Traumatic dental injuries among children attending the public after-hours emergency dental clinic in Bergen, Norway.

OBJECTIVES: To investigate traumatic dental injuries (TDIs) among children who for 1 year attended a Norwegian public after-hours emergency public dental (EPD) clinic. MATERIALS AND METHODS: The study included 7-18-year-olds (n = 312) who presented at the EPD clinic, underwent a clinical dental examination, and consented to the disclosure of clinical information. Recording of TDIs was restricted to anterior permanent teeth. Potential TDI predictors were also analysed. RESULTS: Almost half (n = 148) of the children were assessed with TDIs in permanent teeth, showing a mean age of 11.0 (standard deviation [SD]: 3.5) years. Males constituted 54.7%. The children experienced TDIs often outside school hours (43.9%), and the majority (58.1%) were caused by falls/accidents. Sixty of them experienced only one TDI. The most common location was the maxillary central incisors. Assessment of TDIs according to severity, could only be done in 131 individuals, involving 253 TDIs. Of these, 81.8% were mild. The odds of visiting the emergency clinic for a TDI were higher (odds ratio [OR] = 2.64, confidence interval [CI]: 1.61-4.31) among children with previous TDIs and lower (OR = 0.28, CI: 0.12-0.68) among those with poor dental attendance. CONCLUSIONS: Traumatic dental injuries were a common reason for seeking emergency care. Milder injuries dominated and involved mostly one maxillary central incisor. Previous episodes of TDIs and attendance patterns seemed to be associated with seeking care for TDIs.

Orthodontic management of traumatic dental injuries in Norway and orthodontists' perceptions of referral routines: A quality assurance survey.

BACKGROUND/AIM: Orthodontic treatment of patients with traumatic dental injuries is challenging, with limited evidence of routines and outcomes. The aims of this study were: (i) to describe how orthodontists perceive the information on traumatic dental injuries received by referral from the Public Dental Health Service before orthodontic treatment and (ii) to assess orthodontists' knowledge and working routines in managing traumatic dental injuries. MATERIALS AND METHODS: Data were obtained through a survey of all practicing orthodontists registered as members of the Norwegian Association of Orthodontists (n = 203). RESULTS: Eighty-three orthodontists were enrolled, most of whom had received their dental degree (73.0%) and specialist orthodontic training (88.5%) in Norway. They reported examining patients with a history of traumatic dental injury at weekly (34.2%) or monthly (38.0%) basis. In 85.5% of cases, they obtained a history of traumatic dental injury from patients. Half of the respondents (51.3%) favoured two-phase early orthodontic treatment for patients with an overjet ≥6 mm. The observation time and treatment strategy showed considerable discrepancies across traumatic dental injury diagnoses. Most (59.1%) orthodontists considered the information on previous traumatic dental injuries provided by the Public Dental Health Services referral 'inadequate', more commonly in cases of mild (83.5%) than severe (57.5%) traumatic dental injuries. CONCLUSIONS: Orthodontic management of patients with traumatic dental injuries was characterised by lack of uniformity in both recommended observation time before orthodontic treatment and management strategy. The referral routines by the Public Dental Health Services for patients with traumatic dental injuries were perceived as 'inadequate' in terms of frequency and quality. The results indicate the requirement of standardisation of routines related to orthodontic management of traumatic dental injuries and referral routines by the Public Dental Health Services.

Regional variations in caries experience, predictors, and follow-up among children and adolescents in Western Norway.

OBJECTIVE: To identify regional differences in, and determinants of dental caries among children in western Norway. MATERIAL AND METHODS: We studied dental caries in 705 children aged 12 years and 18 years living in the southern region (n = 403) and other parts of Hordaland County (n = 302) in Norway. Information on oral hygiene, fluoride intake, and sugar consumption was collected using questionnaires. We also collected information from the Public Dental Service (PDS) on the history of decayed, missing, or filled teeth; professional fluoride application; recall and regular check-up intervals and treatment visits. Residence (southern region versus the rest of Hordaland, the reference) was the independent variable. We analysed regional differences in (i) caries prevalence and severity, (ii) potential contributors to caries, and (iii) procedures and routines in PDS. RESULTS: Caries prevalence and severity were higher in the southern region (67% and 24%, respectively). Self-reported brushing habits, fluoride use, and sugar consumption patterns were similar between regions. We observed more frequent application of professional fluoride (incidence rate ratio [IRR] = 3.05, 95% CI: 1.99-4.66], fewer check-ups [IRR = 0.88, 95% CI: 0.81-0.95], and fewer treatment visits [IRR = 0.77, 95% CI: 0.60-0.98] among participants in the southern region, compared to the rest of Hordaland. The recall intervals in the southern region were 10% longer among 12-year-olds and 10% shorter among 18-year-olds, compared to their respective counterparts in Hordaland. CONCLUSIONS: The observed regional gradients in caries experience mirrored regional differences in dental routines and procedures. Caries-related risk behaviours did not explain the observed differences in caries experience.

Exploring avoidance of dental care due to dental fear and economic burden -A cross-sectional study in a national sample of younger adults in Norway.

AIM: To assess the prevalence of dental avoidance due to dental fear and economic burden and its distribution by utilization of dental care and socio-behavioural characteristics. METHOD: A sample of 9052 Norwegian adults aged 25-35 years was invited to participate, and 2551 completed electronic questionnaires regarding lifetime prevalence of dental avoidance due to fear and last year prevalence of dental avoidance due to economic burden. RESULTS: Cancelled- and avoided ordering appointments due to fear amounted to 14.7% and 30.5%, respectively. Avoidance of dental visits due to cost was 37.7%. Frequency of cancelled appointments due to fear was 30% and 16.6% among participants attending dental care several times annually and seldom, respectively. Multiple logistic regression revealed that avoiding dental visits due to cost was less likely among participants with higher household income (OR 0.4, 95% CI 0.3-0.5) and more likely among participants with dental care need (OR 1.8, 95% CI 1.2-2.7). Cancelled and avoided appointments due to fear was most likely among those with need for dental care and lower education. Early unpleasant experience with dental care remained a covariate of avoidance behaviour due to fear. CONCLUSION: 14.7%, 30.5%, and 37.7% confirmed cancelled appointments due to fear, avoided ordering appointments due to fear, and avoided visiting the dentist due to cost. Avoiding dental care due to fear and economic burden was more and less common among participants with respectively, frequent and seldom use of dental care. Dental avoidance behaviours were highest among socially disadvantaged groups, indicating a hole in the welfare state model that needs political consideration.

Work experience influences treatment approaches in endodontics: a questionnaire survey among dentists in Western Norway.

Objectives: To collect information on endodontic treatment procedures among dentists in the public dental service (PDS) in Western Norway and relate this information to their work experience. Materials and methods: A survey comprised of 35 questions related to personal information, frequency of endodontic treatment, endodontic procedures and treatment principles was distributed electronically to 187 dentists in PDS in two counties of Western Norway. Results: The response rate was 74%, and 130 dentists participated. Among them, 57.0% had completed their education less than 13 years ago, and almost all were below 39 years old (95%). The majority (81.0%) had graduated in Norway. Stepwise caries excavation in primary and permanent teeth and direct pulp capping in primary teeth were more frequently performed by dentists with less than 13 years from graduation. Routine use of rubber dam was high among the responders (87%). However, use of rubber dam and master-cone radiograph uptakes were more frequent among the younger dentists. The majority used rotary instrumentation systems, and almost all participants followed the current guidelines for use of antibiotics in endodontics. Conclusions: In general, dentists in PDS follow the current endodontic treatment guidelines. However, it seems that the more recently graduated dentists perform more endodontic procedures and tend to adhere more to the taught principles regarding rubber dam use and radiograph uptakes.

Radiographic features in 2D imaging as predictors for justified CBCT examinations of canine-induced root resorption.

OBJECTIVES: This retrospective observational study aimed to evaluate the diagnostic accuracy of two-dimensional radiographs on canine-induced root resorption (CIRR) in lateral incisors and identify predictors of CIRR in patients with impacted maxillary canines (IMC). METHODS: Ninety-nine patients aged 9-17 years, with 156 IMCs, were included in the study. All had CBCT-volumes and two-dimensional radiographs consisting of at least one panoramic radiograph. Two radiologists jointly viewed all cases twice. First, radiographic features related to the IMC and possible CIRR were recorded from two-dimensional radiographs. Then, CIRR was determined from CBCT and according to position and extension classified as mild, moderate and severe. RESULTS: CIRRs was detected in 80% of lateral incisors (mild: 45%; moderate: 44%; severe: 11%). The sensitivity was generally low at mild and moderate cut-offs (29 and 29%), and somewhat higher for severe (50%). Corresponding specificities were 48%, 63% and 68%. Canine cusp-tip superimposing the lateral incisor's middle third and root/crown ratio >1 was positively associated with mild CIRR, with an odds ratio (OR) of 3.8 and 6.7, respectively. In addition, the root development stage was positively associated with moderate/severe CIRR when the canine root was nearly or fully developed (OR = 3.1). CONCLUSIONS: The diagnostic accuracy of two-dimensional radiographs was inadequate for detecting CIRR amongst patients referred for CBCT examinations. Based on our results, none of the suggested two-dimensional radiographic features could predict moderate/severe CIRR except for root development stage. IMC in a later stage of root development seems to be associated with a higher risk of moderate/severe CIRR.

Early-life course factors and oral health among young Norwegian adults.

OBJECTIVE: Using a national sample of young Norwegian adults, we examined whether unpleasant experience with dental care during childhood is associated with tooth loss and oral health-related quality of life in adulthood after accounting for early- and later-life socio-behavioural circumstances and dental avoidance behaviour. METHODS: 2433 individuals aged 25-35 years participated in an electronic survey. Oral quality of life was measured using the oral impact of daily performance (OIDP) inventory. Generalized linear models and negative binomial regression models were used to estimate the association of early unpleasant experiences with dental care and tooth loss and OIDP scores. Incidence rate ratio (IRR) and 95% confidence intervals (CI) were used to estimate the relative differences in prevalence of tooth loss and OIDP scores. RESULTS: Adjusting for early-life characteristics only, the prevalence of tooth loss was 1.42 (IRR = 1.42, 95% CI: 1.24-1.64) and 1.96 (IRR = 1.96, 95% CI: 1.70-2.26) times higher among individuals who reported unpleasant experiences a few times or several times, than in individuals who did not report unpleasant experiences with dental care in childhood. Adjusting further for educational level, smoking and tooth brushing attenuated the relative differences (IRR = 1.40, 95% CI: 1.22-1.62 and IRR = 1.88, 95% CI: 1.62-2.17, respectively). Lastly, when adjusting for dental avoidance behaviour, the prevalence of tooth loss was 1.29 (IRR = 1.29, 95% CI: 1.11-1.50) and 1.58 (IRR = 1.58, 95% CI: 1.32-1.88) times higher among individuals who reported unpleasant experiences a few times or several times than in those who did not. Corresponding associations of early unpleasant experience with OIDP were (IRR = 1.41 95% CI: 1.22-1.63) and (IRR = 1.69, 95% CI: 1.42-2.01) when adjusting for early-life characteristics, and (IRR = 1.39, 95% CI: 1.20-1.60) and (IRR = 1.51, 95% CI: 1.27-1.80) when adjusting for education, smoking and tooth brushing. When adjusting for dental avoidance behaviour, the association of early unpleasant experience with OIDP became nonsignificant. CONCLUSION: Unpleasant dental care experiences during childhood are associated with poor oral health in adulthood, independent of later-life socio-behavioural characteristics including negative dental care seeking. This highlights the importance of tailoring regular contacts with dental healthcare services in childhood to build confidence in children and thus has implications for healthcare policy.
