    Notes: Abstract The aim of this study was to evaluate clinically and radiographically the long-term results of endodontic therapy. A total of 172 mature teeth with periapical radiolucencies with and without symptoms were treated endoclontically using calcium hydroxide paste as the intracanal medicament and a calcium hydroxide containing root canal sealer. In 58 teeth, the dressing-was accidentally or intentionally extruded into the lesions. All cases were followed up for a period of 2–5 years. The teeth in which the dressing was extruded did not show a different healing pattern from the ones treated conventionally. The complete healing rate for all cases was 80.8% while incomplete healing had taken place in 7.6% of the cases.

    Notes: Abstract The aim of this study was to observe apical fool surfaces of teeth with chronic periapical lesions. Five premolars and three molars with radiographically demonstrable periapical lesions were extracted and fixed in 2.5% phosphate-buffered glutaraldehyde solution For 9 days. The apical 3-mm portion of 17 roots was removed and prepared for scanning electron microscope. Lacunar resorption zones were frequently observed on the root surfaces. Bacteria and yeast cells were detected in some of the lacunae. Periapical bacterial plaque with a smooth structure was present mostly around the main apical foramen. Cementum-like tissue deposits indicative of repair were seen adjacent to some resorption areas. Clastic cells lightly attached to crater-like depressions with linger-like projections were observed laterally on the specimens. Current research should be focused on new procedures to eliminate extraradicular microrganisms and periapical bacterial plaque in persistent periapical infections.

    Treatment of extraoral sinus tracts from traumatized teeth with apical periodontitis (1995)

    Notes: Abstract When a draining lesion is encountered on the skin of the face, an endodontic origin should always be considered in differential diagnosis. Non-surgical endodontic therapy, sometimes complimented by surgery, or extraction are the choices for the treatment of these cases. Three cases of extraoral sinus tract on the chin caused by necrotic pulp of traumatized lowrer anterior teeth are presented. A paste consisting of calcium hydroxide and barium sulfate powder mixed with glycerin was used. Usage of calcium hydroxide paste was advocated for rapid and successful treatment of extraoral lesions communicating with necrotic teeth.

    Observation of bacteria and fungi in infected root canals and dentinal tubules by SEM (1995)

    Notes: Abstract The aim of this study was to observe the root canal flora and possible penetration of microorganisms into dentinal tubules in teeth with necrotic pulps. Ten infected maxillary and mandibular molars with periapical lesions were extracted and fixed in 2.5% phosphate-buffered glutaraldehyde solution for nine days. After separation from the crowns, longitudinal grooves were cut in the roots, and they were split into two halves. The specimens were prepared for SEM. The root canals and the dentinal tubules of the fractured dentin were scanned systematically from the cervical to the apical area of the root. Cocci and rods were seen in 6 specimens. Penetration of bacteria into the dentinal tubules ranged from 10 to 150 μm. In 4 specimens, the root canals were heavily invaded by yeasts. The antimicrobial effect of routinely used endodontic disinfectants also on yeasts may be considered in persistent root canal infections.
