Filter by:All ceramic crowns are indicated in case of mild to moderate discoloration, restoration of traumatized or fractured teeth and abnormal tooth anatomy. The success of dental restorations is determined by four main factors: biocompatibility, aesthetic value, resistance to fracture and marginal adaptation. . An inadequate marginal fit may compromise the longevity of the restoration since cement film exposure to the oral environment can lead to its dissolution . . Polyetheretherketone (PEEK) is a polymer that has many potentials uses in dentistry. Polyetheretherketone (PEEK) can be used to support fixed dental prostheses. However, information about physio mechanical characterization is still scarce. Aim of the study: - The aim of this study is to evaluate the internal fit of milled BioHPP PEEK-based versus zirconia-based single crowns.
Removal of infected dentin contaminated with bacteria and remaining affected dentin detected as firm is the conventional strategy for the management of cavitated caries lesions. Recently, this strategy is termed as selective removal to firm dentin (SRFD) and seems to increase the potential risk of pulp exposure or loss of pulp vitality for deep caries lesions radiographically extending ¾ of dentin tissue. Alternatively, selective removal to soft dentine (SRSD) that refers to removal of caries tissue at the periphery of the cavity to firm dentin and remaining caries tissue detected as soft or leathery in proximity with the pulp might be a less invasive excavation method for deep caries lesions to maintain pulpal health. However, information on clinical advantages or disadvantages of SRSD and SRFD excavation methods is sparse and mostly rely on studies conducted for primary teeth. Moreover, clinical trials are needed to demonstrate the combined effect of carious removal strategies and calcium silicate-based materials. The aim of this study is comparison of clinical success rates of SRSD and SRFD techniques in posterior deep caries lesions. The primary outcome of the study is comparison of clinical success of SRSD and SRFD techniques by clinical and radiographic examination after 3 months, 6 months, 1 year and 2 years. The secondary outcome of the study is to investigate whether or not calcium silicate-based materials have an effect on the success rate of the treatment.
The objectives of this study are i) to monitor the oral health of young people over a period of one year and ii) to assess the ability of a new intraoral scanner combining fluorescence with 3D imaging to detect and monitor changes in the dental hard tissues in vivo. The working hypotheses of this study are that i) the monitoring of oral health will benefit from using a new intraoral scanner combining fluorescence with 3D imaging and ii) the new intraoral scanner combining fluorescence with 3D imaging will aid dentists to identify changes in the dental hard tissues at earlier stages than the traditional diagnostic methods (i.e. visual-tactile, radiographic methods).
Decay is a multifactorial infective degenerative disease of hard dental tissues, caused by Streptococcus mutans and Lactobacillus forming the bacterial biofilm of teeth surfaces. Decays generally evolve in fissures and pits of secondary molars. Pits and fissure sealants prevent decays if performed in two years from eruption. Ozone has bactericidal effect and remineralizing capacity on enamel. The aim of this study is to assess the effectiveness of ozone application before sealants in increasing their duration in time.
This study will follow a randomised, double-blind, cross-over design. Participants will use mouth rinses containing plant extracts and/or fluoride, as well as a mouth rinse containing only water (placebo). They will use oral appliances containing sterilized enamel and dentine slabs, which will be later collected for analyses. The cross-over design will allow participants to use all rinses, allowing for a comparison between the rinses within each individual.
66 Participants will be divided into three groups according to the tested regimen (A), where (A1) represents participants will be exposed to regimen including dual zinc plus arginine based toothpaste (Colgate total), (A2) represents participants will be exposed to regimen including zinc based toothpaste (Crest complete) and (A3) represents control group where participants will be used fluoride based toothpaste (Signal). The study will be carried over a period of one year, assessment of cariogram will be done in two visits: first visit (baseline: T0) and second visit (after 3 months: T3) . In addition assessment of DMF scores will be done in four visits: first visit (baseline: T0), second visit (after 3 months: T3), third visit (after 6 months: T6) and final visit (after 12 months: T12) to obtain the required data
66 Participants will be divided into three groups according to the tested regimen (A), where (A1) represents participants exposed to fluoride toothpaste, (A2) represents participants exposed to regimen including fluoride toothpaste and chlorhexidine mouthwash and (A3) represents participants exposed to regimen including fluoride toothpaste, chlorhexidine mouthwash and MI fluoride varnish. The study will be carried over a period of one year, assessment of cariogram will be done in two visits: first visit (baseline: T0) and second visit (after 3 months: T2).

Successful restoration of cavities in primary molars can be considered challenging. It is different from restoring cavities in permanent molars because factors such as the level of co-operation of the child and the handling properties and setting time of the restorative material will have some influence on the success rate of the restoration. The ideal requirements that a filling material should possess include that it bears the occlusal force, withstands the acidic and bacterial attack, survives in the oral environment in addition to being biocompatible with the oral tissues. In an attempt to achieve this idealism, a new class of restorative materials known as "bioactive materials" has been developed. The concept of bioactive materials was introduced in 1969 and later defined as "one that elicits a specific biological response at the interface of the material which results in the formation of a bond between tissues and the material." An example of bioactive materials is ACTIVA™ BioACTIVE (Pulpdent, USA). These materials are ionic composite resins which combine the biocompatibility, chemical bond and the ability to release fluoride of glass ionomers with the mechanical properties, esthetic and durability of composite resins. Compomer is widely accepted as a standard restorative material for primary dentition for Class I and II cavities. Its range of success rate in Class II restorations in primary molars is 78-96%. Many randomized clinical trials have reported comparable clinical performance to composite resin with respect to color matching, marginal discoloration, anatomical form, marginal integrity and secondary caries. In comparison to glass ionomer and Resin Modified Glass Ionomer, compomers tend to have better physical properties in the primary dentition. However, their cariostatic properties didn't differ significantly from those materials.
randomized clinical trial to evaluate caries regression, the change in colour and mineral content of the demineralized enamel after treatment with Remin Pro Forte paste (fluoride, hydroxyapatite, xylitol, ginger, and curcuma) and Remin pro cream which contains (fluoride, hydroxyapatite, xylitol) remineralizing agents with the null hypothesis that Remin Pro forte will have the same clinical performance as Remin Pro in remineralizing white spot lesions post-orthodontic treatment.
The School of Dentistry is seeking to determine whether viable microorganisms remain within tooth structure after conventional, mechanical removal of areas of tooth decay, prior to placement or replacement of tooth restorations (fillings). The long-term goal of the work is to decrease the failure rate, and therefore increase the longevity, of tooth restorations (fillings) in human patients and populations.
