Objective: to evaluate the clinical performance of the dual shade layering and polychromatic resin composite layering techniques using a randomized controlled trail. Material and Methods: 42 participants (84 restorations) of class IV or class III through and through within a pair of anterior contra-lateral teeth   were randomly allocated into two groups according to technique of composite restoration placement: control “polychromatic layering” and intervention “dual-shade layering”. Follow-up was done at 1 month (baseline) and 1 year. Restorations were evaluated using Visual Analog Scale (VAS), restoration color shade match using Vita Easyshade V ®, and blinded assessor using FDI criteria for assessment of dental restorations measuring (aesthetic properties). Chi-square test was used to compare between restorations of both techniques. Results: There was no statistically significant difference between restorations of both techniques for patient satisfaction outcome, restorations color match outcome, and for all tested FDI outcomes except surface luster with 100% success. Conclusion: Both dual-shade layering and polychromatic natural layering techniques, exhibited acceptable clinical and esthetic performance.      Keywords Composite; Polychromatic layering technique; Dual-shade layering technique; Clinical performance.

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.

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&lt;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&gt;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&gt;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&lt;0.05). For marginal adaptation, a significant difference was observed between baseline and 24 months for all the restorative resins (p&lt;0.05). All the restorative resins tested performed similarly and showed acceptable clinical performance during the 24-month evaluation.

Treatment of dental caries in children still remains challenging due to lack of cooperation with conventional treatment modalities. Recently, the use of Silver Diamine Fluoride (SDF) has proved useful in addressing this challenge. Aim: This clinical trial aimed to evaluate the effectiveness of Silver Diamine Fluoride (SDF) in arresting caries in children in Lagos, Nigeria. Methods: This was a phase III balanced randomized controlled school based interventional study on 240 children. The study group was treated with SDF while GIC was used in the control group. Follow up visits in 2 weeks, 1 month, and 3 months were carried out to assess the treatment outcome. Inferential statistics with the use of Pearson Chi-square test and Independent Student t-test were used at 5% level of significance. Results: There was significant relationship between SDF and caries arrest in 2 weeks, 1 month and 3 months’ assessment period (p = 0.001). The control group showed continuous decline (71.7%, 54.3% and 50.9%) in restorative success from 2 weeks to 3 months respectively. The mean ± SD and Confidence Interval (CI) of arrested caries in the SDF group were 113± 1.24 and 113.1 – 113.5 respectively. In the control group the mean ± SD and CI of restorative success were 69.3±11.8 and 67.2 – 71.4. The effect size was 5.24. Conclusion: The result of the study showed that SDF was effective in arresting caries in children without any harm and there was statistically significant difference in the use of 38% SDF in arresting caries in children.

SUMMARY Objectives: The aim of this study was to evaluate the clinical performance of a nanofill and a bulk fill resin composite in class II restorations. Methods and Materials: In accordance with a split-mouth design, 50 patients received at least one pair of restorations, restored with a nanofill resin composite (Filtek Ultimate [FU]) and with a bulk fill resin composite (Tetric EvoCeram Bulk Fill [TB]). Each restorative resin was used with its respective adhesive system according to the manufacturers' instructions. A total of 104 class II restorations were placed by two operators. The restorations were blindly evaluated by two examiners at baseline and at six, 12, 18, 24, and 36 months using modified US Public Health Service Ryge criteria. The comparison of the two restorative materials for each category was performed with the chi-square test (α=0.05). The baseline scores were compared with those at the recall visits using the Cochran Q-test. Results: At six, 12, 18, and 24 months, the recall rate was 100%, 98%, 94%, and 82%, respectively, with a retention rate of 100%. At 36 months, 81 restorations were evaluated in 39 patients with a recall rate of 78%. For marginal adaptation, four restorations from the TB group and 10 from the FU group rated as Bravo. Two restorations from the TB and eight restorations from the FU group showed marginal discoloration. There were statistically significant differences between the two restorative resins in terms of marginal adaptation and marginal discoloration (p&lt;0.05). No differences were observed between the restorative resins in terms of retention (p&gt;0.05). One restored tooth from the FU group was crowned. The retention rates for the TB and the FU groups were 100%. In the FU group, two restorations showed slightly rough surfaces, and two showed a slight mismatch in color. None of the restorations showed postoperative sensitivity, secondary caries, or loss of anatomic form. Conclusions: The tested bulk fill restorative resin demonstrated better clinical performance in terms of marginal discoloration and marginal adaptation.

Success of any restoration depends on the material used and the skill of the operator. This study aims to compare the clinical efficiency of postgraduates of various years in placing stainless steel crowns in maxillary 1st molars and thereby finding how operator skills affect the placement by analyzing their grades. In this retrospective study the dental records of pediatric patients who had visited the dental hospital located in Chennai, Tamil Nadu, India from June 2019 to March 2020 were reviewed. Patients who underwent stainless steel crown placement of at least one primary maxillary 1st molar teeth under local or general anesthesia of 2-6 years of age by postgraduates were included in the study. Out of the 467 teeth treated 268 (57.38%) were of males and 199 (42.61%) females. The percentage of treatment done at various ages were at 2 years: 33(7.06%), 3 years: 110(23.55%), 4 years: 150(32.11%), 5 years: 102(21.84%), 6 years: 71(15.20%). The percentage of crowns placed by postgraduates of various years were 1st year postgraduates: 86(18.41%), 2nd year postgraduates: 170(36.40%), 3rd year postgraduates: 211(45.18%). Chi-square test was done and the association was found to be not significant( p-value = 0.139). The frequency of each tooth treated being primary right 1st molar: 164(35.11%), primary right 2nd molar: 56(11.99%), primary left 1st molar: 180(38.54%), and primary left 2nd molar: 67(14.34%). This data showed that the 3rd year postgraduates got the most number of high grades 211(45.18%). Chi-square test was done and the association was found to be significant (p-value = 0.000). There is a significant difference in the placement of stainless steel crowns among the various postgraduates. There was a gradual increase in the clinical performance with the 3rd years performing the best among the three years.

It is of interest to document the known relationship between periodontal status and Angle痴 malocclusion types. We used 26092 case records of patients between 16 to 50 years of age with no gender restrictions. Variables such as age, gender, periodontal diagnosis and type of Angle痴 occlusion were extracted and tabulated. Statistical analysis was completed using chi square test in the SPSS software version 20. Data shows that the majority (95.27%) had Angle痴 class I occlusion and less than 5% had class II and Class III occlusion. Statistical analysis of class II and Class III cases with 1000 randomly selected cases of class I occlusion show a significant difference in the periodontal status between different types of Angle痴 occlusion. Chronic periodontitis was more in class I (10.4%) and it was the lowest in Class II Div 2 (4.3%) occlusion. Class II Div 1(23.8%) and Class III (17%) had the highest and lowest proportion of clinically healthy periodontium, respectively. Thus, we report that angles occlusion types had significant influence on periodontal status along with the other determinants.

SUMMARY Objectives This study evaluated the two-year clinical performance and volumetric wear of a flowable resin composite compared to a conventional highly filled composite resin in Class I restorations. Methods and Materials In this single-center, single-blinded, comparator-controlled clinical study (Institutional Review Board approved), 120 carious teeth distributed in 60 patients were randomly assigned to four calibrated practitioners who placed occlusal restorations (n=60 flowable and n=60 conventional composite). Direct and indirect assessment at baseline, six months, one year, and two years occurred during which the modified Cvar and Ryge criteria were evaluated. Volumetric wear was determined by superimposition of profilometer scans of baseline and two-year casts. Results At two years, there was no significant difference in anatomic form (p=0.80), color match (p=0.08), marginal adaptation (p=0.89), marginal discoloration (p=0.79), surface integrity (p=0.18), secondary caries (p=0.66), cold sensitivity (p=0.522), occlusal sensitivity (p=0.818), or volumetric wear (p=0.661) between materials. Both materials showed a decrease in all criteria except secondary caries (p=0.95) over time. Two-year mean volumetric wear was 3.16 ± 2.38 mm3 for the flowable composite and 3.43 ± 2.50 mm3 for the conventional composite. Conclusions The flowable and conventional composites used in this study have similar clinical efficacy after two years of service when placed as Class I occlusal restorations having isthmus widths less than one-half the intercuspal distance.

Objective. Bonding failure is a problem in orthodontic therapy and has been associated with orthodontic emergencies and delayed treatment time. The aim of this study is to determine the bracket failure rate among patients undergoing orthodontic therapy. Materials and Methods. From the archives of posttreatment records, 200 total cases were selected, out of which 122 cases had detailed treatment records. Cases with incomplete records, large restorations, or enamel aberrations were excluded from the study. Descriptive statistics were applied to obtain sample characteristics, and a chi-square test was applied to compare the bracket failure between different categories. Result. Out of the 122 samples enrolled in the study, female and male patients comprised 71% and 29%, respectively. Class I malocclusions were the most common problem (56%), followed by Class II (41%) and Class III (3%). The bracket failure rate was 3.43%, and 32% of the patients had an incidence of bracket failure. There was no significant difference in bracket failure among genders ( p = 0.344 ), malocclusion types ( p = 0.191 ), or operators ( p = 0.188 ). The maxillary left quadrant was the most common site of bracket failure, followed by the mandibular right quadrant. Conclusion. Bracket failure is relatively uncommon. It is not affected by the gender or age of the patient or by malocclusion type. The maxillary left and mandibular right quadrants are the most common sites of bracket failure.
