Retrospective analysis of dental chair failures and usage patterns in academic dental clinics.

ABSTRACT: Dental chairs are essential for sustaining clinical care, yet their reliability in academic environments has rarely been quantified. This retrospective study, conducted across multiple clinics at Al-Andalus University for Medical Sciences (Tartous, Syria), integrated weekly usage logs, coded failure records, and equipment lifespan data to examine the relationship between workload and malfunction. Analysis revealed that prosthodontic and restorative clinics experienced the highest workloads and the greatest number of failures. Saliva ejectors, delivery systems, and control units accounted for most recurrent incidents, with a small subset of fault types responsible for the majority of breakdowns. The relationship between chair lifespan and fault frequency was generally weak, suggesting that
