Amoxycillin with clavulanic acid and tetracycline in periodontal therapy

The effects of tetracycline and amoxycillin with clavulanic acid on the clinical parameters and subgingival flora of eight patients with rapidly progressive periodontitis was assessed. Subjects received either tetracycline 250 mg four times daily or amoxycillin 250 mg with clavulanic acid 125 mg three times daily for a period of 2 weeks together with subgingival scaling and root planning. Both treatment regimens produced significant reductions in bleeding on probing and probing pocket depths which were still present 16 weeks after the antibiotic therapy. A significant reduction in the mean percentage of black-pigmented Bacteroides spp., Fusobacterium nucleatum and anaerobic corroding bacilli was also obtained. Both treatment regimens were equally effective in reducing the clinical parameter and altering the subgingival flora. The MIC values for Bacteroides gingivalis (Porphyromonas gingivalis). Bacteroides intermedius (Prevotella intermedia) and F. nucleatum to amoxycillin with clavulanic acid remained constant throughout the period of investigation. The MIC values of these organisms to tetracycline increased.     

Studies on heat treatment for immediate reimplantation of resected bone

Extracorporeal heat treatment for devitalizing the tumour-infiltrated bone segment without destroying its regenerative potential was investigated for the purpose of immediate reimplantation of the resected bone. Effects of heat treatment on cell viability and bone inductive properties were studied in cultured tumour cells and animal models. Heat treatment at 65 degrees C for 30 to 120 minutes resulted in complete devitalization of cells, preserving osteogenetic properties of the allogenic bone implant in the rabbit. The results of the experiments indicate that this procedure has advantages in devitalizing the resected bone for its immediate reimplantation and justify clinical application. The clinical application of this heat treatment in 3 cases is presented.     

Statistical analysis of an urban population of 236 patients with head and neck pain. Part I. Patient profile.

A large group of patients (236) was examined for myofascial pain dysfunction syndrome. The parameters used for diagnosis of the syndrome were pain and tenderness in the head and neck muscles and temporomandibular joint, joint sounds, and limited function. It was found that the demographic profile of our patient population did not vary greatly from those reported previously in other studies. However, we did examine more details of the patients' backgrounds than any other single study. The relationships of age, sex, occupation, marital status, emotional stress, and head trauma were discussed.     

Dentist and laboratory: a "love-hate" relationship.

The author's intent has been to promote a close working relationship between the dentist and the technician. Certainly, McCracken was doing that when he said that he hoped they could "work together in proper sequence to develop restorations that are biologically and mechanically sound and to produce removable partial dentures that reflect continuous progress in prosthetic dentistry". That's the secret. The dentist and the technician should work together and in proper sequence. Too often dental education and the dental profession have seemed to espouse the idea that the technician must function as an automaton in the fabrication of removable partial dentures. The practitioner of general dentistry can certainly ask for ideas and suggestions from the technician and still control the ultimate outcome. The dentist can share thoughts with the technician to ameliorate the "love-hate" relationship and still be responsible for the removable partial denture treatment.
