This study is about the assessment of two oral telemedecine tools compared to an intra oral clinical examination used as a reference among elderly persons living in nursing home. Our hyposthesis is that the diagnostic performance of the two devices will be similar. The main goal of the study is to assess the performances of two intra-oral cameras compared to an intra oral clinical examination to detect at least one decayed tooth. The secondary objectives of this study are : At patient's level: 1. To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) at least one filled tooth, (ii) at least one missing tooth, (iii) gingivitis, (iv) an abscess, (v) dental plaque and (vi) calculous 2. To assess the concordance between each intra oral cameras and the intra oral clinical examination in the evaluation of the number (i) of decayed teeth, (ii) filled teeth and (iii) missing tooth 3. From video acquisitions of each intra oral cameras, to assess the inter-observer concordance for the diagnostic of each dental pathologies (presence of at least one decayed tooth, filled or missing) and periodontal (presence of gingivitis, abscess, dental plaque or scale) 4. From video acquisitions of each intra oral cameras, to assess the inter-observer agreement of the number of teeth: (i) decayed, (ii) filled and (ii) missing At tooth level : 5. To assess the performances of two intra-oral cameras types compared to an intra oral clinical examination for detecting each of the following conditions: (i) a cavity, (ii) a filled tooth and (iii) missing tooth In all patients : 6. To assess patient's feelings about the use of each intra oral cameras 7. To compare the time required for video acquisitions between each of intra oral cameras For patients with dental or periodontal pathologies observed during the intra oral examination: 8 To assess, 2 months after initial evaluation, the proportion of patients attended dental or periodontal care and for which an appointment with a dentist has been scheduled
In Hong Kong, approximately half of the kindergarten children have dental caries (tooth decay) and the majority (>90%) of the decayed teeth were left untreated. There is a need to generate clinical evidence for designing an effective dental caries prevention programme for preschool children in Hong Kong. The objective of this study is to compare the effectiveness of 38% silver diamine fluoride (SDF), 5% sodium fluoride (NaF) varnish and placebo control in preventing dentine cavitated caries in primary molars in preschool children when applied semi-annually over 30 months. Around 770 preschool children attending Grade 1 in selected kindergartens will be invited to participate in this clinical trial. Only generally healthy children with written parental consent will be included. At baseline, clinical examination will be conducted in the kindergarten to assess the tooth and oral hygiene status of the included children. After the baseline examination, the children will be randomly assigned to one of the following three study groups and the occlusal (biting) surfaces of their primary molars will receive the corresponding interventions: Group A - semi-annual topical application of 38% SDF; Group B - semi-annual application of 5% NaF varnish; and Group C - semi-annual application of placebo control with tonic water. Clinical examination of the study teeth in the children will be conducted every 6 months after the baseline to assess the outcome of the intervention. The primary outcome is whether cavitated dentine caries lesion is found in the treated occlusal tooth surface. The null hypothesis tested is that there is no difference in the effectiveness of semi-annual application of 38% SDF and that of 5% NaF varnish versus placebo control in preventing dentin occlusal caries in primary molars of preschool children. The results of the proposed study will provide evidence to strengthen or refute the recommendation regarding the use of SDF for preventing occlusal caries in primary molars. The study findings will be valuable for guiding decision-making among dental practitioners and health policymakers on whether SDF should be complemented in a school-based caries prevention program.
The present study is a double-blinded randomized clinical trial with a duration of 28 days. 80 orally and systemically healthy participant will be allocated in the test (probiotic) and the control (placebo) group at baseline. The intervention is sugar stress, which will be applied at baseline and continue through day 14, followed by 14 days without sugar stress. Clinical measurements and sampling will be performed at baseline, day 14 and day 28 Primary endpoint: Changes in microbial composition. Secondary endpoints: Changes in clinical and immunological parameters
Dental caries is highly prevalent across the globe including Pakistan and is associated with tooth loss, malocclusion and temporomandibular joint problems and sometimes may cause life threatening infections. Streptococcus mutans is considered to be one of the major pathogen responsible for the development of dental caries. As treatment of dental carries is quite expensive, main focus is on the prevention of dental carries. Chlorhexidine is the gold standard mouthwash used for the prevention of dental carries but its use has been associated with certain side effects including staining of teeth, burning sensation and a bitter taste in the oral cavity. Many populations use medicinal plants as traditional or alternative treatments for various ailments due to their better safety profiles, health beneficial effects, lower cost and easy availability. Among the plant species used for medicinal purposes are those of the genus Morus. Its most commonly used species are Morus alba, rubra and nigra that have also shown antimicrobial properties against various infections in addition to other health promoting effects. Moreover, morus alba fruit has not been evaluated for its antimicrobial activity against oral pathogens including streptococcus mutans. The purpose of this study is to evaluate the antimicrobial properties against salivary streptococcus mutans and alteration of pH in the saliva of patients with dental caries before and after the use of chlorhexidine and morus alba fruit extract mouthwashes. This study is double blinded randomised clinical trial. Sample size is calculated according to open Epi calculator and came out as 1 in each group. We will take sample size as 120 and the sampling technique will be non-probability consecutive sampling. Morus alba extract preparation will be done in the Botany department of Lasbella University of Agriculture, Water and Marine Sciences (LUAWMS) Balochistan. According to inclusion criteria and after obtaining informed consents, samples of saliva of the individuals of 18-40 year of both genders will be collected from the OPD of Dentistry department, Civil hospital Uthal Balochistan at the beginning of the study and two weeks after the treatments. The total 120 subjects will be equally divided into three groups, 40 participants in each group (A, B and C). The subjects in group A will be given chlorhexidine mouthwash and the subjects in group B and C will be given 20% and 30% aqueous extracts of morus alba fruit in the form of mouthwashes respectively. The samples of saliva will be analysed for S.mutans counts and pH levels at baseline and 15 days after the use of respective mouthwash. Culture procedure for S.mutans count will be Dilution and Spread plate technique.

Fluoride foam and fluoride varnish are effectiveness in prevention deciduous dental caries. However, the relative clinical efficacy and cost-effectiveness of these two interventions are uncertain. This study aims to evaluate the relative clinical effectiveness and cost-effectiveness of fluoride foam and fluoride varnish in preventing dental caries in the primary teeth of preschool children with high caries risk.
Objective: To evaluate the immediate clinical performance using FDI criteria in occlusal and proximal lesions restored with dual polymerization bulkfill composite resin. Materials and methods: Experimental, clinical, controlled, randomized, double-blind study. For the evaluation of Fill-up! (FU) will be clinically compared to the control groups of a conventional Tetric N-Ceram (TB) RBK and Filtek z350 (z350) conventional composite resin. The adhesive process will be carried out under absolute isolation, of selective etching of 37% orthophosphoric acid enamel before applying the respective adhesive according to the trademark of the composite resins. The evaluation will be to 30 days, 6, 12, 18 and 24 months using the modified FDI criteria of postoperative sensitivity, marginal staining, color, marginal adaptation and anatomy, being 1: Excellent, 2: Good, 3: Fair, 4: unsatisfactory and 5: unacceptable. The non-parametric Kruskal Wallis test and Friedman (95% significance) used to compare the criteria.
The aim of the study is to assess the effectiveness of 38% Silver Diamine Fluoride (SDF) solution and to determine if it is superior to 5% NaF varnish in arresting carious lesions in the primary teeth of young children attending general dental clinic, Universiti Teknologi Mara. Hypothesis: Topical application of a 38% SDF solution on the primary teeth is superior to that of a 5% NaF varnish in arresting caries lesions in children at 3-months follow-up An intervention study is planned to compare the effectiveness of 38% SDF and 5% NaF in arresting caries lesions in primary teeth of 3-8 years old children attending general dental clinic, Universiti Teknologi Mara. The sample size needed (considering a 20% dropout rate) is 66 participants in each group. In addition, this study also aims to determine the demographic background, oral health-related habits, oral health-related quality of life of the participants and the parents acceptance on SDF treatment towards their child.
