T scans are a breakthrough in technology which allows the user to accurately analyze the occlusion of a patient with minimal to zero errors. They are used during prosthodontic rehabilitation to map out the patient’s occlusion to plan for replacements. Such a high advancement in technology has a backdraw. The cost of the equipment is a concern for simple dental practitioners. There are no large scale studies using T scans in determining the occlusion. Therefore, it is of interest to analyze the use of T scans in determining the percentage of contact in patients with dental implants. This retrospective analysis was done at the Saveetha University hospital set up where patients undergoing prosthesis fabrication for implants were included. Details like their age, gender and the percentage of contact of the implant and percentage of contact on the adjacent tooth were recorded. These details were tabulated and imported to IBM SPSS version 23 for statistical analysis. Chi square test was used to analyze comparable variables. 22 patients were analyzed, the mean percentage of contact of implants was found to be 7.45±9.01 and the mean percentage of contact of adjacent teeth was found to be 10.14±6.7. Thus, T scan is an efficient method in recording the dynamic occlusal contacts of a patient. The use of T scan reveals data pertaining to individual tooth but in the present study there is no statistical significance in terms of exact values comparing implant contact to adjacent tooth contact. Further studies are needed with relation to timing and contact surface of implant prosthesis.

Articaine is a short acting local anesthetic agent which is used for minor surgeries. Although there is reluctance to use it on children, studies have shown that it is safe to use it in pediatric patients above the age of 4 years. This survey aimed to analyse the awareness on the use of articaine in children among dentists. A questionnaire containing questions about articaine, it’s properties and the participant’s general view about the local anesthetic was distributed to the dental students and private practitioners in Chennai. The results were statistically analyzed using Chi Square test. Moreover, 65% of the participants were using articaine in children, 26.51% preferred using articaine in children below the age of 4. On the other hand, 43.18% were unsure about the choice of articaine as their default local anesthetic agent. This survey showed that dental students and the participants with 0-5 years of experience used articaine as a local anesthetic in children with the difference being statistically not significant(p>0.05). Moreover, male dentists showed more willingness to prefer articaine as their default local anesthetic agent compared to females, however the difference was not statistically significant (p>0.05).
