Periodontal Health among Individuals with Intellectual Disabilities Living in a Saudi Institutional Rehabilitation Centre.

The aim of this study was to explore periodontal health among intellectually disabled individuals living in an institutional rehabilitation centre in the Al-Baha Region of Saudi Arabia. A cross-sectional study was conducted from November 2023 to January 2024. Clinical oral examinations were carried out using the World Health Organization criteria for bleeding sites and the presence of periodontal pockets. Simplified oral hygiene and community periodontal indices were employed to evaluate participants' oral health. A total of 89 participants, comprising both males and females with intellectual disabilities, were included in this study. Gender, severity of intellectual disability, type of additional physical disability, tooth brushing habits and oral hygiene status were significantly associated with the presence of periodontal disease. Additionally, poor oral hygiene, not brushing teeth and periodontal pockets of 4-5 mm and 6 mm or more were significantly more prevalent among individuals with severe and moderate intellectual disabilities (p = 0.001, p = 0.001, p = 0.001 and p = 0.001, respectively). The prevalence of periodontal disease among the studied population was 54%. The odds of having periodontal disease were significantly higher in the severe intellectual disability group compared to the mild intellectual disability group (OR = 2.328, 95% CI = 1.430-3.631, p = 0.03). It was also found that intellectually disabled participants with additional physical disabilities suffered more from periodontal disease than those without additional physical disabilities (OR = 0.971, 95% CI = 0.235-4.023, p = 0.025). Overall, individuals with intellectual disabilities had a significant demand for periodontal care. This study highlighted the need for more organised preventive programmes for individuals with intellectual disabilities. Dentists should be vigilant about improving periodontal health, focus on preventive programmes and provide comprehensive dental care with an emphasis on periodic recall and monitoring.

Evaluation of Periodontal Status and Serum C-Reactive Protein Levels in Adult Cigarette Smokers

Background: This study aimed to evaluate the periodontal status of adult smokers and assess their serum C-reactive protein (CRP) levels, hypothesizing an association between periodontal inflammation, smoking, and elevated serum CRP, a marker for cardiovascular diseases. The primary objective is to contribute to the assessment and prevention of potential cardiovascular diseases in adult smokers. Methods: This cross-sectional study was conducted at HIT Hospital and Dental Hospital HITEC-IMS Taxila Cantt over five months from October 20, 2021, to March 31, 2022, the study included 60 healthy male adult smokers and 20 healthy male non-smokers as a control. Basic periodontal examination involved the use of a periodontal probe, assessing parameters such as gingival index, bleeding on probing, oral pigmentation, presence of periodontal pockets, and gingival recession. Blood samples were collected to evaluate serum CRP levels. Results: Smokers exhibited higher rates of gingival recession (38.3%), gingival pigmentation (43.3%), and periodontal pocket formation (33.3%) compared to the nonsmokers control group, with significant p-values of 0.040 in gingival recession and 0.035 in the presence of periodontal pockets. Serum CRP levels were significantly elevated in adult smokers, with a significant p-value of 0.024. Conclusion: The study concluded that adult smokers show signs of periodontitis, and their serum CRP levels are elevated. Assessing periodontal status and serum CRP in adult smokers may aid in risk assessment and reducing the likelihood of developing future cardiovascular diseases.

Comparative analysis of the effect of 4MATRIX with and without PRF on regeneration of infrabony periodontal pockets

AimThe aim was to compare the effect in improvement of periodontal pocket depth (PPD) and clinical attachment level (CAL) between application of 4MATRIX and 4 MATRIX combined with PRF in advanced periodontal disease during follow-up of 6, 12 and 18 months. MethodsThirty patients of both genders aged 25–50 years were included. The patients were clinically and radiologically diagnosed with generalized advanced chronic periodontitis with the presence of periodontal pockets with a depth of ≥ 5 mm bilaterally in the upper jaw. Both sides were treated with a flap intervention in all patients. On one side a bone substitute 4MATRIX was applied, and the other side was treated with an application 4MATRIX and PRF. The clinical assessment and measurements were performed in four stages, immediately before the intervention, and then 6, 12 and 18 months after the intervention. PPD and CAL were determined in all four timepoints. ResultsPPD was the highest at zero time before the surgery for both groups and was 5.56 ± 0.28 mm. In the postoperative follow-up period, the PPD value decreased gradually with the lowest average value of 5.10 ± 0.18 mm after 18 months in Group I and 4.67 ± 0.13 mm in Group II (p < 0.001, respectively). Moreover, comparing the values of PPD at 6, 12 and 18 months after the surgery, a significant difference was found between the patients from the 4MATRIX vs 4MATRIX + PRF (p < 0.001 respectively). The postoperative follow-up period showed a decrease in CAL value with the lowest value after 18 months. A significant difference in CAL was found between the four measurement times (p < 0.001, respectively). The average level of CAL was the highest before surgical treatment in both groups. The intergroup analysis of CAL after 18 months in group I (4MATRIX) was 5.27 ± 0.17 mm and in group II 4.10 ± 0.14 mm (p < 0.001). ConclusionTreatment of adult patients with advanced chronic periodontitis with periodontal pockets of ≥ 5 mm bilaterally in the upper jaw using 4MATRIX and 4MATRIX + PRF showed improvement of PPD and lower CAL loss after 18 months of the treatment. In the group treated with 4MATRIX + PRF patients showed the highest improvement in PPD and CAL loss. The analysis of treatment with 4MATRIX and 4MATRIX + PRF showed the lowest values after 18 months of the treatment.

Could Periodontitis Aggravate Psoriasis?—An Update by Systematic Review

(1) Background: Psoriasis is a chronic and inflammatory systemic disease that has been associated with periodontal pathologies, specifically periodontitis. The aim of this research is to answer the following question: Could periodontitis aggravate psoriasis? (2) Methods: We carried out a systematic review following the PRISMA guide using PubMed, Embase, Scopus, and WOS; (3) Results: A total of 111 studies were identified in the databases and 11 were obtained after screening. The selection included nine case–control studies, one cross-sectional study, and one cohort study. Most of the publications report an increase in bleeding on probing and the presence of periodontal pockets in patients with psoriasis, confirming that inflammation caused by periodontitis can contribute to systemic inflammation worsening psoriasis. To summarize, the scientific literature indicates that local periodontal inflammation could aggravate psoriasis.

Pulp survival and periodontal healing of autotransplanted teeth: a retrospective study

Aim: The aim of this retrospective study was to evaluate the post-surgical results of autotransplanted teeth, considering the pulp survival rate and periodontal healing. Methodology: Records of 43 patients with 50 autotransplanted teeth were analysed. Demographic, clinical and radiographic data were verified. The time between autotransplantation surgery and the date of endodontic access was considered to assess the pulp survival rate. Periodontal healing was observed through gingival morphology and the presence of root resorption. Pulp survival was verified and the influence of Nolla stage on the survival rate was analysed. Results: The pulp survival rate was 72%, and the stage of root development influenced the survival rate in autotransplanted teeth (p = 0.001). The pulp survival rate in autotransplanted teeth in Nolla stages 6 and 7 was 100%; the pulp survival rate for teeth in stages 8 and 9 was 90% and 75%, respectively. Regarding periodontal analysis, no tooth was observed in the presence of periodontal pockets and mobility above grade I. Replacement resorption was diagnosed in 20% and external inflammatory resorption in 4%. Conclusions: Dental autotransplantation was a safe treatment, showing satisfactory results. The pulp survival rate was considered high, especially in teeth with incomplete rhizogenesis.

Periodontal Disease Diagnosis in the Context of Oral Rehabilitation Approaches

Periodontal diseases generally correspond to a disturbance in the balance between the host’s defense and the micro-organisms colonizing the periodontal environment. The exact mechanisms underlying the destruction of the periodontium remain to be fully elucidated. Our study aims to quantify the main bacteria pool involved in periodontal pathology and associate it with other factors involved in the onset of periodontal disease so that an accurate diagnosis with profound implications for the therapeutic algorithm can be developed. Micro-Ident tests, based on the polymerase chain reaction (PCR) technique, were used for the study group, chosen for their high specificity in identifying periodontopathogenic bacteria and determining their relative numbers. The results of our study indicate an increased concentration of 4.50 (number of strains) for Capnocytophaga, followed by Tannerella forsythia, in a concentration of 3.50; the next highest concentration percentages are for Treponemei denticola, and Prevotela intermedia, low concentrations were found for Fusobacterium nucleatum and Porphyromonas. The concentration of each type of bacteria is reflected in the clinical picture and constitutes the starting point for a targeted antibiotic therapy. Following the effects of antibiotic-targeted therapy obtained from the evaluation of the micro-IDent B test results on the periodontium of the supporting teeth, we observed that the values of the periodontal indices change slightly at 3-month intervals with a predominance of plaque, bleeding, and gingival indices, and less in the indices concerning the depth of the probing pocket and the loss of attachment on the buccal and oral surfaces. In conclusion, our study emphasizes a direct relationship between the subgingival tartar presence and the patients age, gingival recession, presence of periodontal pockets, dental mobility, as well as the periodontal indexes: plaque index, bleeding index, and gingival index. The correlation of negative values of periodontal indices with the nature of the involved bacteria materializes in relevant starting points in the elaboration of the periodontal diagnosis of the therapeutic plan and predictability of the prognosis of oral rehabilitation.

Relationship Between Periodontal Disease and Glycemic Control in Pediatric Patients with Type 2 Diabetes Mellitus

IntroductionType 2 Diabetes Mellitus (T2DM) is a disease of heterogeneous etiology, in which the patient presents alterations in metabolism, which are associated with a total or relative deficiency in insulin production and variable degrees of resistance to it1,2.T2DM and periodontal disease are chronic diseases, the evidence suggests an association between the two. Studies report that T2DM worsens the periodontal disease and glycemic control plays a fundamental role in this3.4.ObjectiveTo determine the relationship between periodontal disease and glycemic control in pediatric patients with T2DM.MethodologyAn observational, descriptive, cross‐sectional, prospective, homodemic and single‐center study was carried out in the pediatric stomatology service of the “Hospital para el Niño Poblano” (Puebla city, Mexico) in the period January‐July 2019 with 20 patients (between 6 to 18 years old) diagnosed with T2DM and were under treatment for their glycemic control.ResultsThe population was classified into patients with glycemic control based on glycated hemoglobin (HbA1c ≤ 7.5%) and patients without glycemic control (HbA1c&gt; 7.5%).The prevalence of periodontal disease for patients diagnosed with T2DM was higher in uncontrolled patients who were classified within high Community Periodontal Index (CPI) codes between 3 (71.4%) and 4 (28.6%)5(Table 1).Similarly, it was observed that in the group of patients without glycemic control presented averages of Simplified Oral Hygiene Index (OHI‐S) cataloged between fair (57.1%) and poor (42.9%) (Table 2).DiscussionSimilar results were obtained by Janket (2005)6and Carneiro (2015)7, who relate a higher rate of periodontal disease in patients with higher HbA1c values.ConclusionIt was determined a relationship between glycemic control and periodontal disease in children, because patients with poor glycemic control (HbA1c&gt; 7.5%) presented CPI with degrees of inflammation and presence of periodontal pockets and poor OHI‐S.References Islas S, Revilla MC.

Effect of Dental Anxiety on Oral Health among the First-Time Dental Visitors: A Hospital-based Study.

Objective:The objective was to assess dental anxiety and to find its association with oral health status and oral health-related quality of life (OHRQoL) among 20–40-year-old patients visiting Vokkaligara Sangha Dental College and Hospital.Materials and Methods:A single-center, hospital-based cross-sectional study was done among first-time dental visitors in the Department of Oral Medicine and Radiology, Vokkaligara Sangha Dental College and Hospital over a period of 8 months (July 14–February 18). The sample size was determined to be 700. Participants in the age group of 20–40 years were selected based on inclusion and exclusion criteria. Data were collected using Corah's Modified Dental Anxiety Scale, Oral Health Impact Profile-14 (OHIP-14), and clinical examination was done using the WHO oral health assessment form and OHI-S. Data were analyzed using Chi-square test and t-test. The associations found through bivariate analysis were entered as predictor variables into linear and binomial logistic regression models with high dental anxiety as the outcome variable.Results:The results of the study suggested that 56% of the study participants were having dental anxiety. Local anesthetic injection (80%) and fear of tooth drilling (60%) were the most anxiety-provoking stimulus. Analysis of OHIP-14 suggested that respondents perceiving oral health as affecting their life quality (very often/fairly often) in the past year were observed for items such as tension, difficulty to relax, irritability, difficulty in doing usual jobs, and totally unable to function because of oral problems. Dental anxiety was significantly associated with gender (odds ratio [OR] = 1.32), education (OR = 1.43), occupation (OR = 2.07), poor oral hygiene status (OR = 3.15), presence of dental caries (OR = 2.67), bleeding on probing (OR = 1.57), presence of periodontal pockets (OR = 2.64), clinical attachment loss (OR = 1.63), and OHRQoL (OR = 1.76). Stepwise linear regression model of independent variables (<0.05 variables included) explained dental caries as highest predictor (39%), followed by debris (22%), calculus (38%), mean OHIS (27%), mean OHIP-14 (29%), deep pocket (14%), and the least predictor was shallow pocket (9%).Conclusion:Dental anxiety was associated with poor oral health status seeking further attention to modify patients' behavior regarding improvement in oral health status.

Non-carious cervical lesions (NCCLs) and associated factors: A multilevel analysis in a cohort study in southern Brazil.

To investigate the prevalence of non-carious cervical lesions (NCCLs) and their association with individual and tooth-related factors in adults from the 1982 Pelotas Birth Cohort. Participants were interviewed and clinically examined at the age of 31. NCCL was defined as loss of dental tissue without bacterial involvement in the cervical region. Independent variables were the socioeconomic, demographic, behavioural, and clinical characteristics. Associations were tested using a multilevel Poisson regression model. Five-hundred and thirty-nine participants were clinically examined, with a 26% prevalence of NCCLs, which were more prevalent in the maxilla (56.5%) and in premolars (72.9%). In the multilevel analysis, women presented lower prevalence than men [prevalence ratio (PR) 0.59 (0.48-0.73)]; those who reported smoking at both 22 and 30 years of age had more NCCLs than those who never smoked [PR 1.65 (1.31-2.07)]; and high-frequency brushers presented higher prevalence than low-frequency brushers [PR 1.26 (1.03-1.55)]. Gingival recession increased 10 times the prevalence of NCCLs [PR 10.03 (8.15-12.35)], while the presence of periodontal pockets (≥4 mm) reduced the prevalence of NCCLs [PR 0.43 (0.28-0.66)]. NCCLs were more prevalent in males, smokers, and those with higher frequency of toothbrushing. While the presence of periodontal pockets was associated with a lower prevalence of NCCLs, gingival recession was a strong clinical indicator for the presence of NCCLs.

Oral disease burden amongst residents of an internally displaced persons camp in Nigeria

&#x0D; &#x0D; &#x0D; &#x0D; Objective: To assess the prevalence of oral diseases and conditions amongst residents of an isolated camp that caters for internally displaced persons to define their oral health need in order to facilitate surveillance and planning of interventional programmes.&#x0D; Methods: A cross-sectional study carried out among randomly selected residents of a camp at Uhogua village forest reserve, Edo State, Nigeria. Socio-demographic data was obtained using an interviewer-administered questionnaire. Oral examination was carried out under natural illumination using mouth mirror, wooden spatula and blunt dental explorer. Oral hygiene was graded using Simplified Oral Hygiene Index. Diagnoses of caries and periodontal disease were according to the World Health Organization criteria. Clinical diagnosis of oral lesions/conditions was by visual inspection. IBM SPSS version 25.0 was used for descriptive and inferential analysis at 95% confidence interval with p set at &lt; 0.05 significance.&#x0D; Results: The mean age of the 437 study participants was 15.81 ± 8.42 with a range of 4 - 71 years. Males (43.0%), females (57.0%) and participants with primary education (78.7%). Only 3.4% of the study participants had good oral hygiene and 11.9% of the group had periodontal pockets. Dental caries prevalence was 19.7%. The DMFT/dmft index value was 0.33/0.13 with PUFA/pufa score of 0.06/0.02. However, 35.0% of permanent teeth and 79.0% of deciduous teeth had evidence of dento-oral infection and ulceration. The prevalence of oral ulcers (1.8%), leukoplakia (2.1%), erythroplakia (0.5%), oral candidiasis (5.3%), cleft palate (0.2%) and traumatic dental injury (4.3%). were noted. Lower educational attainment was associated with presence of periodontal pockets (p=0.029) and dental caries (p=0.004).&#x0D; Conclusion: Poor oral hygiene was prevalent in this group. Although the prevalence of oral diseases and conditions were low in comparison with previous local studies, many of the carious lesions had signs of dento-oral infections. Improved access to education with a significant oral health education content and preventive oral health services are recommended strategies in reducing the oral health challenges of this group.&#x0D; &#x0D; &#x0D; &#x0D;

Impact of dental health intervention on cardiovascular metabolic risk: a pilot study of Japanese adults.

This study aimed to determine whether a dental health education program would reduce cardiometabolic risk (obesity, hypertension, dyslipidemia, and hyperglycemia) in people with periodontitis. We used annual check-up data provided by the Japanese company's health insurance union. Of 182 male employees with cardiometabolic risk and periodontal pockets at baseline, 21 participants of the dental health education program and 21 non-participants matched for age, the presence of obesity, and periodontal pocket at baseline were allocated to the intervention (mean age, 53.3 ± 7.0) and the non-intervention groups (mean age, 52.9 ± 7.0), respectively. The program focused on self-removal of dental plaque with a toothbrush and interdental brush and comprised five sessions over 12 months. In the intervention group, waist circumference (cm) and diastolic blood pressure (mmHg) decreased from 88.4 ± 6.3 to 86.8 ± 6.3 and from 85.7 ± 8.2 to 82.6 ± 8.3, respectively (P < 0.05). Intergroup comparison showed significant improvement of systolic blood pressure (mmHg) in the intervention group (-3.7 ± 12.5) compared with the non-intervention group (4.0 ± 15.9) (P < 0.05) with no significant differences in the other parameters. The intervention group had a decrease in plaque accumulation and periodontitis symptoms, such as the depth of periodontal pocket and the presence of periodontal pocket and bleeding on probing, but an increase in the frequency of interdental brushing and duration of tooth brushing. Our findings show that dental self-care may improve blood pressure in people with cardiometabolic risk factors and periodontitis.

Oral Health Status and its Impact on Daily Performance in Adult Population with Diabetes

Background: According to World Health Organization (WHO), diabetes mellitus, is a silent epidemic which affects large number of people around the world and is directly related to the oral health status of the patients.&#x0D; Objectives: To know the level of oral health and its impact on daily performance in adult population with Diabetes.&#x0D; Methods: A cross sectional study was comprised of group of 100 diabetic patients (males=68, females=32) from the OPD of Dhaka Dental College and Shaheed Suhrawardy Medical college, Dental unit of Dhaka. Oral health status is assessed by WHO described DMFT caries index and CPITN (community periodontal index treatment need). And oral impact on daily performance is determined by a modified form of OIDP index. Clinical examinations were included for the assessment of Dental Status. Chi-square was used for statistical evaluation.&#x0D; Results: Mean DMFT of the study population of Decayed, Missing and filled tooth were 3.89±3.35, 3.04±2.66 and 3.87±2.66 However, in case of CPITN index of the study population, Supragingival or subgingival pocket more than 6mm was in 32% cases. Mean scores of overall impacts on daily performances (OIDP) was 2.18±1.85. Bivariate analysis revealed that the self-reported oral impacts from the participants were not significantly associated (p≥0.05) with those who were diagnosed with presence of periodontal pockets more than 6 mm (32%).&#x0D; Conclusions: Oral health is an essential part of general health. Despite dental caries was comparatively low in diabetics, periodontal status was compromised which affected the participant’s daily life chiefly through difficulty in eating. Routinely follow-up of dental problems of the diabetics and oral health education is much required.&#x0D; Update Dent. Coll. j: 2021; 11 (1): 7-10

Alcohol use and the development of periodontal pockets: An 11-year follow-up study.

This study investigates whether alcohol use predicts the periodontal pocket development over an 11-year follow-up period. The study participants' periodontal condition was examined both in the Health 2000 and 2011 Surveys (BRIF8901). Participants were aged 30 to 65 years, dentate, periodontally healthy, and did not have diabetes or rheumatoid arthritis in 2000. Periodontal outcome measures in 2011 were the number of teeth with deepened (≥4mm) periodontal pockets and the presence of deepened periodontal pockets. The exposure in 2000 was alcohol use (amount [g/week], frequency [any alcohol or different beverages]). Incidence rate ratios (IRRs) with 95% confidence intervals (CI) were estimated using negative binomial regression model and Poisson regression model with a robust variance estimator. Overall, the amount of alcohol use or use over the risk limit in 2000 was inconsistently associated with the development of periodontal pockets (IRRs varied from 0.6 to 1.0). The frequency of alcohol use (any alcohol or different beverages) had an inconsistent association with the presence of periodontal pockets (IRRs varied from 0.5 to 1.2) while there was an inverse association with the number of teeth with periodontal pockets. Among smokers, there were no clear associations between any of the exposures and either of the outcomes. The same was found among non-smokers except an inverse association was found between frequency of alcohol use and the number of teeth with periodontal pockets. Alcohol use was not consistently associated with the periodontal pocket development over a period of 11 years.

Dental caries experience and associated factors in 12-year-old-children: a population based-study.

Relevant public policies in oral health have been implemented in Brazil since 2004. Changes in the epidemiological status of dental caries are expected, mainly in the child population. This study aimed to assess the dental caries experience and associated factors among 12-year-old children in the state of São Paulo, Brazil. A cross-sectional population-based study was conducted with data obtained from 415 cities, including a total of 26,325 schoolchildren who were included by the double-stage cluster technique, by lot and by systematic sampling. The statistical model included data from the São Paulo Oral Health Survey (SBSP 2015), the Human Development Index (HDI) and the Social Vulnerability Index (SVI). A theoretical-conceptual model categorized the variables into three blocks, namely, contextual (HDI, SVI, region of residence and fluoridation of water), individual (sex and ethnicity) and periodontal conditions (gingival bleeding, dental calculus and the presence of periodontal pockets), for association with the experience of caries (DMFT). Statistically significant associations were verified by hierarchical multivariate logistic (L) and Poisson (P) regression analyses (p < 0.05). The results showed that 57.7% of 12-year-old children had caries experience. Factors that determined a greater prevalence of dental caries in both models were nonwhite ethnicity (ORL = 1.113, ORP = 1.154) and the presence of gingival bleeding (ORL = 1.204, ORP = 1.255). Male children (ORL = 0.920 ORP = 0.859) and higher HDI (ORL = 0.022), ORP = 0.040) were associated with a lower prevalence of dental caries experience. Water fluoridation was associated with a lower DMFT index (ORP = 0.766). Dental caries experience is still associated with social inequalities at different levels. Policymakers should direct interventions towards reducing inequalities and the prevalence of dental caries among 12-year-old children.

Effect of Periodontitis and Toothbrushing Frequency on Obesity Onset: A Cohort Study.

BackgroundThe interplay between obesity and periodontitis has been widely examined. While obesity was reported as a risk factor for periodontitis, the inverse relationship is still little explored. Therefore, we aimed to determine whether periodontitis and toothbrushing frequency affect the onset of obesity.Material/MethodsThis cohort study included 1619 employees of a business enterprise headquartered in Tokyo, who in 2002 and 2006 underwent in prescribed annual health checks, both general and dental-specific, and who were not obese in 2002 (body mass index <25). The response variable was obesity (or absence) at 4 years, while the explanatory variables were presence/absence of periodontal pockets and toothbrushing frequency in 2002; their relationships were examined by multiple logistic regression analysis.ResultsSubjects with periodontal pockets ≥4 mm showed a significantly higher odds ratio (OR) for onset of obesity at 4 years than those without periodontal pockets [OR: 1.59, 95% CI (confidence interval): 1.08–2.35, p<0.05]. Similarly, subjects who brushed their teeth ≥3 times/day had a significantly lower obesity OR than those who brushed ≤1 time/day (OR: 0.49, 95% CI: 0.28–0.85, p<0.01).ConclusionsThe presence of periodontal pockets and toothbrushing frequency are significantly associated with the onset of obesity. Periodontal pockets ≥4 mm are associated with increased risk of obesity, while frequent toothbrushing (≥3 times/day) appears to reduce the risk of obesity.

Odontogenic infections and leprosy reactions: A case–control study

Objective: To analyze the association between reactional episodes in leprosy and clinical and radiographic parameters relating to dental and gingival-periodontal structures of oral health. Methods: Observational case-control study unpaired with multibacillary leprosy patients evaluated between August 2012 and January 2014 from three endemic Brazilian municipalities; patients with first leprosy reaction (cases) were compared to patients without leprosy reaction (controls). The independent variables were grouped into: sociodemographic, disease clinical characteristics, behavior and lifestyle and dental and gingival-periodontal conditions. Two dentists were assigned to the fieldwork and the Kappa statistic was calculated. Logistic regression with 95% confidence interval was carried out. Results: The study included 57 individuals, including 23 reaction cases (40.4%) and 34 controls (59.6%). Chronic periodontal disease (CPD) (ORaj = 4.3; p = 0.033); the necessity for tooth extraction (ORaj = 23.4; p = 0.006), the presence of bone loss (ORaj = 6.5; p = 0.030), the presence of periodontal pockets (ORaj = 3.4; p = 0.045) and a visit to the dentist (ORaj =0.3; p = 0.014) are associated with reactional episodes in leprosy. Conclusions: The dental and gingival-periodontal parameters shown to be associated with reactional episodes in leprosy were the presence of teeth that need to be extracted, CPD, and the presence of a periodontal pocket. Alveolar bone reabsorption was a radiographic parameter associated with reactional episodes in leprosy.

Association between periodontal status and non-alcoholic fatty liver disease in a Korean adult population: A nationwide cross-sectional study.

The objective of this study was to investigate the association between periodontal status and non-alcoholic fatty liver disease (NAFLD) indicators in a representative Korean population. A cross-sectional study was conducted on 4061 participants>19 years of age using the 2010 Korea National Health and Nutrition Examination Survey data. Periodontal status was assessed by trained dentists using the community periodontal index. To identify the presence of NAFLD, biochemical data were defined using two validated indicators: the fatty liver index (FLI) and the hepatic steatosis index (HSI). The associations of the presence of periodontal pockets with FLI and HSI were evaluated by multivariable logistic regression analysis after adjusting for age, income, education level, smoking status, alcohol consumption, physical activity, diabetes mellitus, obesity, hypertension, and hypercholesterolemia. The adjusted means in the FLI indicator increased in the presence of periodontal pockets, whereas there was no significant difference in the HSI (P=0.005 for FLI; P =0.142 for HSI). Periodontal pockets were consistently associated with the two NAFLD indicators in the sequential logistic models for women throughout the adjustment process. (OR=1.77, 95% CI=1.05 to 2.98 for FLI, OR=1.64, 95% CI=1.08 to 2.51 for HSI). Our findings showed that the presence of periodontal pockets may be independently associated with NAFLD indicators. Further study will be clarified by well-designed longitudinal studies.

Alcohol use and periodontal pocket development: findings from a 4-yr longitudinal study.

This study investigated whether alcohol use influences periodontal pocket development during a 4-yr follow-up period. The study included those participants who took part in both the Health 2000 Survey and the Follow-up Study on Finnish Adults' Oral Health. The participants at baseline were aged ≥30yr, periodontally healthy, and did not have diabetes or rheumatoid arthritis. The development of periodontal pockets at follow-up was measured as the number of teeth with periodontal pockets and the presence of periodontal pockets. Alcohol use at baseline was measured as g/wk, frequency, and use over the risk limit. Incidence rate ratios with 95% CI were estimated using negative binomial regression models and Poisson regression models with a robust variance estimator.No consistent association was found between any of the alcohol variables andperiodontal pocket development in the total population or among non-smokers. Among smokers, a positive association was found with the frequency of alcohol use. In general, risk estimates were slightly higher for women than for men. In summary, light-to-moderate alcohol use appears not to be consistently associated with the development of periodontal pockets. The adverse effects on the periodontium seem, to some extent, to be dependent on gender and smoking.
