Chlorhexidine and Essential Oil Mouthwashes on Human Beta-Defensin 2 (hbD2) and Kathelicidin (LL-37)...
Mouth and Tooth DiseasesPeriodontal Diseases1 moreRecent studies have shown that while mouthwashes exhibit antimicrobial properties against bacteria and their products, at the same time showing the cytotoxic effect on living cells in the mouth.29 To the best of our knowledge, there is no information about the toxicity effect of these two mouthwashes, which are highly preferred, on antimicrobial peptides secreted from the oral epithelium. Therefore, our aim in this study is to evaluate the effect of chlorhexidine and essential oil mouthwash on hBD2 and LL-37 in saliva.
Information and Communication Technologies (ICTS) in Dentistry for SUS
Dental Caries in ChildrenDental DiseasesAt 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 moreBackground 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.
Low-cost, Noninvasive Method to Assess Pulpal Vitality
Other Dental Disease/Condition of Teeth/Supporting StructureThe purpose of this research study is to find a new way of using light to measure the blood flow within the tooth. The researcher develop dental Laser Speckle imaging system tool that can use for exam condition of the tooth. This device is reliable method to provide information to dentists and endodontists during oral examination.
Intra- and Post- Operative Bleeding After Simple Dental Extraction in Direct Oral Anticoagulant...
Anticoagulant-induced BleedingDental DiseasesDirect Oral Anticoagulants were recently approved for medical treatment of several condition such as, non valvular atrial fibrillation, deep venous thrombosis, and others, substituting sometimes the conventional oral anticoagulants. The aim of the present study is to observe the possible difference in intra-operative and post-operative bleeding events for single dental extraction.

Deep Learning to Summarize Findings in Dental Panoramic Radiographs
RadiographyDigital2 moreIn this work, the investigators study the application of artificial intelligence systems on dental panoramic images for dental findings. An artificial intelligence system will be learned on an publicly available panoramic image dataset, and test against the investigators' local patient cohort as external test data. The investigators hypothesize the performance would be similar, if not identical to on the public data, and that the investigators' AI system is generalizable.
