Does the length of dental procedure influence children's behavior during and after treatment? A systematic review and critical appraisal

A cross sectional study on levels of dental anxiety, its influencing factors, and the preferred management techniques among patients in Riyadh, Saudi Arabia

BACKGROUND

Dental anxiety is marked by intense and irrational fear of dental procedures affecting millions of individuals worldwide. The purpose of this study was to investigate the relationship between dental anxiety, its influencing factors, and the preferred management techniques among adults seeking dental care in Riyadh.

METHODS

A cross-sectional questionnaire study was carried out among 1734 patients who visited dental clinics in Riyadh. A self-administered questionnaire was developed and validated, comprising 28 closed-ended questions; it demonstrated good reliability and internal consistency (Cohen's kappa coefficient = 0.90, Cronbach's alpha coefficient = 0.86), it contained pre-validated Modified Dental Anxiety Scale to quantitatively assess the level of dental anxiety. Data analysis involved descriptive analysis, Chi-square test, Pearson correlation coefficient and multiple linear regression.

RESULTS

Majority (59.2%) of participants reported moderate anxiety, while 10.9% experienced high anxiety which was significantly linked to factors such as fear of pain (37.8%) and anaesthetic needles (25.8%). Topical anaesthetic gel (64.5%), pre-treatment explanations (78.9%), and conducive clinic environment (79.4%) were perceived as effective anxiety alleviators. A negative correlation existed between dental anxiety and preferred management techniques. Dental anxiety had significant association between gender (β = 0.910) and age (β = 0.263).

CONCLUSION

This study revealed that majority of participants had moderate dental anxiety, linked significantly to influencing factors like frequency and purpose of dental visits and past dental experiences. The study also found the preferred anxiety management methods among participants which included topical anaesthetic gel, pre-treatment explanations, and a comfortable clinic environment.

Computer-assisted open exposure of palatally impacted canines for orthodontic eruption: A randomized clinical trial

OBJECTIVE

This randomized clinical trial aimed to assess the feasibility of computer-assisted open exposure of palatally impacted canines.

MATERIALS AND METHODS

Patients aged 11-30 years who required orthodontic eruption for the full palatal impaction of their canines were included in this study. Exclusion criteria were psychosocial and dental contraindications of orthodontic treatment, congenital craniofacial disorders, and trauma in the patient's history in the vicinity of the surgical site. Virtual planning software was used to register the intraoral scans and cone-beam computed tomography data and to design a surgical template. In the test group, exposure of the canines was guided by a surgical template, whereas in the control group, the surgeon relied on the surgical plan to localize the impacted canine. The success of the intervention, duration of surgery, and complications, including excessive hemorrhage, damage to the canine or neighboring anatomical landmarks, and postoperative inflammation of the surgical site were assessed. Postoperative pain was reported by the patients using the visual analog pain scale (VAS).

RESULTS

Surgery was deemed successful in all patients in both groups. During healing, no complications were observed. The duration of surgery decreased significantly in the test group (4 min 45.1 s ± 1 min 8.4 s) compared to that in the control group (7 min 22.3 s ± 56.02 s). No statistically significant differences were observed between the VAS scores of the two study groups.

CONCLUSIONS

The application of virtual planning and static navigation is a viable approach for the open exposure of palatally impacted canines.

CLINICAL TRIAL REGISTRATION NUMBER

NCT05909254.

CLINICAL SIGNIFICANCE

Computer-assisted surgery is a feasible method for open exposure of palatally impacted canines, which decreases the duration of surgery compared to the freehand method.

Evaluation of EMLA cream with microneedle patches in palatal anesthesia in children: a randomized controlled clinical trial

Palatal injections are considered to be one of the most painful dental procedures. As a result, it was important to find alternatives to this painful injection to improve children's cooperation. The dental literature mentioned using EMLA cream as a possible alternative to conventional injections, but its anesthetic effect was debated. Therefore, it was valuable to research the impact of microneedle patches to enhance the effectiveness of this cream. The purpose of this randomized controlled clinical trial was to compare the effectiveness of different methods of anesthesia and pain levels in children aged 7-11 years. The study compared the use of EMLA cream, EMLA with microneedles, and conventional palatal injections. A total of 90 children were randomly assigned to three groups: Group 1 received conventional palatal anesthesia (control), Group 2 received EMLA cream only, and Group 3 received EMLA with microneedles. Pain levels were assessed using the FLACC and Wong-Baker scales at three different time points: T1(during anesthesia), T2(on palatal probing), and T3(during extraction). The FLACC scale revealed a significant difference in pain between groups only at T1 (P value = 0.000). It was found that the conventional palatal injection group had a higher pain level than the EMLA cream-only group and the group using microneedle patches with EMLA cream (P value = 0.000). However, the other groups did not show significant differences in pain levels during the anesthesia (P value  = 1.00). Similarly, the Wong-Baker scale also demonstrated a statistically significant difference in pain between groups only at T1 (P value  = 0.000). It was found that the conventional palatal injection group had a higher pain level than the EMLA cream-only group and the group using microneedle patches with EMLA cream (P value  = 0.000). However, the other groups did not show significant differences in pain levels during the anesthesia (P value  = 0.091). The study concludes that both EMLA cream alone and EMLA with microneedles can be used as an alternative to conventional palatal anesthesia for children.

Efficacy and cost analysis of intravenous conscious sedation for long oral surgery procedures

The aim of this study was to determine what is considered a long oral surgery and conduct a cost-effective analysis of sedative agents used for intravenous sedation (IVS) and sedation protocols for such procedures. Pubmed and Google Scholar databases were used to identify human studies employing IVS for extractions and implant-related surgeries, between 2003 and July/2023. Sedation protocols and procedure lengths were documented. Sedative satisfaction, operator satisfaction, and sedation assessment were also recorded. Cost estimation was based on The British National Formulary (BNF). To assess bias, the Cochrane Risk of Bias tools were employed. This review identified 29 randomised control trials (RCT), six cohorts, 14 case-series, and one case-control study. The study defined long procedures with an average duration of 31.33 minutes for extractions and 79.37 minutes for implant-related surgeries. Sedative agents identified were midazolam, dexmedetomidine, propofol, and remimazolam. Cost analysis revealed midazolam as the most cost-effective option (<10 pence per procedure per patient) and propofol the most expensive option (approximately £46.39). Bias analysis indicated varying degrees of bias in the included studies. Due to diverse outcome reporting, a comparative network approach was employed and revealed benefits of using dexmedetomidine, propofol, and remimazolam over midazolam. Midazolam, dexmedetomidine, propofol, and remimazolam demonstrated safety and efficacy as sedative agents for conscious IVS in extended procedures like extractions or implant-related surgeries. While midazolam is the most cost-effective option, dexmedetomidine, propofol, and remimazolam offer subjective and clinical benefits. The relatively higher cost of propofol may impede its widespread use. Dexmedetomidine and remimazolam stand out as closely priced options, necessitating further clinical investigations for comparative efficacy assessment.

Analysis of Pediatric Pulpotomy, Pulpectomy, and Extractions in Primary Teeth Revealed No Significant Association with Subsequent Root Canal Therapy and Extractions in Permanent Teeth: A Retrospective Study

Recent evidence suggests that an ever-growing number of pediatric patients require invasive treatments such as root canal therapy (RCT) in their permanent dentition, albeit with little information about risk factors such as prior invasive treatments of pulpotomy or pulpectomy in their primary dentition. Therefore, the primary objectives of this study were to determine the number of pediatric patients who have had any type of invasive treatment in their primary teeth, to assess their association with any subsequent invasive treatment (root canal therapy, extractions) in their permanent dentition, and to assess these trends over time. This retrospective study utilized summary data from a clinical pediatric patient pool (ages 0-17) over the period of 2013-2022. This analysis revealed that pediatric patients requiring pulpotomies and pulpectomies in primary dentition declined between 2013 (n = 417, n = 156) and 2022 (n = 250, n = 12), while root canal therapy (RCT) in permanent dentition increased six-fold from n = 54 to n = 330. In addition, few (7.8%) patients with RCT had a previous history of pulpotomy or pulpectomy, which suggests that invasive treatments performed in primary dentition have no direct association with the subsequent need for invasive treatments in permanent dentition, although more research is needed to determine the explanations for these observations.

Comparative evaluation of cervical pulpotomy and pulpectomy for primary molars with irreversible pulpitis: a multicentre randomised controlled trial

PURPOSE

The objective of this multicentre randomised controlled trial was to compare the clinical/radiographic outcomes of cervical pulpotomy using calcium-enriched mixture cement (PCEM) and pulpectomy using Metapex (PM) in primary molars with irreversible pulpitis (IP).

METHODS

A total of 134 primary molars from 94 children were randomly assigned to two intervention groups: the PCEM group (n = 74) and the PM group (n = 60). Baseline characteristics including age/gender/molar type/tooth type/jaw were recorded. The primary outcome measures were clinical/radiographic success rates assessed at the first and second follow-up appointments. Secondary outcomes included reasons for clinical/radiographic failures. Multiple logistic regression analysis was performed to determine the impact of various factors on the success rates.

RESULTS

The mean age of the participants in both groups was similar (PCEM group: 5.4 years, PM group: 5.5 years). Gender distribution, molar type, tooth type, jaw, and number of practitioners were comparable between the groups. The clinical success rate at the first follow-up was 98.6% in the PCEM group and 96.4% in the PM group. At the second follow-up, the clinical success rate was 97.1% in the PCEM group and 91.1% in the PM group. The radiographic success rates at the first and second follow-up were 98.6% and 96.4% in the PCEM group and 96.4% and 91.1% in the PM group, respectively. Multiple logistic regression analysis did not reveal any significant association between the success rates and age/gender/molar type/jaw, or treatment groups (P > 0.05).

CONCLUSION

In primary molars with IP, both simple/conservative cervical pulpotomy using calcium-enriched mixture cement and pulpectomy using Metapex demonstrated high clinical/radiographic success rates. No significant differences were observed between the two treatment modalities. These findings suggest that both techniques can be considered effective treatment options for managing primary molars with IP.

Evaluating Glass Ionomer Cement Longevity in the Primary and Permanent Teeth-An Umbrella Review

The aim of this umbrella review was to evaluate the longevity of glass ionomer cement (GIC) as a restorative material for primary and permanent teeth. Research in the literature was conducted in three databases (MedLine/PubMed, Web of Science, and Scopus). The inclusion criteria were: (1) to be a systematic review of clinical trials that (2) evaluated the clinical longevity of GICs as a restorative material in primary and/or permanent teeth; the exclusion criteria were: (1) not being a systematic review of clinical trials; (2) not evaluating longevity/clinical performance of GICs as a restorative material; and (3) studies of dental restorative materials in teeth with enamel alterations, root caries, and non-carious cervical lesions. Twenty-four eligible articles were identified, and 13 were included. The follow-up periods ranged from 6 months to 6 years. Different types of GICs were evaluated in the included studies: resin-modified glass ionomer cement (RMGIC), compomers, and low- and high-viscosity glass ionomer cement. Some studies compared amalgam and composite resins to GICs regarding longevity/clinical performance. Analyzing the AMSTAR-2 results, none of the articles had positive criteria in all the evaluated requisites, and none of the articles had an a priori design. The criteria considered for the analysis of the risk of bias of the included studies were evaluated through the ROBIS tool, and the results of this analysis showed that seven studies had a low risk of bias; three studies had positive results in all criteria except for one criterion of unclear risk; and two studies showed a high risk of bias. GRADE tool was used to determine the quality of evidence; for the degree of recommendations, all studies were classified as Class II, meaning there was still conflicting evidence on the clinical performance/longevity of GICs and their recommendations compared to other materials. The level of evidence was classified as Level B, meaning that the data were obtained from less robust meta-analyses and single randomized clinical trials. To the best of our knowledge, this is the first umbrella review approaching GIC in permanent teeth. GICs are a good choice in both dentitions, but primary dentition presents more evidence, especially regarding the atraumatic restorative treatment (ART) technique. Within the limitation of this study, it is still questionable if GIC is a good restorative material in the medium/long term for permanent and primary dentition. Many of the included studies presented a high risk of bias and low quality. The techniques, type of GIC, type of cavity, and operator experience highly influence clinical performance. Thus, clinical decision-making should be based on the dental practitioner's ability, each case analysis, and the patient's wishes. More evidence is needed to determine which is the best material for definitive restorations in permanent and primary dentition.

Comparison of Oral Health-Related Quality of Life scores in children treated for early childhood caries under general and local anesthesia: a quasi-experimental study

PURPOSE

The purpose of this study was to compare the changes in oral health-related quality of life (OHRQoL) scores in children treated for Early Childhood Caries (ECC) under general (GA) and local anesthesia (LA).

METHODS

A quasi-experimental study was carried out on 73 children, with 37 in the GA group and 36 in the LA group. The early childhood oral health impact scale (ECOHIS) was used to measure OHRQoL, with the type of anesthesia (LA or GA) serving as the explanatory variable. A Friedman test was used to assess the difference between the LA and GA groups at baseline, one-week, and one-month follow-up points.

RESULTS

The results showed a significant difference in the overall mean ECOHIS scores between the LA and GA groups at 1-week (LAmean ± SD = 6.12 ± 1.11, GAmean ± SD = 5.50 ± 0.88; P = 0.01) and 1-month (LAmean ± SD = 5.87 ± 1.12, GAmean ± SD = 4.96 ± 0.99; P < 0.001) follow-up points. Irrespective of the administered anesthesia, a significant (P < 0.001) reduction in the mean score for dental pain was observed at both 1-week (mean ± SD = 1.30 ± 1.16) and 1-month (mean ± SD = 0.81 ± 0.89) timepoints after the treatment, as compared to the baseline assessment (mean ± SD = 2.02 ± 1.02).

CONCLUSION

Early treatment for ECC reduces pain, restore normal activities, and improves the quality of life of affected children. Specifically, GA was found to be more beneficial for both children and parents. However, further studies using more robust study designs and carefully considering related factors are necessary to confirm these findings.

Marginal Integrity of Simplified Adhesive Strategies in Primary Teeth

OBJECTIVE

The aim of this research was to investigate the effect of simplified adhesive strategies (self-etch vs selective enamel etch and 10- vs 20-second adhesive application time) on the marginal integrity in primary molars.

METHODS

Forty deep class-II cavities were prepared in 40 extracted primary molars. The molars were divided into 4 groups based on the applied universal adhesive strategy as follows: groups 1 and 2: selective enamel etch with 20- or 10-second application time and groups 3 and 4: self-etch with 20- or 10-second application time. All cavities were restored with a sculptable bulk-fill composite restoration. The restorations underwent a thermomechanical loading (TML, 5-50 °C, 2-minute dwelling time, ×1000; 400,000 loading cycles, 1.7 Hz, 49 N). Marginal analysis before and after TML was conducted with scanning electron microscopy and the marginal integrity of each restoration was calculated as a percentage of continuous margins. A beta regression model was adopted to statistically analyse the data with a consequent pairwise comparison.

RESULTS

The mean marginal integrity (% ± SD) of the restorations for each tested adhesive strategy after TML was as follows: selective enamel etch/20 seconds = 85.4 ± 3.9, self-etch/20 seconds = 85.3 ± 5.2, self-etch/10 seconds = 80.1 ± 8.2, and selective enamel etch/10 seconds = 80.0 ± 8.5. The difference between both adhesive strategies was not statistically significant at the same application time. The difference between both application times within the same adhesive strategy was statistically significant (P ≤ .01).

CONCLUSIONS

Universal adhesives applied either in selective enamel etch or in self-etch mode result in comparable marginal integrities when restoring class-II cavities in primary molars. Shortened adhesive application time (10 seconds) could lead to a reduction in the marginal integrity in comparison to the recommended application time of 20 seconds.

Preference for Comprehensive Dental Treatment under General Anesthesia among Parents with Previous Experience: A Cross-Sectional Study

This study aims to assess whether parents of children who previously received comprehensive dental treatment under general anesthesia (GA) would prefer comprehensive dental treatment under GA over regular dental care if any of their other children required comprehensive dental treatment. In this cross-sectional study, parents of children who met the inclusion criteria were interviewed by a trained pediatric resident about parental-related factors as well as their satisfaction with their previous GA experience. Also, the factors related to the previously treated child were obtained from dental records. Statistical analysis was carried out, and the p value was set to 0.05. A total number of 306 parents were included. Although most parents, 293 (95.8%), showed satisfaction with the previous GA, 170 (58%) of the satisfied parents preferred regular care. Parents of children who were previously treated under GA for medical-related reasons (p = 0.018), fathers working in a governmental sector (p = 0.021), and families with low-average monthly income (p = 0.017) significantly preferred regular care. In conclusion, most parents were satisfied with the previous GA experience. Family income, fathers' occupation, and medical-related factors can influence parental preference for comprehensive dental treatment under general anesthesia if any of their other children require comprehensive dental treatment.

Comparative Evaluation of Single Rotary File System and Sequential Multi-file Rotary Systems on Time for Biomechanical Preparation and Obturation Quality in Single-visit Pulpectomy Protocol: A Double-blind Randomized Clinical Trial

Background

Single-visit pulpectomy (SVP) protocol with rotary files is highly recommended for the treatment of teeth with irreversible pulpitis. Various rotary endodontic files specially designed for use in the pediatric population are available. The aim is to clinically assess the parameters related to the time required for biomechanical preparation (TBMP) and quality of filling using a single file system vs a sequential multi-file system in infected primary mandibular molars.

Materials and methods

A total of 45 infected primary molars were allocated to three groups (two experimental groups (n = 15) and a control group. The first experimental group was instrumented using NiTi K-Flex files, the second group with a single file rotary system with variably variable (VV) taper, and the third with a sequential multi-file system with constant taper. Biomechanical preparation time was recorded and standardized digital radiograph (RVG) were taken pre- and postinstrumentation. The data recorded was sent for statistical analysis.

Conclusion

There is a substantial reduction of TBMP in primary molars using single file VV taper and multi-sequential file constant taper. Obturation time for all three file systems was comparable and there were no differences between the three file systems used (p > 0.05). Multi-sequential file constant taper files showed a higher probability of optimal obturations and minimal voids followed by NiTi "K-Flex" files and single file system but the difference was nonsignificant (p > 0.05). However, using a rotary in primary teeth results in better canal shape, and less TBMP leading to a better quality of treatment in less time.

Geographic patterns of dental service use in the Child Dental Benefits Schedule: 6 years of claims in the Longitudinal Study of Australian Children

ISSUE ADDRESSED

This article explores the geographic patterns of claims within the Australian Government's Child Dental Benefits Schedule (CDBS).

BACKGROUND

The CDBS is a means-tested schedule implemented in 2014 to improve access to dental services for children. Under the schedule, eligible children receive funding to subsidise dental services.

METHODS

This study used data from the Longitudinal Study of Australian Children and linked data from the Medicare universal healthcare system, to examine dental service use amongst a subset of children aged 10 and 14 years. Dental service items were classified using Two-step Cluster Analysis, and appointments were analysed using multinomial logistic regression. Geographic characteristics were included as predictor variables.

RESULTS

The study found that the majority of dental appointments were non-operative (70.7%, n = 5808), with diagnostic, radiographic, and preventive items being the most common. There were slightly higher proportions of operative appointments (fillings and extractions) compared with non-operative appointments in remote and very remote areas, low socio-economic areas, and Queensland and Northern Territory. Cluster analysis identified eight groups of non-operative appointments and four groups of operative appointments. New South Wales had a higher proportion of 'prophylactic IV' appointments than any other State and Territory, which included debridement and topical fluoride services.

CONCLUSION

Cluster analysis identified distinct groups of non-operative and operative appointments, each with unique characteristics. The distribution of appointments varied by State/Territory and region.

SO WHAT

Further research and interventions are needed to ensure equitable access to services and a shift to preventive care for disadvantaged populations of Australian children. Exploring alternative funding models that support clinically relevant claims, rather than maximising financial benefits such as time-based renumeration models should be explored.

Influence of high-irradiance light curing on the marginal integrity of composite restorations in primary teeth

BACKGROUND

Reducing the necessary time to restore primary teeth improves the cooperation of paediatric patients. This study aimed to investigate the marginal integrity of restorations prepared with a bulk-fill resin-based composite (RBC) containing additional fragmentation chain transfer (AFCT) compared to a conventional RBC when light cured with a rapid high-irradiance (3 s) and a regular (10 s) curing mode.

METHODS

Forty class-II cavities were prepared in 40 primary molars. The molars were randomly divided into four groups based on the applied light-curing modes (regular: 10 s @ 1200 mW/cm2 or high-irradiance: 3 s @ 3000 mW/cm2) and the used restorative material (AFCT-containing bulk-fill RBC "Power Fill" or AFCT-free conventional RBC "Prime"). After thermo-mechanical loading, the marginal integrity was analysed using scanning electron microscopy. A beta regression model and pairwise comparisons were used to statistically analyse the data.

RESULTS

The mean marginal integrity (% ± SD) of the restorations for each group was as follows: Power Fill (10 s: 79.7 ± 15.6) (3 s: 77.6 ± 11.3), Prime (10 s: 69.7 ± 11.1) (3 s: 75.0 ± 9.7). The difference between the RBCs for the same light-curing mode was statistically significant (p ≤ 0.05). The difference between the light-curing modes for the same RBC was not statistically significant (p ˃ 0.5).

CONCLUSIONS

AFCT-containing bulk-fill RBC "Power Fill" achieves similar marginal integrity when light-cured with either high-irradiance or regular light-curing modes. "Power Fill" achieves better marginal integrity than the conventional RBC "Prime" regardless of the applied light-curing mode.

Children's electronic screen time exposure and its relationship to dental anxiety and behavior

Objectives

The purpose of this study was to assess the association between electronic screen time and dental anxiety and behaviour among children aged six to twelve years during dental examination, prophylaxis, and topical fluoride application.

Material and methods

This was a cross-sectional study which included 402 paediatric dental patients aged six to twelve years who came to King Abdulaziz University Dental Hospital in Jeddah, Saudi Arabia. The data was collected from September 2020 to December 2021. Self-constructed questionnaire was used to collect data from the patient and his/her guardian. It was comprised of eight demographic questions as well as 13 multiple-choice questions regarding the patients' screen time. Child dental anxiety was assessed by using Abeer Children Dental Anxiety Scale (ACDAS). Assessment of child's behaviour was done by using Frankl Behavioural Rating Scale.

Results

This study had a response rate of 100%. Out of the 402 participants, 248 (61.7%) were found to have anxiety while 154 (38.3%) were not. Of all participants 274 (68.2%) were cooperative and 128 (31.8%) were not. A Significant relationship between anxiety and behavioural problems during a dental visit and the participant's total exposure hours to electronic devices was found (p < 0.001). Children exposed to electronics at the age of two years or before displayed more anxiety and uncooperative behaviour (p < 0.001).

Conclusions

early exposure to electronic screens, especially for entertainment purposes and longer exposure can be associated with increased dental anxiety and uncooperative behaviour in children age 6-12 years.

Recommendations

Parents should be educated about the risks of permitting their children to use electronic devices and encouraged to replace such devices with activities that incorporate physical activity.

Experience of using a smartphone WeChat applet for dental anxiety assessment and preoperative evaluation: A nationwide multicenter study

Introduction

Dental anxiety is a multivariate phenomenon that regularly occurs during a dental procedure. Although it may lead to patients' safety concerns and adverse events in routine treatment, it is often ignored. The purpose of this research is to develop a novel WeChat Applet for dental anxiety (WADA) with the following features and aims: (1) to help patients with dental anxiety management; (2) provide patient with a physical status self-evaluation; and(3) provide a platform for online assessment and tele-consultancy by dentists. We aimed to test and verify whether such an applet could play a beneficial role before and after a dental procedure and facilitate management of high-risk patients during the COVID-19 pandemic.

Materials and methods

During the 12-month survey period (August 2020 to July 2021), a total of 180 patients aged 3–74 years from eight different cities (n = 180 at the end of treatment, n = 25 for the System Usability Scale (SUS) and follow-up interview) and 20 medical staff from eight different cities (n =20 for follow-up interview) were evaluated by WADA. At the end of the survey period, the results of the interviews were analyzed thematically.

Results

WADA assessment results from 180 patients and follow-up interview results from 45 participants were analyzed. In this study with a male to female ratio of 2:3, 75% were found to be suffering from dental anxiety, 86% were found with postoperative complications, and 11 cases were found to have contraindications to surgery. The total SUS score for WADA is 72.25 above the mean score, proving that WADA is a relevant and useful tool before and after dental treatment. Based on the results of the interviews, the following themes were identified: patient satisfaction; dentists' effectiveness; multi-center data integration; and increase its frequency of usage.

Conclusions

The WADA was developed for dental procedures and is effective for reducing treatment risks, improving patients' satisfaction and dentists' convenience, especially in terms of facilitating management of high-risk patient during the COVID-19 pandemic.

Clinical Effectiveness of Restorative Materials for the Restoration of Carious Primary Teeth: An Umbrella Review

Since untreated dental caries remain a worldwide burden, this umbrella review aimed to assess the quality of evidence on the clinical effectiveness of different restorative materials for the treatment of carious primary teeth. A literature search in electronic bibliographic databases was performed to find systematic reviews with at least two-arm comparisons between restorative materials and a follow-up period ≥12 months. Reviews retrieved were screened; those eligible were selected, and the degree of overlap was calculated using the 'corrected covered area' (CCA). Data were extracted and the risk of bias was assessed using the ROBIS tool. Fourteen systematic reviews with a moderate overlap (6% CCA) were included. All materials studied performed similarly and were equally efficient for the restoration of carious primary teeth. Amalgam and resin composite had the lowest mean failure rate at 24 months while high-viscosity and metal-reinforced glass ionomer cements had the highest. At 36 months, high-viscosity glass ionomer cements showed the highest failure rate with compomer showing the lowest. Most reviews had an unclear risk of bias. Within the limitations of the review, all materials have acceptable mean failure rates and could be recommended for the restoration of carious primary teeth.

The relationship between nitrous oxide sedation and psychosocial factors in the pediatric outpatient setting

BACKGROUND

Moderate sedation using nitrous oxide (N₂ O) has become common in pediatric dentistry. However, less is known regarding the role of patients' characteristics and psychosocial factors in their cooperative behavior during dental procedures with N₂ O.

AIMS

This study aimed to examine pediatric dental patients' behaviors while undergoing N₂ O sedation and to measure the associations between child's cooperative behavior and demographic, physiological responses, and psychosocial factors.

METHODS

In this within-subject observational study, participants received 40% N₂ O/O₂ , by nasal hood, for non-surgical dental procedures. The main outcome measure was the extent of cooperative behaviors, as assessed by the Frankl scale at five timepoints, namely T1: pre-administration of N₂ O, T2: post-administration of N₂ O, T3: dental injection, T4: dental treatment, and T5: post-procedure administration of 100% O₂ . Predictors included age, sex, psychosocial factors reported using the Parenting Style and Dimension Questionnaire and Spence Children Anxiety Scale, as well as pulse rate, respiratory rate, and oxygen saturation. The Wilcoxon signed-rank test and generalized estimation equation were used for data analyses.

RESULTS

In 80 children with a mean age of 7.2 (2.2) years, administration of N₂ O was significantly associated with cooperative behaviors (odds ratio [OR]:2.62, confidence interval [CI]: 1.46-4.70, p = .001) when adjusted for other predictors. There was no interaction between any of the predictors and N₂ O sedation on behaviors. Except for the authoritative parenting style (OR: 1.96, CI: 1.16-3.31, p = .012), which predicted more cooperative behaviors, other predictors were not associated with behavioral outcomes.

CONCLUSION

In children sedated with N₂ O, behavior was independent of the child's demographic and psychosocial factors. While sedated, demographics, vital signs, and anxiety did not contribute to behavior management. However, screening for parenting style may help predict the child's behavioral response.

Analysis of the pattern, type and the extent of dental services provided to children and youth on the territory of Republic of Serbia

Background/Aim: The requirements for dental specialties and the number of specialists in each country are unique and strong indicator of the availability and affordability of primary health care for children and adolescents. The aim of this study was to determine the pattern, type and the extent of dental services, as well as the influence of regional factors and data on whether services are provided by a pediatric dentist or general dentist have effect on these parameters, based on information obtained from dentists providing dental care to children and youth. Material and Methods: Within the project "Program for the improvement of oral health of children and youth in the Republic of Serbia", supported by the Ministry of Health of Serbia, a research was conducted among dentists involved in dental care for children and youth in Serbia. Data collection from primary health care facilities was performed through a specially designed questionnaire. A total of 445 questionnaires were collected from dentists from 102 health centers in Serbia in the period June - October 2019. Results: There are significant differences between regions in the pattern, type and the extent of dental services. In the quantitative analysis, there are no significant differences in the type of dental services between pediatric and preventive dentistry specialists and general dentists. Conclusions: The data from the conducted research speak in favor of a large daily workload of dentists who deliver oral health care for children and youth in Serbia. Additional multifactorial analysis, which includes epidemiological data from the region, but also environmental, demographic and cultural parameters of oral health could be the basis for improving the provision of preventive dental and preventive oral care

Comparative evaluation of efficacy of Physics Forceps versus conventional forceps in pediatric dental extractions: a prospective randomized study

BACKGROUND

This study aimed to determine the efficacy of Physics Forceps in pediatric dental extractions.

METHODS

This was a double-blind, randomized controlled trial with a parallel-arm design and identical allocation ratio (1:1). Children (n=104) were randomly divided into two groups for extraction of mandibular primary teeth (group I: Physics Forceps; group II: conventional forceps). The outcome variables assessed in the study were the time taken for extraction, pre- and postoperative anxiety (using RMS pictorial scale), incidence of fractured teeth, and postoperative pain on the first and third days (using the Wong-Baker faces pain scale).

RESULTS

A significant reduction (P < 0.001) in intraoperative time, anxiety, and incidence of tooth fracture was confined to group I. The pain significantly reduced from the first to the third postoperative day in both groups, but the mean reduction in RMS scores in the physics forceps group was far better than that in the conventional forceps group.

CONCLUSION

Physics Forceps aid in extraction of primary teeth with minimal trauma to supporting structures, as well as reducing anxiety in the pediatric population.

Children and parents perspectives on children's dental treatment under general anesthesia: a narratology from Saskatoon, Canada

Aim

This study aimed to explore the emotional and psychological effects of dental treatment under general anesthesia (DTGA) on children and parents in Saskatoon city, Saskatchewan, Canada.

Design

Semi-structured interviews, video diaries, drawings, and a questionnaire were used to collect data. The study used a narrative perspective and thematic analysis to analyze data.

Results

The findings from children and their parents (N = 25) indicated DTGA is disconcerting from both views. Parental guilt and the desire of both parents and children to not have to go through the experience again fueled at least short-term compliance with brushing, flossing, and changes in dietary habits.

Conclusion

The children participants provided valuable information to augment that gathered from parents. As the study revealed that the DTGA is psychologically and emotionally troubling for both children and their caregivers, it is imperative to explore ways to ease the GA experience. Specific recommendations were provided for optimizing dental and health services for those children and their families.

Evaluation of children's pain expression and behavior using audio visual distraction

Objectives

Dental anxiety distresses children and their families with consequent poor oral health and costly pediatric dental services. Children's behaviors could be modified using a distraction technique for improved dental treatment. The study evaluates the effects of an audio‐visual distraction on children's behaviors and pain expressions during dental treatment.

Material and Methods

One hundred healthy children, between 4 and 6 years of age, were randomly assigned to one of two groups: audio visual distraction (AVD, N = 61) group and control (CTR, N = 39) group. The pre and post pain expression was collected using a faces pain rating scale from the participated children. Children's behavior was evaluated using the Frankl behavior rating scale by the assigned dentist. Data was analyzed using chi‐squared tests and analysis of variance.

Results

The AVD group demonstrated more “definitely positive” behavior (91.8%) compared to the CTR group (35.9%) based on the Frankl scale evaluation from pre‐ and post‐treatment (p < 0.0001). The pain rating scale did not demonstrate a significant difference in post‐treatment pain scales (p = 0.2073) or changes in pain (p = 0.1532) between the AVD group and CTR group.

Conclusions

The AVD is an effective distraction tool for young children during dental treatment regardless of child's subjective pain expression.

Scoping review of trials evaluating adhesive strategies in pediatric dentistry: where do simplified strategies lie?

BACKGROUND

Adhesive restorations allow a conservative approach to caries management and are increasingly used as a restorative option in pediatric dentistry. Placement can be difficult in children because of the cooperation required for multiple bonding steps. Due to this, it is vital to assess if novel, simpler strategies have been featured in clinical trials and if clinical trials are researching the different existing adhesive strategies.

METHODS

This review followed Preferred Reporting Items for Systematic Reviews and Meta-analysis adapted for Scoping Reviews (PRISMA-ScR) guidelines. PubMed/Medline, Cochrane Central, Scopus and EMBASE were used for systematic search, using free keywords and controlled search terms. Clinical trials of children requiring a restorative intervention which featured adhesive strategies were included. Only peer-reviewed trials of primary teeth restored with resin composites, published in the last 10-year period were eligible. Data charting was accomplished independently by two reviewers, and studies were summarized according to their date, type, intervention, sample size, observation period, outcomes and conclusions. Quality assessment was performed using Cochrane's Risk of Bias 2.0 tool.

RESULTS

700 potentially relevant references were found, which after a rigorous inclusion scheme, resulted in a total of 8 eligible clinical trials. Out of these, 7 were randomized clinical trials. Most trials featured a split-mouth design and the observation period ranged from 12 to 36 months. The trials evaluated interventions of two self-adhesive composites, two bulk-fill composites, two novel composites, one compomer and eight adhesives from different strategies. Most studies (4/8) included were judged to raise some concerns regarding risk of bias, while two were classified as high risk and two as low.

CONCLUSION

Few studies comparing adhesive strategies were found, especially adhesives in sound substrates. The existing studies do not reflect all current approaches that could be used in pediatric dentistry. Further studies addressing bioactive composites and contemporary adhesives are necessary.

Oral health status and oral health-related quality of life in children with attention-deficit hyperactivity disorder and oppositional defiant disorder

AIMS

Oral diseases can affect various aspects of life in patients with attention deficit hyperactivity disorder/oppositional defiant disorder (ADHD/ODD). This study aimed to assess the oral health status and oral health-related quality of life (OHRQOL) in ADHD/ODD children.

METHODS

Forty ADHD/ODD and 80 control children aged 3-7 years old were included in the study. Gingival index (GI), dmft score, and the pediatric oral health-related quality of life (POQL) questionnaire were used to determine the oral health status and OHRQOL, respectively.

RESULTS

The mean dmft and GI were significantly higher in the ADHD/ODD group than the control group (P = .002 and P = .001). In the ADHD/ODD children, the total score of OHRQOL and the mean scores of the emotional, physical, role, and social domains were lower than that in the control group (P = .0004, P = .027, P = .002, P = .014, and P = .043, respectively). Poisson's regression showed that there was a significant relationship between OHRQOL and dmft scores (P-value < .001). However, the association between GI and OHRQOL scores was not significant.

CONCLUSION

Higher dmft and GI scores were found in children with ADHD/ODD than the control children. A lower POQL score was detected in ADHD/ODD patients, which translates to a better level of OHRQOL.

Comparison of Clinical and Radiographic Success of Rotary with Manual Instrumentation Techniques in Primary Teeth: A Systematic Review

Aim and objective

A systematic review was planned to compare the clinical and radiographic success rate of pulpectomy in primary molars using a rotary system and hand files system.

Study design

The literature search was undertaken in electronic databases from January 2000 to December 2019 using keywords. Four hundred and forty-two studies were identified after applying limits. Three hundred and thirty-one irrelevant articles were eliminated. Among the 111 articles obtained, 90 articles were eliminated after reading the titles and abstracts. After assessing the full text, 18 articles were eliminated. Randomized controlled trials (RCTs) published in the English language on pulpectomy of primary molars, using hand files and rotary files and with a follow-up period of 12 months were included.

Results

Three RCTs comparing the clinical and radiographic pulpectomy success rates using rotary and hand files instrumentation were finally selected. Qualitative assessment with RoB 2.0 showed one study had a low risk of bias and two studies had a high risk of bias.

Conclusion

Pulpectomy procedures in primary teeth using rotary and hand files instrumentation techniques were equally effective in terms of success rates.

Influence of hand and rotary files for endodontic treatment of primary teeth on immediate outcomes: Secondary analysis of a randomized controlled trial

BACKGROUND

Endodontic treatment of primary teeth can be time-consuming.

AIM

To compare hand and rotary files regarding the time for root canal chemical-mechanical preparation, child's behavior, apical limit of the obturation, and post-operative pain.

DESIGN

This secondary data from a randomized clinical trial with two parallel arms evaluated endodontic instrumentation in 88 children aged 4-9 years. Stratified and block randomization was performed into two groups: K-file hand and ProDesign Logic rotary files. The evaluated outcomes were the chemical-mechanical preparation time, child's behavior using the Frankl scale, apical limit of the obturation, and post-operative pain using the Faces Pain Scale-Revised. One operator and all outcome appraisers were blinded to the chemical-mechanical technique. Multiple linear regression, chi-square, and Fisher's exact test were performed.

RESULTS

The mean time for chemical-mechanical preparation using hand files was 24.5 (SD 4.0) minutes, and using rotary files, it was 17.0 (SD 2.5) minutes (P < .001). No difference was found between the instrumentation methods in the child's behavior, apical limit of the obturation, or post-operative pain.

CONCLUSIONS

The ProDesign Logic file reduced the average procedure time but presented no difference in the other variables studied when compared to the K-file.

Children's Pain Perception and Behavioral Feedback during Local Anesthetic Injection with Four Injection Site Preparation Methods

Introduction:An effective pain control significantly contributes to an optimal dental treatment in pediatric dentistry. This study was conducted to compare children's pain perception and behavioral feedback during local anesthetic injection accompanied with counter-irritation, refrigerant, ice precooling or topical benzocaine. Methods:This study was conducted on 99 children who needed dental treatment in bilateral maxillary primary molars by local anesthesia. Subjects were randomly assigned to three groups, in which the injection site was prepared using counter-irritation in group I, ice precooling in group II, and refrigerant spray precooling in group III. In all three groups, 20% benzocaine gel was used in the injection site of opposite quadrant as a control. The perceived pain and behavioral feedback of children during injection were evaluated using the visual analogue scale (VAS) and sound, eye, and motor (SEM) indexes. Sign and Kruskal-Wallis tests were used to analyze data at a significance level of P < 0.05. Results:The perceived pain was significantly lower when using benzocaine compared to the other three methods (P < 0.05). Behavioral feedback of children when using benzocaine was not significantly different from the counter-irritation method (P=1.00). However, behavioral feedback with counter-irritation was significantly better than precooling (P < 0.05). Counter-irritation was significantly more effective than precooling methods in reduction of pain perception and improvement of behavioral feedback (P < 0.05). Conclusions:The perceived pain was significantly lower when the benzocaine method was used. Behavioral feedback was significantly better with benzocaine and counter-irritation methods compared to precooling procedures.

Anxiolysis in the Surgical Management of a Compound Odontoma in a Pediatric Patient

Among odontogenic tumors, odontoma is the most frequent. The common treatment contemplates a conservative approach. While this procedure is generally accepted and tolerated, some difficulties may be encountered in the case of pediatric patients. Indeed, negative feelings of tension, apprehension, nervousness, and fear are likely to occur. The present report is aimed at discussing the management of a compound odontoma in a pediatric patient under anxiolysis with diazepam on an outpatient basis. The surgery was carried out without complications, and the discharge was completed safely. Oral premedication with diazepam should be considered to avoid more invasive sedation procedures in anxious pediatric patients.
