Aim: The aim of this study was to detect the effect of flap technique on crestal bone resorption during healing and loading period in implant supported overdentures. Material and Methods: A total of 8 patients, 5 male and 3 female, ranging from 50 to 70 years of age, having completely edentulous maxillary and mandibular arches were selected for the study the whole study was conducted in 4 phases. In the 1st phase Clinical Diagnosis, Treatment Planning & Denture Fabrication was done. The selected subjects will be diagnosed and treatment planning for new denture fabrication was done. In the 2nd phase the denture insertion was done and if required occlusal correction was be performed. After initial recall visit, patient was recalled again after one week of denture usage. In this visit 1st stage of implant surgery was conducted. Dental implant in the mid symphyseal region was placed following all the surgical protocols. Immediately after surgery first IOPA with RVG was taken. After the surgery the denture was relieved at the surgical site and patient was asked to use the same denture. Subsequently after 4 weeks and after 12 weeks of healing the second and third IOPA with RVG was taken. The computer software was used for measuring the bone level. After 3 months of Osseointegration period in phase 3, the loading of the implant was done by incorporating O ring attachment. Again after 4 weeks and after 12 weeks of loading the fourth and fifth IOPA with RVG was taken. The magnification error was checked. The data obtained was saved using Paint software used in Microsoft 8.1. The data so obtained for measuring the bone levels with the help of computer software (RVG 5100) was tabled and statistical analysis was done. Results: The mean rate of crestal bone loss with time was more during first month (0.35mm) then it decreased in 3rd month (0.51mm) and further decreased during 4th month (0.59mm) and 6th month (0.70mm) follow up period. Conclusion: The concept of single implant supported overdentures provides another option for completely edentulous elderly patients with severely resorbed mandibular ridge & with economic constraints in developing countries.

Introduction: For the patient’s dissatisfaction with the prosthesis, dentist must realize that a patient’s judgment of the treatment outcome is what defines prosthodontic success. All patient’s need is to have a denture which is firm and stable during function. An ill-fitting denture not only brings frustration to the patients but to the dentists as well. So all probable reasons for the looseness of complete denture should be evaluated by the dentist and hence every possible attempt should be made by the dentist to correct it. Aims and Obectives: The aim of this study was to assess the knowledge of looseness of newly fabricated complete denture and its management among dental students of third year, final year and internship, studying in an undergraduate dental college, in the Imphal city of Manipur. The objective of this study was to assess the relationship between the complete knowledge of complete denture fabrication and their practical implementation in the complete denture fabricational procedure. Materials and Methods: A descriptive, cross-sectional survey was conducted using a self-administered questionnaire involving the dental students of 3rd, 4th year and the students doing internship in the Department of Prosthodontics and Crown & Bridge at RIMS, Dental college. Total of 150 students participated in the study. Participants were distributed in three groups having 50 students each from 3rd year, 4th year, and students doing internship. All the  participants signed an informed consent before filling the questionnaire. Descriptive statistics included computation of frequencies and percentages. Nonparametric test, namely, chi-square test, was used for further data analysis; p-value <0.05 was considered statistically significant and vice versa. Results:. Among all 150 participants who were subjected to self-administered questionnaire, seventy eight (78) subjects (52%) reported that looseness was because of improper secondary impression. Eight (08) subjects (05.33% ) reported that looseness was because of under extension of the green stick compound for peripheral tracing. Three (03) subjects (02%) reported that looseness was because of the overextension of the flanges in peripheral tracing or border moulding. Fifty eight (58) subjects (38.66%) reported that looseness of the newly fabricated complete denture was because of improper posterior palatal seal area record. Three (03) subject (2%) reported that they were unaware of the reasons for the looseness of newly fabricated complete denture. Conclusion: The majority of the students of dental college have limited knowledge of the exact reason for the looseness of newly fabricated complete denture on the day of denture delivery. Students faced problem in its management in dental clinics. The looseness of a newly fabricated complete denture was because of the overextensions of the denture flanges as evaluated by Prosthodontist. Students of dental college should be made aware for the all the probable reasons for looseness of a newly fabricated complete denture. In 90% of the cases it is seen that overextension of the flanges is the most probable reason for an ill fitting, newly fabricated complete denture.

Platelet rich fibrin (PRF) is a novel surgical biomaterial which has shown immense healing and regenerative potential with diverse clinical applications. Surgical excision is a routinely employed treatment modality for mucosal oral lesions with or without grafting or repair of the base of the wound. We proposed a hypothesis that covering of the base of excised lesion with this platelet rich fibrin membrane can accelerate the rate of physiological healing process and regeneration. To evaluate the role, efficacy, advantages and adverse effects if any, of placement of PRF membrane grafts over surgical excision sites of oral mucosal lesions. Platelet rich fibrin membrane graft was prepared as per recommendation and established protocols. Patients were selected for surgical excision of localized, superficial oral mucosal lesions after meticulous clinical and radiological considerations and informed consent was taken. After laser excision with safe margins, the base of wound was covered with PRF membrane graft, stitched in place by 3-0 vicryl sutures. The operated site was clinically evaluated at regular intervals and a healing score was calculated and statistically tabulated on the basis of various parameters of healing. A total of 34 patients were included in the study with a male preponderance (21 males and 13 females). Satisfactory and clinically acceptable wound healing was observed in most of the patient with minimal morbidities. Surgical site demonstrated good healing score and clinically complete healing with good epithelialisation was achieved in all patients. Platelet rich fibrin membrane is an effective grafting biomaterial after excision of oral mucosal lesions as it enhances the rate of healing with minimal complications. We recommend further multicentre studies with higher sample size to explore its utility and clinical applications in different avenues of oral and head neck surgery.

Covid 19 have created severe worries, fear & anxiety among every individual. Production of aerosols during various dental procedure have definitive potential of transmitting covid 19 to one another. After three phases of COVID pandemic in India, there is lot of changes and challenges in health care services. The dental treatment have became an issue which need to be well addressed. Out of 500 individual only 410 individual gave their consent for the study. Offline questionnaire survey was conducted among adults above 21 years. The questionnaire included their demographic details and question related to their knowledge and fear of undergoing dental treatment during this pandemic situation. Among 410 individual who participated in the study, 21% of the individual had covid symptoms. 35% told that they are afraid of dental treatment during pandemic where as 45% almost half the individual said they will take the treatment if its only emergency. The main reason for this fear was infection that they can get while getting treated or while in a dental clinic or hospital. The fear of dental treatment during pandemic is not that high. This may be due to recent advances in dental procedure and sterilization. The knowledge of maintaining good oral care is been adapted by maximum individual.

Background: Potentially malignant disorders are highly prevalent in India. In this study, we assessed C-reactive protein (CRP) levels in patients with oral submucous fibrosis (OSMF) and oral squamous cell carcinoma (OSCC). Methodology: Sixty-four patients (OSMF and OSCC) were undertaken and were classified into 3 groups, OSMF patients (Group I, 34), OSCC (Group II, 30), and healthy controls (Group III, 26). Immunoturbidimetry method was used for the estimation of CRP levels. Results: Maximum cases in Group I was seen in the age group 40–60 years (males-10, females-3), Group II in the age group 40–60 years (males-11, females-5) and Group III (males-5, females-6). The mean CRP level in Group I was 6.12 ± 4.5 mg/l, in Group II was 28.4 ± 21.5 mg/l, and in Group III was 3.15 ± 2.19 mg/l. The difference was significant ( P < 0.05). Conclusion: Authors found that OSMF and oral cancer patients had increased CRP levels as compared to healthy subjects.
