Active clinical trials for "Tooth Erosion"

The aim of the present study is to evaluate dental erosion in patients with gastroesophageal reflux disease (GERD). Patients consenting to participate to the study will undergo periodontal evaluation at the baseline. Then, professional dental hygiene will be performed. Patients will be randomly assigned to: Trial group: home oral hygiene with Biorepair Total Protection + Biorepair Shock Treatment twice a day Control group: home oral hygiene with Biorepair Total Protection Patients will be evaluated after 1, 3 and 6 months from baseline.

The researchers are doing this study to find out more about what may lead to the loss of tooth enamel (the thin outer covering of the tooth) and how often it happens in people with esophagogastric cancer, colorectal cancer, pancreatic cancer, breast cancer, head and neck cancer, or non-small cell lung cancer, or a healthy volunteer.

The aim of this study is to investigate whether smoking is associated with changes in salivary composition and/or predisposition to erosion. Healthy volunteers are observationally wearing an intraoral device with both bovine tooth specimens (enamel and dentin) and resin specimens twice for two hours each. Afterwards, specimens are eroded extraorally and calcium release into the acid is measured. Total protein concentration and protein composition of the salivary pellicles on the resin samples are measured. Additionally, salivary parameters (unstimulated and stimulated saliva flow rate, pH, buffer capacity, and total protein content as well as concentration of inorganic calcium, phosphate, and fluoride) are measured.

This study will follow a randomised, double-blind, cross-over design. Participants will use mouth rinses containing plant extracts and/or fluoride, as well as a mouth rinse containing only water (placebo). They will use oral appliances containing sterilized enamel and dentine slabs, which will be later collected for analyses. The cross-over design will allow participants to use all rinses, allowing for a comparison between the rinses within each individual.

This will be a randomized, controlled, single center, single- blind, 3 period, 3 treatment, cross-over, in situ design which consists of placing pre-eroded bovine enamel specimens intra orally using a palatal appliance and testing the remineralizing performance of the experimental (dentifrice containing 0.254 Percent weight by weight [%, w/w] sodium fluoride (1150 parts per million [ppm] fluoride) and 5% KNO3 [potassium nitrate]), comparator (dentifrice containing 0.454% w/w stannous fluoride (1100 ppm fluoride) and placebo (Fluoride free placebo containing 5% KNO3 [0 ppm fluoride] ) dentifrices 2 and 4 hours (hrs) post treatment application, based on surface micro hardness measurements. This study will be carried out in healthy adults with a maxillary dental arch suitable for the retention of the palatal appliance.

The purpose of this study is to determine whether an experimental fluoridated dentifrice is effective in the treatment of dental caries

The study design is a randomised, split mouth, blind with respect to study analysts (microscopist, image grader) two treatment clinical study in 10 healthy participants with sound tooth enamel. The study will comprise of a screening visit, pre-baseline visit and 5 subsequent clinic visits. At the screening visit, participants will give consent to participate in the study. Medical history and concomitant medications will be recorded. Eligibility will be determined following an oral soft tissue (OST) examination and an evaluation of dentition exclusions. Two suitable anterior teeth will be identified for study assessments, these teeth must be at least one tooth apart in the mouth. Saliva samples will be collected from the participants at set points during the study to look at any changes in salivary pH.

Tooth hypersensitivity due to dental erosion is one of the most common problem related to swimming in improper pH chlorinated pools. Because the teeth are exposed to acidic water for a long time, which cause the loss of dental hard tissue. Tooth hypersensitivity can lead to a negative effect on daily life such as dietary selection, maintaining optimal dental hygiene and beauty aspects. It has been found that using mouthguard while swimming can prevent the teeth directly contact to chlorinated water, so it can protect tooth structure and decrease tooth hypersensitivity. Moreover, using mouthguard with viscous products can seal the gaps between mouthguard and teeth which can help to protect tooth structure and decrease dental hypersensitivity more effectively. At present, there are many desensitizing products such as toothpaste, mouthwash and chewing gum. Desensitizing toothpaste is the most common over-the-counter (OTC) materials in desensitizing. Many research has endorsed the properties of desensitizing toothpaste that can reduce tooth tissue loss and helps to reduce tooth hypersensitivity effectively. So it can be hypothesize that when use the combination of mouthguard with desensitizing toothpaste, it might have synergistic effect on reducing tooth hypersensitivity in swimmers.

Overweight and obesity are among the major chronic disorders of the 21st century and one of the fastest growing health problems worldwide. Obesity is accompanied by a state of low-grade inflammation which may contribute to the occurrence of diabetes mellitus, cardiovascular disease, hypertension, stroke, and certain cancers. Furthermore, obesity has been associated with oral health problems as hyposalivation, dental caries and periodontitis. The management and treatment of obesity is outlined in clinical guidelines from American Association of Clinical Endocrinologists/American College of Endocrinology and European Association for the Study of Obesity. The cornerstone is life-style modification programs aiming to reduce energy intake and increase physical activity, referred to as conservative treatment. All patients must undergo a thorough systematic work-up. The work-up concludes in a final multi-disciplinary meeting with a concrete individualized plan on how sustained weight-loss is to be achieved; either by a non-surgical or a surgical approach (Bariatric surgery). Periodontitis is cited to be the sixth most prevalent chronic condition globally. The mechanisms by which obesity affects the periodontal tissues is poorly understood, and the understanding of the key role of adipocytes in the inflammatory response to infections is crucial in comprehending how periodontal disease susceptibility may be modified in obese individuals. The main objectives of the present research project are to explore the association between obesity and oral diseases and further, to assess how weight changes following non-surgical and surgical interventions of obese patients may affect the cariological and periodontal health status. Four hundred patients referred to the Obesity Centre at Haukeland University Hospital, Norway will consecutively be screened and invited to participate in this prospective cohort study. At baseline, detailed medical and oral data will be obtained from health forms, questionnaires, clinical examinations, and by consulting the patient's care team. Following baseline examination, all patients will undergo a thorough systematic work-up consisting av interviews and consultations concluding in a final multi-disciplinary individualized non-surgical or surgical treatment plan on how sustained weight-loss can be achieved. New sets of medical, oral, and molecular data will be collected at 3-, 12- and 18-month following non-surgical/surgical interventions.

The purpose of this study is to compare and evaluate the ability of two European Union (EU) regulated gel to foam toothpaste formulations versus a non-fluoride toothpaste using a modified in-situ model of dental erosion and remineralization. A positive control i.e fluoride containing toothpaste marketed in EU will also be compared to non-fluoride toothpaste.
