Assessment of space changes in the lower dental arch after the premature unit loss of a primary molar: A randomized clinical trial.
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.
期刊介绍：
The International Journal of Paediatric Dentistry was formed in 1991 by the merger of the Journals of the International Association of Paediatric Dentistry and the British Society of Paediatric Dentistry and is published bi-monthly. It has true international scope and aims to promote the highest standard of education, practice and research in paediatric dentistry world-wide.
International Journal of Paediatric Dentistry publishes papers on all aspects of paediatric dentistry including: growth and development, behaviour management, diagnosis, prevention, restorative treatment and issue relating to medically compromised children or those with disabilities. This peer-reviewed journal features scientific articles, reviews, case reports, clinical techniques, short communications and abstracts of current paediatric dental research. Analytical studies with a scientific novelty value are preferred to descriptive studies. Case reports illustrating unusual conditions and clinically relevant observations are acceptable but must be of sufficiently high quality to be considered for publication; particularly the illustrative material must be of the highest quality.
