At Ly Thuong Kiet primary school in Hanoi, in 42 school children aged from 8-11 years old, an odonto-stomatology investigation was performed. Results showed that: tooth caries were usually detected in almost subjects with an equal incidence in boys and girls. Milk teeth caries had got high incidence in an average of 2.6 caries for each subject. This incidence was lower for permanent teeth – average 0.5 for each. The results found an significant improvement of odonto-stomatological health in comparing with the last second investigation at national level.

ABSTRACT This hospital-based cross-sectional study aimed at determining frequency and risk indicators/predictors of periodontitis in a sample of Egyptian adult population and to develop a prediction equation for classifying periodontal diseases. Seven hundred and fifty subjects were consecutively recruited from outpatient Diagnostic Center, Faculty of Dentistry, Cairo University. Validated oral health questionnaire for adults and oral health impact profile-14 (OHIP-14) questionnaire were filled by all patients. Diagnosis was made based on measurements of clinical periodontal parameters including plaque index, bleeding on probing, pocket depth, clinical attachment level and gingival recession. Radiographic examination was performed using digital periapical radiographs. Ordinal logistic regression analysis was used to determine significant predictors of periodontal diseases and discriminant analysis was performed to predict periodontal disease classification. Gingivitis was the most frequent periodontal disease (39.6%) followed by periodontitis stage I (38%), stage II (20.4%), stage III (1.6%) and stage IV (0.4%). The lowest OHIP-14 scores were in patients with periodontitis stages III and IV. Multivariate analysis showed that education (p < 0.001), OHIP-14 score (p = 0.003), non-smoking (p = 0.001) and non-alcohol drinking (p = 0.021) were significant negative predictors, while never to clean the teeth (p <0.001) and cleaning the teeth once a month (p < 0.001) were significant positive predictors of periodontal disease. Periodontitis stages III and IV were the least frequent on a sample of Egyptian adult patients. Education, frequency of teeth cleaning, smoking, alcohol drinking and OHIP-14 scores were significant predictors of periodontal disease. Through discriminant analysis this study could classify patients into different periodontal diseases with an overall correct prediction of 99.2%.

OBJECTIVETo evaluate the accuracy of partial- mouth periodontal examination (PMPE) protocols frequently used in epidemiological periodontal surveys.

METHODSArticles in English or Chinese published before Jan 31st 2014 were searched, which compared the results of PMPE protocols with those of gold-standard protocol, i.e.full-mouthmesialbuccal-midbuccal-distobuccal-mesiolingual-midlingual-distolingual (MB-B-DB-ML-L-DL) protocol.

RESULTSTwelve articles were included and nine that frequently used PMPE protocols were evaluated. All these protocols underestimated the prevalence scores. For prevalence of probing depth (PD) ≥ 4 mm, 6 mm and attachment loss (AL) ≥ 4 mm, 6 mm, smaller amount of underestimation was observed in community periodontal index of treatment needs (CPITN) teeth (-12.6%--3.5%), full-mouth MB-B-DB (-16.1%--3.5%), full-mouth MB-B-DL (-10.8%--6.1%) and half-mouth MB-B-DB-ML-L-DL (-23.6%--2.0%) protocols. For severity and extent estimates, half-mouth MB-B-DB-ML- L-DL provided lowest biased results (relative bias: -1.0%- 1.1% for severity and -6.7%-0.1% for extent). Full-and half-mouth MB-B-DB also performed well, with relative bias within ± 5.0% in most cases. CPITN overestimated the severity and extent of periodontal disease, the relative bias of which amounted to 42.3% and 38.1%, respectively.

CONCLUSIONSHalf-mouth MB-B-DB-ML-L-DL and full-mouth MB-B-DB protocols caused lower biased results in prevalence, severity and extent estimates of PD and AL.

To analyze the global burden of periodontal disease and its relation with socioeconomic development. Data of global disability-adjusted life year (DALY) due to periodontal disease and human development index (HDI) from 1990 to 2019 were obtained from Global Health Data Exchange (GHDx) and human development reports. The trend of the global burden of periodontal disease from 1990 to 2019 was described. The correlation between age-standardized DALY rates and HDI were examined in 2019, and between-country periodontal disease burden inequality from 1990 to 2019 was measured using health-related Gini coefficients and concentration indexes. From 1990 to 2019, the global DALY rate due to periodontal disease increased from 78.63 to 85.48, and the epidemiological burden did not increase significantly. Statistical differences were found across different HDI categories for age-standardized DALY rates of periodontal disease ( 44.315, <0.01) in 2019. Linear regression analysis also revealed a negative correlation between age-standardized DALY rate of periodontal disease and HDI ( = -0.417, <0.01) . Gini coefficients decreased from 0.361 to 0.281 and concentration indexes fell from 0.0339 to -0.0538 between 1990 and 2019. The global burden of periodontal disease did not increase between 1990 and 2019, though the socioeconomic-associated inequality still existed. The burden of periodontal disease was more concentrated in less developed countries, and the socioeconomic-associated inequality has increased since 2000.

OBJECTIVETo investigate the possible association between mother's periodontal status and preterm low birth weight (PLBW) in Beijing.

METHODSThe periodontal status of 83 women who bore a preterm low birth weight infant (PLBW group) and 44 women who bore a normal birth weight infant (NBW group) within two years in four hospitals in Beijing were evaluated. These women were all generally healthy. The clinical periodontal parameters including plaque index (PLI), probing depth (PD), attachment loss (AL) and bleeding index (BI) recorded.

RESULTSThe percentages of PD > or = 4 mm sites, AL > or = 2 mm sites and BOP(+) sites in two groups were 8.1% vs 6.9%, 12.8% vs 6.1% and 70.4% vs 66.9%, respectively, which showed significantly higher in PLBW group than in NBW group(P < 0.01, P < 0.001, P < 0.01).

CONCLUSIONSThere was possible association between mother's periodontal status and preterm low birth weight in the investigated area. Poor periodontal status may be one of the risk factors of PLBW.

INTRODUCTION: Chronic periodontal disease is a highly prevalent dental condition affecting tooth-supporting tissues. Scientific evidence is accumulating on links between periodontal disease and various systemic conditions. This narrative review provides a holistic yet succinct overview that would assist medical practitioners to deliver integrated care for better clinical outcomes. METHOD: Scientific evidence on associations between periodontal disease and systemic conditions was synthesised and critically appraised. Key findings of latest prospective cohort studies, randomised clinical trials, and meta-analysis were closely assessed and compiled. RESULTS: A bidirectional relationship has been established, indicating that diabetes and periodontal disease are closely linked and amplify one another, if not successfully controlled. Existing evidence also supports the associations of periodontal disease with cardiovascular diseases and adverse pregnancy outcomes. Successful treatment of periodontal disease and dental prophylaxis has been shown to improve clinical outcomes in these systemic conditions. Other systemic conditions associated with periodontal disease include respiratory diseases, Alzheimer's disease, rheumatoid arthritis and chronic kidney disease. Although the underlying mechanisms remain to be fully elucidated, it is generally accepted that the inflammatory burden of chronic periodontal disease has an important systemic impact. CONCLUSION Oral-systemic links are multifaceted and complex. While evidence linking periodontal disease with a variety of systemic conditions is still emerging, the nature of the relationship is becoming clearer. The updated understanding of these associations warrants the attention of medical experts and policymakers for a concerted effort to develop a patient-centric, integrated model for the treatment of comorbid dental and medical conditions.

PURPOSE: The aim of this study is to analyze and visualize the distribution of patients visiting the periodontology department at a dental college hospital, using a geographic information system (GIS) to utilize these data in patient care and treatment planning, which may help to assess the risk and prevent periodontal diseases. METHODS: Basic patient information data were obtained from Dankook University Dental Hospital, including the unit number, gender, date of birth, and address, down to the dong (neighborhood) administrative district unit, of 306,656 patients who visited the hospital between 2007 and 2014. The data of only 26,457 patients who visited the periodontology department were included in this analysis. The patient distribution was visualized using GIS. Statistical analyses including multiple regression, logistic regression, and geographically weighted regression were performed using SAS 9.3 and ArcGIS 10.1. Five factors, namely proximity, accessibility, age, gender, and socioeconomic status, were investigated as the explanatory variables of the patient distribution. RESULTS: The visualized patient data showed a nationwide scale of the patient distribution. The mean distance from each patient's regional center to the hospital was 30.94±29.62 km and was inversely proportional to the number of patients from the respective regions. The distance from a regional center to the adjacent toll gate had various effects depending on the local distance from the hospital. The average age of the patients was 52.41±12.97 years. Further, a majority of regions showed a male dominance. Personal income had inconsistent results between analyses. CONCLUSIONS: The distribution of patients is significantly affected by the proximity, accessibility, age, gender and socioeconomic status of patients, and the patients visiting the periodontology department travelled farther distances than those visiting the other departments. The underlying reason for this needs to be analyzed further.
