RESUMO

This in vitro study aimed to evaluate the effect of a silane-containing universal adhesive used with or without a silane agent on the repair bond strength between aged and new composites. Forty nanohybrid composite resin blocks were stored in distilled water for 14 d and thermo-cycled. Sandpaper ground, etched, and rinsed speciments were randomly assigned into four experimental groups: silane + two-step etch-and-rinse adhesive system, two-step etch-and-rinse adhesive system, silane + silane-containing universal adhesive system, and silane-containing universal adhesive system. Blocks were repaired using the same composite. After 24 h of water storage, the blocks were sectioned and bonded sticks were submitted to microtensile testing. Ten unaged, non-repaired composite blocks were used as a reference group to evaluate the cohesive strength of the composite. Two-way ANOVA and Tukey's tests were used to analyze average µTBS. One-way ANOVA and Dunnet post-hoc tests were used to compare the cohesive strength values and bond strength obtained in the repaired groups (α = 0.05). The µTBS values were higher for the silane-containing universal adhesive compared to the two-step etch-and-rinse adhesive system (p = 0.002). Silane application improved the repair bond strength (p = 0.03). The repair bond strength ranged from 39.3 to 65.8% of the cohesive strength of the reference group. Using universal silane-containing adhesive improved the repair bond strength of composite resin compared to two-step etch-and-rinse adhesive. However, it still required prior application of a silane agent for best direct composite resin repair outcomes.

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

Sleep bruxism (SB) is a masticatory muscle activity during sleep that can cause several consequences to the stomatognathic system. This systematic review investigated the impact of SB on oral health-related quality of life (OHRQoL) of 0- to 6-year-old children. Literature search was undertaken through PubMed/MEDLINE, LILACS, Scopus, TRIP, Livivo databases, and grey literature. The search was conducted with no publication year or language limits. Two reviewers independently selected the studies, extracted the data and assessed the risk of bias. The quality of evidence was assessed using GRADE. From 185 potentially eligible studies, three were included in the review. All studies were conducted in Brazil, published between 2015 and 2017, and used the B-ECOHIS instrument to evaluate OHRQoL. Two studies found no association between SB and OHRQoL, whereas one showed a significant negative impact of SB on the OHRQoL of children. SB was associated with respiratory problems, presence of tooth wear, dental caries, malocclusion as well as income and pacifier use. Risk of bias ranged from moderate to high, and the quality of evidence was judged as very low. The evidence is currently insufficient for definitive conclusions about the impact of SB on OHRQoL of children.

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

This study aimed to evaluate the bond strength of a universal adhesive system to enamel surrounding real-life carious cavities. Twenty-eight permanent molars (n = 7) with carious lesions in dentin were subjected to selective carious tissue removal to firm dentin and had their crowns sectioned longitudinally. A universal adhesive system (Single Bond Universal [SBU] used in either etch-and-rinse and self-etch strategies) was compared with an etch-and-rinse Adper Single Bond 2 (ASB) and a self-etch Clearfil SE Bond (CSE) adhesive systems (control systems). Adhesives were applied on the enamel, assumed demineralized, surrounding the cavity margins and on sound enamel (control substrate). Composite cylinders were built (0.72 mm2) and microshear bond strength (µSBS) test was performed after 24 h of water storage. The µSBS values (MPa) were analyzed using two-way ANOVA and Tukey's post hoc tests (α = 0.05). Bond strength values obtained in demineralized enamel surrounding carious cavity margins were significantly lower than that obtained in sound enamel (distant from carious cavity margins) (p = 0.035). The bonding strategy of the SBU did not influenced the bond strength values, which were higher than that obtained with ASB. CSE showed similar µSBS values to ASB and SBU in the self-etch mode. In conclusion, the bond strength to enamel assumed demineralized is lower than to sound enamel. The enamel surrounding carious cavities jeopardize the bonding of universal adhesive system. The bond strength of universal adhesive is similar, regardless to bonding strategy.

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

Objective: To compare the teaching of the pulpectomy in primary teeth among graduate and undergraduate Brazilian dental schools. Material and Methods: From August 2015 to July 2016, an 11-question survey was sent to 44 graduate and 207 undergraduate dental schools. Data obtained were summarized using descriptive statistics. Results: The response rate was higher from graduate (56.8%) than undergraduate (41.1%) courses. Pulpectomy was taught by all participating schools. More than 90% of the undergraduate and graduate courses recommend the use of hand instruments for canals debridement, but the widening of root canals was advised in 69.4% of undergraduate and in 84% of graduate schools. Regarding the irrigatings, 1% sodium hypochlorite as a single irrigating solution was the most taught for both biopulpectomy and necropulpectomy. The iodoform-based Guedes-Pinto paste as the single indication was the preferred root canal filling material in undergraduate schools (30.6%), while the zinc oxidethickened calcium hydroxide paste as the single option was the most recommended in graduate courses (36%). Endodontic hand file associated with lentulo drill for filling root canals was recommended by most courses. Overall, biopulpectomy was performed in one session, while necropulpectomy led two sessions. Periapical radiograph for diagnosis and final obturation was the most adopted conduct by undergraduate (68.2%) and graduate (72%) schools. Gutta-percha and glass ionomer cement were preferred materials to seal the entrance of the pulp chamber. Conclusion: There was variability in the techniques and materials taught to perform pulpectomy in primary teeth among Brazilian graduate and undergraduate dental schools. Calcium hydroxide paste has been used in similar proportion to iodoform-based paste.

RESUMO

Abstract: This study aimed to evaluate the bond strength of a universal adhesive system to enamel surrounding real-life carious cavities. Twenty-eight permanent molars (n = 7) with carious lesions in dentin were subjected to selective carious tissue removal to firm dentin and had their crowns sectioned longitudinally. A universal adhesive system (Single Bond Universal [SBU] used in either etch-and-rinse and self-etch strategies) was compared with an etch-and-rinse Adper Single Bond 2 (ASB) and a self-etch Clearfil SE Bond (CSE) adhesive systems (control systems). Adhesives were applied on the enamel, assumed demineralized, surrounding the cavity margins and on sound enamel (control substrate). Composite cylinders were built (0.72 mm2) and microshear bond strength (µSBS) test was performed after 24 h of water storage. The µSBS values (MPa) were analyzed using two-way ANOVA and Tukey's post hoc tests (α = 0.05). Bond strength values obtained in demineralized enamel surrounding carious cavity margins were significantly lower than that obtained in sound enamel (distant from carious cavity margins) (p = 0.035). The bonding strategy of the SBU did not influenced the bond strength values, which were higher than that obtained with ASB. CSE showed similar µSBS values to ASB and SBU in the self-etch mode. In conclusion, the bond strength to enamel assumed demineralized is lower than to sound enamel. The enamel surrounding carious cavities jeopardize the bonding of universal adhesive system. The bond strength of universal adhesive is similar, regardless to bonding strategy.

RESUMO

PURPOSE: To systematically review the literature to analyze the influence of endodontic irrigating solutions on the bond strength of adhesives to coronal enamel or dentin. MATERIALS AND METHODS: The PubMed/MEDLINE, Web of Science and Scopus electronic databases were used to select laboratory studies related to the research question, without publication year or language limits. From 2461 potentially eligible studies, 2451 were selected for full-text analysis, and 97 were included in the systematic review. Two authors independently selected the studies, extracted the data, and assessed the risk of bias. Pooling bond strength data were calculated using RevMan5.1 with random effects model (α = 0.05), comparing control (no endodontic irrigating solution) and experimental groups (one or more endodontic solutions). RESULTS: No significant difference was found between the control and experimental groups (p = 0.12) in the overall meta-analysis and in the meta-analysis excluding chlorhexidine (p = 0.06). High heterogeneity was found in the meta-analyses. Most included studies in the systematic review were scored as having a high risk of bias. CONCLUSION: The different endodontic irrigating solutions evaluated showed no negative influence on the bond strength of dental adhesives to coronal dental substrates.

RESUMO

BACKGROUND: Limited data is available on variables influencing the survival of composite restorations in primary teeth. AIM: This retrospective university-based study assessed the survival and risk factors associated with failures of resin composite restorations performed in primary teeth. DESIGN: The sample was composed of 961 restorations from records of 337 patients (178 girls and 159 boys) attended in a university dental clinic. The restorations' longevity up to 48 months of follow-up was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P < 0.05). RESULTS: Mean survival time was 41.5 months (95% CI: 39.7-43.3), with 70.6% of the restorations surviving after 48 months of evaluation. The overall annual failure rate up to 48 months follow-up was 8.3%. Restorations placed in lower arch had lower survival rate than those in upper arch (HR: 1.82, 95% CI: 1.02-3.28). Restorations involving two or more surfaces had more risk of failure than restorations placed in cavities involving only one surface (HR: 2.55 95% CI: 1.34- 4.83). Girls had less risk of failure in their restorations (HR: 0.43, 95% CI: 0.19-0.96). CONCLUSION: Individual and dental variables such as gender, arch type and number of restored surfaces were associated with failure of composite restorations performed in children under daily life clinical environment.

RESUMO

PURPOSE: To examine the influence of phosphoric acid containing chlorhexidine on the dentin bond stability of a universal and a 2-step etch-and-rinse adhesive. MATERIALS AND METHODS: Eighty sound bovine incisors were randomly assigned to 8 groups (n = 10) according to: phosphoric acid (37% phosphoric acid [CTR] or 37% phosphoric acid with 2% chlorhexidine [CHX]); adhesive (Scotchbond Universal Adhesive [SBU]or Adper Single Bond 2 [SB2]); and water storage time (24 h and 6 months). Both acids and adhesives were applied to flat dentin surfaces (following manufacturer's instructions) upon which composite cylinders were built up (0.72 mm2). After storage in distilled water at 37°C for 24 h or 6 months, the composite cylinders were submitted to microshear bond strength (µSBS) testing. Bond strength data (MPa) were analyzed using three-way ANOVA and post-hoc Tukey's test (α = 5%). RESULTS: The interaction among factors was significant (p = 0.012). Both adhesives showed similar 24-h bond strengths regardless of the phosphoric acid. After 6 months, similar values were found for both materials when control phosphoric acid was used, but CHX phosphoric acid produced statistically significantly lower bond strengths for SBU. SB2 bond strength was not affected by acid type. CONCLUSION: Phosphoric acid containing chlorhexidine induced premature bond strength degradation of Scotchbond Universal Adhesive.

RESUMO

PURPOSE: The purpose of this clinical retrospective study was to assess survival and risk factors associated with failures of resin composite restorations placed in patients with early childhood caries. METHODS: Seventy-eight restorations in primary teeth from records of 24 high caries risk children were included in the study. The restorations' longevity up to 30 months of follow-up was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P<0.05). RESULTS: Mean survival time was 26 months (95 percent confidence interval = 24.5 to 26.7). The survival of the restorations reached 34.8 percent up to 30 months, with an overall annual failure rate of 20 percent. Restorations involving two or more surfaces had 2.50 times more risk of failure than restorations involving single surface (P=0.03). Restorations performed in vital teeth had a lower risk of failure than those performed in teeth that underwent pulp intervention (hazard ratio equals 0.25; 95 percent confidence interval =0.10 to 0.65; P=0.00). Patients with a plaque index more than 20 percent had 3.63 times more risk of failure in their restorations (P=0.01). CONCLUSION: Clinical variables, such as the number of restored surfaces, pulp therapy, and poor biofilm control, may affect the survival of composite restorations performed in patients with early childhood caries.

RESUMO

O presente estudo propõe um método para o ensino de detecção e avaliação de lesões de cárie, utilizando o Sistema Internacional de Avaliação e Detecção de Cárie (ICDAS) como ferramenta auxiliar. Sessenta e dois estudantes do quarto ano do curso de graduação em Odontologia da Universidade de São Paulo foram submetidos a três atividades de treinamento para uso do ICDAS, aplicadas em diferentes momentos: aula teórica convencional, atividade com projeção de imagens e atividade prática-laboratorial com dentes extraídos. Os estudantes responderam a questionários, antes e após as atividades, para avaliação do conhecimento e da percepção sobre as mesmas. Também foi realizada avaliação prática, com avaliação de dentes extraídos. Após os exercícios laboratoriais, a média de respostas corretas para questões conceituais aumentou significativamente e se manteve até o final da atividade laboratorial. Quem acreditava estar bem preparado no início da atividade teve 3 vezes mais chances de alcançar nota acima de 5 no segundo momento da atividade prática-laboratorial (OR=3,1; 95% IC=1,0 ­ 9,1). Concluiu-se que a atividade prática-laboratorial contribui para o aprendizado de estudantes de graduação na detecção de lesões cárie, inclusive sanando dúvidas conceituais que possam existir após a aula teórica. Todavia, a percepção do estudante pode não ser impactada pela atividade (AU).


The present study proposes a method for the teaching of the detection and evaluation of caries lesions, using the International Caries Detection and Assessment System (ICDAS) as an auxiliary tool. Sixty-two students in the fourth year of the undergraduate course in Dentistry of the University of São Paulo underwent three training activities for the use of the ICDAS, applied in different moments: regular theoretical class, activity with images projection and practicallaboratory activity. The students answered questionnaires, before and after the activities, to evaluate the knowledge and the perception about them. A practical evaluation was also performed, with evaluation of extracted teeth. After the laboratory exercises, the mean number of correct answers to conceptual questions increased significantly and remained until the end of the laboratory activity. Those who believed to be well prepared at the beginning of the activity had three times more chances to reach a score above 5 in the second moment of the practicallaboratory activity (OR = 3.1; 95% CI = 1.0 - 9.1). It was concluded that the practicallaboratory activity contributes to the learning of undergraduate students in the detection of caries lesions, including healing conceptual doubts that may exist after the theoretical class. However, the student's perception may not be impacted by the activity (AU).

RESUMO

Aim: The aim of this study is to evaluate the impact of dentin condition on bond strength of multi-mode adhesive systems (MMAS) to sound and artificially induced caries-affected dentin (CAD). Methods: Flat dentin surfaces of 112 bovine incisors were assigned to 16 subgroups (n = 7) according to the substrate condition (sound and CAD- pH-cycling for 14 days); adhesive systems (Scotchbond Universal, All-Bond Universal, Prime and Bond Elect, Adper Single Bond Plus and Clearfil SE Bond) and etching strategy (etch-and-rinse and self-etch). All systems were applied according to the manufacturer's instructions, and resin composite restorations were built. After 24 h of water storage, specimens were sectioned (0.8 mm2) and submitted to the microtensile test. Statistical Analysis: Data (MPa) were analyzed using three-way analysis of variance and Tukey's test (α = 0.05). Results: MMAS presented similar bond strength values, regardless etching strategy in each substrate condition. Bond strength values were lower when MMAS were applied to CAD in the etch-and-rinse strategy. Conclusion: The etching strategy did not influence the bond strength of MMAS to sound or CAD, considering each substrate separately. However, CAD impact negatively on bond strength of MMAS in etch-and rinse mode.

RESUMO

PURPOSE: To systematically review the literature on laboratory studies to determine whether the bond strength of adhesives to primary teeth is similar to that to permanent teeth. MATERIALS AND METHODS: This systematic review was conducted according to PRISMA and registered in PROSPERO (CRD42014015160). A comprehensive literature search was conducted considering in vitro studies published up to June 2015 in the PubMed/MEDLINE database, with no limit on year of publication. Two reviewers independently selected papers, extracted data and assessed the risk of bias. From 422 eligible studies, 42 were fully analyzed. Thirty-seven studies were ultimately included in the systematic review and meta-analysis. A global comparison was performed with a random-effects model at a significance level of p < 0.05, expressed by the difference of means between the groups. The mean bond strengths and standard deviations were tabulated and statistical analyses were conducted in RevMan 5.1 (The Cochrane Collaboration). RESULTS: There was a significant difference between groups, with permanent teeth presenting higher bond strength than primary teeth (p = 0.0005). When the enamel and dentin substrates were considered separately, dentin presented the same trend (p = 0.002), while for enamel there was no significant difference between the dentitions (p = 0.11). The majority of the studies had a high bias risk. CONCLUSION: Adhesives have higher bond strengths when applied to permanent than to primary teeth. This difference was also valid when the comparison was made between permanent and primary dentin.

RESUMO

This study aimed to compare the longevity of different conventional restorative materials placed in posterior primary teeth. This systematic review was conducted following the PRISMA statement and registered in PROSPERO (CRD42016035775). A comprehensive electronic search without date or language restrictions was performed in PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Scopus, Turning Research Into Practice (TRIP) and Clinical Trials databases up to January 2017, selecting randomized clinical trials that assessed the longevity of at least two different conventional restorative materials performed in primary molars. Seventeen studies were included in this systematic review. Pairwise and network meta-analyses were performed and relative risks and 95% confidence intervals (CI) calculated. Two reviewers independently selected the studies, extracted the data, and assessed the risk of bias. Restorations of primary molars with conventional glass ionomer cement showed increased risk of failure than compomer, resin-modified glass ionomer cement, amalgam, and composite resin. Risk of bias was low in most studies (45.38% of all items across studies). Pediatric dentists should avoid conventional glass ionomer cement for restoring primary molars.

RESUMO

Purpose: The purpose of this systematic review and meta-analysis was to assess the impact of dental caries on the oral health-related quality of life (OHRQoL) of preschool children. Methods: A literature search was undertaken through PubMed/MEDLINE, Scopus, and TRIP databases to verify available studies about the topic. Two reviewers independently selected the studies, extracted the data, and assessed the bias risk. Global meta-analysis was carried out comparing means and standard deviations of the OHRQoL overall score from preschool children with and without caries. Subgroup analysis was conducted using different cutoff points for caries: decayed, missing, or filled teeth (dmft) greater than or equal to one and greater than or equal to six. Results: From 597 potentially eligible studies, 63 were selected for full-text analysis and 29 were included in the review: 12 for quantitative analysis and 17 for qualitative analysis. Most studies were conducted in Brazil; Early Childhood Oral Health Impact Scale (ECOHIS) was the instrument used in most studies to evaluate OHRQoL. A dmft index at least of one was sufficient to negatively impact the OHRQoL of preschool children, although a higher cutoff point for caries augmented the difference between groups. Bias risk was low. Conclusions: Caries might be associated with negative impact on the oral health-related quality of life of preschool children, and this association tends to increase as the disease severity worsens.

RESUMO

This study aimed to systematically review the literature to address the question regarding the influence of different materials in the clinical and radiographic success of indirect pulp treatment in primary teeth. A literature search was carried out for articles published prior to January 2017 in PubMed/MEDLINE, CENTRAL, Scopus, TRIP and ClinicalTrials databases; relevant articles included randomized clinical trials that compared materials used for indirect pulp treatment in primary teeth. Two reviewers independently selected the studies and extracted the data. The effects of each material on the outcome (clinical and radiographic failures) were analyzed using a mixed treatment comparisons meta-analysis. The ranking of treatments according to their probability of being the best choice was also calculated. From 1,088 potentially eligible studies, 11 were selected for full-text analysis, and 4 were included in the meta-analysis. In all papers, calcium hydroxide liner was used as the control group versus an adhesive system, resin-modified glass ionomer cement or placebo. The follow-up period ranged from 24 to 48 months, with dropout rates of 0-25.7%. The material type did not significantly affect the risk of failure of the indirect pulp treatment. However, calcium hydroxide presented a higher probability of failure. In conclusion, there is no scientific evidence showing the superiority of any material used for indirect pulp treatment in primary teeth.

RESUMO

PURPOSE: This clinical retrospective study evaluated the survival and risk factors associated with failures of resin-based composite restorations in primary teeth. METHODS: A total of 212 restorations in primary teeth from records of 76 high caries-risk children were included. The restorations' longevity for up to six years of follow-up was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P<0.05). RESULTS: Mean survival time was 4.3 years (95 percent confidence interval (CI) equals 4.0 to 4.6). The survival of the restorations reached 35.3 percent, up to the sixth year, with an annual failure rate of 18.8 percent. Restorations placed in teeth with pulp treatment had a lower survival rate than those in vital teeth (hazard ratio [HR] equals 2.16, 95 percent CI equals 1.02 to 4.58). Patients who did not use standard fluoride toothpaste had more risk of failure in their restorations (HR equals 6.12, 95 percent CI equals 1.47 to 25.49). CONCLUSIONS: Composite restorations placed in high caries-risk children presented limited survival after six years of follow-up. Standard fluoride toothpaste use was a protection factor, while pulp treatment was a risk factor for restoration failure.
