1/4. The down syndrome patient in dental practice, Part II: clinical considerations.

    down syndrome (DS), or trisomy 21, is a genetic disorder which results in intellectual impairment, typical craniofacial features and a wide spectrum of phenotypic abnormalities (reviewed by Kieser et al, 2003). Despite a large volume of research into this condition, its prevalence remains high (1 in 700 live births - Serra and Neri, 1990; Reeves, 2000). This, together with a notable increase in life expectancy (Pilcher, 1998), improved health care and a greater degree of integration into society in new zealand has resulted in an increased demand for dental care.

2/4. The use of botulinum toxin-a in the treatment of severe bruxism in a patient with autism: a case report.

    This case report describes an alternative method for reducing bruxism in a special needs patient who was not a candidate for an intraoral appliance. bruxism is often seen in patients with special needs and can result in excessive dental wear, temporo-mandibular joint pain, avulsion of teeth and other problems. Current methods of management are not typically effective in this population because most require patient compliance. An 11-year-old male diagnosed with autism and Bannayan-Zonana syndrome received bilateral injections of botulinum toxin type-A (Botox Allergan Pharmaceuticals, Irvine CA) in the masseter muscle. The patient's condition was followed up via post-operative telephone interviews with the parents for 60 days. A reduction in the frequency and severity of bruxism was reported. The only side effects noted were soreness at the injection site and mild, temporary drooling. Although further research is required to determine the optimal doses and injection frequency, botulinum toxin type-A appears to be an alternative method for controlling bruxism in the special needs population.

3/4. Reducing severe diurnal bruxism in two profoundly retarded females.

    Several diurnal audible teeth grinding (bruxism) was found to affect 21.5% of a profoundly retarded population. However, no previous research has treated bruxism in retarded individuals. In the current study a multiple baseline across subjects design was used to assess the effectiveness of contingent "icing," brief contingent tactile applications of ice, as a treatment for bruxism. Three 15-minute treatment periods and two 5-minute generalization periods were conducted 5 days per week. One resident displayed a 95% reduction in the percentage of intervals during which bruxism occurred during treatment periods and a 67% reduction during generalization periods. The other resident displayed a 94% reduction in the percentage of intervals during which bruxism occurred during treatment periods and a 53% reduction during generalization periods.

4/4. A more efficient biofeedback procedure for the treatment of nocturnal bruxism.

    The study describes a noval approach in the use of a conditioning procedure for the treatment of nocturnal bruxism. The effectiveness of the procedure is demonstrated through its application with two nocturnal bruxists in controlled study designs. Subject 1 received several variations of this procedure and the result indicated that using a loud tone which she manually reset after awakening was the most effective approach to this treatment. The second study was designed to compare the effectiveness of relaxation training to the conditioning technique. Subject 2 failed to show any decrease in her bruxing behavior when taught relaxation. However, she showed immediate decreases in both frequency and duration of bruxing responses when treated with the biofeedback procedure. The need for future research in this area is discussed with emphasis on the development of low cost, home treatment units.
