Apical surgery cuts off the apical root and the crown-to-root ratio becomes unfavorable. Crown-to-root ratio has been applied to periodontally compromised teeth. Apical root resection is a different matter from periodontal bone loss. The purpose of this paper is to review the validity of crown-to-root ratio in the apically resected teeth. Most roots have conical shape and the root surface area ...

INTRODUCTION Bacteria present in the apical root canal system are directly involved with the pathogenesis of post-treatment apical periodontitis. This study used a next-generation sequencing approach to identify the bacterial taxa occurring in cryopulverized apical root samples from root canal-treated teeth with post-treatment disease. METHODS Apical root specimens obtained during periradicul...

INTRODUCTION The purpose of the present study was to compare conventional intraoral periapical radiographs (PA) with limited cone beam computed tomography (CBCT) for evaluation of mandibular molars prior to apical surgery. The apical extent and homogeneity of the root canal fillings (RCF) as well as the number of root canals were examined. METHODS 38 molars with 75 roots were included in the ...

The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has be...

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 ...

Cardiovascular diseases are a major component of non-communicable and death, with thrombosis constituting the most common underlying pathosis three cardiovascular disorders: ischaemic heart disease (acute coronary syndrome), stroke venous thromboembolism (VTE). The introduction direct oral anticoagulants (DOACs) in recent years has necessitated more complex approach to periprocedural perioperat...

severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...

introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

INTRODUCTION The long-term outcome of apical surgery performed on root-filled teeth presenting with post-treatment apical periodontitis has been the subject of debate; therefore, current evidence is required to support the prognosis of this important procedure. The objectives of this study were (1) to assess the long-term outcome of apical surgery and (2) to identify significant outcome predict...

Abstract A 66–year–old woman presented to medical attention for low back pain, weight loss and evening fever about 2 weeks, with concomitant mood deflection. Blood cultures were positive Streptococcus mutans. Lumbar spondylodiscitis was found on spinal MRI splenic infarction abdominal ultrasound. The echocardiogram revealed the presence of vegetations aortic valve, which severely regurgitant, t...
