Case Report. An 8-year-old girl with amelogenesis imperfecta (AI) reported unsatisfactory aesthetics, difficulty in mastication, and dental hypersensitivity. The intraoral examination observed mixed dentition, malocclusion in anteroposterior relationships, anterior open bite, and dental asymmetry. A hypoplastic form of AI was diagnosed in the permanent dentition. A multidisciplinary planning wa...

Introduction: The growing demand for esthetic dental procedures has resulted in the increased development of new restorative composite resins. The success of composite resin restorations depends on their color stability over time. The present study aimed to evaluate the effects of 0.2% chlorhexidine (CHX) and re-polishing on the color stability of nanofilled composite re...

This clinical report describes a fixed maxillary telescopic dental prosthesis (FTDP) employing milled base metal copings and a metal superstructure veneered with composite resin, for the restoration in a periodontally compromised patient with uncontrolled diabetes. The telescopic prosthesis framework design incorporated occlusal rest seats in key positions along the arch in case of future poste...

objective: secondary caries is a common problem in dental treatments and its occurrence is attributed to several factors. the present study aimed at assessing the prevalence of secondary caries in posterior teeth of patients presenting to the department of operative dentistry, shahid beheshti dental school.   methods: this descriptive study was conducted on 350 patients with 1,339 posterior tee...

30 INTERNATIONAL DENTISTRY – AUSTRALASIAN EDITION VOL. 7, NO. 2 Nanotechnology, on the other hand, has made successful inroads into modern composite technology and continues to be the subject of considerable research work1,12,13. Nanosized inorganic fillers enable the filler content of composite pastes to be maximised while retaining excellent clinical handling properties and at the same time m...

Cytotoxic resin components of common dental bonding agents are known to cause oxidative damage and suppress odontogenic differentiation of dental pulp cells. [1-4] As antioxidants were found to protect cells from cytotoxicity of resin monomers in previous studies,[5-8] we investigated the effects of common antioxidants, such as !-carotene, resveratrol and Vitamin E on anti-differentiation activ...

The population affected by dental erosion due to bulimia is generally very young. This population group has a high aesthetic requirement; the dentition in these patients is severely damaged, especially in the anterior maxillary quadrant. In terms of treatment, it is still controversial whether an adhesive rehabilitation is preferable to a longer-lasting but more aggressive conventional treatmen...

OBJECTIVES The aim of this study was to evaluate the effects of five self-etch dental composite resin cements on the cell viability of bovine dental papilla-derived cells. METHODS The cytotoxicity of composite resin cements (Rely X Unicem Clicker, 3M ESPE; MaxCem; KERR, Panavia F 2.0; Kuraray, BisCem; Bisco and Bistite II DC; Tokuyama) was analyzed in a dentin barrier test device using three-...

OBJECTIVES The purpose of this study was to investigate the effect of differences in the resin-cement elastic modulus on stress-transmission to ceramic or resin-based composite inlay-restored Class II MOD cavities during vertical occlusal loading. METHODS Three finite-element (FE) models of Class II MOD cavity restorations in an upper premolar were produced. Model A represented a glass-cerami...
