Clinical Performance of Fiber-Reinforced Nanofilled Resin Composite in Extensively Carious Posterior Teeth of Children: 30-Month Evaluation

Objective: To evaluate the 30-month clinical performance of a nanofilled-resin composite with or without glass-fiber layering in restorations of large cavities in posterior teeth of children. Study Design: A total of 71 restorations were placed in permanent molar teeth of 47 children (mean age 10.9 years) with (FRC; n=35) or without (RC; n=36) fiber layering. One operator placed all restorations. Restorations were evaluated according to the USPHS modified-Ryge criteria at baseline, 6, 12, 18, 24, and 30 months. The data were analyzed using Fisher's exact and chi-square tests and outcomes were compared using the Cochran-Q test (p<0.05). Results: The 30-month survival rates of the restorations were 97% and 97.1% in the RC and FRC groups, respectively. Nanofilled-resin restorations with or without glass fiber-layering showed similarly high clinical performance. No differences were detected between the evaluated criteria when comparing baseline with any of the evaluation periods (p<0.05). After 30 months there were no secondary caries, change in anatomical form or postoperative sensitivity. Only minor changes for marginal adaptation, marginal discoloration, color match and surface texture were observed. Conclusion: It was concluded that nanofilled-resin composite applied with or without glass-fiber layering showed similar and good results in large cavities of posterior permanent teeth in children over a 30-month period.

A paradigm shift in dental caries treatment in paediatric dentistry is viewed towards a wide using of composite resins. This prospective clinical trial are evaluated and compared during 18 months of clinical performance of a microhybrid composite with a nanoceramic resin composite placed in сlass I and II cavities in permanent teeth in children. Thirty one children aged between 7 and 15 years were investigated during this study. About 40 restorations were performed, 50% for each material: a nanoceramic resin composite “Ceram. X Sphere TEC one” and a microhybrid resin composite “Charisma”. The restorations have been estimated by investigators immediately after complete polishing a filling. Clinical evaluation was performed 18 months after replacement by two other investigators using modified USPHS criteria. In addition to hand instruments, a magnifier was used for investigation of the restoration margins. Eighteen fillings with “Ceram. X Sphere TEC one” and 17 fillings with “Charisma” were available. The USPHS parameters were analyzed with the Chi-square test in18 months. The level of significance was p<0.05. Also Green-Vermillion index was used for oral hygiene estimation. There are no failed restorations and secondary caries during the studied period. There were no statistically significant differences among the materials used (p>0.5) regarding the clinical performance. Green-Vermillion hygienic index was 1.48. Thirteen children (43.42%) showed satisfactory level of oral hygiene, 10 children (35.71%) demonstrated good level and 7 children (20.87%) – unsatisfactory level. According to the marginal discoloration and surface roughness criteria, there were no significant differences among the restorative materials (p>0.5). Marginal discoloration was seen in children with unsatisfactory oral hygiene that corresponds to the data of recent study. Marginal adaptation rate was 94.95% for nanoceramic, and 82.35% for the microhybrid restorations. The marginal defects recorded had small detectable defects at the enamel margin of the restorations. According to the anatomic form criterion, there were no significant differences among the restorative materials (p>0.5). Postoperative sensitivity of one nanoceramic and two microhybrid restorations was scored as Bravo at baseline examination, but it disappeared by the 18-months evaluation. For color match criterion, the slight differences were observed in microhybrid restoration in 18 months. This shade mismatch was clinically acceptable (Bravo), with no significant differences noted between the materials studied (p>0.5). The nanoceramic and microhybrid composites have provided acceptable clinical performance over 18-months period. The research pertaining to bigger size of a studied sample and longer observation period is considered advisable to ensure the higher clinical success rate of nanoceramic than microhybrid composite in restoration of permanent teeth in children.

SUMMARY The objective of this longitudinal clinical randomized trial was to evaluate the clinical performance of a nanofilled and a nanohybrid resin composite in Class I occlusal restorations of posterior teeth over the course of 54 months. Forty-one adolescents participated in the study. The teeth were restored with Adper Single Bond 2 (3M ESPE) and nanofilled (Filtek Z350, 3M ESPE), nanohybrid (Esthet-X, Dentsply) and microhybrid Filtek Z250 (3M ESPE) used as a control. After 54 months, the restorations were evaluated in accordance with the modified United States Public Health Service criteria. The McNemar and Friedman tests were used for statistical analysis, at a level of significance of 5%. Five failed restorations were observed during the follow-up. A change to unacceptable restoration occurred for one Esthet-X, two Filtek Z350, and two Filtek Z250 restorations, which received the clinically unacceptable score, Charlie, for both anatomic form and marginal adaptation. Secondary caries and postoperative sensitivity occurred in one Filtek Z250 and one Filtek Z350 restoration. When the five evaluation periods (baseline and six, 12, 30, and 54 months) were compared, significant differences were found in the marginal adaptation of Filtek Z250 and Filtek Z350. Significant differences in the roughness criteria (p=0.005) were also observed when the three composites were compared after 54 months (Filtek Z350 > Filtek Z250 > Esthet-X), always within clinically acceptable limits. The materials investigated showed acceptable clinical performance for Class I restoration after 54 months. Long-term reevaluations are necessary for a more detailed analysis of these composites.

Abstract: In children, caries occurs mostly at the age of 6 to 9 years. At the age of 6 years permanent molar teeth begin to erupt, therefore, they are more susceptible to caries. Moreover, at the age of 9 years, a period of mingled teeth where the number of permanent teeth and of the milk teeth are nearly the same. This study aimed to obtain the prevalence of dental caries of the first permanent molar among students of elementary schools in South Tomohon. This was a descriptive study with a cross-sectional design. The population of this study was 72 students aged 6-9 years old. Samples were obtained by using total sampling method. Primary data were obtained by examination of the teeth and mouth. The results showed that the prevalence of caries among students of elementary schools in South Tomohon was 68.1% (49 students). Based on gender, caries were most frequent among males (68.4%). Based on age, caries were most frequent among students of 8 years old (79.2%). Based on tooth element, tooth 36 had the highest incidence of caries (37.2%). Based on the severity of caries, dentine caries was the most frequent (46.51%).Keywords: dental caries, the first permanent molarAbstrak: Karies merupakan penyakit yang banyak menyerang anak-anak terutama umur 6 sampai 9 tahun.

Purpose: To compare the restorative material used in the treatment of posterior teeth taught and performed in two Dental Schools (UFRGS and ULBRA) and in 8 basic health units (BHU) from the Public Health System in Porto Alegre, Brazil. Materials and methods: Data referring the teaching of restorative procedures using amalgam (AM) or resin (R) were obtained through the analysis of patient’s files and questionnaires applied to final year dental students. Information regarding restorative procedures at BHU was obtained through patient’s records and a questionnaire applied to the dentists. The type of restorative material used in both BHU and Dental Schools were compared by chi-square test. Results: At UFRGS, 327 restorations were performed, 78.28% R and 21.72% AM, and at ULBRA 366 restorations, 92.63% R and 7.37% AM. At BHU, 1664 restorations were performed (35.93% R and 64.07% AM). A major proportion of AM restorations was performed in the Public Health Service in comparison to both Dental Schools, in which resin restorations prevailed (p=0.000). Conclusion: The change from AM to R in the dental material choice for posterior teeth at Dental Schools was not followed by the Public Health System, where the AM is still widely used in posterior teeth.

SUMMARY The objective of this study was to evaluate the 24-month clinical performance of three different bulk-fill restorative resin materials in class II restorations. Forty patients with at least three approximal lesions in premolar and molar teeth participated in the study. A total of 120 class II cavities were restored using Tetric EvoCeram Bulk Fill (n=40), SureFil SDR flow + Ceram.X mono (n=40), and everX Posterior + G-aenial Posterior (n=40) with their respective adhesives according to the manufacturers' instructions. All restorations were placed by one operator. The restorations were evaluated at baseline and at six, 12, 18, and 24 months using modified US Public Health Service criteria by one examiner. The restoration groups for each category were compared using the Pearson chi-square test, while the Cochran Q-test was used to compare the changes across different time points within each restorative material (p<0.05). At the end of 24 months, 94 restorations were evaluated in 33 patients, with a recall rate of 82.5%. There were no statistically significant differences between the groups in terms of retention (p>0.05). At the 24-month recall, two restorations from the SureFil SDR flow + Ceram.X mono group and four from the everX Posterior + G-aenial Posterior group showed slight marginal discoloration and were rated as bravo. No marginal discoloration was observed in any of the Tetric EvoCeram Bulk Fill restorations. Six restorations from the Tetric EvoCeram Bulk Fill group, six from the SureFil SDR flow + Ceram.X mono group, and 12 from the everX Posterior + G-aenial Posterior group received bravo scores in terms of marginal adaptation. No difference was found among the three groups for any of the evaluation criteria tested (p>0.05). There were statistically significant differences between the baseline and 24-month recall in the everX Posterior + G-aenial Posterior group in terms of marginal discoloration (p<0.05). For marginal adaptation, a significant difference was observed between baseline and 24 months for all the restorative resins (p<0.05). All the restorative resins tested performed similarly and showed acceptable clinical performance during the 24-month evaluation.

Scissorbite correction of posterior teeth can often be challenging. For adolescent patients, they may occur due to late eruption of the second permanent molar teeth after appliances are removed, or due to operator preference not to include them on the appliance. This case report describes a 17-year-old patient who had previously been treated with fixed appliances but did not originally have second permanent molars bonded. Complete correction of the scissorbite on the UR7 was effectively achieved in 14 weeks using a minimal system comprising only a palatal mini-screw, molar band and elastomeric chain. CPD/Clinical Relevance: Mini-screws placed in a palatal position can provide an effective way to correct posterior scissorbites.

SUMMARY Objective: To compare the 24-month clinical performance of two different resin composites in class II slot restorations. Methods and Materials: Thirty-seven patients having at least two approximal carious lesions were enrolled in the study. A total of 116 teeth (58 pairs) were restored with either a silorane-based composite (Filtek Silorane) and its self-etch adhesive (Silorane Adhesive System, 3M ESPE) or a methacrylate-based packable resin composite (X-tra Fil) and its self-etch adhesive (Futurabond NR, VOCO GmbH) according to the toss of a coin. The restorations were evaluated at baseline and at six-, 12-, and 24-month recalls by two calibrated examiners according to the modified US Public Health Service criteria. The comparison of the two restorative materials for each category was performed with the Pearson chi-square test. Within group differences of the materials at different recall times were compared using the Cochran Q and Friedman tests. Bonferroni-adjusted McNemar test was used when significant difference was found (p<0.05). Results: After 24 months, no statistically significant differences were found between the two restorative materials for the criteria evaluated. Conclusions: Both silorane- and methacrylate-based resin composites showed clinically acceptable performance in class II slot restorations after 24 months.
