Background: Bone healing is an important subject in various fields of dentistry such as prosthesis, implant, surgery, etc. Numerous studies and researches have been done on tooth socket healing process however, most of these studies are histological evaluations and less are radiographic studies. Aim: The aim the Study was the Radiological Change of Post Extraction Socket after Using Beta Tricalcium Phosphate for Understanding of Bone Formation. Methods: The experimental Study was conducted in the department of oral and maxillofacial of in Bangabandhu Sheikh Mujib Medical University Hospital (BSMMU), Dhaka, Bangladesh to find out the common indications of Post Extraction Socket. 20 patients (Group-A) whose full veneer crown were prepared on Alloplastic bone substitute and another 20 patients (Group-B) whose were without alloplastic bone substitute. 40 cases were randomly selected for the study whose common indication of Radiological Change of Post Extraction Socket after Using Beta Tricalcium Phosphate. Clinical examination and evaluation were done from October 2010 to February 2011. Other necessary investigations were done if clinically indicated and to prepare the patient for anesthesia. Statistical analysis of the results was obtained by using window-based computer software devised with Statistical Packages for Social Sciences (SPSS-22). Results: Table shows the distribution of the age of the patients. Majority of the patients 22(55.0%) were of 18-25 years age group and another 15(37.5%) were at their 26-35 age group. Mean age of the patients was 25.97±4.99 years. Conclusion: Both QDSR and LRA methods can be used in evaluation of the rate of bone formation in the tooth socket but the former method is more accurate.

Objective: To assess the dental care needs of people living with HIV who are regularly monitored at Campus University Hospital of Lomé. Method: This was a descriptive prospective survey conducted on patients followed regularly, from January 1 to December 31, 2016. Results: Our study involved 111 patients, 76.58% of whom were female. The most represented age group was between 30 and 39 years old. Fourteen percent of the patients had a CD4˃500cell / mm3 count and 37.5% of the lesions were seen in patients with WHO stage III HIV infection. Mucosal lesions were more common in subjects with low CD4 counts. Periodontitis represented 59.03%, candidiasis 3.47%. Seventy-six percent of the subjects required oral care. Conclusion: People living with HIV have a real need for oral health care. Systematic management of oral health care in in these subjects should improve their well-being and ensure them a life that is more balanced with their serological status.

Introduction: Since its discovery in December 2019 in Wuhan, China, the SARS-CoV-2 virus has rapidly spread the world over. Much research involving the virus, disease and its pathogenesis is now published. However, apart from some case studies, there is no large scale reporting done of the oral findings in patients infected by the virus. Aims: To record the oral soft tissue findings, report significant or peculiar findings, if any, and correlate laboratory and clinical findings, in patients suffering from Covid-19 disease. Methods and material: 101 COVID -19 patients admitted at a tertiary healthcare and medical teaching institute were clinically examined by a trained single investigator (House officer from the department of Dentistry of LTMMC & LTMGH, Sion Mumbai) in September 2020. Results: Thirty-nine patients had oral findings. A majority (twenty-two) had ulcers, seven showed signs of inflammation of their oral mucosa, five had white oral mucosal patches, three had bald tongues, four had angular cheilitis, and two patients had spontaneous bleeding due to oral lesions. Eight patients also had atypical ulcers, mostly on their tongue. These ulcers have, to the best of our knowledge, not yet been reported elsewhere. They could be a manifestation of COVID -19 infections, and the topic of further research. Discussion: COVID-19 patients do exhibit certain oral signs and symptoms, with majority on the tongue.
