The prevalence of apical periodontitis (AP) in Europe has been reported to affect 61% of individuals and 14% of teeth, and increase with age. Likewise, the prevalence of root canal treatment (RCT) in Europe is estimated to be around 30-50% of individuals and 2-9% of teeth with radiographic evidence of chronic persistent AP in 30-65% of root filled teeth(More)
INTRODUCTION The aim of this study was to investigate radiographically the relationship of tobacco smoking and periapical status by using a retrospective case-control study design. METHODS The records of 79 controls and 79 age- and sex-matched cases were examined. Case was defined as a patient who has at least 1 radiographically detectable periapical(More)
AIM To investigate the expression of leptin in healthy and inflamed human dental pulp. METHODOLOGY Twenty-one pulp samples were obtained from freshly caries- and restoration-free extracted human third molars. In seven-third molars (inflamed pulp group), inflammation was induced prior to extraction. Pulp samples were processed, and leptin expression was(More)
INTRODUCTION The aim of this study was to investigate radiographically the prevalence of apical periodontitis (AP) and endodontic treatment in a sample of adult type II diabetic patients and control subjects. METHODS In a cross-sectional study, the radiographic records of 50 adult patients reporting a history of well-controlled type 2 diabetes mellitus(More)
The possible connection between chronic oral inflammatory processes, such as apical periodontitis and periodontal disease (PD), and systemic health is one of the most interesting aspects faced by the medical and dental scientific community. Chronic apical periodontitis shares important characteristics with PD: 1) both are chronic infections of the oral(More)
AIM  To determine the prevalence of apical periodontitis (AP) and the frequency of root canal treatment in a sample of Spanish adults. DESIGN  A descriptive cross-sectional study. SETTING  Barcelona, Spain. PARTICIPANTS  A total of 397 adult subjects, 49% males and 51% females. METHODS  Digital panoramic radiographs were used. Periapical status was(More)
INTRODUCTION After leptin receptor (LEPR) identification in hematopoietic, immune system, and other tissues, a role for leptin regulating inflammation and immune response has been accepted. This study aims to describe the possible expression of LEPR in healthy human dental pulp and to compare it with LEPR expression in inflamed human dental pulp. METHODS(More)
OBJECTIVE To analyse the influence of root canal instrumentation and obturation techniques on intra-operative pain experienced by patients during endodontic therapy. METHOD AND MATERIALS A descriptive cross-sectional study was carried out in Ponferrada and Sevilla, Spain, including 80 patients (46 men and 34 women), with ages ranged from 10 to 74 years,(More)
OBJECTIVES To investigate and compare postoperative pain after one-visit root canal treatment (RCT) on teeth with vital pulps using three different obturation techniques. STUDY DESIGN Two hundred and four patients (105 men and 99 women) aged 12 to 77 years were randomly assigned into three treatments groups: cold lateral compaction of gutta-percha (LC),(More)
STUDY OBJECTIVE To assess the usefulness of quantification of bronchoalveolar lavage (BAL) cells containing intracellular organisms (ICO) in the diagnosis of ventilator-associated pneumonia. DESIGN The reliability of cytologic analysis in comparison with the protected specimen brush (PSB) and BAL quantitative cultures has been assessed in a prospective(More)
