Active clinical trials for "Dental Caries"

The fact that dental caries remains a major public health problem mandates that oral-health researchers explore new strategies for assessment of caries risk, as well as for caries prevention and management. Dental caries occurs when acids produced by bacterial glycolysis of dietary carbohydrates causes demineralization of the tooth enamel. A major focus of caries research has been on identifying and characterizing acid-generating bacteria and the mechanisms of acid resistance. The purpose of this study is to investigate over time the relationship between alkali production and caries.

Basic standard of care emphasis only tooth brushing and flossing without addressing individual pathological factors. For this reason, randomized controlled clinical trials on personalized caries management are needed to be able to compare the effectiveness of personalized caries management to basic standard of care. This is especially true in high caries risk populations and more so for young adults who stand to benefit the most from working towards a caries free adulthood.

Evaluate the effect of propolis extract mouthwash and pomegranate extract mouthwash on taste alteration, salivary pH and antibacterial activity against streptococcus mutans in high caries risk patients.

To compare the effect of a natural herbal licorice containing preventive measure alternative to chlorohexidine preventive measure to decrease the effect of streptococcus mutans.

This study evaluates the oxidative stress parameters in females with polycystic ovary syndrome (PCOS) and clinically healthy. Because of the fact that both oral disease included periodontitis and dental caries, and metabolic syndrome are associated with systemic inflammation, these two disorders may be linked through a common pathophysiologic pathway

Different phases of a woman's life are puberty, menses, pregnancy, and menopause. Menopause is one of the normal developmental stages in a woman's life, marks the permanent cessation of menstruation. It occurs due to irreversible changes in the hormones.The gradual variation and circulating sex hormones affect women's psychological balance and quality of life. The hormonal changes affect the reproductory system and affect the bone integrity and overall health of the individual. The only source of oocytes in women is an ovary. That is the primary source of oestrogens and progesterone, majorly the androgens. Therefore, various systemic health concerns like vasomotor symptoms, cardiovascular diseases, cancer, sexual problems, osteoporosis, and poor oral health

Preserving pulpal vitality is a major challenge when excavating deep caries lesions without severe symptomatology. Pulpal exposure alters success of the treatment (dropping from 93% for indirect pulp treatment with selective excavation to 11% for direct pulpotomy) and thus prognosis of dental organ and cost-effectiveness of the treatment. The preoperative x-ray is a complementary examination which allows to estimate the depth of the carious lesion. In clinical practice, it is currently difficult to accurately measure this depth on preoperative radiographs. This lack of precision leads to a decrease in the effective capacity of the operator to predict the risk of pulpal exposure. Their interpretation is considered imprecise and is not used as a diagnostic element. The aim of this study was to determine if the use of pre-operative retroalveolar radiographs can help to predict pulpal exposure risk.

Chewing, a movement that matures with experiences, has effects on the growth and development of the stomatognathic system. Tooth decay, which is known to have effects on chewing, can affect the jaw bone due to its indirect effect on the mechanical forces transmitted to the jaw bone. This study was aimed to evaluate the relationship between dental caries and jaw bone trabeculation during the growth and development processes in children by fractal dimension analysis method. 40 patients with deep-dentin caries / apical rarefying osteitis on the right or left side, 40 patients with deep-dentin caries / apical rarefying osteitis on either the right and left sides and 40 patients without deep-dentin caries / apical rarefying osteitis between 8-13 ages were randomly selected. Digital panoramic images of the selected patients were analyzed with fractal dimension analysis.

Background: Diabetes mellitus (DM) is well known for long-term complications to general and oral health. Periodontal disease has a bidirectional association with the development of type 2 diabetes (T2DM) (Mealey, 2006; Taylor, 2001; Demmer et el.,2008). However, current literature conflicts with regards to dental caries incidence in patients with T2DM (Sampaio, Mello and Alves, 2011). Objective: To investigate potential protective and risk factors for dental caries among T2DM with vitamin D and HbA1c using clinical, salivary and microbial analyses. Methods: This project is a case-control clinical study. The study will be conducted at Royal London Dental Hospital, Institute of Dentistry, Bart's Health NHS Trust, London, UK. This study will aim to recruit 182 participants in total with diabetes (type 2), aged ≥18 male or female and participants will be cross-matched with non-diabetes according to age and gender. Each participant will undergo a baseline screening for around 60 minutes where all the following assessments will be carried out; Caries risk assessment (CAMBRA), Plaque index, International Caries Detection and Assessment System (ICDAS) and Laser fluorescence evaluator (SOPRLIFE®, Acteon, France) and Oral behavioural and sociodemographic background will be collected. Prior to the clinical study, there will be a laboratory based study using extracted teeth. The aim of this ex-vivo study is to assess the autofluorescence variation in dental carious lesions and compare this with International Caries Detection and Assessment System (ICDAS).

This study investigates the benefit of using chlorhexidine gel as an antimicrobial agent in orthodontic patient to reduce caries risk and the possible consequential effect of this use on the orthodontic brackets used for the treatment. The investigators hypothesis is that chlorhexidine gel use can reduce caries risk in orthodontic patients with out causing damage to the bonded ceramic or metal orthodontic brackets.
