Assessment of Dentists' Knowledge of Space Maintainer Indications After Primary First Molar Extraction: A Cross-Sectional Study.

Background Space maintainer appliances can potentially reduce the need for extensive orthodontic treatment in the future for children. However, they can also lead to various complications, such as an increased risk of dental caries and gingival diseases. It is crucial for dentists to carefully evaluate a decision each child's specific situation before deciding whether to apply a space maintainer or not. This study aimed to evaluate the knowledge of dentists at Damascus University, both at undergraduate and specialist levels, regarding when space maintainers should be recommended. Methods A cross-sectional study was conducted involving 158 dentists (151 at the undergraduate level and seven at the specialist level). The questionnaire included 13 questions, covering demographic information and self-assessment, and 10 scenarios that are commonly encountered in clinical practice. Results The response rate was 50%. A majority of the participants (85, 53.8%) demonstrated inadequate knowledge. No significant correlations were found between knowledge level and gender (P = 0.853), practice experience (P = 0.171), or self-assessment (P = 0.383). Conclusions Most dentists exhibited a lack of knowledge about space maintainers, with no correlation identified between knowledge level, gender, practice experience, and self-assessment. It is recommended that educational curricula be updated to ensure that clinicians have a better understanding of when to use space maintainers in children.
