- OBJECTIVE: The aim of the study was to test the hypothesis that root-filled teeth are at a higher caries risk than non-root-filled teeth. MATERIALS AND METHODS: Two sub-samples from epidemiologically obtained data collected in 1983, 1993 and 2003 in the city of Jönköping, Sweden, were analysed. All the participants were examined clinically and radiographically and the type of filling and the presence or absence of caries were recorded. Sub-sample 1 comprised 832 individuals (9202 teeth) aged 20-70 years with at least eight premolars/molars. In sub-sample 2, 163 subjects (577 teeth) with only one or two decayed tooth surfaces and at least one tooth with full crown coverage were analysed. RESULTS: Logistic regression analysis found that root-filled teeth were predictive of recurrent caries when controlling for the type of restoration in sub-sample 1 (OR = 1.68; 1.41-2.0; CI 95%) and sub-sample 2 (OR = 2.20; 1.07-4.52; CI 95%). CONCLUSION: In support of the suggested hypothesis, the data revealed a significant association between root-filled teeth and recurrent caries.

- NTRODUCTION: The aim of the present investigation was to evaluate the caries susceptibility of endodontically versus nonendodontically treated teeth in relation to dental plaque-related factors. METHODS: Twenty patients with 2 endodontically treated teeth (ETT) each were examined regarding cariogenic microflora of proximal plaque, in situ plaque pH drop after a sucrose rinse (Stephan curve), and de novo plaque formation. Recurrent caries and the quality of the coronal fillings/crowns of these teeth were also evaluated. ETT were compared with contralateral, nonendodontically treated teeth (NETT). RESULTS: Irrespective to the type of restoration, Streptococcus mutans count, de novo plaque formation, and recurrent caries were higher on the surface of ETT compared with NETT (P < .05). Moreover, the initial (resting) pH in plaque was significantly lower (P < 0.05) in ETT. CONCLUSIONS: ETT showed an increased susceptibility to caries as a result of either alteration in their biological environment or inadequacy of the marginal fit of the dental restoration. Clinicians should be aware of this risk.

- Less invasive excavation methods have been suggested for deep caries lesions. We tested the effects of stepwise vs. direct complete excavation, 1 yr after the procedure had been carried out, in 314 adults (from six centres) who had received treatment of a tooth with deep caries. The teeth had caries lesions involving 75% or more of the dentin and were centrally randomized to stepwise or direct complete excavation. Stepwise excavation resulted in fewer pulp exposures compared with direct complete excavation [difference: 11.4%, 95% confidence interval (CI) (1.2; 21.3)]. At 1 yr of follow-up, there was a statistically significantly higher success rate with stepwise excavation, with success being defined as an unexposed pulp with sustained pulp vitality without apical radiolucency [difference: 11.7%, 95% CI (0.5; 22.5)]. In a subsequent nested trial, 58 patients with exposed pulps were randomized to direct capping or partial pulpotomy. We found no significant difference in pulp vitality without apical radiolucency between the two capping procedures after more than 1 yr [31.8% and 34.5%; difference: 2.7%, 95% CI (−22.7; 26.6)]. In conclusion, stepwise excavation decreases the risk of pulp exposure compared with direct complete excavation. In view of the poor prognosis of vital pulp treatment, a stepwise excavation approach for managing deep caries lesions is recommended.

- AIM: To assess the adoption of new endodontic technology in a population of Danish practitioners. METHODOLOGY: Members of the Copenhagen Dental Association (n = 1156) were approached with a questionnaire concerning the frequency of various endodontic procedures. Three options were available: often, occasionally and never. Responses were anonymous. The statistical analyses were performed as studies of association in two- or three-way contingency tables, and with Goodman-Kruskal's gamma-coefficient as the basic tool chosen. RESULTS: Only data from general practitioners (GPs) in private practice were analysed (n = 956). The response rate was 72%. NiTi hand instruments were often used to negotiate canals by 18%, whilst 10% often used NiTi rotary systems. Electronic apex locators were often employed by 15%. Nineteen per cent reported that warm gutta-percha was often used. A majority (53%) often spend two sessions to instrument a molar, and 20% often needed three or more sessions to finish the shaping phase. To complete a treatment of a nonvital case most practitioners reported to use at least three appointments. Only 4% frequently applied rubber dam. CONCLUSIONS: The adoption of new endodontic technology is at an early stage amongst Danish GPs. A new revised remuneration system might influence the rate of adoption, allowing the practitioners to act more rationally and produce a higher frequency of good-quality root fillings. Progress towards high quality endodontics might be hindered by the nonuse of rubber dam.

- AIM: To investigate a hypothesized long-time decrease of endodontic treatment in a population with low caries prevalence. METHODOLOGY: A Danish nationwide database including almost all dental diagnostic, prophylactic and therapeutic procedures performed in Danish adults was available. Data on the annual frequencies of root fillings, extractions, pulpotomies, direct pulp cappings and stepwise excavations between 1977 and 2003 were analysed. Data on pulpal and periapical diagnoses were not available and on patients age and gender only from 1996. RESULTS: Between 1977 and 2003 the annual number of root filled canals increased from 268,223 to 364,867 (36%). The annual number of root filled teeth increased from 160,119 to 191,803 (20%). During the period, the annually registered patients increased by 16%. Calculated per 1000 patients, the number of root fillings showed a statistically significant increase of 17%. In root filled teeth the canal/tooth ratio increased from 1.67 to 1.96. Root fillings were frequently recorded in all age groups with the bulk of treatments performed on patients between 40 and 60 years of age. At a total population level, the rate of root fillings decreased among younger individuals and increased among older. The annual number of tooth extractions was more than halved from 656,624 in 1977 to 346,490 in 2003. Pulpotomies decreased markedly over the period and less than 10 treatments per 1000 patients were noted for pulp capping as well as stepwise excavation procedures. CONCLUSIONS: The present study failed to show a long-time decrease of endodontic treatment in a population with low caries prevalence. On the contrary, an increase of root filled canals was observed between 1977 and 2003, which was probably due to a reduction of the tooth extraction rate and an increased treatment of multi-rooted teeth.

- OBJECTIVE: The aim of this study was to study the long-term effect on root filling quality after the introduction of nickel titanium rotary instrumentation (NTRI) within a public dental health organization. STUDY DESIGN: After an education package, including hands-on training and/or lectures, the root filling quality was evaluated at the organizational level. All general dental practitioners (GDPs) employed at primary evaluation (n = 120) and after 4 years (n = 174) were included. RESULTS: The improved root filling quality had been maintained 4 years later. The frequency of excellent root fillings was slightly higher at the long-term follow-up (52%) compared with the short-term follow-up (45%; P = .038). A nonsignificant decrease in very poor-quality root fillings was registered. CONCLUSIONS: A technology shift among GDPs to NTRI will increase the rate of good-quality root fillings. However, the shift per se will not eliminate the problem of substandard clinical performance.

“It′s good enough”: Swedish general dental practitioners on reasons for accepting sub-standard root filling quality
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Aim The concept of “good enough” is central and necessary in the assessment of root filling quality. The aim was to explore the concept by analysing reasons and arguments for the acceptance or rejection of substandard root filling quality as reported by GDPs in Sweden. Methodology The study was designed as a qualitative and exploratory study based on seven videotaped focus group interviews analysed by means of qualitative content analysis. Thirty-three general dental practitioners (GDPs) employed in the Public Dental Health Service in Gothenburg, Sweden, participated (4-6 GDPs/interview). In all nine predetermined questions were followed. Before each focus group, the participants received radiographs of 37 root fillings and were asked to assess the root filling quality. The three cases representing the most divergent assessments served as a basis for the discussion. The cases were presented without clinical information, the dentists would relate to the cases as being just root filled by themselves. Results The radiographs did not provide a sufficient basis for decisions on whether or not to accept the root filling. The present study emphasised that dentists did not primarily look for these arguments in the technical details of the root filling per se but instead they considered selected features of the contextual situation. The GDPs constantly introduced relevant “ad hoc considerations” in order to account for the decisions they made. These contextual considerations were related to aspects of pulpal and periapical disease, risks (e.g. technical complications) or to consumed resources (personal and/or economic). Conclusions It was obvious that the concept of “good enough” does not exist as a general formula ready to be applied in particular situations. Instead, it is necessarily and irremediably tied to contextual properties that emerge from case to case.
