Effect of incision design on interproximal bone loss of teeth adjacent to single implants. A randomized controlled clinical trial comparing intrasulc…
2018
PURPOSE To evaluate the effect of incision design in implant surgery on interproximal bone loss of posterior teeth adjacent to interdental single implants, comparing intrasulcular and paramarginal incision. A further aim was to assess the influence of the incision technique on peri-implant bone remodeling. MATERIALS AND METHODS A controlled randomized clinical trial was carried out in a University Clinic. All the patients received an interdental posterior single implant. The incision type was randomly divided into two groups: (a) intrasulcular or (b) paramarginal. Standardized periapical digital radiographs were made with the parallel technique and a silicone index individualized in each pa…
Gingival recession and associated factors in a homogeneous Mexican adult male population : a cross-sectional study
2011
Background: Diverse variables are implicated in the pathogenesis of gingival recession; more detailed knowledge about the relationship between the clinical presentation of gingival recession and assorted risk indicators may lead to improved patient monitoring, early intervention, and subsequent prevention. The objective was to evaluate clinically gingival recession in a homogeneous Mexican adult male population and to determine the strength of association with related factors. Method: A cross-sectional study was carried out in a largely homogeneous group in terms of ethnic background, socioeconomic status, gender, occupation, and medical/dental insurance, in Campeche, Mexico. Periodontal ex…
A double blind controlled trial comparing three treatment modalities for dentin hypersensitivity
2011
Aim: This randomized, double blind, split mouth study was aimed to compare three dentin desensitizing treatment modalities. Methods: Two hundred sixty teeth of 25 patients; each having at least 2 hypersensitive teeth in each quadrant, were included. Teeth were randomized to 4 groups: Group A treated with 2% NaF solution, Group B received GLUMA®; an aqueous solution of Hydroxy-Ethyl-Methacrylate and Glutarldehyde, (HEMA-G), Group C received iontophoresis with distilled water (placebo) and Group D was treated with NaF-iontophoresis. Pain response was evaluated on a visual analogue scale (VAS), by using tactile, air blast and cold-water stimuli at 0-day, 15-day, 1-month and 3-months interval. …
Supportive periodontal therapy and periodontal biotype as prognostic factors in implants placed in patients with a history of periodontitis
2013
Objectives: To evaluate bone loss around implants placed in patients with a history of treated chronic periodontitis and who did or did not attend supportive periodontal therapy, after one year in function. Furthermore, the influence of periodontal biotype and level of plaque was also evaluated. Material and Methods: Forty-nine patients participated voluntarily in the study. All subjects had a history of chronic periodontitis, which had been previously treated. After the active treatment, 27 patients attended supportive periodontal therapy (SPT) and the rest did not (No SPT). The O’Leary plaque index and periodontal biotype were recorded for each subject and 246 Astra Tech® OsseospeedTM imp…
Prevalence of fimA genotypes of Porphyromonas gingivalis and other periodontal bacteria in a Spanish population with chronic periodontitis
2012
Objectives: The aim of this study was to determine the prevalence of the different fimA genotypes of Porphyromonas gingivalis in adult Spanish patients with chronic periodontitis, patients with gingivitis and periodontally healthy subjects, and the relationship between these genotypes and other periodontopathogenic bacteria. Study design: Samples of subgingival plaque were taken from 86 patients (33 with chronic periodontitis, 16 with gingivitis, and 37 periodontally healthy) in the course of a full periodontal examination. PCR was employed to determine the presence of the 6 fimA genotypes of Porphyromonas gingivalis (I-V and Ib) and of Aggregatibacter actinomycetemcomitans, Tannerella fors…
Morphology and dimensions of the dentogingival unit in the altered passive eruption.
2011
Objetives: This study define altered passive eruption (APE) and evaluate the morphology of the dentogingival unit. Material and Methods: 123 individuals subjected to clinical examination and parallel profile radiography of the upper central incisor. An evaluation was made of the correlation between the clinical diagnosis of APE and the degree of gingival overlap; by using a 19% overlap to define APE (Kappa concordance index = 0.7). The Mann-Whitney / Wilcoxon test was used to identify the variables influencing APE. Results: Statistically significant differences were observed between the teeth with and without APE: gingival width (p = 0.0073), clinical crown length (p = 0.0000), smiling expo…
Diagonal ear lobe crease and atherosclerosis : a review of the medical literature and dental implications
2011
In Spain a significant number of individuals die from atherosclerotic disease of the coronary and carotid arteries without having classic risk factors and prodromal symptoms. The diagonal ear lobe crease (DELC) has been characterized in the medical literature as a surrogate marker which can identify high risk patients having occult atherosclerosis. This topic however has not been examined in either the medical or dental literature emanating from Spain. The majority of clinical, angiography and postmortem reports support the premise that DELC is a valuable extravascular physical sign able to distinguish some patients at risk of succumbing to atherosclerosis of the coronary arteries. A minori…
A systematic review and meta-analysis on the effectiveness of xenograft to prevent periodontal defects after mandibular third molar extraction.
2021
Background To evaluate the use of guided bone regeneration with xenograft to prevent periodontal defect in the distal aspect of the second molar after the surgical removal of the mandibular third molar. Material and Methods Three electronic databases (Pubmed, Cochrane Library and Scopus) were searched in April 2020. Randomized clinical trials in non-smokers and healthy patients, with at least six months follow-up, comparing periodontal probing depth, clinical attachment level, alveolar bone level and adverse events were selected by two independent investigators. The risk of bias assessment of the selected studies was evaluated by means of the Cochrane Collaboration’s Tool. Finally, a meta-a…
On the search of the ideal barrier membrane for guided bone regeneration
2018
Background GBRs are essential procedures in implant dentistry and periodontology where barrier membranes play an important role by isolating soft tissue and allowing bone to grow. Not all membranes function the same way, as they differ from their origin and structure, it is important to understand how membranes behave and differ one from others in order to achieve a predictable treatment. Material and methods A systematic search on Medline by two independent reviewers was performed for articles published until July 2017 reporting the characteristics or properties of barrier membranes. The question that preceded the search was designed according to PICO rules. Results A total of 124 articles…
Is measurement of the gingival biotype reliable? Agreement among different assessment methods.
2019
Background To determine agreement among the most commonly used methods for assessing the gingival biotype. Material and Methods An electronic survey was sent to a sample of dentists practicing in Spain. The questionnaire was based on the evaluation of 5 cases involving different gingival biotype assessment methods. Dentists were required to classify the cases as having a “thin”, “thick” or “not able to classify” biotype. Each case was assessed using a frontal intraoral photo of the anterior teeth; an enlarged photo of the buccal aspect of the tooth with a periodontal probe inserted inside the sulcus; and the real thickness measured in mm with a calibrated needle. Agreement among the classif…
