This study evaluated the fracture resistance of weakened roots restored with glass fiber posts, composite resin cores and complete metal crowns. Thirty maxillary canines were randomly divided into 3 groups 10 teeth each: without (control); partially (PWR) largely (LWR). The control group was posts a core. Teeth in PWR LWR flared internally to standardized dimensions order simulate root weakness. Thereafter, filled same way as group. specimens exposed 250,000 cycles controlled chewing...

Microleakage can be related to margin misfit. Also, traditional microleakage techniques are time-consuming. This study evaluated the existence of correlation between in vitro fit and a new technique for complete crowns cemented with 3 different luting agents. Thirty human premolars were prepared full-coverage convergence angle 6 degrees, chamfer 1.2 mm circumferentially, occlusal reduction 1.5 mm. Ni-Cr cast either zinc phosphate (ZP) (S.S. White), resin-modified glass-ionomer (RMGI) (Rely X...

Proper selection of the luting agent is fundamental to avoid failure due lack retention in post-retained crowns. The objective this study was investigate tensile bond strength and mode glass fiber posts luted with different cements. Glass were 40 mandibular premolars, divided into 4 groups (n = 10): Group 1 - resin-modified ionomer RelyX Luting; 2 Fuji Plus; 3 resin cement ARC; Enforce. Specimens assessed by testing light microscopy analysis for observation mode. values each group compared...

Noncarious cervical lesions are characterized by loss of tooth structure in the area, compromising its integrity and resulting esthetic problems for patient.The purpose this study was to assess noncarious young patients an attempt establish a possible relationship presence wear facets.First-year dental students Bauru Dental School were studied verify prevalence their facets. After 3 years, examined again incidence new lesions, trying correlation previous existence facets.Of 1,131 teeth...

The wear resistance of denture teeth is important to the longevity removable prostheses edentulous patients. ability maintain a stable occlusal relationship over time may be influenced by this property. purpose in vitro study was evaluate polymethyl methacrylate (PMMA) based on their chemical composition when opposed ceramic antagonist. maxillary canines (n=10) 3 PMMA (Trubyte Biotone, cross-linked PMMA; Trilux, highly IPN (interpenetrating polymer network)-PMMA; and Vivodent, PMMA) were...

Objective Since the transmittance of ceramics can influence degree conversion (DC) resin cements, composition and shade should be considered in selection cement. This vitro study aimed to evaluate effect different composition, opacities shades on two dual-cured cements. Methodology Sixty discs were prepared from low translucency (LT) medium opacity (MO) lithium disilicate ceramic, zirconia ceramic (Z). Each group was subdivided into 5 subgroups (n=4) A2, A3.5, B2, C2 D3. The measurement...

The mechanical removal of dentinal caries traditionally involves the use tactile sensation and/or caries-indicating dyes. This study tested hypothesis that self-limiting polymer burs are as effective conventional carbide in creating substrates for dentin bonding. Carious from extracted human molars was removed with or burs, dental explorer hardness end-point removal. Dentin were bonded etch-and-rinse self-etch adhesives and prepared microtensile bond testing transmission electron microscopy....

In dentistry, investigations in the field of periodontics individuals with cleft lip and palate are scarce, few studies on prevalence, incidence, extension, severity periodontal alterations their treatment adults.This study analyzed recessions relationship some etiologic factors 200 aged 13 to 56 years. Examination comprised measurements gingival recession, amount keratinized mucosa, frenum insertions, tooth positioning dental arch.Analysis results revealed that prevalence recession was...

ABSTRACT Purpose: Chipping within veneering porcelain has resulted in high clinical failure rates for implant‐supported zirconia (yttria‐tetragonal polycrystals [Y‐TZP]) bridges. This study evaluated the reliability and modes of mouth‐motion step‐stress fatigued Y‐TZP versus palladium‐silver alloy (PdAg) three‐unit Materials Methods: Implant‐abutment replicas were embedded polymethylmethacrylate resin. PdAg frameworks, similar design ( n = 21 each), fabricated, veneered, cemented 3 Hertzian...

This study aimed at evaluating the effectiveness of partial use anterior repositioning appliances in management TMJ pain and dysfunction when compared to stabilization splints a control group one-year follow-up. Sample was initially constituted by 60 patients, randomly divided into three groups: I- splints, II- III- no treatment. The whole sample evaluated means muscle palpation, mandibular AROM, analysis occlusal contacts, joint sounds inspection Visual Analogue Scale (VAS) for one year; 52...

Hypodontia is the congenital absence of one or more teeth and may affect permanent teeth. Several options are indicated to treat hypodontia, including maintenance primary space redistribution for restorative treatment with partial adhesive bridges, tooth transplantation, implants. However, a multidisciplinary approach most important requirement ideal hypodontia. This paper describes plan congenitally missing mandibular second premolars involving orthodontics, implantology prosthodontic specialties.

To evaluate biologic and prosthetic outcomes of implant-supported mandibular full-arch fixed prostheses treated with the All-on-4 treatment concept after 7 years.Patients were selected to receive immediate supported by four implants up 72 hours surgery. The following aspects evaluated: Plaque Index (PI) Bleeding (BI), implant stability resonance frequency, marginal bone loss (MBL) measured aid periapical radiographs. complications evaluated related screw loosening, framework or acrylic teeth...

The aim of this study was to compare the resistance endodontically treated teeth with intraradicular retainer different amounts remaining coronal structure. Fifty freshly extracted maxillary canines were and randomly assigned five groups (n=10), as follows: group 1 (control) = custom cast post core; 2 without structure; 3, 4 5 mm, mm 3 structure, respectively. All specimens in restored prefabricated resin core. embedded acrylic fracture strength measured on a universal testing machine at 45...

summary The aim of this study was to evaluate the fracture resistance endodontically maxillary premolars restored with mesio‐occlusal‐distal (MOD) inlays made ceramic (IPS‐Empress 2) and ceromer (Targis) luted three different dual‐cured resin cements (Enforce, Variolink II, Panavia F). Sixty were randomly distributed into six groups, according their mesio‐distal facio‐lingual dimensions. teeth treated MOD cavities prepared. After restorations cemented, samples thermocycled submitted an axial...

The aim of this study was to evaluate the influence remaining coronal tooth structure on endodontically treated teeth restored with prefabricated posts and two different composites for core build-up: dual-cured resin (Enforce Core) light-cured (Z-250).Fourty freshly extracted canines were divided into four groups: Group I - 3mm structure, Enforce Core; II Z-250; III no Enforce; IV Z-250. After restoration, embedded in acrylic fracture resistance measured a universal testing machine at 45...
