Effect of a fluoride varnish on demineralization adjacent to orthodontic brackets

Home fluoride regimens have long been used to reduce the amount of demineralization adjacent to orthodontic appliances. In the absence of patient compliance, another method of applying the fluoride must be used. The purpose of this study was to evaluate, in vitro, the ability of a fluoride varnish, Duraflor, to directly inhibit demineralization of enamel surrounding orthodontic brackets. Brackets were bonded to 36 extracted human canines and premolars with a traditional composite resin and randomly assigned to three equal groups of twelve. Group 1 served as the control with no topical application after bonding. Group 2 was treated with a single application of a nonfluoridated placebo varnish. Group 3 was treated with a single application of Duraflor. All groups were cycled in an artificial caries challenge for 1 hour two times daily for 37 days and were brushed with a medium bristled toothbrush to simulate mechanical wear of the varnish. Demineralization of enamel was evaluated in longitudinal buccolingual tooth sections using polarized light microscopy. Both average depth and area of demineralization were measured with a sonic digitizer. ANOVA (P </=. 0001) and Duncans test (P </=.05) indicated significant differences in depth and area of demineralized enamel. Those teeth treated with Duraflor exhibited 50% less demineralization than the control teeth and an even greater difference when compared to the placebo group. Fluoride varnishes should be considered for use as a preventive adjunct to reduce enamel demineralization adjacent to orthodontic brackets, particularly in patients who exhibit poor compliance with oral hygiene and home fluoride use.

Fluoride, Beverages and Dental Caries in the Primary Dentition

Knowledge concerning risk factors for primary dentition caries in young children is incomplete. Models are presented for caries development using longitudinally gathered fluoride exposure and dietary intake data in the Iowa Fluoride Study. Primary tooth caries examinations were conducted at age 5. Dietary (beverage) and fluoride exposure data were gathered longitudinally from age 6 weeks through 4 years (n = 291); 23% had decayed or filled surfaces. Logistic regression revealed that beverage components and toothbrushing made unique contributions to caries experience. Water consumption (36–48 months), milk consumption (24–36 months), and fluoridated toothpaste brushings (36–48 months) were negatively associated with caries; sugared beverages and milk (6 weeks to 12 months) were positively associated. Although fluoride exposure is important, sugared beverages contribute substantially to caries risk, while water and milk consumption and frequent toothbrushing early can have protective effects.

Lip Biting in a Pediatric Dental Patient After Dental Local Anesthesia: A Case Report

Self-inflicted lip trauma is a potential complication of dental treatment involving local anesthesia of the inferior alveolar nerve, particularly among children. Children presenting with this self-limiting condition are often times misdiagnosed as having a localized bacterial infection. In some extreme cases, children have been unnecessarily hospitalized and treated with systemic antibiotics or surgical interventions. This case report describes a child who bit his lip after a dental appointment and was subsequently hospitalized for monitoring. Pediatric nurses are in a unique position to help parents and primary care physicians properly diagnose and manage this benign condition palliatively.

Emergency department visits and revisits for nontraumatic dental conditions in Iowa

OBJECTIVES To examine the characteristics associated with emergency department (ED) utilization in Iowa for nontraumatic dental conditions (NTDCs), and those associated with having multiple visits to the ED for NTDCs before the Medicaid expansion program in Iowa. METHODS State Emergency Department Database for Iowa was used for 2012, which comprised of all outpatient ED visits in the state. Logistic regression was used for bivariate and multivariable analyses to model the odds of visiting the ED for NTDCs, relative to other conditions, and odds of visiting the ED multiple times relative to a single time in 2012 for NTDCs. The hospital charges associated with the NTDC ED visits were also examined. RESULTS ED visits for NTDCs comprised 1.41% of all ED visits in Iowa during 2012 with a mean charge of

Practices and Attitudes Concerning Oral Health in Pediatric Cardiology Clinics to Prevent Infective Endocarditis

557. Of the patients presenting for NTDCs in 2012, 17% presented multiples times. Young adults, Medicaid enrollees or uninsured, and those residing in metropolitan areas had greater odds of presenting to the EDs for NTDCs compared with other conditions, and presenting multiple times to EDs for NTDCs. Those with more chronic conditions also had greater odds of repeatedly visiting the ED for NTDCs. CONCLUSIONS Low-income young adults in Iowa rely on EDs for their dental needs that can have substantial costs. The Dental Wellness Plan (DWP) is intended to facilitate dental care access by providing dental coverage to low-income Iowans. This study provides baseline data that will be used to evaluate the success of DWP in improving access to dental care.

Dental utilization for medicaid-enrolled adults with developmental disabilities in Iowa residential care facilities

A survey of 121 pediatric cardiology clinics investigated the current practices and attitudes toward oral health education and oral screenings in pediatric cardiology clinics for patients susceptible to infective endocarditis. Most pediatric cardiology clinics do not provide oral health education and oral screenings, but believe it would be beneficial.

Iowa nursing facility oral hygiene (INFOH) intervention: A clinical and microbiological pilot randomized trial

The goal of this study was to evaluate the dental utilization of Medicaid-enrolled adults in Iowa residential care facilities (n=1423). Medicaid enrollment and claims files for 2003 were used, as well as information from the Iowa Department of Inspections and Appeals. Dental utilization was defined as having any dental visit during 2003. Of the residents, 74.1% utilized at least one dental service in 2003. Residents in facilities that were part of smaller organizations, and younger residents, were more likely to have had a dental visit. Of those with a visit, over 80% received a preventive service but this declined with age. Despite additional barriers, dental utilization was generally good for Medicaid-enrolled residents of residential care facilities in Iowa. Residents in smaller facilities of smaller organizations received more personalized care. Older residents were less likely to have a parent involved, were more likely to be edentulous, and sought care less frequently.

Patterns of fluoride intake from birth to 36 months.

PURPOSE/AIM The aim of this pilot study was to evaluate feasibility and gather initial data for a definitive study to test the clinical and microbiological effectiveness of a nursing facility (NF) customized oral hygiene protocol, intended to be delivered by dental hygienists and NF personnel. MATERIALS AND METHODS A convenience sample of 8 Eastern Iowa NFs was recruited, and each NF was assigned to one of three intervention groups: (1) control (current oral hygiene practice), (2) educational program only, and (3) educational program plus 1% chlorhexidine varnish monthly application. Demographic information, systemic health data, patient centered data, oral health data, and microbiology samples were collected at baseline and after 6 months. RESULTS Recruitment response rates were 21% for NFs and 23% for residents. A total of 81 residents were examined at baseline and of those, 49 were examined at 6 months (39.5% attrition). There were no statistically or clinically significant differences among the intervention groups at 6 months for any of the recorded clinical or microbiological outcomes. CONCLUSIONS Recruitment and retention posed a significant challenge to this trial, even with a relatively short observation period. Results from this pilot study did not encourage further investigation of this customized oral hygiene protocol.
