Custom mouthguards, especially those fabricated with the injection molding technique of Corflex Orthodontic, were shown to be superior to standard mouthguards in terms of their comfort and users' subjective impressions of their protective function.

The usability of custom mouthguards, especially the ones molded from Corflex, was rated much higher than that of self-adapted mouthguards. Thus, it is the custom mouthguards that should be suggested to and fitted in patients prone to orofacial injuries.

Mouthguards do not significantly disturb basic functions of the stomatognathic system. Standard Porida mouthguards were shown to have the most unfavourable effect on oral functions.

Specimens from 300 patients were studied using five to nine aerobic and anaerobic culture media, including five that were hypertonic, Groups studied included fever of unknown origin, suspected endocarditis, endocarditis during therapy, bacteremia during therapy, abscess and cellulitis, presumed infectious arthritis, renal transplantation during rejection, collagen disease, sarcoidosis, lymphoma, and colitis. Isolates in hypertonic media were reverted to parent form by agar passage. In only 5% of these selected cases were organisms found in hypertonic, but not conventional, media that appeared on the basis of repeated isolation and/or serological studies to come from the patient. Nine of the 16 appeared to be of major significance. The two groups in which use of highly enriched, hypertonic media seemed most helpful were suspected endocarditis and undefined meningitis with negative cultures using standard media. The most effective of the hypertonic media used was 0.3 M sucrose in brain heart infusion with 20% horse serum. In most instances, the organism grew only in the hypertonic sucrose, and in most cases it appeared in conventional rather than aberrant form. Hypertonic media, especially 0.3 M sucrose, are of substantial helpin a small number of carefully selected cases.

The obtained results can advocate local compensatory mechanism in saliva in response to increased oxidative stress associated with primary tumour. ORAC can become an additional factor in head and neck SCC prognosis, but further investigation is required.
