Oral health-related quality of life in children with celiac disease.

PURPOSE: There is limited knowledge about oral health-related quality of life (OHRQoL) in children with celiac disease (CD). This study aimed to assess OHRQoL in children with CD compared to healthy controls. METHODS: This case-control study included children with CD and healthy controls. Three scales were used to assess OHRQoL in different age groups: 6-7 years, 8-10 years, and 11-14 years. The OHRQoL scores were compared between cases and controls to examine the possible associations between OHRQoL and demographics, socioeconomic status, and oral health. RESULTS: Overall, 104 children with CD and 104 healthy children (controls) were included. The mean age was 10.67 ± 2.39 years in CD patients and 10.69 ± 2.36 in controls (P = 0.971). Male and female children constituted 50% of each group. Children with CD had significantly higher OHRQoL scores than controls (P = 0.003). Low education levels of parents of children with CD and a higher number of siblings in controls were associated with high OHRQoL scores (P = 0.002, P < 0.020, and P = 0.010, respectively). Recurrent aphthous stomatitis (RAS) increased the OHRQoL scores by 7.5 on average (P = 0.016). CONCLUSION: Children with CD had poor OHRQoL compared with healthy controls. Poor OHRQoL in children with CD was associated with RAS and with lower parental income and education. RAS was an independent predictor of poor OHRQoL in children with CD.

Oral and dental manifestations of celiac disease in children: a case-control study.

BACKGROUND: Celiac disease (CD) is an immune-mediated enteropathy. CD may also involve complications with the oral cavity, which can result in various dental and oral pathologies. There are currently a limited number of studies on the oral manifestation of CD. This study aims to compare the oral manifestations of children with CD against healthy controls in Saudi Arabia. MATERIALS AND METHODS: This study includes 208 children aged 6-14 years, distributed equally into CD patients and healthy controls. A parent completed and validated the interview questionnaire, which included the child's personal information and medical history. A dental examination was undertaken to measure possible recurrent aphthous stomatitis (RAS), dental enamel defects (DEDs), dental caries experience, and dental malocclusion. Data were analyzed using descriptive statistics and bivariate and multivariate analysis. RESULTS: Two hundred and eight participants were included (104 CD patients and 104 controls). The mean age for CD patients was 10.67 ± 2.39 years and 10.69 ± 2.36 for the healthy controls. CD children had more RAS than controls (42.3% vs. 15.4%, P < 0.001) (OR = 4.03, 95% CI = 2.09-7.81) and more DEDs than healthy controls (70.2% vs. 34.6%, P < 0.001) (OR = 4.45, 95% CI = 2.48-7.97). No significant difference was found in the frequency of malocclusion between cases and controls. CONCLUSION: Saudi Arabian children with CD had a greater number of clinical findings of RAS and DEDs than healthy controls. Pediatric dentists should consider the possibility of CD in child patients presenting with RAS or DEDs.

Validity and reliability of the Arabic version of the child perceptions questionnaire for 8-10-year-old children.

PURPOSE: To develop an Arabic version of the CPQ8-10 and test its validity and reliability for use among Arabic-speaking children. METHODS: The 25-item professionally translated questionnaire included two global rating questions across four domains, which was assessed through a pilot study on 20 participants who were not included in the main study. Children (n = 175) aged 8-10 years were consecutively recruited: group I (n = 120) included pediatric dental patients, group II (n = 25) included children with orofacial clefts, and group III (n = 30) included orthodontic patients. Construct (convergent and discriminant) validity, internal consistency, and test-retest reliability were assessed using Spearman's rank correlation coefficients, Cronbach's alpha coefficient, and intraclass correlation coefficient, respectively. All children were clinically examined; 66 children completed the questionnaire a second time. A cross-sectional study design was employed. RESULTS: CPQ8-10 scores and global ratings were positively correlated. CPQ8-10 scores were highest in group II, followed by groups I and III, respectively. CPQ8-10 scores were significantly higher in children affected with caries or malocclusion compared to unaffected children. Cronbach's alpha was 0.95 and the intraclass correlation coefficient was 0.97. CONCLUSIONS: The Arabic CPQ8-10 was valid and reliable; therefore, it can be utilized with Arabic-speaking children in this age group.

Dental maturity in children with celiac disease: a case-control study.

BACKGROUND: Celiac disease (CD) is an immune-related enteropathy triggered by gluten ingestion in susceptible individuals. Oral manifestations of CD have been frequently described, although reports on dental maturity (DM) are scant. Thus, the aim of this study is to assess the prevalence of DM in CD patients and to test for possible predictors. METHODS: This is a case-control study of children with CD and healthy controls between 2017 and 2020. A panoramic radiograph and comprehensive oral examination were performed for each participant. Dental age (DA) was measured according to Demirjian's method and DM was calculated by subtracting the chronological age (CA) from the DA. Statistical analysis was performed to compare the DM between CD patients and controls, and a multivariate analysis was utilized to look for predictors of DM. RESULTS: Two-hundred and eight participants (104 children with CD, and 104 healthy controls) were incorporated. The mean age for CD patients was 10.67 ± 2.40 years, and 10.69 ± 2.37 years for healthy controls (P = 0.971). CD patients had a higher prevalence of delayed DM than controls (62.5% vs. 3%, respectively). They also had a greater delay in DM than controls (- 7.94 ± 10.94 vs. 6.99 ± 8.77, P < 0.001). A multivariate analysis identified age between 6 and 7 years (ß ± SE = 16.21 ± 2.58, P < 0.001), as the only predictor for DM. CONCLUSIONS: CD patients had a greater prevalence of delayed DM than controls. No predictors for DM could be found, except young age.

Effects of Familial Characteristics on Dental Fear: A Cross-sectional Study.

AIM: Dental fear (DF) in children is a multifactorial problem that may affect the child's dental treatment and behavior at the dental office. This study aimed to evaluate the familial characteristics affecting DF among Arabic-speaking 12- to 15-year-old children in Jeddah, Saudi Arabia. MATERIALS AND METHODS: A cross-sectional study assessing 16 middle schools in Jeddah, Saudi Arabia, was performed through multistage stratified random sampling. DF among children was measured using the children fear survey schedule-dental subscale (CFSS-DS) questionnaire. A parental questionnaire was used to collect information regarding familial socioeconomic status, parental DF, and DF among siblings and friends. The data were analyzed using the t test, one-way analysis of variance (ANOVA), and multiple linear regression analysis. RESULTS: A total of 1,522 children were included. Socioeconomic variables were not associated with DF among children. Parental DF, parental dental experiences, siblings' DF, and friends' DF were significantly associated with DF in children. In the regression analysis, mothers' anxiety at the last dental visit, siblings' DF, and friends' DF were significant predictors of DF among children. CONCLUSION: DF in children is associated with mothers' anxiety during their last dental visit and DF in siblings or friends. CLINICAL SIGNIFICANCE: Obtaining comprehensive dental, family, and social history from patients is as essential as asking about medical history for pediatric dentists to plan the most appropriate and effective behavioral management techniques for their pediatric patients. Understanding the etiology of DF assists clinicians to provide better oral health services for their fearful patients.

Responsiveness of the Arabic version of the ECOHIS to dental rehabilitation under general anaesthesia.

BACKGROUND: The Arabic version of the Early Childhood Oral Health Impact Scale (A-ECOHIS) has been validated, but its ability to detect change was not tested. AIM: To evaluate the responsiveness of the A-ECOHIS to dental rehabilitation under general anaesthesia (DRGA). DESIGN: A consecutive sample of 131 parents of children aged 6 years or younger, scheduled for DRGA were recruited from three public hospitals. The parents completed the A-ECOHIS before and 4 weeks following DRGA. The responsiveness of the A-ECOHIS was assessed by evaluating changes in scores before and after DRGA, and by measuring the change in scores in relation to the global question. RESULTS: The A-ECOHIS scores were higher among parents who reported poor oral health on the global question than those reporting better oral health (P = 0.001). There was a significant reduction in the scores at follow-up (P < 0.001). The effect size was 1.5 for the total scale, and 1.3 and 1.6 for the child and family impacts, respectively. After DRGA, the child and family impact section scores decreased by 78.6% and 77.9%, respectively. The majority of parents reported improvement in children's overall oral health-related quality of life post-operatively (94%). CONCLUSION: The A-ECOHIS was responsive to DRGA.

Influence of povidone-iodine on micro-tensile bonding strength to dentin under simulated pulpal pressure.

BACKGROUND: Previous studies had reported that bond strength deteriorate over time following the dentin surface pretreatment with chlorhexidine. Therefore, further investigations are needed to evaluate the effect of other materials such as povidone iodine. The purpose of this study was to investigate the effects of 10% povidone-iodine pretreatment on the resin-dentin micro-tensile bond strength of a single bond adhesive system in permanent teeth over time, and compare it with 2% chlorhexidine. METHODS: Flat dentin surfaces were prepared in 63 extracted permanent teeth. Teeth were randomly assigned to a 10% povidone-iodine pretreatment, a 2% chlorhexidine pretreatment, or a control group. Composite resin blocks were built up over treated surfaces under pulp pressure simulation. The prepared specimens were assigned to three storage time, 24 h, 1 week, and 2 months. Samples were vertically sectioned to obtain specimens of 0.7 to 1.2 mm2 cross-sectional area. RESULTS: No significant reduction of bond strength of povidone iodine group was found among the three storage times (p = 0.477). A significant reduction of bond strength for both chlorhexidine and control groups was found in the three storage times (p <  0.001). CONCLUSION: Povidone iodine pretreatment of etched dentin was effective in reducing the loss of bond strength over time, while the chlorhexidine pretreatment and negative control showed significant deterioration in micro-tensile bond strength over time in permanent teeth.

Characterization of the apical bridge barrier formed following amelogenin apexification.

BACKGROUND: Recombinant amelogenin protein (RAP) is reported to induce complete root apex formation in dog model when used as apexification therapy. It also induces pulp regeneration in 85% of the treated group. Thus, the aim of this study was to investigate the nature of the remaining regenerated calcified tissues of the RAP group that showed no pulp regeneration compared to the calcium hydroxide treated group (CH). METHODS: A total of 240 dogs' open apex root canals were used, after establishment of canals contamination. Canals were cleaned, irrigated, and filled with RAP as an apexification material and compared with CH. Treated teeth were assessed by H&E, trichrome staining, and/or immunohistochemistry technique, at 1, 3, and 6 months. RESULTS: A time-dependent increase in the calcified tissue barrier was observed in the apex of the RAP-treated group compared to the CH-treated group. The newly formed dentin in this RAP group was mainly tubular dentin and was functionally attached to the bone by periodontal ligament, while the CH group showed dentin-associated mineralized tissue (DAMT) associated with the newly formed apical barrier. CONCLUSIONS: Out results suggest that RAP can be used as novel apexification material, resulting in a thickening and strengthening of the canal walls, and achieving apical closure.

Effects of child characteristics and dental history on dental fear: cross-sectional study.

BACKGROUND: Dental fear (DF) is a challenging problem in dentistry. It is multifactorial in origin and many contributing factors have been identified. The aim of the study was to assess dental fear among 12-15 years old Arabic speaking children in Jeddah, Saudi Arabia and its relation to demographic variables, previous dental experience, and child behaviour. METHODS: In this cross-sectional study, a total of 1522 boys and girls from middle schools in Jeddah, Saudi Arabia participated in this study during the period of 2014 to 2016. The Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) was used to assess DF. A parental questionnaire was used to record the children's previous dental experience. Children were examined for caries and the children's behaviour was assessed during dental examination using Frankl Behaviour Rating Scale. The associations between different variables and the CFSS-DS scores were analysed using t-tests, ANOVA, and multiple linear regression analysis. RESULTS: The response rate of the questionnaires was 78.6%. The mean CFSS-DS score was 25.99 ± 9.3 out of a maximum of 75. Bivariate analysis showed that younger children, girls, and public-school students were significantly more fearful than older children, boys, and private school children, respectively (P < 0.001). Children who showed poor behaviour during dental examination were significantly more fearful than those with good behaviour (P < 0.001). Regression analysis showed that children who had significantly higher scores of dental fear were the children who did not visit the dentist in the past year due to dental fear; who never visited the dentist or those who only visited the dentist on pain; who were reported by parents as crying, screaming, or resistant during their previous dental visit; and those who were described to be in pain during previous dental treatment. Dental caries showed no significant association with DF. CONCLUSIONS: This study confirms that DF is low among 12-15 years old Arabic speaking children in Jeddah, Saudi Arabia. DF is associated with age, gender, school type, irregular patterns of dental visits, painful experiences during previous dental visits and negative behaviours during dental examinations.

Consequences of early extraction of compromised first permanent molar: a systematic review.

BACKGROUND: The aim of this study was to systematically review the literature to determine the sequelae of early extraction of compromised first permanent molars (FPMs) with regard to the skeletal and dental development of 5- to 15-year-old children. Meta-analysis was conducted when applicable. METHODS: Our research protocol included a search strategy, inclusion/exclusion criteria, and a data extraction plan. The search engines used were PubMed, Scopus, and Science Direct. Study selection was performed independently by three reviewers. Articles published from 1960 to 2017 were reviewed based on inclusion and exclusion criteria. Meta-analysis was performed to compare space closure between upper and lower arches. RESULTS: Eleven studies fulfilled the inclusion criteria. The consequences were decrease in post extraction space, accelerated development and eruption of second permanents molars (SPMs) and third molars, a decrease in caries and/or fillings on the proximal surfaces of adjacent teeth, lingual tipping and retrusion of incisors, and counter clockwise rotation of the occlusal plane. CONCLUSION: There were several consequences of early extraction of FPMs, which were related to skeletal and dental development. Our systematic review suggests that comprehensive evaluation of the compromised FPMs should be performed before planning an extraction. The ideal time for FPM extraction is when the SPM is at the early bifurcation stage in order to achieve complete closure of the extraction space by the SPM. Benefits should be weighed over the risks to decrease the risk of unfavorable outcomes as much as possible. However, due to the limited evidence on the outcomes and variables that influence them, high-quality prospective studies are needed.

Impact of Dental Rehabilitation on Oral Health-related Quality-of-life in Healthy Children and Those with Special Health Care Needs.

Aim: The aim of this study is to compare the effect of dental rehabilitation on oral health-related quality-of-life (OHRQoL) in children with special health care needs (CSHCN) and healthy children. Materials and methods: The prospective study's sample consisted of 213 parents of caries-affected children, who were aged 6 years or younger and were scheduled for dental rehabilitation under general anesthesia (DRGA). The parent-child dyads were recruited from three public hospitals in Jeddah between October 2014 and May 2016. They comprised healthy children (n = 133) and CSHCN (n = 80). Parents self-completed the early childhood oral health impact scale (ECOHIS) before and 1 month after DRGA. The parents also rated the overall oral health status of their children by answering a global question before and after DRGA. Results: At baseline, the CSHCN had significantly worse OHRQoL in most of the scale domains at 25.9 [standard deviation (SD) 11.3] and 19.9 (SD 10.3) respectively. The OHRQoL significantly improved in both groups postoperatively (p = 0.005, Wilcoxon rank-sum test). The effect size of the improvement in the CSHCN group (+1.8) was greater than that in the healthy group (+1.5) in all domains, except for the family impact and parental distress sections. Conclusion: The DRGA markedly improves OHRQoL in children aged 6 years or younger, and the improvement is even greater in CSHCN. Clinical significance: The substantial improvement in OHRQoL after DRGA highlights the importance of oral health care in young children, which should receive higher priority than it has been done to date. Keywords: Children with special health care needs, Dental caries, Early childhood oral health impact scale, General anesthesia, Oral health-related quality-of-life.

Do children's previous dental experience and fear affect their perceived oral health-related quality of life (OHRQoL)?

BACKGROUND: Oral health-related quality of life (OHRQoL) has been used to describe the consequences of oral health conditions and treatments in children. A better understanding of OHRQoL and its relationship with dental fear and previous dental experience is necessary to improve children's oral health status. The aim of this study was to investigate the association of dental history and experience with dental fear and the OHRQoL of children aged 11 to 14 years. METHODS: A cross-sectional study was conducted using a multi-stage stratified sample of 1,312 middle school children. Information regarding OHRQoL was collected from the children using the Child Perceptions Questionnaire (CPQ11-14), and information regarding dental fear was collected using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Information on past dental experiences and sociodemographic data were collected from the parents using self-administered questionnaires. Dental examinations were performed to assess caries experience. RESULTS: The multivariable model indicated that dental fear was the strongest predictor of OHRQoL as the fearful children had on average CPQ11-14 scores that were 10 units higher than those of the non-fearful children. Regarding past dental experience, pain as the reason for the most recent dental visit was associated with poor OHRQoL, while receiving a filling during the previous dental visits was significantly associated with better OHRQoL. In addition, a larger number of siblings, a lower family income, a lower paternal education level, health problems and prior hospitalization were significantly associated with poor OHRQoL. CONCLUSION: This study identified that dental fear and some factors related to previous dental experience are associated with OHRQoL. In dental practice, children with dental fear should be identified, guided and treated early to avoid deterioration of their OHRQoL.

Validation of the Arabic Version of the Early Childhood Oral Health Impact Scale (ECOHIS).

BACKGROUND: Assessment of the adverse effects of oral health problems on oral health-related quality of life (OHRQoL) is essential to ensure the well-being of children. The Early Childhood Oral Health Impact Scale (ECOHIS) is an instrument that was designed to assess caregivers' perceptions of OHRQoL in preschool children. Although it has been translated into many languages, it has yet to be validated in Arabic. Therefore, this study aimed to translate this questionnaire to Arabic (A-ECOHIS) and test its psychometric properties. METHODS: Questionnaire responses from three samples of caregivers of preschool children ≤ 6 years of age were collected: (i) community-based (n = 422), from preschools selected as a stratified random sample; (ii) clinic-based, from those seeking pediatric dental care at a university clinic (n = 246); and (iii) a test-retest sample (n = 68), a clinic-based group of caregivers who completed questionnaires twice about siblings who were not receiving dental care. Children received a dental examination to assess their decayed, missed, filled teeth (dmft) scores. Convergent validity was evaluated by assessing the A-ECOHIS scores in relation to the response to a global question. Discriminant validity was evaluated by comparing the scores of children with varying levels of oral disease. Internal consistency was assessed by calculating Cronbach's alpha, and the test-retest reliability was assessed using intra-class correlation coefficients (ICCs). RESULTS: The A-ECOHIS scores of the questionnaire sections and the global oral health rating were significantly correlated; Spearman correlation coefficients were, r = 0.55, P ≤ 0.01 (overall score), r = 0.54, P ≤ 0.01 (child section), and r = 0.51, P ≤ 0.01 (family section). The mean A-ECOHIS scores were also statistically significantly higher in children with higher dmft scores compared with lower dmft, and in the clinic-based sample compared with the community sample. The Cronbach's alpha value of the the child, family sections and overall questionnaire were, 0.80, 0.78, and 0.85, respectively. The intra-class correlation coefficient (ICC) of A-ECOHIS was 0.86. CONCLUSION: The A-ECOHIS performed well on all psychometric tests to which it was applied. Thus, it is a valid and reliable instrument that can be used in Arabic-speaking caregivers of preschoolers aged 2 to 6 years.

Reliability and validity of the Children's Fear Survey Schedule-Dental Subscale for Arabic-speaking children: a cross-sectional study.

BACKGROUND: Early recognition of dental fear is essential for the effective delivery of dental care. This study aimed to test the reliability and validity of the Arabic version of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). METHODS: A school-based sample of 1546 children was randomly recruited. The Arabic version of the CFSS-DS was completed by children during class time. The scale was tested for internal consistency and test-retest reliability. To test criterion validity, children's behavior was assessed using the Frankl scale during dental examination, and results were compared with children's CFSS-DS scores. To test the scale's construct validity, scores on "fear of going to the dentist soon" were correlated with CFSS-DS scores. Factor analysis was also used. RESULTS: The Arabic version of the CFSS-DS showed high reliability regarding both test-retest reliability (intraclass correlation = 0.83, p < 0.001) and internal consistency (Cronbach's α = 0.88). It showed good criterion validity: children with negative behavior had significantly higher fear scores (t = 13.67, p < 0.001). It also showed moderate construct validity (Spearman's rho correlation, r = 0.53, p < 0.001). Factor analysis identified the following factors: "fear of invasive dental procedures," "fear of less invasive dental procedures" and "fear of strangers." CONCLUSION: The Arabic version of the CFSS-DS is a reliable and valid measure of dental fear in Arabic-speaking children. Pediatric dentists and researchers may use this validated version of the CFSS-DS to measure dental fear in Arabic-speaking children.

Characteristics of dental fear among Arabic-speaking children: a descriptive study.

BACKGROUND: Dental fear has not only been linked to poor dental health in children but also persists across the lifespan, if unaddressed, and can continue to affect oral, systemic, and psychological health. The aim of this study was to assess the factor structure of the Arabic version of the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS), and to assess the difference in factor structure between boys and girls. METHODS: Participants were 220 consecutive paediatric dental patients 6-12 years old seeking dental care at the Faculty of Dentistry, King Abdulaziz University, Saudi Arabia. Participants completed the 15-item Arabic version of the CFSS-DS questionnaire at the end of the visit. Internal consistency was assessed using Cronbach's alpha. Factor analysis (principal components, varimax rotation) was employed to assess the factor structure of the scale. RESULTS: The Cronbach's alpha was 0.86. Four factors with eigenvalues above 1.00 were identified, which collectively explained 64.45% of the variance. These factors were as follows: Factor 1, 'fear of usual dental procedures' consisted of 8 items such as 'drilling' and 'having to open the mouth', Factor 2, 'fear of health care personnel and injections' consisted of three items, Factor 3, 'fear of strangers', consisted of 2 items. Factor 4, 'fear of general medical aspects of treatment', consisted of 2 items. Notably, four factors of dental fear were found in girls, while five were found in boys. CONCLUSIONS: Four factors of different strength pertaining to dental fear were identified in Arabic-speaking children, indicating a simple structure. Most items loaded high on the factor related to fear of usual dental procedures. The fear-provoking aspects of dental procedures differed in boys and girls. Use of the scale may enable dentists to determine the item/s of dental treatment that a given child finds most fear-provoking and guide the child's behaviour accordingly.

Aggregatibacter actinomycetemcomitans in Down's syndrome children.

OBJECTIVES: To investigate the presence of Aggregatibacter actinomycetemcomitans (Aa) in Down's syndrome (DS) children in comparison with age-matched normal children and to determine if Aa was acquired during childhood in DS individuals. STUDY DESIGN: 60 DS children and 60 healthy children participated in this cross-sectional study. Both groups were matched regarding gender and age and were equally selected from public schools/non-fee paying centers and private schools. Subgingival plaque sample were obtained and analyzed for Aggregatibacter actinomycetemcomitans (Aa). Traditional cultivation method was used on a selective medium "modified malachite green vancomycin agar " RESULTS: A significantly higher percentage ofDS children had Aa in their subgingival plaque compared to their healthy counterparts (Chi square = 8.78, p = 0.003). Although Aa was acquired by children as early as 5 years of age in both groups, no association was found between the occurrence of Aa and age. CONCLUSIONS: Higher proportion ofDS children acquired Aa compared to their healthy controls and Aa is acquired by children as early as 5 years of age.

Sustainability of Improvement in Oral Health-Related Quality of Life in Children After Dental Treatment.

PURPOSE: Dental treatment has been associated with improvement in the oral health-related quality of life (OHRQoL) in children. There is little evidence of whether the effect of treatment is sustainable over time or not. The aim of this study was to determine whether the effect of dental treatment on OHRQoL is maintained or diminishes over time. MATERIALS AND METHODS: A consecutive sample of parents of 47 children between 2 and 6 years who received comprehensive dental treatment at a postgraduate dental clinic were recruited. Parents completed the Early Childhood Oral Health Impact Scale (ECOHIS) prior to treatment and at 1 and 4 months after treatment. Parents were also asked three global questions. Score changes (overall and for each section) between time points were analyzed by a repeated-measures analysis of variance and Bonferroni tests. RESULTS: The children's mean age was 4.7 ± 1.1, and 60% were females. ECOHIS scores were significantly improved from baseline (22.2 ± 6.9) to 1 month after treatment (8.7 ± 6.8) and were further improved at 4 months after treatment (1.9 ± 2.7), P < 0.001, with large effect sizes (2.8 for the child impact section and 2.2 for the family impact section). Parents' perception of changes in the OHRQoL of their children obtained from a global question indicated an improvement in OHRQoL that was sustained over the follow-up period; at 1-month and 4-month follow-up, 89% and 94% of mothers reported that their child's oral health improved a lot after dental treatment, respectively. CONCLUSION: The impact of dental treatment on OHRQoL continued to remarkably improve during the 4 months following dental treatment.

Hall Technique for Carious Primary Molars: A Review of the Literature.

The high frequency of caries in primary teeth and its inadequate treatment are major public health problems during childhood. Nowadays, the Hall technique is one of the methods used for biological sealing in carious lesions in primary molars. Thus, the bacteria will be sealed from oral environment and the caries will be inactive. The objective of this article was to provide an updated search on the Hall technique description, indication, contraindication, advantages, concerns, success and failure, cost-effectiveness, acceptability, and preference in pediatric dentistry, and to compare the Hall technique with traditional crown preparation and conventional treatment options for carious primary molars. A discussion of the recently published articles on the Hall technique reveals that the Hall technique is considered a promising restorative option with high acceptability and longevity; with low failure rate for managing carious primary molars compared to conventional treatment modalities used in primary care settings. Furthermore, the survival rate of stainless steel crowns (SSCs) is considered high, whether provided using Hall technique or traditional preparation by a pediatric dentist. Thus, the Hall technique can be an effective addition to the clinician's range of treatment options for carious primary molars. However, it should be chosen in restricted cases.

Reliability and Validity of the Arabic Version of a Questionnaire Assessing Pain, Discomfort and Related Jaw Function Impairment after Extraction of Primary Teeth in Children.

This study aims to translate a previously published English language questionnaire that assessed pain and discomfort after the extraction of primary teeth in children into Arabic, and evaluate its validity and reliability. All participating children (n = 120), aged 9 to 12-years-old, completed the 33-item Arabic version questionnaire after the extraction procedure had taken place. The questionnaire included three parts that were completed at three different times, namely, immediately, the first evening, and one week after the extraction procedure. Internal consistency, content validity, criterion validity, and factor analysis were performed. The results showed a good internal consistency (Cronbach's alpha = 0.83), acceptable criterion validity with a significantly strong correlation with the Visual Analog Scale (VAS), and satisfactory content validity (average content validity index (CVI = 0.90). The final factor model was comprised of four factors with an eigenvalue greater than 1, explaining 70% of the common variance. The identified factors were labeled as follows: Factor 1-analgesic consumption; Factor 2-expression of discomfort from the extraction site; Factor 3-perception of masticatory capability; and Factor 4-pain/discomfort from the dental extraction procedure. Based on the results, a shorter form of the questionnaire had satisfactory psychometric characteristics and can be used with children within the selected age group.

Myofunctional Trainer versus Twin Block in Developing Class II Division I Malocclusion: A Randomized Comparative Clinical Trial.

This study aimed to evaluate and compare the dentoalveolar effects of the myofunctional trainer T4KTM versus twin block in children with class II division I malocclusion. Two parallel arm randomized comparative clinical trial was conducted, including twenty healthy children, 9-12 years old, showing Angle's class II division I malocclusion due to mandibular retrusion. Children were randomly assigned into two groups according to the appliance used; Group 1: T4k, and Group II: twin block. Follow-up was done every 4 weeks for 9 months. Postoperative cephalometric X ray, study casts and photographs were taken for measurements and comparison. T4K showed a statistically significant reduction in the overjet (-2.50 ± 1.00 mm) (p < 0.0001), and a significant increase in the lower arch perimeter (LAP) (1.19 ± 0.96 mm) (p = 0.01). The twin block showed a statistically significant reduction in the overjet (-3.75 ± 1.10 mm) (p < 0.0001), a significant reduction in the overbite (-16.22 ± 17.02 %) (p = 0.03), and a significant increase in the LAP (1.69 ± 0.70 mm) (p < 0.0001). The overjet showed a higher significant decrease in the twin block group than in T4K (p = 0.03). The mean values of the overbite were significantly decreased in twin block than in T4k (p < 0.0001). Both groups showed significant dentoalveolar improvements toward class I occlusion; however, the twin block showed significantly better results than T4K appliance.
