Pocket depth and bleeding on probing and their associations with dental, lifestyle, socioeconomic and blood variables: a cross-sectional, multicenter feasibility study of the German National Cohort

Abstract

BackgroundTo investigate the periodontal disease status in a multi-center cross-sectional study in Germany. Associations of dental, socio-economic, blood and biomedical variables with periodontal outcome parameters were evaluated.MethodsFrom 4 different centers N = 311 persons were included, drawn randomly from the registration offices. Maximal pocket depth (PD) was used as primary indicator for periodontitis. It was classified as: no/mild ≤3 mm, moderate 4-5 mm, severe ≥6 mm. Associations between socioeconomic (household income, education), lifestyle, and biomedical factors and PD or bleeding on probing (BOP) per site (“Yes”/”No”) was analyzed with logistic regression analysis.ResultsMean age of subjects was 46.4 (range 20–77) years. A significantly higher risk of deeper pockets for smokers (OR = 2.4, current vs. never smoker) or persons with higher BMI (OR = 1.6, BMI increase by 5) was found. Severity of periodontitis was significantly associated with caries lesions (p = 0.01), bridges (p < .0001), crowns (p < .0001), leukocytes (p = 0.04), HbA1c (p < .0001) and MCV (p = 0.04). PD was positively correlated with BOP. No significant associations with BOP were found in regression analysis.ConclusionsEarlier findings for BMI and smoking with severity of PD were confirmed. Dental variables might be influenced by potential confounding factors e.g. dental hygiene. For blood parameters interactions with unknown systemic diseases may exist.

Zirconia Versus Metal Cad/Cam Extracoronal Attachments for the Bilateral Distal Extension Removable Partial Magnet Versus Ols Attachments for Implant Overdentures: A Stress Analysis Study

“…BOP and PD were significantly higher in both groups at the end of the follow-up period, although there was no significant difference between the two groups regarding both parameters. However, the mean pocket depth for each group was less than 3mm, which remains within the normal range for healthy periodontium 30 . This slight decline in periodontal condition is probably a normal consequence of the presence of fixed restoration on the abutment teeth.…”

Effect of dental caries and the consequential variation in blood parameters on the anaerobic performance of rowing athletes

“…A dental caries is a chronic bacterial infection; studies showed that hemoglobin, iron, and ferritin levels increased when dental caries was cured (27). Another study suggested that erythrocyte levels were not affected by poor oral health (31). The present study suggested that the erythrocyte, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, red cell distribution width, and iron and ferritin levels were similar in both the groups.…”

Methodological issues in assessing the association between periodontitis and caries among adolescents

“…Even though some evidence has been provided for antagonism between Aa and Sm , this has only been observed in vitro . While the findings of later studies did not support a negative relationship between juvenile periodontitis and caries, studies continue to purport a lower caries experience in “aggressive” periodontitis cases than in cases of “chronic” periodontitis …”
