Objectives The aim of this pilot case–control study was to investigate the association of clinical variables and genetic polymorphisms in the vitamin D receptor gene (VDR) with dental implant loss. Material and Methods This study was carried out with 244 individuals with mean age 51.90 ± 11.28 (81 cases and 163 controls matched by age, sex, and smoking habit). Also, the clusterization phenomenon was investigated stratifying the sample into two groups: (a) 34 patients with multiple losses (presenting two or more lost implants) and (b) 210 without multiple losses (up to one implant loss). Sociodemographic, clinical, and periodontal parameters were analyzed. The tagSNPs in the VDR gene were analyzed by real‐time PCR. Univariate and multivariate analyses were performed (p < .05). Results Edentulism, number of implants installed, and Gingival, Plaque, and Calculus Indexes were associated with implant loss in the univariate analysis. After the multivariate analysis, the allele G of rs3782905 in the recessive model, together with number of installed implants and Gingival Index, was associated with implant failure. Conclusion It is suggested that the allele G of rs3782905 in the recessive model may be a new genetic risk marker for dental implant loss in patients who lost two or more dental implants. In addition, number of implants installed and Gingival Index were also associated. Replication is mandatory to confirm these findings, due to the modest sample size of this work.
Objectives To evaluate postoperative pain after endodontic treatment of necrotic teeth using large intentional foraminal enlargement (LIFE). Materials and Methods The sample included 60 asymptomatic necrotic teeth (with or without chronic apical periodontitis), and a periodontal probing depth of 3 mm, previously accessed and referred to perform endodontic treatment. After previous procedures, the position and approximate size of the apical foramen (AF) were determined by using an apex locator and K flexo-files, respectively. The chemomechanical preparation was performed with Profile 04 files 2 mm beyond the AF to achieve the LIFE, using 2.5 mL of 2.5% NaOCl at each file change. The filling was performed by Tagger's hybrid technique and EndoFill sealer. Phone calls were made to all the patients at 24, 48 and 72 hours after treatment, to classify postoperative pain. Statistical analysis was performed by different tests with a significance level of 5%. Results Age, gender, periradicular status and tooth type did not influence postoperative pain ( p > 0.05). Only 1 patient (1.66%) reported severe pain after 72 hours. Moderate pain was reported by 7, 4 and 3 patients after 24, 48 and 72 hours, respectively ( p = 0.0001). However, paired analyses showed a statistically significant difference only between 24 and 72 hours ( p = 0.04). Sealer extrusion did not influence the postoperative pain ( p > 0.05). Conclusions Acute or moderate postoperative pain was uncommon after endodontic treatment of necrotic teeth with LIFE. Trial Registration The Brazilian Clinical Trials Registry Identifier: RBR-3r967t
Objective: To study the influence of black space between the maxillary central incisors on the aesthetic visual perception of the face, via eye-tracking and visual analogue scale (VAS). Methods: Black space between the central incisors was created, for both sexes, as follows: control, 1-mm black space, 2-mm black space and 3-mm black space. Ninety raters participated in this study, divided into three groups: 30 laypeople, 30 nonorthodontists, and 30 orthodontists. After the visual calibration of each observer, eight photographs were presented in the Ogama® software concomitant with the use of the hardware The Eye Tribe®. Ogama generated information depending on the eye-tracking of each rater, regarding the time until the first fixation, time of fixation, heatmap, scanpath, and total time of fixation, to evaluate the areas deemed to be of interest according to the raters. Later on, the VAS was used, where each rater evaluated the images in an album on a scale of zero to 10 points. Results: The eyes and mouth were the areas more often noticed by the raters according to the heatmaps, while no significant difference was observed in time until the first fixation between the three groups of raters (p> 0.05). However, regarding the time of fixation on the mouth, a significant difference was observed (p< 0.05) when comparing the three groups. Conclusion: Black space has a negative effect on the aesthetic perception of the face. The amount of attention on the mouth is correspondent to the size of the black space.
Resumo A organização dos sistemas de saúde em redes de atenção à saúde (RAS) se apresenta como uma estratégia para superar a fragmentação das ações e serviços de saúde materno-infantil e qualificar a gestão do cuidado. O objetivo deste estudo foi validar o Instrumento de Avaliação de Redes de Atenção Materno-infantil (IARAMI), adaptado a partir do Instrumento de Avaliação de Redes de Atenção à Saúde. O processo de validação compreendeu a validação de face e construto. A metodologia utilizada para a validação de face incluiu a adaptação conceitual e semântica do instrumento e a análise por um painel de especialistas, por meio da técnica e-Delphi de consenso modificada. Após sua validação de face, o IARAMI foi aplicado em uma amostra de gestores de 99 municípios do estado do Paraná. A validação de construto foi conduzida por análise de consistência interna por meio do coeficiente alfa de Cronbach e de análise fatorial. A técnica de análise fatorial foi aplicada para cada uma das dimensões do instrumento, permitindo a análise de comunalidades. Os resultados evidenciaram que o IARAMI apresentou confiabilidade e validade, demonstrando ser uma ferramenta que pode auxiliar gestores e trabalhadores da saúde no planejamento, na gestão e na avaliação do grau de integração da rede de atenção à saúde materno-infantil.
