Purpose: This study aimed to investigate the predictors of survival of non‐occlusal non‐incisal glass‐ionomer restorations as a surrogate for root surface restorations among older adults. Methods: In a retrospective cohort analysis using the University of Iowa College of Dentistry electronic dental records, we included 721 patients aged 65+ who received 2+ surface non‐occlusal non‐incisal glass ionomer restorations placed from January 2005 – December 2011. Restorations were followed until September 2017 or until they were deemed to have failed. Results: At baseline, participants' mean age was 77.6 ± 8.2 years, and 45.8% were females. Most patients were self‐pay (65.2%). Most restorations were placed by residents and dental students (82.7%) and included only two surfaces (95.6%). About half (49.1%) failed during follow‐up, with a median survival time of 3.7 years. The time ratio for lower incisors compared to other teeth was 0.6 (p =.006), for three‐and‐four‐surface restorations compared to two was 0.7 (p =.007), for faculty as providers compared to residents and students was 1.4 (p =.039), and for the Geriatric & Special Needs Clinic compared to others was 0.8 (p =.013). Time ratios less than one indicate association with shorter durations for restorations, and time ratios greater than one indicate association with longer durations for restorations. Conclusion: Tooth type, number of restored surfaces, provider type, and clinic were all significant factors associated with survival of these restorations. [ABSTRACT FROM AUTHOR]

A study was conducted to examine the factors that affect outcomes for patients hospitalized for periapical abscess in the United States in 2007. Findings indicate that in 2007, 7,886 hospitalizations were attributed to periapical abscess. Periapical abscess resulted in a total of 23,001 hospitalization days.

Purpose: The purpose of this study was to identify characteristics of hospital-based emergency department (ED) visits for tooth fracture and subsequent dentally related hospital admissions. Methods: This was a retrospective analysis of the Nationwide Emergency Department Sample of the Healthcare Cost and Utilization Project for the years 2008 to 2010. All children up to 21 years old, with a diagnosis of tooth fracture due to trauma, were selected. Hospital ED charges, occurrence of concurrent injuries, and hospitalization following ED visits were examined. Results: A total of 199,061 ED visits were attributed to broken or fractured teeth: males comprised 63 percent of ED visits. Skull and facial fractures were present in seven percent and intracranial injuries in four percent of ED visits. The most frequent causes for ED visits and for subsequent hospitalization, respectively, were falls and motor vehicle accidents. The mean charge for each ED visit was $1,441. Total charges for the entire United States were $241.8 million. Following an ED visit, 7,233 patients were admitted as inpatients. Conclusions: Males comprised a majority of these emergency department visits. Occurrence of concomitant bodily injuries appears to be common and is a significant predictor of hospitalization and hospital ED charges. [ABSTRACT FROM AUTHOR]

Objective: To provide nationally representative estimates of all hospital-based emergency department (ED) visits with dental caries, pulp and periapical lesions, gingival/periodontal lesions, and mouth cellulitis occurring among the older population groups (aged 60 years and above)., Methods: The 2008 Nationwide Emergency Department Sample of the Healthcare Cost and Utilization Project was used. This database provides weighted estimates of all ED visits in the United States (approximately 150 million). Hospital discharges with primary procedure ICD-9-CM codes for dental conditions in adults aged 60 and older were evaluated. All estimates obtained from the sample were projected to national levels., Results: A total of 50,881 ED visits had a dental condition including dental caries (33.6%), pulpal lesions (10.4%), periapical abscess (36%), gingival conditions (11%), and cellulitis (6.7%). Close to 72.7% were discharged routinely and 25.1% were admitted as inpatients into the same hospitals. About 63.4% of ED visits were covered by Medicare. Close to 40% of all ED visits occurred in the southern regions. The mean charge per ED visit was $1,114, and the total charges across the entire United States were $44.8 million., Conclusions: In comparison to other age groups, older adults are hospitalized more frequently after ED visits for dental conditions. As the U.S. population ages, innovative programs are necessary to manage dental conditions in dental offices and reduce the number of ED visits and hospitalizations for dental complaints by older adults.
