Trends of patient attendance at a prosthetic tertiary care centre during the COVID 19 pandemic: An Observational Study

S20 The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 this level of satisfaction there is need to study patients before as well as after prosthetic rehabilitation to ascertain the selfgoverning impact of prosthesis. Follow up study shows that extra oral prosthetic rehabilitation contributes to patient’s ease, gratification, confidence, contentment, self-respect, enthusiasm and worthiness.

Every speciality of medicine and dentistry has witnessed immense changes in terms of patient attendance and care. There is a dire need to understand and analyse these trends, especially from the Prosthodontic perspective. This would in turn help us understand the nuances of patient attendance for future use Methodology: The pattern of attendance of patients to a Prosthodontics department in an educational institute was studied. An observational database including demographics, treatment needs and the occurrence of emergencies was established pertaining to the patients who reported to the department during this Pandemic. All the relevant parameters were closely studied to set up a framework for future use. Result: Patients reporting with dislodged and /or failing tooth as well as implant supported restorations required immediate attention during several phases of lockdown. Planned and predetermined cases such as infants requiring feeding plates and naso alveolar moulding insertion and adjustments were prominent in their attendance. Overall, the pandemic did reduce the reporting of patients for emergency and elective prosthetic procedures. This will help us re-evaluate the definition of emergencies and factors in certain parameters for future treatment protocols Conclusion: Patient attendance is multifactorial. Establishment of protocols and guidelines for all possible patient presentation scenarios are essential for smooth functioning of Prosthodontic departments during times of emergencies DOI: 10.4103/0972-4052.306368 Accuracy of laboratory scanner by scanning the impressions and dental stone casts of the prepared tooth: An In Vitro study Dr. Sattyam Vikram Wankhade, Dr. Kanchan Aswani Government Dental College and Hospital, Nagpur, Maharashtra, India Purpose: The accuracy of a scanner is determined by two factors: “trueness” and “precision. The purpose of this in vitro study was to determine the trueness and precision of laboratory scanner by scanning the impressions and dental stone casts of the prepared tooth. Method and material: For the evaluation of trueness, the impression and stone model of the prepared mandible first molar were scanned with a laboratory scanner to obtain a stereo lithography (STL) file. Further, the impression and the stone model was removed from the scanner table and fixed on it again and scanned. This procedure was repeated to obtain 20 files for each scan. For precision evaluation, laboratory scanner were used to scan the impression and stone model to obtain a stereo lithography file. Without moving it, scanning was performed 19 more times. First STL file was superimposed onto the other STL files one by one, and by the best-fit-alignment colour-difference maps and reports were obtained. For the comparison of the data between the groups an independent t-test was used. Result: A significant difference was noted for trueness between the impression and stone model scanning, but no significant differences were found for precision. Conclusion: The results may help in advance the digital dental CAD/CAM research and in the clinical field of Prosthodontics.

Dr. Gayathri Devi S K M S Ramaiyah Dental College Background: Mixing ability test is said to be more suitable test for the assessment of masticatory ability. Aim of this study was to assess the chewing efficiency of four different groups using the two colour chewing gum by recently developed view gum software.
