Nonlinear dynamical analysis of the effect by six stimuli on electroencephalogram.

The present study investigated the search by correlation dimension (D2) for the effect of six stimuli (sucrose, spearmint, gum-base chewing as a voluntary movement, and three combinations of these stimuli) on EEG findings. Twenty normal adult subjects received sucrose, spearmint oil, gum-base alone, and three combinations of these stimuli. EEG recordings were obtained while the subjects rested quietly with their eyes closed, as the following procedure: section I, 1 minute at rest; section II, first 5-minute recording (control record); session III, each stimulus affecting for 3 minutes; session IV, 1 minute at rest; session V, 5-minute recording (poststimulus record).

A comparison of the gingival health of children with Down syndrome to healthy children residing in an institution.

The purpose of this study was to compare the onset and severity of gingivitis in children with Down syndrome, when compared to a healthy control group of children. The subjects included 41 children with Down syndrome ages two to 14 years (mean age: 7.6 years) and 112 age-matched healthy controls.

Effect of periodic preventive care on the progression of periodontal disease in young adults with Down's syndrome.

Objectives: To examine the effect of periodic preventive care on the progression of periodontal disease in 24 young adults with Down's syndrome (DS) (mean age+/-SD: 20.8+/-5.6 years)

Material And Methods: Subjects were divided into two groups: 13 subjects who had frequently visited our clinic (mean interval between visits: 3.

Mutans streptococci, lactobacilli in saliva and acidity from organisms in dental plaque: changes after restorative treatment.

The effect of restorative dental treatment was evaluated on mutans streptococci and lactobacilli in saliva, as well as acid production by plaque bacteria. We used semiquantitative culture kits at time points up to 6 months following treatment. Changes in eating habits and oral hygiene during the study period were ruled out using a questionnaire.

Time dependent changes of variables associated with malocclusion in patients with Duchenne muscular dystrophy.

Time dependent changes of parameters associated with malocclusion in patients with Duchenne muscular dystrophy (DMD) were examined in four dental developmental stages in 34 patients. We adopted activities of daily living (ADL) score, dental arch, craniofacial morphology, and electromyograms of the masseter and temporalis muscle as parameters. A comparison was made with the results in DMD subjects to data from healthy subjects with normal occlusion reported in the literature.

Preventive effects by intensive restorative treatment against caries in children.

The caries preventive effect of intensive treatment of existing caries was studied in children less than 7 years old living in a district without a dentist. The methods consisted of intensive restorative treatment provided by a pediatric dentist in three stages as follows: Stage I (n=70), two years before initiation of intensive treatment; Stage II (n=80), at initiation of long-term intensive treatment, and Stage III (n=92) three years after initiation of intensive dental treatments. The results were that experience and severity of dental caries and secondary caries rates were significantly lower in stage III than in stage I or II in six year olds.
