ABSTRACT
BACKGROUND:
Premature loss of primary teeth presents a significant challenge in oral health, with conflicting views on using space maintainers.AIM:
To assess mandibular arch space changes associated with premature lower primary molar (PM) loss with or without a space maintainer.DESIGN:
A randomized clinical trial with children (6-9 years old) with premature loss of a lower PM divided into two groups control group (CG), without a space maintainer, and intervention group (IG), with a space maintainer. Dental casts were measured at baseline, 3 months, and 6 months. Linear distance; intercanine width and length; and arch width, length, and perimeter were measured. ANOVA and t-test were applied (p = .05).RESULTS:
Twenty-six patients (mean 7.3 years; standard deviation [SD] 0.92) were included 14 in CG and 12 in IG. CG had a greater space loss (-0.9 mm; SD 0.45) than IG (-0.4 mm; SD 0.61) at 3 months (p < .05). No difference between the groups was observed after 6 months (p = .610). CG decreases space at 6 months, especially with the first permanent molars without intercuspation (-2 mm; SD 0.71; p = .007).CONCLUSION:
Premature lower PM loss resulted in reduced arch space loss after 6 months, regardless of a space maintainer use. CG showed more loss of space when the first permanent molars lacked intercuspal relationship.
