Filter by:Early childhood caries (ECC) is a global health problem that causes pain and infection to the children affected. It is a common disease among preschool children in Hong Kong. There is a great need to improve at-home ECC preventive measures through oral health promotional activities as early as possible to parents. The investigators will propose a 4-year randomized controlled trial of family-centered oral health promotion for new parents which aims to increase the proportion of parents brushing their infants' teeth at 1 year, establishing proper feeding and dietary habits, reducing the transfer of MS from the parents to their infants and then reducing the risk of ECC of the children at 3 years. The investigators also aim to improve the oral hygiene status of the new parents and prevention of oral diseases among themselves. First-time expectant mothers and their husbands will be recruited. The recruited families will be randomly allocated to the test and control groups. In the test group, personal hygiene instruction (OHI) for the expectant mothers and their husbands together with oral health education materials on infant's tooth development and eruption, establishment of proper feeding, dietary and toothbrushing habits will be given before the delivery of the new born babies. Reinforcement of OHI and demonstrations on how to clean the infant's oral cavities and perform toothbrushing will be delivered after the babies are born. Comprehensive data will be collected from the mothers, fathers and the infants in both the test and control groups at different time points through dental examination, biological testing and questionnaire survey. The CONSORT statement will be strictly followed when conducting the clinical trial, analyzing the data and reporting the results. It is anticipated that the effectiveness of oral health promotion starting at the pregnancy period and for both expecting mothers and their husbands will be greater in preventing the infants from developing ECC. Furthermore, establishing good oral health care habits will have long term benefits, helping safeguard the oral health of the children as they grow and the family as a whole. This study will also provide much needed evidence for the further development of oral health policies and oral health promotion programmes in Hong Kong; specifically how these can be integrated into family health education so as to achieve a higher effectiveness. This will contribute significantly to the improvement of oral health in the population of Hong Kong.
The aim of the present study was to study if there are interactions and reduced clinical effect between chlorhexidine and fluoride when they are combined in the same mouthrinse.
The aim of this study is to assess the clinical effect of aPDT on deep caries in permanent teeth. Half of the deep caries will receive aPDT disinfect in restorative treatment procedure, while the other half will receive sodium 0.9% saline in restorative treatment procedure.
The aim of this study is to determine the beneficial effect of mouth rinses, both topical analgesic and saline regimens as an adjuvant therapy in the presence of standard prescription of post-operative pain killers on the progress of socket healing following routine dental extraction.
This study aims to compare the ability of different regenerative protocols in the treatment of mature necrotic
The aim of this study is to compare the effect of color change between remineralizing agent and guided enamel regeneration in treatment of white spot lesion after orthodontic treatments
The aim of this study is to evaluate the addition of new technology of resin modified glass-ionomer in comparison to resin infiltration in treating post-orthodontic white spot lesions; both applies into the same patient's mouth; to reveal which material will have more clinical satisfactory performance inside the oral cavity and to overcome the high expensive cost in treating such clinical cases
The proposed study is a pre- /post-implementation study in a pediatric practice with a control practice designed to test the feasibility and effectiveness of an electronic screening and service delivery tool for three modifiable health risk factors in pediatrics: parental tobacco use, sugar-sweetened beverages consumption, and poor dental care
This project aims to evaluate the effect of antimicrobial photodynamic therapy (aPDT) in deep carious lesions. This study was approved by the Research Ethics Committee and was conducted on 53 patients between 3 and 12 years. Patients included in the study should have at least one primary molar or permanent with deep active caries and limited occlusal/proximal surfaces involving beyond the inner half of dentin. The investigators considered from exclusion criteria children whose parents refuse to sign the informed consent document; children who do not cooperate with the clinical examination/treatment; children with syndromes or chronic systemic diseases; teeth with painful symptoms consistent with irreversible pulpitis or mobility; periodontal changes; roots with pathological resorption; cases of primary teeth roots in an advanced stage of physiological resorption and patients that have made the use of any antibiotics during the study period or within three months prior to its beginning. The treatments were carried out after local anesthesia and isolation of the operative field with a rubber dam. The removal of carious dentin surface demineralized necrotic and not subject to remineralization was held with the drill at low rpm under cooling with sterile saline. The removal of decayed tissue will start with the side walls and later on the pulp wall. After this time the intervention with aPDT using 0.01% methylene blue as photosensitizer will be held. Finally, the cavity is restored with an adhesive and composite resin system. To collect data for the first outcome the dentin samples were collected from 23 participants with the help of spoon sterile dentine in two stages: C1 after digging and C2 after aPDT. The microbiological analyzes will be conducted by counting colony-forming units (CFU / mg of carious dentin), blindly from coded samples. The viability of microorganisms will be evaluated in the following culture media: Brain Heart Infusion agar for the feasibility of total microorganisms; CHROMagar candida to Candida genus; Mitis Salaviarius agar with the addition of bacitracin 0.2 U/mL, sucrose and glucose to Streptococcus mutans; Mitis Salivarius agar to total Streptococcus; Rogosa Agar to Lactobacillus spp. and enterococcosel for Enterococcus genus. The reproducibility of the counting method will be verified between triplicates. Microbiological data will be evaluated with appropriate statistical tests with a level of 5%. For the second outcome, a randomized clinical trial was designed. Primary molars of 30 patients (mean age 6.15 years) with deep caries lesions without signs and symptoms of pulpal involvement were selected. A total of 64 teeth were randomly divided into groups G1 (SCR, 32 teeth) and G2 (SCR + aPDT, 32 teeth) for treatment, restored with composite and evaluated after a week (T0), 6 months (T1), and 12 months (T2) according to the criteria of FDI. Groups were compared using the Rao-Scott chi-squared test and the logistic regression analysis for complex designs to ac- count for multiple observations per subject (alpha = 0.05). All participants answered a questionaire to detect the impact on Oral Health-related quality of life(OHRQoL) before and 3 months after the treatment. Based on this project we prove the clinical efficacy of aPDT using 0.01% methylene blue as an adjunct in reducing microorganisms from the interior of deep carious lesions and we contributed to demonstrate the clinical and radiographic success in a follow-up from 12 months providing additional support aPDT used as an adjunct to SCR on the longevity of composite resin restorations in primary molars. A low laser therapy (aPDT) with SCR did not influence negatively OHRQoL. In the practice of pediatric dentistry, this conservative dental treatment improved the OHRQoL after 3 months of follow up.
In Germany about 5 to 20% of children suffer from early childhood caries (ECC). Preceding results of eye-tracking-studies on the perception of patients with unilateral cleft and patients with severe orthognathic malocclusion let us assume that caries and missing teeth might influence the observer's focus. The aim of this study is to test the hypothesis that the faces of patients with ECC and patients with signs of dental treatment (crown, gap etc.) are contemplated differently from and assessed more negatively than healthy patients. Particular attention should be paid to potential differences between the findings of the two observer-groups (medical laypersons/ dental students).
