Objective To evaluate studies assessing the prevalence of dental caries and developmental defects of enamel (DDE) in individuals with chronic kidney disease (CKD) in comparison with individuals without CKD. Materials and methods Electronic searches were performed in PubMed, Web of Science, Scopus, Medline via Ovid, and ProQuest databases from their inception date until February 2018. Two review authors independently selected the studies, extracted data, and assessed the methodological quality. Meta‐analysis was performed. Results Twenty‐seven studies were included in this study. For permanent teeth, 14 studies found that individuals without CKD had higher dental caries scores than those with CKD. However, only five studies presented results with a statistically significant difference between groups. Among the studies evaluating primary teeth, five showed that individuals without CKD had higher dental caries scores than those with CKD. Five studies showed that individuals with CKD had a significantly higher prevalence of DDE than individuals without CKD. The meta‐analyses showed that individuals without CKD had significantly higher scores of dental caries teeth and surfaces than individuals with CKD. For DDE, no statistical difference between groups was observed. Conclusions Individuals with CKD present lower dental caries scores and a higher prevalence of DDE in comparison with individuals without CKD.

Objective The aim of this systematic review and meta‐analysis was to evaluate the experience of dental caries in individuals pre‐ or postliver transplant. Materials and Methods Searches in PubMed, Scopus, Web of Science, Ovid, and Lilacs from databases’ inception date up to April 2020 were undertaken. Gray literature and manual searches were also conducted. Observational studies were eligible. The retrieved references were evaluated by two independent reviewers. Meta‐analysis and risk of bias assessment using the University of Adelaide tool were conducted. The strength of the evidence was assessed with GRADE. Results The search retrieved 1990 references. Twenty‐four cross‐sectional studies were included. One subgroup analysis demonstrated no significant difference in the number of teeth with dental caries between pre‐liver transplant and healthy individuals (mean difference = 1.65, confidence interval = −0.87 to 4.17). The prevalence of dental caries among pre‐liver transplant individuals was 73.82% and in the post‐transplant individuals was 72.83%. In the included studies, the main concern regarding risk of bias was the absence of control for confounding variables. The strength of the evidence was very low. Conclusions Dental caries may be a relevant issue in pre‐ and postliver transplant individuals. Oral health counseling should be included in the care of pre‐ and/or postliver transplant individuals.

Aim: To systematically review the literature for observational studies evaluating periodontal outcomes in pre- and post-liver transplant (LT) individuals compared to a control group. Methods: Specific strategies were designed to search five databases and the grey literature. Hand-searches were also performed. The following periodontal outcomes were analyzed in pre-LT, post-LT and control groups: plaque index (PI), gingival index (GI), gingival growth (GO), alveolar bone loss (ABL) probing depth (PD) and clinical attachment level (CAL). Meta-analyses and subgroup analyses were conducted. Results: Among the 257 studies retrieved, 11 studies were included. Four studies were incorporated into the meta-analysis and showed that PI (mean difference=0.15, 95%CI: 0.12-0.18) and GI (mean difference=0.31, 95%CI: 0.06-0.56) were significantly higher in post-LT individuals compared to the control group. There was no significant mean difference of PD (mean difference=0.49, 95%CI: -0.26-1.25) but CAL (mean differ- ence=1.47, 95%CI: 0.19-2.75) were significantly higher in pre-LT individuals compared to the control group. Conclusion: The higher means of PI and GI in post-LT and CAL in pre-LT compared to healthy individuals suggest a relationship between the periodontal condition and the transplantation status.

Este estudo objetivou investigar a ansiedade em pacientes atendidos em clínicas odontológicas universitárias. O presente estudo transversal incluiu 49 pacientes recrutados nas clínicas odontológicas da Universidade Federal de Juiz de Fora, campus Governador Valadares, Minas Gerais, Brasil, de setembro de 2016 a agosto de 2017. Informações sobre sexo, idade, renda familiar, escolaridade, frequência de consultas odontológicas e procedimentos odontológicos causadores de desconforto foram coletadas por meio de questionário. O nível de ansiedade foi avaliado pela Dental Anxiety Scale. Observou-se um nível de ansiedade leve  (mediana = 6), com mínimo de 4 (não ansioso) e máximo de 19 (extremamente ansioso). As mulheres apresentaram maior ansiedade que os homens (p = 0,047). Indivíduos com 9 a 11 anos de escolaridade apresentaram menor nível de ansiedade odontológica do que aqueles com 0 a 8 anos de estudo (p = 0,025). Os participantes que atribuíram maior desconforto às cirurgias e ao uso de alta rotação apresentaram maior ansiedade (p = 0,002).  Conclui-se que a ansiedade leve está presente em pacientes submetidos a tratamento odontológico em clínicas universitárias, sendo as mulheres mais ansiosas do que os homens. Pacientes com maior grau de instrução foram menos ansiosos. O relato de maior desconforto com cirurgias e procedimentos alta rotação pode estar associado a uma maior ansiedade.
