Clinical Performance and Bacterial Plaque Counts Adjacent to Two Types of Space Maintainers
Ola Mohamed Ali Mahmoud Abd El-Geleel;
Abstract
The present study compared B&L SMand RibbondFRC SM, with regards to their clinical performance; their survival times, success rates and the gingival health of their abutment teeth, as well as; the bacterial counts in plaque adjacent to their abutment teeth.
The study sample comprised 30 children aged (6-8) years, who were admitted to the Pediatric Dentistry and Dental Public Health Clinic, Faculty of Dentistry, Ain-shams University, with bilateral mandibular first primary molars indicated for extraction mainly due to gross coronal destruction, periapical involvement and/or advanced root resorption (beyond repair).
The study was carried out in a split mouth design where B&L SM was placed in one quadrant, while Ribbond space maintainer was bonded to abutment teeth in the contralateral quadrant. Both appliances were evaluated over a period of 9 months (the study period), where patients were regularly recalled at 1, 3, 6 and 9 month’s intervals.
Ribbond space maintainer was constructed according to either of the following designs, in the first design, a single Ribbond fiber segment was bonded to the buccal aspects of the abutment teeth mesial and distal to the extraction span (Ribbond A), in the second design, double segments of Ribbond were bonded to the buccal and lingual aspects of the abutment teeth mesial and distal to the extraction span (Ribbond B).
Ribbond(B) showed the highest mean survival time (8.41 months) followed by Ribbond A (7.57 months) while B&L SM showed the lowest mean survival time (7.42 months). Yet, there was no statistically significant difference in the mean survival times between the three space maintainers.
