Osseointegration Foundation Charity Overdenture Program Study: Part 2.

This assessment evaluated the clinical feasibility of using narrow-diameter implants to support a mandibular overdenture. Twelve patients presenting with an edentulous mandible were recruited from nine dental offices. Each patient received two to four implants in the mandible. The implants were placed without additional bone augmentation, and a total of 36 implants were placed. All sites achieved satisfactory crestal bone stability and soft tissue maintenance 1 year after the final prosthetic restoration. This investigation was supported by the Osseointegration Foundation, working in conjunction with the Zest Anchors implant company. There are three basic valuable activities that emerge from a professional foundation, which were reflected in this case study. They include disseminating information to practitioners, persuading young clinicians to become research investigators, and reaching out to patients in need of treatment who cannot afford it without a charitable opportunity.

A model for predicting physical function upon discharge of hospitalized older adults in Taiwan-a machine learning approach based on both electronic health records and comprehensive geriatric assessment.

Background: Predicting physical function upon discharge among hospitalized older adults is important. This study has aimed to develop a prediction model of physical function upon discharge through use of a machine learning algorithm using electronic health records (EHRs) and comprehensive geriatrics assessments (CGAs) among hospitalized older adults in Taiwan. Methods: Data was retrieved from the clinical database of a tertiary medical center in central Taiwan. Older adults admitted to the acute geriatric unit during the period from January 2012 to December 2018 were included for analysis, while those with missing data were excluded. From data of the EHRs and CGAs, a total of 52 clinical features were input for model building. We used 3 different machine learning algorithms, XGBoost, random forest and logistic regression. Results: In total, 1,755 older adults were included in final analysis, with a mean age of 80.68 years. For linear models on physical function upon discharge, the accuracy of prediction was 87% for XGBoost, 85% for random forest, and 32% for logistic regression. For classification models on physical function upon discharge, the accuracy for random forest, logistic regression and XGBoost were 94, 92 and 92%, respectively. The auROC reached 98% for XGBoost and random forest, while logistic regression had an auROC of 97%. The top 3 features of importance were activity of daily living (ADL) at baseline, ADL during admission, and mini nutritional status (MNA) during admission. Conclusion: The results showed that physical function upon discharge among hospitalized older adults can be predicted accurately during admission through use of a machine learning model with data taken from EHRs and CGAs.

Nonpharmacological Behavior Guidance for Children with Special Health Care Needs During Preventive and Treatment Dental Visits: A Systematic Review-Part 3.

PURPOSE: To assess the effectiveness of nonpharmacological behavior guidance interventions used for children and youth with special health care needs (CYSHCN) during preventive and dental treatment visits. METHODS: Databases: Ovid MEDLINE, PsycINFO (EBSCOhost), Embase, and Cochrane Library, were searched from 1946 to February 2022, for randomized clinical trials (RCTs) comparing effectiveness of basic and advanced nonpharmacological techniques rendered during a preventive visit (exam, fluoride application, radiographs, and prophylaxis) or a treat- ment visit (simple surgical treatment, sealants, restorative care with or with local anesthesia) with control or other interventions. The primary outcome measures for the studied interventions were reduction in anxiety, fear, pain, and improvement in cooperative behavior. Eight authors determined the included Randomized Controlled Trials (RCTs), performed data extraction, and assessed the risk of bias (ROB). Standardized Mean Difference calculation and assignment of quality of evidence by Grading of Recommendations Assessment, Development and Evaluation approach were done. RESULTS: Eleven articles qualified for analysis from 219 screened articles. Included studies evaluate the effectiveness of in office strategies such as modeling, audio-visual distraction, sensory adapted dental environment, and picture exchange communication system. The certainty of evidence ranged from Very low to Low and the magnitude of effect varied from trivial to large change in the desired outcomes. CONCLUSIONS: Most basic non-pharmacological behavior guidance techniques showed some trivial to small reduction in self-reported anxiety and/ or improvement in behavior, with audiovisual distraction, Sensory Adapted Dental Environment, and Picture Exchange Communication System showing large reduction in anxiety based on some rating scales.

A Prospective Clinical Assessment of BioHorizons Tissue-Level Implants.

This investigation was designed to evaluate crestal bone stability and soft tissue maintenance to Laser-Lok tapered tissue-level implants. Twelve patients presenting with an edentulous site adequate for the placement of two implants were recruited from four dental offices (2 to 4 patients per office). Each patient received two Laser-Lok tissue-level implants placed with a 3-mm interimplant distance according to a surgical stent. The implants were placed so that the Laser-Lok zone sat at the junction between hard and soft tissues. A total of 24 implants were placed, and all achieved satisfactory crestal bone stability and soft tissue maintenance 1 year after receiving the final prosthetic restoration.

Volumetric assessment of changes in the alveolar ridge dimension following guided bone regeneration using a combination freeze-dried bone allograft with collagen membrane or novel resorbable scaffold: A prospective two-center clinical trial.

BACKGROUND: The aim of this study was to examine osseous changes following lateral bone augmentation using a novel scaffold (OV) alone and compare it to combination therapy using freeze-dried bone allograft (FDBA) and resorbable collagen membrane (FDBA/CM). METHODS: Thirty patients completed this 9-months prospective two-center cohort clinical trial. Before surgery and 9-months re-entry, linear measurements were performed, and impressions taken. Cone-beam computed tomography (CBCT) were done at baseline and 9 months. DICOM slice data were converted into volumetric images using 3D Slicer. Following 3D volumetric image construction, pre- and post-op Standard Triangle Language files were superimposed and volumetric data were extracted for a 10-mm region of interest. Linear measurements were compared similarly. RESULTS: Baseline clinical parameters were similar in both groups (4.22 and 4.53 mm for OV and FDBA/CM at -2 mm, respectively). Following treatment, vertical distance from the stent had changed minimally (-0.36 and -0.12 mm, respectively). Similarly, lateral bone gain ranged from 0 to 0.4 mm, for both groups. To the contrary, the CBCT measurements showed a significantly greater increase in horizontal width in the control at -2 mm (0.95 ± 0.2 mm) compared with -0.62 mm for the OV (P = 0.000). Similar changes were observed at -5 mm (0.63 and -0.41 mm, respectively, P = 0.01). Sites volume had increased from 266 ± 149 mm3 to 360 ± 138 mm3 (P = 0.001) for FDBA/CM with negligible changes for OV (from 334 to 335 mm3 , P = 0.952). these between-group changes being statistically significant (P = 0.023). CONCLUSION: FDBA/CM yielded better albeit moderate increase in the volume of the edentulous ridge, while OV scaffolds failed to produce similar results.

The association between personal income and aging: A population-based 13-year longitudinal study.

INTRODUCTION: Population aging is set to increase the elder dependency ratio, causing a rapid increase in healthcare expenditures and financial burden on the government. This study aims to construct an aging score from age-related diseases and to perform longitudinal analyses to examine the association between personal income and aging. METHODS: A total of 86,838 subjects drawn from a community with 384,617 residents in northern Taiwan were examined. Personal income and aging-related diseases were measured from the National Health Insurance database during 1997-2010. Multiple linear regression and stratified analyses were used. RESULTS: Our results indicate that subjects with low personal income (defined as monthly income ≤610 USD) can have high aging scores as calculated by selected aging-related diseases. In stratified analyses, moreover, subjects with low personal income tended to have higher aging scores across different anthropometric groups. The association was particularly evident in subjects >60years old, and they were noted across multiple strata, including those of catastrophic illness as well as type of primary care setting. CONCLUSIONS: This study found evidence for association between low income and aging in a population with compulsory health insurance program, where accessibility barriers were low in terms of health care resources and personal socioeconomic status. The economic inequity causes difference in aging process, which deserves for future interventions.

The effectiveness of a pay for performance program on diabetes care in Taiwan: A nationwide population-based longitudinal study.

Over the past two decades, studies have widely examined the effectiveness of pay-for-performance (P4P) programs by conducting biochemical tests and assessing complications; however, the reported effectiveness of such programs among participants selected through purposeful sampling is controversial. Therefore, the objective of the current study was to analyze the effectiveness of a P4P program on patients' prognoses, including hospitalization for chronic diabetic complications, and all-cause mortality during specific follow-up years by using a nationwide population-based database in Taiwan. Based on 125,315 newly diagnosed type 2 diabetes patient cohort during 2002-2006, two control sets were designed by propensity-score-matching strategy according to participation of P4P program and followed up to 2012. The results indicated that full participants demonstrated the lowest risks of developing complications and all-cause mortality compared with nonparticipants. These findings confirm the long-term effect of P4P programs on full participants and reveal that this effect is not due to confounding variables. The results indicate the importance of performance management and adherence to interventions for patients with chronic diseases in a long-term observation. Comprehensive and continuous care is suggested to improve patient prognosis and quality of care.

Oral health status of children with special health care needs receiving dental treatment under general anesthesia at the dental clinic of Taipei Veterans General Hospital in Taiwan.

BACKGROUND: Oral health is crucial to individual growth and development. However, oral health care is often overlooked in children with special health care needs (CSHCN). We investigated current oral health status and unmet dental needs of CSHCN in Taiwan. METHODS: We performed a retrospective study of consecutive CSHCN cases receiving first-time comprehensive dental treatment under general anesthesia at Taipei Veterans General hospital from 2001 to 2010. We retrieved clinical data including age, sex, types, and severity of disability, caries experience index [decayed, extracted, and filled teeth (deft) index for primary dentition/decayed, missing, and filled teeth (DMFT) index for permanent dentition], malocclusion, and treatment modalities from medical charts for analysis. The correlation between different groups of CSHCN regarding the deft/DMFT indices and treatment modalities was analyzed statistically. RESULTS: Our study included 96 children, ranging in age from 2.4 years to 14.3 years (mean age 6.8 ± 3.3 years). The deft/DMFT index was significantly higher in the younger age group (2-6 years; 13.8 ± 4.3) compared with the older group (> 6 years; 10.5 ± 5.3; p < 0.001). The mean number of total treated teeth was 14.2 ± 3.8, and no differences existed among disability groups (p = 0.528) and age groups (p = 0.992). For the treatment modality, the number of pulp therapies with crown restoration was higher in the younger age group than in the older group. At the time of the study, 53 CSHCN had reached their full permanent dentition. We observed significantly more malocclusion of full permanent dentition in the older age group (91%) than in the younger group (35%; p < 0.001). CONCLUSION: Unmet dental needs and caries experience indices remain high in CSHCN, regardless of the types and severity of disability. However, the younger the age at which CSHCN received their first dental treatment, the more effective the dental rehabilitation was. Parental education regarding early dental intervention and a preventive approach for enhanced oral care is mandatory.
