Awareness and attitude of parents toward pediatric dental treatment under general anesthesia

BACKGROUND AND AIM: Dental treatment under general anesthesia is critical for non-cooperative, low aged, and special needs’ children. This study aimed to investigate the knowledge and attitude of parents about pediatric dental treatment under general anesthesia. METHODS: This was a cross-sectional study among 100 parents of children who were referred to Babol School of Dentistry (Roohani Hospital) and Babol clinic Hospital, Iran, in 2012-2013 for dental treatment under general anesthesia. The questionnaire contained questions assessing the reasons for choosing dental treatment under general anesthesia, and the advantages and disadvantages of this method of treatment and parental satisfaction. The form was completed by the parents. Data were reported using descriptive statistics and analyzed by the Spearman correlation coefficient. RESULTS: In this study, a questionnaire survey showed that the majority of parents were concerned about the health of their children and despite having some degree of awareness about side effects of general anesthesia and its high cost, they expressed a positive view toward that. A reduction of fear and anxiety and the possibility of performing several treatments in one session are among the benefits of this method. Non-cooperative children of low age with a high number of dental caries are the main recipients of this treatment method. This method was introduced to the majority of parents by the dentist treating their children. CONCLUSION: This study showed parents accepted the costs and risks of this approach to maintain the oral health of their children after it was recommended by the pediatrician. Therefore, with sufficient awareness of society toward this treatment option, we can improve children’s oral health and performance.

Aim: To assess the failure rates of various pediatric dental treatments performed under general anesthesia (GA) after six months to five years of follow-up. Design: This multicenter retrospective cohort study was performed on patients treated by five pedodontists in two private hospitals located in northern Iran during 2010⁻2013 and comprised 155 patients. The patients were recalled and clinically examined. During the clinical examination of the primary teeth, oral hygiene, dmft index, and failure of previous treatments was evaluated. The data were analyzed using the Chi square and regression analyses with a significance level of 0.05. Results: 114 patients (74 males and 40 females, mean age: 37.17 ± 10.75 months) with 1155 primary teeth treated under GA participated in the follow-up. The overall failure rate was 6.59%. The failure rates of pulpectomy, pulopotomy, fissure sealant, stainless steel crown (SSC), amalgam, and composite fillings were 2.90%, 3.03%, 4.83%, 5.26%, 5.33%, and 9.63%, respectively. Among the confounding factors, only gender had a significant effect on the anterior composite failure rate (p = 0.029) and age had a significant effect on the failure rate of fissure sealant therapy (p = 0.015) and SSC (p = 0.018). Conclusion: The overall rate of treatment failure in pediatric patients, treated under GA, was 6.59%

Comparative evaluation of self-adhering flowable and conventional flowable composites using different adhesive systems

Introduction: The ability to seal margins is considered as one of the best predictors for the long-term success of bonded restorations. The aim of this study was to compare microleakage in occlusal and gingival margins between cavities filled with self-adhesive flowable and conventional flowable composites using dye penetration. Composite restorations were bonded with self-etch, total etch and universal adhesives. Materials & Methods: In this in vitro study, 32 extracted human premolars for orthodontic purpose were included. Class V cavities(3x3x1.5mm)were prepared on the facial and lingual surfaces of each tooth. The teeth were randomly divided into four equal groups based on the type of material: Single Bond 2 (3M ESPE), Clearfil SE Bond (Kuraray, Tokyo, Japan), Universal Scotch Bond (3M ESPE), and Vertise Flow (Kerr Corp). Bonding agents were applied according to the manufacturer instructions. Then, the cavities of the first three groups were restored with Filtek Flow (3M ESPE, USA). In addition, the teeth were thermocycled for 30 seconds and 1000 cycles at 5°-55°C. Microleakage was evaluated using a stereomicroscope(x40) .Specimens were subjected to a dye leakage test. Data were analyzed using Kruskal-Wallis and Mann-Whitney U tests. Results: Significant difference was observed in microleakage among four groups in both occlusal and gingival levels (p≤0.05). No significant difference was found regarding microleakage between Vertise Flow, and Etch - and - rinse and Universal groups. Conclusion: Vertise Flow is a useful material with adequate marginal seal

Evaluation of the effect of various types of fluoride varnishes on color stability of a composite resin

BACKGROUND AND AIM: Fluoride varnish as an extrinsic factor may cause discoloration in tooth-colored restorative materials. This research compared the impact of different fluoride varnishes on color change of a composite restorative material. METHODS: This laboratory experimental study was conducted on 40 specimens of flowable composite resin were divided into four groups based on the brand of applied varnishes (Durashield, Nupro, Fluorilaque, and Profluoride varnishes) (n = 10). Color measuring (ΔE) was performed using the easy shade device and according to Commission Internationale de l’Eclairage (CIE) L*a*b* system at three times: 24 hours after immersing in artificial salvia (baseline), 24 hours after fluoride varnishes application and after brushing. The amount of color changes was calculated for all of the specimens as follows: ΔE1 (difference between fluoride application-base line), ΔE2 (difference between brushingfluoride application), and ΔE3 (difference between brushing-base line). P < 0.05 was considered as significant. Statistical analysis was performed by one-way ANOVA and post-hoc Tukey. RESULTS: The maximum and minimum color changes after applying varnishes were observed by Nupro and Profluoride, respectively. A significant difference was observed between ΔE 1 values of all types of studied varnishes (P < 0.01) except Durashield and Fluorilaque (P = 0.35). After brushing, no significant difference was shown between color change of stained specimens due to Durashield, Fluorilaque, and Nupro. There was no significant difference between ΔE 3 values of Durashield and Fluorilaque. CONCLUSION: Trends of color change after using all studied varnishes were clinically acceptable (ΔE < 3.3). Durashield, Nupro, Fluorilaque, and Profluoride varnishes can be used without adversely affecting the color of flowable composite resin. KEYWORDS: Fluoride Varnish; Discoloration; Resin Composit

This shows that the most needed treatment are tooth restoration، root canal therapy and surgical treatment for pain relief

Total antioxidant property and pH change of dental plaque and saliva in 6-11-year-old children after consumption of flavored milk

Introduction: The antioxidant properties of chocolate and other flavored additives besides the sugar added to milk raises the question about the acidogenecity of flavored milk. This study was conducted to measure the pH changes of dental plaque and saliva after the consumption of flavored milk and evaluate the antioxidant property of them. Methods: This study was performed on 42 samples of dental plaque and 42 samples of saliva in 6-11 year old school going children. Milk with flavors of strawberry, chocolate, banana, honey and slim milk were evaluated, all from the same manufacturer with a similar production date. At the beginning of the study on the first day, children were given thorough oral propHylaxis and they were instructed to avoid any method of oral hygiene for 48 hours to permit enough plaque deposition. On the third day the children were divided into 7 groups, 6 children in each group. The supra-gingival plaque was collected through the help of an excavator #3 which was pulled twice with the same force on the tooth surface. The saliva was collected using spitting technique. Each child swished 10 cc of milk for 1 minute in his/her mouth. Fresh plaque samples after 5, 10, 20 and 30 minutes and saliva samples immediately, after 5, 10, 20 and 30 minutes were collected. The pH of the samples were recorded by a pH testing apparatus (Basic 20+, Crisom). To evaluate the antioxidant property of studied milk, Frap test was performed. The collected readings were reported as mean±SD and analyzed by ANOVA repeated measures, Post hoc Tukey and Paired T-test. In this study, p≤0.05 was considered as significant. Results: After 30 minutes, honey milk caused the least drop 0.74±0.30 and banana milk caused the highest drop 1.38± 0.25 in plaque pH (p≤0.05). After 30 minutes, the pH of saliva showed no significant difference compared to the initial pH. Chocolate milk contained the highest (1000 micromol/liter) and banana milk the lowest (706.25 micromol/liter) antioxidant concentration. Conclusions: Because of the highest antioxidant properties and reduction of dental plaque PH to a lesser extent, milk with honey, chocolate and coffee is more recommended for children

Evaluation of microleakage of Ionoseal filling material as a fissure sealant agent

Introduction: Sealing pits and fissures was introduced as an approach to prevent occlusal caries for more than two decades. The aim of this study was to compare the microleakage of flow able resin reinforced glass ionomer (Ionoseal) with other materials used as fissure sealants. Methods: In this in vitro study, 50 premolar teeth of human free of any caries were selected. Fissurotomy was done with fissure bur. The samples were randomly categorized into five groups (Fissurit FX, Fuji II light-cured,Grandio flow, Ionoseal). Ionoseal was assessed by using two methods: with and without etching and bonding agent prior to sealant application. After sealant placement, all surfaces of the teeth except 2 mm area around the sealant margins were covered with two layers of nail polish. The specimens were thermocycled, and they were sectioned after immersing into a 0.5 % basic fuchsine solution. The amount of microleakage was examined by stereomicroscope. Results: The microleakage comparisons of groups indicated that Ionoseal without etching and bonding application had significantly greater microleakage than the other groups (p0.05). Conclusions: By considering isolation difficulties in children and observing high amount of Ionoseal microleakage (without etching and bonding application), the samples need to be etched and bonded like other resin-based materials before Ionoseal placement in order to achieve clinically desirable microleakage outcomes

A comparative study of the effects of QTH and LED light curing units on the surface hardness of colored compomer and Hybrid composites

Introduction: One factor affecting the degree of polymerization is the type of light-curing device. The aim of this study was to compare the effects of LED and QTH light curing units on the surface hardness of composite and compomer. Materials &Methods: In this experimental study, 30 samples of composite and compomer were divided into 3 groups of 10 each. One-half of the subgroups in each group were cured with LED and the other half with Halogen light curing units (LCUs). 49 points on the surface were marked and then the hardness of these points was measured by using Vickers hardness test. Results: The mean hardness of composites cured by using LED was more than the Halogen group but in compomer it was reversed and this difference was statistically significant (p<0.001). Z 250 composite had the highest level of hardness and the lowest hardness was related to the Heliomolar composite and had significant difference (p<0.001). Conclusion: In the present study, the results indicated that LED light curing unit had great effect on the hardness of composites but in compomer, the QTH showed a better result

Treacher Collins Syndrome: A Case Report and Review of Literature

Introduction: Treacher Collins Syndrome (TCS) is an inherited and rare, autosomal dominant condition of craniofacial malformation with varying degrees of penetrance and expression that has been described extensively in the scientific literature with more than 250 cases reported. We presented a 7-year-old boy with TCS. The etiology, clinical features, differential diagnosis and treatment planning have been discussed. In addition, we also reviewed 10 varied cases of TCS. Case Presentation: Syndromic appearance of abnormal orbits, eyes, ear, and facial bones, along with normal physical and dental development and intelligence quotient were observed in a 7-year old boy referred to the Pediatric Department of Babol Dental School. The patient had no family history of any syndrome, and after reviewing his complete medical records and diagnosing oral and dental problems, the treatment plan was devised. Due to the high risk of caries in the patient, he was followed up every three months. Conclusions: Early detection, treatment and particular attention to every case of TCS can reduce disease symptoms. Psychological consultation can improve the quality of life for these patients

Comparison of Surface Hardness of Various Shades of Twinky Star Colored Compomer Light-cured with QTH and LED Units

Introduction: Colored compomers are a group of restorative materials that were introduced in 2002 to repair primary teeth, and they provide attractive color and ease of use in pediatric dentistry. The aim of this study was to evaluate the effect of QTH and LED light-curing units on the surface hardness of different colors of Twinky Star compomers. Methods: In this experimental study, a composite resin (Z250, 3M, and USA), an ionosit compomer (DMG, Germany) with A3 shade and 8 different Twinky Star colored compomer (Voco, Germany) samples were used. In all, 100 samples were prepared with 10 samples in each group, i.e., 10 Z250 composite resin, 10 ionosit compomers, and 10 Twinky Star compomer samples of each color. The samples were prepared in a 4×4-mm Teflon mold. Half of the samples were light-cured with QTH and the other half with LED units. Then, the surface microhardness was measured by Vickers hardness test. The data were analyzed with IBM-SPSS version 22, using the t-test and ANOVA. Results: Two-way ANOVA showed that the mean surface hardness of the compomer samples cured with the QTH unit was significantly higher than that cured with the LED unit (p < 0.001). In each curing unit, surface hardness of some materials exhibited significant differences with the highest hardness being observed in the Z250 composite resin (650.35 ± 56.320) and the lowest hardness being detected in the ionosit compomers (461.10 ± 96.170). One-way ANOVA also showed that, among the different colors of the Twinky Star compomer, the lowest hardness with both units (QTH and LED) was observed in the gold color (214.32 ± 22.026 and 175.116 ± 15.918, respectively). Conclusion: The colored compomer and the type of light-curing unit affected the microhardnesses of the surfaces. Different colors of Twinky Star compomers exhibited different surface microhardnesse
