Notes

"How did you know a person's vegan?" They just don't constantly inform you. An empirical check of the do-gooder's dilemma.
One-way ANOVA test was used to compare the different groups.

Significantly more apical extrusion was seen in XP (
< 0.001). Both XP and EA have shown complete penetration of irrigant in the canal (100%).

The aim of this study is to compare the microleakage of bulkfill composite activated by modulated photoactivation between fluorosed and nonfluorosed teeth using the confocal laser scanning microscope.

One hundred and twenty intact human premolar teeth with Thylstrup and Fejerskov index fluorosis index 0-4 were stored in 0.5% thymol at the room temperature until further use. Standardized Class V preparations of 2 mm depth, 3 mm width, and 2 mm height were prepared on the buccal surface. The cavities were etched with 37% phosphoric acid, rinsed and primed with Tetric
bond, cured for 20 s with Quartz Tungsten Halogen (QTH) variable intensity light-curing unit spectrum-800 operating at 450 mW/cm
. Later, bulk fill composite was placed in the cavity and cured. Depending on the curing mode used, all the fluorosed and nonfluorosed teeth were divided into three subgroups each (
= 20) - Conventional light curing, stepped curing, and pulse delayed curing. All samples were stored in distilled water at the room temperature for 24 h and subjected to 500 thermocycles. The prepared teeth were placed in 0.6% rhodamine solution for 48 h; sectioned longitudinally using a hard-tissue microtome and scanned under a confocal laser scanning electron microscope. Data were analyzed using the one-way ANNOVA, Wilcoxson signed-rank test, and Kruskal-Wallis test.

Significant differences were observed between fluorosed and nonfluorosed groups. Intragroup comparisons showed significant differences between fluorosed step and conventional subgroups.

Fluorosed teeth had higher microleakage values than nonfluorosed teeth. Pulse-delayed subgroup had the least microleakage to that of conventional and stepped curing subgroups, in both fluorosed and nonfluorosed groups.

The aim of the study was to compare the fracture resistance of endodontically treated teeth with simulated invasive cervical resorption cavities, restored with different restorative materials, namely, conventional glass-ionomer cement (CGIC), resin-modified glass-ionomer cement (RMGIC), flowable composite (FC), and giomer.

Sixty extracted human permanent maxillary central incisor teeth were assigned to six groups,which were, Group 1 (intact teeth, control), Group 2 (teeth with biomechanical preparation and resorption cavity), Group 3 (CGIC), Group 4 (RMGIC), Group 5 (FC), and Group 6 (giomer). this website Except for Group 1, other groups were subjected to endodontic treatment. Teeth of Group 2 were left unobturated and teeth of Groups 3-6 were obturated. A simulated resorption cavity was prepared labially in the specimens belonging to Groups 2-6 and restored with respective restorative materials. The specimens were subjected to compressive load until failure in an Instron testing machine and the load at failure was recorded in Newtons.

The data obtained were statistically analyzed using one-way ANOVA, pair-wise comparison was made with Tukey's multiple comparison test, and
< 0.05 was considered statistically significant.

There was a statistically significant difference in the fracture resistance of intact teeth and endodontically treated teeth with simulated invasive cervical resorption cavities restored with different adhesive restorative materials. Among the restored teeth, there was no significant difference.

Intact teeth were found to have the highest resistance to fracture followed by those restored with giomer, FC, RMGIC, and CGIC in that order.

To compare and evaluate the shear bond strength of sixth- and seventh-generation bonding agents with varying pH - an
study.

Eighty extracted human premolar teeth were collected and cleaned and polished with pumice and water. The root portion of teeth was resected, and only the coronal portion was embedded in the cold-cure acrylic resin. The labial surface of mounted teeth was prepared with a high-speed handpiece using #245 carbide bur. The samples prepared were divided into four groups, with 20 specimens in each group Group A Sixth-generation bonding agent, Adper Prompt L-Pop (APLP) (3M ESPE)Group B Sixth-generation bonding agent, Xeno III (X III) (Dentsply)Group C Seventh-generation bonding agent, Adper Easy One (AEO) (3M ESPE)Group D Seventh-generation bonding agent, Xeno IV (X IV) (Dentsply). Tooth surface were rinsed and dried, and bonding agents were applied on tooth surface. Composite resin (Z-350 XT, 3M ESPE) was placed in a two-layer increment on tooth and was light cured. Specimens were subjecngth followed by XENO IV(pH = 2.1, GROUP D), XENO III (pH = 1.5, GROUP B) on dentinal surface ,where as ADPER PROMPT L POP (pH =0.7 to 1 Sixth Generation, GROUP A) showed lower bond strength.
Chemomechanical caries removal has been a new leaf for caries excavation in this ultraconservative era of dentistry. BRIX3000 & Carie Care are papain based gel formulations while Smart Burs are polymer burs with self limiting ability.

To compare & evaluate the caries excavation efficacy of BRIX3000, Carie Care & Smart burs.

45 patients with wide class 1 carious lesions were selected and equally divided into 3 groups BRIX 3000, Carie Care & Smart Burs. Caries excavation was performed in accordance with manufacturer's instructions in each group & evaluation for reduction in bacterial count & mean working time was done.

Data was analysed by One way ANOVA, Paired
-Test & Tukey's Post Hoc test.

The highest reduction in bacterial count was achieved by BRIX3000(156.93 × 10
) followed by Smart Burs(139.07× 10
)& Carie Care(135.80×10
) with p>0.5. Mean working time in minutes for excavation was BRIX3000(13.66), Carie Care(18.30) &Smart Burs(20.60) with p< 0.5.

All the techniques reduced bacterial count potentially.
