Sixty class II restorations were placed in 60 patients, 20-50 years old. The patients were divided into three groups according to the applied restoration technique. In all cavities, etching (N Etch, Ivoclar Vivadent) was applied for 15 seconds and then rinsed. After that bonding was applied and cured for 20 seconds (N Bond, Ivoclar Vivadent). In group 1, Tetric Evo Ceram (Ivoclar Vivadent) was placed in 2 mm increments. In group 2, Tertic N Ceram Bulk Fill (Ivoclar Vivadent) was placed in single increment. In group 3, SonicFill™ (Kerr, Kavo) was placed in single increment by sonic vibration. The restorations were evaluated using modified USPHS criteria at baseline and then after 3, 6, 9 and12 months. After 12 months, 58 class II restorations were evaluated. Two cases were dropped out. All the restorations in the three groups showed acceptable clinical performance according to the modified USPHS criteria. The differences between the techniques weren’t statistically significant. Overall success was 91.3%. Five restorations failed, one in the first group and four in the second group. Both bulk fill techniques performed well over the 12 months observation period. The bulk fill composite resin performed equally to the conventionally layered resin composite during the 12 months of the present clinical study.

Many methods were used to potentiate sodium hypochlorite, one of which is heating of the irrigant. Negative pressure irrigation is a new method of irrigation that was introduced to deliver the solution through the whole root canal length. Sixty single rooted teeth were used in this study. A total of 360 simulated lateral canals were created, 6 in each tooth, with 2 lateral canals at 2, 4.5 and 6 mm of working length. To resemble the clinical situation, a closed system was created by coating each root with soft modeling wax. Roots were then randomly assigned to 3 experimental groups: group 1 (n = 20): apical negative pressure irrigation (ANP); group 2 (n = 20): apical negative pressure irrigation with heated irrigant (ANP + Heat); and control group 3 (n = 18): positive pressure irrigation. The samples were evaluated by direct observation of the images recorded by a photography machine. The results showed that ANP and ANP + Heat were more effective than needle irrigation at lateral canal penetration, but there was no significant difference between the groups 1 and 2. Apical negative pressure irrigation is more effective than needle irrigation in penetrating into lateral canals. Heated irrigant did not penetrate better into these canals.

There is little contemporary literature outlining the knowledge, views and attitudes of dental students regarding the use of the internet in dentistry especially in our country, India. Hence, it was decided to conduct a pilot questionnaire study regarding the internet and its use in dentistry among dental undergraduate (UG) and postgraduate (PG) students. A prospective, cross-sectional, self-designed questionnaire with questions on various aspects of usage of the internet by the dental students was circulated among the UG and PG students at two dental institutes of Belgaum, Karnataka, India: KLE VK Institute of Dental Sciences (KLE VKIDS) and Maratha Mandal’s NGH Institute of Dental Sciences and Research Centre (MMDC). Completed questionnaires were received from 284 out of 335 UG students and 112 out of 196 PG students, with a response rate of 84.8% and 57.14%, respectively. 82.04% of UG and 87.5% of PG students had personal laptops with access to the internet, indicating easy accessibility to technology.

Our study highlights that the internet technology is regularly used for entertainment than for academic purposes.
