Dental bonding materials are widely used in dentistry and there several available kinds. However, recent years, has been no further research into dental materials, with most dentists focusing on implants orthodontics. In this paper, we systematically review the technology of tooth years summarize existing literature for potential innovation direction future research. First, theoretical assembly...

In complex cases of enamel fluorosis or enamel dys-mineralization, combined bleaching and micro-abrasion therapies may be advocated. The aim of the present study was to investigate the effect of combined in-office bleaching and micro-abrasion on the bond strength of two dental adhesives bonded to surface enamel. The interfacial micro-morphology of the involved surfaces was also studied by using...

Written and clinical tests compared the change in clinical knowledge and practical clinical skill of first-year dental students watching a clinical video recording of the three-step etch-and-rinse resin bonding system to those using an interactive dental video game teaching the same procedure. The research design was a randomized controlled trial with eighty first-year dental students enrolled ...

OBJECTIVES To examine the effects of dental fluorosis and total and self-etch bonding systems on microleakage of Class-V composite restorations in permanent molar teeth. METHODS Teeth were classified as three main groups according to Thylstrup-Fejerskov Index (TFI) as TFI=0, TFI=1-3 and TFI=4. Total and self-etching/bonding procedures were determined for each main group. Total-etching procedu...

The purpose of this article is to explore differences in the socioeconomic, demographic characteristics of older adults in the United States with respect to their use of different types of dental care services. The 2008 Health and Retirement Study (HRS) collected information about patterns of dental care use and oral health from individuals aged 55 years and older in the United States. We analy...

In vitro tensile bond strengths were determined for three adhesive cements and two resin-bonded bridge cements to two alloys, each prepared by two methods: sandblasted Ni-Cr-Be alloy (I), electro-etched Ni-Cr-Be alloy (II), sandblasted Type IV gold alloy (III), and tin-plated Type IV gold alloy (IV). Storage conditions of 24 hours at 37 degrees C and 30 days at 70 degrees C were evaluated. The ...

objective: successful bonding of a dental implant to bone, which was referred to as osseointegration by branemark has been well documented. however, long-term prognosis of an implant depends on adequate maintenance and long-term care. an effective maintenance program is required to preserve the health of peri-implant tissues. several techniques have been suggested for this purpose but it is not...

Current dental adhesive technology involves either an etch-and-rinse or self-etching approach.8 Evidence of clinical durability exists for both approaches, albeit depending on the specific brand.4,5 Today, enamel still requires phosphoric-acid etching and thus an etch-andrinse approach to obtain a durable bond. The adhesiveenamel bond seals the cavity and even protects the more vulnerable bond ...

background: the aim of this study was to compare the effects of conventional acid etching and laser etching on the nano-mechanical properties of the dental enamel using nano-indentation test. materials and methods: in this experimental in vitro study, buccal surfaces of 10 premolars were divided into three regions. one of the regions was etched with 37% phosphoric acid and another etched with e...
