Filter by:This randomized clinical trial evaluated the clinical performance of class II resin composite restorations using bulk-fill high-viscosity ormocer versus methacrylate-based with or without a thin layer of bulk-fill low-viscosity (flowable) resin composite liners (BLRC) over 2 years. The null hypotheses in the study were as follows: (1) Different types of matrix structures (ormocer vs. methacrylate) have no effect on the marginal integrity of restorations; (2) A layer of bulk-fill resin compo-site liner of the same category would not affect the marginal or internal adaptation of restorations.
This study evaluated the effect of low-level laser therapy on postoperative pain and wound healing in children undergoing primary molar extractions 40children, 6-10 years of age, systemically healthy, and had atraumatic extraction indications of bilateral primary molar teeth were included in the study. A randomly selected tooth was extracted under local anesthesia in the first session. Only the clot formation on the socket was observed and photographed in the control group. Other group extractions were performed 2weeks later. The LLLT group was treated with a 980 nm wavelength Doctor Smile Wiser diode laser and photographed. Non-epithelialized surface measurements were performed with the ImageJ program. Pain assessment was performed with the Wong-Baker Pain Scale. Statistical analyses were performed with SPSS software.
Distal surfaces of second molars adjacent to wisdom teeth are always at risk for caries and external root resorption. The incidence of caries is high, especially in partially impacted third molars in mesioangular and horizontal positions. In this study, investigators aimed to examine the caries correlation in the distal second molar with the age, gender, side and DMFT scores of the participants.
This study is conducted A- To investigate that PRF loaded with osteopromotive pharmacological drug can be a great aid in implant rehabilitation, and whether it could be a replacement for the other high price bone graft materials or not. This will be done through: 1. Measuring bone changes around the implant by cone beam 2. Measuring change in bone density around the implants B- Evaluate the effect of statins on osteoblasts activity and expression of various osteogenic products in vitro.
Background: The Hall Technique (HT) is a non-invasive, easily applicable minimally invasive dentistry approach for managing dental caries in children. It involves placing a preformed metal crown over a tooth with decay, to seal it in and stop the decay from progressing. However, it alters the occlusion as no tooth substance is removed to make space for the crown. Objective: This study, aims to evaluate the effects of Hall Technique on occlusion in children, to assess whether there are any adverse effects on the temporomandibular joint and masseter muscles, related to changes on occlusion and to evaluate the children's perceptions of the crowns. Materials and Methods: A total of 37 children aged 5-9 years, who have not been treated with the Hall Technique previously and who have dentinal caries that did not reach the pulp (affecting the occlusal or the occluso-proximal surfaces) in their primary molars, will be invited to participate in the study. At the first visit, clinical examination will be carried out and intraoral impressions will be taken for pre-treatment evaluation. The occlusal vertical dimension of the teeth will be measured clinically with callipers. Temporomandibular joint and masseter muscles will be examined clinically. Then, the Hall Technique crown will be placed to treat the carious tooth, the impressions taken again, and measurements repeated. At one and three months following treatment with the crown, the participant will have the measurements repeated. The child and parent will complete a questionnaire after 3 months on their perception of the crown. In the data analysis, frequency, percentage, mean and standard deviation analyses will be used for demographic data and description of the clinical data. In numerical data analysis, t-test or Mann-Whitney U test will be used according to the data distribution. Geomagic software will be used to analyse sequential study models of the teeth to measure relative changes in the tooth positions over time.
Background: Maintaining biosafety in dental practice requires an efficient elimination of aerosols produced during dental treatment. The objective of this research was to assess the quantity of aerosols and aerobic bacteria present in the air during the treatment of caries. Methods: This study was divided into two groups based on the caries treatment method involving 60 patients with 60 m olar teeth (n=60) in the mandible. Group 1 (n=30) received a conventional dental turbine W&H Synea TA-98LC (W&H, Bürmoos, Austria), while Group 2 (n=30) received an Er:YAG laser (LightWalker, Fotona, Slovenia). Measurements of aerosol particles between 0.3 - 10.0 μm near the operator's mouth were taken using the PC200 laser particle counter (Trotec GmbH, Schwerin, Germany). The number of aerobic bacteria in the air was determined using 60 micro-biological plates with a microbiological medium (Columbia Agar with 5% Sheep Blood) and the sedimentation method. A control group G3 was established to measure the initial aero-sol level and the initial total number of bacteria CFUs (colony-forming units) before each treatment.
Inhibition of streptococcus mutans can be effective to prevent caries in high caries-risk children. The aim of the study is to evaluate the effect of Novamin on streptococcus mutans in the plaque of high caries-risk children.
This study aimed to investigate the effect of using a loupe and dental operating microscope with different magnifications on the success of class II direct composite restorations.
The present cross-sectional observational study was conducted after the university ethical committee approved the research (NU/CEC/2020/0339). This study included 376 adults in the age group of 18-40Yrs. The patient information sheet briefed the study details and usage of salivary samples. Informed consent was obtained from participants. Healthy individuals free of associated systemic conditions, individuals not under any nutritional supplementation were included in the study, and lactating mothers, smokers, and menopausal women were excluded
This study aims to determine the effectiveness of an intraoral scanner with near-infrared imaging (NIRI) for the diagnosis of proximal caries.
