Metallic restoration components such as dental subgingival implant abutments are exposed to pH changes and different ions while in contact with saliva. The aim of the study was to evaluate the corrosion resistance of titanium dental implant abutments and to compare and contrast the surface characteristics of these alloys before and after corrosion. The corrosion examination (Ecorr, jcorr, OCP, polarization curve) of two implant abutments (TiDesign EV, Astra Tech, Dentsply, York, PA, USA; Individual Titanium Abutment, Apollo Implants Components, Pabianice, Poland) was performed in 0.9% NaCl and 5% HCl. Moreover, specimens were investigated using SEM-EDS before and after the corrosion test. The value of jcorr in NaCl was higher for Astra (34.2 × 10−8 ± 2.5 × 10−8 A/cm2) than for Apollo (8.8 × 10−8 ± 2.5 × 10−8 A/cm2). Whereas, in HCl, the opposite relationship was observed (Astra 2.9 × 1...

The appliance position is planned and fixed on a plaster model and then transferred into the oral cavity. Indirect bonding is a precise and time-saving technique of bracket placement, growing in popularity in recent years. It provides a combination of great precision with time efficiency. The fundaments of the indirect bonding technique are presented here. From the first clinical trial conducted almost fifty years ago, the method has evolved; the progress that has been made is described. Modern technologies involving computer scanning and manufacturing have led to great precision in bracket placement. Digital innovations such as rapid prototyping and stereolithography open up a new avenue of research and represent the next steps in indirect technique development. Individual 3D transfers are convenient in difficult clinical cases and can improve the effectiveness of the procedure, reduce the number of technical stages and reduce total chairside time. This paper also summarizes the advancement in adhesive materials, including an overview of advantages and disadvantages of different types of bonding resins and of the mean shear bond strength (SBS) achieved in the indirect procedure.

The properties and clinical performances of four calcium-silicate cements (ProRoot MTA, MTA Angelus, RetroMTA, Biodentine), a light-cured calcium silicate-based material (TheraCal LC) and an enhanced resin-modified glass-ionomer (ACTIVA BioACTIVE) are widely discussed. A correlation of in vitro and in vivo data revealed that, currently, the most validated material for pulp capping procedures is still MTA. Despite Biodentine's superiority in relatively easier manipulation, competitive pricing and predictable clinical outcome, more long-term clinical studies on Biodentine as a pulp capping agent are needed. According to available research, there is also insufficient evidence to support the use of TheraCal LC or ACTIVA BioACTIVE BASE/LINER in vital pulp therapy.

The displacement of the articular disc with reduction in the temporomandibular joints (TMJ) is a disorder with complex and multifactorial aetiology requiring adequate treatment. According to the authors of many studies, increased tension and a direct attachment of muscle fibers of the upper part of the lateral pterygoid muscle to the articular disc increase the likelihood of the disorder. The treatment of choice is conservative, including increasingly frequent intramuscular injections of botulinum toxin. By blocking the secretion of acetylcholine in the neuromuscular plate Botox causes a reverse tension reduction or complete paralysis of the upper part of the lateral pterygoid muscle. In consequence, it may lead to the return of the disk to the right place in the TMJ with the simultaneous decrease of clinical symptoms in patients. Aim. To perform a systematic review of treatments for the anterior articular disc displacement using botulinum toxin. Material and Methods: For the preparation work, the available databases: PubMed, Google Scholar, OVID and Embase were used. Original papers published in the last twenty years, in Polish and English, using the key words: botulinum toxin, the displacement of the articular disc, were searched. Results and conclusions. The current state of knowledge and results of studies in the literature suggest that botulinum toxin is suitable for the treatment of anterior articular disc displacement.

This article aimed to assess the influence of different sodium ascorbate (SA) presentations (liquid, gel, and semi-gel) on the composite resin–enamel bond strength after a bleaching protocol. Sound human anterior teeth were collected, cleaned, prepared for a bond strength test, and randomly allocated into groups according to the bonding procedure. Group 1 acted as a control, without bleaching treatment, and without applying an antioxidant agent. In groups 2–6, specimens were bleached using 10% carbamide peroxide. In groups 3, 4 and 5, 10% wt% SA was applied for 10 min as an antioxidant in the form of a liquid, gel, and semi-gel, respectively. In group 6, samples were bleached and immersed in fresh human saliva for 14 days. After the bleaching process, the materials were restored by means of an adhesive system and a resin composite materia...

The mental foramen (MF) is a bilateral opening localized on an anterior surface of the mandible. A precise location as well as well-defined shape, size, and number of the MF is crucial for different clinical dental procedures. The aim of this study was to determine a size and location of the MF in relation to the lower teeth using the cone-beam computed tomography (CBCT) study. Material and Methods. In a group of 201 patients (106 males and 95 females) the CBCT images were performed using the GX CB-500 device (Gendex, USA). Results. No significant differences in values of the horizontal (H) and vertical (V) diameters as well as the H:V ratio on both sides in relation to the age of participants were found. In males both average values of a horizontal diameter (p=0.031) and vertical diameter (p=0.001) were significantly higher on the right side than in the female subgroup, whereas on the left side only an average value of a vertical diameter was significantly higher in m...

Its' prevalence ranges from 25% to 72% in the first 24 hours after treatment. There are several factors that affect post-operative pain occurrence. They are associated with the patient, canal preparation technique, and parameters of applied files. The apical foramen widening and apical extrusion of debris are the most important direct causes of post-operative pain. Clockwise or counterclockwise motion of the file may support the extraction of dentinal chips and extrusion of debris in the periapical area. Both incidence and intensity of pain are significantly lower after preparation with rotary instruments in comparison to reciprocating systems and hand files. Cross-section and taper of the instrument affect the amount of space for debris and efficiency of its' removal. Moreover, reduction of cross-section area and number of cutting edges are advantageous. Preparation of the apical part of root canal determines the risk of physiological foramen transportation or widening (over-preparation), resulting in increased incidence of post-operative pain. There are significant discrepancies related to the number of visits on treatment and its' influence on discussed ailment occurrence. Singlevisit RCT provides both higher healing rate and more often discussed ailment occurrence than multi-visit one.

Among numerous factors affecting adhesion, the type of bracket and preparation of the tooth’s surface are crucial. The aim of this study was to compare the shear bond strength (SBS) of metal and ceramic brackets to the enamel’s surface using direct bonding. Forty extracted human premolars were divided into four groups according to the etching method (etch-and-rinse and self-etch) and bracket type. The SBS and adhesive remnant index (ARI) were determined. The ceramic brackets achieved the highest SBS values both in the self-etch (SE) and etch-and-rinse (ER) protocols. Higher SBS values for ceramic and metallic brackets were found in the ER protocol. In all tested groups, the achieved SBS value was satisfactory to withstand orthodontic and occlusal forces. There was no significant difference in the ARI score between study groups (p = 0.71). The fracture occurred between the ...
