Background: The prevalence of workplace violence in the healthcare sector is a problem that is frequently ignored and underreported. The performance of healthcare workers who have been the target of violence may suffer, which may have a negative effect on patient satisfaction and health. Aims & Objectives: The purpose of the current study was to determine the prevalence of workplace violence (WPV), risk factors for violence against healthcare workers, and their experiences regarding the same. Methodology: It was a cross-sectional study conducted on 157 hospital staff at Tertiary Care Medical College of Uttarakhand. Data was gathered using a semi-structured, self-administered questionnaire that was modified from the ILO, ICN, WHO, and PSI. Data were analyzed using SPSS software (version 20). Results: Factors like age, gender, job profile, lesser work experience, night shifts, and fewer staff on duty were found to have a positive association with workplace violence. It was observed that the majority of incidents took place in the ward, and the patient’s relatives were the attacker in most of the cases. It was also seen that the majority of Hospital staff did not get bothered by the incident except by staying super alert while dealing with other patients or their relatives. Conclusion: The study concludes that while caring for patients, Hospital staff are at risk of being victims of aggressive and violent situations. To reduce this problem, strategies like training staff in order to handle such incidents in the future should be brought into practice. Laws should be made stricter & assaulting staff on duty should be made a cognizable offense with serious consequences & heavy penalties. Also, the young budding MBBS students should be trained by incorporating these strategies, laws & policies in the CBME curriculum

Background: Dental implants have been a part of our lives since 1965 when studies of Branemark commenced. Today, ever increasing number of dental implants in total or partial edentulous patients provides an outstanding treatment alternative to conventional prosthetic rehabilitation all around the world. However, widespread use of dental implants has brought alone a gradually increasing condition called “disease of peri-implant tissues”. The present study was conducted for assessing the Homocysteine levels in implant failure patients. Materials & methods: A total of 25 subjects with clinical and radiographic evidence of peri-implantitis and 25 healthy controls were enrolled. Complete demographic and clinical details of all the subjects were obtained. Fasting (minimum of 12hrs) venous blood samples were collected. The venous blood was collected in plain vials which will sent to the laboratory for biochemical analysis and evaluation of systemic parameters of both peri-implantitis group and control group. Serum homocysteine was assessed by means of Elisa Immunoassay. Results: Mean serum homocysteine levels among subjects of the control group and peri-implantitis group was 13.27 µmol/L and 25.2 µmol/L respectively. Significant results were obtained while comparing the mean serum homocysteine levels among subjects of the peri-implantitis group and control group.

Materials & methods: A total of 30 subjects with controlled diabetes and 30 healthy controls were enrolled. A Performa was made and detailed clinical profile of all the subjects was enrolled. Thorough oral examination of all the subjects was carried out. Baseline hemodynamic profile and biochemical profile of all the subjects was assessed. Only those subjects were enrolled which required prosthetic rehabilitation for missing mandibular first molar. Dental implant therapy was carried out in all the subjects. After 6 months follow-up radiographic and clinical evaluation of all the subjects was done for assessing the prognosis. Results: Among the controlled diabetic group, success of dental implant therapy was seen in 93.33 percent of the patients while among the control group, success of dental implant therapy was seen in 96.67 percent of the patients. Non-significant results were obtained while comparing the prognosis of dental implant therapy among the two study groups. Conclusion: Under controlled glycaemic conditions, dental implant therapy among diabetic patients had excellent prognosis.

Background: Dental implants have been widely used for the replacement of missing teeth in fully and partially edentulous patients. Titanium (Ti) has been the material of choice for dental implants due to its superior corrosion resistance behaviour and desirable mechanical properties. Hence; the present study was undertaken for assessing the serum metal ion levels in Dental Implant Patients. Materials & methods: A total of 20 subjects with missing mandibular first molar and scheduled for prosthetic rehabilitation for same using dental implant therapy were enrolled. Blood samples were obtained at baseline and sent to laboratory where auto-analyser was used for evaluation of metal ions levels. All the dental implant procedures were carried out under the hands of skilled implantologists. After placement of dental implants, blood samples were obtained at 8 weeks and 6 months follow-up. Metal ions were assessed at subsequent follow-ups. All the results were analysed by SPSS software. Results: Mean serum titanium concentration at baseline, 8 weeks and 6 months was fond to be 2.39 mg/dL, 2.35 mg/dL and 2.38 mg/dL respectively. Mean serum aluminium concentration at baseline, 8 weeks and 6 months was fond to be 4.19 mg/dL, 4.16 mg/dL and 4.18 mg/dL respectively.

Background: Shade determination for direct and indirect restorations has always been a challenging aspect of esthetic dentistry. Hence; the present study was conducted for assessing Interoperator Variability in Shade Selection using Two Shade Guides. Materials & methods: Two different shade guides used were: Shade Guide 1- Vitapan classical shade guide and Shade Guide 2-VITA toothguide 3D-Master shade guide. A total of 40 subjects were enrolled. Only those subjects were enrolled which had healthy maxillary right permanent central incisor. Two independent operators participated in the study. Each subject was seated upright in the dental chair and the middle third portion of the maxillary right central incisor teeth to be matched was slightly moistened. The percentage of variability in shade selection between the operators was calculated. All the results were subjected to statistical analysis. Results: For shade guide 1, kappa value and interpersonal variability was 0.89 and 16% respectively. For shade guide 2, kappa value and interpersonal variability was 0.71 and 29% respectively. Hence; interpersonal variability was higher for shade guide 2 in comparison to shade guide 1. Conclusion: From the above results, the authors concluded that VITA Toothguide 3D-Master showed higher variability in comparison with Vita lumen shade guide.

Background: The present study was conducted for analysing the impact of Complete Dentures on Respiratory Performance. Materials & methods: 20 subjects with presence complete edentulous arch and who had history of complete denture usage for atleast five years were enrolled. Spirometric testing was carried out at following steps: Phase 1: Testing in absence of denture, Phase 2: Testing in presence of both dentures, Phase 3: Testing in presence of maxillary denture only; and Phase 4: Testing in presence of mandibular dentures only. FVC value, PEF value, FEV1 value and FEF25–75 value was recorded with the spirometric test. Analysis of all the results was done by SPSS software, followed by assessment of level of significant with chi-square test and student test. Results: While analysing statistically, it was seen that there was significant decrease in value of Spirometric variables in the presence of dentures. Conclusion: Denture wearer edentulous patients are subjected to risk of development of Spirometric alterations. Hence; these patients should be given timely instructions about various respiratory exercise protocols.

Background: One of the most imperative developments in modern dentistry is the ability to replace missing teeth using titanium implants placed directly into the jaw. Smoking has been associated with countless diseases, including cancer and neurological, cardiovascular, and respiratory diseases. Hence; the present study was conducted for assessing the implant failure rate in smokers and non-smokers. Materials & methods: A total of 100 subjects were enrolled in the present study. All the 100 subjects were divided into four study groups according to their cigarette smoking habits as follows: Group A: 25 non-smokers, Group B: 25 smokers with habit of smoking less than 5 cigarettes per day from past 5 years, Group C: 25 smokers with habit of smoking 5 to 10 cigarettes per day from past 5 years, and Group D: 25 smokers with habit of smoking more than 10 cigarettes per day from past 5 years. Radiographic and assessment of all the patients was done at six months follow-up. Results: Success rate of dental implant therapy among subjects of group A, group B, group C and group D was 100 percent, 92 percent, 84 percent and 76 percent respectively.

Background: The present study was conducted for assessing the impact of relief at the Median Palatal Plate on Denture-supporting Ability. Materials & methods: The present study was conducted for assessing the impact of relief at the Median Palatal Plate on Denture-supporting Ability. In 20 dentulous subjects, pseudopalatal plates were affixed to the palatal mucosa. The relief at the median palatal plate was categorized as: No-relief, 0.25 mm relief, and 0.50 mm relief. All the results were recorded and analysed by SPSS software. Results: During the pain onset, both clenching force and subsidence of the palatal mucosa in the 0.25 and 0.50-mm relief conditions were greater than those under the no-relief condition. The results were found to be statistically significant. However, while comparing in between the 0.25 and 0.50 mm relief conditions, there was no significant difference. Conclusion: The relief area of maxillary full dentures suitable for individual patients was determined in an objective and convenient manner with improved accuracy using this technique.

Background: Patient satisfaction is an important indicator of the quality of services provided by any healthcare organization and directly or indirectly affects patient retention, legal issues, revenues, reputation and success of a healthcare organization. Patient’s feedback about the clinical as well as non-clinical services can be recorded for gap analysis and improvement of services.Methods: The cross-sectional study was carried out in a large tertiary care hospital in North India from May 2012 to December 2012. A pre-tested internally developed questionnaire was used to collect the data.Results: It was observed that the average satisfaction score was relatively high for the criteria like doctor’s counselling, attitude of nurse and availability and behaviour of attendant. The average scores for medical and nursing care (clinical services) provided in wards were high (70-74% satisfaction). However, approximately 45% and 50% patients were dissatisfied with the housekeeping and dietary services respectively. This resulted in a dip in the overall impression of the hospital services to 68%.Conclusions: The percentage of patients satisfied with the overall services (clinical and non-clinical) of the hospital is only 68% which goes on to prove that the patients’ perception of quality is changing with the times and non-clinical areas like housekeeping, dietary, billing, security services are becoming as important as clinical care services that are provided by hospitals.
