[Nerve dysfunctions following mandibular surgery on an outpatient basis].

The extent and reversibility of any functional impairment of the inferior alveolar and lingual nerves are important criteria for establishing the indication for microsurgical reconstruction. Postoperative dysfunctions were observed by 31.4% of 384 patients operated in the posterior segment of the lower jaw. In more than half of these cases the dysfunctions disappeared after 8 weeks. After 6 months the remission tendency was very slight. After a mean 4 years following operation 6% of the patients reported subjective disorders. Impaired functions were demonstrated objectively in 11.4% of the cases. The phenomenon of adaptation seems to play an important part. Only 2 patients would have desired further surgical treatment.

[Cephroxadine--a new antibiotic. Clinical experience].

Cephroxadine is an orally active cephalosporin of third generation. The most important characteristics are: 1) bacterial cell wall synthesis inhibition during active multiplication; 2) wide spectrum of action, including Gram+ and Gram- bacteria and also penicillinase and beta-lactamase producers; 3) possibility of oral administration, quick assimilation and daily moderate dosage (500 mg/12 h). This antibiotic was tested on 71 patients to prevent and resolve dental pre-and post-operating infections. In all tested cases Cephroxadine was very effective and resolved well symptoms on second day, generally. Moreover no patient had any collateral effect to justify interruption of therapy.

[Developmental radicular groove as a cause of endodontic failure].

A clinical case of apical injury on an upper lateral incisor with endodontical and surgical failures in its treatment is presented. Extraction of the incisor and its study at the stereoscopic microscope showed the existence of a developmental groove running from the cingulum to the end of the root, establishing a communication between the crevice and the apical part of the tooth. Bacterial infection through the groove could provide an explanation for treatment failure.
