ABSTRACT
Dental pain is most commonly associated with the carious destruction leading to inflammation of the pulp or can also be pain present post operatively; however, much of the dental pain can be attributed to dentinal hypersensitivity (DH). The prevalence of DH is high enough (72.5 % to 98 %) to warrant the development of effective treatment. Surveys among dental professionals worldwide suggest that many lack adequate knowledge about this condition and its management. This study aims to assess the knowledge and awareness of postgraduates and faculty regarding dentinal hypersensitivity in a tertiary dental care hospital in Bangalore. METHODSA descriptive cross-sectional survey was carried out among the staff and post graduate students at Rajarajeswari Dental College & Hospital, Bangalore during October 2019. Ethical clearance was obtained from the Institutional Ethical committee. All the staff and post graduate students who were present on the day of study were included in the study. Informed consent was obtained from all the study participants before the study and participation was entirely voluntary. RESULTSMajority of the participants routinely checked for the signs of DH (F - 77.2 % PG - 77 %) and considered DH as a serious problem (F - 87.5 % PG - 87 %). Participants also thought that DH has to be treated with an interdisciplinary approach (F - 75 % PG - 67.7 %). CONCLUSIONSThe study concludes that even though the knowledge and awareness of Dentinal Hypersensitivity was good, there existed uncertainty concerning diagnosis and management of the same.
ABSTRACT
Aim: To evaluate the effectiveness and retention of knowledge of two educational methods such as Mind Mapping and conventional teaching method amongdentalundergraduates. Materials and Methods: This cross sectional comparative interventional study was carried out among nal year dental undergraduates (n=80) at RajarajeshwariDentalCollege&Hospital,Bangalore.Studentsweredividedintotwogroups,GroupA:MindMappingGroup/testgroup(40)andGroupB: control group (40). A pretested questionnaire of 10 questions was used to asesess the knowledge at baseline, immediately after and a week after the intervention.Knowledgegainwastheprimaryoutcomevariableandretentionoftheknowledgeafteraweekisthesecondaryoutcome. Results:At the baseline the mean knowledge score was equal in both the group. Immediately after intervention, the mean knowledge score in the control group increased to 8.8, whereasin the mind map group, it increased to 9.4 and the difference wasfound to be statistically signicant(p = 0.003).

ABSTRACT
Context: In dental practical classes, the acoustic environment is characterized by high noise levels in relation to other teaching areas, due to the exaggerated noise produced by some of these devices and use of dental equipment by many users at the same time. Aims: To measure, analyze and compare noise levels of equipments among dental learning areas under different working conditions and also to measure and compare noise levels between used and brand new handpieces under different working conditions. Materials and Methods: Noise levels were measured and analyzed in different dental learning areas that included clinical, pre-clinical areas and laboratories selected as representatives of a variety of learning-teaching activities. The noise levels were determined using a precision noise level meter (CENTER® 325 IEC 651 TYPE II) with a microphone. The mean of the maxima was determined. The data were collected, tabulated, and statistically analyzed using t tests. Results: The noise levels measured varied between 64 and 97 dB(A).The differences in sound levels when the equipment was merely turned on and during cutting operations and also between used and brand new equipments were recorded. The laboratory engines had the highest noise levels, whereas the noise levels in high-speed turbine handpieces and the low-speed contra angle handpieces were decreased. Conclusion: The noise levels detected in this study are considered to be close to the limit of risk of hearing loss.
