The treatment-mix, treatment time, and dental status of 268 male industrial workers entitled to employer-provided dental care were studied. The data were collected from treatment records of the covered workers over the 5-year period 1989-93. Treatment time was based on clinical treatment time recorded per patient visit, and the treatment procedure codes were reclassified into a treatment-mix according to American Dental Association categories, with a modification combining endodontics and restorative treatment. The mean number of check-ups followed by prescribed treatment (treatment courses) during the 5 years was 3.7 among those who had entered the in-house dental care program prior to the monitored period (old attenders). Their treatment time was stable, 57-63 min per year, while the first-year mean treatment time (170 min) of those who had entered the program during the study period (new attenders) was significantly higher (P
In forensic odontology, registration of dental characteristics is crucial in the identification procedure. It has been found that the most common errors made are incorrect registration of restorations and confusion about premolars and molars in both jaws. In an earlier study, dental students were observers and the charting was made without radiographs. However, in practical forensic work dentists make the registrations and radiographs are usually available. In this investigation eight dental students and eight dentists made registrations on ten excised macerated jaws with the aid of radiographs. The mean number of errors for each jaw for the students and the dentist was 4 and 3 respectively. The most common error among the dentists was incorrect registration of restorations, while errors on registrations of missing teeth were most common among the students. Even though the material in this study was limited, the results indicate the importance of re-examining of postmortem findings before the comparison with the antemortem data is done. Additionally, the forensic work should be performed by specialists.
Adverse events cause suffering and increased costs in health care. The main way of registering adverse event is through dental personnel's reports, but reports from patients can also contribute to the knowledge of such occurrences. This study aimed to analyse the adverse events reported by dental personnel and patients in public dental service (PDS) in a Swedish county. The PDS has an electronic system for reporting and processing adverse events and, in addition, patients can report shortcomings, as regards to reception and treatment, to a patient committee or to an insurance company. The study material consisted of all adverse events reported in 2010 and 2011, including 273 events reported by dental personnel, 53 events reported by patients to the insurance company and 53 events reported by patients to the patient committee. Data concerning patients' age and gender, the nature, severity and cause of the event and the dental personnel's age gender and profession were collected and analysed. Furthermore the records describing the dental personnel's reports from 2011 were studied to investigate if the event had been documented and the patient informed. Age groups 0 to 9 and 20 to 39 years were underrepresented while those between the ages 10 to 19 and 60 to 69 years were overrepresented in dental personnel's reports. Among young patients delayed diagnosis and therapy dominated and among patients over 20 years the most frequent reports dealt with inadequate treatments, especially endodontic treatments. In 29% of the events there was no documentation of the adverse event in the records and 49% of cases had no report about patient information. The majority of the reports from dental personnel were made by dentists (69%). Reporting adverse events can be seen as a reactive way of working with patient safety, but knowledge about frequencies and causes of incidents is the basis of proactive patient safety work.
Efficiently navigating through an interface and conducting work tasks in flow is what GUI designers strive for. Dental professionals, who alternate between examination and treatment of a patient and insertion of data into the Computerized Patient Record system, particularly need an interface that would facilitate the workflow. In this paper we present an inspection evaluation of an existing and widely used Computerized Patient Record system. The Semiotic Inspection Method was applied with the expectation that the method could provide evidence that task flow, navigation and wayfinding were major usability issues of the interface. Also expected was that the Semiotic Inspection would reveal the means and strategies used in the interface in order to communicate the flow. The analysis conducted using the Semiotic Inspection Method showed inconsistencies in the communication of the way forward through the interface. In addition, the profile of the users, regarding digital skills, appears to be ambiguous. Finally, the strategies used in the interface for conveying the workflow could be identified as well.
A listing and description of longitudinal craniofacial growth record sets currently extant on the North American continent is provided. An argument is made for the preservation of these resources and for the generation of a pooled or shared image base of duplicate craniofacial physical records. This is a preliminary report and is assumed to be incomplete. In an effort to improve our accuracy and completeness, we invite corrections and additions.
In several large epidemiological studies chronic periodontitis has been implicated as an additional risk factor, independent of other risk factors, for the development of ischaemic heart disease. The underlying mechanism is thought to be a localised infection giving rise to an inflammatory host response, and some experimental data agree with this hypothesis. Recently, however, some studies have questioned the post dated relationship between the two diseases. The current case-record study was undertaken to evaluate the prevalence of chronic periodontitis and the severity of such periodontal disease in a heart transplant population, assuming the latter represented a relatively severely compromised cardiovascular patient population. The study demonstrated that 76% of the patients had various degrees of periodontal disease prior to undergoing a heart transplant. Thus, it is possible that a relationship between cardiovascular disease and periodontal disease exists, but further, large intervention studies will be needed to confirm such a conclusion.
The quality of public oral health care, especially the quality of preventive treatment in relation to patients' oral health, was investigated. The population studied consisted of 367 subjects representing the 15-yr-olds living in Helsinki in 1986. Data were taken from the patients' oral health charts, obtained from municipal dental clinics. Clinical examination of the teeth and periodontium had been adequately documented in 98% of cases. In 84% of cases, status recordings matched those recorded previously. Preventive treatment, on the whole, seemed insufficient and stereotyped. Of all patients 55%, and of those in high risk groups only 57 congruent to 60% had had a topical application of fluoride at least once during treatment. Periodontal treatment was insufficient and did not correlate with recorded clinical findings. The results indicate that the concept of prevention and its selective use had not been fully adopted as routine.
