Overall objective of this work is to develop better ways of detecting, diagnosing and measuring oral diseases and structures using light and optical approaches. All different areas of the mouth will be imaged, including healthy, diseased, dysplastic and malignant, as well as oral biofilm, and the imaging data compared against conventional diagnostic approaches such clinical and histopathological and molecular evaluations to (1) gain a better understanding of processes involved in oral pathology and (2) develop a combined patient specific, non-invasive method for the detection, diagnosis and screening of oral pathology and biofilm. Thus our goal is to identify and evaluate microstructural, metabolic, vascular, protein, genomic and metabolomics biomarkers of oral pathology can be used to detect, predict and map oral pathology, especially neoplasia. We are recruiting patients with a wide range of oral conditions including plaque, dry mouth, toothache, root canal treatments, gum disease, oral sores, dysplasia and cancer, autoimmune conditions and others as well as healthy control subjects. We will use a range of non-invasive imaging modalities to obtain information on the ways in which the oral health status affects optical properties, and determine means of detecting and quantifying these factors.. Imaging modalities to be utilized include: 1. Coherence and Doppler Tomography 2. Laser Speckle Imaging 3. Various forms of Spectroscopy 4. Fluorescence

The investigators wish to investigate the feasibility of using a web based drinking app (www.drinksmeter.com) to reduce alcohol consumption among patients attending an outpatient clinic in a dental setting.
NCT02913235
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.

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.
NCT02357199
This study aims to investigate the prevalence of oral infection in chronic renal disease patients and to examine whether a focused oral hygiene intervention can reduce oral infection leading to reduced systemic inflammatory parameters in chronic renal disease patients in hemodialysis, chronic renal disease patients waiting for kidney transplantation, and chronic renal disease patients who has been transplanted 1-1½ year previously. The results will be compared to a gender- and age-matched healthy control group.
NCT01915966
Xerostomia or dry mouth is the subjective feeling that there is not enough saliva in your mouth. It's a frequent symptom in terminally ill patients receiving palliative care, reducing their quality of life and comfort. Usual recommendations in these patients are good oral hygiene and mouthwashes, ad libitum consumption of camomile and lemon juice infusions, and ad libitum sucking of cold (e.g. ice, ice cream) or citric products (e.g. pineapple). Other xerostomia treatments such as artificial saliva and pharmacological drugs (e.g. pilocarpine) are less used in terminally ill patients due to cost and secondary effects. The purpose of this randomized parallel clinical trial is to determine if a new recipe of gelatin with orange juice, cardamome and ginger is more effective in the control of xerostomia than the usual treatment of camomile infusion with lemon juice against. Treatments will be consumed ad libitum during one week. The main outcome is the subjective assessment of dry mouth at end of treatment.
NCT00000111
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.
