STATEMENT OF PROBLEM The fracture of implant-supported restorations, especially of the veneering layer, is a common problem in dentistry. Monolithic ceramic or resin restorations might help solve this problem. PURPOSE The purpose of this in vitro study was to obtain additional insight into the risk of fracture of implant-supported restorations. MATERIAL AND METHODS Identical crowns (n=10) o...

PURPOSE To evaluate the marginal fit of CAD/CAM copings milled from hybrid ceramic (Vita Enamic) blocks and lithium disilicate (IPS e.max CAD) blocks, and to evaluate the effect of crystallization firing on the marginal fit of lithium disilicate copings. MATERIALS AND METHODS A standardized metal die with a 1-mm-wide shoulder finish line was imaged using the CEREC AC Bluecam. The coping was d...

background: related multidrug resistance (mdr) to efflux pumps is a significant problem in treating infections caused by pseudomonas aeruginosa (p. aeruginosa). plant compounds have been identified as pump inhibitors (epis). in the current study, the potential effect of berberine and palmatine as epis were investigated on efflux pump inhibition through focusing on different gene patterns in p. ae...

background: the pathogenesis of nontypeable haemophilus influenzae (nthi) begins with adhesion to the rhinopharyngeal mucosa. almost 38-80% of nthi clinical isolates produce proteins that belong to the high molecular weight (hmw) family of adhesins, which are believed to facilitate colonization. methods: in the present study, the prevalence of hmwa, which encodes the hmw adhesin, was determined...

The objective of this study was to evaluate the effect of passive or active phosphoric acid (PA) application after hydrofluoric acid (HA) treatment on the microshear bond strength of lithium disilicate. Thirty ceramic discs were made with IPS Emax 2 (10 mm thick and 10 mm diameter). The specimens were divided into 3 groups, A: 9.6% HA application; AF: 9.6% HA application + cleaning with 37% PA ...

&lt;b&gt;Aim: &lt;/b&gt;This study aimed to estimate the association of coronary artery disease complexity with non-HDL-C levels in premature CAD.&lt;br /&gt; &lt;b&gt;Background: &lt;/b&gt;Primary prevention has utmost importance terms minimizing number patients who had (CAD). Non-high density lipoprotein cholesterol (non-HDL-C) contains potentially atherogenic fractions.&lt;br &lt;b&gt;Materi...

background: the presence of rennin-angiotensin components in mammalian ovaries and their involvement in ovarian physiology have been established. in the present study, effects of angiotensin ii (ang ii) on sodium-potassium adenosine triphosphatase (na+/k+/atpase) expression and development of sheep embryos was evaluated. methods: the abattoir-derived cumulus oocyte complexes (coc) were randomly...
