Minimal intervention dentistry for early childhood caries and child dental anxiety: a randomized controlled trial

Performance of restorations in primary molars over a seven-year period

OBJECTIVE

The aim of this study was to evaluate the use and reintervention rate of fillings compared to preformed metal crowns in the everyday clinical practice of German dentists.

METHODS

In this retrospective, longitudinal analysis, fee codes from the Kassenzahnärztliche Vereinigung Westfalen-Lippe for restorations placed in primary molars between 2012 and 2015 in children until 7 years of age followed for a 7-year period (latest until December 2022) were filtered and analyzed with the Fine and Gray competing risk regression and Cox proportional hazards regression to calculate the risk of reintervention divided into the main outcomes "Successful", "Minor Failure/Repair" and "Major Failure/Endodontic Treatment/Extraction". 367,139 primary molars (one-surface fillings: n = 117,721; two-surface fillings n = 198,815; three-surface fillings n = 36,695; more than three-surface fillings n = 8,267 and preformed metal crowns n = 5,641 were included in this study.

RESULTS

Teeth treated with preformed crowns needed significantly less re-interventions. Subdistribution hazard ratio for minor events was 0.117 (95 %-CI: 0.097 to 0.141) and hazard ratio of major events (HR=0.786; 95 %-CI: 0.695 to 0.890) when compared to one-surface fillings in multivariable adjusted analysis. Within 7-year follow-up preformed crowns required less repairs (80.6 % success rate, minor failure 4.4 %, major failure 16.3 %) than the teeth treated with composite fillings (46.2 %-52.6 % success rate, minor failure 27.0 %-39.5 %, major failure 15.5 %-28.4 %, p < 0.001).

CONCLUSION

Within the German healthcare system fillings are the first choice for treating primary molars despite considerably higher reintervention rates. This encourages a discussion on the indication of fillings and the more durable preformed metal crowns to reduce unnecessary reintervention in young children.

CLINICAL SIGNIFICANCE

This study gives an unprecedented insight into the German healthcare system regarding the reintervention rates of the most relevant treatment techniques for caries in primary molars.

The Impact of Minimal Intervention Dentistry on Patient-Reported and Observation-Based Outcomes in the Pediatric Population: A Systematic Review and Meta-Analysis

This review aimed to systematically investigate the effect of minimal intervention dentistry on patient-reported and observation-based outcomes of anxiety, pain and patient cooperation in the pediatric population. Microinvasive treatments (MITs) were compared to conventional treatments, home-based and professionally applied non-invasive treatments (NITs), and between MITs. Two reviewers independently screened studies from four electronic databases, extracted data, assessed the risk of bias and certainty of evidence with the GRADE approach. Ultimately, 26 studies were included for qualitative synthesis, with the data from 12 studies being incorporated into the meta-analysis. No statistically significantly differences in terms of anxiety were noted between MITs and conventional treatments, or between MITs from the meta-analyses. The treatment durations of MITs were not necessarily shorter than conventional treatments but varied with the use of local anesthesia, behavioral and clinical approach, and other confounding factors. The certainties of evidence were deemed low due to high risk of bias of the included studies. NITs evoked less anxiety and pain compared to MITs. Minimal intervention dentistry is an alternative treatment to manage dental caries among children and does not arouse different levels of dental anxiety and pain compared to other treatment modalities. However, further well-designed studies are required to draw an evidence-based conclusion.

Children's Dental Fear: Occurrence Mechanism and Prevention Guidance

Children's dental fear (CDF) has become one of the main reasons affecting the quality of dental treatment. In order to reduce the incidence of CDF in China before and after children's dental visits, this review applies literature analysis and empirical summary methods to analyze and summarize academic discussions on this topic, including occurrence mechanism, prevention guidance, and the conclusion that the occurrence and prevention of CDF is closely related with children's internal characteristics and external influences. In the end, we propose a breakthrough of combining the CFSS-DS scale and three-grade prevention theory together in the future to provide new ideas and hypotheses for the prevention of CDF.

Dentophobia-latent Component Factor Analysis of Dental Concerns Assessment Scale

BACKGROUND: Dentophobia (DF) is unreasonable, irrational, excessive, and socially limiting fear of specific situations related to dental care. The condition is part of the ultimate and pathological cluster of dental anxiety. AIM: Objectives of the present study are: (1) Identification of latent factors in the psychological manifestation of dental fear, anxiety, and phobia and (2) comparison of these factors with the degree of manifestation of the psychological construct and gender differences. METHODS: A cross-sectional online-based survey was conducted. The primary sociological information is collected through a direct individual survey including 32 items divided into four sections. Statistical data processing includes descriptive statistics, non-parametric hypothesis tests, exploratory and confirmatory factor analysis for detection and verification of latent factors, internal validity analysis. DISCUSSION: The presence of a latent factor conditionally describing “pain related fear” is a possible reason for the overlap of DF with other panic disorders related to medical care described in the literature. A study performed for a wider and diverse population sample would produce more credible findings from which to draw more accurate conclusions. CONCLUSION: This study provides a better understanding of how to identify patients who are prone to, or already suffer from dental anxiety and allows dentists and health-care professionals to provide better health. The analysis of this study discovered a significant difference between latent factors from the construct encompassing the pain related fear and social fear.

Diagnostic accuracy, available treatment, and diagnostic methods of dental caries in practice: a meta-analysis

Background

Diagnosis of dental caries and identification of patients with dental caries is the biggest challenge in dentistry. For this diagnostic accuracy, several methods are studied. The present study attempts to re-study the published data in the last 50 years, between 1960 and 2020.

Main body

Based on designed keywords, we made a thorough search of 4 different databases and found 3887 articles after removing the duplicate. The included database was PubMed, Ovid, Web of Science, and Cochrane library. On keen screening of the articles, we included 19 articles in the review. All the articles were analyzed based on the Cochrane risk assessment method. Maximum studies of up to 80% of caries management are based on children from 1 to 10 years of age. About 47% of articles were found based on reported use of drugs against dental caries, whereas 52.6% of articles were based on the behavioral and socio-demographic study of the mother and caretakers. We found that attentive parents and caretakers of the children can help in reducing the prevention of caries. Frese et al. (Sci Rep. 8(1):16991, 2018. 10.1038/s41598-018-34777-x), Liu et al. (PLoS ONE 8(11):e78723, 2013. 10.1371/journal.pone.0078723), and Innes et al. J Dent Res 99(1):36–43, 2020. 10.1177/0022034519888882) were the studied articles with high quality and low bias risk. These methods were based on the use of stannous fluoride for dental caries, the study of the effect of smoking on older adults, by checking the anxiety level of the participants.

Short conclusions

Tooth decay is a common condition in the general population and affects mostly children. The method with high accuracy and low risk can be recommended for routine treatment.

A scoping literature review on minimum intervention dentistry for children with dental caries

Background Dental caries in children's permanent teeth remains a global burden. In contrast to the traditional approach of treating the disease through surgical operative intervention, minimum intervention has increasingly been recommended for managing children with dental caries.Aim This scoping review aimed to describe the literature related to the provision of minimum intervention dentistry for children with caries and to identify research gaps.Methods Electronic databases (Medline via Ovid, PubMed, Web of Science and Scopus) were searched, together with grey literature databases, and key organisation websites. Data was extracted on a piloted extraction template and a thematic analysis was undertaken.Results Sixty-seven relevant articles were identified. No empirical literature was identified that assessed a complete minimum intervention care pathway to managing caries. Five themes were identified from the scoping literature: evidence base, clinician attitude and skills, practice implementation, acceptability and environmental factors.Conclusions The majority of articles were opinion papers. There is a paucity of empirical evidence supporting the clinical and cost-effectiveness of a minimum intervention pathway for children with dental caries in primary dental care. The scoping review has identified some potential barriers to the implementation of such a care pathway, including regulatory and remunerative frameworks and clinical training/education.

Survival estimates of atraumatic restorative treatment versus traditional restorative treatment: a systematic review with meta-analyses

Objectives The hypothesis tested was that there is no significant difference between the survival estimates of atraumatic restorative treatment/high-viscosity glass-ionomer cement (ART/HVGIC) restorations, in posterior primary and permanent teeth, and traditional amalgam and resin composite restorations.Data sources The databases PubMed, DOAJ, LILACS, IndMed, Google Scholar and CNKI were searched.Data selection Using inclusion and exclusion criteria led to 14 eligible randomised trials. A low risk of bias was observed for two reports. Homogeneity was obtained for single-surface ART restorations after one and two years in the primary dentition.Data synthesis No statistically significant difference was found between the weighted mean survival percentages of ART/HVGIC and traditional treatments in both single- and multiple-surface restorations in primary molars and in single-surface restorations in posterior permanent teeth at years 1, 2, 3 and 5. At years 4.3 and 6.3, the difference between the two treatments was statistically significant, favouring the ART/HVGIC restorations. No statistically significant difference was found between the weighted mean survival percentages of ART/HVGIC and traditional treatments in multiple-surface restorations in posterior permanent teeth.Conclusion The ART method using HVGICs can be considered as a replacement for traditional restorations in single- and multiple-surface cavities in primary molars, and in single-surface cavities in posterior permanent teeth, particularly for amalgam.

'There's a Wall There-And That Wall Is Higher from Our Side': Drawing on Qualitative Interviews to Improve Indigenous Australians' Experiences of Dental Health Services

Indigenous Australians experience high levels of untreated dental disease compared to non-Indigenous Australians. We sought to gain insight into barriers that prevent Indigenous Australians from seeking timely and preventive dental care. A qualitative study design was implemented, using face-to-face interviews conducted December 2019 to February 2020. Participants were 20 Indigenous Australians (10 women and 10 men) representing six South Australian Indigenous groups; Ngarrindjeri, Narungga, Kaurna, Ngadjuri, Wiramu, and Adnyamathanha. Age range was middle-aged to elderly. The setting was participants' homes or workplaces. The main outcome measures were barriers and enablers to accessing timely and appropriate dental care. The findings were broadly grouped into eight domains: (1) fear of dentists; (2) confusion regarding availability of dental services; (3) difficulties making dental appointments; (4) waiting times; (5) attitudes and empathy of dental health service staff; (6) cultural friendliness of dental health service space; (7) availability of public transport and parking costs; and (8) ease of access to dental clinic. The findings indicate that many of the barriers to Indigenous people accessing timely and appropriate dental care may be easily remedied. Cultural competency training enables barriers to timely access and provision of dental care to Indigenous Australians to be addressed. The findings provide important context to better enable health providers and policy makers to put in place appropriate measures to improve Indigenous people's oral health, and the Indigenous oral health workforce in Australia.

Patient-reported outcomes associated with different restorative techniques in pediatric dentistry: A systematic review and MTC meta-analysis

BACKGROUND

Despite the increasing number of studies evaluating patient reported outcome measures (PROs), there is no clearness regarding which restorative treatment offers major benefits based on the pediatric patient perspective.

AIM

To compare different restorative techniques in pediatric dentistry regarding patient-reported outcomes.

DESIGN

Literature searching was carried out on prospective studies indexed in PubMed, Scopus and OpenGrey. A Mixed Treatment Comparisons (MTC) meta-analysis was undertaken considering the results from reviewed studies. Anxiety, pain and quality of life were extracted as mean with standard deviation, percentage of pain, and mean difference of scores with standard deviation, respectively. For direct comparisons, data were combined using a random-effect model. Heterogeneity was assessed with the I2 statistic. For indirect comparisons, fixed and random effects were chosen through comparison of competing models based on the Deviance Information Criteria (DIC). The expected efficacy ranking based on the posterior probabilities of all treatment rankings was also calculated.

RESULTS

An initial search resulted in 4,322 articles, of which 17 were finally selected. Due to unavailability of data, only pain, anxiety and oral health related quality of life (OHRQoL) were statistically analyzed. The difference in means (95% CI) of anxiety between treatments using only hand instruments with or without chemomechanical agents were -5.35 (-6.42 to -4.20) and -5.79 (-7.77 to -3.79) respectively when compared to conventional treatment using rotary instruments and/or local anesthesia. Regarding pain, there was a trend for treatments without rotary instruments and local anesthesia to be less frequently reported as painful. No statistical difference was found intragroup nor among treatments for OHRQoL.

CONCLUSIONS

Anxiety and pain are directly related with more invasive restorative treatments. On the other hand, quality of life is not improved regardless of the restorative technique used. Further well-designed prospective studies regarding PROs in children are still necessary.
