Patient-Specific, Risk-Based Prevention, Maintenance, and Supportive Care: A Need for Action and Innovation in Education

Improving predoctoral education related to caries risk assessment in adults

OBJECTIVES

This project examined patterns of adult patient management using a caries risk assessment (CRA) protocol at East Carolina University, School of Dental Medicine. Usage of the CRA protocol from 2014 to 2019 was assessed. Non-operative anti-caries treatments were measured against caries risk status (high, moderate, low, or none). Steps to improve the appropriate management of patients based on caries risk are presented to align with accreditation standards for predoctoral education programs.

METHODS

The CRA protocol is based on the Caries Management by Risk Assessment approach. Risk-based patterns for two non-operative interventions were examined: (1) prescriptions for 0.12% chlorhexidine gluconate (CHX) mouth rinse and (2) prescriptions for 5000 ppm fluoride toothpaste (PreviDent 5000 [PreviDent]). Statistical analyses included chi-square tests and logistic regression.

RESULTS

Over the study period only 16.4% of adult patients had completed the CRA form. Among 29,411 patients from nine community sites, treatment rates for PreviDent were 18.7% among high-risk patients, 11.6% for moderate-risk adults, and 6.4% for low-risk adults (p < 0.01). Treatment rates for CHX were 23.0%, 22.6%, and 17.1%, respectively (p < 0.05). Patients without a CRA status were least likely to receive any anti-caries treatments, indicating that CRA status affects clinical, non-operative care.

CONCLUSIONS

Patterns for prescription of PreviDent and CHX are consistent with CRA status. Future efforts to improve usage of the CRA protocol using faculty calibration, tracking with quality improvement tools, and reassessment. Training in the community-based educational setting is enhanced through data-based tracking to assure evidence-based decision making.

Attachment systems for mandibular implant-supported overdentures: A systematic review and meta-analysis of randomized controlled trials

STATEMENT OF PROBLEM

Although mandibular implant-supported overdentures have been highly recommended as a treatment option, a consensus on the type of attachment systems that can be used to increase implant and prostheses survivability is lacking.

PURPOSE

The purpose of this systematic review and meta-analysis was to compare different types of attachments for retention by investigating outcome measures such as implant and prosthesis survival rates and biological and prosthesis complications in participants with a mandibular implant-supported overdenture.

MATERIAL AND METHODS

The search was performed in the PubMed, Cochrane, Embase, and Scopus databases by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria and registered with the International Prospective Register of Systematic Reviews (CRD42021253566). An analysis of association was conducted between different attachment systems and implant and overdenture survival rates in randomized controlled clinical trials.

RESULTS

The initial search indicated 477 studies, of which 25 randomized controlled trials (RCTs) were included for analysis. A total of 2154 implants and 737 overdentures were analyzed in the meta-analysis. The main results indicated the failure rate for dental implants to be 2.0% (95% confidence interval [CI], 1.3 to 3.2) and overdentures 4.2% (95% CI, 1.6 to 10.5), respectively. With regard to different attachment systems, a similar failure rate was identified with bar-type retention (7.7% to 95% CI, 3.0 to 18.1), magnetic retention systems (7.6% to 95% CI, 2.2 to 22.7), and ball-type retention (6.8% to 95% CI, 3.0 to 14.3). No significant difference was found in biological complications for splinted and unsplinted implant overdentures (P=.902). Regarding prosthetic complications, the most favorable groups were LOCATOR attachments followed by telescopic and Conus, bar, and ball attachments. Magnet attachments had higher prosthetic complications (7.4 times) than the other attachments.

CONCLUSIONS

Implants and implant-supported mandibular overdentures showed a high survival rate irrespective of the attachment system used. Splinting implants did not significantly affect the rate of biological complications. Prosthetic complications were most common for magnet and least common for LOCATOR attachments.

Investigating periodontal diagnosis and treatment at one dental school

INTRODUCTION

The purpose of this study was to evaluate whether patients at one dental education institution received appropriate care based on their periodontal diagnosis in a timely manner.

MATERIALS AND METHODS

This study used a retrospective design to evaluate data from July 2018 to February 2020. The patient records were screened to determine whether patients received a periodontal diagnosis, whether the diagnosis followed the 2018 AAP Classification Guidelines, and if appropriate preventive and therapeutic procedures were completed in a timely manner. In addition, the type or year of dental student providing the procedure was also recorded. Data were analysed using descriptive statistics and a Chi-squared test.

RESULTS

A total of 612 charts were generated for review and 157 met the inclusion criteria and were evaluated. Results revealed that more than half (56.7%) of the patient records did not demonstrate a periodontal diagnosis and another 10.8% did not follow current AAP Classification Guidelines. Most patients (n = 125, 79.6%) had a comprehensive periodontal assessment performed, while 32 (20.4%) had no comprehensive periodontal charting information recorded. Further, of the 157 records reviewed, 96 (61.1%) had no periodontal treatment specified. A statistically significant difference with a modest association was found between type of dental student and year based on periodontal diagnosis (Fisher's exact test value = 20.72, p = .001, Cramer's V = 0.25).

CONCLUSION

Documentation of key clinical information, diagnostic conclusions, and treatment rendered requires curriculum review. Further studies are warranted to determine whether similar findings exist among other dental school education programs.
