Aim: To compare the amount of remaining cement excess after cementation of implant-supported zirconia crowns with zinc phosphate or calcium aluminate glass ionomer cement.
Materials And Methods: Twenty zirconia crowns were cemented on dental implant abutments using a calcium aluminate glass ionomer cement (n = 10) and zinc phosphate cement (n = 10). After removal of cement excess, remaining cement excess were measured with pixel area calculation method and by weighing. Differences in amount of remaining cement excess were analyzed using Independent Samples t-Test. Level of significance was set at p = 0.05.
Results: Zinc phosphate cement had a significantly greater amount of remaining cement excess than calcium aluminate glass ionomer cement in terms of total number of pixels (p = 0.002) and amount in grams (p = 0.005).
Conclusion: The study suggests that the amount of remaining cement excess can be affected by the type of cement. Calcium aluminate glass ionomer cement may be a more suitable choice for cement-retained dental implant restorations, and possibly reduce the risk of complications related to cement excess such as peri-implant disease. Further studies are needed to verify the results from the present study.

Bonding performance of universal adhesive systems with dual-polymerising resin cements to various dental substrates: in vitro study.

Background: Resin cements often require substrate-specific pretreatment. Recently, universal adhesive systems have been introduced, simplifying procedures by eliminating the need for multiple adhesives and offering options that do not require light curing. This study investigated the bonding performance of universal adhesive systems combined with dual-polymerising resin cements on enamel, dentin, zirconia, lithium disilicate ceramics (LDS), and resin blocks.

Background: Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a painful disorder primarily affecting the incisor teeth of horses over 15 years of age. Clinical signs of the disease include prehension problems, halitosis and in severe cases weight loss. The disease predominately affects the reserve crown and presents as a loss of dental tissue and excessive build-up of cementum.

Background: Revision total elbow arthroplasty (rTEA) remains a technically challenging procedure with potential for substantial morbidity. Cases involving excessively long cement mantles, removal of well-fixed implants or infected revisions requiring complete cement removal introduce additional technical challenges. Our purpose was to describe the outcomes, results, and complications associated with the use of cortical windows in rTEA.

The aim of this study was to assess the effect of a chlorhexidine digluconate solution (CHX) applied as an antiproteolytic agent for controlling erosive tooth wear or as part of the adhesive treatment on long-term bond strength to eroded dentin. Dentin specimens were abraded with a 600-grit silicon carbide (SiC) paper for 1 min (sound dentin - S), subsequently treated with 2% CHX for 1 min (with excess removed, followed by a 6-hour rest), and eroded by exposure to Coca-Cola for 5 min, three times a day, for 5 days (CHX-treated and eroded dentin - CHXE), or only eroded (eroded dentin - E). The specimens were acid-etched (15 s), rinsed (30 s), dried (15 s), and rehydrated with 1.

Background: Crown cementation is a common technique for implant-supported prosthodontics. However, for possible slipping of the cement below the mucosal margin, its thorough removal poses some issues. The objective of this study was to evaluate the presence of submucosal cement residues in patients with peri-implant disease by endoscopic visualization and to investigate the potential correlation between the pathological scenario and the spatial position of cement residues.
