The purpose of the present study was to assess the influence of cavity size on the survival of conventional and CHX modified GIC in single surface primary molars receiving Atraumatic Restorative Treatment (ART). A randomized controlled trial with a split-mouth design was conducted on 90 children with symmetrical bilateral single surface carious lesions on primary molars. The teeth were randomly allotted to the conventional GIC group (group 1, n = 90) and CHX modified GIC group (group 2, n = 90). Both groups received atraumatic restorative treatment under rubber dam isolation. The cavity size was measured in terms of depth, mesiodistal, and buccolingual dimensions. The survival of ART restorations was measured after 6, 12, 18, and 24 months. The difference in proportion was tested using the Kruskal–Wallis H test, and survival curve estimation was carried out using the Kaplan–Meier method. The overall survival of all ART restorations was 83.3% at 24 months for the total sample. The survival of conventional GIC at 24 months was 83.9%, and for CHX-modified GIC was 82.7% (p > 0.05). The collective overall success of 65.1% was seen in the cavity volume category of 10–29.9 mm3. CHX modified GIC showed high survival percentage (60%) with depth >3 mm. To conclude, no significant difference was observed in the overall survival percentage of conventional and CHX modified GIC. Survival percentage was highest for cavities with a volume of 10–19.9 mm3.

Objective: To evaluate the anxiety in children during occlusal atraumatic restorative treatment (ART) in the primary molars of children; and compare the anxiety for ART procedure performed in school environment and in hospital dental setup. Study design: A randomized controlled trial where One dentist placed 120 ART restorations in 60 five- to seven year-olds who had bilateral matched pairs of occlusal carious primary molars. A split-mouth design was used to place restorations in school and in hospital dental setup, which were assigned randomly to contralateral sides. Anxiety was evaluated by Modified Venhem score and the heart rate of the children at five fixed moments during dental treatment. Results: At the entrance of the children into the treatment room, statistically significant difference between treatment in school environment and treatment in hospital dental setup for venham score and heart rate could be found (P=0.023 and P=0.037 respectively). At the start of the treatment procedure higher venham score and heart rate was observed in children treated in hospital dental setup in comparison with the children treated in school environment , finding was statistically significant (P=0.011 and P=0.029 respectively). During all other three points of treatment, the Venham scores of the children treated in school were lower than those of the children treated in hospital dental setup but statistically not significant (P>0.05). Positive co-relation between Venham scores and Heart rate was established. No statistically significant relation could be established between boys and girls. Conclusions: Overall anxiety in children for ART treatment was found to be less and the procedure was well accepted irrespective of environment where treatment was performed. Hospital dental setup by itself made children anxious during entrance and starting of the treatment when compared to children treated in school environment.

Diametral Tensile Strength

The aim of this study was to compare, in different periods of time, the compressive and diametral tensile strength of a traditional high viscous glass ionomer cement: Fuji IX (GC Corporation), with two new Brazilian GIC's: Vitro-Molar (DFL) and Bioglass R (Biodinamica), all indicated for the Atraumatic Restorative Treatment (ART) technique. Fifteen disk specimens (6.0mm diameter x 3.0mm height) for the diametral tensile strength (DTS) test and fifteen cylindrical specimens (6.0mm diameter x 12.0mm height) for the compressive strength (CS) test were made of each GIC. Specimens were stored in deionized water at 37º C and 100% of humidity in a stove until testing. Five specimens of each GIC were submitted to CS and DTS test in each period, namely 1 hour, 24 hours and 7 days. The specimens were tested in a testing machine (Emic) at a crosshead speed of 1.0mm/min for CS and 0.5mm/min for the DTS test until failure occurred. The data were submitted to two-way ANOVA and Tukey tests (alpha=0.05). The mean CS values ranged from 42.03 to 155.47MPa and means DTS from 5.54 to 13.72 MPa, with test periods from 1h to 7 days. The CS and DTS tests showed no statistically significant difference between Fuji IX and Vitro Molar, except for CS test at 1-hour period. Bioglass R had lowest mean value for CS of the cements tested. In DTS test Bioglass R presented no statistically significant differences when compared with all others tested GICs at 1-hour period and Bioglass R presented no difference at 24-hour and 7-day periods when compared to Vitro-Molar. Further studies to investigate other physical properties such as fracture toughness and wear resistance, as well as chemical composition and biocompatibility, are now needed to better understand the properties of these new Brazilian GIC's.

Microscopy Data

The purpose of this study was to evaluate the surface roughness of four conventional chemically cured glass ionomer cements (Fuji IX, Ketac Molar, Vidrion R and Vitromolar) commonly used in atraumatic restorative treatment (ART) immediately after material preparation. Twenty specimens of each glass ionomer cement were fabricated and surface roughness was measured after material setting. The specimens were further examined under scanning electron microscopy. Data were analyzed statistically by Kruskal-Wallis test and Mann-Whitney test at 5% significance level. Two-by-two comparisons showed statistically significant difference (p<0.05) between all materials, except for Ketac Molar and Vidrion R, which had statically similar results (p>0.05). Regarding their results of surface roughness, the materials can be presented in a crescent order, as follows: Ketac Molar < Vidrion R < Fuji IX < Vitromolar. In conclusion, from the tested glass ionomer cements, Fuji IX, Ketac Molar and Vidrion R presented acceptable surface roughness after setting reaction while Vitromolar showed remarkably higher surface roughness.

Over the past few years, there has been an increase in the number of studies reporting on various aspects of the Atraumatic Restorative Treatment (ART) approach. Five randomized clinical trials in which ART restorations with glass ionomers were compared with amalgam restorations in permanent teeth for a maximum period of 3 yrs constituted the database. This meta-analysis divided the publications into ‘early’ (1987–1992) and ‘late’ (1995-) studies on the basis of improvements in the approach. The analysis showed that, in the ‘early’ studies, single-surface amalgam restorations survived statistically significantly longer than comparable ART restorations after 1, 2, and 3 yrs. This trend did not continue into the late group of studies; no statistically significant difference between the 2 types of restorations was found. Based on the available data, it appears that there is no difference in survival results between single-surface ART restorations and amalgam restorations in permanent teeth over the first 3 yrs.

ABSTRACT Objective: In permanent dentition, different rotary systems are used for canal cleaning and shaping. Rotary instrumentation in pediatric dentistry is an emerging concept. A very few studies have compared the efficiency of rotary instrumentation for canal preparation in primary teeth. Hence, this study was performed to compare the obturation quality and instrumentation time of two rotary files systems – Protaper, Mtwo with hand files in primary molars. Materials and Methods: Forty-five primary mandibular molars were randomly allotted to one of the three groups. Instrumentation was done using K-files in Group 1; Protaper in Group 2; and Mtwo in Group 3. Instrumentation time was recorded. The canal filling quality was assessed as underfill, optimal fill, and overfill. Statistical analysis was done using Chi-square, ANOVA, and post hoc Tukey test. Results: No significant difference was observed in the quality of obturation among three groups. Intergroup comparison of the instrumentation time showed a statistically significant difference between the three groups.Conclusion: The use of rotary instrumentation in primary teeth results in marked reduction in the instrumentation time and improves the quality of obturation.

The Impact

110 Background: The GRID study showed that regorafenib improves progression-free survival compared with placebo in patients with advanced GIST after failure of at least imatinib and sunitinib (HR 0.27; 1-sided p<0.0001; Demetri 2013). At the time of the primary analysis, no significant difference in the secondary endpoint of overall survival (OS) was observed (HR 0.77; p=0.199), but this result may have been confounded by the high rate of crossover to regorafenib (85%) of placebo patients at progression. We conducted exploratory analyses of updated OS data to assess the effect of correcting for this protocol-planned crossover. Methods: The data cut-off for this updated OS analysis was 31 January 2014 (2 years after the primary analysis). OS was corrected using two randomization-based methods: rank preserving structural failure time (RPSFT) and iterative parameter estimation (IPE); both methods are considered as best choice among all correction analytics. Hazard ratios and 95% CI were derived using the Cox model. Results: A total of 139 deaths had occurred at the time of data cut-off: 91 events (68.4% of patients) in the regorafenib group and 48 (72.7%) in the placebo group. A total of 22 patients remained on regorafenib treatment (median duration 2.1 years, range 0.9–2.4). The updated hazard ratio for OS favored regorafenib (0.85, 95% CI: 0.60 - 1.21; p=0.18). Median OS was estimated as 17.4 months in both groups, with crossover from placebo. The corrected HRs for OS are less than the uncorrected HR (Table). Conclusions: The updated analysis of OS in the GRID trial is consistent with the primary analysis. An exploratory analysis correcting for the impact of cross-over on OS suggests a survival benefit for regorafenib in GIST. Clinical trial information: NCT01271712. [Table: see text]
