Periradicular repair after single-visit root canal treatment using sonic irrigant activation of teeth with apical periodontitis.

Objectives: This study aimed to explore whether using sonic irrigant activation during endodontic treatment favors periradicular repair in teeth with apical periodontitis.

Materials & Methods: One clinician treated 140 posterior (either premolar or molar) asymptomatic teeth with periapical lesions: 70 were randomly assigned to the sonic activation with EndoActivator (EA) group, and 70 were treated by conventional needle irrigation (CNI). Both groups underwent chemomechanical root canal preparation using 35/04 diameter rotary files and 2.

Is SWEEPS better than PUI in reducing intracanal bacteria and inflammation in cases of apical periodontitis?

To evaluate the efficacy of SWEEPS mode of the Er: YAG laser(SL) and passive ultrasonic irrigation(PUI) in the eradication of microorganisms and in the inflammation detection by IL-1β. Thirty patients with chronic apical periodontitis(AP) were allocated into two groups: Group SL-SWEEPS laser activated irrigation(n = 15) and Group PUI-passive ultrasonic irrigation(n = 15). Bacteriological samples were taken before(S1) and after chemomechanical preparation(S2), and then after final irrigation activation(S3).

The importance of mechanosensitive cell mediated prostaglandin and nitric oxide synthesis in the pathogenesis of apical periodontitis: comparative with chronic periodontitis.

Objectives: Mechano-sensitive odontoblast cells, which sense mechanical loading and various stresses in the tooth structure, synthesize early signaling molecules such as prostaglandin E2 (PGE2) and nitric oxide (NO) as an adaptive response. It is thought that these synthesized molecules can be used for the diagnosis and treatment of periodontal and periapical diseases. The aim of this study was to investigate the relationship between the severity of apical periodontitis (AP) and chronic periodontitis (CP) and serum (s) TNF-α, IL-10, PGE2 and NO levels, as well as PGE2 and NO levels in gingival crevicular fluid (GCF) samples.

Relationships among barodontalgia prevalence, altitude, stress, dental care frequency, and barodontalgia awareness: a survey of Turkish pilots.

Background: Gas expansion in body cavities due to pressure changes at high altitudes can cause barodontalgia. This condition may compromise flight safety.

Aim: To investigate relationships among barodontalgia awareness, dental visit frequency, and barodontalgia prevalence in civilian and military pilots operating at high altitudes.

Relationship of MMP-9 with the clinical course of apical periodontitis and the main bacterial species in the oral microbiota.

Bacterial products, host immune cells and cytokines have been reported to play an important role in the pathogenesis of apical periodontitis (AP). This study aimed to determine the main bacterial species in the microbiota as gram positive and negative and to compare the relationship between matrix metalloproteinase (MMP)-9 and tumor necrosis factor (TNF)-α with controlled patient groups. 60 patients with AP and extraction indication were included in the study.

Is XP-endo Finisher a better treatment option for its efficacy against intracanal bacteria for post-treatment apical periodontitis cases than EndoActivator?

To investigate the efficacy of the supplementary use of a rotary agitation method [XP-endo Finisher (XPF)] and sonically-activated irrigation [EndoActivator (EA)], using droplet digital PCR (ddPCR) on reducing the bacterial load in previously root canal treated teeth with apical periodontitis. Twenty patients with post-treatment apical periodontitis were allocated into two groups according to the irrigation activation method used: XPF and EA group. Total bacterial loads, as well as the amount of Enterococcus faecalis (E.

Is adrenomedullin upregulation due to apical periodontitis independent of periodontal disease?

To investigate the relationship between apical periodontitis [AP] severity and inflammatory markers [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-α), and Mid-Regional Pro Adrenomedullin (MR-proADM)] in patients with AP. A total of 162 subjects were divided into three categories: AP group (n = 80), periodontitis (P) group (n = 42), healthy control group (n = 40). The scoring of disease severity in 80 AP patients without any periodontal disease, using dental radiographs, was based on "The Abscess Score" (AS), as those having at least 1 tooth with AP and severity of PAI 3-4 were classified as AS 1 (mild); those with only1 tooth and severity of PAI 5 as AS 2 (moderate) and those having > 2 tooth with severity of PAI 5 as AS 3 (severe).

Microbial analysis of endodontic infections in teeth with post-treatment apical periodontitis before and after medication.

This study aimed to determine the intraradicular microbiota of previously root canal-treated teeth with apical periodontitis and to investigate the antibacterial effectiveness of different intracanal medicaments. Sixteen patients with post-treatment apical periodontitis were allocated into two groups according to the intracanal medicament used: calcium hydroxide (CH) and 2% chlorhexidine gluconate gel (CHX) group. Total bacterial loads, as well as the amount of Enterococcus faecalis (E.

Postoperative Pain Intensity after Single- versus Two-visit Nonsurgical Endodontic Retreatment: A Randomized Clinical Trial.

Introduction: The aim of this study was to evaluate postoperative pain after single-visit and 2-visit non-surgical endodontic retreatments with 2 different intracanal medicaments.

Methods: A total of 150 patients with asymptomatic root canal-treated teeth in need of nonsurgical endodontic retreatment were randomly divided into 3 groups (n = 50). Patients were selected randomly from among those without preoperative pain.
