RESUMO

BACKGROUND/AIMS: The importance of external factors such as maternal and home characteristics on traumatic dental injuries needs to be investigated. The aim of this study was to evaluate the association between maternal and home characteristics and dental trauma in preschool children. MATERIAL AND METHODS: This cross-sectional study using a cluster random sample evaluated children between 3 and 4 years of age from Porto Alegre, Brazil. Mothers completed the Brazilian version of the Beck Depression and Anxiety Inventories (BDI and BAI). They answered questions about sociodemographics, maternal behaviors, and home characteristics. Dental trauma was assessed by the Children's Dental Health Survey criteria. Malocclusion and deleterious habits were also assessed. The multinomial logistic regression model was used to investigate the association of exploratory variables with different categories of dental trauma. Odds ratios (OR) and 95% confidence intervals were calculated. RESULTS: A total of 163 pairs of children and mothers agreed to participate (78.4% response rate). The prevalence of dental trauma was 49.8%. Mother's work outside the home, overjet, and anterior crossbite were associated with the occurrence of enamel trauma, while having a younger mother, families having more siblings, and having a mother with university education were associated with increased odds of dentin/pulp trauma. CONCLUSION: Depression and anxiety in the mothers were not associated with dental trauma, while malocclusion characteristics were more relevant for less severe, enamel trauma. Socioeconomic and home environment characteristics played a role in more severe, dentin/pulp trauma.

RESUMO

OBJECTIVES: We investigated factors associated with failure of adhesive restorations in primary teeth and whether repair may increase the survival of failed restorations placed in high-caries risk children. MATERIALS AND METHODS: The sample comprised children who attended a university dental service to perform restorative treatment in primary teeth. Data were collected retrospectively from clinical records to assess the longevity of restorations. The outcomes were calculated in two levels: "Success" (Level 1)-when any re-intervention was considered as failure; "Survival" (Level 2)-when repaired restorations were considered clinically acceptable. The Kaplan-Meier survival test was used to analyze the longevity of restorations. Multivariate Cox regression with shared frailty was used to assess factors associated with failures (p < 0.05). RESULTS: A total of 584 primary teeth restorations (178 patients) were included in the analysis. The longevity of restorations up to 36 months (Level 1) was 34.8% (AFR 29.6%). Multi-surface restorations showed significantly more failures than single-surface ones (HR 1.69; 95% CI 1.18, 2.41), and endodontically treated teeth presented more failures compared to vital teeth (HR 2.22; 95% CI 1.35, 3.65). There was an increase in restoration survival when repair was not considered as failure (p < 0.001). The survival of repaired restorations (Level 2) reached 43.7% (AFR 24.1%). CONCLUSIONS: Adhesive restorations placed in primary teeth of high-caries risk children showed restricted longevity; however, the repair of failed restorations has increased its survival over time. CLINICAL RELEVANCE: Repair is a more conservative and technically simple procedure that increases the survival of failed restorations in primary teeth.

RESUMO

BACKGROUND: The authors conducted a systematic review of randomized controlled trials comparing the risk of experiencing restoration failure in primary teeth after complete and selective carious tissue removal of soft dentin. METHODS: The authors searched electronic databases (PubMed [MEDLINE], Scopus, Cochrane Central Register of Controlled Trials) and the ClinicalTrials.gov Web site with manual searching and cross-referencing for trials reporting restoration failure after follow-up of 6 months or longer. Two reviewers independently selected studies, extracted data, and assessed the risk of bias and quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. The authors performed intention-to-treat and per-protocol meta-analyses and calculated odds ratios (OR) as effect estimates in the random-effects model. RESULTS: From 327 potentially eligible studies, the authors selected 23 for full-text screening and included 4. Results showed increased risk of experiencing restoration failure (intention-to-treat analysis, OR [95% confidence interval] 1.74 [1.01 to 3.00], and per-protocol analysis, OR [95% confidence interval] 1.79 [1.04 to 3.09]) after selective carious tissue removal of soft dentin. The risk of bias was high, and the quality of evidence was low. CONCLUSIONS: Selective carious tissue removal of soft dentin may increase the risk of experiencing restoration failure in primary teeth. However, the evidence level is insufficient for definitive conclusions. PRACTICAL IMPLICATIONS: Patients with restorations performed after selective carious tissue removal of soft dentin should have shorter recall visit intervals to evaluate the restorations' quality and control caries disease, allowing for more conservative approaches, such as repair, in cases of defective restorations.

RESUMO

AIM: This retrospective study investigated the prevalence of defective restorations in a public dental service and factors associated with re-intervention in primary teeth. DESIGN: The sample consisted of all clinical records (census) of children presenting restorations in primary teeth, who had undergone dental treatment in a public set during 1-year period. For analysis, only restorations presenting defects related to esthetic, functional, or biological reasons at first clinical examination were included. The outcome 'Success' was set when the restoration received no treatment (monitored), refurbishing, sealing of margins, or was repaired. Otherwise, 'Failure' was set whenever the restoration was either replaced or if another treatment affecting the restoration was necessary (endodontic treatment or tooth extraction). Poisson regression model was used to assess the prevalence of patient- and tooth-related factors that may influence the re-intervention decision (repair or replacement). RESULTS: From a total of 302 restorations placed in 114 children, 37.7% presented some type of defect. Restorations with recurrent caries were more frequently present in caries-active patients (P = 0.03) and were frequently replaced (95% CI, 1.05-3.22, RR = 1.84, P = 0.03). CONCLUSION: Presence of recurrent caries influences the re-intervention decision, leading to restoration replacement in most cases.

RESUMO

OBJECTIVES: The aim of this study is to evaluate the association between caries lesions progression and oral health-related quality of life (OHRQoL) among Brazilian preschools, after 2 years. MATERIALS AND METHODS: At baseline, 163 children (3-4 years old) enrolled in 12 public primary care services in Porto Alegre/RS-Brazil were evaluated. After 2 years, 119 children were re-evaluated. Calibrated examiners employing the ICDAS criteria conducted clinical examinations. A socio-demographic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale were applied to the parents of the children at baseline and 2-year follow-up. Data analysis was performed using a hierarchical approach based in a conceptual framework testing by Poisson regression. RESULTS: The number of surfaces that progressed from baseline to 2-year follow-up was associated with an increased negative impact on OHRQoL. CONCLUSIONS: Caries progression increased the negative impact on OHRQoL. CLINICAL RELEVANCE: The progression of caries lesions could negative impact on OHRQoL in Brazilian preschoolers.

RESUMO

OBJECTIVE: The objectives of this study are to isolate, cultivate, and characterize stem cells from the pulp of carious deciduous teeth (SCCD) and compare them to those retrieved from sound deciduous teeth (SHED--stem cells from human exfoliated deciduous teeth). MATERIAL AND METHODS: Cells were obtained of dental pulp collected from sound (n = 10) and carious (n = 10) deciduous human teeth. Rate of isolation, proliferation assay (0, 1, 3, 5, and 7 days), STRO-1, mesenchymal (CD29, CD73, and CD90) and hematopoietic surface marker expression (CD14, CD34, CD45, HLA-DR), and differentiation capacity were evaluated. RESULTS: Isolation success rates were 70 and 80 % from the carious and sound groups, respectively. SCCD and SHED presented similar proliferation rate. There were no statistical differences between the groups for the tested surface markers. The cells from sound and carious deciduous teeth were positive for CD29, CD73, and CD90 and negative for CD14, CD34, CD45, and HLA-DR and were capable of differentiating into osteogenic, chondrogenic, and adipogenic lineages. CONCLUSION: SCCD demonstrated a similar pattern of proliferation, immunophenotypical characteristics, and differentiation ability as those obtained from sound deciduous teeth. These SCCD represent a feasible source of stem cells. CLINICAL RELEVANCE: Decayed deciduous teeth have been usually discarded once the pulp tissue could be damaged and the activity of stem cells compromised. These findings show that stem cells from carious deciduous teeth can be applicable source for cell-based therapies in tissue regeneration.

RESUMO

PURPOSE: To analyze the outcomes of partial caries removal (PCR) restorations in primary teeth. METHODS: The sample of this retrospective study comprised primary teeth that had been treated with PCR by undergraduate students and were selected from the dental records of patients who were receiving treatment at the School of Dentistry, Federal University of Rio Grande do Sul - Brazil (UFRGS), from 2007 to 2012. Records containing clinical and/or radiographic follow-up data of restorations with PCR in primary teeth were included in the analysis. Factors potentially associated with treatment failure were investigated, such as the number of surfaces restored, type of capping material and restorative material used, the presence of visible plaque, and the gingival bleeding index. RESULTS: The sample comprised 254 teeth in 118 subjects; the follow-up period ranged from 1 to 50 months. The overall success rate for PCR was 80.3% (204/254). A significant association was found between high final visible plaque index and PCR failure (P = 0.002).

RESUMO

PURPOSE: To compare the effect of incomplete caries removal (ICR) and indirect pulp capping (IPC) with calcium hydroxide (CH) or an inert material (wax) on color, consistency and contamination of the remaining dentin of primary molars. METHODS: This double-blind, parallel-design, randomized controlled trial included 30 children presenting one primary molar with deep caries lesion. Children were randomly assigned after ICR to receive IPC with CH or wax. All teeth were then restored with resin composite. Baseline dentin color and consistency were evaluated after ICR, and dentin samples were collected for contamination analyses using scanning electron microscopy. After 3 months, restorations were removed and the three parameters were re-evaluated. In both groups, dentin became significantly darker after 3 months. RESULTS: No cases of yellow dentin were observed after 3 months with CH compared to 33.3% of the wax cases (P < 0.05). A statistically significant difference over time was observed only for CH regarding consistency. CH stimulated a dentin hardening process in a statistically higher number of cases than wax (86.7% vs. 33.3%; P = 0.008). Contamination changed significantly over time in CH and wax without significant difference between groups. It was concluded that CH and wax arrested the carious process of the remaining carious dentin after indirect pulp capping, but CH showed superior dentin color and consistency after 3 months.

RESUMO

PURPOSE: To evaluate the clinical performance of adhesive restorations of resin composite and resin-modified glass-ionomer cements in primary molars. METHODS: This randomized clinical trial included subjects (5-9 year-old children) selected at two university centers (UFRGS and UNIFRA). The sample consisted of 132 primary molars presenting active cavitated carious lesions (with radiographic involvement of the inner half of the dentin), located on the occlusal and occlusal-proximal surface. The sample was randomly divided into three groups, according to the restorative material: (G1) universal restorative system (Adper Single Bond 2 system and Filtek Z350); (G2): Resin-modified glass-ionomer cement (Vitremer); and (G3): Low shrink restorative system (Filtek P90). The restorations were clinically and radiographically followed every 6 months for up to 18 months using the USPHS modified criteria for clinical evaluation. Survival estimates for restoration longevity were evaluated using the Kaplan-Meier method. Log-rank test (P< 0.05) was used to compare the differences in the success rate according to the type of the restorative material. RESULTS: The type of restorative material used did not influence the longevity of the restorations. After clinical follow-up, there was no statistical difference in the rates of success for the three materials used to restore active cavitated carious lesions in primary molars. The survival rates for the follow-up were similar regarding the number of restored surfaces and the caries removal technique (partial or complete). Mean estimated time of survival was 17.2 months (95% CI: 16.7-17.7). Estimated survival rates of the restorations were 100%, 98%, 88% and 65% at 1, 6, 12 and 18 months of clinical evaluations, respectively.

RESUMO

PURPOSE: To clinically evaluate the status of caries lesions adjacent to restorations (AdjCL) in primary molars, and its relationship to the child's carious activity and marginal restoration integrity. METHODS: Three independent examiners (trained, calibrated and blinded) evaluated 64 randomly selected restorations (occlusal and occluso-proximal) by the AdjCL status (kappa = 0.844), the restoration marginal integrity (kappa = 1) and the radiographic presence of lesions in the occlusal restoration margins (kappa = 1). One of the examiners also evaluated the child's carious activity (kappa = 1). The variables were related to the outcome through Chi-square and Fisher's Exact analysis (alpha = 5%). RESULTS: A prevalence of 40.63% AdjCL (88.46% inactive) was seen, with no significant association to the child's carious activity (P = 0.23). The association of the absence of AdjCL and the presence of marginal integrity was statistically significant (P = 0.013). Also, the presence of AdjCL occurred especially around older restorations (P = 0.044).

RESUMO

AIM: To evaluate the dentin microhardness of primary teeth undergoing indirect pulp capping (IPC) after partial caries removal. MATERIALS: Primary molars were treated with IPC, restored with self-etching primer (Clearfil SE Bond; CSE), and filled with composite resin (Filtek Z250) with (n = 10) or without (n = 7) a calcium hydroxide base liner (Dycal; Dy). After tooth exfoliation, the microhardness of the demineralized dentin remaining under the restoration (n = 17) was analyzed and compared with that of sound and carious primary dentin (n = 20). Microhardness measurements were obtained from the deepest portion of the cavity until the roof of the pulp chamber. Data were analyzed by Kruskal-Wallis test (p < 0.05). RESULTS: There was no difference in microhardness values at all depths between the treated groups (DY and CSE), but when the exfoliated carious teeth were included, the CSE had significantly higher values at 35-microm depth. This difference was only detected in the DY group after a depth of 200 microm. At 700 microm, there was no difference in microhardness values between all 4 groups. CONCLUSIONS: Primary teeth that underwent IPC showed the same microhardness, regardless of the capping material used.

RESUMO

PURPOSE: To investigate in situ the influence of gaps in the development of secondary caries lesion in adhesive restorations. METHODS: 10 volunteers utilized intra-oral appliances, containing three human dental blocks (enamel and dentin), representing the three different groups (two restored, one sound): (1) restored with resin composite using the total acid etch adhesive technique (37% H3PO4 + Single Bond + Z250); (2) restored with resin composite but without acid etching (Single Bond + Z250); (3) and sound blocks (control group). The dental blocks (n=30) were randomly positioned inside the intra-oral appliances, and covered by a porous tissue (gabardine base) to induce a cariogenic biofilm. The volunteers used the appliances 24 hours daily for a 28-day period, removing just during meals and oral hygiene. Eight times a day, a 20% sucrose solution was dripped onto the blocks. Five minutes later, the appliance was washed with distilled water and replaced in the oral environment. After the experimental period, the dental blocks were removed from the appliance and examined by visual examination to detect the presence or the absence of an active carious lesion (kappa= 0.89). Posteriorly, they were prepared for the polarized light microscopy examination, which was performed to describe enamel surface characteristics on the restored and unrestored blocks with active caries lesion (kappa= 1). RESULTS: The visual examination demonstrated that almost all (29/30) of the blocks showed non-cavitated active caries lesion on the enamel surface. The microscopic evaluation showed non-cavitated caries lesions on enamel surfaces for all groups. In the restored blocks (with and without the total etch technique), the demineralization was first identified as an outer lesion that follows the enamel prism directions, and in some cases, reached the cavity walls. The results showed that caries lesion development adjacent to the restoration was determined by the cariogenic challenge of the oral environment, instead of the restoration adhesive quality, and the wall lesion was determined by the prism orientation, regardless of the presence of gaps.

RESUMO

INTRODUCTION: Our objective was to compare vertical alveolar growth in areas adjacent to infraoccluded deciduous molars with growth in areas of deciduous molars and normal occlusion for a period of at least 1 year by using digital subtraction radiography. METHODS: This case-control study included 40 pairs of panoramic radiographs of growing patients with infraoccluded deciduous molars and 40 pairs of radiographs of patients without infraoccluded deciduous molars. One radiograph at baseline was obtained at diagnosis, and the other at least 1 year later. The subjects and the controls were matched according to chronologic age and time interval between the 2 radiographs. The 2 groups were compared with regard to vertical alveolar growth and vertical tooth movement. Measurements were assessed by using nonparametric tests (Mann-Whitney and Friedman) and a multiple comparison test. Significance was set at 5%. RESULTS: A statistically significant difference was observed between the groups with regard to vertical alveolar growth measured on the bone crest between the first permanent molars and second premolars. CONCLUSIONS: Vertical alveolar growth between the first permanent molar and the second premolar adjacent to the infraoccluded teeth was smaller than in areas adjacent to teeth with normal occlusion.

RESUMO

PURPOSE: The aim of this retrospective follow-up study was to verify the distance between the cementoenamel junction (CEJ) and the alveolar bone crest (ABC) in bitewing radiographs. METHODS: Radiographs were digitized and divided into groups by: age, proximal crown surface status (sound→sound and unsound→unsound), tooth, and timing of radiograph. The CEJ-ABC distances were measured on the distal surface of the first primary molar and/or the mesial surface of the second lower primary molar, using the Image Tool software. RESULTS: The results revealed interactions between the following variables: timing of radiograph-age, age-tooth, timing of radiograph - proximal crown surface status and age- proximal crown surface status. It has been detected that CEJ-ABC distances have significantly increased with time, particularly in terms of assessment of primary lower first molars. However, this increase is greater in unsound when compared to sound surfaces. CONCLUSION: This study suggests that an increase in the CEJ-ABC distance is directly associated with aging in a normal periodontium in the primary dentition and that the presence of unsound surfaces can be a risk indicator for the development of alveolar bone loss.

RESUMO

PURPOSE: To evaluate clinical and radiographic outcomes of indirect pulp treatment (IPT) in primary molars after long-term function (up to 60 months). METHODS: Teeth with deep carious lesions without signs and symptoms of irreversible pulpitis were divided by random allocation into two groups, according to the capping material utilized over demineralized dentin: experimental group (1): self-etching adhesive system (Clearfil SE Bond); and control group (2): calcium hydroxide liner (Dycal). Both groups were filled with resin composite (Z250) and submitted to a clinical and radiographic monitoring period until exfoliation. RESULTS: After the follow-up period (up to 60 months), no statistical difference was found between groups (P= 0.514). The overall success rate reached 78%. The failures occurred after the first year period recall.

RESUMO

This study investigates the profile of teaching primary tooth pulp therapy practiced by Brazilian dental schools. A multiple-choice questionnaire was sent by e-mail to 191 dental schools in Brazil, addressed to the pediatric dentistry Chairperson. The two-part survey consisting of multiple-choice questions regarding specific materials and techniques on pulp therapies, moreover, hypothetical clinical scenarios were presented so that the respondents could guide the treatment approach. The questionnaires were returned by 46.5% of the dental schools. Ninety-five percent of surveyed schools teach IPT for the treatment of deep carious lesions in dentin and indicate the calcium hydroxide as capping material (59.3%). The direct pulp capping is taught by 68.7% of schools and calcium hydroxide (97%) was the capping material most indicated. Pulpotomy is taught in 98.7% of schools and formocresol (1:5 dilution) was the medicament of choice (50%). All schools taught pulpectomy and Iodoform paste was the filling material preferred (55%). The results showed a lack of consensus in certain modalities and techniques for primary tooth pulp therapy taught by Brazilian dental schools.

RESUMO

PURPOSE: The aim of the present crossover study was to evaluate professional toothbrushing as a method for diagnosing gingivitis in children. MATERIALS AND METHODS: Thirty-four preschool children who had gingival bleeding > or = 10% and without proximal restorations/carious lesions were included in the study. Examinations comprised two gingival indices recorded at a 15-min interval, in the following sequences: the Ainamo and Bay gingival bleeding index (GBI1) followed by the brushing index (BI2) and vice versa (BI1-GBI2). Half of the children started the study in the first sequence and the other half in the second. After a 3- to 4-day washout period, the indices were again recorded with individuals changing the sequences. Data analysis considered GBI as the gold standard, and sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) were also calculated. RESULTS: The overall mean value of gingival bleeding at the first examination was 18.85 +/- 9.24%. Validation of toothbrushing performed after GBI (BI2) resulted in values for SE, SP, PPV and NPV of 0.59 (95% CI, 0.55 to 0.63), 0.92 (95% CI, 0.91 to 0.93), 0.64 (95% CI, 0.60 to 0.69) and 0.90 (95% CI, 0.89 to 0.92), respectively. BI performed before GBI (BI1) resulted in similar SE, SP, PPV and NPV. Percentage agreement of GBI1-BI2 and BI1-GBI2 was 83.5% and 85.9%, respectively. CONCLUSIONS: Professional toothbrushing can be suggested as a method for the diagnosis of gingival inflammatory status in children, especially as an indicator of gingival health.

RESUMO

PURPOSE: The purpose of this study was to evaluate the effect of the materials used for indirect pulp treatment (IPT) on the long-term outcome of primary molar teeth. METHODS: Forty-eight teeth with deep carious lesions, but without signs and symptoms of irreversible pulpitis, were randomly divided into 2 groups, according to the material placed on the demineralized dentin remain: (1) experimental group, adhesive system (Scotchbond Multipurpose); and (2) control group, calcium hydroxide liner (Dycal). Both groups were followed by a resin restoration application. RESULTS: After 4 to 5 years, the clinical and radiographic success rates between groups were similar (group 1=14 of 15; group 2=8 of 10; P=0.350). Subsequent to exfoliation, scanning electron microscopy revealed the presence of a hybrid layer at the resin-dentin interface and a microtensile bond strength of 9.63 MPa (group 1). Histological analysis showed that the pulp health status was similar in both groups. CONCLUSIONS: Indirect pulp treatment has a high clinical and radiographic long-term success rate in primary teeth and is not material-dependent.

RESUMO

Changes in the midpalatal suture and the alterations in intercanine and intermolar widths with the use of the quad-helix appliance were evaluated. Study casts and occlusal radiographs from 10 patients with a mean age of 4 years and 10 months (SD 11 months) were analyzed. A statistically significant palatal suture widening was observed in all cases. The proportion of dental tipping accomplished with the treatment was greater than opening of the suture.

RESUMO

OBJECTIVE: To evaluate the clinical and radiographic outcomes (24 months) of indirect pulp treatment (IPT) in primary teeth when a self-etching primer or a calcium hydroxide layer was used over the remaining carious dentin. STUDY DESIGN: Primary molar teeth with deep carious lesions without signs and symptoms of irreversible pulpitis were divided into two groups, according to the capping material: Experimental group (1): self-etching adhesive system (Clearfill SE Bond); and Control group (2): calcium hydroxide liner (Dycal). Both groups were followed up after application of a resin restoration (3M - Z250). RESULTS: After 2 years of clinical and radiographic follow-up, no statistical difference was found between groups (p = 1). The overall success rate reached 87%. CONCLUSION: These results demonstrate that IPT has a high clinical and radiographic performance in primary teeth and is not dependent on the capping material used over the demineralized dentin.
