Sense of coherence and dental fear/dental anxiety: A systematic review and meta-analysis

Patient-related predictors of post-operative pain following root canal treatment: A structural model analysis

AIM

The pathways to post-operative pain are complex and encompass factors that extend beyond the treatment protocol employed. This study aimed to identify patient-related predictors of post-operative pain following root canal treatment.

METHODOLOGY

A total of 154 patients received a single-visit root canal treatment for asymptomatic necrotic mandibular molars. Before treatment, dental anxiety, dental fear and sense of coherence (SOC) were measured as predictors for each patient using validated questionnaires. Other measured predictors included gender, age, previous negative experiences at the dental offices and prior root canal treatment. Post-operative pain was assessed using the Numeric Rating Scale at multiple time-points over 30 days. Structural equation analysis was employed to evaluate the direct and indirect effects of patient-related predictors on a theoretical model of post-operative pain. The irrigant solution was also included in the model, as it was the only aspect that varied in the treatment protocol (sodium hypochlorite 2.5% and 8.25%).

RESULTS

Dental anxiety (coefficient 0.028; p < .01), dental fear (coefficient 0.007; p = .02) and irrigant solution (coefficient 0.004; p = .03) exerted a direct effect on post-operative pain. SOC exerted an indirect effect on post-operative (coefficient 0.006; p = .01) through dental anxiety and dental fear. Moreover, previous negative experiences (coefficient 0.048; p = .04) exerted an indirect effect on post-operative pain through dental anxiety.

CONCLUSIONS

Dental anxiety, dental fear, previous negative experiences and SOC are patient-related predictors of post-operative pain following root canal treatment. These factors should be taken into consideration in clinical practice, as patients with these characteristics may be at an increased risk of experiencing post-operative pain.

Prevalence of negative behaviour in the dental setting and association with sociodemographic, oral health-related and psychosocial factors amongst Brazilian preschool children

PURPOSE

To investigate the prevalence of negative behaviour in preschool children attending dental clinics and its association with sociodemographic, oral health-related and parental psychosocial factors.

METHODS

A cross-sectional study was carried out with 145 parents/guardians and their children aged 4-6 years attending paediatric dentistry training programmes in a capital city of Midwest Brazil. Data were obtained from children's dental records, interviews, and questionnaires for parents/guardians. The outcome was negative child behaviour, based on the dentists' use or indication of behavioural control measures during the dental appointments, as registered in the children's dental records. Covariates were sociodemographic, clinical and parent/guardian psychosocial factors religiosity (DUREL index) and Sense of Coherence (SOC-13 scale). Bivariate analyses and Poisson regression with robust variance were performed.

RESULTS

The prevalence of negative behaviour was 24.1% (95% CI = 17.9-31.7). In the bivariate analyses, the variables initially selected for the regression models (p < 0.25) were the parent/guardians' number of children and religiosity, and the children's dental pain and caries status in deciduous teeth. After adjustment, the prevalence of negative behaviour was 2.12 higher in children with teeth extracted due to caries.

CONCLUSION

The prevalence of negative behaviour was high and associated with the presence of missing teeth due to caries, regardless of sociodemographic, psychosocial, and other oral health factors.

Dentophobia and dental treatment: An umbrella review of the published literature

AIMS

Dentophobia is a well-know kind of phobia and psychological problem in dentistry. Although patients might suffer from severe oral pain and have serious health complications, dentophobia is still posing a threat to oral healthcare and remains an unresolved worldwide phenomenon. According to estimates, up to 80% of the general population are affected by this condition. Dentophobia is an unpleasant problem with serious consequences not only for patients but also for dentists and the public health system in general. This umbrella review provides a comprehensive overview of the various aspects of dentophoia as addressed in the published literature, and the current level of knowledge concerning their treatment.

METHODS AND RESULTS

Based on 35 reviews of the published literature, addressing various aspects of dentophobia and published between 2008 and 2021, this umbrella review was written. The search was based on the PubMed and PsycINFO databases. The extraction was structured by open coding and each aspect of the subject analyzed according to Ritchie and Lewis.

CONCLUSION

We conclude that the evidence concerning the efficacy of the various interventions is still rather weak and there is an obvious need for further research, because of the yet and unresolved challenges and the lack of standardised guidelines to deal with patients with dentophobia.
