This study was conducted to investigate the effects of different IBA doses on rooting capacity of Cherry laurel (Prunus laurocerasus L.) types in greenhouse conditions under mist propagation unit in 2008 2009. This species has an economic and important value for medicinal and pharmaceutical industry. Determination of suitable conditions for cutting propagation of different types is too importan...

Various cultural practices, including the use of cover and rotational crops, composts, tillage systems, and others have been promoted as management options for enhancing soil quality and health. All cultural practices are known to directly or indirectly affect populations of soilborne pathogens and the severity of their resultant root diseases. Soil biology is a major component and contributes ...

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 lesion in a tooth. Control was defined as ...

This study evaluated the technical quality of root canal treatment (RCT) and detected iatrogenic errors in an undergraduate dental clinic at the College of Dentistry, Taibah University, Saudi Arabia. Dental records of 280 patients who received RCT between 2013 and 2016 undertaken by dental students were investigated by retrospective chart review. Root canal obturation was evaluated on the basis...

BACKGROUND   Lumbosacral selective nerve root blocks and/ or transforaminal epidural injections are used for diagnosis and treatment of different disorders causing low back and lower extremity pain. A clear consensus on the use of selective nerve root injections as a diagnostic tool does not currently exist. Additionally, the validity of this procedure as a diagnostic tool is not clear. OBJEC...

OBJECTIVES This study investigated cellular attachment to 6 root-end filling materials as a measure of the biocompatibility of the materials. MATERIAL AND METHODS Class I retrograde cavities were prepared in root slices and these cavities were filled with the test materials, and incubated with Balb/C 3T3 fibroblasts for 24 h. Root slices with the cavities left empty served as the controls. Th...

OBJECTIVE The presence of periapical radiolucency has been used as a criterion for endodontic treatment failure. However, in addition to the inherent limitations of radiographic examinations, radiographic interpretations are extremely subjective. Thus, this study investigated the effect of partial analysis of root filling quality and periapical status on retreatment decisions by general dentist...

The 4to 6-year outcome of orthograde retreatment was assessed for Phases I and II of the Toronto Study. In total, 523 teeth in 444 patients were retreated. With 395 teeth lost to follow-up and 25 extracted, 103 teeth (34% recall) were examined by two independent, blinded, calibrated examiners for outcome: “healed” (absence of apical periodontitis, signs, or symptoms) or “diseased” (presence of ...
