Efficacy of a high concentration of nano silver fluoride in preventing caries: A randomized controlled trial.

Background: To investigate the effectiveness of a novel agent containing Nano Silver Fluoride 1500 (NSF 1500) and chitosan to inactivate carious lesions in children. Material and Methods: The study included eighty children. While both groups had fluoride dentifrice applied to their teeth, only the experimental group received treatment with the NSF 1500-ppm solution. The first and sixth-month interval examinations were conducted by two calibrated dentists (k = 0.85). Results: The NSF 1500 group had 69.2% of their teeth with arrested decay, while the control group had 24.1%. The difference was statistically significant (p 0.001), with a preventive fraction of 59.4%. The number needed to treat (NNT) was approximately two. The NSF 1500 formulation was more effective than toothbrushing alone with fluoridated dentifrice in preventing dental caries. Conclusions: The effectiveness of NSF 1500 is determined by the size and depth of the dental cavity. Its ability to arrest caries lesions was comparable to previously tested products, NSF 400 and NSF 600. Key words:Preventive dentistry, dental caries, nanoparticles.

An exploratory study of children with caries and its relationship to SARS-CoV-2.

This exploratory study investigated whether children with dental decay were more likely to have COVID-19 than those without caries. The children underwent dental inspection and blood collection for detection of SARS-CoV-2 antibodies. Fifty-four children aged 6 to 9 years participated in the survey, which was conducted between March and June 2020 in the municipality of Ipojuca, Pernambuco, Brazil. The diagnosis of caries was performed using the dmft and DMFT indices. Parents reported signs and symptoms of sickness in their children during this period. The serology test aimed to verify the immune response of the children to coronavirus by detecting IgM/IgG antibodies. Statistical analyses were performed at P < 0.05. The majority of the children presented caries (68.5%). Of the nine children who tested positive for COVID-19 (16.7%), eight presented IgG antibodies to the virus, and only one had IgG and IgM antibodies to SARS-CoV2. Children who tested positive for SARS-CoV-2 had a higher percentage of caries lesions than those who tested negative for SARS-CoV-2 (77.8% vs 65.9%), but this difference was not statistically significant.

Sense of Coherence and Oral Health in Children and Adolescents: a Scoping Review.

PURPOSE: The purpose of this study was to review the published studies that address the sense of coherence and its relationship with the oral health of children and adolescents. METHODS: This scoping review was structured according to the review method proposed by the Joanna Brigs Institute and conducted in accordance with PRISMA-ScR guidelines. The research was carried out in the following databases: Medline/ Pubmed®, Lilacs®, Scopus©, Cochrane©, Web of Science©, and Embase©. RESULTS: In this search, 358 studies were found, seven in Cochrane, 90 in PubMed®, three in Lilacs®, 101 in Web of Science©, 80 in Scopus©, and 77 in Embase©, totaling 24 publications. The studies were published in nine countries, most of them cross-sectional studies. CONCLUSIONS: Most studies have shown that a high sense of coherence (SOC) of both the caregiver and the child/adolescent is related to better oral health behaviors and a lower caries index. No conclusive information was observed on the relationship between SOC and periodontal diseases.

Non-Invasive Methods and the Use of Infiltrating Resins for the Control of Caries Progression in Deciduous Teeth: A Systematic Review and Meta-Analysis

ABSTRACT Objective: To evaluate the influence of non-invasive treatment associated with the use of infiltrating resin for managing caries lesions in primary teeth. Material and Methods: A systematic review was performed by selecting articles from 6 online databases, using a search algorithm and eligibility criteria for data extraction and data synthesis for the papers included. Clinical trials involving primary teeth with incipient caries lesions (1/2 of the enamel or 1/3 of the outer dentin) were included, presenting full text and answering the study's guiding question. This study used the RoB 2 tool for the risk of bias assessment and GRADE for certainty of evidence. Random effects meta-analyses were implemented, and lesion progression treatment effects were estimated through relative risk (RR) and associated 95% confidence intervals. Results: A total of 440 studies were found. After analyzing the inclusion criteria and removal of duplicates, eight studies were analyzed for quality evidence. Five of the eight studies included in this review contributed to the meta-analysis, all with some reflections regarding the risk of bias. Overall, the results of the meta-analysis showed that non-invasive treatment, when associated with the use of infiltrating resins, significantly reduced the risk of caries progression in relation to the treatment without this addition for follow-up periods ranging from 12 months to 2 years (RR 0.51 [0.40-0.65]). Conclusion: There is moderate certainty of evidence that the use of infiltrating resins associated with non-invasive treatments decreases the risk of caries progression in primary teeth with incipient caries lesions (1/2 of the enamel or 1/3 of the dentin outer) when combined with non-invasive control methods alone.

Oral manifestations in hospitalized children with COVID-19.

As the pandemic progressed, the incidence of viruses among children also increased. This study investigates the presence of oral lesions in hospitalized children by analyzing data collected from medical records of infants seen at the pediatric Infectious disease unit at the General Hospital of the University of Pernambuco, Recife, Brazil, from March to August 2020. This study includes children aged 0 to 12 years diagnosed with severe symptoms of COVID-19. The data describe the frequencies and percentages of categorical variables, expressed as mean, median, and standard deviation. The chi-square test evaluated the association of oral manifestations according to the presence of comorbidities. Of 89 children, 20.2% had oral manifestations, and mucositis was the most prevalent lesion (12.4%). Of the 18 children with oral manifestations, 12 did not present comorbidities, but 7.9% had multisystem inflammatory syndrome and 5.6% had Kawasaki disease. Results show that children with oral lesions had longer hospital stays. These findings indicate the need for further studies to clarify the relationship between the oral manifestations of COVID-19 in pediatric patients for screening of the virus by dentists.

Use of digital screens by adolescents and association on sleep quality: a systematic review.

This study aimed to analyze the influence of digital screen use on adolescents' quality of sleep. This systematic review was recorded on PROSPERO (CRD42020203403) and conducted according to PRISMA guidelines. Studies covering adolescents from 10 to 19 years were included without language or publication restrictions which answered the following guiding question: "Does the use of digital screen influence adolescents' quality sleep?". Article search included the following databases: (MEDLINE/PubMed), LILACS, SciELO, Scopus, EMBASE, Web of Science, IBECS, Cochrane Library, ClinicalTrials.gov, and Open Gray. The following descriptors were used: "Sleep Quality", "Screen Time", and "Adolescent". The Newcastle-Ottawa Scale (NOS) assessed the methodological quality of the cohort studies, and a modified NOS was used to assess the cross-sectional ones. In total, 2,268 articles were retrieved, of which 2,059 were selected for title and abstract reading, after duplicates were deleted. After this stage, 47 articles were selected for full reading, resulting in the 23 articles which compose this review. Excessive use of digital screens was associated with worse and shorter sleep, showing, as its main consequences, night awakenings, long sleep latency, and daytime sleepiness. The use of mobile phones before bedtime was associated with poor quality of sleep among adolescents. Our evaluation of the methodological quality of the chosen studies found seven to be poor and 16, moderate.

Sense of coherence and quality of life in adolescents with heart disease.

OBJECTIVE: The aim of this study was to assess the association between the Sense of Coherence (SoC) and Quality of Life (QoL) in adolescents with heart disease. METHODS: A cross-sectional study was carried out with 164 adolescents with congenital or valvular heart disease, aged between 10 and 18 years, treated in a referral center in the city of Recife - Brazil. The information collected contains census data, type of heart disease, economic status identified according to the Brazilian Criteria for Economic Classification (ABEP), as well as an evaluation of the SoC and the QoL. RESULTS: The SoC (50.09) and QoL (72.23) exhibited high average scores. The SoC was positively correlated with all dimensions of the QoL scale (p<0.001). The social and school dimensions, respectively, presented the highest and lowest scores. The linear regression analysis revealed that the SoC influenced the school and emotional dimensions. CONCLUSIONS: This study demonstrates that the SoC is a protective factor in the life of adolescents. This factor helps on the improvement of perception of QoL and on successfully dealing with daily adversities and chronic stress.

Viral symptoms in children and SARS-COV-2: information for pediatric dentists for the control of transmission.

The new coronavi rus, which has spread worldwide, has spiraled out of control in Brazil. The number of infected children has increased, and more Infants Special Care Units are needed to prevent deaths. This study aims to report the most common signs and symptoms in children infected by seasonal respiratory viruses and those infected by COVID-19. This knowledge is essential to educate pediatric dentists, who may contribute to identifying the difference in symptoms and notify the cases, thus preventing the spread of COVID-19. This study was carried out in a Family Health Center of Ipojuca, state of Pernambuco, Brazil, and included 54 children seen for dental emergency care. The parents provided information about the signs and symptoms of their children' s health conditions during the lockdown from March to July 2020. All children had a serological test to detect any exposure to the virus. Kolmogorov-Smirnov and Mann-Whitney tests were used to assess the distribution of the data and compare the quantitative variables between the groups. Among the study participants, 16.7% tested positive for COVID-19. The most prevalent symptoms were headache (38.9%), sneezing (35.2%), and fever (20.4%); six out of nine children with a positive test had symptoms after infection of an adult in the family. Children infected with COVID-19 showed similar clinical signs to those with negative results. Pediatric dentists should acquire knowledge to report on sick children and prevent the spread of the disease.

Quality of sleep and musculoskeletal pain in adolescents: observational study / Qualidade de sono e dores musculoesqueléticas em adolescentes: estudo observacional

ABSTRACT BACKGROUND AND OBJECTIVES: Musculoskeletal pain (MSP) is related to psychogenic factors and quality of sleep, showing that this triad is a biopsychosocial process. The aim of this study was to analyze an association between poor sleep quality and MSP in adolescents. METHODS: This study has an observational, cross-sectional character, in which 545 adolescents, aged between 11 and 15 years, were analyzed. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), the presence of MSP using the Nordic Musculoskeletal Questionnaire (NMQ), temporomandibular disorder using the Axis II of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and excessive daytime sleepiness using the Epworth Sleepiness Scale (ESS). Pearson Chi-square or Fishers Exact test were used to assess the association between two categorical variables. RESULTS: The prevalence of poor sleep quality, sleep disorders, MSP and excessive daytime sleepiness were, respectively, 66.8, 9.5, 87.5 and 30.5%. An association was observed between the quality of sleep and the number of hours of sleep per night [OR = 1.49; (1.01 to 2.21)], and between sleep disorders and MSP in the upper back [OR=1.9; (1.0 to 3.3)], and the wrists and hands [OR=2.8; (1.4 to 5.7)]. However, there was no association between sleep quality and MSP [OR=1.29; (0.76 to 2.17)]. CONCLUSION: An association was found between sleep disorders and MSP, as well as between the number of hours slept per night and quality of sleep.

Viral symptoms in children and SARS-COV-2: information for pediatric dentists for the control of transmission

Abstract: The new coronavi rus, which has spread worldwide, has spiraled out of control in Brazil. The number of infected children has increased, and more Infants Special Care Units are needed to prevent deaths. This study aims to report the most common signs and symptoms in children infected by seasonal respiratory viruses and those infected by COVID-19. This knowledge is essential to educate pediatric dentists, who may contribute to identifying the difference in symptoms and notify the cases, thus preventing the spread of COVID-19. This study was carried out in a Family Health Center of Ipojuca, state of Pernambuco, Brazil, and included 54 children seen for dental emergency care. The parents provided information about the signs and symptoms of their children' s health conditions during the lockdown from March to July 2020. All children had a serological test to detect any exposure to the virus. Kolmogorov-Smirnov and Mann-Whitney tests were used to assess the distribution of the data and compare the quantitative variables between the groups. Among the study participants, 16.7% tested positive for COVID-19. The most prevalent symptoms were headache (38.9%), sneezing (35.2%), and fever (20.4%); six out of nine children with a positive test had symptoms after infection of an adult in the family. Children infected with COVID-19 showed similar clinical signs to those with negative results. Pediatric dentists should acquire knowledge to report on sick children and prevent the spread of the disease.

Are exercises with or without occlusal splints more effective in the reduction of pain in patients with temporomandibular disorders of myogenic origin? A systematic review

Abstract Temporomandibular disorders (TMD) is a term used to describe a set of clinical conditions that may compromise the temporomandibular joint (TMJ) and masticatory muscles and/or associated structures, considered the most frequent cause of orofacial pain of non-dental origin. In recent years, many forms of physical therapy have been used in the treatment of TMD to reduce pain and improve the range of mandibular movement present in this impairment. Among these resources are kinesiotherapy (exercise), electrothermal and manual therapy, acupuncture, training posture, mobilizations, and biofeedback. Objectives To determine if exercises with or without occlusal splints are effective in reducing pain in patients with temporomandibular disorders (TMD) of myogenic origin. Methodology This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD 42019134244). Controlled trials published in PubMed, Scopus, and Cochrane Library following PRISMA guidelines up to April 2022 were randomized and included. The population above 18 years, which evaluated the effectiveness of exercise with or without occlusal splints in reducing pain in patients with TMD of myogenic origin, diagnosed through the Research Diagnostic Criteria for Temporomandibular Disorders, was also included. There was no restriction on the period of publication. Cochrane risk of bias analysis was performed. Results Of the five included articles, all showed a reduction of pain, but without significant differences between the interventions performed. Additionally, studies that evaluated the quality of life and mandibular movements showed a reduction in pain, but no significant differences between therapies. Conclusion The analyzed studies showed no difference in the improvement of pain, quality of life, and mandibular movements between the groups that performed only exercises or the associated treatments.

Prevalence of Dental Trauma in 1485 Brazilian Adolescents Aged Between 15 and 19 Years Old and Associated Factors.

PURPOSE: Investigate dental trauma among adolescents aged 15-19 years and associated factors. METHODS: The study was conducted in Recife, Brazil and the sample comprised 1485 adolescents of both sexes. The data was collected by clinical examination and interviews were conducted in-between classes by a single trained assessor. Two questionnaires (AUDIT and ASSIT 2.0) were used to investigate the involvement of adolescents with alcohol, tobacco and illicit drugs. The classification proposed by Andreasen was used to identify dental injuries. The sample size was calculated using 95% interval level. Pearson's chi-square test and Fisher's exact test were used to confirm the association between the variables. RESULTS: The prevalence of dental injuries was 17.8%. The main causes of trauma were playing with others (20.8%) and falls (25.4%). A statistically significant percentage of adolescents reported using illicit drugs (13.9%), 15.9% used tobacco and 56.8% used alcoholic beverages. However, no statistically significant difference between the consumption of this drugs and dental injuries (p >0.005) was found. CONCLUSION: The prevalence of dental trauma in adolescents was high, with no association with drugs use.

Enamel Defects in Deciduous Dentition and Their Association with the Occurrence of Adverse Effects from Pregnancy to Early Childhood.

PURPOSE: To verify the prevalence of developmental defects of enamel (DDE) in deciduous teeth and analyse the association with adverse events that occurred during pregnancy and early childhood. MATERIALS AND METHODS: In a cross-sectional study, 152 children with an average age of 3.57 ± 1.25 years were examined according to the criteria established by the DDE index. A previously validated questionnaire was given to mothers in order to obtain information regarding: calcium and vitamin D deficiency (measured in mothers); gestational diabetes; gestational undernutrition; weight at birth; neonatal hypoxia; and presence of asthma in early childhood. The clinical exam was conducted by a single examiner calibrated for visual exams (Kappa = 0.84), outdoors on patios of schools with children and examiner knee to knee. Pearson's chi-squared test and Fisher's Exact Test (p < 0.05) were used to determine statistically significant associations between the variables in study. The data were then analysed using a binary logistic regression regression. RESULTS: 26.3% of children exhibited DDE. It was possible to verify a statistically significant association between DDE and vitamin D deficiency (p < 0.01), calcium deficiency (p = 0.01), neonatal hypoxia (p = 0.026), and gestational diabetes (p = 0.04). The regression model allowed the conclusion that children who had neonatal hypoxia during childbirth, gestational diabetes or vitamin D deficiency during their gestation were 3.54, 12.47 and 6.40 more likely to exhibit signs of DDE, respectively. CONCLUSION: The prevalence of DDE was considered high and was associated with vitamin D and calcium deficiency during pregnancy, gestational diabetes, and neonatal hypoxia.

Caries experience in children and adolescents with Down Syndrome: A systematic review and meta-analysis.

AIM: This study aimed to perform a systematic review and meta-analysis comparing the prevalence of dental caries in non-syndromic children with children and adolescents with Down syndrome (DS). METHODS: The strategy included a search for articles in electronic databases (MEDLINE via PubMed, Cochrane Library, LILACS, and SciELO). The methods for assessment included the modified Newcastle-Ottawa scale, the methodological quality for cross-sectional studies, and a random-effects meta-analysis model. By obtaining the odds ratio, the tests of heterogeneity and sensitivity were performed. This study includes unpublished data from the cross-sectional study by Paiva et al. (2018), which was conducted in the city of Recife/PE. RESULTS: Twelve cross- section studies met the eligibility criteria and were included in the meta-analysis. Results indicated that children and adolescents with DS had lower caries experience when compared to the non-syndromic ones (95 % CI: 0.22-0.84). The results indicated that the seven studies were statistically significant (p < 0.00001). The risk of bias remained high given that the majority of the studies were cross-sectional reports. CONCLUSION: The results of this study fill the lack of knowledge and indicated that there is scientific evidence to suggest that children and adolescents with Down Syndrome have fewer caries than the non-syndromic group.

Oral Health Status and Treatment Needs Among Disabled Children in Recife, Brazil.

PURPOSE: The objective of the present study was to investigate oral health status and treatment needs of children with disabilities in Recife, Brazil. MATERIALS AND METHODS: A cross-sectional study was carried out in the six administrative districts of Recife. The sample consisted of 366 children with disabilities and age between 3 and 12 years. The oral health conditions investigated were dental caries (CPOD index and dmft index), gingival state (IPV and IGC index) and dental trauma. Data analysis involved descriptive statistics, Pearson's chi-square test, Fisher's exact test, and Poisson regression models. RESULTS: The prevalence of caries was 65% and was associated with age (p = 0.0027) and area of residence (p = 0.020). The prevalence of need for treatment was also 65%. The mean decayed, missing and filled teeth (DMFT)/DMFT index of the study population was 3.17/1.73. Their mean number of DMFT was 2.37, 0.55 and 0.25 for the deciduous dentition, as well as 1.56, 0.05 and 0.12 for the permanent dentition. Almost the entire sample (96.7%) had visible plaque, 77.3% had gingival bleeding and 27.6% had dental traumatism. CONCLUSION: Children with disabilities were found to have high rates of caries and gingivitis, as well as cumulative needs for preventive and curative treatment.

Prevalence of sleep-disordered breathing and associations with malocclusion in children.

STUDY OBJECTIVES: This study aimed to determine the prevalence of sleep-disordered breathing (SDB) and its association with malocclusion among children in Recife, Brazil. METHODS: This study included 390 children aged 7 to 8 years. The data comprised the measurement of body mass, orthodontic examination, and parental information required by the Sleep Disturbance Scale for Children. The statistics tools used were Pearson's chi-square test and the Lemeshow test. RESULTS: Positively screened for SDB was found in 33.3% of the children, and the association with overjet was P = .007 (odds ratio [OR], 95%, confidence interval [CI]: 1.93). The association with anterior open bite was P = .008 (OR, 95% CI: 2.03), and the association with posterior crossbite was P = .001 (OR, 95% CI: 2.89). This report was unable to indicate an association between body mass index and SDB. The multivariate logistic regression model revealed that the anterior open bite (P = .002; OR, 95% CI: 2.34) and posterior crossbite (P = .014; OR, 95% CI: 2.79) had an association with positively screened for SDB. CONCLUSIONS: The results of this study indicated that the prevalence of SDB was high and highly associated with malocclusion. Since posterior crossbite and anterior open bite were associated with positively screened for SDB, early diagnosis and intervention may prevent and minimize adverse effects of SDB on individuals lives.
