Activation of Cannabinoid Receptors Promote Periodontal Cell Adhesion and MigrationAbstract Objective Medical and recreational cannabis use is increasing significantly, but its impacts on oral health remains unclear. The aim of this study is to investigate the effects of tetrahydrocannabinol (THC), the major active component in cannabis, on periodontal fibroblast cell adhesion and migration to explore its role in periodontal regeneration and wound healing. Material and methods The different distribution of cannabinoid- Dimensional changes of buccal bone plate in immediate implants inserted through open flap, open flap and bone grafting, and flapless technique. A CBCT randomized controlled clinical trialAbstract Objectives To assess through Cone‐beam Computed Tomography (CBCT) buccal alveolar bone alterations after immediate implant placement using the following techniques: open flap and grafting (flap‐graft), open flap and no grafting (flap‐nograft), flapless and no grafting (noflap‐nograft). Materials and methods This was a three‐armed parallel group randomized clinical trial with allocation ratio 1:1:1. Patients were eligible in cas
- A complete physical mapping of the VDR gene for dental implant loss: a pilot studyAbstract Objectives The aim of this pilot case‐control study was to investigate the association of clinical variables and genetic polymorphisms in the vitamin D receptor gene (VDR) with dental implant loss. Material and Methods This study was carried out with 244 individuals with mean age 51.90 ± 11.28 (81 cases and 163 controls matched by age, sex and smoking habit). Also, the clusterization phenomenon was investigated stratifying the
- Three-dimensional photographic analysis of the face in European adults from southern Spain with normal occlusion: reference anthropometric measurementsAbstract Background Recent non-invasive 3D photography method has been applied to facial analysis, offering numerous advantages in orthodontic. The purpose of this study was to analyze the faces of a sample of healthy European adults from southern Spain with normal occlusion in order to establish reference facial soft tissue anthropometric parameters in this specific geographic-e
- Can universal adhesive systems bond to zirconia?Abstract Objective To measure the bond strength to zirconia subjected to different surface treatments of universal bonding agents. Materials and methods Eighty blocks of zirconia were obtained by CAD/CAM milling. The blocks were embedded into PVC tubes, polished sequentially with increasing granulation sandpapers and divided into two groups according to surface treatment: polished or grit‐blasted with alumina particles. Each group was t
- The effect of gender and clinical experience on shade perceptionAbstract Objective Shade matching is a critical procedure in prosthetic dentistry. The correct identification of the shade by the doctor as well as the perception of the shade by the dental technician becomes critical due to the high patient expectations. The current study aims to evaluate the effect of gender and clinical experience on shade perception by dental professionals. Materials and Methods A total of 100 dental professionals w
- A one‐year prospective study on alveolar ridge preservation using collagen‐enriched deproteinized bovine bone mineral and saddle connective tissue graft: A cone beam computed tomography analysisAbstract Background Although there is ample research on alveolar ridge preservation (ARP), changes of the soft tissue profile are seldom reported. In addition, the use of a saddle connective tissue graft (S‐CTG) has only been described in one study. Purpose To evaluate changes in bone and external soft tissue profile following ARP of intact and nonintact sockets using collagen‐enriched deproteinized bovine bone mineral (C‐DBBM) and a S‐
- Marginal and internal fit of CAD/CAM frameworks in multiple implant‐supported restorations: Scanning and milling error analysisAbstract Background Despite computer‐aided design and computer‐aided manufacturing (CAD/CAM) technology improving prosthesis fit, errors inherent to digital workflow still exist. Purpose To measure scanning/milling errors, and identify factors influencing marginal (MD) and internal discrepancy (ID). Materials and Methods After scanning, 22 conical abutments in 5 master casts, 6 suprastructures with more than 2 implants (3, 4, and
- Five years follow‐up of mandibular 2‐implant overdentures on locator or ball abutments: Implant results, patient‐related outcome, and prosthetic aftercareAbstract Background It is uncertain, which is the optimal attachment for a mandibular 2‐implant overdenture (2IOD). Purpose To assess 5 years clinical implant outcome, prosthetic maintenance, cost, and PROMs of two cohorts receiving 2IOD on ball or stud abutments in a comparative study. Materials and Methods Ninety edentulous individuals were treated with balls (n = 34) or locator (n = 56). Implant survival, bone‐to‐implant level,
- What is of interest in Endodontology? A bibliometric review of research published in the International Endodontic Journal and the Journal of Endodontics from 1980 to 2019Abstract Aim To report the most common terminology used in titles of scientific papers published in the International Endodontic Journal (IEJ) and Journal of Endodontics (JOE) between 1980‐2019 and to identify the most cited papers in these journals. Methodology The Web of Science database was searched to retrieve all the manuscripts published in the IEJ and JOE between 1980 and 2019. The articles were analyzed using the VOS viewer soft
- Effect of length of apical root resection on the biomechanical response of a maxillary central incisor in various occlusal relationshipsAbstract Aim To investigate the stress distribution and tooth displacement of a maxillary central incisor with various apical root resection lengths and occlusal relationships using finite element analysis. Methodology A maxillary central incisor was scanned by MicroCT. First, the finite element (FE) intact incisor model with dentine, enamel, pulp and root surrounded by alveolar bone and periodontal ligament was designed based on the Mi
- Relationship between unintentional overfilling and the long‐term outcome of primary root canal treatments and non‐surgical retreatment: a retrospective radiographic assessmentAbstract Aim To determine retrospectively the long‐term radiographic outcome of root canal treatments and root canal retreatments with unintentional overfilling. Methodology A total of 220 root canal treatments (143 primary/ 77 retreatments) with postoperative unintentional overfilling and performed by two endodontists during their 45 years of private practice were included in the study. Lateral condensation techniques and nine differen
- Should Healing Abutments and Cover Screws for Dental Implants be Reused? A Systematic ReviewAbstract Purpose : To systematically review the current scientific evidence to assess if healing abutments and cover screws for dental implants can be re‐sterilized effectively for reuse. A secondary purpose was to investigate if there has been any reported adverse biological or mechanical consequences to implants, or harm to patients with the reuse of healing abutments or cover screws. Materials and Methods : An electronic search of th
