The early detection of initial dental caries enables preventive treatment, and bitewing radiography is a good diagnostic tool for posterior caries. In medical imaging, the utilization deep learning with convolutional neural networks (CNNs) to process various types images has been actively researched, promising performance. this study, we developed CNN model using U-shaped (U-Net) on radiographs investigated whether can improve clinicians' research complied relevant ethical regulations....
Summary The purpose of this study was to evaluate the effect various surface treatments on shear bond strength Y‐TZP (Yttria‐Tetragonal Zirconia Polycrystal) ceramics with zirconia primer and two different resin cements both containing 10‐methacryloyloxydecyl dihydrogen phosphate (MDP). blocks (LAVA, 3M ESPE, St. Paul, MN) were polished assigned five groups according treatment: (1) no further treatment (control); (2) airborne abrasion Al 2 O 3 particles; (3) Z‐PRIME Plus (Bisco, Schaumburg,...
Abstract The aim of this two-center randomized controlled trial was to assess the outcomes and relative factors associated with pulpotomies performed using a premixed injectable calcium silicate cement, as compared mineral trioxide aggregate in mature permanent premolar molar teeth reversible pulpitis. Included were randomly divided into two groups according pulpotomy material (ProRoot MTA [PMTA] group, Endocem Premixed [EPM] group). After pulp exposure, superficial either removed depth 2 mm...
ABSTRACT Objective Although several studies have compared fragment attachment with resin build‐ups in anterior crown fractures, none specifically investigated the outcome of reattached fragments. This retrospective study aimed to evaluate long‐term outcomes reattachment fractures and determine prognostic affecting their success. Materials Methods We retrospectively analyzed clinical records patients who underwent for teeth (maxillary mandibular central lateral incisors) between 2008 2023....
The purpose of this study was to investigate the influence insufficient light exposure on polymerization conventional and self-adhesive dual-cure resin cements under ceramic restorations.Two (Rely-X ARC, Duolink) two U200, Maxcem Elite) were polymerized different curing modes (dual-cure or self-cure), times (20 120 seconds), thickness a overlay (2 4 mm). Polymerization kinetics measured by Fourier transform infrared spectroscopy for initial 10 minutes after 24 hours. Data analyzed using...
The purpose of this study was to examine and compare color translucency stability three-dimensional (3D) printable dental materials for crown bridge restorations. Five different were investigated, twelve disc-shaped specimens two thicknesses (1 2 mm) prepared using a digital light processing 3D printer. Color measurements made according the CIELAB scale (L*, a*, b*) spectrophotometer 1 h, day, week, one month, six months after post-curing materials, parameter (TP) calculated. L*, b*, TP...
Objectives The aim of this study was to determine the clinical efficacy newly developed Ortho MTA and Retro , compared conventionally used ProRoot for pulpotomy in primary teeth. Material Methods In randomized trial, 151 molars from 102 children, who met inclusion criteria were 3–10 years old, enrolled. Ultimately, 143 teeth divided a randomized, single‐blind manner into three groups according planned treatment: ( n = 49 teeth), 47 teeth) or teeth). Clinical radiographic follow‐up...
This study investigated the influence of preparation design on marginal and internal gap ceramic thickness partial crowns (PCCs) fabricated with CEREC 3 system.Sixteen extracted human mandibular molars were prepared according to two different designs (n = 8): a retentive traditional cusp capping (Group I) non-retentive horizontal reduction cusps II). PCCs from IPS Empress CAD system. The parameters for luting space minimum occlusal set 30 μm 1.5 mm, respectively. cemented their corresponding...
The purpose of this study was to measure the microshear bond strength (μSBS) four different self-adhesive resin cements with/without 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-containing primer zirconium ceramics and evaluate effect zirconia primers on these (SARCs).Zirconia blocks (20 × 20 8 mm3) were prepared divided into eight groups (n=20). They sandblasted (50 μm Al2O3) treated as follows: no or (Z-Primer Plus). Four (MDP-containing: Permacem 2.0 [PC], Clearfil SA luting [CS];...
Endodontic microsurgery is defined as the treatment performed on root apices of an infected tooth, which was unresolved with conventional canal therapy.Recently, advanced technology in 3-dimensional model reconstruction based computed tomography such cone beam has opened a new avenue application personalized, accurate diagnosis and been increasingly used field dentistry.Nevertheless, direct intra-oral localization apex information extremely difficult significant amount bone removal...
Dental clinics are exposed to various uncomfortable noises. The aim of this study was quantify the effectiveness active noise control devices in dental treatment conditions. Two types commercial headsets (Airpods Pro, QC30) and two (Alltalk, Quieton Dental) were used for experiment. Three sounds (high-speed handpiece, low-speed suction system) measured at three different distances from teeth model, typodont. 10, 40, 70 cm reflected positions patient, assistant, practitioner’s ears,...
This study evaluated the fracture resistance, biaxial flexural strength (BFS), and dynamic mechanical analysis (DMA) of three-dimensional (3D) printing resins for esthetic restoration primary molars. Two 3D resins, Graphy (GP) NextDent (NXT), a prefabricated zirconia crown, NuSmile (NS), were tested. GP NXT samples printed using workflow recommended by each manufacturer. Data collected statistically analyzed. As result resistance test 0.7-mm-thick resin crowns with thickness similar to that...
