Effects of behavioral self-management on oral hygiene adherence among orthodontic patients.

Twenty-nine new orthodontic patients and 30 experienced orthodontic patients received either behavioral self-management of toothbrushing and mouth rinsing or an experimental regimen that consisted of prompting by the orthodontist to brush and rinse regularly plus instructions to turn in home care materials during orthodontic visits. Several sets of data showed uniformly high rates of brushing and rinsing among all four groups of subjects. Several data sets also showed significant improvements in oral health status among all four groups. Substantive and methodologic directions for future research are delineated.

Effects of suctioning devices on oral fluoride retention.

This study examined the effectiveness of suctioning devices in reducing oral fluoride retention after professional 4-minute applications of a 1.23% fluoride gel. The value of patient expectoration was also evaluated in the child subjects. The suction devices were statistically significant adjuncts in reducing oral-retained fluoride in all cases; however, the oral-retained fluoride doses after the suctioning procedures were still distinct in both adults (10.3 +/- 2.3 mg) and children (7.7 +/- 1.0 mg). These amounts of oral-retained fluoride would result in substantial elevations in body fluid fluoride concentrations. One minute of expectoration after the suctioning procedures in children was a statistically significant method of further reducing oral fluoride retention to a clinically acceptable level (1.6 +/- 0.5 mg). We recommend that suction devices be used during topical fluoride treatments, but most importantly that the patients be requested to expectorate thoroughly after topical treatment.

Oral fluoride retention with thixotropic and APF gels and foam-lined and unlined trays.

Ten child volunteers each received four topical fluoride applications using different techniques. The amounts of fluoride applied, recovered from the mouth, and retained in the mouth were calculated for each treatment. The value of patient expectoration following topical F treatment was also evaluated. The tray system with an absorptive liner significantly reduced the amount of gross oral-retained fluoride (p less than 0.01). Expectoration following topical treatment with either an APF or thixotropic gel was a significant adjunct in reducing the net oral-retained F dose (p less than 0.01). When expectoration is done following a topical F treatment, a thixotropic gel may be an added advantage in reducing oral F retention and ingestion. We recommend that suction devices be used during a topical F treatment, but most importantly that the patient be requested to expectorate thoroughly following topical treatment.

Oral fluoride retention following various topical application techniques in children.

Eight child volunteers received routine APF gel topical fluoride applications using four different application techniques. Each child received a total of four topical fluoride applications, and all applications were separated by at least one wk. The amounts of fluoride applied, recovered from the mouth, and retained in the mouth were calculated for each treatment. Tray systems with some form of absorptive liner resulted in significantly less oral-retained fluoride after the four-minute application procedure (p less than .01). The value of patient expectoration following topical fluoride treatment was also evaluated, and was a significant adjunct in reducing the net oral-retained fluoride dose in each instance (p less than .01).

The effects of maxillary expansion using a quad-helix appliance during the deciduous and mixed dentitions.

Ten subjects, five in the deciduous dentition and five in the mixed dentition (mean age = 6 years 9 months), had functional posterior cross-bites successfully corrected with fixed lingual arch wire expansion appliances of the quad-helix design. The appliance, in the context of "early" treatment, produced midpalatal suture separation on each subject as evidenced on occlusal radiographs. While the relative orthopedic and orthodontic changes were not determined, the maxillary intermolar and intercanine transverse measurements showed significant increases in all subjects, with mean values of +5.3 mm. and +4.1 mm., respectively. The active phase of treatment averaged 30 days and 1.1 adjustments for the desired expansion to be achieved. Incorporating a standard 6-week retention period, the total appliance wear time had a mean value of 75 days. Following a 3-month postretention adjustment period, relapse of the intermolar and intercanine transverse dimensions presented mean decreases of -1.5 mm. and -1.9 mm., respectively. The relapse potential was successfully compensated for by overexpansion of 2 to 3 mm. during the active phase of treatment. No significant differences were demonstrated between the deciduous- and mixed-dentition groups during the course of maxillary expansion with the quad-helix appliance.

The biologic availability of fluoride from alginate impressions and APF gel applications in children.

Ten child volunteers received routine alginate impressions and APF gel topical applications during separate visits. Whole saliva, urine, and surface enamel fluoride concentrations were measured before and after these procedures. Significant increases in salivary, urinary, and enamel fluoride concentrations were observed following APF gel application but only in whole saliva following alginate impressions.
