To elucidate the association between the intake of soft drinks and periodontal disease (PD) among Taiwanese middle-aged adults.The cross-sectional design was employed to assess a dose-response relationship between the intake of soft drinks and PD after controlling for relevant confounding factors, with adjusted odds ratios obtained from a multivariate logistic regression model.Keelung Community-based Integrated Screening (KCIS) programme, Keelung, Taiwan.Participants (n 10 213) aged 35-44 years who had undergone oral checks for PD between 2005 and 2009.A dose-response relationship between the intake of soft drinks and elevated risk for PD defined by community periodontal index ≥3 (the current status of PD) was noted (P=0·02 by trend test). Compared with infrequent intake of soft drinks (≤2 times/week), the adjusted OR increased from 1·05 (95 % CI 0·92, 1·20) for the frequency of 3-4 times/week to 1·17 (95 % CI 1·03, 1·34) for the frequency of ≥5 times/week. A similar trend (P<0·01) was also observed for PD defined by loss of attachment ≥1 (representing the long-term cumulative gum damage due to PD).A dose-response relationship between the intake frequency of soft drinks and PD was observed in Taiwanese middle-aged adults. Such evidence could be used in health promotion to support reductions in soft drink intake.

Receiver Operating Characteristic Curve–Based Prediction Model for Periodontal Disease Updated With the Calibrated Community Periodontal Index

Journal of Periodontology (2017)

Chiu‐Wen Su Amy Ming‐Fang Yen Hongmin Lai Chien‐Jen Chen Sam Li‐Sheng Chen

Background: The accuracy of a prediction model for periodontal disease using the community periodontal index (CPI) has been undertaken by using an area under a receiver operating characteristics (AUROC) curve. How the uncalibrated CPI, as measured by general dentists trained by periodontists in a large epidemiologic study, and affects the performance in a prediction model, has not been researched yet. Methods: A two‐stage design was conducted by first proposing a validation study to calibrate CPI between a senior periodontal specialist and trained general dentists who measured CPIs in the main study of a nationwide survey. A Bayesian hierarchical logistic regression model was applied to estimate the non‐updated and updated clinical weights used for building up risk scores. How the calibrated CPI affected performance of the updated prediction model was quantified by comparing AUROC curves between the original and updated models. Results: Estimates regarding calibration of CPI obtained from the validation study were 66% and 85% for sensitivity and specificity, respectively. After updating, clinical weights of each predictor were inflated, and the risk score for the highest risk category was elevated from 434 to 630. Such an update improved the AUROC performance of the two corresponding prediction models from 62.6% (95% confidence interval [CI]: 61.7% to 63.6%) for the non‐updated model to 68.9% (95% CI: 68.0% to 69.6%) for the updated one, reaching a statistically significant difference ( P <0.05). Conclusion: An improvement in the updated prediction model was demonstrated for periodontal disease as measured by the calibrated CPI derived from a large epidemiologic survey.

Long‐term effectiveness of school‐based children oral hygiene program on oral health after 10‐year follow‐up

Community Dentistry And Oral Epidemiology (2015)

Hongmin Lai Jean Ching‐Yuan Fann Amy Ming‐Fang Yen Sam Li‐Sheng Chen Min‐Hua Lai

The aim of this study was to evaluate the long-term effectiveness of a school-based child oral hygiene program on oral heath after approximately 10 years of follow-up.A prospective cohort study was designed to include 120 schoolchildren aged 10-11 years with instructions on how to practice daily flossing and brushing under the supervision of school nurses for one semester (the intervention group) and to recruit a comparison group with no intervention from 120 classmates matched by gender (the nonintervention group). Both groups participated in a questionnaire survey and received dental examinations after long-term follow-up.The mean value of overall plaque score in the intervention group (16.9%) was lower than that of the nonintervention group (32.6%); the adjusted relative risk (aRR) of having a plaque score for the intervention group versus the nonintervention group was 0.4 (95% CI: 0.3, 0.5). The percentage of pocketing (CPI ≧ 2) in the intervention group (75.0%) was lower than that of the nonintervention group (90.8%); the aRR of having calculus or pocketing (CPI ≧ 2) was 0.3 (95% CI: 0.1, 0.6). The intervention group had lower DMFT values and DMFS score than the nonintervention group (4.1 and 6.6 versus 6.2 and 11.0). Moreover, the intervention group had significantly better dental knowledge and habits and dental conditions than the nonintervention group.This longitudinal follow-up study demonstrated that a highly targeted oral hygiene program can display positive long-term effectiveness.

A population‐based study on the association between type 2 diabetes and periodontal disease in 12,123 middle‐aged Taiwanese (KCIS No. 21)

Journal Of Clinical Periodontology (2009)

Tingting Wang Chien‐Jen Chen Po‐En Wang Hongmin Lai Ming‐Te Lo

We investigated the association between type 2 diabetes mellitus (T2DM) and periodontal disease (PD) in the context of the current periodontal aetiology model.In total, 14,747 community residents aged 35-44 years were invited to a community-based PD survey between 2003 and 2006 using the community periodontal index. Significant factors modifying the association between T2DM and PD were ascertained. We further assessed the association between T2DM and the risk for PD, within strata of significant effect modifiers, after controlling for other putative factors.The prevalence rate was 10% higher in subjects with T2DM than in those without. After controlling for significant factors, T2DM was positively associated with the risk for PD (adjusted odds ratio=1.34,95% confidence interval: 1.07-1.74). The results of interaction assessment showed that only the waist was identified as a statistically significant effect modifier for such a positive association.The association between T2DM and the risk for PD among young adult was demonstrated. This finding, together with other aetiological factors, fit with the current hypothesized model of the aetiology of periodontitis. However, the effect of T2DM modified by waist measurement should be verified in future studies.

Prevalence of Dental Caries and Periodontal Disease of High School Students Aged 15 to 18 Years in Taiwan

International Journal of Environmental Research and Public Health (2021)

Po-Sen Chang Chun-Jui Huang Chia‐Lan Hsiang Hongmin Lai Aileen I. Tsai

The purpose of this study was to assess the prevalence and distribution of dental caries and periodontal disease in Taiwanese high school students aged 15-18. A total of 1069 Taiwanese students participated in a cross-sectional nationwide dental survey. By using a stratified method based on the National Health Insurance administration regions, 24 high schools were randomly sampled in different areas of Taiwan. The participants were examined with dental mirrors and community periodontal index (CPI) probes without using radiographs, to measure dental caries and periodontal status. Demographic information and other relevant risk indicators for the two diseases were gathered via a self-report questionnaire. In this study population, the weighted mean decayed, missing and filled teeth (DMFT) scores for ages 15 to 18 were 5.2, 6.1, 6.1, and 5.7. The weighted mean decayed, missing and filled surfaces (DMFS) scores were 9.0, 12.0, 13.1, and 11.2 at ages 15, 16, 17, and 18, respectively. Additionally, 88.2% of the subjects had periodontal disease, with calculus as the most prevalent type. Moreover, 5.2% of these students showed loss of attachment. There was no significant association between dental caries and periodontal disease. Dental caries and periodontal disease were prevalent among Taiwanese high school students in this national dental survey.

Association between patients' chief complaints and their compliance with periodontal therapy

Journal Of Clinical Periodontology (2011)

Hwey‐Chin Yeh Hongmin Lai

To evaluate the association between patients' chief complaints (CCs) and their compliance with basic periodontal therapy.Data on CCs and periodontal diseases were obtained from patients attending a periodontal clinic. Patient compliance with basic periodontal therapy was studied in relation to their CCs.The mean age of the 1196 subjects was 47.7±11.6 years. Among them, 36.9% of the subjects had chronic symptomatic CCs; 22.4%, acute symptomatic CCs; and 40.7%, asymptomatic CCs. Four hundred eighty subjects completed basic periodontal therapy; 209, incomplete treatment; and 507, no treatment. The subjects with acute symptomatic CCs were 60% more likely to receive periodontal treatment [odds ratio (OR)=1.661; 95% confidence interval (CI): 1.203-2.293] than chronic symptomatic subjects, as did the asymptomatic subjects (OR=1.669; 95% CI: 1.252-2.223). However, subjects with acute symptomatic CCs were 60% less likely to complete periodontal treatment (OR=0.420; 95% CI: 0.267-0.660). The OR of completing treatment for the copayment requirement was 1.944, while that for being treated by an experienced periodontist was 1.695.Patients' CCs were associated with their compliance to basic periodontal therapy. Acute symptomatic CCs may be a positive predictor to initiate periodontal treatment but a negative predictor to complete the treatment.
