Individual Variability of Experimental Gingivitis Response
GingivitisOral DiseaseThe study aims to investigate the genetic cause of the variability between individuals seen in the development of the gum disease, gingivitis. This will be carried out through a 3 week programme where all oral hygiene is ceased, allowing 'experimental gingivitis' to develop, followed by a period of recovery when tooth cleaning is restored. Clinical assessments and biological samples will be taken during the course of the study for further analysis.
Oral Health in Adults: Social Gradients and Correlation With Cardiovascular Health
Oral DiseaseCardiovascular Diseases1 moreNon-communicable diseases (NCDs) are rising in prevalence because of aging, unhealthy diet and sedentary lifestyle, and common NCDs are caries and periodontitis (here oral diseases) and cardiovascular disease (CVD). Association between oral diseases and CVD has been observed in epidemiological studies, and suggested mechanisms include transfer of oral pathogen bacteria and pro-inflammatory mediators to other organs triggering immune response and systemic inflammation. Circulating mediators may initiate a response in the liver with production of C-reactive protein, serum amyloid A and increased tryptophan degradation, that contribute to CV inflammation and atherosclerosis. We have demonstrated that higher serum levels of these markers are associated with presence of hypertension and obesity and with higher risk of CVD. However, CVD and oral diseases also share many of the same risk factors, including hypertension, obesity, diabetes and smoking. Since the association of oral disease with CV risk factors mostly has been demonstrated in cross-sectional studies, the direction has not been ascertained. These CVD risk factors lead to changes in the heart and arteries (preclinical CVD); more harmful in women than men. If these conditions can impact development of oral diseases is not been investigated in large studies. Socio-economic inequalities have been reported for oral diseases and are linked to low socio-economic status (SES). It is unknown whether CV health and SES in midlife may impact prevalence of oral diseases later in life. It is also unknown if the oral microbiome differ by periodontitis severity and can be associated with inflammatory biomarkers, CV risk factors and preclinical CVD. The project will be performed in adults approaching the retirement age in Vestland county. We will combine their data from the ongoing Hordaland Oral Health Survey with their data from three surveys in the longitudinal Hordaland Health Study performed in the period 1992-2020.
Effectiveness and Retention of Pit and Fissure Sealants in Rural Setup: A School-based Clinical...
Dental Caries Pit and FissureOral DiseaseThe program titled "Campus to Community: breaking the barrier in oral health education and dental care" is uniquely designed program to link University (Kathmandu University School of Medical Sciences) to community (Sanghutar, Ramechhap). Dhulikhel Hospital, Kathmandu University Teaching Hospital has established a model dental clinic in the premises of Him Ganga Secondary School, Shangutar which is operated by council registered Dentist and dental hygienist. The objective of this study is to assess oral health condition of the children aged 6-15 years of the school followed by application of pit and fissure sealant (PFS) in non-carious permanent molar and Silver diamine fluoride (SDF) in carious permanent teeth. Data will be recorded according to the WHO Oral health assessment form for children, 2013 by a calibrated dentist from Dhulikhel Hospital and retention of PFS and efficacy of SDF application will be followed up after 6 months by the same investigators. The program is proposed with the expectation that proper oral hygiene prevention program combined with preventive procedures like pit and fissure sealant and SDF can reduce the burden of oral diseases in rural setup.
RCT on Effectiveness of Oral Health Preventive Programmes in School Children in Uganda
Dental CariesDental Plaque4 moreDental caries represents a challenge for Oral Health Services in several African Countries, like Uganda. Few studies have been reported the burden of oral health, its prevention and non-operative treatment among school children in African countries. Aim: To assess the prevalence and risk factors of dental caries and the effectiveness of strategies to prevent and treat dental caries using a non-operative approach among children in Gulu Municipality, Uganda. Methods: The proposal RCT is structured in three phases: 1. A descriptive cross-sectional survey to collect oral data among 610 school children selected using a multistage cluster sampling; 2. A randomized unblinded two-arm trial to assess the difference in the treatment/prevention of dental caries using non-operative means among school children in the Ugandian Gulu municipality; and 3. A comparison of oral health conditions between a group of children who will be given dental cleaning tools and followed up over time versus a control group. The oral health status of the participants will be assessed according to WHO and ICDAS guidelines. Stata 14.0. will be used for analysis; descriptive statistics will be carried out to analyze continuous and categorical variables and chi-square test as well as independent tests for bivariate analysis and modified poisson regression. In addition, the factors associated with dental caries will be determined by linear regression models using a statistical significance level of 5% (α = 0.05). Discussion: This trial will be the first trial conducted in Uganda assessing a school-based caries prevention programme using the WHO and ICDAS standardized international guidelines. The findings obtained will increase knowledge on oral health in Uganda school children and the effectiveness of community-based caries prevention programme in this population.

HandFoot and Mouth DiseaseThis is an open,observational and follow-up clinical trial based on the clinical trial of EV71 vaccine extended age group.The purpose of this study is to evaluate the immunity persistence of EV71 vaccine developed by Sinovac Biotech Co., Ltd in subjects aged 6 ~71 months after full immunization of two doses of vaccine.
Assessment and Remediation of Oral Disorders
Oral DisorderAs part of the Reference Center for Rare Diseases of the Robert Debré Hospital, many children have eating and verbal oral disorders. In this doctoral research, we question the psychological impact of oral disorders on the dynamics of family functioning.Our research entitled: Evaluation and Remediation of Orality Disorders (ERTO) aims to evaluate the impact of psychological care of the child and a support program for parents. We hypothesized that this comprehensive management could contribute to improving disorders and consequently modify parental representations of the child and his disorders. In addition, care focused on intra-family relations and communication would allow a decentralization and a repositioning of the problem of disorders within the family dynamic. The results of this research will have concrete applications for the management of children suffering from oral disorders.

Regular Antibacterial Photodynamic Therapy on Oral Hygiene in Elderly Residents
Dental PlaquePus Collection3 moreAround 40 people will participate in the study. The study participants will be recruited from service homes in the City of Helsinki. The subjects will be randomized into two groups. One of the groups will receive daily photodynamic Lumoral treatment for 2 months in a home care unit according to a separate instruction manual. At the beginning of the study, all subjects will receive an oral cleaning and will also be provided with electric toothbrushes. In addition, residents and care home personnel will be instructed on daily tooth cleaning. During the study, all participants will undergo clinical measurements and an assessment of the oral inflammatory load. The samples will be stored for later analysis. In addition, residents or care home personnel answer questions about oral self-care. These measurements and examinations will be carried out at the start of the study and two months after the start of the study. After the end of the study, participants will continue to be treated according to their usual care and individual care plan.
