Patterns of emergency maxillofacial referrals and provision of services

The rising number of maxillofacial injuries in the UK requires a reappraisal of emergency services within our specialty. Although the impact of a dedicated trauma list has been reported, it has not been widely embraced, and we know of few data that help to plan the number or timing of such lists. We designed a minimum dataset to collect information about referral, cause of emergency, assessment of patients, and outcome during 2003 and 2004. Theatre data were examined retrospectively to analyse operations during the same period. We conclude that to serve a population of 2.6 million a minimum of 8 emergency lists are required each week to deal with non-complex cases; this equates to 3 lists/million population. The lists should be concentrated at weekends and early in the week.     

Teeth with large amalgam restorations and crowns: factors affecting the receipt of subsequent treatment after 10 years

BACKGROUND: The authors evaluated the factors associated with the receipt of subsequent treatment by teeth restored with a large amalgam restoration or a large amalgam restoration and crown restoration after 10 years. METHODS: The authors used retrospective data from the University of Iowa College of Dentistry (Iowa City, Iowa) administrative database and patient records to evaluate patient and tooth factors for their association with the two primary outcomes: receipt of any subsequent treatment and receipt of catastrophic treatment (extraction, endodontic therapy). RESULTS: The authors followed 518 teeth over a 10-year period (49 percent with large amalgam restorations and 51 percent with crowns). Sixty-four percent of the large amalgam restorations and 32 percent of the crowns received subsequent treatment during the 10 years. In addition to restoration type, the patient's sex, history of grinding teeth and having a broken tooth were related to the tooth's receiving subsequent treatment. Twenty-two percent of large amalgam restorations and 12 percent of crowns received catastrophic treatment with the odds of teeth with large amalgam restorations receiving a catastrophic treatment being 2.1 times the odds of teeth with crowns receiving catastrophic treatment. CONCLUSIONS: Teeth with crowns were less likely to receive any treatment or catastrophic treatment over 10 years than were teeth with large amalgam restorations. Patient and tooth factors also were related to a tooth experiencing subsequent treatment. CLINICAL IMPLICATIONS: Teeth with crowns received less subsequent treatment than teeth with large amalgam restorations. This could be related to both the difference in longevity between the two restorations, as well as how appropriately treatment was planned for each procedure. Cost differences between the two restorations need to be factored into the decision-making process.     

Issues in Financing Dental Care for the Elderly

The elderly make up an increasingly larger segment of the patient population in dental practices. This article reviews recent epidemiologic, demographic, and health services research, and concludes that significant segments of the elderly are at high risk for oral disease and/or limited access to dental treatment, and consequently warrant classification as high-risk groups for policy considerations. It then proposes policy options to the dental community and public decision makers. Oral care can be viewed as having three components. Two basic components are the primary care component--which includes diagnostic, preventive restorative, and periodontal care--and the acute care component--i.e., the treatment of oral pain, trauma, and infection. The third, rehabilitative component, has to do with the restoration of oral function, including prosthodontics and cosmetic dentistry. Viewing dental care in this perspective may help link funding for dental primary care services with that for other primary health services, and link restoration of function and improvement of quality of life with similar health services, like hearing, vision, and social services. In addition, approaching dental care policy makers on several levels--i.e., federal, state, and local--will contribute to our ability as a profession, in the decades ahead, to meet the oral health needs of more elders: including the frail, those at high risk for oral disease, and those with limited access to care.     

Compliance as a prognostic indicator: retrospective study of 505 patients treated and maintained for 15 years

BACKGROUND: The relationship of patient compliance to overall tooth prognosis remains controversial. There are little data, often conflicting, that pertain to tooth loss as a function of patient compliance. METHODS: This retrospective study evaluates the impact of compliance (complete versus erratic) on common periodontal clinical variables, such as probing depth, bleeding index, plaque index, and tooth loss for 505 patients in a long-term period of observation (15 to 23 years) and maintenance therapy (at least 10 years). Compliance was defined in two ways for all analyses. Under the definition for compliance 1, patients who missed <30% of all prescribed maintenance visits were classified as complete compliers. Under the definition for compliance 2, patients who never went 2 years without a maintenance visit were classified as complete compliers. Change in clinical variables was dichotomized into reduction in plaque index versus no reduction, reduction in bleeding on probing versus no reduction, reduction in the percentage of periodontal pockets>3 mm versus no reduction, no increase in decayed, missing, or filled teeth (DMFT) versus increase, and no tooth loss versus tooth loss. The effects of both definitions of compliance were then evaluated in a series of multiple logistic regression models with adjustment for potential confounders. RESULTS: The analysis of the dichotomous change in clinical parameters over time revealed that complete compliers tended to show reduction in bleeding on probing and reduction in plaque index compared to erratic compliers for both definitions of compliance. In contrast, complete compliers under compliance 2 were less likely to have a reduction in the percentage of periodontal pockets >3 mm compared to erratic compliers, whereas complete compliers under compliance 1 had about the same likelihood of demonstrating a reduction in periodontal pockets compared to erratic compliers under this classification scheme. Under both definitions for compliance, complete compliers were more likely to exhibit tooth loss than erratic compliers, with the greatest tooth loss exhibited by complete compliers under the definition for compliance 1. CONCLUSIONS: Based on these results, complete compliers under both definitions tended to show a reduction in plaque and bleeding on probing over time. However, change in periodontal pockets and DMFT over time varied according to the definition of compliance that was used. In addition, the results seem to indicate that the decision for tooth extraction made by dental health professionals at maintenance visits may result in greater tooth loss.
