ackground and aim: it is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. material and methods: the orthopantomogram (opg) of the first and second molars of a 28-year-old man was made and the teeth were 3d modeled. the stress-deformation analysis ...

multiple adhesive coating is a controversial topic, especially in primary dentition that should be clarified. we evaluated the effect of multiple consecutive adhesive resin coatings on the microshear bond strength (μsbs) of composite resin to primary tooth dentin utilizing a filled (adper single bond plus) and an unfilled (adper single bond) adhesive resin.thirty extracted primary canines were ...

objectives: this study aimed to compare the shear bond strength (sbs) of composite to stainless steel crowns (ssc) using two mechanical surface treatments (msts) and two bonding systems. materials and methods: eighty-four sscs were divided into six groups of 14; group1: no mst+scotchbond universal adhesive (n+u), group 2: surface roughening by a diamond bur+scotchbond universal adhesive (r+u), ...

statement of problem: shear bond strength (sbs) of home and office bleached enamel will be compromised by immediate application of composite restoration. antioxidant agent may overcome this problem. objectives: this in vitro study assessed the effect of green tea extract on shear bond strength of resin composite to in-office and home-bleached enamel. materials and methods: in this experimental ...

o bjectives: bond strength of composite resin to enamel and dentin of primary teeth is lower than that to permanent teeth; therefore, it may compromise the ad- hesive bonding. new methods, such as laser application have been recently intro- duced for tooth preparation. the purpose of this study was to evaluate the effect of tooth preparation with bur and er:yag laser on shear bond strength of c...

Preservation of tooth integrity and strength is important for the long-term survival of endodontically treated teeth. Endodontic treatment and post space preparation requires reduction of the remaining supportive tooth structure. Restorative modalities following root canal therapy must provide sufficient strength for the prosthetic material and tooth structures. This article presents seven key ...

Material and Methods: The Orthopantomogram (OPG) of the first and second molars of a 28-year-old man was made and the teeth were 3D modeled. The stress-deformation analysis ...

BACKGROUND Previous studies have reported a relationship between masseter muscle thickness and tooth loss or limb muscle thickness. However, it is not yet known whether masseter muscle thickness is related to appendicular skeletal muscle mass, and grip strength. The purpose of this study was to determine which of the two variables-tooth loss or appendicular skeletal muscle mass index-is more st...

statement of the problem: porcelain laminate veneer is an esthetic restoration used as an alternative to full veneer crowns and requires minimal tooth preparation. in restoration with porcelain laminate veneers, both the longevity of the laminate and conservation of the sound tooth structure are imperative. purpose: the present study aimed to investigate the shear bond strength of porcelain lam...

OBJECTIVE It has been reported that the non-dominant hand of patients with Charcot-Marie-Tooth disease is stronger than the dominant hand as a result of overwork weakness. The objective of this study was to determine if this hypothesis could be verified in our population. DESIGN Survey. SUBJECTS Twenty-eight patients with Charcot-Marie-Tooth disease type I or II from a rehabilitation depart...
