RESUMO

A erupção dentária é definida como a movimentação dos dentes em desenvolvimento para emergir através dos tecidos moles da maxila e da mandíbula. O primeiro dente decíduo geralmente irrompe na cavidade bucal em um intervalo entre quatro e dez meses de idade e manifestações locais e sistêmicas associadas à erupção são observadas e relatadas por pais de bebês que passam pelo processo. Deste modo, este trabalho busca revisar e analisar a literatura em relação à percepção dos pais sobre os sinais e sintomas observados durante o processo de erupção dentária em bebês. Foi realizada uma revisão integrativa da literatura, buscando por artigos indexados nas bases eletrônicas de dados PubMed e Portal BVS. Ao final, foram selecionados 16 artigos científicos, sendo em sua maioria estudos com delineamento transversal (n: 11). Apenas dois estudos foram realizados no Brasil, sendo a Índia (n: 4) o país com maior número de artigos incluídos. Os sinais e sintomas mais relatados pelos pais foram febre (n: 16), perda de apetite (n: 13) e aumento da salivação (n: 12). Os estudos analisados apresentaram limitações, como a falta de padronização dos questionários direcionados aos pais. Compreende-se, desta forma, que mais estudos com populações variadas, amostras maiores e questionários padronizados são necessários.

Dental eruption is defined as the movement of developing teeth to emerge through the soft tissues of the maxilla and mandible. The first deciduous tooth usually erupts into the oral cavity between the fourth and tenth month of age. During this time, local and systemic manifestations are observed and reported by parents of babies who undergo the process. Thus, this stud seeks to review and analyze the literature regarding the perception of parents about the signs and symptoms observed during the process of tooth eruption in babies. An integrative literature review was performed, searching for articles indexed in PubMed and Portal BVS electronic databases. Sixteen papers were selected, mostly of which were cross-sectional studies (n: 11). Only two studies were carried out in Brazil, with India (n: 4) being the country with the highest number of articles included. The most reported signs and symptoms were fever (n: 16), loss of appetite (n: 13) and increased salivation (n: 12). The analyzed studies had limitations, such as the lack of standardization of the questionnaires addressed to parents. We conclude more studies with varied populations, larger samples and standardized questionnaires are needed.

RESUMO

Objective: The aim of this study was to determine the prevalence of extrinsic black pigmentation in primary dentition and its relationship with dental caries in children aged 3 to 5 years. Materials and methods: The study design was descriptive, prospective, cross-sectional and observational; The sample of the present study consisted of 79 children who were receiving treatment with ferrous sulfate, who underwent a clinical examination and odontogram. To determine the presence of extrinsic black pigmentation, the Shourie classification was used. Results: A low prevalence of extrinsic pigmentation of 7.6% was found, and children with extrinsic pigmentation had a Ceod of 9.83+-3.601, while those children without the presence of pigmentations had a Ceod of 4.60+-3.248. Conclusions: A significant relationship was found between the Ceod index and extrinsic black pigmentation (p<0.001).

RESUMO

Traumatic dental injuries (TDI) are common in children due learning to walk and lack of balance that leads to falls. Luxation is the trauma that occurs most frequently in the deciduous, being that the intrusive and the avulsive are the ones that cause more damage to the permanent successors. The potential to cause disturbances to the developing permanent germ is high due to anatomical proximity and depends on age, direction of intrusion, severity and treatment. The consequences to the permanent range from hypocalcifications of enamel to retention of the permanent germ. In this case, the developmental disturbance of the tooth 21 presenting with acute dentoalveolar abscess was a result of a three-degree intrusive luxation of the deciduous predecessor. The tooth 61 was misdiagnosed initially as avulsion, but it was a total intrusion as uncovered after a radiographic examination that showed an image suggestive of the presence of the deciduous tooth. The deciduous was extracted along with his permanent successor through outpatient procedure under antibiotic coverage and local anesthesia. The macro and microscopic analysis of the piece evidenced the presence of elements 21 and 61 closely united, as well as alterations provoked in both. There was remission of the infectious process and after 7 days it was verified the correct healing of the surgical wound. The radical outcome of this case emphasizes the relevance of appropriate clinical support as soon as possible in all TDI.

RESUMO

BACKGROUND: The present study aimed to assess the frequency and variation of 13 nonmetric dental crown traits (NDCT) in permanent and primary molars in German orthodontic patients. METHODS: Dental records from orthodontic patients were screened and evaluated. First and second permanent and primary upper and lower molars (from left and right sides) were assessed. Teeth with cavitated dental caries, occlusal wear, restorations and obvious dental deformities were not evaluated. The NDCT for permanent molars were identified and scored according to the odontoscopic system developed by Arizona State University Dental Anthropology System (ASUDAS). The NDCT for primary molars were identified and scored according to ASUDAS, Hanihara's method and Sciulli's method. The χ2 test was used to investigate side preference and sexual dimorphism at a significance level of p ≤ 0.050. RESULTS: A total of 163 orthodontic patients (82 males and 81 females) aged 8-14 years were included. A sexual dimorphism was observed for the hypocone in first upper permanent molar (p = 0.041). The protostylid was observed in lower permanent molars (range 2.1-10%). Males presented more hypoconulid than females (p = 0.019). Only females presented the distal trigonid crest in lower first permanent molars (p = 0.002). The most common groove pattern in primary molars was Y; male presented more Y grade than females in the lower second primary molar (p = 0.039). Asymmetry was observed in some traits, ranging from 0 to 100%. CONCLUSION: The present study showed the frequency of NDCT of molars in German orthodontic patients and demonstrated that some traits present sexual dimorphism.

RESUMO

The objective of this work was to estimate the prevalence and severity of erosive tooth wear (ETW), and to identify risk indicators of deciduous dentition of a group of schoolchildren from public schools in Tlalnepantla de Baz, State of Mexico. A cross-sectional study was carried out in 352 schoolchildren from 5 to 7 years old. The severity of the ETW was evaluated using the Basic Erosive Wear Examination (BEWE). Risk indicators were evaluated through a survey which included food and beverage consumption, consumption habits, vitamin C consumption, gastroesophageal reflux, heartburn, belching, xerostomia, vomiting and teeth grinding. Multinomial logistic regression models were fitted. The prevalence of ETW was 99.7% (n = 351). Regarding severity, 46.6% were at a null/mild level, 27.3% moderate, and 26.1% severe. Males were more likely to present severe ETW (odds ratio (OR) = 2.23, 95% confidence interval (CI), 1.27-3.93; p = 0.005). The risk indicators for the severity of ETW were the frequent consumption of citrus fruits (OR = 2.09, 95% CI, 1.12-3.89; p = 0.021), fruit juice (OR = 1.99, 95% CI, 1.06-3.75; p = 0.033), processed beverages (OR = 2.15, 95% CI, 1.23-3.78; p = 0.008) and hot sauce (OR = 1.82, 95% CI, 1.03-3.20; p = 0.036). The prevalence of ETW in the deciduous dentition was very high (99.7%) and ~1/3 for severe ETW. The dietary factors associated with severe ETW are part of the regular consumption of Mexican school-age children, which impact their oral health condition. It is important to establish intervention strategies from the infant stage, focused on both children and their caregivers.

RESUMO

Temperate fruit and nut crops require distinctive cold and warm seasons to meet their physiological requirements and progress through their phenological stages. Consequently, they have been traditionally cultivated in warm temperate climate regions characterized by dry-summer and wet-winter seasons. However, fruit and nut production in these areas faces new challenging conditions due to increasingly severe and erratic weather patterns caused by climate change. This review represents an effort towards identifying the current state of knowledge, key challenges, and gaps that emerge from studies of climate change effects on fruit and nut crops produced in warm temperate climates. Following the PRISMA methodology for systematic reviews, we analyzed 403 articles published between 2000 and 2023 that met the defined eligibility criteria. A 44-fold increase in the number of publications during the last two decades reflects a growing interest in research related to both a better understanding of the effects of climate anomalies on temperate fruit and nut production and the need to find strategies that allow this industry to adapt to current and future weather conditions while reducing its environmental impacts. In an extended analysis beyond the scope of the systematic review methodology, we classified the literature into six main areas of research, including responses to environmental conditions, water management, sustainable agriculture, breeding and genetics, prediction models, and production systems. Given the rapid expansion of climate change-related literature, our analysis provides valuable information for researchers, as it can help them identify aspects that are well understood, topics that remain unexplored, and urgent questions that need to be addressed in the future.

RESUMO

This paper evaluated the influence of different protocols of silver fluoride (SF) pretreatment of artificial carious lesions on the adhesive interface of composite resin restorations and remineralization of deciduous dentin compared to silver diamine fluoride (SDF). Sixty-four deciduous molar teeth were randomly divided into 8 groups (n = 8) according to the restoration time (immediately - IM; 30 days after SDF/SF treatment - 30 D) and treatment before restoration (SDF 38 %; SDF 38 % + potassium iodide - KI; SF 38 %; SF 38 % +KI). After SDF/SF application, teeth in the IM group were restored with self-etch universal adhesive system/composite resin. Samples in the 30D groups were stored in artificial saliva (37 °C) for 30 days before receiving the same restoring protocol. Beams were obtained from all groups and subjected to bond strength tests (µTBS), ultrastructural qualitative analysis (FEG) and mineral analysis (SEM/EDX; Micro-Raman spectroscopy). The µTBS data were subjected to three-factor ANOVA and multiple comparisons (Holm-Sidak method). Bond strength values (MPa) for IM groups were 16.9 ± 2.7 (SDF); 17.6 ± 3.5 (SDF + KI); 16.8 ± 5.5 (SF); 18.4 ± 4.1 (SF + KI); and 14.9 ± 4.2 (SDF); 16.0 ± 5.4 (SDF + KI); 14.1 ± 3.6(SF); 16.4 ± 5.4 (SF + KI) for 30D groups. Bond strength wasn't influenced by the moment of restoration (IM or 30D); the use of KI didn't alter adhesion characteristics; SDF/SF solutions resulted in similar adhesive strength; calcium and phosphate expressions were identified at the interfaces on IM and 30D moments. However, 30D presented qualitative increase in these ions, compatible with remineralization. It was concluded that the adhesion of composite resin restorations in artificial caries lesions of deciduous teeth treated with SDF (38 %) and SF (38 %) had similar effects in vitro; the use of KI or the moment when restorations were accomplished did not influence the adhesion and all tested protocols promoted remineralization of carious dentin.

RESUMO

PURPOSE: In recent years, minimal intervention procedures (MIPs) for treating dental caries in children have stood out as an innovative method. Nevertheless, the treatment decision should be based on scientific evidence, professional expertise, and parents' preference/acceptance. Evaluating the acceptance of MIPs by parents is an essential factor, but little information is available on what guides this preference. METHODS: This scoping review aims to synthesize the evidence on parents'/caregivers' acceptance of MIP for managing cavitated caries lesions in children. A search was performed in the PubMed, Cochrane Library, Lilacs and Google Scholar databases with no restriction on date or language. RESULTS: A total of 19 articles were selected (6 clinical trials, 1 longitudinal and 12 cross-sectional studies). The application of silver diamino fluoride (SDF) was the most commonly evaluated procedure (n = 17), followed by the atraumatic restorative technique (ART) and the Hall Technique (HT). The acceptance of MIPs ranged from 1.4% to 100%, and the application of SDF was better accepted in posterior teeth and in uncooperative children. ART had better aesthetic acceptance than HT. CONCLUSION: Application of SDF, Hall Technique and ART was well accepted by parents/caregivers. However, a gap remains in the literature regarding the acceptance of other procedures. Therefore, further studies in this area will contribute toward a better understanding of the opinion of parents/caregivers, and thus improve caries lesion management in children.

RESUMO

Abstract This study was a randomized controlled clinical trial with two parallel arms and the objective was to compare the survival of resin modified glass ionomer (RMGIC) restorations in primary teeth using rubber dam or cotton roll isolation after a 30-month follow-up period. Ninety-two children (mean age 6.8 ± 1.37) and 200 primary molars with occlusal or occluso-proximal cavitated dentin caries lesions were randomly assigned into two groups: cotton rolls and rubber dam. All lesions were restored using RMGIC (RIVA Light Cure) after selective caries removal. Restorative failure and lesion arrestment were evaluated by two independent, trained, and calibrated examiners through clinical and radiographic examinations. The Kaplan-Meier test was used to assess the survival of restorations and Cox regression was used to assess the association of risk factors with restorative failure. There was no significant difference in survival rates between groups (p = 0.17). Older age (HR = 2.81 [95%CI: 1.47-5.44]) and higher rate of gingival bleeding (HR = 0.47 [95%CI: 0.23-0.99]) were associated with restorative failure. No patient had painful symptoms, pulp outcomes, or radiographic changes compatible with lesion progression. The use of rubber dam isolation did not increase the survival rate of occlusal and occluso-proximal restorations using RMGIC in primary molars after 30 months of follow-up. Since the survival is not influenced by the type of isolation, the professional can safely choose the appropriate technique for each case, considering his experience and preferences, as well as those of the patient.

RESUMO

ABSTRACT Objective: This study aimed to evaluate occlusion development after premature loss or extraction of deciduous anterior teeth, by means of a prospective cohort study. Methods: Fifteen infants and children aged 1 to 5 years old were longitudinally assessed (with loss or extraction of deciduous anterior teeth [n = 9], and without tooth losses [n = 6]). Photographs and dental casts at the baseline and after 24 months of follow-up were performed. Dental casts were scanned, and linear measurements were made on the digitalized models (missing tooth space, arch perimeter, arch length, arch width, intercanine length and intercanine width). The t-test was used for groups comparisons (α = 0.05). Results: Individuals' mean age at baseline was 2.93 (± 1.18) years. No statistically significant differences were observed in the missing tooth space in the group with tooth loss during the 24 months of follow-up (p > 0.05). Arch perimeter, arch length, arch width, intercanine length and intercanine width did not show differences between the groups (p > 0.05). Qualitative photographic evaluation revealed other changes in the dental arches and occlusion, such as exfoliation and eruption of deciduous teeth, eruption of permanent teeth, self-correction or establishment of malocclusion, among others. Conclusion: The results suggest that the premature loss of deciduous anterior teeth does not affect the perimeter, length and width of the dental arches; however, other alterations that lead to malocclusion could be established.

RESUMO Objetivo: Este estudo teve como objetivo avaliar o desenvolvimento da oclusão após perda prematura ou extração de dentes decíduos anteriores, por meio de um estudo de coorte prospectivo. Métodos: Quinze bebês e crianças de 1 a 5 anos foram avaliados longitudinalmente (com perda ou extração de dentes anteriores decíduos [n = 9] e sem perdas dentárias [n = 6]). Foram realizadas fotografias e modelos dentais no início e após 24 meses de acompanhamento. Os modelos dentários foram escaneados e medidas lineares foram feitas nos modelos digitalizados (espaço dentário perdido, perímetro da arcada, comprimento da arcada, largura da arcada, comprimento intercaninos e largura intercaninos). O teste t foi utilizado para comparações entre grupos (α = 0,05). Resultados: A média de idade dos indivíduos no início do estudo foi de 2,93 (± 1,18) anos. Não foram observadas diferenças estatisticamente significativas no espaço dentário perdido no grupo com perda dentária durante os 24 meses de acompanhamento (p > 0,05). O perímetro da arcada, comprimento da arcada, largura da arcada, comprimento intercaninos e largura intercaninos não apresentaram diferenças entre os grupos (p> 0,05). A avaliação fotográfica qualitativa revelou alterações nas arcadas dentárias e na oclusão, como: esfoliação e erupção de dentes decíduos, erupção de dentes permanentes, autocorreção ou estabelecimento de má oclusão, entre outras. Conclusão: Os resultados sugerem que a perda prematura de dentes anteriores decíduos não afeta o perímetro, comprimento e largura das arcadas dentárias; entretanto, outras alterações que levam à má oclusão poderiam ser estabelecidas.
