The prevalence of tooth decay and other oral disease are often overlooked indicators of overall public health. To improve the understanding of oral health in El Paso, the City of El Paso Health Department has teamed up with Texas Tech University Health Sciences Center El Paso in a collaborative effort to determine the factors that contribute to poor oral hygiene, and lead to cavities and periodontitis. The team will collect saliva, oral debris, leftover teeth and plaque from children and young adults to study oral infections, markers of inflammation, and other contributors to tooth decay and oral illnesses. Samples also will be stored for future investigations. This joint effort will provide a better picture of oral health in El Paso, and will define a framework for prevention, earlier diagnosis, and better treatment.
The patients with chronic kidney disease suffer from many oral problems affecting the quality of life. The aim of our study is to assess their oral health to provide the proper management and increase their awareness
There are severe deficiency of database concerning the oral health status in both pre-dialysis and end stage renal disease in Egyptian population. Our aim in the present study is to assess the oral health of the chronic kidney disease patients to increase their awareness and minimize all the possible risk factors, to achieve a proper management for all oral problems.
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 IVb is to evaluated the safety and efficacy of the inactive EV71 vaccine in large scale population of Chinese children (from 6 to 71 months old) in Hubei Province, China.
Oral diseases tend to be exacerbated due to delayed diagnosis. Patients avoid visiting their dentist even for regular checkups, and develop late stage disease, jeopardizing the treatment outcome. There is an urgent need for an inexpensive and minimally invasive technology that would serve as a diagnostic aid, allowing 1) efficient early detection and 2) treatment customization. Diagnostic modalities based on the detection of volatile organic compounds in the exhaled air may answer this need. The proposed research aims at investigating signature molecular patterns of common oral diseases, as a first step toward the development of a computerized non-invasive diagnostic breath test, based on the "Na-Nose" device. The proposed research will be divided to three distinct stages. Stages 1-2 will serve for the detection and analysis of Volatile Organic Compounds connected with common oral diseases, and for the characterization of a specified diagnostic nano-receptor array. Stage 3 will serve for the clinical testing of the array and as a proof of concept. In a pilot experiment, headspaces above colonies of S.mutans, S.sanguis, P.gingivalis and F.nucleatum were trapped and analyzed using Gas Chromatography Mass Spectrometry (GC-MS). A unique VOC signature, consisting of 20-35 molecules, was detected for each of the bacterial strains. These promising results allow the development of an algorithm for statistical detection of oral diseases by their VOC profile alone. Bacteria and distressed tissues emit unique VOCs, and additional research is required with other types and strains of bacteria - including cultivation of samples from active periodontal and carious lesions. The results of the proposed research may be revolutionary. A simple and non-invasive air sampling at home or in a drugstore will significantly increase patient compliance and curability rates, and decrease healthcare expenditure.
The purpose of the present investigation is to record and compare bacterial compositions in supragingival plaque samples and saliva samples in subjects discontinuing regular oral hygiene for 10 days. The hypothesis is that the composition of the salivary microbiota might reflect local bacterial alterations in relation to discontinuation of oral hygiene.
The purpose of the study was to assess the effectiveness of Faringomoss in reducing the throat discomfort and pain in patients with acute throat diseases and postoperative patients after throat surgeries.
This study evaluates the safety,three batches consistency and immunity duration of the post-marketing inactivated Enterovirus Type 71 (EV71) vaccine in children aged 6-71 months.This study has two groups:safety observation group and immunogenicity observation group.20000 subjects will receive 2 doses vaccines and be observed for safety among 2 epidemic cycles of HFMD.In the immunogenicity observation group, 900 subjects will be randomly received 3 batches vaccines(2 doses),and blood sampled at days 0 and 56.
Radiation therapy (RT) leads to a markedly reduced salivary secretion rate, which makes it difficult to eat and talk and it is a risk factor for oral disorders such as caries and mucosal infections. A reduced salivary secretion rate is often a life long side-effect of the treatment that seriously affect the quality of life. To reduce these side-effects the patients get preventive and supportive oral treatment in connection with their cancer treatment. However, regardless of radiation doses given, the severity of the problems vary considerably. Therefore, a better understanding on when and why problems occur is important for the identification of subjects at risk and to find better measures and treatments, suited for their individual needs. Dentate subjects were included referred before RT. Data were collected before and during treatment as well as 6, 12 and 24 months after completed RT. Cancer diagnosis, treatment, radiation doses, infections and medication were obtained from medical records. Dietary habits were registered using a questionnaire focusing on intake of carbohydrate-rich food-items and items containing sugar-substitutes. The subjects weight was registered before, during and after RT. A clinical examination was performed before and 6, 12 and 24 months after completed RT. Panoramic x-rays were taken as well as bitewing radiographs. The number of teeth, caries status, oral hygiene were registered. Mucositis was registered during RT. Secretion of stimulated whole saliva was determined. Minor labial and buccal gland saliva secretion rate was determined using the Periotron-method. Microbial samples were collected from the tongue, buccal mucosa and supragingival plaque and microorganisms associated with oral health and oral disorders analysed using cultivation technique. The quality of life was registered using the questionnaires EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire). To address additional symptoms associated specifically with cancer in the head and neck region and its treatment, a complementary 35-item module, the EORTC QLQ-H&N35 was used. The patients also completed the Hospital Anxiety and Depression Scales, HADS, which is used to measure severity of anxiety and depressive symptoms and provides estimates of possible mood disorders in patients with somatic comorbidity.
The gold standard for the treatment of gingival recession, is the coronal repositioning of the flap associated with the subepithelial connective tissue graft. The acellular dermal matrix (ADM) has been used as a substitute a subepithelial connective tissue graft in periodontal plastic surgery and mucogengivais, and has achieved similar results. The use of ADM has the advantage of avoiding possible pre and postoperative complications, as well as overcome the limitations presented by autograft. The different surgical techniques used for root coverage seek predictability and success. For this, besides the type of incision placements flap and graft are of utmost importance because the healing benefit and outcome. The aim of this study is to compare two surgical techniques for root coverage and evaluate which one provides better cosmetic results and less morbidity . 20 adults , nonsmoking patients , showing multiple bilateral gingival recessions , class I or II Miller located in canine, first and second premolars are selected. Both techniques use the ADM as a graft. However , in one Quadrant partial flap will be held together with relaxing incisions through an incision intrasucular , ADM will be positioned 1 mm apical to the cementoenamel junction (CEJ) and the flap will be positioned 1 mm coronal CEJ. In the opposite quadrant a minimally invasive technique periosteal envelope above does not use relaxing incisions , preserves the buds will be held , as well as avoiding any scars, the graft will be used to ADM. The clinical parameters (probing depth, clinical attachment level, bleeding on probing index, height and width of the gingival retraction and height and thickness of keratinized gingiva) will be evaluated 2 weeks after the basic periodontal therapy and after 6 and 12 months to surgical procedures. In addition, measurements of photographic gingival recession with the aid of software will be performed.
