Dentists' perception of their treatment practices versus documented evidence.

OBJECTIVE: To compare the quality of real-life treatment practices to dentists' perceptions of treatment rendered. SETTING: One administrative unit of the Finnish public oral health service. METHODS: The original oral health records of a randomly selected sample of young adults who received treatment during 1994-1996 provided data on actual clinical examinations (n=208), radiographs (n=312), and root canal treatment courses (n=148) carried out by 50 dentists. Dentists' perceptions of the treatment rendered were obtained through a structured questionnaire completed during their working hours in 1996. OUTCOME MEASURES: Criteria for assessing the quality of treatment practices were based on Finnish health legislation, authoritative instructions, and consensus reports. RESULTS: Based on responses, 77% of the dentists followed the prevailing instructions on oral health record keeping (82%, if partial agreement included). Most dentists (88% fully agreed, 95% at least partly) perceived that their knowledge gained through continuing education was being applied in practice; no one answered no. A gap was found between dentists' perception of the treatment rendered and everyday treatment practices as recorded on patient documents. CONCLUSIONS: Overall, dentists' perception of the quality of their treatment practices exceeded that found in patient documents. This gap deserves consideration while planning research, education, or quality-improvement projects that relate to dentists' opinions.

Quality evaluation of young adults' radiographs in Finnish public oral health service.

OBJECTIVE: To evaluate the quality of young adults' radiographs exposed and processed under everyday clinical conditions. SETTING: One administrative unit of the Finnish public oral health service. DESIGN: Two reviewers independently evaluated the radiographs by the same written criteria that were designed as a checklist for on-site evaluations, without any further calibration. SAMPLE: In total, 312 radiographs (178 bitewing, 88 periapical and 46 panoramic) from 1990 to 1996, collected from patient documents of a randomly selected sample of young adults born in 1966-1971. OUTCOME MEASURES: Radiographs were assessed by quality indicators pertinent to the clinical utility as acceptable or unacceptable. If erroneous by some indicator(s) but still contributing to the diagnostic information, a radiograph was rated as diagnostically acceptable. A score of quality points was calculated for each radiograph. RESULTS: The overall kappa statistics for intra-examiner reliability was 0.63, the proportional agreement 83%. For inter-examiner reliability, 0.42 and 71%, respectively. Although the evaluation criteria took the clinical utility of the radiographs into consideration, only 15% of bite-wings, 13% of periapicals, and 2% of panoramics received the maximum quality points. Erroneous film positioning was the most common fault on intraoral radiographs. On panoramics, the most frequent faults were in density and contrast and in patient positioning. The radiological evaluation had only been recorded for less than one fifth of the films. CONCLUSIONS: A proportion of radiographs fell short of the ideal. There is room for improvement in the quality of radiography in order to obtain the greatest possible diagnostic yield from the exposed radiographs.

Quality evaluation of process of root canal treatments performed on young adults in Finnish public oral health service.

OBJECTIVES: To evaluate the quality of root canal treatments performed in every-day practice on young adults. METHODS: A quality index related to the treatment process was developed based on the guidelines of the European Society of Endodontology. A random computerised selection of 134 young adults (born 1966-1971) produced 125 (93%) eligible oral health documents, including information on 148 teeth that were root canal treated by 47 dentists. The process of root canal treatment was evaluated according to the original oral health documents. The technical quality of root canal fillings was assessed on postoperative periapical radiographs. RESULTS: The overall Kappa statistics for the inter-examiner reliability of assessments was 0.63; the proportional agreement being 87%. The mean quality index was 6.2, s.d. 2.0, with none of the treatments scoring the maximum 13. On the 56 available postoperative radiographs, 52% of the fillings were optimal, showing a length within 0-3mm from the radiological apex, no voids in the apical part nor lumen apical to the filling. Of the completed 144 root canal treatments, only 11 included some recorded follow-up information within 15months from the termination of the treatment. CONCLUSIONS: The technical quality of the root fillings was similar to that found in previous studies. However, the quality index, paucity of pre- and post-operative radiographs, and the lack of follow-up all indicated a discrepancy between consensus guidelines and every-day practice.

Dentists' selection of measures for assessment of oral health risk factors for Finnish young adults.

Dentists' selection of measures for assessing oral health risk factors for young adults, in relation to their oral health status and to those dentists' characteristics, was studied in one administrative unit of the Finnish public oral health service. A random selection (n = 239) was made of all young adults born in the period 1966-71 and clinically examined during 1994. On the original oral health records of those selected, all notes were scrutinized concerning the most recent clinical examination and treatment course; in total 208 (87%) records. We found that assessment of risk factors to oral health was rare. The patient's diet had been recorded as assessed in 7% of all cases, use of fluoride in 8%, and oral hygiene habits in 14%. No salivary tests were performed; nor was patients' use of tobacco assessed. No correlation was detected between measures used by these dentists and their patients' oral health status (DMFT and DT scores, number of approximal incipient lesions, and number of healthy sextants by CPITN). The oral health status impelled only slightly assessments by bite-wing radiographs. Fewer than half (44%) of the dentists performed and recorded any kind of assessment measure; 4% assessed diet, hygiene, and use of fluoride for all their patients in our sample. A dentist's gender showed no correlation with number of measures used; younger dentists tended to perform and record assessments slightly more often than did older dentists, but in all age groups there were those who had not done this. The practice of risk-factor assessment should be more widespread and standardized, contributing to needs-based treatment and allocation of resources.

Dentists' decisions as to mode of preventive treatment in adolescents and young adults in Finland.

OBJECTIVE: To evaluate dentists' real-life decisions as to mode of preventive treatment in adolescents and young adults, in relation to these patients' oral-health status, and to the dentists' characteristics. DESIGN: A random sample of 206 adolescents and 239 young adults (mean ages 13 and 27 years) produced 411 (92%) individual oral health records providing data on actual clinical examinations and treatment courses carried out by 56 dentists in one administrative unit of the Finnish public oral health service during 1994-1996. OUTCOME MEASURES: Preventive measures were defined as active and passive, active including any kind of motivation or instructions given to a patient concerning home self-care, and passive prevention being topical application of fluoride. RESULTS: More adolescents had received both active and passive prevention than had young adults (active: 27% vs. 20%; passive: 85% vs. 70%). Of adolescents, 7% and of young adults 25% were given no preventive treatment. The mean number of active preventive measures per adolescent during the treatment course was 0.3 and of passive measures 1.0; for young adults 0.2 and 0.8, respectively. A subject's oral health status made no significant difference in active prevention given. Active measures were more frequently given to all patients by male dentists, 35% vs. 22% (P < 0.02), and passive measures by females, 82% vs. 52% (P < 0.001). The odds of active prevention for adolescents were 7.4 comparing male dentists to female; of passive 13.8 comparing female to male. CONCLUSIONS: Dentists should be motivated to make considered treatment decisions on preventive treatment.

Quality evaluation of oral health record-keeping for Finnish young adults.

The objective of this study was to assess the quality of oral health record-keeping in public oral health care in relation to dentists' characteristics. A random computerized selection of 239 subjects, born in 1966-71 and clinically examined during 1994 in an administrative unit of the public oral health service in southern Finland, included 4-5 cases per dentist, the number of dentists being 50. Data concerning actual clinical examinations and treatment courses carried out in public dental clinics came from original oral health records. Criteria for assessment of oral health record entries were based on Finnish health legislation and detailed instructions of health authorities. The results showed that each patient's identity was available in 90% of documents. Recordings concerning continuity of comprehensive care were infrequent; a questionnaire concerning each patient's up-to-date health history was in only 26% of the oral health records. Notes concerning each patient's bite and function of the temporomandibular joint were in 37% of the records, notes about oral soft tissues were in 11%, and the check-up interval was recorded in 21%. Recording of indices on periodontal and dental status varied greatly; the community periodontal index of treatment need was found in 93% and the index of incipient lesions in 16% of the records. Female dentists and dentists younger than 37 years tended to record more information. Dentists should be encouraged to better utilize the options offered by oral health records for individual treatment schemes.
