERIALS AND METHODS: Schoolchildren aged 6 to 7 were included in a clinical trial that compared three treatment protocols for managing cavitated carious dentine lesions: CRT (Conventional Treatment); ART (Atraumatic Restorative Treatment) and UCT (Ultraconservative Treatment). Before treatment (baseline), the OHRQoL of 273 children was assessed by B-ECOHIS using the parents'/caregivers' proxy report. Three years later, 147 parents/caregivers filled in the questionnaire while the children, ages 9 to 10, were interviewed. The t-test and one-way ANOVA were used for statistical analysis. RESULTS: No difference was observed between treatment protocols in regard to the children's OHRQoL (p = 0.41). A significant reduction in the parent distress domain was observed when baseline and parents'/caretakers' responses after three years (p = 0.01) were compared. The level of agreement between the parents'/caregivers' and children's scores was low. Children scored lower on the impact of oral health on their quality of life than their parents/caregivers did (p < 0.0001). CONCLUSION: The use of UCT, a largely non-restorative protocol, leads to a perception of OHRQoL by parents/caregivers that is similar to the ART and CRT protocols after three years. Parent distress decreased over time. Children and parents/caregivers disagreed about children's OHRQoL.

The objectives of the study were to quantify the dentine mineral concentration (DMC) in teeth restored conventionally, according to the atraumatic restorative treatment (ART) and ultraconservative (UCT) protocols (open cavities and small ART restorations), and the DMC underneath the open cavities of teeth managed by UCT versus nontreated, open cavities. We studied 50 teeth with restorations/open cavities, 39 restored teeth (9 by conventional restorative treatment [CRT], 17 by ART, and 13 by UCT) and 16 teeth with open cavities. Each restoration/open cavity was scanned using microcomputed tomography, with 3 hydroxyapatite disks with respective densities of 1.24, 1.33, and 1.57 g/cm3 as a reference. Images were reconstructed and the greyscale images were converted into DMC values. For each restoration/open cavity, 15 measurements of dentine immediately underneath and from the corresponding area in sound dentine were taken. DMC was expressed as a percentage of the DMC of sound dentine. ANOVA and the Student t test were used for statistical analysis. The mean DMC underneath restorations of the ART protocol group (98.93%) was statistically significantly higher than that of the UCT protocol group (91.98%), but not of the CRT protocol group (91.33%). On multiple surfaces, mean DMC in the axial area (94.32%) was statistically significantly higher than in the gingival area (92.80%). The mean DMC of open cavities managed by UCT protocol (89.05%) was statistically significantly higher than in nontreated open cavities (83.90%). In conclusion, a dentine-hypermineralized area underneath ART restorations was observed. Managing open cavities with a toothbrush and fluoride toothpaste (the UCT protocol) resulted in higher mineralized dentine underneath the cavity than in nontreated open cavities.

PURPOSE: To determine whether the frequency of microleakage at the margin of the tooth-restoration interface in primary molars restored with high-viscosity glass-ionomer cement (HVGIC) differs from that of primary molars restored with amalgam. MATERIALS AND METHODS: The HVGIC restorations were performed according to the ART method. A total of 19 naturally exfoliated primary molars (10 amalgam and 9 ART/HVGIC) with clinically assessed intact restorations fulfilled the inclusion criteria. SEM analyses using replicas were performed to assess the microgap presence and size of the tooth-restoration interface The depth of a microgap was measured from histological sections after infiltration of 50% (w/v) AgNO3 solution. Independent variables were restorative material, age of restoration, and number of tooth surfaces. Data analyses included Fisher's Exact version of the chi-squared test, independent t-test and one-way ANOVA. RESULTS: More ART/HVGIC than amalgam-restored teeth were gap free (p = 0.14). The mean gap size for teeth with a gap between amalgam (322.0 µm) and ART/HVGIC (201.0 µm) restorations did not differ statistically significantly. AgNO3 infiltration was not influenced by restorative material or age of restoration. Infiltration in multiple-surface was higher than in single-surface restorations (p = 0.02). CONCLUSION: The occurrence of marginal microleakage in primary molars restored by ART/HVGIC is no different from that observed in primary molars restored with amalgam. Microleakage was deeper in multiple-surface than in single-surface restorations. Despite the presence of microleakage, restoration functionality up to exfoliation is secured, reinforcing the importance of biofilm removal and behavioral education of patients.

RESUMO
OBJECTIVES: The aim of this study was to compare the caries-preventive effect and the retention rates of sealants prepared with a new modified and a high-viscosity glass-ionomer cement (GIC) in recently erupted first permanent molars. MATERIALS AND METHODS: Fifty-six children (224 teeth) were included in a split-mouth randomised clinical trial. All children had their four first permanent molars sealed with either Clinpro XT Varnish (CXT) or Fuji IX GP FAST (FJ). FJ sealants were placed according to the ART protocol. Retention rates and caries-preventive effect of both materials were assessed clinically after 24 months, and survival curves were created according to the Kaplan-Meier method. For sealant retention rates, analyses were performed according to both the traditional method and modified sealant retention categorisation. RESULTS: FJ sealants were retained longer in comparison to CXT sealants (p < 0.05), regardless of the categorisation used. In relation to the caries-preventive effect, no statistically significant differences were observed between materials (p = 0.99). Sealants prepared with the high-viscosity GIC according to the ART protocol survived longer than those prepared with the modified GIC, but both materials were equally effective in preventing cavitated dentine lesions over 24 months. CONCLUSION: We concluded that GIC-based sealants are effective in preventing dentine caries lesions.

BACKGROUND: This study aimed to evaluate the survival rate of glass hybrid restorations placed under the atraumatic restorative treatment (ART) technique in first permanent molars affected by molar incisor hypomineralization (MIH). METHODS: Sixty teeth with severe MIH associated to carious dentin lesions without pulp involvement were included. Treatments were performed by one trained dentist using the ART approach and restored with a glass hybrid restorative system (Equia Forte, GC®) on school premises. Treatments were evaluated after 6 and 12 months by an independent examiner using the modified ART criterion. Data analysis involved descriptive statistics and actuarial success analysis. RESULTS: The sample comprised 24 (54.54%) girls and 20 (45.45%) boys with a mean age of 10.55 (±1.25) years. In regard to the number of surfaces involved in the restorations, 29 (48.3%) comprised one surface and 31 (51.7%) two or more surfaces. Considering cavity extent, 25 (41%) presented dentin cavitation without cusp weakness, 23 (37.7%) with large dentin cavitation with cusp weakness and 13 (21.3%) with large dentin cavitation with the breakdown of one or more cusps. Only 4 teeth required local anesthesia. A success rate of 98.3% after 6 and 12 months was observed, as only one restoration failed. The only failure occurred in a restoration involving three or more sur-faces presenting the breakdown of all cusps. CONCLUSION: Restorations using a glass hybrid restorative system and performed in the field with the ART technique proved, after 12 months of evaluation, to be an effective approach to preserving first permanent molars affected by MIH. TRIAL REGISTRATION: REBEC-RBR-8drccq (17/06/15).

AIM: The aim of this study was to compare the caries experience of children with and without molar-incisor hypomineralisation (MIH). METHODS: A case-control study was designed in which 130 children aged between 7 and 13 years with MIH (cases) were matched with 130 children without the condition (controls) according to age, sex, and school. Dental caries and MIH were assessed using the Caries Assessment Spectrum and Treatment (CAST) and European Academy of Paediatric Dentistry (EAPD) criteria, respectively, by three examiners. CAST was converted into DMFT/dmft; the Kruskal-Wallis test was performed to analyse whether dmft/DMFT was influenced by the severity of MIH. Associations between MIH and dental caries were analysed at child and tooth levels: between and within subjects, respectively. To correlate MIH severity and the occurrence of dental caries, the Cochran-Armitage test was used. RESULTS: The mean age of the children was 9.63 ± 1.29 years. The mean dmft for cases was 1.23 ± 1.99 and for controls 1.71 ± 2.22 (p > 0.05). For the DMFT, the mean scores for cases and controls were 0.45 ± 0.90 and 0.07 ± 0.25, respectively (p < 0.001). The between-subject analysis showed no difference in relation to enamel carious lesions; however, the prevalence of dentine carious lesions was significantly higher in children with MIH than in those without the condition. The same pattern was seen for the within-subject analysis. It was observed that the increase in MIH severity resulted in more teeth being affected by dentine carious lesions (p = 0.0003). CONCLUSION: Children with MIH presented a higher experience of caries in the permanent dentition than those without the condition. MIH was considered a risk factor for caries development.

Caries detection is fundamental to understanding the oral health status of a population and is the basis for caries diagnosis for individual patients. Although different caries detection/diagnosis criteria are available, none of them include the total spectrum of dental caries (which ranges from a sound tooth to a tooth lost due to caries) other than the Caries Assessment Spectrum and Treatment (CAST) instrument. The CAST codes and descriptions were submitted to experienced epidemiologists from across the world for obtaining face and content validity. Its construct validity and reproducibility under field conditions were tested in child and adult populations, and showed a high level of agreement between examiners. Compared to what is usually reported in the literature, CAST provides more relevant information on caries prevalence, experience, and severity. CAST is straightforward and easy to use. A manual with valuable information about how to apply CAST and report its results has been published in order to facilitate communication among researchers, oral health planners, and medical professionals. Feedback from researchers indicates that CAST is considered an asset and that reporting results after using CAST is uncomplicated. More research about the effects of CAST in different cultures and age groups is required.

BACKGROUND: Failed restorations in primary teeth are not always re-restored. Is re-restoration not required anymore? OBJECTIVE: To compare survival rates of primary molars with intact and defective amalgam and ART restorations. METHODS: A total of 649 restored primary molars, of which 162 were assessed with defective restorations for mechanical reasons, from a cluster-randomised controlled clinical trial, were followed up over a period of 3.5 years. Restored primary molars, extracted because of dental sepsis or toothache, were considered a failure. Primary molars with defective restorations were followed up from the time they were assessed defective. Data were analysed using PHREG model with frailty correction, Wald test, t-test, and jackknife procedure. RESULTS: The survival rate of primary molars with intact restorations (96.3%) was statistically significantly higher than that of primary molars with defective restorations (75.9%) over a 3-year period (P < 0.0001). Neither the effect of treatment protocol (amalgam or ART) (P = 0.05) nor the type of surface (single or multiple) (P = 0.73) was observed with respect to the survival rate of restored primary molars. CONCLUSIONS: Survival rates for primary molars with intact and defective amalgam and ART restorations were high. The 3-year survival rate of primary molars with intact restorations was significantly higher than that of primary molars with defective restorations.

AIM: Epidermolysis bullosa (EB) represents a highly rare subgroup of skin diseases that affects skin and mucous membrane. The aim of the present study was to assess caries prevalence and its associated factors in EB subjects. Salivary status was also assessed. MATERIALS AND METHODS: Ten subjects with EB who were under supervision were selected (cases) and matched by age and gender with unaffected individuals (controls). Dental caries were recorded using the World Health Organization (WHO) criteria. Oral hygiene and dietary habits were investigated by clinical examination and questionnaires. Both nonstimulated and stimulated saliva were collected and salivary pH, buffering capacity and mouth opening were evaluated. RESULTS: The results showed that the median decay-missing-filled teeth was significantly higher (p = 0.0094) in EB cases 5 (3.9-20.3) than in controls 3 (2-3.25). The groups also differed when food consistency was analyzed. Individuals with EB have a higher intake of soft food. In addition, the median mouth-opening values from cases (0.84-2.84 cm) and controls (4.3-4.9 cm) have shown to be statistically different (p = 0.007). Considering the salivary parameters, none of them showed significant differences among groups. CONCLUSION: Epidermolysis bullosa subjects present higher caries scores and might be related to their physical condition and dietary habits. CLINICAL SIGNIFICANCE: There is a lack of information about oral status in EB subjects. Hence, our findings add useful information regarding the relationship between caries prevalence and associated risk factors in EB subjects.
