Allotransplantation and autotransplantation of mature teeth in monkeys: the influence of endodontic treatment.

This study investigated the effect of endodontic treatment on root resorption of autotransplanted and allotransplanted mature teeth in unmatched monkeys. The material comprised 40 mature maxillary central incisors in 20 green Vervet monkeys (Cercopithecus aethiops). Teeth were either allotransplanted or autotransplanted in pairs of monkeys matched only for the size of the root.

In vitro antibacterial activities of eleven antibiotics against S. faecalis.

The in vitro antibacterial activities of penicillin, ampicillin, piperacillin, azlocillin, vancomycin, erythromycin, clindamycin, gentamicin, streptomycin, cefotaxime, and ceftriaxone against 198 S. faecalis strains were investigated, employing an agar dilution technique. Results were generally in accord with those of other studies.

In vitro susceptibility of diarrhoea producing gram negative enteric bacteria to sulfasalazine, 5-aminosalicylic acid, sulfapyridine and four quinolones. Brief report.

The in vitro susceptibility of diarrhoea producing Gram negative enteric bacteria to sulfasalazine, 5-aminosalicylic acid, sulfapyridine and four quinolones was investigated using an agar dilution method. All strains were resistant to 1600 micrograms/ml of sulfasalazine and 5-aminosalicylic acid. MIC range of sulfapyridine for Y.

In vitro susceptibility of Listeria monocytogenes isolated from human blood and cerebrospinal fluid. A material from the years 1958-1985.

The in vitro susceptibility of 156 strains of Listeria monocytogenes isolated since 1958 from human cerebrospinal fluid or blood to twelve antibiotics was determined by an agar dilution technique. Erythromycin (0.05), trimethoprim (0.

In vitro susceptibility of Pseudomonas aeruginosa from bacteremic and fibrocystic patients to four quinolones and five other antipseudomonal antibiotics.

The in vitro antibacterial activities of 4 quinolones, 4 antipseudomonal beta-lactam antibiotics and tobramycin were determined by an agar dilution technique against 206 clinical isolates of Pseudomonas aeruginosa. 176 isolates derived from blood cultures (BC), the remaining 30 were piperacillin-resistant strains from sputum of cystic fibrosis (CF) patients. The CF strains were more resistant to all drugs tested and differed greatly in susceptibility pattern from the BC strains.

Influence of carbon-dioxide tension and medium buffer concentration on medium pH and MIC values of erythromycin for Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 25923 in a micro-aerobic atmosphere.

The effect of an elevated carbon-dioxide tension on medium pH and MIC determination with erythromycin for Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 25922) was investigated in a micro-aerobic atmosphere, using an agar dilution method. During 30 h of incubation in an atmosphere containing approximately 6% CO2, 5% O2 and 89% N2, pH of uninoculated, as well as of seeded, blood agar plates decreased from 7.4 to 6.

In vitro susceptibility of Campylobacter jejuni and Campylobacter coli isolated in Denmark to fourteen antimicrobial agents.

The in vitro susceptibility of 95 recent Danish human clinical isolates of Campylobacter jejuni and Campylobacter coli to 14 antimicrobial agents was determined by an agar dilution technique. C. jejuni and C.

In vitro susceptibility of Campylobacter pyloridis to cimetidine, sucralfate, bismuth and sixteen antibiotics.

The in vitro susceptibility of recent Danish human clinical isolates of Campylobacter pyloridis to cimetidine, sucralfate, bismuth subsalicylate and sixteen antimicrobial agents was determined by an agar-dilution technique. Benzylpenicillin was the most active drug (MIC90 = 0.1 microgram/ml); ampicillin, erythromycin, gentamicin and ciprofloxacin were slightly less active.

Oral health care: more than caries and periodontal disease. A survey of epidemiological studies on oral disease.

A review is presented of the epidemiology of the common oral diseases other than dental caries and periodontal disease. It appears that conditions, such as masticatory dysfunction, traumatic dental and maxillofacial injuries, impactions and oral mucosal disease each normally affect one-quarter to one-half of populations examined. To plan and achieve total oral health care, it is, therefore, necessary to take these conditions into account.

Dental and skeletal maturity in adoptive children: assessments at arrival and after one year in the admitting country.

Seventy-one adoptive children from Asian countries, mainly Korea, were adopted by Danish parents. Height and weight were measured and dental and skeletal maturity assessed immediately after arrival and one year later. Increase in dental age was in complete concordance with the time interval between the two examinations.

Cryopreservation before replantation of mature teeth in monkeys. (II). Effect of preincubation, different freezing and equilibration rates and endodontic treatment upon periodontal healing.

The effect of cryopreservation in liquid nitrogen at -196 degrees C for 1 week was studied by histometric analysis of 60 mature teeth replanted in 10 green Vervet monkeys. The effect of preincubation in enriched tissue culture medium was also investigated. 2 different freezing rates were compared, and the effect of stepwise equilibration of DMSO was studied as well as the effect of root canal treatment.

The effect of apicoectomy before replantation on periodontal and pulpal healing in teeth in monkeys.

The effect of resection of the apical part of the root before replantation upon periodontal and pulpal healing was studied in 7 green Vervet monkeys (Cercopithecus aethiops) using teeth with incomplete and complete root formation. Maxillary central incisors, mandibular lateral incisors and first and second mandibular molars were used in this experiment. On one side, the tooth was extracted and replanted with an intact root while the contralateral tooth had 2 mm of the apex resected for the purpose of facilitating pulpal repair and eliminating resorption in the resorption-prone region of the root.
