Dental Fear and Anxiety of Chinese Preschool Children in a School-Based Outreach Service Using Silver Diamine Fluoride for Caries Control: A Cross-Sectional Study

Risk factors for dental anxiety and cooperativeness in pediatric patients with or without oral habits (bruxism, nail biting, and thumb sucking)

INTRODUCTION

Anxiety and fear can deter patients from visiting dentists and can deteriorate their oral health. In children, this can also affect their cooperativeness. No studies exist on potential links between oral habits and dental fear and children's cooperation. Moreover, predictors of dental anxiety and patient cooperativeness are controversial. Therefore, this study was conducted with the objectives of (1) evaluating associations between oral habits and children's dental fear and cooperativeness as well as (2) potential risk factors of dental anxiety, cooperation, and oral habits.

METHODS

This quasi-experimental study was performed on 169 child patients aged from 4 to 10 years needing dental treatment (82 boys [6.9 ± 1.7 years], 87 girls [6.7 ± 1.7 years]). After a diagnostic visit, patients were treated. Their anxiety and behavior were evaluated through Venham scales. Their cooperativeness was examined using Frankl scale. The following factors were collected: oral habits (bruxism, thumb sucking, and nail biting), children's and parents' demographics and education, history of dental treatment, continuation of the habit, if the parents sought advice to quit the habit, previous treatment history (its type, cooperativeness, pain). The associations between anxiety/cooperativeness with these factors were assessed using chi-square, Spearman correlation coefficient, and multiple linear regressions (α = 0.05).

RESULTS

The average Venham and Frankl scores were 1.45 ± 1.45 and 0.76 ± 0.95, respectively. The multiple linear regression identified the children's cooperation in visiting the previous dentist, the pain experienced during treatment by the previous dentist, and the current treatment type to be associated with both Venham/Frankl scores (P < 0.05). None of the assessed oral habits were found to be associated with the anxiety and cooperativeness of children. Definitive risk factors of children's anxiety and cooperativeness (according to both Venham and Frankl scales) were their previous cooperativeness in the previous dental treatment session, the pain experienced during treatment by the previous dentist, and the type of the treatment administered in the current dental session. The scales were excellently correlated with each other.

CONCLUSIONS

The children's anxiety and cooperativeness are not associated with their evaluated oral habits 'bruxism, nail biting, or thumb sucking'. Risk factors for children's cooperation and anxiety are their previous experiences of pain and previous cooperativeness as well as the current treatment type.

A randomised clinical trial to arrest caries using silver diamine fluoride therapy with two postoperative instructions

OBJECTIVE

The objective of this study is to investigate the beneficial effect of not rinsing for 30 min in arresting early childhood caries after SDF therapy.

METHODS

This randomised clinical trial recruited 3- to 4-year-old kindergarten children with active (soft) dentine caries. A questionnaire was sent to the parents to collect children's demographic data and oral health-related behaviours. A dentist conducted an oral examination and measured the caries experience using dmft index and oral hygiene using visible plaque index. After 38 % SDF therapy, the children were randomly allocated into two groups. Children in group A were instructed to rinse with water immediately, whereas children in group B were asked to refrain from rinsing, drinking, or eating for 30 min. After six months, the same examiner determined the lesion activity (active/arrest) of the SDF-treated carious tooth surface. Generalized Estimating Equations was used to compare the proportion of caries arrest (caries-arrest rate) between the two groups.

RESULTS

This study recruited 298 children with 1,158 decayed tooth surfaces receiving SDF therapy at baseline and evaluated 275 (92 %) children with 1,069 (92 %) SDF-treated tooth-surface at the six-month examination. The demographic background, oral hygiene and caries status of two groups were comparable at baseline (p > 0.05). The caries-arrest rate for group A and group B were 65 % (337/519) and 61 % (338/550), respectively (p = 0.28).

CONCLUSION

This randomised clinical trial found not rinsing for 30 min after SDF therapy is not better than immediate rinsing in arresting early childhood caries.

CLINICAL SIGNIFICANCE

Topical SDF application leaves an unpleasant taste in the mouth, which may affect the acceptance or even rejection of SDF therapy among young children. This study provides clinicians with information to make their decision on postoperative instruction after SDF therapy.

Enhancing patient-provider encounters when proposing SDF therapy by utilizing a qualitative analysis of parental feedback

Purpose

Silver Diamine Fluoride (SDF) is a minimally invasive option for caries arrest, part of a paradigm shift in the management of pediatric dental caries. The perspective of parents regarding the long-term pros and cons of this therapy should be understood in order to achieve optimal patient-centered care.

Methods

This study used Constant comparative analysis as an analytic approach, applying the Precaution-Adoption Process Model (PAPM) as the Grounded Theory framework in the qualitative analysis of 30 parental unformatted, spontaneous comments collected at the end of a questionnaire to evaluate their satisfaction with treatment provided at a University Clinic.

Results

Our analysis provided important insights about the factors that influenced the parents' decision to act and have their child receive SDF therapy, their perception of the outcomes, the necessary follow-ups after the therapy, and what impacted on their overall satisfaction with the completed procedure. Both positive and negative themes were identified. The positive themes point to SDF treatment's ease of application and addressing the immediate treatment needs on children with limited cooperation. The negative themes identified the adverse consequences of SDF treatment, specifically, the duration and appearance of the cosmetic consequences, as well as the parents' misunderstandings and incorrect expectations of the long-term sustainability of the treatment, which in many instances requires further interventions. It was also evident from the parents' comments that they needed additional educational guidance on other aspects of the treatment, such as the necessity for clinical follow-ups, information that impacted parents' overall satisfaction with the treatment their child received.

Conclusion

Our results highlight the need to discuss the short and long term benefits of the treatment, as well as, its short and long-term limitations. Specifically, while it is important to discuss immediate outcomes and consequences, such as the ease of treatment and the resultant staining, to ensure that parental consent for the treatment is truly well-informed, it is also important to prepare parents, when this procedure is initially proposed, of the likely need for additional oral care interventions in the future.

Evaluation of the Caries-Arresting Potential of Silver Diamine Fluoride Gel With Potassium Iodide Versus Sodium Fluoride Varnish: An Observational Study

Introduction Silver diamine fluoride (SDF) with potassium iodide (KI) has emerged as a promising, aesthetic, non-invasive management by limiting the staining caused by SDF. However, no studies are comparing the caries-arresting potential of SDF gel with KI. The study aims to observe and evaluate the caries-arresting potential of SDF gel with KI compared to sodium fluoride (NaF) varnish. Materials and methods The present observational study was conducted with a split-mouth design. A total of 33 participants, in the age group of two to six years, with occlusal caries of the International Caries Detection and Assessment System (ICDAS) I and II involving both right and left upper or lower primary molar teeth, were included. SDF gel with KI and fluoride varnish (FV) was applied to the contralateral teeth on the same arch. Participants were recalled at 3, 6, 9, and 12-month intervals to monitor the progression or arrest of carious lesions. Result At the end of 12 months, 66.7% and 70.5% of the teeth showed arrest of caries with SDF gel with KI and FV, respectively. Intra-group analysis using the Friedman test shows significant differences in both groups across the timeline (p=0.001). Intergroup analysis using the Whitney U test reveals no significant difference in caries-arresting potential between the groups at various timelines (p=0.231). Conclusion There was no significant difference in arresting enamel caries of primary teeth between the use of 5% NaF and 38% SDF with KI. However, there was a significant difference within the group between the 3rd and 12th-month follow-up. Hence, the biannual application is recommended in both FV and SDF with KI.

Postoperative instructions for silver diamine fluoride therapy: A scoping review of current evidence and practice

OBJECTIVES

Silver diamine fluoride (SDF) has gained popularity in dentistry as an anti-hypersensitive and anti-caries agent. This study aims to review the postoperative instructions for SDF therapy and examine the evidence supporting these instructions in treating dentine hypersensitivity and caries control.

DATA AND SOURCES

Two independent reviewers searched three electronic databases (EMBASE, PubMed, and Web of Science) to identify clinical studies that used SDF to treat dentine hypersensitivity and dental caries. Additionally, they searched Google Chrome for information from manufacturers, the department of health, national dental organisations, authoritative dental organisations, and universities regarding SDF therapy for these conditions. Data on postoperative instructions were extracted, and their impact on the treatment of dentine hypersensitivity and caries control was investigated.

STUDY SELECTION

This review included 74 clinical studies, 11 sets of instructions from SDF manufacturers, and six recommendations from national dental organisations, departments of health and universities. Amongst the included records, 50 clinical studies, two manufacturers, and one department of health mentioned postoperative instructions for SDF therapy. The recommendations varied, from suggesting no specific instructions, immediate rinsing, refraining from eating or drinking for 30 to 60 min, and even avoiding brushing until the next day after SDF therapy. Notably, no clinical studies reported the effects of these postoperative instructions on the SDF treatment of dentine hypersensitivity or dental caries.

CONCLUSIONS

This scoping review highlights the presence of inconsistent postoperative instructions for SDF therapy in the treatment of dentine hypersensitivity and caries control. Furthermore, there is a lack of evidence supporting the effectiveness of these instructions.

CLINICAL SIGNIFICANCE

No evidence supports the postoperative instructions for SDF therapy for managing dentine hypersensitivity and dental caries. Studies are necessary to provide guidance for clinicians using SDF in their clinical practice.

Global prevalence of early childhood dental fear and anxiety: A systematic review and meta-analysis

OBJECTIVE

The objective of this review is to determine the global prevalence of dental fear and anxiety (DFA) in early childhood and identify its related factors.

METHODS

The systematic review utilized three common English-language databases (PubMed, EMBASE, and Web of Science). Two independent researchers performed a systematic search to include observational studies on young children published from 2000 to 2023. They extracted information on prevalence of DFA, assessment tools used, study sites, respondents, and children's dental visit experiences.

RESULTS

A total of 2,895 studies were identified, and 25 studies met the inclusion criteria for analysis. The pooled prevalence of DFA among 2- to 6- year-old children was estimated to be 30 % (95 % CI=25, 36). Children without dental visit experience (OR=1.37, 95 % CI=1.18, 1.59) and children with caries experiences (OR=1.18, 95 % CI=1.09, 1.27) had higher odds of experiencing DFA compared to those with dental visit experience or caries-free status. The most commonly used assessment tools in the included studies were the Frankl Behaviour Rating Scale (32 %, 8/25), Children's Fear Survey Schedule-Dental Subscale (20 %, 5/25), and Dental Anxiety Question (20 %, 5/25).

CONCLUSIONS

This systematic review reveals that approximately one-third of young children globally experience DFA. Children who lack dental visit experience or have caries experiences are at increased risk of DFA. Clinicians can use this information to make informed decisions regarding dental care provision for young children.

CLINICAL SIGNIFICANCE

This study provides comprehensive information on the global prevalence of dental fear and anxiety and its associated factors in early childhood. The findings can assist clinicians in understanding and addressing DFA in their dental care approach for young children.

The Caries-Arrest Effectiveness of Silver Diamine Fluoride Treatment with Different Post-Treatment Instructions in Preschool Children: A Study Protocol for a Randomized Controlled Trial

In this 12-month randomized active-controlled clinical trial, we compare two post-treatment instructions for silver diamine fluoride (SDF) therapy in arresting dentine caries. The trial will include at least 254 kindergarten children with active dentine caries. The children will be randomized into two groups and receive a 38% SDF solution applied topically to their carious lesions. Children in Group A will rinse immediately, whereas those in Group B will refrain from rinsing, eating, and drinking for 30 min. One trained examiner will perform the dental examination at baseline and every six months. The primary outcome measurement will be the proportion of caries lesions that become arrested at the 12-month examination. Potential confounding factors and parents' satisfaction with SDF therapy at baseline and after 12 months will be collected using parental questionnaires. This trial will provide evidence-based information for clinical practitioners to give post-treatment instructions for SDF therapy. This study is registered at ClinicalTrial.gov (USA) (registration number: NCT05655286).
