RESUMO

OBJECTIVE: To monitor the cytokine release patterns in the peri-implant crevicular fluid (PICF) and to investigate which factors affect the success rate of narrow diameter implants (NDI) during the first year. MATERIAL AND METHODS: Mandibular implant overdentures (IOD) retained by 2 NDI were installed in 16 clinically atrophic edentulous patients. The following parameters were monitored during the first year: (i) peri-implant health parameters (plaque index (PI), calculus presence (CP), gingival index (GI), probing depth (PD) and bleeding on probing (BoP); (ii) cytokine concentrations in the PICF (TNF-α, IL-1ß, IL-6, IL-10); (iii) implant stability quotient (ISQ); (iv) marginal bone level (MBL) and bone level change (BLC); (v) implant success. The insertion torque, bone type, mandibular atrophy, time since edentulism, and smoking habits were also recorded. All data were analyzed using multivariable multilevel mixed-effects regression models. RESULTS: The variability in the TNF-α release patterns temporarily reduced at weeks (w) 8-12, while the IL-1ß concentrations remained low until they peaked at w48 [p < 0.05; + 177.55 pg/µl (+ 96.13 - + 258.97)]. Conversely, IL-10 release decreased significantly at w48 [p < 0.05; - 456.24 pg/µl (- 644.41 - - 268.07)]. The PD and ISQ decreased significantly (p < 0.05) over the follow-up period, while the MBL was stable after w48 with a BLC of 0.12 ± 0.71 mm. The overall success rate was 81.3%, and was influenced by TNF-α, IL-1ß, IL-10, PI, GI, PD, smoking, and time since edentulism. CONCLUSION: Pro- and anti-inflammatory cytokine release was balanced during the first 24 weeks. The GI, smoking, and time since edentulism are the most important factors determining the implant success. CLINICAL RELEVANCE: The study contributes to the understanding of the osseointegration process in a clinically atrophic population rehabilitated with IOD, and highlights the importance of monitoring clinical peri-implant health-related parameters, smoking habit, and time since edentulism to predict implant success rates.

RESUMO

STATEMENT OF PROBLEM: Although implant-retained mandibular overdentures (IMOs) provide functional benefits, the influence of the vertical facial pattern (FP) and the anteroposterior skeletal discrepancy (ASD) on the masticatory function and patient-centered outcomes during the transition to IMOs is still uncertain. PURPOSE: The purpose of this interventional clinical study was to evaluate the influence of the FP and ASD on the masticatory function, oral health-related quality of life (OHRQoL), and satisfaction of completely edentulous patients before and after transition to IMOs. MATERIAL AND METHODS: Cephalometric analysis was performed on 42 participants before treatment. Ricketts analysis was used to classify the FP, and the maxillomandibular relationship to the base of the skull determined the ASD. Masticatory performance (MP) and swallowing threshold (ST) test results were evaluated by the multiple sieve method by using artificial test food (Optocal cubes) to determine the median particle size (×50), homogenization index (B), and masticatory efficiency based on sieves 5.6 (ME: 5.6) and 2.8 (ME: 2.8). OHRQoL and satisfaction were evaluated by using the Dental Impact on Daily Living questionnaire. The data were analyzed using mixed-effects linear regression models to estimate the effect of time, FP, ASD, age, and sex on MP, ST, and OHRQoL. RESULTS: The MP, ST, OHRQoL, and satisfaction improved significantly after IMO loading, irrespective of FP and ASD. However, MP outcomes were most negatively affected mainly among dolichofacial (B and ME: 2.8), class II, and class III (×50, B, and ME: 2.8) participants. The ST test showed that class II participants still showed inferior ×50 values and performed a lower number of cycles than class I and class III participants. Women presented reduced masticatory function for all MP and ST outcomes and reported lower coefficients for appearance and general performance domains than men. CONCLUSIONS: The MP test detected more subtle improvements than the ST test, especially in class III participants. The class II participants benefited the least from the IMO installation according to the ST test. The IMO treatment improved the OHRQoL and satisfaction of edentulous patients, irrespective of the FP or ASD.

RESUMO

The aim of this paper is to systematically review the literature to estimate the overall prevalence of xerostomia/hyposalivation in epidemiological studies. An electronic search was carried out up to February 2018 with no language restrictions. A total of 5760 titles were screened and just twenty-nine papers were included in review and the meta-analysis after a two independently reviewers applied the selection criteria. Data were extracted from PubMed and Web of Science databases. Eligibility criteria included original investigations from observational population-based studies that reported the prevalence of xerostomia or data that allowed the calculation of prevalence of xerostomia and/or hyposalivation. Studies conducted in samples with specific health conditions, literature reviews, case reports and anthropological studies, as conferences or comments were excluded. Sample size, geographic location of the study, study design, age of the studied population, diagnosis methods, and evaluation criteria used to determine xerostomia e/or hyposalivation were extracted for meta-analysis and meta-regression. Multivariate meta-regression analysis was performed to explore heterogeneity among studies. The overall estimated prevalence of dry mouth was 22.0% (95%CI 17.0-26.0%). Higher prevalence of xerostomia was observed in studies conducted only with elderly people. Despite diverse approaches to the condition's measurement, just over one in four people suffer from xerostomia, with higher rates observed among older people. Moreover, the measurement methods used currently may over- or underestimate xerostomia. These findings highlight the need for further work on existing and new clinical measure and will be useful to determine which one is more reliable in clinical and epidemiological perspectives.

Resumo O objetivo do estudo é revisar sistematicamente a literatura afim de estimar a prevalência global de xerostomia/hiposalivação em estudos epidemiológicos. Uma busca eletrônica foi conduzida até Fevereiro de 2018 sem restrições de linguagem. Um total de 5760 títulos foram inicialmente identificados e somente vinte e nove artigos foram incluídos na revisão e meta-análise após dois revisores independentes aplicarem os critérios de seleção. Os artigos foram extraídos das bases de dados PubMed/Medline e Web of Science. Os critérios de elegibilidade incluíram investigações originais de estudos observacionais de base populacional os quais reportaram a prevalência de xerostomia ou dados que permitissem o cálculo da prevalência de xerostomia e/ou hiposalivação. Estudos realizados em populações com condições de saúde específicas, revisões de literatura, relato de casos e estudos antropológicos, assim como, conferências ou comentários foram excluídos. Tamanho amostral, localização geográfica aonde foi realizado o estudo, desenho do estudo, idade da população estudada, métodos de diagnóstico e o critério de avaliação para determiner xerostomia e/ou hiposalivação foram extraídos para a meta-análise e metaregressão. Análise de meta-regressão multípla foi realizada para explorar a heterogeneidade entre os estudos. A prevalência global estimada de boca seca foi de 22.0% (95%IC 17.0-26.0%). Uma maior prevalência de xerostomia foi observada em estudos realizados exclusivamente em populações idosas. Apesar de diferentes abordagens utilizadas para mensurar as condições de interesse, cerca de uma em quatro pessoas é acometida por xerostomia, com taxas mais elevadas sendo observadas na população idosa. Além disso, os métodos de mensuração podem ter super- ou subestimado os valores de xerostomia. Os achados do presente estudo salientam a necessidade de mais estudos acerca das existentes e novas formas de avaliação clínica, os quais serão úteis para determinar qual é a mais confiável para as perspectivas clínicas e epidemiológicas.

RESUMO

Several instruments have been used to measure oral health-related quality of life (OHRQoL). The Oral Health Impact Profile (OHIP) questionnaire was based on the concept that sequential events related to oral diseases can cause discomfort, functional limitations and consequently, result in dysfunctions and even disabilities. There are few studies in the literature that structurally analyze the instruments to verify whether they measure the requirements to which they were designed to. The objective of the study was to evaluate the internal structure of the OHIP-Edent questionnaire. The OHIP-Edent was administered to 54 edentulous patients' wearers of conventional complete dentures. For structural analysis, an exploratory factorial analysis (EFA) was carried out. After determining the internal consistency of the model (Cronbach's alpha = 0.88), the fit was checked using the root mean square error approach (value 0.04), the comparative fit index (value 0.982) and the Tucker-Lewis index (value 0.976). After analysis of the 19 questions and the seven domains proposed in the OHIP-Edent questionnaire, the hypothetical factorial model showed three dimensions denominated "Physical Impact", "Psychological Impact" and "Social Impact". In this sample of conventional complete denture wearers, the OHIP-Edent seems adequate to measure the "Physical Impact", "Psychological Impact", and "Social Impact" of the OHRQoL. The confirmatory factorial analysis confirmed the model and, through adjustment indexes, it was verified that the three dimensions have convergence and consistence adequate in order to characterize the OHRQoL construct with validity.

RESUMO

Aim: The etiology and epidemiology of maxillofacial injuries varies widely in different regions of the world due to socioeconomic status, cultural aspects in addition to road traffic and drug consumption. The aim of this study is to determine major causes and epidemiological characteristics of maxillofacial trauma in a 5-year period. Materials and methods: Reports of corporal trauma (n = 25,632) from 2007 to 2011 in the Department of Forensic Medicine were analyzed as to the presence of maxillofacial injuries. Data were submitted to Chi square test and to multivariate Poisson regression. Results: 3262 reports referred maxillofacial trauma. The majority were men (55.8%), single (68.9%), most of them white (75.7%). The average age was 28.9 years (SD = 8.42), and victims with age between 16 and 30 years old were the most affected (48.0%). Women comprised 44% of total sample, 67.8% (971) were single, 76% (1.076) white and 46% (691) aged between 16 and 30 years old. Middle third injuries were associated after adjustment with females (PR 1.05; 95% CI 1.01-1.11), non-white subjects (PR 1.06; 95% CI 1.01-1.12) and physical aggression (PR 1.07; 95% CI 1.02-1.13). Injuries in the oral region was more prevalent in men (PR 1.24; 95% CI 1.09-1.41), in those aged between 16 and 30 (PR 1.97; 95% CI 1.48-2.61) and in subjects with injuries caused by traffic accident (PR 1.21; 95% CI 1.02-1.44). The presence of injuries in the lower third of face remained associated in the final model only with traffic accident (PR 1.75; 95% CI 1.43-2.15). Conclusion: Health care practitioners must recognize vulnerable population and most prevalent sites of lesion to identify cases of violence.

RESUMO

Objective: To evaluate a possible association between tooth erosion and weight status in Brazilian schoolchildren. Material and Methods: 1211 children aged 8-12-year-old from public and private schools in Southern Brazil were selected by a two-stage cluster method. Oral conditions were assessed by six trained and calibrated examiners. Tooth erosion assessment was determined by using the O´Sullivan index. Anthropometric measures were taken in order to obtain the body mass index. Socio-demographic and behavioral data were collected using questionnaires in children and parents. Multivariate Poisson regression model considering the cluster sample was used for data analysis (Prevalence ratio - PR; 95% Confidence Interval - CI). Results: Tooth erosion was observed in 25.1% of the children. Obesity and overweight prevalence was 34.6%. In the multivariate adjusted model, tooth erosion was associated with children from private schools (PR 1.68; 95%CI 1.05-2.68) and higher frequency of physical activity weekly (PR 1.48; 95%CI 1.04-2.09), whereas dental crowding in both arches was considered a protective effect (PR 0.55; 95%CI 0.34-0.89). In the stratified analysis regarding the type of school, children from private schools presented a positive association between tooth erosion and obesity (PR 3.26; 95%CI 1.38-7.69). Conclusion: Tooth erosion was not associated with obesity in the total sample. Socioeconomic differences seem to influence the relationship tooth erosion and obesity.

RESUMO

OBJECTIVES: The aim of this prospective clinical study was to evaluate the masticatory function (MF) and subjective perception of patients with poor denture-bearing tissue in relation to change and the time required to identify an improvement in these parameters after rehabilitation with mandibular overdentures (MO) by two narrow-diameter two-piece implants. MATERIAL AND METHODS: Twenty-three edentulous patients were selected for MO installation. The masticatory function (MF) was evaluated with the masticatory performance (MP) and swallowing threshold (ST) tests. In the MP test, each volunteer was instructed to masticate a portion of Optocal (standardized artificial test food) for 40 masticatory cycles. During the swallowing threshold test, the patients were instructed to chew a new portion of Optocal cubes until they felt the desire to swallow. The MF tests were performed while complete denture (CD) wearers (baseline) and 1, 3, 6, and 12 months after MO loading. In addition, the subjective perception was assessed through the questionnaires Dental Impact on Daily Living (DIDL), Geriatric Oral Health Assessment Index (GOHAI), and Oral Health Impact Profile in Edentulous (OHIP- EDENT) at the baseline and 3, 6, and 12 months after MO loading. RESULTS: A significant improvement in masticatory function (p < .05) was observed already in the first month of loading. Three months after MO loading, a significant improvement (p < .05) was found in the subjective perception of patients. The effect size indicates that the MO had the greatest impact on the domains related to function and comfort of all questionnaires and in relation to psychosocial domain of the GOHAI. The level of patient satisfaction increased significantly after the MO loading and reached >90% satisfied patients at 12 months. CONCLUSION: The MO improved both the MF of the patient and their oral health-related quality of life and satisfaction regarding the prosthesis in a short time period.

RESUMO

OBJECTIVE: To investigate the microbial diversity existing in oral cavity and respiratory tract samples (from mini-bronchoalveolar lavage (BAL), endotracheal aspirate, and orotracheal tube) of patients on mechanical ventilation by using the checkerboard DNA-DNA hybridisation. Also, the study aimed to evaluate whether the microbial profile in the oral cavity is found in respiratory tract samples, at different periods of mechanical ventilation time (12h, 48h, 96h) in attempt to identification of relationship between VAP (ventilator-associated pneumonia) and bacterial species studied. The last objective was to analyses correlation between blood cultures and VAP. DESIGN: The samples were collected from ten patients in intensive care unit with medical prescription of orotracheal intubation and mechanical ventilation. Clinical data were tabulated and blood cultures were performed according medical indication. For checkerboard samples collection, chosen sites were the dorsal side of the tongue and gingival sulcus at 12h, 48h, 96h, BAL, at 12h, endotracheal aspirate at 48 and 96h, and orotracheal tube at extubation time, when feasible. RESULTS: It was possible to identify the presence of bacterial species in mouth and in the BAL/endotracheal aspirate. The data demonstrated an increase in the quantity of bacterial associated with prolonged use of mechanical ventilation (48 and 96h). CONCLUSIONS: Bacterial species may migrate rapidly from mouth and upper airways during orotracheal intubation which contributes to the pathogenesis of VAP. There were associations between VAP and Enterococcus faecalis, Fusobacterium periodonticum, Gemella morbillorum, Neisseria mucosa, Propionibacterium acnes, Prevotella melaninogenica, Streptococcus oralis, Streptococcus sanguinis, Treponema denticola, Treponema socransckii, and Veillonella parvula.

RESUMO

The objective of this study was to realize a scoping review the literature in order to identify the profile of DPSCs isolation and analyze the possible risk factors that could change the native behavior of these cells. An initial search was conducted using the following MeSH terms: "(dental pulp stem cell [MeSH])"; "(dental pulp [MeSH])" AND "(stem cell [MeSH])"; "("dental pulp stem cell" [MeSH]")". The electronic search was done without date restriction up to and including April 2014, in PubMed, Scopus, Scielo and ISI Web of Knowledge databases. Studies were submitted to inclusion and exclusion criteria and 222 articles were included. Data showed that over the past 15 years many studies have been conducted using DPSCs. However this is the first systematic review regarding the isolation of stem cell, and more specifically of dental pulp stem cells. The isolation of dental pulp stem cells showed great variability, hampering the development of standard protocols to achieve in vitro dental pulp stem cells with similar characteristics. This scoping review combined, for the first time, the methodologies used for dental pulp stem isolation, highlighting the most frequently used.

RESUMO

This systematic review and meta-analysis aimed to evaluate the relationship between endotoxin levels and presence of clinical signs/symptoms and radiographic features in patients with endodontic infection. Electronic searches were performed on Medline/PubMed, Embase, Cochrane Library, Scielo, Science Direct, Web of Knowledge and Scopus databases for identification of relevant studies published up to December 2016. Grey literature was searched in Google Scholar. The selected literature was reviewed independently by two authors. Clinical studies evaluating the levels of endotoxin and the presence of clinical and radiographic features were included in this review. In order to determine the relationship between endotoxin levels and presence of clinical signs/symptoms and radiographic features meta-analyses were performed. Among the 385 articles identified in the initial search, 30 were included for full-text appraisal and only eight studies met the inclusion criteria for this systematic review. Meta-analysis revealed that individuals having teeth with tenderness to percussion (TTP) (P = 0.04; I2 57%) and previous episode of pain (PEP) (P = 0.001; I2 81%) had higher levels of endotoxin than their counterparts. Size of radiographic lesion >2 mm (P = 0.02; I2 68%) and presence of root canal exudation (EX) (P = 0.0007; I2 0%) were associated with higher levels of endotoxin. This systematic review and meta-analyses provided a strong evidence that endotoxin are related with the presence of clinical signs/symptoms and radiographic features in patients with endodontic infection.

RESUMO

The aim of this longitudinal observational study was to evaluate the oral health-related quality of life (OHRQoL) following patient rehabilitation with implant-retained mandibular overdentures (IMO) and to identify the contribution of the different domains to OHRQoL. The Oral Health Impact Profile (OHIP-EDENT), Dental Impact on Daily Living (DIDL), and Geriatric Oral Health Assessment Index (GOHAI) questionnaires were completed twice by 25 patients: after 3 months of rehabilitation with complete dentures (CD) and after 3 months of IMO loading using stud abutments. The evaluation after IMO rehabilitation showed significant improvement in three DIDL domains: appearance (p = 0.011), eating and chewing (p = 0.003), and general performance (p = 0.003). The GOHAI results showed significant differences in two domains: psychosocial (p = 0.005) and pain and discomfort (p = 0.0004). The OHIP-EDENT outcomes showed significant improvements in five domains: functional limitation (p = 0.0001), physical pain (p = 0.0002), physical disability (p = 0.0010), and psychological disability and handicap (p = 0.032). The largest observed effect sizes were close to one standard deviation and were observed in the eating and chewing domain (0.93) of the DIDL; the pain and discomfort domain (0.83) of the GOHAI, and the functional limitation (0.89), physical pain (1.02), physical disability (0.84) domains of the OHIP-EDENT. The percentage of satisfied patients increased in all domains. Self-reported OHRQoL of CD wearers was significantly improved after 3 months of treatment with IMO, especially concerning the functional and pain-related aspects.

RESUMO

PURPOSE: This cross-sectional study analyzes how bone resorption affects the masticatory function and investigates the relation between perceived and measured masticatory function. METHODS: Thirty complete dentures wearers were divided in two groups according to mandible bone atrophy based on the classification criteria from Cawood & Howell. Retention and stability of the mandibular complete denture, masticatory performance (MP) indexes (X_50 and B) and masticatory efficiency (ME, sieves 4 and 2.8) were evaluated. Geriatric Oral Health Assessment Index (GOHAI) and Dental Impact on Daily Living (DIDL) questionnaires were completed by the patients. RESULTS: A strong correlation between bone atrophy and poor retention was found (P=0.0132). Neither masticatory performance indexes nor GOHAI and DIDL domains showed statistical differences (P>0.05) when patients were compared according to the atrophy criteria. Mandibular length showed a negative correlation with ME4, showing a positive association (R2=0.17, ß=-0.67, P=0.029). Mandibular denture retention was significantly correlated with MPB (P=0.01) and ME2.8 (P=0.01). GOHAI showed a positive association between the physical and the functional domains and ME2.8 (R2=0.17; ß=1.22; P=0.02). DIDL showed a negative association between ME4 and oral comfort domain (R2=0.16; ß=-2.94; P=0.02). CONCLUSION: Mandibular bone height does not directly affect the masticatory function and is inversely correlated with the self-perceived masticatory ability.

The Oral Health Impact Profile (OHIP-EDENT), Dental Impact on Daily Living (DIDL), and Geriatric Oral Health Assessment Index (GOHAI) questionnaires were completed twice by 25 patients: after 3 months of rehabilitation with complete dentures (CD) and after 3 months of IMO loading using stud abutments. The evaluation after IMO rehabilitation showed significant improvement in three DIDL domains: appearance (p = 0.011), eating and chewing (p = 0.003), and general performance (p = 0.003). The GOHAI results showed significant differences in two domains: psychosocial (p = 0.005) and pain and discomfort (p = 0.0004). The OHIP-EDENT outcomes showed significant improvements in five domains: functional limitation (p = 0.0001), physical pain (p = 0.0002), physical disability (p = 0.0010), and psychological disability and handicap (p = 0.032). The largest observed effect sizes were close to one standard deviation and were observed in the eating and chewing domain (0.93) of the DIDL; the pain and discomfort domain (0.83) of the GOHAI, and the functional limitation (0.89), physical pain (1.02), physical disability (0.84) domains of the OHIP-EDENT. The percentage of satisfied patients increased in all domains. Self-reported OHRQoL of CD wearers was significantly improved after 3 months of treatment with IMO, especially concerning the functional and pain-related aspects.

RESUMO

Abstract: The objective of this study was to realize a scoping review the literature in order to identify the profile of DPSCs isolation and analyze the possible risk factors that could change the native behavior of these cells. An initial search was conducted using the following MeSH terms: "(dental pulp stem cell [MeSH])"; "(dental pulp [MeSH])" AND "(stem cell [MeSH])"; "("dental pulp stem cell" [MeSH]")". The electronic search was done without date restriction up to and including April 2014, in PubMed, Scopus, Scielo and ISI Web of Knowledge databases. Studies were submitted to inclusion and exclusion criteria and 222 articles were included. Data showed that over the past 15 years many studies have been conducted using DPSCs. However this is the first systematic review regarding the isolation of stem cell, and more specifically of dental pulp stem cells. The isolation of dental pulp stem cells showed great variability, hampering the development of standard protocols to achieve in vitro dental pulp stem cells with similar characteristics. This scoping review combined, for the first time, the methodologies used for dental pulp stem isolation, highlighting the most frequently used.

RESUMO

This study aimed to describe the profile of motorcycle users and determine the prevalence of use. Also, to evaluate the reason for using a motorcycle, users' perceived risk of traffic accident, pattern of helmet wearing and number of accidents related to motorcycle use in the last 12 months. This cross-sectional study was conducted in the city of Pelotas, Southern Brazil. Sampling process was carried out in two stages, with the primary unit being the census track and the secondary the house. The study included 3,004 individuals aged 10 to 59 years, which answered a structured questionnaire. The outcome of the study was the use of motorcycle. The prevalence of motorcycle use was 25%. The majority of the riders were composed by males (79%). Individuals aged from 18 to 35-years-old comprised 42% of the total number of users, mainly as riders (24%). Forty percent of the users were not using properly the helmet strap. The major part of the users (76%) had a perception of high risk for accidents. The prevalence of accidents was 8%; it was higher among males and among those individuals aged from 18 to 35 years. The use of motorcycle was widespread in the population. Users were aware of the risk of accident, even though they reported to not wear correctly the helmet.

RESUMO

Abstract The aim of this study was to estimate self-reported prevalence of edentulism, severe tooth loss and lack of functional dentition in elders, and to identify potential associated factors. A population based cross-sectional study was carried out with 1,451 elders (≥60 years), in Pelotas, RS, Brazil. Crude and adjusted prevalence ratios were estimated using Poisson regressions. The prevalence of edentulism, severe tooth loss and lack of functional dentition was 39.3%, 60.9% and 82.7%, respectively. The factors positively associated with tooth loss in the three-degree severity were sex (females), older individuals, low familial income, low level of schooling and having the last dental visit longer than 24 months ago. The high prevalence of tooth loss in its different degrees of severity and the association with preventable factors highlight the need of programs focused on elders, emphasizing the prevention of tooth loss and need for prosthetic rehabilitation.


Resumo O objetivo deste estudo foi estimar as prevalências autorreferidas de edentulismo, perda dentária severa e ausência de dentição funcional em idosos, assim como identificar potenciais fatores associados. Um estudo transversal de base populacional foi realizado com 1.451 idosos (≥60 anos), em Pelotas, RS, Brasil. Razões de prevalência brutas e ajustadas foram estimadas por meio de regressões de Poisson. As prevalências verificadas foram 39,3% para edentulismo, 60,9% para perda dentária severa e 82,7% para ausência de dentição funcional. Os fatores associados positivamente à perda dentária nos seus três diferentes graus de severidade foram sexo feminino, idade avançada, baixa renda familiar, baixa escolaridade e última consulta odontológica há mais de 24 meses. As altas prevalências de perda dentária nos seus diferentes graus de severidade e a constatação de fatores associados passíveis de intervenção alertam para necessidade de medidas e programas que priorizem a faixa etária idosa com ênfase na prevenção da perda dentária e na reabilitação protética.
