Everybody Brush: A Community-wide Toothpaste Distribution Campaign

Dental Caries

Dental caries (tooth decay) is a disease with significant public health implications afflicting low-income children, with marked rural disparities in disease prevalence and treatment. More than 70% of 11th grade children in Crook, Deschutes and Jefferson counties have experienced tooth decay. Effective approaches to prevent decay include brushing with fluoridated toothpaste and professional dental care. Medicaid enrolled children are legally entitled to dental care under Early Periodic Screening, Diagnosis and Treatment (EPSDT), yet <50% had any care in 2010. Free distribution of toothpaste and toothbrushes combined with parental education can increase toothbrushing frequency and reducing tooth decay. However, many parents are confused about when to start, how much and often toothpaste should be used, and how to overcome behavioral difficulties in brushing toddlers' teeth or getting older children to brush their own. The investigators' objective is to implement and evaluate a community-wide toothpaste distribution campaign enhanced by telephone support for OHP children and adolescents and their families in Central Oregon

Clinical Study 3MESPE Crowns

Dental Caries

This clinical study seeks to address four independent questions that are all part of the delivery of care associated with the provision of a single item of treatment; an indirect restoration (known as a 'crown') to restore and cover a damaged tooth. The provision of a crown requires a series of sequential clinical and laboratory stages stages: Stage 1 - Preliminary impression. Taking a pre-operative impression of the tooth to be crowned. This will be used to enable the fabrication of the temporary crown after the tooth has been prepared. This is standard care and follows established clinical protocols. Stage 2 - Preparation of the tooth. This involves cutting the tooth back to make space for the crown that will be fabricated to replace the missing structure. Stage 3 - Taking an impression of the prepared tooth. From this a duplicate model will be made to fabricate the crown. To take the impression, the dentist will need to gently push the gums away from the tooth by fractions of a millimeter so that the margins of the preparation are clearly discernible. Stage 4 - Provision of a temporary restoration that will provide satisfactory function for a limited period of time, until the definitive crown can be fitted. This temporary crown is designed to have a finite short-term durability and have an ease of manufacture and subsequent removal; hence the use of a specific cement that will enable this. Stage 5 - Fitting of the definitive restoration. This is designed to be a durable restoration, with a mean life expectancy measured in years, but which is ultimately determined by a number of clinical, biological and patient specific parameters. Definitive restorations are fitted with cement designed to retain the crown in permanent manner.

DIMOH: New Digital Methods for Monitoring Oral Health. An in Vivo Assessment

Dental CariesTooth Wear

The objectives of this study are i) to monitor the oral health of young people over a period of one year and ii) to assess the ability of a new intraoral scanner combining fluorescence with 3D imaging to detect and monitor changes in the dental hard tissues in vivo. The working hypotheses of this study are that i) the monitoring of oral health will benefit from using a new intraoral scanner combining fluorescence with 3D imaging and ii) the new intraoral scanner combining fluorescence with 3D imaging will aid dentists to identify changes in the dental hard tissues at earlier stages than the traditional diagnostic methods (i.e. visual-tactile, radiographic methods).

Information and Communication Technologies (ICTS) in Dentistry for SUS

Dental Caries in ChildrenDental Diseases

At the time of the COVID-19 pandemic, thousands of children had their dental care interrupted or postponed, generating a pent-up demand for primary care. In order to minimize the impact of this outage of face-to-face care, information and communication technologies could be an alternative and even likely to be envisioned within the Brazilian Unified Health System (SUS). In this sense, this study sought to show the impact of the use of information and communication technologies (ICT) in the resolution of the pent-up demand for primary dental care to children in the SUS, due to the COVID-19 pandemic, proposing the use of telemonitoring, teleorientation and telescreening to resolve and address demands arising from this outage in primary elective care. The impact of the use of these strategies will be measured in terms of problem-solving, reduction of waiting time to resolve complaints and caregivers' perception about received care. For this, two clinical studies were designed and a primarily trial-based economic evaluation was planned. Mathematical models will be used to transpose these results into the reality of the SUS, in view of the State Health Secretariat of São Paulo and different Brazilian scenarios. Finally, the investigators also aim to study the possibility of implementing these technologies mentioned in the daily life of the SUS, even after a pandemic, and to check the possibility of incorporating and costing them, as well as exploring possible social impact and relationship with possible inequities in health.

Post-radiation Dental Disease Amongst Head and Neck Cancer Patients

Head and Neck CancerCaries3 more

Background Post-radiotherapy head and neck cancer (HANC) patients are at increased risk of dental caries and periodontal disease due to radiation-related damage to the teeth and salivary glands. Currently the exact aetiology of post-radiotherapy dental disease, and variation in its incidence and severity based on tumour location and radiotherapy dose, is poorly understood. Consequently there is a lack of clear guidance on how HANC patients should be dentally managed both before and after their radiotherapy. Aim The aim of this study is to quantify the relationship between dental radiation dose, 'spared' parotid gland radiation dose, tumour location, and post-radiotherapy dental disease. Methods A prospective cohort study will be undertaken in HANC patients treated with radiotherapy. A total of 215 patients will be recruited over a period of 2.5 years. Participants will be assessed and rendered dentally fit prior to radiotherapy in the School of Dentistry, Belfast. All patients will be followed-up at 6, 12, and 24-months post-radiotherapy. Data to be collected at each visit will include: total number of carious teeth, periodontal disease indices, salivary flow rates, diet, oral hygiene, mouth opening, xerostomia and oral health-related quality of life. Radiotherapy, including individual tissue-dose exposures, will be prescribed by the Clinical Oncology team as per current practice. Doses to the teeth and 'spared' parotid gland will be determined using radiotherapy research software (Non-Clinical Eclipse System sold by Varian Medical Systems UK Ltd). Using appropriate statistical tests, data analysis will determine the relationship between dental disease, radiation dose, and tumour location. Anticipated variation in the incidence and severity of post-radiotherapy dental disease based on the radiotherapy dose and tumour location, will inform the development of a clinical risk-assessment tool that will allow dentists to categorise patients as 'high' or 'low' risk of future disease. Guidelines regarding pre-radiotherapy dental extractions and post-radiotherapy preventative strategies will also be developed and will advise clinicians based on this risk assessment. A micro-costings study will be undertaken to evaluate patient and healthcare costs associated with the diagnosis and management of pre- and post-radiotherapy dental disease.

Effect of Trait Anxiety in Women on Oral Health Status and Oral Health Care-Seeking Behavior

Anxiety DisordersOral Disease12 more

Trait anxiety is the tendency of an individual to perceive environmental stimuli such as different events and situations as threatening; it's stable and reflects how an individual generally feels. In 2015, it was estimated that 3.6% of the population lived with anxiety disorders globally, i.e. approximately 264 million people lived with anxiety disorders worldwide of which 31.36 million resided in the Eastern Mediterranean region, that's to say, 10% of the global number of anxiety cases. Moreover, females were more affected than males in a proportion of 4.6% as opposed to 2.6% respectively. The prevalence of anxiety has increased by 14.9% from 2005 to 2015. In addition, in 2017, approximately 42 million new cases were recorded globally. In Egypt, the total number of anxiety cases were more than 3 million in 2015 thus indicating that 4.2% of the total population lived with anxiety. Anxiety may affect the individual's utilization of dental services and predispose to a delay in seeking dental treatment and thus might compromise the overall oral health. Accordingly, this study aims to investigate the effect of trait anxiety on the oral health status of women and determine their behavior towards the utilization of dental services. To our knowledge, no previous research has been conducted to assess such relationship in Egypt.

Clinical Study Class II on Ceram.x Universal and Prime&Bond

Dental Caries

Damage to teeth from decay or previous old silver fillings can be repaired with tooth-coloured filling materials that stick to the tooth. These materials have been around for some years and have become more sophisticated; with greater ease of placement by the dentist and better durability for the patient. The fillings are designed to be used in combination with a specific glue (adhesive) that is designed to stick to the different parts of the tooth to provide a good seal, the outer enamel and the inner dentine. This study will examine the performance of a state-of-the-art modern tooth coloured filling material (Ceram X) in combination with an existing adhesive (control adhesive) and a new adhesive (Prime & Bond Universal) used in two different techniques; both of which are known to work but one is easier to apply. This results in three treatment groups. At the start of the study, the test material Prime&Bond Universal is CE-marked, as are all other medical devices used. Thus, this study is not conducted to meet any regulatory requirements. The rationale of this study is the extension of knowledge primarily concerning the clinical performance of Prime&Bond Universal in molars. Two investigators (to be confirmed) will place a minimum of 25 restorations per group (75 restorations in total) to assess the performance of the materials in a comparative design. The study restorations will be monitored for a period of 18 months (with the option to extend the evaluation period to 48 months). After placement of restorations under controlled clinical conditions, the primary objective of the study is the determination of post-operative sensitivity and pulp vitality, marginal adaptation and staining of margins of the restorations. In addition, fracture of material and retention, recurrent caries, occlusal contour and wear, approximal anatomical form will be determined as well as the failure rate as defined by the ADA.
