    • The preventive prosthesis: Place of the over denture
      The concept of the supra-radicular complete removable prosthesis allows the dentist to assume an important role in the preservation of natural teeth and supporting structures. In many cases, the teeth that would be extracted can be conserved and this contributes to improving the retention and stability of the definitive prosthesis in a significant way. Bone is a dynamic tissue. The extraction of teeth causes the initiation of bone resorption. When the tension force is received by the bone of the supporting teeth, supplementary bone formation takes place. These forces are produced when they are transmitted to the alveolar bone via the periodontal ligament. Therefore the supra-radicular complete prosthesis may not be the elixir, but it is a positive means of retarding the process of bone resorption and maintaining bone volume as well as restoring esthetics. The aim of our work is to clarify the keys to success in supra-radicular restorations which require a rigorous pre-analysis to reconcile balance optimization with the advantages and inconveniences which will also be discussed.

      • Assessment of Knowledge, Attitude and Practice towards Corona Virus Disease 2019 among Final Year Dental Students in Post Lockdown Period: an Online Questionnaire Based Study Abstract:
        The corona virus disease 2019- COVID-19 is a viral disease that is highly infectious and has claimed many lives till date and is still continuing to consume lives. Literature supports the view that good KAP level is connected with good management of \the health practices. Hence in this study we evaluated the knowledge, attitudes, and practices (KAP) towards COVID-19 among final year dental students. Methods: A prospective, web-based, cross-sectional study was done among 100 final year dental students during October 2020 by a questionnaire using Google forms. p<0.05 was considered significant. Results: On the whole, the students’ knowledge concerning COVID-19 was acceptable they have positive attitude and they trailed healthy preventive practices. No significant difference were found among sexes in knowledge and practice though attitude score was prompted by gender. Conclusions: Maximum dental undergraduates had adequate knowledge levels, positive attitude towards COVID-19 and practices. Nevertheless there are some inconsistencies in the opinions of COVID19. Sufficient training and counseling dental students through organized teaching techniques may help in aiding the public in the need of hour.

        • Efficacy of three-layered closure of oroantralfistula using block graft, buccal fat pad, and buccal advancement flap (Prospective clinical and radiographic study) Abstract:
          This study was designed to evaluate the efficacy of three layered (bone block graft (BBG), buccal fat pad (BFP) and buccal advancement flap(BAF)closure of oroantral fistula(OAF) and replacing the missing alveolar bone. Patients and Methods: Twenty patients suffered from an OAFwere underwent to pre-operative clinical, and radiological examinations to estimate location and size of the fistulaby computerized tomography (CT). OAF in all patients were closed by three layered (BBG, BFP, andBAF) closure. The postoperative clinical evaluation includedcheek dimensions, graft rejection and intensity of pain in the periods 1 week, 3 weeks, 6 weeks, 3 months. The radiological evaluation by cone beam computerized tomography (CBCT) was done to measure the density and height of the bone in the periods 3 ,6, 9 months. All data were collected and underwent to statistical analysis.Results:The estimated level of pain intensity and cheek dimensions gradually decreased during postoperative intervals with statistically significantdifference (p ≤ 0.05). Thepostoperative radiographic evaluation showed statistically significant increase in bone density measurements during follow-up periods (p ≤ 0.05). While the average measurements of bone height decreased at all postoperative intervals with statistically significant difference (p ≤ 0.05) between3- and 6-monthperiodsonly.Conclusion: Closure of OAF with BBG covered by BFP and BAF is a promising modality togive proper anatomical closure for OAF with excellent soft tissue healing allowing for future implant placement in OAF region.
