MODERN VIEW OF THE COMBINED USE OF COMPOSITE MATERIAL AND GLASS IONOMER CEMENT

Наука и инновации в медицине, 2016
The adhesion of resin-modified glass-ionomer (RMGI) to composite resin plays a very important role in the durability of sandwich restorations. Aim - to explore that co-curing RMGIC and composite resin to GIC using self-etch adhesives and bulk-fill ...

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

The Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Clinical performance of indirect hybrid ceramic onlay restorations cemented with injectable resin composite versus dual-cure resin cement: an 18-month randomized clinical trial

BMC Oral Health
Background The cementation of indirect restorations is a critical step influencing their long-term clinical success. While dual-cure resin cements are widely used, injectable resin composites have emerged as promising alternatives, offering improved ...

Comparative Evaluation of Shear Bond Strength of Resin Modified Glass Ionomer Cement and Biodentine as Dentin Substitutes to Bonded Silver Amalgam and Composite Resin [PDF]

Journal of Clinical and Diagnostic Research, 2018
Introduction: The bond strength between the restorative material and the tooth, as well as between the restorative material and the base, is an important factor and can determine the longevity of a dental treatment.

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

The Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Evaluation of stress distribution of a new restorative material and composite resin: a finite-element analysis study

Biotechnology & Biotechnological Equipment, 2017
Glass carbomer cement is a new dental material developed from the traditional glass ionomer cements. It has better mechanical and chemical features when compared to the conventional glass ionomer cements.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Development of phenolic concrete mixes and structural behaviour of phenolic concrete components [PDF]

, 1991
This work relates to the development of a method of preparing a filled phenolic resin, for use particularly, but not exclusively, in building materials. The method includes mixing filler and micro-filler, a catalyst, resin and a hetrocyclic alcohol (i.e.

Five‐year tomographic and clinical evaluation of the socket shield technique: Case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The socket shield technique, one modality of partial extraction therapy, aims to preserve periodontal tissues and maintain the buccal alveolar bone volume following immediate implant placement or in prosthetic pontic sites, by the strategic maintenance of a tooth root fragment.
