Is periapical surgery follow-up with only two-dimensional radiographs reliable? A retrospective cohort type sensitivity study
2021
Background Two-dimensional (2D) radiographic techniques are commonly used for assessing lesion prognosis after endodontic surgery. The present retrospective cohort study analyzes the sensitivity and ability of different radiographic techniques in obtaining area and volume measurements of periapical lesions. Material and Methods Preoperative and follow-up (6-48 months) periapical and panoramic radiographs (index test) and cone-beam computed tomography (CBCT) images (reference standard) were selected from an endodontic microsurgery database. Sensitivity was analyzed independently by two examiners. The areas of the 2D radiographic images and CBCT volumes were studied using Itk-Snap software an…
Hemostatic agents used in apical surgery: a review
2011
Objective: A review was made of the current literature on hemostatic agents used in apical surgery in order to determine their effectiveness and adverse effects. Material and methods: The main search terms used were: endodontic surgery, apicoectomy, apical surgery, periradicular surgery, hemostasis, hemostatic agents, and bleeding control. The authors searched the Medline database for articles published up to 1 September 2010. Experimental and clinical studies comparing the effectiveness and/ or adverse effects of two or more hemostatic agents and published between 2000 and 2010 were included in the review. Results: Four studies were analyzed: two clinical studies and two experimental studi…
Influence of Hemostatic Agents in the Prognosis of Periapical Surgery: A Randomized Study of Epinephrine versus Aluminum Chloride
2017
Abstract Introduction Several variables have been associated with a better prognosis of periapical surgery. The aim of this study was to evaluate the influence of 2 hemostatic agents on the prognosis of periapical surgery at 12 months. Methods A prospective study was designed with 2 randomized parallel groups established depending on the hemostatic agent used: epinephrine or aluminum chloride. The analysis of the hemorrhage control was recorded as 0 (no hemorrhage control), 1 (slight but apparent intermittent bleeding persisted after application of the material), or 2 (complete hemorrhage control). At 12 months, periapical lesion healing was determined clinically and radiologically as succe…
Connexin 43, Bcl-2, Bax, Ki67, and E-cadherin patterns in oral squamous cell carcinoma and its relationship with GJA1 rs12197797 C/G
2022
To our knowledge, there is no useful and accurate prognostic biomarker or biomarkers for patients with oral squamous cell carcinoma (OSCC), a tumor with uncertain biological behavior, and unpredicTable clinical progress. The purposes of this study were: a) to determine the expresión profile of Connexin 43, Bcl-2, Bax, E-cadherin, and Ki67 in patients with OSCC; b) identify the GJCA1 rs12197797 genotypic composition. A cross-sectional study using genomic DNA and biopsy samples extracted from the oral mucosa with/without OSCC, older than 18 years, both genders, attended at Facultad de Odontología, Universidad Nacional Córdoba. Immunostaining for Cx43, Bcl-2, Bax, E-cadherin, and Ki67 and geno…
Treatment of apicomarginal defect with periapical surgery: A case report
2020
An apicomarginal defect can be explained as a total loss of buccal alveolus extending from the original crestal bone to the apex of the tooth. This study presents a case of an apicomarginal defect in a first left molar subjected to periapical surgery with vestibular cortex block replacement and A-PRF + membrane coating approximately one year ago. One-year clinical follow-up was performed, with no evidence of recurrence. This case report discusses periapical surgical treatment and the importance of an interdisciplinary approach to the management of teeth with apicomarginal defects. Key words:Periapical surgery, apicomarginal defect, A-PRF+, bone graft.
Comparison of diagnostic accuracy between periapical and panoramic radiographs and cone beam computed tomography in measuring the periapical area of …
2019
Background The aim of the study was compare the sensitivity and measurements obtained from teeth with apical lesions scheduled for periapical surgery using three different diagnostic methods: periapical radiography (Gendex Expert DC), panoramic radiography (Planmeca® Promax 3D Classic) and cone beam computed tomography (CBCT) (Planmeca® Promax 3D Classic). Material and methods This cross-sectional study involved 35 patients (45 teeth) scheduled for periapical surgery in which periapical radiographs, panoramic radiographs and CBCT scans had been obtained. The images were used to analyze the maximum vertical and horizontal dimension and the resulting areas of the periapical lesions based on t…
Retrograde filling material in periapical surgery: a systematic review
2021
Background Periapical surgery focuses on the treatment of teeth with persistent periapical lesions when orthograde root canal treatment fails. Although MTA® is the gold standard material for retrograde filling, Biodentine® - a tricalcium silicate-based cement - has been proposed in order to resolve several of its limitations. A systematic review has been carried out to compare the physicochemical properties of Biodentine® versus MTA® as root-end filling material in periapical surgery. Material and Methods An electronic search was conducted by two independent examiners during March 2020 in the Cochrane, PubMed-MEDLINE and Scopus databases. In addition, a manual search was made in specialized…
An update in periapical surgery
2006
Periapical surgery has largely improved at all levels due to new technologies provided by researchers throughout the last years. The aim of this article is to carry out a bibliographic revision of the last seven years. For this reason, we will analyse the studies published in Medline and the most important spanish dental magazines. The subjects to investigate are mainly based on the incorporation of ultrasonic root-end, which allow the performance of small and adjusted retrograde cavities; as well as the new filling materials. We also include magnifying glasses or surgical microscope to the work material, plus surgical laser and the application of guided tissue regeneration.
Materials and prognostic factors of bone regeneration in periapical surgery: a systematic review
2013
Objectives: Analyse the effectiveness of different materials and techniques used in guided tissue regeneration (GTR) applied in periapical surgery, comparing the success rate obtained in 4-wall defects and in through-and-through bone lesions as well as to establish prognostic factors. Material and Methods: A Cochrane, PubMed-MEDLINE and Scopus database search (October 2012 to March 2013) was conducted with the search terms “periapical surgery”, “surgical endodontic treatment”, “guided tissue regeneration”, “bone regeneration”, “bone grafts”, “barrier membranes” and “periapical lesions” individually and next, using the Boolean operator “AND”. The inclusion criteria were the use of GTR (bone …
Prognostic factors on periapical surgery: A systematic review
2015
Background Analyze the most important prognostic factors when performing periapical surgery and compare the success rates of distinct authors. Introduction Periapical surgery is an approach to treat non-healing periapical lesions and it should be viewed as an extension of endodontic treatment and not as a separate entity. Material and Methods A search of articles published in Cochrane, PubMed (MEDLINE) and Scopus was conducted with the key words “prognostic factors”, “prognosis”, “periapical surgery”, “endodontic surgery” and “surgical endodontic treatment”. The inclusion criteria were articles including at least 10 patients, published in English, for the last 10 years. The exclusion criter…
