This study was conducted to evaluate and compare the incidence of Lower back pain (LBP) and muscle fatigue among oral and maxillofacial surgery residents during exodontia procedure in standing and sitting position This included a total of 24 participants out of which 11 (45 %) were male and 13 (55%) were female. All the participants were in the age group of 25-29 years. Participants were predominantly right-handed 83 percent of total participants. Root mean square was calculated for all subjects before and after extraction in sitting and standing position separately. A pre-extraction root mean square (RMS) value was in the range of 40-110 mv and post extraction, participants showed increased muscle activity, with RMS values ranging from 170 to 200 mV. Standing position resulted in higher muscle activity compared to sitting position. The study concluded that even though muscle fatigue is present both in sitting and standing position. Sitting position comparatively causes less muscle activity and thereby less muscle fatigue, use of ergonomics chair could further decrease the muscle fatigue associated with sitting position. Maintaining correct ergonomic positions while performing surgical procedures can lead to decrease in evidence of work related Musculo-skeletal disorder (MSD) and improve the quality of life.

Background: Stress is generally known as a silent killer which manifests as increased anxiety, pertaining to a particular event. Surgery of any kind leads to stress which is inevitable for the patient. The reduction of stress is vital for patient satisfaction and successful clinical practice. One of the ways to reduce presurgical stress is listening to music. The aim of the study was to compare the effectiveness of classical piano music (PM) and Gayatri mantra (GM) on presurgical vital parameters of patients undergoing major maxillofacial surgery under general anesthesia. Patients and Methods: Forty patients requiring maxillofacial surgery under general anesthesia were included. They were divided into two groups. In Group 1, patients listened to PM and in Group II to GM before being induced. Patients were chosen alternatively and connected to noninvasive blood pressure monitor. Readings of vital parameters, i.e., pulse rate, respiratory rate, and blood pressure, were recorded and statistically evaluated. Results: Pulse showed a 3%– 5% decrease in value for the PM group versus a 0.4%–3.3% decrease for the GM group. Systolic blood pressure showed a maximum decrease of up to 4.3% for PM group as against 3.8% decrease for GM group. PM showed a greater decrease in the vital parameters compared to GM. Conclusion: Listening to classical PM 30 min before induction of general anesthesia results in reduced patient anxiety and a smoother induction for the anesthetist. [ABSTRACT FROM AUTHOR]

Background: Dental implantology is technique to replace missing teeth. Crestal bone loss along implant surface jeopardizes its longevity and success of treatment. The bone must remain healthy after dental implant is placed for the dental implant to last. However, the bone surrounding a dental implant is sometimes lost. There are several reasons for bone loss around a dental implant. In most cases, the bone loss starts at the top of the crest and progresses around the dental implant to form a saucer type defect. Materials and Methods: About 10 two-stage implants of life care implant system and 10 two-stage implants of Noble biocare implant system were placed in patients in fourth quadrant. Digital orthopantomograph (OPG) was taken on day of implant placement. After 6 months, at time of second stage surgery, the implant stability was evaluated by the periotest instrument. The crestal bone loss was evaluated on digital OPG. Same procedure for each system was carried out. Results: About 6 months after the implant placement, radiographic evaluation on digital OPG showed a mean crestal bone loss of 1.6 mm on the mesial side of implant and 1.8 mm on distal side of implant for Noble biocare system and radiographic evaluation on digital OPG showed a mean crestal bone loss of 0.7 mm on the mesial side of implant and 0.6 mm on distal side of implant for life care system. Conclusion: A study was conducted to evaluate crestal bone loss, occurring 6 months after implant placement in two implant systems, before loading it. More stress should be given on developing implant collar design to reduce the initial crestal bone loss. The smooth polished collar design of the implant may have contributed to crestal bone loss.
