Dental considerations in patients with heart disease
2011
Summary: Cardiovascular diseases are one of the main causes of death in the developed world, and represent the first cause of mortality in Spain. In addition to their associated morbidity, such disorders are important due to the number of affected individuals and the many patients subjected to treatment because of them. Objective: An update is provided on the oral manifestations seen in patients with arterial hypertension, ischemic heart disease, arrhythmias and heart failure, and on the dental management of such patients. Material and methods: A Medline-PubMed search was conducted of the literature over the last 10 years using the keywords: “cardiopathy”, “dental management”, “endocarditis…
Use of cbct in the endodontic management of a second mandibular premolar with three roots : clinical case
2022
Background Reports and studies on dental anatomy describe variations in the morphology, number and shape of the roots and root canals, with the mandibular premolars being one of the dental groups with special complexity. In the bibliographic review published on the morphology of mandibular second premolars, the presence of three roots being extremely rare, finding differences according to the ethnic group studied. The aim of this case is to describe an unusual case of the anatomy of a mandibular second premolar. Material and Methods A 59-year-old male patient presented with pain in the right mandibular second premolar. After taking the clinical history and the examination, he was diagnosed …
Prevalence of intraoperative and postoperative iatrogenic mandibular fractures after lower third molar extraction: A systematic review
2022
Background The surgical extraction of the lower third molars is one of the most common procedures in oral surgery, and this surgical operation can cause intra- and postoperative complications such as pain, trismus, bleeding, infection, oedema, inferior alveolar nerve injuries, displacement of teeth to neighbouring spaces and mandibular fractures. The aim of this systematic review is to report the prevalence of mandibular fractures that occur intra- and postoperatively in patients who have undergone surgical removal of the lower third molar. Material and Methods An electronic database search for articles published in Cochrane, PubMed (MEDLINE) and Scopus was conducted using the key words “Mo…
Stem cells from human dental pulp and apical papilla: Morphological and synchrotron radiation analysis
2021
Background Dental Mesenchymal stem cells has prompted great for cell-based therapeutics. But no one knows for sure what the true potential of these cells, since most of the studies were done in isolation, using as source, different donors or different cell processing conditions. Material and Methods An enriched population of cells positive for CD146, STRO-1, and CD90 was isolated of third molars teeth indicated for extraction of patient with of 16 years old. Analysis of cell kinetics, and subcellular tests were performed to assess the presence of minor and trace elements by using synchrotron radiation x-ray fluorescence microscopy. Results In the cell kinetics assays, the enriched populatio…
Bond strength of self-adhesive resin cement to dentin using different adhesion protocols
2022
Background The treatment of dentin before the use of self-adhesive cements is still a crucial point to achieve the best bond strength values. The objective of this study was to evaluate the bond strength between dentin and composite resin using different adhesion strategies with self-adhesive resin cement. Material and Methods Forty healthy third human molars were randomly divided into 4 groups (n = 10): CA (control); application of self-adhesive cement (Rely X U200, 3M ESPE), AD + CA: only application of conventional adhesive (Adper Single Bond 2, 3M ESPE) + self-adhesive cement, AC + AD + CA; conditioning with 37% phosphoric acid for 15 seconds + application of conventional adhesive + sel…
Surgical uprighting and repositioning of unerupted molars : features and findings of a retrospective sample
2021
Background Surgical uprighting and repositioning have been proposed to obtain a correct alignment of unerupted permanent molars. A retrospective clinical study was performed to verify the effectiveness of these techniques. Material and Methods In order for a case to be included in the study, adequate clinical documentation was required, including radiographic imaging before and after therapy. The degree of inclination of each treated molar was evaluated on pre-operative panoramic radiographs. Results Fifty-two molars were studied. Molar involvement was more frequent in the mandible (45 cases=86.54%) than in the maxilla (7 cases=13.66%). The mean age of patients treated with completely forme…
Criteria and treatment decisions in the management of deep caries lesions: Is there endodontic overtreatment?
2018
Background The aim of this study was to investigate the diagnostic criteria and treatment decisions in the management of deep caries lesions (DCLs). The null hypothesis tested was that DCLs are managed according to the current scientific evidence. Material and Methods A total of 288 dentists were contacted directly or by mail, and 125 (43%) were included in the study. Dentists were requested to answer a questionnaire about the routine approach to the diagnosis and treatment of DCLs. Logistic regression analyses were carried out to calculate odds ratios (OR). Results Pulp sensitivity tests were used by 65% of dentists when assessing pulpal health in cases of DCLs, particularly those who had …
Relationship between volume of submandibular salivary stones in vivo determined with cone-beam computer tomography and in vitro with micro-computer t…
2021
Background Successful removal of salivary stones depends on exact pretreatment information of the location, the size and shape of the stones. This study aimed to compare the volume of submandibular sialoliths determined by preoperative Cone-Beam Computer Tomography (CBCT) scans with the volume of the removed stones on micro-Computer Tomography (micro-CT) scans. Material and Methods In this study, using twenty-one submandibular sialoliths, the pretreatment volumes in-vivo measured on CBCT were compared to the volumes of removed stones determined by micro-CT scans. The volume measured on micro-CT scans served as the gold standard. Pre-operative CBCT’s and in-vitro micro-CT’s were converted in…
Clinical Behavior of Ceramic, Hybrid and Composite Onlays. A Systematic Review and Meta-Analysis
2020
A systematic review and meta-analysis was performed to analyze the survival of onlay restorations in the posterior region, their clinical behavior according to the material used (ceramic reinforced with lithium disilicate, conventional feldspathic ceramic or reinforced with leucite; hybrid materials and composite), possible complications, and the factors influencing restoration success. The systematic review was based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, without publication date or language restrictions. An electronic search was made in the PubMed, Scopus, Embase, and Cochrane databases. After discarding duplicate publications and stu…
Clinical Behavior of Short Dental Implants: Systematic Review and Meta-Analysis
2020
Short implants are an increasingly common alternative to other surgical techniques in areas where bone availability is reduced. Despite the advantages they offer, a variety of biological repercussions have been described in the literature that can even lead to the loss of these. The aim of this systematic review and meta-analysis was to analyze the impact of the use of short implants on their survival and on peri-implant bone loss, evaluating the influence that length, diameter, and crown-to-implant ratio (C/I) have on these parameters. This systematic review was based on guidelines proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An electronic se…
