The purpose of this study was to assess the influence of two light units, a quartz-tungsten-halogen (QTH) and a light-emitting diode (LED), on the hardness and degree of conversion of an orthodontic composite resin. Sixty specimen disks were prepared from Transbond XT composite resin (3M Unitek) and light cured for 10, 20, and 30 seconds with a QTH (Curing Light XL 3000, 3M Unitek) or a LED (Or...
OBJECTIVE To test the stability of two conventional adhesives when combined with a low-viscosity caries infiltrant used for sealing sound enamel against toothbrush abrasion and acid challenge in vitro. MATERIALS AND METHODS Bovine enamel discs (Ø = 3 mm) randomly assigned to three groups (n = 10/group) were etched with 37% phosphoric acid for 30 s and treated with resins of different monomer ...
هدف درمان اندودنتیک حذف میکروارگانیسم ها و محصولات جانبی آنها از کانال ریشه و همچنین ایجاد سیل مناسب جهت جلوگیری از عفونت مجدد این سیستم می باشد. سیلرهای mta fillapex و iroot sp دو سیلر جدید هستند که بر اساس ادعای سازندگان، ویژگی های بسیار مشابه با mta دارند. هدف از این مطالعه بررسی و مقایسه ی سیل اپیکال کانال های پر شده با سیلرهای iroot sp ، mta fillapex و ah-plus می باشد. 120 دندان پرمولر تک...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
The more clearly the clinician comprehends the processes of clinical perception and of linking the experience with explanation, the more thoughtfully clinical students can be guided to construct an accurate 'clinical memory' of cases, and to construct a sound 'working knowledge' structure from their personal 'examined experience'. The structuring of the steps of clinical learning is intended as...
some studies suggested that glucocorticoid receptors activities can modulate fear and anxiety. according to that, the purpose of this research is to assess the modulatory effect of glucocorticoid receptors on the anxiety assessed in plus maze. in this research mice with medium weight of 20-25 g were used. the male and female animals separately sorted in two groups as control and experiment rand...
The aim of this study was to evaluate the influence of six self-etching primers (SEPs) on the shear/peel bond strength (SPBS) of orthodontic lingual buttons. A total of 150 extracted human premolars were randomly divided into six equal groups. In all groups, the lingual buttons were bonded with BeautyOrtho Bond and the enamel was conditioned with the following-group I (Control): Primers A & B; ...
This clinical trial evaluated, over a 12-month period, the performance of brackets bonded to teeth etched and primed with Transbond Plus Self-Etching Primer (SEP) when compared with a conventional separate two-step etch and primer system. Thirty-nine randomly selected patients requiring fixed appliance therapy were entered into the study. Random allocation of each etching system, along with a '...
o bjectives: the objective of this study was to assess the effect of new bonding techniques on enamel surface. materials and methods: sixty upper central incisors were randomly divided into two equal groups. in the first group, metal brackets were bonded using trans- bondxt and, in the second group, the same brackets were bonded with maxcemelite. the shear bond strength (sbs) of both agents to ...
