Various strategies for intraoral scanners (IOSs) can be used to scan the oral cavity. However, research on range that clinically is lacking.The purpose of this in vitro study was compare 3-dimensional (3D) distortion complete arch scans as part strategy and analyze recommended range.A computer-aided design (CAD) reference model obtained with an industrial scanner. A CAD test by using 6 IOSs (TRIOS2, TRIOS3, CS3500, CS3600, i500, Primescan) apply 2 dental laboratory (DOF E1) (N=15). All teeth...
The purpose of this clinical study was to evaluate the extent intraoral occlusal adjustment required for zirconia crowns designed with a dynamic jaw motion tracking method compared conventional approach. Fifteen patients needing crown restorations in anterior or posterior regions participated study. Following tooth preparation, records were gathered using device. These imported into computer-aided design software and aligned scanned upper lower data each crown's surface. Two fabricated...
Diastema closure using direct bonding restorations combined with orthodontic treatment: a case reportClosure of interdental spaces proximal build-ups resin composite is considered to be practical and conservative.However, comprehensive approach combining two or more treatment modalities may needed improve esthetics.This report describes the management patient multiple diastemas, peg-shaped lateral incisor midline deviation in maxillary anterior area.Direct along movement teeth allows space...
In mouse tooth development, the roots of first lower molar develop after crown formation to form 2 cylindrical by post-natal day 5. This study compared morphogenesis and cellular events mesial-root-forming (MRF) bifurcation-forming (BF) regions, located in mesial center molar, better define developmental mechanisms involved multi-rooted formation. We found that mesenchyme MRF showed relatively higher proliferation than bifurcation region. suggested spatially regulated mesenchymal is required...
Hydroxyapatite treated with recombinant human bone morphogenetic protein-2/Hydroxyapatite (rhBMP-2/HA) or bovine was applied on extraction sockets for alveolar ridge preservation, and the results were compared respect to clinical histological formation.This a prospective, randomized controlled trial performed 20 implant placement sites (10 in experimental 10 control group). rhBMP-2/HA group those of group. The at corresponding biopsied 3 months later, clinical, histological,...
This study aimed to evaluate the needs of dentists, dental technicians, hygienists, and dental-related workers in terms computer-aided design (CAD) software artificial intelligence (AI). Based on a factor analysis, 57 survey items were assigned six categories: (a) considerations when purchasing CAD software; (b) prosthesis process; (c) function; (d) use AI crown denture design; (e) impact AI; (f) improvements features. Overall, 93 participants included study, reliability resultant data was...
This study evaluated the anatomical profile of mesial root canals Burmese mandibular first molar with Vertucci's type IV canal configuration (VT4) using microcomputed tomography analysis. Seventy-five roots extracted molars were scanned and evaluated. Fourteen middle (MMCs) observed in specimens; each specimen had an average 1.63 lateral 3.77 apical foramina. The arising from mesiobuccal canal, mesiolingual MMC, isthmus terminated at distance 0.92, 0.73, 2.11, 1.89 mm, respectively, apex....
The purpose of this study was to evaluate muscle activation and fatigue in the operator during tooth preparation intraoral scanning by simulating these tasks two types dental unit chair systems (UCS). Six participants were recruited, above simulated. Electrodes placed on skin over five muscles (arm, neck, shoulder muscles), maximal voluntary contraction (MVC) measured. Electromyography (EMG) assessed simulation, EMG values normalized using MVC. root mean square (RMS) (%MVC) (%) calculated....
Background and Objectives: The purpose of this study is to observe the usefulness autogenous tooth transplantation by examining cumulative survival rate according period auto-transplanted teeth as pre-implant treatment. Materials Methods: This was conducted on 111 patients who visited Kyungpook National University Dental Hospital underwent between November 2008 January 2021 (about 13 years). causes extraction recipient (caries, periapical lesion, crack, crown fracture, periodontitis)...
(1) Background: The purpose of this study was to evaluate how a zirconia implant surface treated with laser technology affects the degree biofilm formation. (2) Methods: Experimental titanium (Ti) disks were produced that sandblasted large grit and acid-etched (T), they compared (ZrO2) discs machined (M) topography; hydrophilic topography femtosecond (HF); hydrophobic nanosecond (HN) (N = 12 per group). An in vitro three-species sample (Aggregatibacter actinomycetemcomitans (Aa),...
Diagnostic challenges of nonodontogenic toothacheThe objective this article was to present two conditions that may mimic odontogenic toothache: trigeminal neuralgia and burning mouth syndrome.Two cases are presented in which one is related the upper left second premolar other first molar.Both showed pain when chewing.These highlight complexities involved diagnosing toothache.This demonstrates importance having a thorough knowledge both toothache, as well need for careful evaluation nature...
The purpose of this study was to evaluate the proximity mandibular molar apex buccal bone surface in order provide anatomic information for apical surgery.Cone-beam computed tomography (CBCT) images 127 first molars and 153 second were analyzed from 160 patients' records. distance measured root 3.0 mm on cross-sectional view CBCT.The 3 located significantly deeper relative compared with (p < 0.01). For molars, shorter patients over 70 years age 0.05). Furthermore, when missing nonmissing...

Screw-in effect is one of the unintended phenomena that occurs during root canal preparation with nickel-titanium rotary files. The aim this study was to compare screw-in among various file systems. Six different instruments (ISO 20/.06 taper) were used: (SybronEndo, Glendora, CA, USA), (VDW GmbH, Munchen, Germany), NRT safe-tip and active tip (Mani Inc., Shioya-gun, Japan), ProFile (Dentsply-Maillefer, Ballaigues, Switzerland) ProTaper Switzerland). For ProTaper, S2 selected because it has...
