Abstract Objective: To assess microleakage of a tooth-adhesive-bracket complex when metal or ceramic brackets were bonded with conventional and an antibacterial self-etching adhesive. Materials Methods: Forty freshly extracted human premolars randomly assigned to four equal groups received the following treatments: group 1 = Transbond XT + bracket, 2 3 Clearfil Protect Bond 4 bracket. After photopolymerization, teeth kept in distilled water for month thereafter subjected thermal cycling (500...

Abstract Aim To report the frequency and distribution of root‐filled teeth as well prevalence apical periodontitis in an adult population Turkey. Summary Digital panoramic radiographs 1000 patients who were examined at Baskent University Faculty Dentistry between December 2004 May 2005 evaluated. Patients ageing <15 years those with less than nine remaining excluded. The coronal periapical status all exception third molars was according to criteria proposed by De Moor et al. (2000) ....

Abstract Aim To compare the area of sealer surrounding root fillings completed by two coated carrier systems (Thermafil Obturator and System GT Obturator) cold lateral compaction technique, following canal preparation with different NiTi rotary (Profile ISO GT). Methodology Sixty extracted human mandibular premolars were instrumented ProFile 0.06 taper instruments ( n = 30 each). The teeth divided into four subgroups 15) for filling as following: group 1: + Thermafil Obturator, 2: Cold...

Clinical Relevance Based on the in vitro results of this study, restoration a tooth with an overflared root canal, using individually shaped polyethylene reinforced dowels, may help to reduce microleakage.

The aim of this study was to compare the vertical fracture resistance roots obturated with different root canal filling materials and sealers. Crowns 55 extracted mandibular premolar teeth were removed provide lengths 13 mm. Five saved as negative control group (canals unprepared unfilled). Fifty canals instrumented then five positive prepared but remaining 45 randomly divided into three experimental groups (n = 15 root/group) following procedures: in 1, glass ionomer-based sealer cone...

To evaluate the effect of intracoronal bleaching agents on sealing properties different intraorifice barriers and root filling materials.The canals extracted human premolars (n=180) were prepared by using System GT rotary files filled with either gutta-percha+AH Plus or Resilon+Epiphany sealer. In both groups, coronal 3mm was removed replaced one following materials applied as (n=30/group): 1. ProProot-MTA; 2. Conventional Glass ionomer cement; 3. Hybrid resin composite. each subgroup,...

Abstract The aims of this study were to develop a new classification for pre‐eruptive intracoronal resorption(PIR) with different resorption areas and sizes compare the scores among observers from specialities professional experience. PIR was evaluated according by two dentomaxillofacial radiologists endodontists. Information regarding patient's age, gender, systemic diseases, number PIR, affected tooth area size recorded. system showed that six seven defects most detected. Regarding jaw...

This study evaluated the effects of different final irrigation regimens on dentin tubule penetration three root canal sealers using confocal laser scanning microscopy (CLSM). A total 160 single-rooted extracted mandibular premolar teeth were divided into five groups ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>n</mi> <mo>=</mo> <mn>32</mn> </math> each) according to solution used in rinse protocol, as follows: 17% ethylenediaminetetraacetic acid (EDTA) (group 1), EDTA and...

ABSTRACT Objective The aim of this in vitro study was to investigate whether mixing with calcium hydroxide [Ca(OH) 2 ] affects the antimicrobial action Octenidine hydrochloride (Octenisept), MTAD and chlorhexidine against Enterococcus faecalis Candida albicans . Materials methods Freshly grown cultures faecalis, a mixture both strains were incubated agar plates containing brain-heart infusion broth (BHIB). Zones inhibition measured at 24 48 hours. Statistical analysis performed using...

The aim of this study was to evaluate the effects sodium ascorbate on bond strength different adhesive systems NaOCl-treated dentin. Eighty extracted molar teeth were used in study. buccal enamel surfaces removed obtain a flat dentin surface. mounted self-curing resin and irrigated with NaOCl for 10 min. Half specimens treated randomly assigned four subgroups according (Clearfil SE Bond, Clearfil Tri-S Adper Prompt-L-Pop, Single Bond 2). strengths determined Universal Testing Machine, at...

This study evaluated the antimicrobial efficacy of Er:YAG laser activation with photon-initiated photoacoustic streaming (PIPS), Nd:YAG disinfection, and conventional irrigation on Enterococcus faecalis biofilms using scanning electron microscopy (SEM). Biofilms were grown 110 root halves divided into following: Groups 1 2 (saline 1% NaOCl apical position PIPS, resp.), 3 4 coronal 5 6 (Nd:YAG after saline irrigation, resp.) 7, 8, 9 (conventional NaOCl, 6% saline, resp.). SEM images apical,...

Abstract – Traumatic dental injuries often occur to the teeth and their supporting tissues they are main reasons for emergency visit a clinic. Management of fracture depends on its position extent root involvement. Horizontal fractures not seen frequently treatment consists reduction long‐term rigid fixation coronal segment. The present case demonstrates successful management two horizontally fractured maxillary central incisors with follow‐up period 9 months.

This study aimed to compare the three index systems designed for cone-beam computed tomography (CBCT) in terms of intra- and inter-observer agreement. 117 root-filled teeth with or without periapical radiolucency from 77 already existing CBCT images were chosen randomly. Two observers evaluated status selected graded scores twice using (CBCTPAI), endodontic (ERI) complex (COPI) part scale (PESS), respectively. The researchers' self-agreement kappa values ranged substantial almost perfect. A...
