Poor Oral Health Predicts Higher 10-Year Cardiovascular Risk: A Propensity Score Matching Analysis

Background: Although the association between periodontitis and cardiovascular disease (CVD) has been reported, whether periodontitis and poor oral health behavior influence CVD risk remains unclear.

Objective: The aim of this study was to examine whether periodontal disease and poor oral health behavior predict 10-year general CVD risk using the Framingham Risk Score.
Methods: Patients older than 30 years with no CVD history (n = 8370) were selected using cross-sectional study data from the Korean National Health and Nutrition Examination Survey in 2013 and 2014. To reduce selection bias in this population-based study, propensity score matching analysis was used with SPSS and R programs to compare CVD risk.

Results: Overall, 39.2% of the study population (n = 3277) had a global CVD risk of 10% or greater. In the low- and at-risk groups, 20.7% and 45.3% of patients, respectively, were diagnosed with periodontal disease by a dentist. Moreover, 43.2% and 62.8% of the low- and at-risk group patients, respectively, brushed teeth less than 3 times a day. After 1:1 propensity score matching of the low-risk (n = 1135) and at-risk (n = 1135) groups, bivariate analyses showed that a diagnosis of periodontal disease and less frequent toothbrushing were associated with a higher CVD risk (P < .001). Logistic regression analysis also showed that patients having periodontal disease and who brushed teeth less frequently were 1.38 and 1.33 times, respectively, more likely to be at risk of CVD (P < .001).

Conclusion: Education on periodontitis management and oral hygiene behavior should be included, when strategies for public risk reduction of CVD are developed.

Evaluation of occlusal caries detection and assessment by visual inspection, digital bitewing radiography and near-infrared light transillumination

Abstract

Aim

This study compared the diagnostic outcomes of visual inspection (VI), digital bitewing radiography (BWR), and near-infrared light transillumination (NIR-LT, DIAGNOcam, KaVo, Biberach, Germany) for occlusal caries detection and assessment of posterior teeth.

Participants and methods

This study included 203 patients (mean age 23.0 years). All individuals received a meticulous VI. Additionally, BWR and NIR-LT images were collected. All BWR and NIR-LT images were blindly evaluated for the presence of enamel caries lesions (ECLs) and dentin caries lesions (DCLs). The descriptive statistical analyses included calculation of frequencies, cross tabulations, and pairwise comparisons using Pearson chi-square tests.

Results

The majority of ECLs/DCLs were detected by VI in this low-risk adult population. The additional diagnostic outcomes in terms of ECLs/DCLs amounted to 5.0% (BWR) and 6.8% (NIR-LT). The combined usage of VI/NIR-LT or VI/BWR identified 95.7 and 94.4% of all ECLs/DCLs on occlusal surfaces, respectively.

Conclusion

This comparative diagnostic study showed that VI detected the majority of occlusal caries lesions. Both additional methods showed limited benefits. Due to the valuable features of NIR-LT, i.e., X-ray freeness and clinical practicability, this method might be preferred over X-ray-based methods. Nevertheless, BWRs should be prescribed in clinical situations where insufficient fillings or multiple (deep) caries lesions are diagnosed or where there is a need to assess the caries extension in relation to the pulp.

Clinical relevance

VI has to be understood as caries detection method of choice on occlusal surfaces in low-risk adult population which may help to avoid multiple diagnostic testing, overdiagnosis, and overtreatment.

Dental care may benefit patients scheduled for cancer surgery

Preoperative oral care by a dentist may help reduce postoperative complications in patients who undergo cancer surgery, according to a new BJS (British Journal of Surgery) study.

Of 509,179 patients studied, 16% received preoperative oral care from a dentist. When a surgeon requested that a dentist provide preoperative oral care to a patient with cancer, the dentist checked the patient’s oral condition, provided professional tooth cleaning, taught the patient self-cleaning methods for the teeth, and provided any treatment needed.
In the study, 15,724 patients (3.09%) developed postoperative pneumonia and 1734 (0.34%) died within 30 days of surgery. After adjustments, preoperative oral care by a dentist was linked with a decrease in postoperative pneumonia (3.28% versus 3.76%) and death within 30 days (0.30% versus 0.42%).
"The findings could help improve strategies for the prevention of postoperative complications," the authors wrote.

Comparison of immediate‐load mini dental implants and conventional‐size dental implants to retain mandibular Kennedy class I removable partial dentures: A randomized clinical trial

First published: 31 July 2018

 

Abstract

Background

Complications of distal extension mandibular removable partial dentures are: loss of retention, irritation, and so forth. Dental implants have been used to support distal extension removable partial dentures. However, many patients have limited bone support in which to place conventional‐size dental implants.

Purpose

To compare the clinical outcomes of using immediate‐loaded mini dental implants and immediate‐loaded conventional‐size dental implants, when used to retain mandibular Kennedy class I removable partial dentures.

Materials and Methods

Thirty patients were randomly divided into two groups. Mini dental implants and conventional‐size dental implants were placed in participants in the first molar region on both sides. The dentures were connected immediately. Patients were recalled on 1, 3, 6, and 12 months after surgery. Digital periapical radiographs were made, and patient satisfaction was recorded. Data were analyzed by independent samples t‐test and paired samples t‐test (P = .05).

Results

Twenty eight of the implants survived (survival rate = 93.3%) in each group. Mean radiographic bone loss was 0.47 ± 0.42 and 1.03 ± 1.07 mm in groups 1 and 2, respectively. Conventional‐size implants revealed significantly greater marginal bone loss than mini implants (P = .01). Patient satisfaction showed significant improvement after treatment in both groups.

Conclusions

Immediate‐loaded mini dental implants can be applied for retaining mandibular Kennedy class I removable partial dentures with very favorable results.
