RESUMO

Introduction. Streptococcus mutans is an important cariogenic microbe.Hypothesis/Gap Statement. The potential characteristics of S. mutans isolates from site-specific dental plaque are still not clear.Aim. This study aimed to investigate the phenotypic and genetic characteristics of S. mutans isolates from site-specific dental plaque in China.Methodology. We used S. mutans isolated from children with early-childhood caries (ECC) and caries-free children to compare the phenotypic and genetic characteristics of S. mutans from site-specific dental plaque samples. The ECC subjects presented two sites: a cavitated lesion and a sound surface. The caries-free subjects presented one sound surface. Growth pattern, biofilm, decrease in pH, extracellular polysaccharide, expression levels of virulence-related genes, multilocus sequence typing (MLST) and phylogenetic trees were evaluated among these three sites.Results. The phenotypes detected between the cavitated and sound surfaces of ECC children were similar. However, the capacity for biofilm formation, pH drop and expression levels of genes (gtfB and spaP) of S. mutans in the caries-free group were lower compared with those of the ECC group. We identified 44 new alleles and 77 new sequence types. More than 90 % of the children with ECC shared an identical sequence type. The distribution of sequence types among different subjects showed diversity, and child-to-child transmission was detected.Conclusions. This is the first report of MLST on site-specific dental plaques in a single subject, and indicates that S. mutans isolated from site-specific dental plaque of a single subject showed similar phenotypes as a result of the isolates were closely related.

RESUMO

BACKGROUND: Dental caries is considered as one of the most significant global health problem over the world. Dental caries initiates from bacterial shifts within the supragingival biofilm, then a polymicrobial biofilm is formed on the surface of tooth, and finally various bacterial species aggregate in a complex-organized manner. The exploiting variability in 16S rRNA gene sequence has been considered as a cost-efficient high-throughput characterization approach in human oral microbiome investigations. The aim of this study is to characterize bacterial species associated with superficial dental biofilm, underlying carious dentine and root caries lesion by16S rRNA gene-based metagenomic analysis. MATERIAL AND METHODS: Herein, the bacterial communities in carious dentin lesion, biofilm and root canal samples of 30 subjects (aged 4-76 years) admitted to a clinic in Tehran during 2017 were investigated using a culture independent approach. Total genomic DNA of each tissue was subjected to metagenomic identification of bacteria using a nested PCR assay and 16S rRNA library construction method. RESULTS: 31 samples collected from 30 consenting patients (29 samples from 29 patients ant two biofilm samples from one patient). Bioinformatics analyses of a-800bp sequences of the second step of Nested-PCR revealed presence of 156 bacterial isolates in carious (n = 45), biofilm (n = 81) and root canal (n = 30) specimens. Prevotella spp., Lactobacillus vaginalis, and streptococcus spp. showed higher prevalence in carious dentin, root and biofilm samples, respectively. CONCLUSIONS: Exploring the dental microbiota and comparing them in health or diseased conditions is critical step in the determination of human general health. The method applied in this study could identify bacteria related to the three dental lesions. However, due to lack of data for comparison in Genbank or because of the sequence similarity lower than 98% for most identified bacteria, the use of more powerful approaches like NGS platforms or typing of multiple loci (MLST) in future studies is recommended

RESUMO

BACKGROUND: To date, a few studies have documented the detailed periodontal conditions of a Japanese population. It is important to know if the awareness of Japanese nationals and dentists regarding oral hygiene and prevention of periodontal disease have improved when compared with the past in Japan for the development of future scenarios regarding prevention. The aim of this study was to investigate the severity, prevalence, and extent of periodontal disease in the adult population of the city of Takahagi, Japan. Results were also compared with those of an epidemiological study performed in Japan in the 1980s. METHODS: A total of 582 (aged 20 to 89 years) randomly sampled Takahagi residents answered a comprehensive questionnaire and participated in clinical examinations. RESULTS: The mean percentages of tooth surfaces harboring plaque and exhibiting BOP were 59.5 ± 20.9% and 31.1 ± 21.1%, respectively. The mean PPD and CAL were 2.5 ± 0.5 mm and 2.9 ± 1.0 mm, respectively. Compared with results of the 1980s survey, the mean percentages of plaque and bleeding on probing were lower in the current population. The mean CAL and prevalence of attachment loss of ≥5 mm in some age groups were higher in the present study than in the 1980s study. There were no statistically significant differences with respect to mean probing depth between the 1980s and current age groups. CONCLUSIONS: Periodontal disease was still prevalent in the current Japanese population, even though some improvement occurred. Proper public health programs therefore need to be established.

RESUMO

Objective: The aim of this study was to compare the periodontal status and dental behaviour of heart transplant recipients with systemically healthy controls.Material and Methods: Forty heart transplant recipients and 40 systemically healthy patients were included. A questionnaire was used to record demographic, systemic health and dental behaviour data, and the following clinical parameters were recorded: plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level.Results: Mean probing depth (p = .045), mean gingival recession (p = .016), mean clinical attachment level (p = .021) and mean plaque index scores (p = .001) were higher in heart transplant recipients than the systemically healthy group. However, bleeding on probing was similar in both groups (p > .05). Tooth brushing frequency and number of participants who used dental floss/interdental brush was lower in the heart transplant group.Conclusion: Considering the poor oral hygiene and high clinical periodontal parameters of heart transplant recipients, periodontal evaluation should be done regularly before and after transplantation. The patient's daily oral hygiene regimens should be evaluated carefully in this evaluation session and modified based on their gingival health, manual skill and motivational levels. The importance of oral health and its effects on systemic health should also be explained to the transplant recipients in detail.

RESUMO

BACKGROUND: Dental caries and overweight/obesity are health problems with shared risk factors, but the relationships between caries and BMI need to be further explored. The objective was to evaluate the current status of dental caries and the association between dental caries and Body Mass Index (BMI) among primary and secondary school students in Shenzhen, China, during the 2016-2017 academic year. METHODS: A population-based, cross-sectional study that enrolled a total of 1,196,004 students was conducted in Shenzhen. Physical and dental examinations were given to all primary and secondary school students by certified physicians and dentists following the national specification for student health examinations, and dental caries was diagnosed using WHO criteria. Descriptive analysis was applied to assess current oral health status and a multifactorial, logistic regression model was employed to evaluate the relationship between dental caries and obesity. RESULTS: A total of 1,196,004 students participated in the census. Mean age of the participants was 10.3 years, ranging from 6 to 20 years. The prevalence of dental caries was 41.15% in the present study, which was higher among girls (42.88%) than that in boys (39.77%) with a p-value of < 0.001. Students in public schools showed a significantly lower (p < 0.001) caries prevalence (37.36%) compared with those in private schools (47.96%). The caries restoration rate of students in Shenzhen was only 10.30%, which means only one out of ten students with caries received restorations. The mean dmft and DMFT scores were 0.97 and 0.33, respectively. More girls (10.96%) had their teeth filled than boys (9.78%). The restoration rate was higher (p < 0.001) in public schools (11.73%) than in private ones (8.35%). Children who were overweight or obese had a lower risk of experiencing caries compared to those who were within a normal weight (OR = 0.74/0.64). Caries was inversely associated with BMI among primary and secondary school students in Shenzhen. CONCLUSIONS: The prevalence of dental caries among primary and secondary school children was found to be related to sex, type of schools, region, and BMI. Further studies and more government support are required to confirm the findings of this study and to address current oral health problems.

RESUMO

RESUMEN Introducción: Durante la gestación, algunos cambios fisiológicos en la mujer propician un incremento de la placa dental y de la microbiota cariogénica. Esta condición unida a una modificación de la dieta y a una inadecuada higiene bucal condicionarían desfavorablemente la salud oral tanto de la madre como del bebé. Objetivo: Determinar el efecto antibacteriano de una pasta dental con xilitol sobre el recuento de Streptococcus mutans en saliva de gestantes. Métodos: Ensayo clínico, a doble ciego, que se realizó en el Centro de Salud "José Olaya" (Chiclayo Perú), en enero de 2017. Se trabajó con una población muestral de 50 gestantes en el segundo trimestre que cumplieron con los criterios establecidos. Se crearon dos grupos: 25 gestantes usaron dentífrico con 10 por ciento de xilitol y 25 gestantes usaron dentífrico sin xilitol. Se les tomó y proceso microbiológicamente una muestra de saliva antes del inicio del estudio y 14 días después del uso de las respectivas pastas. Se realizó el recuento de unidades formadoras de colonias de Streptococcus mutans en saliva con una confiabilidad altamente significativa mediante el coeficiente de correlación intraclase, calibración intra e interexaminador (1,000 y 0,999, respectivamente). El análisis de los datos se realizó mediante la prueba U de Mann-Whitney, considerando un nivel de significancia del 5 por ciento. Resultados: No se encontró diferencia significativa entre las gestantes que emplearon pasta dental con xilitol en comparación con las que utilizaron pasta dental sin xilitol (p= 0,062). Conclusiones: El efecto antibacteriano de la pasta dental comercial con xilitol es similar a una pasta dental sin xilitol sobre el recuento de Streptococcus mutans en saliva de gestantes(AU)


ABSTRACT Introduction: Some physiological changes occur in women during pregnancy which cause an increase in dental plaque and cariogenic microbiota. This situation, alongside a modification in the diet and inadequate oral hygiene, negatively affect the oral health of both the mother and the baby. Objective: Determine the antibacterial effect of a toothpaste with xylitol on the count of Streptococcus mutans in pregnant women's saliva. Methods: A double-blind clinical trial was conducted in José Olaya Health Center (Chiclayo, Peru) in January 2017. The sample population was 50 women in the second trimester of pregnancy who met the established inclusion criteria. Two groups were formed: 25 pregnant women used a toothpaste with 10 percent xylitol and the other 25 used a toothpaste without xylitol. A saliva sample was taken and processed microbiologically before the start of the study and 14 days after use of the two toothpastes. A count was performed of colony-forming units for Streptococcus mutans in saliva with highly significant reliability, using the intraclass correlation coefficient, and intra- and inter-rater calibration (1.000 and 0.999, respectively). Data analysis was based on the Mann-Whitney U Test, with a significance level of 5 percent. Results: No significant difference was found between the pregnant women who used the toothpaste with xylitol and those who used the toothpaste without xylitol (p= 0.062). Conclusions: The antibacterial effect of the commercial toothpaste with xylitol is similar to that of a toothpaste without xylitol in terms of the Streptococcus mutans count in pregnant women's saliva(AU)

RESUMO

The purpose of this study was to investigate the effects of preoperative oral management (POM) by dentists on the incidence of postoperative pulmonary complications (PPCs), length of hospital stay, medical costs, and days of antibiotics administration following both open and thoracoscopic esophagectomy.Dental plaque is an established risk factor for postoperative pneumonia, which could be reduced by POM. However, few clinical guidelines for cancer treatment, including those for esophageal cancer, recommend POM as routine perioperative care.We extracted data of esophagectomy cases from the Japanese Diagnosis Procedure Combination database. We subsequently conducted propensity score (PS) analyses for multilevel data, including matching, inverse probability of treatment weighting (IPTW), and standardized mortality ratio weighting (SMRW), to estimate the effect of POM by dentists on the outcomes of esophagectomy.We analyzed 3412 esophagectomy cases of which 812 were open, and 2600 were thoracoscopic surgery. In IPTW analysis to estimate the average treatment effect, the risk difference of postoperative aspiration pneumonia ranged from -2.49% to -2.02% between the POM and control groups of both open and thoracoscopic esophagectomy cases. IPTW analyses indicated that the total medical costs of thoracoscopic esophagectomy were reduced by 221,200 to 253,100 Japanese Yen (equivalent to about $2000-$2200). In PS matching and SMRW analyses to estimate average treatment effect on treated, there was no difference in outcomes between the POM and control groups.Our results suggested that in patients undergoing open or thoracoscopic esophagectomy, POM by dentists prevented the occurrence of postoperative aspiration pneumonia. It could also reduce the total medical costs of thoracoscopic esophagectomy. Thus, POM by dentists can be considered as a routine perioperative care for all patients undergoing esophagectomy, regardless of the expected risk for PPC.

RESUMO

Las estrategias tradicionales para abordar la salud bucal en México han carecido de un enfoque integrado a la promoción de la salud y a los factores de riesgo en común con otras patologías, principalmente crónicas. De unir esfuerzos se aprovecharían mejor los limitados recursos sanitarios. Esta investigación tuvo como objetivo implementar un modelo operativo de promoción de la salud y prevención de las enfermedades bucales, usando un ciclo de mejora continua en el preescolar de la comunidad Peña-Flores, Cuautla, Morelos. Se realizó un estudio cuasi-experimental con 120 niños de ambos sexos. La implementación contempló: diagnóstico epidemiológico bucal y social, capacitación de actores clave, ejecución del programa de salud bucal, monitoreo, análisis y evaluación de resultados. Se levantaron datos mediante una guía de observación participante, de reuniones con madres de familia y maestras bajo la perspectiva participativa del triple diagnóstico de educación popular. Se determinó el índice de dientes cariados, a extraer y obturados. Se realizó la medición de la placa dento-bacteriana utilizando el índice de sedimento dental (DIS). Como resultado del control y sistematización del proceso de cepillado dental y del monitoreo de la placa dento-bacteriana, se identificó una disminución del DIS de 1,04 a 0,47. Con la implementación de un menú escolar, se mejoró la alimentación infantil. El modelo implementado constituye una posible solución a la problemática de salud bucal del preescolar de la comunidad Peña-Flores, situado en un contexto de desventaja social por factores como pobreza, migración y déficit de servicios públicos(AU)

RESUMO

The goal was to assess the access and factors connected to dental visits in children up to age five in the city of Porto Alegre, Brazil. The cross-sectional study was conducted in 10 Basic Health Units through a questionnaire and clinical examination on 560 children. Clinical (visible plaque, gingival bleeding and defs), socio-demographic, and visit access variables were assessed. Poisson Regression was used to calculate the Prevalence Ratios (PR), with a 95% confidence interval. Results showed that 68.2% of children had never gone to a dentist. The main reason reported for not visiting a dentist was not feeling the need (48.7%) and difficult access to a health clinic (15.8%). The purpose of going to the dentist was for prevention/revision (55.8%), and the most sought-after places for visits were the private office (43.9%) and health clinic (39.5%). The final multivariate model showed that age of the child (95%CI, PR = 1.03 (1.02-1.05)), household income (PR = 1.05; (1.01-1.08)), and the mother having completed high school (PR = 1.69 (1.15-2.56)) were associated with seeking dental consultation. Thus, it is crucial to recognize the importance of the family setting during the first years of life.

RESUMO

INTRODUCTION: The objective of this study was to investigate the association between incisor irregularity and anterior coronal caries by means of an arch-specific analysis among the U.S. population in the National Health and Nutritional Examination Survey (NHANES III) 1988-1994. METHODS: This study analyzed data from 9049 participants who were surveyed from 1988 to 1994 as a part of the NHANES III. Participants with a complete set of fully erupted permanent anterior teeth in the maxillary and mandibular segments (ie, canine to canine), who completed an examination of occlusal characteristics and anterior dental caries, and who reported no previous orthodontic treatment were included in the study. Incisor irregularity per arch was determined with the use of the Little irregularity index. Anterior coronal caries per arch was defined as ≥1 surface with decayed or filled surface (CDFS ≥1). Analyses were conducted with the use of chi-square test and logistic regression modeling taking into account the complex sampling design of the survey. RESULTS: In the maxillary arch, 25.1% of the study population had maxillary anterior coronal caries experience (CDFS ≥1), whereas only 5.5% of the study population had mandibular anterior coronal caries experience (CDFS ≥1). In both arches, no statistically significant association between incisor irregularity and anterior coronal caries experience was found. CONCLUSIONS: Maxillary and mandibular incisor irregularity is not associated with anterior dental caries prevalence in a subset of NHANES III data that included mostly highly educated adult participants who were white, of medium socioeconomic status, and with high oral health compliance and oral self-care. Future well designed prospective cohort studies are needed to confirm these results. Clinicians are still encouraged to continue providing oral health education to their patients about the well established effect of incisor irregularity on plaque retention.

RESUMO

Resumo O objetivo foi avaliar o acesso e fatores associados à consulta odontológica em crianças de até 5 anos no município de Porto Alegre, Brasil. Estudo transversal realizado em 10 Unidades Básicas de Saúde, através de questionário e exame clínico em 560 crianças. Foram avaliadas variáveis clínicas (placa visível, sangramento gengival e ceo-s), sociodemográficas, e de acesso à consulta. Regressão de Poisson foi utilizada para cálculo de Razões de Prevalência (RP), com intervalo de confiança de 95%. Os resultados mostraram que 68,2% das crianças nunca haviam ido ao dentista. O principal motivo relatado para a não realização de consulta odontológica foi não ter sentido necessidade (48,7%) e dificuldade de acesso ao posto de saúde (15,8%). A procura pelo dentista teve como propósito a prevenção/revisão (55,8%) e os locais mais procurados para consultas foi o consultório particular (43,9%) e o posto de saúde (39,5%). O modelo multivariado final mostrou que a idade da criança (IC95%, RP = 1,03 (1,02-1,05)), a renda familiar (RP = 1,05; (1,01-1,08)) e a mãe ter concluído o ensino médio (RP = 1,69 (1,15-2,56)) estiveram associados com a procura por consulta odontológica. Assim, torna-se fundamental reconhecer a importância do contexto familiar durante os primeiros anos de vida.

RESUMO

In order to determine the association between oral health and oral hygiene conditions and nutritional status in children using a health facility in the Huánuco region, a cross-sectional descriptive study was conducted in 118 children who attended the Growth and Development Control (CRED) of the health clinic "La Esperanza." Oral health and hygiene conditions were evaluated by visible bacterial plaque, simplified oral hygiene, simplified bleeding, and gingival inflammation indices. Nutritional status was obtained from the last CRED control recorded in the clinical history. Acute malnutrition (AM) was the most common nutritional status. Among children with AM, the proportion of severe gingival inflammation was 60.3%; gum bleeding, 61.5%; dentobacterial plaque presence, 59.3%; and poor oral hygiene, 60.3%. There is evidence of a greater impact of oral health and oral hygiene on children with malnutrition, mainly acute.

RESUMO

OBJECTIVES: The identification of predictors of supragingival biofilm accumulation may improve the results of therapeutic strategies for dental caries and periodontal diseases in general clinical practice. This study aimed to determine predictors of changes in visible plaque (VP) and gingival bleeding (GB) during integrated dental care. MATERIALS AND METHODS: A retrospective longitudinal study was conducted by a census of patients receiving integrated dental care in a general clinical practice ambulatory at the Federal University of Rio Grande do Sul (Brazil). The sample comprised 91 charts of patients attended over a 6-months period. Gender, age, patient's main complaint, oral hygiene pattern, and clinical data were recorded from charts for the last two dental visits in the ambulatory. Changes in VP and GB were modeled by multiple linear regression and beta coefficients (b) were reported. RESULTS: The mean follow-up time was 13 months. Significant reductions in VP (32.8 ± 27.9 to 17.4 ± 19.4%; p < 0.001) and GB (27.1 ± 23.8 to 18.5 ± 17.3%; p < 0.001) were observed. Higher plaque reductions were predicted by higher baseline VP levels (p = 0.02), shorter time (< 12 months) elapsed between VP recordings (b = 14.1%, p = 0.02), interproximal cleansing (b = 11.9%, p = 0.03), lower number of sessions for oral hygiene instruction (b = 13.7%, p = 0.02), and presence of pockets ≥ 6 mm (b = - 12.4%, p = 0.02). GB was predicted by time of follow-up > 12 months and baseline VP. CONCLUSIONS: Plaque and gingivitis improved in patients under integrated dental care. Factors related to motivation, oral hygiene practices, and baseline periodontal status might be used as predictors of VP and GB changes. CLINICAL RELEVANCE: Visible plaque and gingivitis reduced in a sample of patients treated under integrated dental care. Some predictors may determine for which patients the treatment may be maximize and those who will need greater efforts to achieve the therapeutic goal for oral hygiene.

RESUMO

Dental caries are a process of demineralization and destruction of human teeth. They originate through many factors and are associated with biofilm formation, which consists of bacteria adhered to the teeth that form a structurally and functionally organized mass called dental plaque. Both the presence of Streptococcus mutans and the frequent consumption of sucrose correlate with a higher prevalence of caries in humans. In dogs, however, the incidence of this disease is low, due to factors such as differences in dental microbiota and/or their low consumption of sucrose. This work evaluated the antagonism of bacteria from dog's dental plaque against S. mutans, for the identification of producing strains of biotechnological products for use in preventing caries. This study used 95 bacterial isolates of canine dental plaque from the Veterinary Department at the Federal University of Viçosa, Minas Gerais, Brazil. A spot-on-the-lawn method was performed using Brain Heart Infusion agar with catalase for an initial identification of the antagonistic activity. Additional tests were conducted on the isolates classified as antagonists for confirmation of the activity, using modified Mann-Rogosa-Sharpe medium containing low dextrose concentration. These isolates were incubated at 37°C for 24 hours in anaerobiosis. The peptide nature of inhibition was evaluated using the following proteinases: proteinase K from Tritirachium album, bovine pancreatic trypsin, and type XII-A α-amylase from Bacillus licheniformis. In the initial identification of those strains exhibiting antimicrobial activity, 14 were classified as antagonists. One of the isolates (Bacillus sp.) indicated bacteriocinogenic activity, with a deformed inhibition halo on S. mutans by the addition of trypsin. These results suggest that this bacterial isolate may be applicable to biotechnological use to combat the main etiological agent of caries in humans. Further studies are needed to evaluate the bacteriocinogenic nature of the antimicrobial activities of the other 13 antagonistic bacterial isolates.

RESUMO

In order to evaluate risk factors related to the presence of extrinsic dental black stain, a total of 94 orally healthy volunteers (47 individuals with dental black stain and 47 individuals without dental black stain) were recruited from ten different dental clinics in Valencia and Castellón (Spain). Data regarding their oral hygiene, dietary habits, and oral health status were gathered by questionnaire. Samples of dental plaque, saliva and drinking water were collected for chemical analysis. Three factors were found to be statistically significantly associated with dental black stain, (i) consuming water with high iron content, (ii) consuming water with high pH, and (iii) having a high salivary pH. Other factors such as smoking, taking iron supplements or consuming caffeinated drinks were not found to be risk factors for the presence of black stain. A multivariate logistic regression analysis showed that drinking tap or osmosis-purified water and lower levels of salivary iron increase the risk of having dental black stain. Overall, several risk factors for the presence of dental black stain have been identified. The main modifiable risk factor identified in this study was the consumption of tap or osmosis drinking water.

RESUMO

This study aimed to investigate the association between socioeconomic and behavioral factors, general health, oral health, and plaque accumulation and oral mucosa condition outcomes in the elderly. This is a cross-sectional study conducted from 2004 to 2005 with 785 elderly dwellers of the city of Carlos Barbosa (RS), Brasil. We used questionnaires to collect socioeconomic, behavior and health status data. The physical examination of the oral structures comprised the Mucosal-Plaque Index proposed by Henriksen (MPS). A higher prevalence of moderate/severe plaque accumulation was observed in the elderly group, in less educated male elderly. The use of full upper dentures and income under one minimum wage were protective factors for moderate/severe plaque accumulation. Only the variables of the first block of the conceptual structure, male gender (OR = 2.13; 95% CI 1.26-3.61) and lower education (OR = 1.37; 95% CI 1.06-1.78) remained associated with an unacceptable MPS score. The findings suggest that, as per MPS, less educated male elderly are more likely to have poor oral health.

RESUMO

Limited information on the oral health status of adult heart transplant recipients (HTRs) is known, and no available data exist in China. A prerequisite dental evaluation is usually recommended for patients' postorgan transplantation because lifelong immunosuppression may predispose them to infection spread.The aim of this study was to investigate the oral health status of Chinese adult HTRs and determine the association between oral health status and history of heart transplantation (HT).We carried out a cross-sectional study to collect clinical, demographic, socioeconomic, and behavioral data from 81 adult patients who received heart transplantation during 2014 to 2015 in China. Clinical examinations for the presence of dental plaque, dental calculus, dental caries, and periodontal health conditions were performed in a standardized manner by one trained examiner. Sociodemographic, socioeconomic, and behavioral data were self-reported using questionnaires. The prevalence of the above conditions was compared with 63 age- and sex-matched controls. General liner regression analysis was used to assess associations between mean number of decayed, missing, and filled teeth (DMFT) and mean community periodontal index of treatment needs (CPITN) scores and history of heart transplant.Mean age of the HT group was 47.7 ±â€Š12.2 years and men accounted for 69.1% of the sample. The overall median DMFT score in the HT group was 3 (1-5) and caries prevalence was 80.2%, which were similar to the control group (P > .05). The overall mean CPITN score of the HT group was 1.84, which was significantly higher than the control group (1.07, P = .001). Participants in the HT group had worse oral hygiene status and more teeth with probing depth ≥ 4 mm than controls (P = .043). Compared with participants who had no history of heart transplantation, HTRs presented worse periodontal health conditions (mean CPITN score, adjusted odds ratio (OR) = 1.39, 95% confidence interval (CI) = 1.12-1.71, P = .003) and similar dental caries status (DMFT score, adjusted OR = 0.58, 95% CI = 0.37-0.91, P = .058).Periodontal health status was positively associated with history of heart transplantation in Chinese adult HTRs.

RESUMO

OBJECTIVE: Given the high prevalence of caries and periodontal disease globally, and its cumulative process from an early age, effective strategies are required to influence healthy habits that are formed in a sustainable manner, taking advantage of common spaces such as school. The objective was to evaluate for 72 months an oral health prevention strategy in schoolchildren. METHODS: This quasi-experimental study considered an initial sample of 350 students with similar cultural and socioeconomic conditions, which was later reduced to 220, after the 72 months. The tooth brushing practice was carried out at school daily; with teacher motivation and leader in oral health formation. Intervention was supervised all time long. to At the beginning and end of the 72 months, the following epidemiological indexes were taken: Silness-Loe plaque index, Loe-Silness Gingival index, brushing skill index by Simmons Smith & Gelbie (ISSG), and the MEDI-MED index that dichotomically considered: healthy permanent teeth, health of the gums and good attitude towards dental health. The statistical analysis included measures of central tendencies. The difference in averages of the indices was determined by the Mann-Whitney U test. RESULTS: The average of the indices: initial (II) and final (IF) registered as follows: gingival (II: 0.63-IF: 0.27) and bacterial plaque (II: 0.99-IF: 0.41) with a difference p <0.05. The index (ISSG) indicated a dental plaque removal of 82.18%.MEDI-MED index "healthy permanent teeth" (II: 91% - IF: 59%); Gum (II: 14% - IF: at 85%) and the "Mind" component (II: 96% - IF: 87%). CONCLUSIONS: The preventive strategy evaluated significantly reduced the rates of bacterial and gingival plaque. The MEDI-MED index indicated decreased in healthy permanent teeth and a positive attitude towards dentistry.

RESUMO

BACKGROUND: The objectives of this study were to determine the status of oral health among newly arrived refugees in Germany and to explore their knowledge, attitude and practices on oral hygiene. METHODS: All participants (n = 386) were adults, 18-60 years of age, coming from Syria and Iraq and registered as refugees in Germany within one year prior to the enrollment in the study. Clinical oral assessments in addition to a survey on knowledge, attitude and practice were carried out. The survey was conducted through a questionnaire translated into Arabic. RESULTS: Eighty seven point 5 % of the participants had untreated caries. The mean DMFT score was 6.38 with DT, MT and FT showing mean scores of 4.00, 1.46 and 0.92 respectively. Seventy nine percent had bacterial plaque in all six sextants, 60 % had calculus in at least three sextants and 6 % showed various magnitudes of enamel fluorosis. DMFT score was significantly associated with age (Regression Coefficient 0.031, P-value < 0.001) and with education (Regression Coefficient - 0.019, P-value 0.037) and females had significantly less missing teeth (Regression Coefficient-0.398, P-value 0.001) compared to males. The participants had in general high levels of knowledge and attitude on oral hygiene. The findings however showed a gap between their knowledge and practice. CONCLUSIONS: The findings show high prevalence of untreated caries and poor oral hygiene among newly arrived refugees in Germany. The study recommends to lay emphasis on motivation in oral health promotion campaigns among refugees and to provide them with adequate guidance, preferably in their native language, on how to access oral health care in the host country.

RESUMO

PURPOSE: To evaluate plaque accumulation, peri-implant soft tissue inflammation, and bone resorption in patients with immediately loaded implants supporting fixed full-arch prostheses. MATERIALS AND METHODS: A convenience sample of 72 patients treated with fixed full-arch prostheses supported by four to six immediately loaded implants was selected. Bleeding on probing (BOP), Plaque Index (PI), and peri-implant bone loss were measured. The Sixth European Workshop on Periodontology definitions of mucositis and peri-implantitis were used, and collected data were analyzed using a nonparametric test (Spearman's rank correlation). Correlation coefficients (ρ) were defined as follows: < 0.2 = very weak; 0.2 to 0.39 = weak; 0.4 to 0.59 = moderate; 0.6 to 0.79 = strong; 0.8 to 1.0 = very strong. RESULTS: A total of 331 implants were analyzed. The mean follow-up observation time was 5.8 years (range: 1 to 14 years); mean PI and BOP were 61.7% and 21.1%, respectively; and mean bone loss was 0.89 mm (standard deviation [SD] 1.09). The mean probing depth was 1.8 mm (range: 0.5 to 5 mm). Five patients presented with one implant each affected by peri-implantitis (6.9%), and 15 patients presented with at least one implant affected by mucositis (20.8%). No correlation was found between PI and bone resorption (P = .08). Very weak correlations were found between BOP and bone resorption (ρ = 0.18; P = .001) and between PI and BOP (ρ = 0.13, P = .019). CONCLUSION: The results suggest that plaque accumulation is correlated with peri-implant mucositis; however, plaque accumulation alone does not appear to be associated with bone resorption.
