This study was undertaken to qualitatively analyze patients' profiles and to identify the sociodemographic and oral health factors associated with emergency visits to the public dental service in Montpellier, France. A cross-sectional survey was conducted in the dental care service at Montpellier Hospital. Socioeconomic and clinical variables were compared between the patients using the emergency dental care service and those utilizing the general dental services, which were by appointment. An evaluation of the results indicated that younger patients and people from lower socioeconomic groups used the emergency dental service more frequently. Unemployed people (OR = 1.60) and manual workers (OR = 1.86) were also more likely to use this service. The need for treatment of caries was significantly higher in the group that used the emergency service. It appeared that the two groups of patients had different attendance behavior and showed significantly different socioeconomic and oral health status.
