Filter by:The main purpose of this study is to evaluate the immunogenicity and safety of inactivated enterovirus type 71 vaccine combined with recombinant hepatitis B vaccine or Group a meningococcal polysaccharide vaccine.
One-hundred and one healthy participants (221 gingival recessions-GRs) were treated from 1987 to 1996. The probing depth (PD), keratinized tissue width (KTW), gingival recession depth (RD), gingival recession width (RW), gingival recession area (RA) were evaluated and considered at baseline and along time. The obtained data will be evaluated and compared.
Enterovirus 71 (EV71), a major pathogen causing hand-foot-and-mouth disease (HFMD) worldwide, is a member of the Human Enterovirus species A, family Picornaviridae. Its infection occasionally leads to severe diseases and death, with central nervous system (CNS) damage. Recently, except of inactivated vaccine, several EV71 vaccine candidates have been evaluated in animals but no final results of clinical trials, such as attenuated vaccine, subunit vaccine. A formalin-inactivated EV71 vaccine (Human Diploid cell, KMB-17 Cell) has been finished phase I, II and III clinical trials and licensed by SFDA in China at Dec. 3, 2015. Based on the results of clinical trials, the protective efficacy of inactivated EV71 vaccine is 97% against HFMD caused by EV71. The phase IV clinical trial has been carried out from July 2016. The purpose of phase IVc is to evaluated the immunogenicity of the inactive EV71 vaccine in large scale population of Chinese children (from 6 to 71 months old) in Hubei Province, China.
Ph.D project: Periapical bone healing after apicectomy with and without retrograde root filling. The aim of this study is to assess periapical bone healing after apicectomy without a filling and apicectomy combined with a retrograde filling material, MTA. Further, we will estimate risk factors in non-healing cases. Study hypothesis: There is no difference in treatment outcome between: Periapical bone healing after apicectomy with retrograde root filling and Periapical bone healing after apicectomy without retrograde root filling
The purpose of this study is to see if we can develop a good graft for oral mucosal tissue that is like the top of the mouth in a "test tube" that could be used successfully in humans. We have already done this successfully mice. The next step is to take a small piece of tissue from a human volunteer and see if we can grow a larger piece of tissue from it outside the human body and graft it back into the same person successfully. We expect that this technique will work. It has already been tried in patients with burns of the skin who have had similar procedures where the skin is grafted back to them. The significance of this research is that oral tissue taken from the top of the mouth or palate is in limited supply and leaves the patient with a painful and uncomfortable post surgery experience. If we are successful with our technique the patient will experience less pain and discomfort from the site that we are using to grow our tissue outside the body than if we had taken it from the top of the mouth or palate. In addition, by waiting longer periods to grow the patient's cells we can make larger pieces of oral tissue than we could have gotten directly from the patient's mouth. Patients who will participate in this study will need to require a soft tissue graft from the mouth to an area that needs additional attached or keratinized mucosa. This will most likely be either in preparation for patients who have or will have dental implants placed. Another subset of patients are those who need scar tissue released or the vestibule of their mouth (area that turns from the gums to the lip) released.
