RESUMO

The aim of the present study was to evaluate the microtensile bond strength and the microleakage of a bulk-fill composite resin compared with a conventional incremental composite resin, in permanent molars and under cariogenic challenge using a Streptococcus mutans model. Permanent human third molars (n = 60) with an occlusal cavity of 5×3×2 mm were randomly allocated into four subgroups of restorative treatments: conventional composite resin with (n = 15) and without (n = 15) cariogenic challenge (Z350-E and Z350-C experimental and control groups, respectively), and bulk-fill composite resin with (n = 15) and without (n = 15) cariogenic challenge (Bulk Fill-E and Bulk Fill-C, respectively). Ten specimens from each subgroup were submitted to microtensile strength, and 5, to microleakage. The cariogenic challenge was conducted using the Streptococcus mutans strain (ATCC) for 7 days. The stickers obtained (1 × 1 × 2 mm) were submitted to a microtensile strength test, followed by classification of the fracture mode. Microleakage was performed using a scoring system. The data were analyzed by Kruskal-Wallis and Mann-Whitney tests (p < 0.05). Filtek Z350 XT resin presented higher microtensile bond strength than Bulk Fill resin without (19.02 ± 4.90 and 8.76 ± 3.94MPa, respectively; p < 0.001) and with cariogenic challenge (22.69 ± 7.86 and 13.31 ± 3.38MPa, respectively; p < 0.02). Z350-C and Bulk Fill-C resins presented a higher prevalence of mixed fractures (23 and 14%, respectively) in the specimens submitted to cariogenic challenge than those of the control groups, whereas microleakage was similar (p = 0.85). The conventional composite resin had higher microtensile bond strength than the bulk-fill resin, but both resin types had similar adhesion quality and microfiltration scores.

RESUMO

OBJECTIVES: The aim of the present systematic review was to evaluate if epoxy resin-based root canal sealers present superior push-out bond strength compared to calcium silicate-based root canal sealers. METHODS: The inclusion criteria consisted of in vitro studies that compared the push-out bond strength of epoxy resin-based and calcium silicate-based sealers. A systematic search was performed in the following databases for articles published until February 2018: PubMed, ScienceDirect, Scopus, Web of Science, and OpenGrey. The quality assessment and data extraction of the selected articles were performed. A meta-analysis of the pooled data and the subgroups according to the root thirds was carried out using the RevMan software (P < .05). RESULTS: The search resulted in 2292 studies. After the duplicate studies were removed and the title and abstract were read, 20 studies were selected and 17 were considered as having a low risk of bias. The pooled meta-analysis comparing epoxy resin-based (n = 467) and paste-to-paste calcium silicate-based root canal sealers (n = 467) demonstrated higher mean push-out bond strength values (P < .001) for the epoxy resin-based root canal sealers; the heterogeneity among studies was 85% (I2). The comparisons between epoxy resin-based (n = 358) and premixed ready-to-use calcium silicate-based root canal sealers (n = 358) also demonstrated a significant difference between the sealers (P < .05), with an I2 of 95%. The subgroup analysis showed that only in the middle third, were increased bond strength values for epoxy resin-based sealer observed (P < .001), with an I2 of 94%. CONCLUSIONS: The epoxy resin-based sealer demonstratedhigher push-out bond strength than paste-to-paste calcium silicate-based root canal sealer regardless of the root third assessed. In addition, the epoxy resin-based sealer exhibited increased push-out bond strength in comparison with premixed ready-to-use calcium silicate-based root canal sealer when evaluating the middle third.

RESUMO

PURPOSE: To evaluate the antimicrobial action and elemental composition of chlorhexidine (CHX) diacetate in acrylic resins based on PMMA (polymethyl methacrylate) in situ. In addition, ex vivo evaluation of the CHX release mechanism was performed over a 14-day period. METHODS: Three discs of PMMA incorporating CHX and three control discs were mounted on individual oral splints and exposed to the oral cavity of 32 participants for 24 hours. The antimicrobial activity was evaluated by the plate count method. In the second test, elemental analysis of the specimens (n = 10) was performed by X-ray fluorescence before and after use of the device. Chlorhexidine release over a 14-day period was evaluated ex vivo in saliva samples collected from five individuals through proton nuclear magnetic resonance spectroscopy ( ¹H NMR) (500 MHz). RESULTS: Bacterial adhesion, evaluated by the plate count method, did not differ between the experimental material and control. (P> 0.05) The presence of the CHX molecule was detected by X-ray fluorescence before and after insertion of discs containing CHX into the oral cavity of participants. With regard to release, CHX was detected in saliva samples for 14 days and highest during the first 24 hours. When partial least squares discriminant analysis (PLS-DA) was applied in ¹H NMR, we observed a greater difference between the test and control groups. CLINICAL SIGNIFICANCE: The sustained release of CHX from PMMA suggests that such materials may be convenient for reducing the development of biofilm on the surface of the material for use in dentures and temporary restorative materials.

RESUMO

Background: Our aim was to compare salivary levels of secretory immunoglobulin A (s-IgA) in children with early childhood caries (ECCG) and those who are caries-free (CFG) and verify these levels in a follow-up period after restorative treatment. Materials and methods: We selected 46 systemically healthy children in the complete primary dentition period, who were allocated into two groups: CFG (n = 23) and ECCG (dmf-s > 0; n = 23). Unstimulated whole saliva was obtained at baseline from both groups and during the follow-up period (7 days, 1, 2 and 3 months) in the ECCG group. The s-IgA was measured using an ELISA assay, and total protein was assessed using the Bradford method. We also evaluated the flow rate (mL/min), Streptococcus mutans and Lactobacillus spp. counting using selective media plaques. The data were submitted to statistical analysis using the software SPSS 20.0 (SPSS Inc, IL, USA) with a confidence interval set at 95%. Results: Salivary s-IgA levels were higher in baseline of ECCG than in CFG (p<0.05). No statistically significant differences were observed between s-IgA salivary levels at baseline and the evaluations after dental treatment in ECCG (p>0.05). However, we observed two different changes in s-IgA levels among participants: one group presented s-IgA reduction, and the other group demonstrated its maintenance. It was shown that patients from the ECCG group who presented a reduction in s-IgA levels during follow-up also showed a decrease in Streptococcus mutans and Lactobacillus spp. count (p<0.05), in contrast to patients who did not present this reduction. The flow rate and total protein were similar between groups (p>0.05). Conclusions: The present data support the idea that children with early childhood caries present higher levels of s-IgA in saliva than caries-free children. The restorative dental treatment does not have a significant influence on salivary levels of this immunoglobulin during the follow-up period.

RESUMO

Objective: The objective of the present literature review tis o verify the success rates, as well as the predisposing factors, associated to success rates of dental autotransplant treatments in teeth with complete rhizogenesis. Methods: An electronic search was performed on PubMed database using MeSH terms and free terms. Initially, a total of 115 titles and abstracts. An additional study was identified as relevant after a search of reference lists. After eligibility criteria appliance, only 8 articles were selected. Results: In general, the included studies show high success rates, based on established parameters such as periodontal ligament maintenance, periapical healing and periodontal health. In addition, the selected studies pointed out that factors such as extraction and reimplantation protocols, the time of follow-up used in the study and the time in which the endodontic treatment of the transplanted element was performed, can affect the success rate of dental transplant therapy. Conclusion: According to the present literature review, it can be concluded that although there are still few studies of autotransplantation performed in patients with complete rhizogenesis, the technique has proven itself as a viable option with moderate success rate for replacement of lost dental elements.

RESUMO

This retrospective study aimed to evaluate the dental trauma profile in primary and permanent teeth from patients between 0 and 15 years old who attended the Faculty of Dentistry of the Federal University of Rio de Janeiro. Data regarding gender, age, trauma classification, tooth type, and affected tissues were obtained from dental records. The data were analyzed descriptively and by the χ2 test (p < 0.05). Data associated with 333 traumatized teeth (70% primary and 30% permanent teeth) were included. The mean ages of children with affected primary and permanent teeth were 3.35 ± 2.02 and 9.09 ± 2.43 years, respectively. Males presented more permanent teeth with trauma (64.4%) than primary ones (55.6%; p = 0.085). The upper central incisors, both primary (68.9%) and permanent (69.4%), were the teeth most commonly affected. Primary teeth showed a higher frequency (p < 0.001) of supportive tissue trauma (73.3%) and lower frequency (p = 0.001) of hard tissue trauma (40.7%) than those in permanent ones (51.5% and 60.6%, respectively). The most frequent trauma in the supportive tissue was subluxation (27.2%) and permanent lateral luxation (42.0%). In the hard tissues, permanent teeth presented a higher prevalence of trauma than primary ones (p = 0.001), however this difference was not statistical significant when each type of fracture injury was evaluated individually (p > 0.005). With affected primary teeth, there was a greater frequency of trauma in the gingival mucosa (31.0%; p = 0.022); in the permanent ones, traumatic lesions in the chin region were the most prevalent (20.8%; p = 0.009). Trauma was recurrent in 26.3% of primary teeth and in 20.2% permanent teeth. Therefore, primary and permanent teeth showed distinct trauma profiles, suggesting that distinct preventive and therapeutic approaches are needed for these two groups.

RESUMO

OBJECTIVES: This systematic review aimed to verify if there is difference in the longevity of minimally invasive techniques compared to the complete replacement for the treatment of defective direct restorations in permanent teeth. DATA: The data included randomized controlled clinical trials comparing the clinical performance of defective dental restorations treated by a complete replacement technique or minimally invasive techniques on permanent teeth. Evaluation of the risk of bias was performed using the Cochrane Collaboration common scheme for bias and the evidence was qualified using the GRADE tool. SOURCE: A comprehensive search was performed in the electronic databases: PubMed, Scopus, ISI Web of Science, The Cochrane Library, LILACS, BBO, SIGLE, followed by manual search in the reference lists of the included studies, without any restrictions. STUDY SELECTION: From 5554 retrieved studies, 10 met the eligibility criteria and were submitted to data extraction and quality assessment. The repair technique presented similar results to replacement and superior results when compared to sealing. In addition, refurbishment demonstrated to be a useful treatment for localized anatomical form defects. All the studies presented low risk of bias and high quality evidence for repair and refurbishment and moderate for the sealing technique. CONCLUSIONS: The direct restorations treated by the repair, seal and refurbishment techniques did not present a significant difference in clinical longevity in comparison to the replacement technique in permanent teeth with overall moderate quality of evidence. CLINICAL SIGNIFICANCE: The present findings demonstrated that the best treatment for defective restorations is conservative management. The evidence demonstrated here helps and encourages clinicians during the decision-making process. Moreover, it suggests not replacing imperfect restorations, but to managing them in a minimally invasive way, allowing the structure to be preserved.

RESUMO

Introduction: Many factors are associated with caries development in children, including the daily environment. Thinking that few studies evaluate oral condition in a full-time educational environment. Objective: identify the oral health conditions and risk factors for caries in children enrolled in a full-time educational program. Methods: Data were collected from parents and their children aged 3-12 years that were enrolled in the full-time educational program in Rio de Janeiro, Brazil. The parents answered a questionnaire with socio-demographic, oral hygiene, habits and diet information. The children underwent clinical examinations. The association between children's caries and: parents education level; socioeconomic status; dental biofilm; hypoplasia, gingival bleeding and malocclusion was performed (Chi-square or Fisher's exact tests; p<0.05). Results : Thirty-eight parents attended the interview. The predominant caregivers were mothers with a high school complete degree and belonging to low income family. From a sample of 350 children, 38 (7.27±2.22 years) were examined during nine months. Most of these children were girls (63.2%) in the mixed dentition (69%) and without caries (61.9%). According to the caries index (decayed, missing and filled teeth), the highest average was found in the primary dentition (dmf-t = 1.20±2.12) while in the permanent one the mean DMFT was 0.35±0.86. Conclusion: Biofilm, hypoplasia, gingival bleeding and malocclusion were not associated with caries (p>0.05). The socioeconomics determinants and the risk factors were not considered predisposing factors for caries, which suggest that educational programs of full-time study exert a positive influence on children's oral health.


Introdução: Muitos fatores estão associados ao desenvolvimento da cárie em crianças, incluindo o ambiente que estão inseridos. Poucos estudos avaliam a condição bucal em um ambiente educacional de tempo integral. Objetivo: identificar as condições de saúde bucal e os fatores de risco para cárie em crianças matriculadas em um programa educacional de tempo integral. Métodos: Os dados os pais e seus filhos de 3 a 12 anos que estavam matriculados no programa educacional de tempo integral no Rio de Janeiro, Brasil, foram coletados. Os pais responderam a um questionário com informações sociodemográficas, sobre higiene bucal, hábitos e dieta. As crianças foram submetidas a exames clínicos. Foram realizadas análises sobre possíveis associações entre cárie infantil e escolaridade dos pais; status socioeconômico; biofilme dentário; hipoplasia, sangramento gengival e maloclusão (teste do qui-quadrado ou exato de Fisher; p <0,05). Resultados: Trinta e oito pais participaram da entrevista. Os cuidadores predominantes foram mães, em sua maioria com ensino médio completo e pertencentes à família de baixa renda. A amostra foi constituída por 350 crianças, 38 (7,27 ± 2,22 anos) que foram examinadas durante nove meses. A maioria das crianças era do sexo feminino (63,2%) na dentição mista (69%) e sem cárie (61,9%). De acordo com o índice de cárie (dentes cariados, ausentes e preenchidos), a maior média foi encontrada na dentição decídua (dmf-t = 1,20 ± 2,12) enquanto na permanente a média do CPOD foi de 0,35 ± 0,86. Conclusão: Biofilme, hipoplasia, sangramento gengival e má oclusão não foram associados à cárie (p> 0,05). Os determinantes socioeconômicos e os demais fatores de risco não foram considerados fatores predisponentes para a cárie, sugerindo que os programas educacionais de tempo integral exercem influência positiva na saúde bucal das crianças.

RESUMO

BACKGROUND: Toothpaste manufacturers encourage through aggressive marketing strategies the overconsumption of fluoridated dentifrices. There are conflicting results regarding fluoride intake from toothpastes in children. AIM: The aim of this systematic review and meta-analysis was to determine whether dentifrice flavour increases fluoride ingestion by children. DESIGN: We included clinical trials on children that evaluated the use of flavoured dentifrice - FD vs regular dentifrice - RD to identify the fluoride intake. An electronic search was performed in PubMed, Web of Science, Scopus, The Cochrane Library, LILACS/BBO, and grey literature followed by manual search. The methodological quality of the studies was assessed using the Cochrane Collaboration common scheme for bias and ROBINS-I tool. Data were analysed in subgroups such as low (G1) and ordinary (G2) fluoride concentrations of dentifrices. We carried out heterogeneity and sensitive analyses. RESULTS: For G1, the fluoride intake from RD was significantly higher than from FD [standardised mean difference = -2.57 (-3.26, -1.89), P < 0.00001]. For G2, the fluoride ingestion from RD was significantly higher than from FD [mean difference = -0.00 (-0.00, -0.00), P = 0.02]. CONCLUSIONS: There is evidence to support the null hypothesis that flavouring from dentifrice does not increase fluoride intake in young children.

RESUMO

PURPOSE: The aim of this systematic review and meta-analysis is to answer the focused question: Does the application of phosphoric acid, Er:YAG laser and air abrasion enamel conditioning methods previous to the oclusal sealant application in human permanent molars influence the microleakage? STUDY DESIGN: A literature research was carried out in the Pubmed Medline, Web of Science, Scopus and Cochrane databases using with the MeSH terms and keyword search strategy. A supplemental hand search of the references of retrieved articles was also performed. Inclusion criteria comprised ex vivo studies (extracted teeth) with permanent human teeth that used chemical (phosphoric acid) or mechanical (Er:YAG laser and air abrasion) conditioning methods previous the sealant application. The studies should evaluate microleakage as an outcome. Meta-analysis pooled plot were obtained comparing the microleakage after pre-treatment with phosphoric acid, Er:YAG and air abrasion enamel conditioning for sealant application using RevMan software. RESULTS: The search resulted in 164 articles, 55 records were excluded because they were duplicated. The analysis of titles and abstracts resulted in the exclusion of 105 studies. Four studies were included in the systematic review and the meta-analysis. According to the risk of bias evaluation, the four studies were considered low risk of bias. The meta-analysis showed that phosphoric acid had lower microleakage than Er:YAG laser (p < 0.001) and air abrasion (p < 0.001), with heterogeinity of I2 = 0% and I2 = 71%, respectively. It was not found statistical difference when compared phosphoric acid and phosphoric acid combined with Er:YAG laser and air abrasion (p > 0.05). CONCLUSION: The evidence supports that the pretreatment with phosphoric acid leads lower microleakage in oclusal sealants than Er:YAG laser and air abrasion.

RESUMO

Objective: To investigate the effect of a pediatric syrup containing Amoxicillin on resin-based on the surfaces of resin-based materials under pH cycling. Material and Methods: Cylindrical samples (n=60) of a compomer (Freedom) and a microhybrid composite (TPH Spectrum) were prepared following the manufacturer's instructions. The specimens were divided into two groups and treated for 30min, twice a day, for 14 days with a pediatric syrup containing Amoxicillin, Amoxil™ 500mg/5ml (experimental group) or Distilled water (control group). During the 14 days, the samples were submitted to pH cycling (3h in demineralizing, 20h in remineralizing saliva, and 1h for treatment). The surface roughness was evaluated at baseline, on the 7th and 14th days of erosive challenge using a profilometer and illustrated by SEM. The data were statistically analyzed by one-way ANOVA, Tukey HSD and paired T- tests (p < 0.05). At baseline, the mean Ra TPH = mean Ra F (p > 0.05). Results: After 7 days, it was observed no erosion (p = 0.674) for THP Spectrum (0.19 Ra) and an increasing of Ra (p = 0.02) for Freedom (19.95 Ra). After 14 days, it was observed an increasing of Ra for both THP Spectrum (0.56 Ra) and for Freedom (3.44 Ra), demonstrating that the degradation was treatment and time-dependent (p < 0.001). The pediatric syrup containing Amoxicillin increased the surface roughness of the TPH Spectrum surface one and a half times (p = 0.003) and the surface roughness of Freedom was increased by more than two times (p < 0.001). SEM images showed different aspects of the surfaces of the two materials with a loss of integrity to both. Conclusion: The pediatric syrup containing Amoxicillin under pH cycling increased the roughness of the both tested resin-based restorative materials.

RESUMO

BACKGROUND/AIM: The association between trauma and caries is still controversial in the literature. The aim of this study was to evaluate the possible association between caries and dental trauma through a systematic review with meta-analysis. DESIGN: A systematic literature search was performed in PubMed, Lilacs, BBO, Scopus, Web of Science, Cochrane Library, and Open Grey databases. The MeSH terms used were 'Tooth injuries', 'Tooth fractures', 'Tooth avulsion', 'Tooth movement'; 'Dental caries'; 'DMF index'; and 'Tooth demineralization'. MeSH synonyms, related terms, and free terms were included. The inclusion criteria comprised clinical investigations of subjects with and without caries that had suffered dental trauma. Quality assessment and bias control were carried out. Meta-analysis was performed using the comprehensive meta-analysis software (version 3.2). Heterogeneity was assessed using the I2 index, and the odds ratio was also calculated (P < 0.05). RESULTS: From 1290 abstracts, seven met the inclusion criteria. All studies had high methodological quality and five were included in the meta-analysis. The results demonstrated a positive association (P < 0.001) between dental trauma and dental caries in permanent teeth [OR: 1.490, 95%, CI: 1.209-1.835]. However, for children with primary teeth, the results showed a negative association (P = 0.006) between dental trauma and caries [OR: 0.706, 95%, CI: 0.550-0.906]. CONCLUSIONS: The results demonstrated positive and negative association between the presence of caries and dental trauma in permanent and primary teeth, respectively.

RESUMO

This study aimed to perform a systematic review and meta-analysis to evaluate the effectiveness of chlorhexidine varnish on the reduction of caries incidence during fixed orthodontic treatment. The literature searches involved The Cochrane Library, Medline, Scopus, OpenSigle databases and manual searches. The search on OpenSigle did not produce any additional articles. Clinical studies conducted in patients with orthodontic fixed appliances that used professional application of chlorhexidine varnish were included. The effect-size was calculated and a meta-analysis was performed. From 182 abstracts, a total of six articles fulfilled the inclusion criteria. After reading the full articles, one was excluded because of lack of a control group. Three articles were used for continuous data analysis, and two articles were used for the dichotomous data analysis. The pooled meta-analysis with continuous data demonstrated chlorhexidine varnish effectiveness on caries reduction (p = 0.003), with a mean difference and confidence interval of -1.49 [-2.47, -0.51]. On the basis of the pooled meta-analysis of continuous data, we were able to conclude that professional application of chlorhexidine varnish is effective in caries incidence reduction during fixed orthodontic treatment.

RESUMO

The aim of this paper is to describe a rare case report of a pediatric patient with secondary Sjögren's syndrome (SSS). A 12-year-old female child was referred to the Pediatric Dentistry Clinic with the chief complaint of tooth pain, dry mouth, and tooth sensibility. The patient was submitted to orthodontic treatment prior to syndrome diagnosis. The clinical treatment consisted of the interruption of orthodontic treatment and restoring the oral condition with dental treatment and the use of artificial saliva in an innovative apparatus. Dental therapy involved the control of dental caries, periodontal disease, and opportunistic fungal infections and the use of fluoride-rich solutions. The present clinical case describes clinical and laboratory aspects of SSS in pediatric patients. The management of the oral findings promoted an improvement in the oral health status and quality of life of the child.

RESUMO

Objective:Toevaluate the knowledge of parents and guardians of school-age children about oral hygiene and diet in a shelter and in a higher education institution. Material and Methods:A study with 82 parents and guardians of school-age children in the Teresa de Jesus Shelter (ATJ; n = 47) and the Veiga de Almeida University (UVA; n = 35) was conducted. A questionnaire with objective questions about hygiene and diet was used. The data were compiled in a database and analyzed using the SPSS 20.0 software (SPSS Inc, Il, USA). Descriptive analysis of data was conducted and normality was verified using the Shapiro-Wilk test (p <0.05). Categorical variables were compared using the χ2 test (p <0.05). Results:The mean age of children at ATJ was 4.9 (± 2.5) and those at UVA was 7.1 (± 2.7) (p <0.01). There was no difference between groups in relation to age (p = 0.71) and educational level of parents and/or guardians (p = 0.93); however, parents of children at UVA showed higher income (p = 0.02). Parents of children at ATJ had more information on oral health care (p <0.01). Most of the ATJ group (98.7%) claimed that visiting the dentist is also an important factor for the prevention of oral diseases compared to the UVA group (25.7) (p <0.01) and showed higher number of visits to the dentist (p = 0.03). ATJ parents associate more bacteria (p <0.01) and not going to the dentist as causal factors for dental caries (p = 0.03).Conclusion:Despite the worse socio-economic conditions, parents and guardians of children at ATJ had more knowledge about oral hygiene and diet than respondents of UVA. It is likely that the educational activities held at ATJ have influenced this result

RESUMO

Abstract This study aimed to perform a systematic review and meta-analysis to evaluate the effectiveness of chlorhexidine varnish on the reduction of caries incidence during fixed orthodontic treatment. The literature searches involved The Cochrane Library, Medline, Scopus, OpenSigle databases and manual searches. The search on OpenSigle did not produce any additional articles. Clinical studies conducted in patients with orthodontic fixed appliances that used professional application of chlorhexidine varnish were included. The effect-size was calculated and a meta-analysis was performed. From 182 abstracts, a total of six articles fulfilled the inclusion criteria. After reading the full articles, one was excluded because of lack of a control group. Three articles were used for continuous data analysis, and two articles were used for the dichotomous data analysis. The pooled meta-analysis with continuous data demonstrated chlorhexidine varnish effectiveness on caries reduction (p = 0.003), with a mean difference and confidence interval of −1.49 [−2.47, −0.51]. On the basis of the pooled meta-analysis of continuous data, we were able to conclude that professional application of chlorhexidine varnish is effective in caries incidence reduction during fixed orthodontic treatment.

RESUMO

Regional odontodysplasia is a rare and significant dental malformation. The present report describes an unexpected radiographic finding of rare tooth developmental anomaly and conservative management of primary teeth with in a child in mixed dentition. A 5-year-old healthy girl was referred to the Pediatric Dental Clinic due to pain and periapical radiograph exam showed teeth with abnormal large pulp chambers and a thin enamel and dentin of the primary incisors and canine and abnormal germs of the permanent successors teeth, with 'ghost-like' appearance. In addition, no root formation or only an insignificant amount was visible, characterizing regional odontodysplasia. At 10 years old, the treatment plan consisted of rehabilitation with a provisory partial resinous fixed prosthesis until implant surgery. The girl is still being followed up periodically.


A odontodisplasia regional é uma importante e rara malformação dental. O presente relato descreve um achado radiográfico inesperado de uma anomalia de desenvolvimento rara e seu manejo conservador em uma criança em dentição mista. Uma menina de 5 anos de idade, saudável, foi encaminhada à Clínica de Odontopediatria devido à dor. O exame radiográfico periapical mostrou os elementos dentários com câmaras pulpares amplas e uma fina camada de esmalte e dentina nos incisivos decíduos e anomalia nos germes dentários dos caninos permanentes sucessores, com aparência de 'dente-fantasma'. Além disso, não havia formação de raízes ou apenas uma quantidade insignificante era visível, caracterizando a odontodisplasia regional. Aos 10 anos, o plano de tratamento consistiu na reabilitação provisória por meio de uma prótese parcial fixa de resina até a cirurgia de implante ser possível. A criança, ainda, se encontra em acompanhamento periódico.

RESUMO

OBJECTIVES: A systematic review was performed with the aim of determining whether there is scientific evidence of the transmission of Streptococcus mutans from mother to child. DATA: The eligibility criteria, based on the PECO strategy, were the following: observational human studies whose subjects were mother and child pairs (P) contaminated by S. mutans (E); comparison according to the presence or absence of S. mutans (C); and whether there is transmission (O). The qualitative analysis was performed by assessing the risk of bias of the included studies, while quantitative synthesis was performed through comprehensive Meta-Analysis software (p<0.05). SOURCES: Two reviewers performed the database search of studies published between January 1950 and May 2014. The strategy included observational studies that assessed the vertical transmission of S. mutans from mothers to children through analyzing genetic strains. STUDY SELECTION: It was found 166 non-duplicated studies. However, after reviewing the articles in full and applying the eligibility criteria, 36 papers were selected for qualitative analysis and 19 for quantitative analysis. The cumulative meta-analysis demonstrated vertical transmission of S. mutans from mother to child (p<0.001). CONCLUSIONS: The present systematic review and meta-analysis demonstrated evidence of vertical transmission of S. mutans from mother to child because there was an association between S. mutans n mothers and their respective children. CLINICAL SIGNIFICANCE: The knowledge of the S. mutans strains is important because the virulence of the microorganisms is varied; also, the virulence affects the dental caries evolution rate, being more or less aggressive.

RESUMO

Objective: to evaluate the knowledge of parents and guardians of school-age children about oral hygiene and diet in a shelter and in a higher education institution. Material and Methods: a study with 82 parents and guardians of school-age children in the Teresa de Jesus Shelter (ATJ; n = 47) and the Veiga de Almeida University (UVA; n = 35) was conducted. A questionnaire with objective questions about hygiene and diet was used. The data were compiled in a database and analyzed using the SPSS 20.0 software (SPSS Inc, Il, USA). Descriptive analysis of data was conducted and normality was verified using the Shapiro-Wilk test (p <0.05). Categorical variables were compared using the χ2 test (p <0.05). Results: the mean age of children at ATJ was 4.9 (ñ 2.5) and those at UVA was 7.1 (ñ 2.7) (p <0.01). There was no difference between groups in relation to age (p = 0.71) and educational level of parents and/or guardians (p = 0.93); however, parents of children at UVA showed higher income (p = 0.02). Parents of children at ATJ had more information on oral health care (p <0.01). Most of the ATJ group (98.7%) claimed that visiting the dentist is also an important factor for the prevention of oral diseases compared to the UVA group (25.7) (p <0.01) and showed higher number of visits to the dentist (p = 0.03). ATJ parents associate more bacteria (p <0.01) and not going to the dentist as causal factors for dental caries (p = 0.03). Conclusion: despite the worse socio-economic conditions, parents and guardians of children at ATJ had more knowledge about oral hygiene and diet than respondents of UVA. It is likely that the educational activities held at ATJ have influenced this result.

RESUMO

This study evaluated the ion exchange at the material/enamel interface and the preventive effect of restorative materials submitted to cariogenic challenge against white spot. Restorations in enamel/dentin of bovine teeth were performed with composite resin (Filtek™ Z250 - control group) and glass-ionomers cements - GICs (Ionomaster R™ and Fuji IX™ - experimental groups). Samples were grouped and submitted to neutral saliva (n = 15) or pH-cycling regimen (n = 15). After eight days of pH cycling, material/enamel interfaces were analyzed by EDX in order to determine the differences (p < 0.05) in ionic exchange (Ca, P, F, Al, Sr, and Si) between restorative materials and teeth. In addition, enamel white spot lesion formation was evaluated macroscopically (p < 0.05). Sr content was higher in the enamel of the control group (p > 0.05) versus the experimental groups. Ca and P content were higher in enamel than in restorative materials. After pH cycling, the GIC enamel bulk showed a significantly higher Sr content compared with the composite resin (p < 0.05). Filtek™ Z250 was not able to prevent white spot formation around restorations in comparison with Ionomaster R™ (p < 0.001) and Fuji IX™ (p = 0.004). GICs reduced white spot formation and presented a preventive effect (p = 0.051). GICs presented a greater percentage of fluoride, aluminum, and strontium, and proved effective in white spot lesion prevention around restorations.
