Abstract Objectives The aim of this study was to develop a prognostic tool to estimate long-term tooth retention in periodontitis patients at the beginning of active periodontal therapy (APT). Material and methods Tooth-related factors (type, location, bone loss (BL), infrabony defects, furcation involvement (FI), abutment status), and patient-related factors (age, gender, smoking, diabetes, plaque control record) were investigated in patients who had completed APT 10 years before. Descriptive analysis was performed, and a generalized linear-mixed model-tree was used to identify predictors for the main outcome variable tooth loss. To evaluate goodness-of-fit, the area under the curve (AUC) was calculated using cross-validation. A bootstrap approach was used to robustly identify risk factors while avoiding overfitting. Results Only a small percentage of teeth was lost during 10 years of supportive periodontal therapy (SPT; 0.15/year/patient). The risk factors abutment function, diabetes, and the risk indicator BL, FI, and age (≤ 61 vs. > 61) were identified to predict tooth loss. The prediction model reached an AUC of 0.77. Conclusion This quantitative prognostic model supports data-driven decision-making while establishing a treatment plan in periodontitis patients. In light of this, the presented prognostic tool may be of supporting value. Clinical relevance In daily clinical practice, a quantitative prognostic tool may support dentists with data-based decision-making. However, it should be stressed that treatment planning is strongly associated with the patient’s wishes and adherence. The tool described here may support establishment of an individual treatment plan for periodontally compromised patients.

Abstract Background Clinical evidence indicates that there are various risk factors of tooth loss. However, the degree of this risk among other risk factors remains unclear. In this retrospective cohort study, the authors evaluated the hazard ratios of several risk factors for tooth loss. Methods Included patients had all been treated for dental disorders, were in the supportive phase of periodontal therapy by dental hygienists, and visited a Japanese dental office continually during a 10-year period. Periodontal parameters, tooth condition, and general status of all teeth (excluding third molars) at the initial visit and at least 10 years later were evaluated by using multiple classification analysis. Results The authors evaluated a total of 7584 teeth in 297 patients (average age: 45.3, mean follow-up time: 13.9 years) Non-vital pulp was the most significant predictor of tooth loss according to Cox hazards regression analysis (hazard ratio: 3.31). The 10-year survival rate was approximately 90% for teeth with non-vital pulp and 99% for teeth with vital pulp. Fracture was the most common reason for tooth loss. Conclusions Non-vital pulp had the most significant association with tooth loss among the parameters. Therefore, it is very important to minimize dental pulp extirpation.

Tooth loss represents a diffused pathologic condition affecting the worldwide population. Risk factors have been identified in both general features (smoking, diabetes, economic status) and local tooth-related factors (caries, periodontitis). In this retrospective study, we examined the data of 366 patients with a large number of remaining teeth (≥25) undergoing maintenance therapy in order to identify specific risk factors for tooth loss. The number of remaining teeth, number of non-vital teeth, and number of occlusal units were investigated for their correlation with tooth loss. The mean follow-up of patients was 9.2 years (range 5 to 14). Statistically significant risk factors for tooth loss were identified as number of remaining teeth at baseline (p = 0.05), number of occlusal units (p = 0.03), and number of non-vital teeth in posterior regions (p < 0.001). Multiple logistic regression showed that the number of occlusal units and number of non-vital teeth in the posterior regions were significantly associated with a greater risk of tooth loss (odds ratio 1.88 and 3.17, respectively). These results confirm that not only the number of remaining teeth, but also their vital or non-vital status and the distribution between the anterior and posterior regions influence the long-term survival.

Abstract Background Many studies have been conducted to investigate risk factors of falls in older people, but little is known about falls among centenarians. We analyzed the cross-sectional data from the Five-Country Oldest Old Project (5-COOP) to investigate the prevalence and correlates of falls among centenarians. Methods Data collection was carried out in 2011–2014 in Japan, France, Switzerland, Sweden, and Denmark. The sample consisted of 1,165 centenarians who were at least 100 years old in 2011. The outcome variable was falls in the past 6 months. Demographics, chronic conditions, pain, visual impairment, global cognitive function, dizziness and syncope, number of medications, functional limitation (ie, dressing, bathing, toileting, transferring, incontinence, and feeding), mobility difficulty, poor strength, and assistive device usage were included in the analysis. Results The prevalence of falls within the last 6 months was 33.7%, ranging from 21.6% (Japan) to 40.9% (France). Being male, experiencing dizziness, syncope, incontinence, and using assistive devices indoors were associated with an increased risk of falls among centenarians. Significant cross-country differences in the relationships between some risk factors (ie, gender, difficulty with bathing, toileting, transferring, and feeding, and using assistive devices for walking indoors and outdoors) and falls were observed. Subsample analysis using data from each country also showed that factors related to falls were different. Conclusions The prevalence of falls among centenarians is high and fall-related factors may be different than those for their younger counterparts. Given that centenarians is an emerging population, more studies investigating risk factors are needed to better understand falls among centenarians.

Objective: Males with peripheral arterial disease (PAD) are at high risk of ischaemic stroke given that atherogenic risk factors for both diseases are similar. We hypothesized that neurologically asymptomatic males diagnosed with PAD would demonstrate calcified carotid artery plaques (CCAP) on panoramic images (PI) significantly more often than similarly aged males not having PAD. Methods: Investigators implemented a retrospective cross-sectional study. Subjects were male patients over age 50 diagnosed with PAD by ankle-brachial systolic pressure index results of [Formula: see text]0.9. Controls negative for PAD had an ankle-brachial systolic pressure index > 0.9. Predictor variable was a diagnosis of PAD and outcome variable was presence of CCAP. Prevalence of CCAP amongst the PAD+ patients was compared to prevalence of CCAP among PAD- patients. Descriptive and bivariate statistics were computed and p-value was set at 0.05. Results: Final sample size consisted of 234 males (mean age 72.68 ± 9.09); 116 subjects and 118 controls. Among the PAD+ cohort, CCAP+ prevalence rate (57.76%) was significantly (p = 0.001) greater than the CCAP+ rate (36.44%) of the PAD- (control). There was no significant difference in atherogenic “risk factors” in the PAD+ cohort between CCAP+ and CCAP– subjects. Conclusion: We demonstrated that CCAP, a “risk factor” for future stroke and “risk indicator” of future myocardial infarction is seen significantly more often detected on the PIs of older male patients with PAD than among those without. Dentists treating patients with PAD must be uniquely vigilant for the presence of CCAPs on their patients’ PI.
