Is Healing of Periapical Surgery Influenced by Endoscopic Findings Detected on the Cut Root Surface?

Purpose: An analysis was made of the association between the endoscopic findings of the sectioned root end surface and healing of the lesion 1 year after periapical surgery, although no studies appear to have analyzed them in relation to healing after periapical surgery.

Methods: A retrospective cohort study was made of patients subjected to periapical surgery between 2011 and 2019. After apicoectomy, the root end surface was examined, evaluating the number of canals, isthmuses, dentin cracks and craze lines, opaque dentin, and gaps between the filling material and the root canal wall.

Indications of the extraction of symptomatic impacted third molars. A systematic review.

Background: A literature review was made to determine when third molar (3M) extraction is recommended in symptomatic patients and when it is not recommended.

Material And Methods: A Medline (PubMed) and EMBASE search was made for articles related to indications for the extraction of 3Ms, published in the last 10 years and up until September 2018.

Results: The electronic search yielded 175 articles.

Hemodynamic variations and anxiety during the surgical extraction of impacted lower third molars.

Background: The surgical removal of an impacted third molar can cause patient anxiety. Such anxiety and the use of vasoconstrictor drugs and local anesthetics in turn can induce hemodynamic variations during the operation. A study is made of the variations in hemodynamic parameters (systolic and diastolic blood pressure and heart rate) and their correlation to patient gender and anxiety during surgical removal of an impacted lower third molar.

Comparison of digital protocols for the measurement of peri-implant marginal bone loss.

Background: The measurement of peri-implant marginal bone loss is currently carried out using digital methods of radiographic analysis assisted by various types of software. The purpose of this study was to compare the characteristics of three different softwares: specific radiology software for the development and visualization of radiological images in DICOM format (3Dicom Viewer®), advanced level software for professional editing of bitmap images (or raster graphics) (Adobe Photoshop®), and mid-level software for processing bitmap-type images, programmed in Java and in the public domain (ImageJ®).

Material And Methods: It was verified that the three softwares used are valid for the measurement of peri-implant marginal bone loss provided that the appropriate protocol is fulfilled.

Clinical and microbiological findings in patients with peri-implantitis: a cross-sectional study.

Objective: The aim of this study was to analyze clinical and microbiological characters in subjects and implants affected and not affected by peri-implantitis. Additionally, same features were analyzed also intra-individually, comparing healthy and diseased implants within the same subject.

Materials And Methods: A total of 534 patients who received at least 1 implant and coming to routine check-up or spontaneous visits at the University of Valencia were recruited.

Osteonecrosis of the jaws in patients treated with bisphosphonates.

The literature describes an increasing presence of bisphosphonate-induced osteonecrosis of the jaws (ONJ), characterized by the exposure for over 8 weeks of necrotic bone in the maxillofacial region, after bisphosphonate therapy, in the absence of prior maxillary radiotherapy. The present literature review examines the etiopathogenesis, risk factors, clinical forms, diagnosis, treatment and prevention of bisphosphonate-induced ONJ. In addition, a review is made of all the series involving over 15 patients diagnosed with this disorder between 1 January 2011 and 15 May 2011.

Localized vertical maxillary ridge preservation using bone cores and a rotated palatal flap.

The aim of vertical augmentation of the alveolar ridge is to restore resorbed alveolar ridges. This technique is critical to the placement of dental implants in a favorable position and the enhancement of restoration esthetics. The present report describes a technique for surgical preservation of the anterior maxillary process using maxillary bone from the surgical site and raising a soft tissue rotated palatal flap.

Bifid mandibular canal.

Purpose: To determine the incidence and characteristics of bifid mandibular canals.

Methods: A retrospective study was performed using panoramic radiographs of 2012 patients subjected to dental treatment in the Dental Clinic of the Valencia University Dental School (Valencia, Spain) between 1996 and 1999. The goal was to investigate the presence of double mandibular canals.
