Regenerative endodontic procedure combined with apical surgery of a necrotic permanent incisor with extensive periapical lesion using plasma rich in …
2021
Background The aim of this case report is to describe the step-by step and outcomes of a treatment approach which simultaneously combines a Regenerative Endodontic Procedure (REP) and apical surgery using PRGF as treatment of a post-traumatic necrotic permanent central incisor with extensive periapical lesion and undeveloped apex in a 16 years-old patient. Case description A 16 years-old patient with an extensive periapical lesion in the maxillary central incisor was treated with a combination of REP and periapical surgery in the same visit. A Bi- antibiotic paste (BAP) was used to priorly disinfect the canal, which was posteriorly sealed with MTA placed over a PRGF clot at the same time th…
A retrospective study of the prevalence and characteristics of dens invaginatus in a sample of the Turkish population.
2012
Objective: The purpose of this study was to assess the prevalence of dens invaginatus and to classify the types of dens invaginatus in a sample of the Turkish population.. Study Design: A retrospective study was performed using periapical and panoramic radiographs of 5355 patients who presented to the Department of Oral Diagnosis and Radiology at the Ondokuz Mayıs University Dentistry Faculty between January 2009 and December 2010. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Results: Dens invaginatus …
Inflammatory implant periapical lesion: etiology, diagnosis, and treatment--presentation of 7 cases.
2008
Purpose To investigate implant periapical lesions, and to describe their treatment. The hypothesis of this evaluation is that implant periapical lesions are disorders of the area surrounding the apex of a dental implant, and that their etiology can be multifactorial (ie, vascular impairment, vascular ischemia, overheating of bone during drilling, and implant surface contamination). The diagnosis is based on the clinical manifestations and x-ray findings. The x-ray findings usually involve a periapical radiotransparency. Materials and Methods Seven patients with implant periapical lesions (3 in the upper jaw, and 4 in the mandible) after implant placement are described. All patients reported…
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…
Oral mucositis. Is it present in the immunotherapy of the immune checkpoint pd1/pd-l1 against oral cancer? A systematic review
2020
Background Oral mucositis (OM) is a painful lesion that takes place in the mucosa of the oral cavity, usually its etiology is associated with drug therapies in cancer patients. It is presented as well-defined ulcers whose painful symptomatology sometimes implies the suspension of oncological treatment or parenteral feeding, being therefore an important adverse effect, marking the evolution of these types of therapies against cancer. The present work aim is to know the prevalence of oral mucositis in oral cancer immunotherapy compared to its prevalence in standard therapy. Material and Methods A protocol was developed for a systematic review following PRISMA® guidelines and a focused questio…
Oral Infections and the Risk of Mortality in the Iron Age
2008
Medically unattended oral abscesses may spread to their surrounding area or even throught the entire body. Depending on the individual`s constitution, such processes may lead to a life-threatening situation or death. (Pre)historic case studies deliver more information about distribution and adverse effects of oral infections and the risk of mortality. In this particular case report an iron aged skeleton of a 35- to 45-year-old woman from Eulau (Naumburg/ Saale, Germany) shows multiple periapical lesions and their effects on the viscerocranium. Furthermore, alterations on the long bones can be associated with chronic inflammation processes.
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…
The post-endodontic periapical lesion: Histologic and etiopathogenic aspects
2007
Apical periodontitis is produced in the majority of cases by intraradicular infection. Treatment consists in the elimination of the infectious agents by endodontia. Even when carrying out a correct cleansing and filling of canals, it is possible that periapical periodontitis will persist in the form of an asymptomatic radiolucency, giving rise to the post-endodontic periapical lesion. The chronic inflammatory periapical lesion is the most common pathology found in relation to alveolar bone of the jaw. From the histological point of view, it can be classified as chronic periapical periodontitis (periapical granuloma), radicular cyst, and as scar tissue. The most frequent is the periapical gr…
Racial disparity and prognosis in patients with mouth and oropharynx cancer in Brazil.
2022
Oral and oropharyngeal cancer (OPC) is an important cause of morbidity and mortality worldwide. Populations in situations of social vulnerability tend to have higher incidences of cancer, a higher proportion of late diagnosis, greater difficulties in accessing health services, and, consequently, worse prognosis. The aim of this study was to evaluate the relationship between race/skin color and OPC prognosis in Brazil. This is a cross-sectional epidemiological study using OPC data from the National Cancer Institute between the years 2000 and 2019. The selected variables were: gender, race/skin color, age, education, smoking and alcohol consumption, stage of the disease and disease status at …
Update in dental implant periapical surgery
2006
La lesión periapical implantaria es una patología infecciosa-inflamatoria localizada alrededor del ápice del implante. Puede ser provocada por diversas causas, entre ellas: la contaminación en el momento de la instrumentación, el sobrecalentamiento óseo y la presencia de una patología preexistente en el hueso. Su diagnóstico es sintomático y radiográfico, y puede observarse una imagen radiolúcida alrededor del periápice. Clasificamos las lesiones según el momento evolutivo en lesión aguda (no supurada y supurada) y crónica o absceso periapical. El tratamiento de esta patología es la cirugía periapical con legrado e irrigación en la fase aguda; y la extracción del implante cuando se involucr…
