RESUMO

BACKGROUND: To evaluate the predictive performance of self-reported questions for periodontitis screening in a representative sample of a rural population. METHODS: Nine questions were compared with gold standard clinical examinations (probing six sites/tooth, full-mouth). Case definition for severe periodontitis was defined according to World Workshop (2017-WW) and Centers for Disease Control and Prevention/American Academy of Periodontology (CDC/AAP). Diagnostic tests such as sensitivity (SN), specificity (SP), positive and negative predictive values were performed for all questions alone and grouped into models. Binary logistic regression modeling was used to derive parameter estimates for all variables in a given model and the area under ROC curve was calculated. RESULTS: Clinical examinations showed a prevalence of periodontitis in the sample (n = 585) of 99.4% and 86.3%, being 40.3% and 33.8% of severe disease according to 2017-WW and CDC/AAP case definitions, respectively. Individually, only the questions regarding the self-perception of teeth/gum health and loose and lost teeth were valid to predict severe periodontitis. The best logistic regression models combined sociodemographic variables and risk-factors with the self-reported measures of self-perception of gum disease, teeth/gum health, loose teeth and history of tooth loss. CONCLUSION: Predictive performance of these self-reported questions presented herein support its potential use for surveillance of severe periodontitis in rural populations with high periodontitis prevalence.

RESUMO

OBJECTIVE: To describe the sampling strategy of an epidemiological survey with the aid of satellite images, including details of the multistage probability sampling process. METHODS: A probability sample of individuals living in the rural area of Rosário do Sul, state of Rio Grande do Sul, Brazil, aged 15 years old or more, was evaluated. Participants answered questionnaires (medical history, sociodemographic characteristics, habits, alcohol use, quality of life, stress, rumination, and self-perceived periodontal diseases), and were subjected to clinical oral examinations as well as anthropometric measurements (blood pressure, height, weight, abdominal and waist circumferences). Oral evaluation comprehended a complete periodontal exam at six sites per tooth, including the following assessments: furcation involvement; dental abrasion; tooth decay, including the indexing of missing and filled surfaces; O'Brien index; gingival abrasion; oral cavity and lip lesions; complete periapical radiographic exam, and use of prostheses. Besides this oral clinical approach, subgingival plaque, crevicular gingival fluid, saliva, and blood samples were collected. Examiners were trained and calibrated during previous evaluations. A pilot study allowed the logistic of the performed exams to be adjusted as needed. RESULTS: Among 1,087 eligible individuals, 688 were examined (63.3%). Age, sex, and skin color data were compared to data from the last demographic census (2010) of the Brazilian Institute of Geography and Statistics, which served to validate the sampling strategy. CONCLUSIONS: The careful methods used in this study, in which satellite images were used in the delimitation of epidemiological areas, ensure the quality of the estimates obtained and allow for these estimates to be used in oral health surveillance and health policies improvements.

RESUMO

OBJECTIVES: To evaluate the correlation between dental plaque formation and gingival health in subjects performing high oral hygiene standards over short or extended intervals. MATERIALS AND METHODS: Fifty-two non-dental students volunteered for this study. The subjects, trained to perform high oral hygiene standards, were randomized to perform oral hygiene at 12-, 24-, 48-, or 72-h interval over 30 days. The plaque index (PlI) and the gingival index (GI) were evaluated at baseline, 15, and 30 days. For the statistical analysis, oral hygiene intervals were collapsed into daily (12 and 24 h; G12/24) and extended (48 and 72 h; G48/72) intervals. Summary statistics (mean ± SD) and Spearman correlations between the PlI and the GI at baseline, 15, and 30 days were estimated. RESULTS: At baseline, correlation coefficients between PlI and GI were positive for both groups (r = 0.29 and r = 0.25). At day 15 and 30, correlation was maintained with similar baseline values for the G48/72 group. GI levels did not increase despite an increase in PlI for the G12/24 group, and the correlation was lower than that observed at baseline (r = 0.13 vs. r = 0.29). CONCLUSIONS: In subjects with high oral hygiene standards, the oral hygiene frequency governs the correlation between dental plaque formation and gingival health. Subjects performing high oral hygiene standards at daily intervals will maintain gingival health in difference to subjects using extended hygiene intervals. CLINICAL RELEVANCE: Subjects performing high oral hygiene standards at daily intervals will maintain gingival health in difference to subjects using extended hygiene intervals.

RESUMO

The aim of the present study was to compare negative impacts of oral conditions in Oral Heath Related Quality of Life (OHRQoL) assessed by the Oral Health Impact Profile-14 (OHIP-14) scores in pregnant women receiving or not comprehensive periodontal treatment. This randomized controlled clinical trial included pregnant women aged between 18 and 35 years old. Participants were randomized in a test group with 96 and a control group with 114 women. Patients in the test group received comprehensive periodontal treatment, supra and subgingival scaling and root-planning and periodontal maintenance appointments. The OHIP-14 was applied before and after treatment. The primary outcome was changes in OHIP-14 scores after follow-up period. The impact of having received or not comprehensive periodontal treatment on the change of the OHIP-14 scores was also investigated. Both groups showed significant reduction in OHIP-14 scores and effect size for the test group was 0.60 and 0.36 for the control group. Multinomial logistic regression analysis showed that participants of the control group had 5.9-fold odds (CI 95% 1.88-18.52) of worsening in OHIP-14 scores and their perception of oral conditions in relation to test group. Comprehensive periodontal treatment during pregnancy can reduce the negative impacts in OHRQoL.

RESUMO

OBJECTIVE: The aim of this study was to assess the associations of gingival bleeding with individual and community social variables among schoolchildren. METHODS: This cross-sectional study evaluated a representative, multistage, random sample of 1,134 12-year-old schoolchildren from Santa Maria, a city in southern Brazil. The participants were examined clinically, and full-mouth gingival bleeding was recorded according to the Community Periodontal Index criteria (scored as healthy or bleeding). The children's parents or guardians answered questions regarding their socioeconomic status and social capital, and an assessment of the associations was performed using multilevel Poisson regression models. RESULTS: The prevalence of gingival bleeding was 96.21 percent. The multilevel adjusted assessment revealed that socioeconomic, clinical, and social capital variables at the individual level were associated with higher levels of gingival bleeding. Children whose fathers had a low educational level, children who had dental plaque and dental crowding, and children who never/almost never attended religious meetings exhibited significantly higher levels of gingival bleeding than their counterparts. This social gradient remained significant even after adjusting for contextual-level covariates. CONCLUSION: The results indicate that the socioeconomic status and features of social capital are associated with the levels of gingival bleeding among schoolchildren.

RESUMO

Introdução: Estudos sugerem a relação entre doença periodontal e condições sistêmicas, dentre elas o câncer. A plausibilidade biológica desta possível associação é o aumento de marcadores inflamatórios na corrente sanguínea devido a uma infecção crônica. Objetivo: Revisar a literatura sobre a associação entre a condição periodontal e câncer em sítios específicos, bem como analisar a influência de fatores de risco e confundimento nessa inter-relação. Materiais e Métodos: A busca da literatura foi realizada na base de dados PubMed, utilizando as palavras-chave: "periodontal diseases"; "tooth loss"; "inflammation"; "risk factors" e "cancer". A busca foi limitada a artigos a partir do ano 2000, com delineamento caso-controle e coorte incluindo seres humanos. Resultados: Alguns estudos demonstraram associações estatisticamente significantes entre avaliações das medidas periodontais e/ ou a perda dentária, principalmente para o câncer oral e do trato gastrointestinal superior, além do câncer de mama, hematológico, de pâncreas e de pulmão, em diferentes populações. Essas associações persistem em alguns estudos mesmo após o ajuste para fatores de risco como o fumo, a condição socioeconômica e o consumo de álcool. Conclusões: Esta revisão de literatura sugere que o quadro inflamatório associado às doenças periodontais tem um possível papel no processo de carcinogênese, independente de outros fatores de risco associados. Porém, nenhum estudo apresentou resultados conclusivos sobre influência do quadro inflamatório periodontal na carcinogênese.(AU)


Introduction: Studies suggest the relationship between periodontal disease and systemic conditions, among them cancer. The biological plausibility of this possible association is the increase in inflammatory markers in the bloodstream due to a chronic infection. Aim: To review the literature about the association between periodontal status and cancer at specific sites and to analyze the influence of risk factors and confounding in this interrelationship. Methodology: The literature search was conducted in PubMed database using the keywords: "periodontal diseases"; "tooth loss"; "inflammation"; "risk factors" and "cancer". The search was limited to articles from 2000, with case-control and cohort including humans. Results: Some studies have shown statistically significant association between periodontal evaluation of measures and/ or tooth loss, especially for oral and upper gastrointestinal tract cancer, and breast cancer, hematologic, pancreas and lung, in different populations. These associations persist in some studies even after adjusting for risk factors such as smoking, socioeconomic status and alcohol consumption. Conclusion: This literature review suggests that the inflammatory process associated with periodontal disease have a possible role in the carcinogenesis process, independent of other risk factors. However, no study showed conclusive results about the influence of periodontal inflammatory process in carcinogenesis. (AU)

RESUMO

This study evaluated the clinical diagnosis of proximal gingivitis by comparing two methods: dental flossing and the gingival bleeding index (GBI). One hundred subjects (aged at least 18 years, with 15% of positive proximal sites for GBI, without proximal attachment loss) were randomized into five evaluation protocols. Each protocol consisted of two assessments with a 10-minute interval between them: first GBI/second floss, first floss/second GBI, first GBI/second GBI, first tooth floss/second floss, and first gum floss-second floss. The dental floss was slid against the tooth surface (TF) and the gingival tissue (GF). The evaluated proximal sites should present teeth with established point of contact and probing depth ≤ 3mm. One trained and calibrated examiner performed all the assessments. The mean percentages of agreement and disagreement were calculated for the sites with gingival bleeding in both evaluation methods (GBI and flossing). The primary outcome was the percentage of disagreement between the assessments in the different protocols. The data were analyzed by one-way ANOVA, McNemar, chi-square and Tukey's post hoc tests, with a 5% significance level. When gingivitis was absent in the first assessment (negative GBI), bleeding was detected in the second assessment by TF and GF in 41.7% (p < 0.001) and 50.7% (p < 0.001) of the sites, respectively. In the absence of gingivitis in the second assessment (negative GBI), TF and GF detected bleeding in the first assessment in 38.9% (p = 0.004) and 58.3% (p < 0.001) of the sites, respectively. TF and GF appears to be a better diagnostic indicator of proximal gingivitis than GBI.

RESUMO

Two previous clinical studies evaluated the effect of end-rounded versus tapered bristles of soft manual brushes on the removal of plaque and gingival abrasion. However, the combined effect of an abrasive dentifrice on these outcomes has yet to be understood. The purpose of the present study was to compare the incidence of gingival abrasion and the degree of plaque removal obtained after the use of toothbrushes with tapered or end-rounded bristles in the presence or absence of an abrasive dentifrice. The study involved a randomized, single-blind, crossover model (n = 39) with a split-mouth design. Subjects were instructed to refrain from performing oral hygiene procedures for 72 hours. Quadrants were randomized and subjects brushed with both types of toothbrushes using a dentifrice (relative dentin abrasion = ± 160). Plaque and gingival abrasion were assessed before and after brushing. After 7 days, the experiment was repeated without the dentifrice. The average reduction in plaque scores and the average increase in the number of abrasion sites were assessed by repeated-measures ANOVA and Bonferroni's post-hoc tests. End-rounded bristles removed significantly more plaque than tapered bristles, regardless of the use of a dentifrice. The dentifrice did not improve plaque removal. In the marginal area (cervical free gingiva), no difference in the incidence of gingival abrasion was detected between toothbrush types when used with a dentifrice (p ≥ 0.05). However, the dentifrice increased the incidence of abrasion (p < 0.001), irrespective of the toothbrush type tested. End-rounded bristles therefore removed plaque more effectively without causing a higher incidence of gingival abrasion when compared with tapered bristles. An abrasive dentifrice can increase the incidence of abrasion, and should be used with caution by individuals who are at risk of developing gingival recession.

RESUMO

AIM: To evaluate the effect of self-performed mechanical plaque control (SPC) frequency on gingival health. METHODS: Thirty-nine subjects exhibiting limited gingival inflammation and minimal clinical attachment loss were enrolled in a single-blind, parallel group, randomized clinical trial. The subjects that were divided into three groups were tasked to perform SPC (using tooth brush and dental floss) at 12, 24 or 48 h intervals. Gingival index (GI), plaque index (PlI), and gingival crevicular fluid (GCF) volume were evaluated at baseline and 30 days follow-up. Groups were compared using anova and Tukey. RESULTS: No significant differences in mean GI change were observed between the 12 and 24 h SPC intervals from baseline to 30 days (-0.06 ± 0.13 versus 0.05 ± 0.09; p = 0.11). In contrast, the 48 h interval had significantly higher mean GI change than the 12 and 24 h intervals (0.33 ± 0.17; p = 0.001). Similarly, mean PlI change was not significantly different between the 12 and 24 h SPC intervals (0.11 versus 0.28; p = 0.15), whereas SPC at 48 h-intervals yielded a significantly increased PlI (0.39; p = 0.001). CONCLUSIONS: Self-performed mechanical plaque control performed at 12 h or 24 h intervals appears sufficient to maintain gingival health in subjects with no or limited clinical attachment loss.

RESUMO

Introduction Smoking is a risk factor for prevalence, severity and progression of periodontal disease and appears to suppress marginal periodontium inflammatory response. Purpose To correlate Visible Plaque Index (VPI) and Gingival Bleeding Index (GBI) in smokers and never-smokers, as well as GBI and bleeding on probing (BOP ) in these groups. Material and method We used baseline data of one quasi-experimental study in which 11 smokers and 14 subjects who never smoked were submitted to clinical periodontal examinations between September 2010 and October 2011. Result The correlation between VPI and GBI was positive for both groups, it was strong and statistically significant in subjects who had never smoked and moderate in smokers. Regarding GBI and BOP correlations were moderate for smokers and weaker for individuals who had never smoked. Conclusion Smokers have lower strength correlation between VPI and GBI compared to individuals who had never smoked resulting in a less pronounced marginal gingival bleeding. .


Introdução O hábito de fumar é um fator de risco importante na prevalência, progressão e gravidade das doenças periodontais e parece suprimir a resposta inflamatória marginal no periodonto. Objetivo Correlacionar Índice de Placa visível (IPV) e Índice de Sangramento Gengival (ISG) em fumantes e indivíduos que nunca fumaram, bem como correlacionar ISG e o sangramento à sondagem (SS) nesses dois grupos. Material e método Foram utilizados dados de baseline de um estudo quasi-experimental, no qual 11 pacientes fumantes e 14 indivíduos que nunca fumaram foram submetidos a exames clínicos periodontais no período de setembro de 2010 e outubro de 2011. Resultado A correlação entre IPV e ISG foi positiva para ambos os grupos, sendo forte e estatisticamente significante nos indivíduos que nunca fumaram e moderada nos fumantes. Com relação ao ISG e SS houve moderada correlação para os fumantes e fraca para os indivíduos que nunca fumaram. Conclusão Fumantes apresentam uma correlação entre IPV e ISG de menor força em relação aos indivíduos que nunca fumaram resultando em um sangramento gengival marginal menos pronunciado. .

RESUMO

OBJECTIVE: This study was conducted to compare periodontal therapy outcomes during pregnancy and after delivery. MATERIALS AND METHODS: One hundred nine pregnant women up to the 20th gestational week (GW) were randomized into two groups: the test group (comprehensive periodontal therapy during pregnancy) and the control group (comprehensive periodontal therapy after delivery). Periodontal examinations comprised plaque index (PI), gingival index (GI), periodontal probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and gingival crevicular fluid (GCF) volume. After baseline examination, women in the test group received periodontal treatment up to the 24th GW. The final examination was performed at the 26th to the 28th GW. Women in the control group were treated 30 days after delivery and reexamined 30 days after treatment. RESULTS: Periodontal therapy significantly reduced periodontal inflammation in both groups. The mean percentage of sites with BOP was reduced from 49.14 % (±22.49) to 11.10 % (±7.84) and from 45.71 % (±17.86) to 8.07 % (±5.21) in the test and control groups, respectively (p = 0.95). No statistically significant differences were observed between groups concerning PI, GI, PPD, CAL, and GCF. The reduction in mean percentage of sites with BOP stratified for initial PPD ≥4 mm was higher in the control group (p < 0.01), but no differences were seen regarding GCF in these sites. CONCLUSIONS: Hormonal changes during pregnancy do not interfere in treatment outcomes in women with widespread gingival inflammation and limited periodontal destruction. The role of these hormonal changes in pregnant women with different disease patterns remains uncertain. CLINICAL RELEVANCE: Periodontal health can be reestablished irrespective of the hormonal challenge that takes place during pregnancy.

RESUMO

The objective of this study was to evaluate the effect of smoking on response to nonsurgical periodontal therapy using the primary outcome measure of bleeding on probing (BoP). An periodontist performed periodontal therapy on 11 smokers and 14 never smokers with periodontitis. Two examiners assessed visible plaque index, gingival bleeding index, probing pocket depth (PPD), BoP, suppuration on probing and clinical attachment level (CAL), at baseline and three months after therapy. BoP was categorized as 0 (absent), 1 (small bleeding point) and 2 (blood flow from the sulcus). Total BoP value was obtained by summing values of 1 and 2. All subjects had significant reductions in mean PPD and percentages of sites with BoP, with no difference between the groups. Only never smokers presented statistically significant CAL gain. BoP was significantly and consistently reduced at sites with initial PPDs of 1-3 mm and 4-6 mm in both groups. At sites with deep PPD ( ≥ 7mm), never smokers showed a greater mean reduction in the number of sites with BoP than did smokers (p < 0.05). Never smokers had significantly greater reduction in BoP 2 than smokers, at sites with moderate and deep baseline PPDs. The first group had a significant increase of BoP 1, at sites with initial PPDs of 4-6 mm. Thus, periodontal therapy reduced BoP in both groups. However, smoking could negatively affect the BoP reduction at deeper sites after nonsurgical periodontal therapy.

RESUMO

This study used cone beam computed tomography (CBCT) to evaluate distances among root surfaces in molar furcations and assess the congruence between inter-root distances in molar furcations and curette blade widths. Distances among root surfaces at 1 and 3 mm from the fornix of molar furcations (points A and B, respectively) were measured with standardized CBCT images and analyzed using computer software. Periodontal curette widths were evaluated by digital caliper and stereomicroscope (magnification 10x). Forty CBCT images (containing a total of 141 molar teeth and 354 furcations) were evaluated; 19 furcations (5.4%) with fused molars were excluded. Mesial furcations of the first molars had the highest average inter-root distances (point A: 3.81 ± 0.87 mm; point B: 5.30 ± 0.92 mm), while buccal furcations of the maxillary second molars had the smallest average distances (point A: 1.49 ± 0.37 mm; point B: 1.90 ± 0.65 mm). Analysis of 107 curettes revealed statistically significant differences among curette types and manufacturers. Pearson's coefficient revealed a strong and significant correlation for curette measurement using digital caliper and stereomicroscope (r = 0.86, P < 0.01). In most cases, the curettes tested allowed access for scaling and root planing of teeth with furcation involvement.

RESUMO

A doença periodontal está entre as principais doenças que podem afetar a cavidade bucal e é uma das causas mais expressivas de perda dentária no mundo. Sabe-se que, na maioria das pessoas, com medidas preventivas e terapêuticas adequadas há a possibilidade de manutenção dos dentes na cavidade bucal em conforto e função por toda a vida. O objetivo do presente estudo foi avaliar o nível de ligamento periodontal remanescente em dentes extraídos, recolhidos no gabinete odontológico da Secretaria Municipal de Rosário do Sul-RS. Consiste em um estudo piloto, realizado por meio de coleta de dentes extraídos no período de um mês. Fichas contendo gênero, idade e motivo da extração foram preenchidas pelo dentista e recolhidas juntamente com os dentes. Trinta e oito dentes foram corados e avaliados microscopicamente para a verificação de quanto apresentavam de inserção periodontal. A média da área de ligamento periodontal residual foi de 53,83%. A maior parte dos dentes apresentou coroa íntegra ou pequena destruição coronária e doença periodontal foram a principal razão encontrada para as exodontias. Pode ser concluído que uma quantidade significativa de ligamento periodontal residual foi observada. Porém, por ter sido este um estudo piloto, outros estudos são necessários para que os resultados sirvam de base para o planejamento de tratamento periodontal no atendimento público de saúde.


Periodontal disease is among the major diseases that can affect the oral cavity and it is one of the most significant causes of tooth loss in the world. It is known that with appropriate preventive and therapeutic measures is possible to maintain the teeth in the oral cavity in comfort and function throughout life for most people. The aim of this study was to evaluate the level of remaining periodontal ligament in extracted teeth, collected in the dental office of Secretaria Municipal de Saúde de Rosário do Sul – RS. It consists of a pilot study, conducted through the collection of extracted teeth in a month. Records containing gender, age and reason for extraction were filled by the dentist and collected together with the teeth. Thirtyeight teeth were stained and evaluated microscopically for verification of how much periodontal attachment they had. The mean residual area of the periodontal ligament was 53,83%. Most of the teeth was fully crown or small coronal destruction and periodontal disease is the main reason found for extractions. It can be concluded that a significant amount of residual periodontal ligament was observed. However, because it was a pilot study, further studies are needed to make results as a basis for planning periodontal treatment in public health care.

RESUMO

AIM: This cross-sectional study evaluated periodontal status in patients with leukaemia and its correlation with haematological parameters. METHODS: Patients with different types of leukaemia and minimum age of 14 years were eligible. Calibrated examiners assessed Seymour index (SI), plaque index (PlI), gingival index (GI), probing depth (PD), bleeding on probing (BOP) and clinical attachment loss (CAL) and performed an interview. Haematological parameters were obtained from haemogram performed on the same day of the periodontal examinations. RESULTS: Sixty-eight patients were evaluated, which corresponded to an 85% response rate. Periodontal parameters were in agreement with plaque accumulation (PlI 1.28 ± 0.5, GI 0.74 ± 0.4, PD 2.27 ± 0.6, BOP 33%, CAL 2.31 ± 1.6). PlI and CAL were statistically lower in acute leukaemia (1.13 ± 0.61 and 1.96 ± 1.7) in comparison with chronic leukaemia (1.46 ± 0.44 and 2.74 ± 1.4). Moreover, older age (95% confidence interval [CI]: 0.27-1.56), higher educational level (CI: -1.94 to -0.64) and smoker (CI: 0.39-1.96) were associated with CAL. Correlation between periodontal and haematological parameters was not observed. Correlations between GI x SI and PD x SI were statistically significant (r(S) = 0.390, p = 0.001; r(S) = 0.517, p = 0.000 respectively). CONCLUSIONS: Periodontal parameters were consistent with plaque accumulation and did not correlate with haematological parameters irrespective of the leukaemia type.
