Filter by:Deep margin elevation (DME) is a non-invasive restorative technique to relocate the deep cervical margin to a supragingival position using resin composite. This retrospective multicenter practice-based study will assess the long-term clinical performance and periodontal health of teeth restored with CAD-CAM crowns with or without DME. Patients who will receive CAD-CAM lithium disilicate (LD) crowns with or without DME between 2013 and 2023 at multiple private practices will be included. When indicated, DME will be performed using resin-based restoration. Clinical assessment of the crowns and supporting periodontal structures will be performed following the modified United States Public Health Service (USPHS) criteria. Intra-oral photographs, periapical and bitewing radiographs will be taken for further assessment by three evaluators. Kaplan Meier survival analyses will be performed.
The goal of this randomized clinical trial is to test the effect orally administration of Probiotics based on Lactobacillus rhamnosus LR04 and Lactobacillus plantarum LP14 as adjuvant in caries prevention in subjects who can not properly perform oral hygiene procedures. The main questions it aims to answer are: - QUESTION 1: orally administered probiotics based on the previous strains could represent a useful tool in support of special needs patients in tooth decay prevention? - QUESTION 2: orally administered probiotics based on the previous strains could ameliorate salivary pH management? Partecipants in the test group will take the test probiotic for 90 days in adjunction of the routinary oral hygiene procedures. Partecipants in the positive controlled group will take the placebo for 90 days in adjunction of the routinary oral hygiene procedures. Partecipants in the negative control group will perform only the routinary oral hygiene procedures. Researchers will compare 3 groups to see if orally administered probiotics based on L. rhamnosus and L. plantarum may help in the management of clinical status and salivary pH levels.
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.
Sealants effectively arrest non-cavitated caries lesions on the fully erupted occlusal surface of permanent teeth. However, the clinical effectiveness of sealants is uncertain in preventing occlusal caries lesions in partially erupted permanent molars. This study aims to evaluate the progression of caries, the degree of retention, survival rate, and quality of the remnant after applying conventional total-etch resinous sealant and self-etch sealant in erupting molars.
Aim of the study: The aim of this RCT is to evaluate CAD/CAM onlays fabricated by subtractive technique (brilliant crios) versus additive technique (varseosmile crown plus material), in terms of clinical functional evaluation following the FDI criteria and three-dimensional digital evaluation of the marginal and internal fit by triple scan protocol. Materials and methods: A total of 30 patients will be enrolled in the clinical trial following the eligibility criteria. Then, the patients will be randomly allocated to receive either 3D printed onlays or milled ones. A blinded operator will prepare a standardized cavity for the restoration and an impression will be performed. After designing the restoration on the Exocad software, A dentist not involved in the clinical part of the study will receive the STL file of the design and envelopes containing the information necessary only to manufacture the restorations (tooth numbers and restorative materials) to proceed with either the milling or printing procedures. Try in and cementation procedures will be similarly performed for both groups by a blinded operator. Finally, the marginal and internal fit will be evaluated by using the triple scan protocol for digital 3D assessment. Also, a baseline, six months and 12 months assessments will be performed by a blinded examiner, not involved in the clinical part for assessing the functional clinical performance of the re3stprations using the FDI criteria. Finally, the data will be statistically analyzed.
In this study the objective is to establish in depth knowledge about adolescents' oral health characteristics, - practices and - needs. Further, we want to evaluate whether adolescents' caries status can be associated with existing socio-economic inequality, emotional health and lifestyle factors. The main question[s] it aims to answer are: 1. What is the caries status (i.e. prevalence, increment at different timepoints and characteristics) among adolescents in Trøndelag? - What is the caries prevalence in different age groups? - Is there any difference in caries prevalence linked to specific age groups, gender or urban versus rural areas? - Are approximal tooth surfaces especially prone to the development of new caries lesions? - Is the caries increment from 12 to 20 years a continuous process or are there high-risk periods within this timespan? - How is the prevalence of enamel caries? Is enamel caries more prevalent in younger age groups than in older age groups? 2. What are the patterns of recall intervals and non-attendance in different age groups, among adolescents in Trøndelag? - What are the attendance rates and prevalence of non-attendance at dental appointments in different age groups? - What is the recall interval between regular follow-up dental visits? - Are there any recall or attendance characteristics linked to age group, gender or urban versus rural areas? 3. What factors (i.e. oral health behaviours, socioeconomic-, lifestyle- and parental factors) are associated with caries among Norwegian adolescents? - How are the oral health behaviours (i.e. dietary- and oral hygiene habits, attendance to dental care) among adolescents, and are there any shared oral health behavioural challenges? - Is the caries prevalence linked to life challenges (mental illness, alcohol/drug use and chronic diseases)? - To what degree are oral health behaviours associated with caries among adolescents? - Is there any association between media screen time and oral health behaviours, and cariesstatus? - Is there any association between physical activity, sport participation and oral health behaviours, and caries status? - What are the associations between socioeconomic factors (study program, birth- and migration background, and parental income, education and employment) and oral health behaviours, and caries status? For research question 1 and 2, the sample will be adolescents aged 12-20 years living in Trøndelag county in the time period 2008-2020, (n≈115000, Statistics Norway, SSB). Data will be extracted from dental health records in the public dental service (Den offentlige tannhelsetjenesten, Trøndelag Fylkeskommune). The public dental service annually reports caries prevalence for 12- and 18-year-olds, Statistics Norway, SSB (Figure 1). However, the knowledge is modest about the caries development within the six years from 12 to 18 years of age. Further, the public dental service offers subsidised dental care to 19- and 20-year-olds. Extracting data from dental health records in the public dental service will give us the opportunity to explore the caries increment at multiple timepoints, and attendance rates at dental appointments throughout the teenage period from 12 to 20 years of age. For research question 3, the sample will be adolescents (n≈8000) and their parents that participated in the fourth survey of The Trøndelag Health Study (HUNT4) in 2017-2019. Self-reported questionnaire data will be linked to data from dental health records in the public dental service.
This study aims to determine the effectiveness of an intraoral scanner with near-infrared imaging (NIRI) for the diagnosis of proximal caries.
he study was designed as a double-blind three-parallel-group randomized controlled trial, in which the evaluators and a researcher, not involved in the evaluation process, was responsible for the randomization process, were masked to the group assignment. The study will be carried out at 2 schools of the Metropolitan Area of Buenos Aires where school programs are developed by the Department of Preventive and Community Dentistry of the University of Buenos Aires, and that present homogeneous characteristics in terms of social risk. The children (n=244) attending those primary schools will be the population object of the trial. Clinical examinations Each child will go under a clinical examination to determine dental status according to the ICDAS II criteria (Pitts, 2005) and the Caries Treatment Need Index (CTNI). Intervention Children will be divided into three different groups according to the mode of treatment: - NaF varnish group (NaFV) Professional application of 5% NaF varnish twice a year pH 7 (ClinPro White Varnish®) according to manufacturer's instructions. - APF in tray Group (APFt) Professional application of APF 1.23% twice a year pH 3.5 (Klepp®) with tray according to manufacturer's instructions - APF in toothbrush group (APFtbru) Professional application of APF 1.23% twice a year pH 3.5 (Klepp®) with toothbrush 2 minutes brushing according to manufacturer's instructions. Dental examination and Monitoring Observations and clinical examinations will be conducted at schools. After 12 and 24 months, the clinical examination will be repeated to assess the dental status of schoolchildren following the same criteria described. The presence of new caries lesions will be taken as a dependent variable. So sound surfaces on baseline will be observed for 24 months.
