This study explored the variation between examiners in the orthodontic treatment need assessments of fifth-grade children with a borderline orthodontic treatment need. Each of three groups of children with borderline treatment need (n = 18, 19, and 19, respectively) were examined by one of three groups of orthodontists (33 in each group), whereby each of 56 children had 33 orthodontic treatment need assessments based on a clinical examination. This treatment need determination exercise was subsequently repeated with treatment need determined based on study casts and extraoral photographs. The proportion of positive treatment decisions based on the clinical examination was 49.3, 49.6, and 52.5 per cent, respectively, and 45.7, 46.3, and 50.5 per cent, based on the model assessments. There was a considerable disagreement between examiners in the treatment need assessments, whether assessments were based on a clinical examination or on a model-based case presentation. The average percentage agreement between two orthodontists for the treatment need based on clinical examination was 69, 66, and 61, respectively, corresponding to mean kappa values of 0.38, 0.32, and 0.22. When the model-based assessments were considered, the average percentage agreement between two orthodontists was 62, 58, and 69, respectively, corresponding to mean kappa values of 0.25, 0.16, and 0.37. Linear regression analysis of the orthodontists’ treatment propensity as a function of their gender, place of education, years of orthodontic treatment experience, type of workplace, and place of work showed that only the orthodontic experience was influential for the model-based treatment propensity [β = 0.34 per cent/year (95 per cent confidence interval = 0.01–0.66)].

Objectives: It is not clear if or how the incidence of systemic conditions like type 2 diabetes mellitus (DM 2 ), rheumatoid arthritis (RA) or inflammatory bowel disease (IBD) affects dental service utilization. Using nationwide Danish register data, the aim of this study was to analyse the use of dental services 7 years before and after being diagnosed with DM 2 , RA or IBD between 1997 and 2011., Methods: Information about incident DM 2 was obtained from the Register for Selected Chronic Diseases and Severe Mental Disorders, and incident RA and IBD were defined based on diagnosis codes of hospital contacts identified through the National Patient Register. Separately, for each of the three conditions, each individual with the incident condition was matched to one control individual based on age, gender, country of origin, municipality of residence, highest completed education, the main source of income and income using coarsened exact matching in the year of incidence. The use of dental services and treatments received within each calendar year from 7 years before to 7 years after getting the condition were analysed with generalized estimating equations., Results: People with incident DM 2 were less likely (by seven percentage points) to be dental service users within a year than people without incident DM 2 for a period extending from up to 7 years prior to 7 years after the diagnosis. This difference even slightly increased after the diagnosis. Those with incident IBD exhibited a consistently but modestly higher proportion of dental service use (three percentage points) than those without incident IBD before and after the diagnosis. Differences in the use of services between those with or without incident RA were minor. For all three systemic diseases, detected differences mainly mirrored differences in the provision of supragingival scaling and restorative treatment., Conclusions: The findings suggest that the impact of these three systemic conditions on dental service use was minor., (© 2024 The Authors.

The cost of dental care adds to the costs of the already overburdened health sector. Do we - as patients and as society -receive oral health care that is both aligned with the actual disease experience and also, critically based on up-to-date scientific knowledge about the major oral diseases? In many places, the practice of dentistry reflects a response to disease patterns that once existed and is based on diagnostic and therapeutic approaches that are no longer valid. Instead, a new cadre of dental professionals is needed, one that is capable of meeting the actual health needs of our populations. This cadre should ensure that patients maintain a functioning dentition from cradle to grave based on cost-effective disease control principles. There is an urgent need to: (i) reconsider the roles of the different oral health cadres involved in the provision of oral health care; (ii) integrate oral health into general healthcare services; and (iii) restructure the training of oral health personnel. We advocate a radical reform of the oral healthcare system involving the training of two new types of professionals integrated with the general healthcare system: The oral healthcare provider - a highly skilled professional specialised in the diagnosis and control of oral diseases and with a profound understanding of oral health as part of general health - and the oral clinical specialist - whose role is the provision of advanced oral rehabilitation, able also to treat people with complex chronic diseases and multiple medications., (© 2013 John Wiley & Sons Ltd.)

The optimal tools for obtaining a diagnosis of dental agenesis (DA) among adults are childhood dental records and radiographs. However, these are often not available, and therefore the present study aimed to assess whether DA in adults could be validly assessed by self-reported information guided by a questionnaire. A questionnaire eliciting information on DA of permanent teeth was constructed, pilot-tested, and subsequently posted to a case group consisting of 334 young adults, for whom the DA status had been ascertained in the period from 1992 to 2002. A control group, consisting of 258 young adults randomly selected from the population from which the cases originated, was also approached with questionnaires. The response rate was 53.7% among cases and 46.4% among controls. The sensitivity and specificity of self-reported DA were estimated to be at least 0.88 (95% CI = 0.82-0.92) and 0.95 (95% CI = 0.89-0.98), respectively. These diagnostic test parameters are clearly inadequate for population-screening purposes. However, when screening patient groups with a higher occurrence of DA than is characteristic of the background population, the self-reported DA status may be a useful tool for identifying risk groups for conditions associated with the presence of DA., (© 2011 Eur J Oral Sci.)

The aim of this study was to test whether the concentrations of fluoride in fluorotic human enamel are related to the degree of severity of dental fluorosis classified according to the index described by Thylstrup and Fejerskov. Teeth representing the entire spectrum of human dental fluorosis were analyzed. Fluoride concentrations were determined by serial acid-etching from surface to interior of blocks of enamel cut from each tooth. Fluoride was measured by ion electrode and calcium by atomic absorption spectrophotometry. The results showed that the pattern of distribution of fluorotic enamel is similar to that described for normal enamel. Increasing severity of fluorotic lesions was associated with increasing concentrations of fluoride throughout the enamel. It is concluded that although further studies are required to establish the relative contribution of fluoride which may be taken up posteruptively by fluorotic enamel, the findings support the hypothesis that the TF index reflects increasing exposure to fluoride during tooth development.
