531 - Evaluation of Facial Cellulitis of Odontogenic Origin: a Retrospective Review

Purpose: The objective of this study is to analyze records of pediatric patients treated by the University of Toledo College of Medicine Department of Dentistry for facial cellulitis of odontogenic origin. We evaluated age, gender, seasonal distribution, insurance, dental source of infection, duration of hospital stay, and history of previous restoration of the dental source of infection.

Methods: A targeted sample of dental records (operative reports, imaging if available and medical records) from patients consulted and treated in the operating room during the past 4.5 years were gathered and retrospectively reviewed.

Results: Thirty-six records were included for data analysis. The average age was 7.73 years; 41% female and 59% male. The spring season found the highest percentage of patients (36%). Eighty-one percent of patients utilized federal/state insurance. Right, lower face cellulitis of odontogenic origin was most commonly diagnosed (41.6%). The mandibular primary first molar was determined to be the most common source of infection (21%). The average length of stay in the hospital was 2.91 days. At least 8/43 teeth had previous restorations (P< .001).

Conclusion: Based on the cases treated by our dental service, the spring season produced the highest number of cellulitis cases requiring hospitalization. Males had a higher incidence of facial cellulitis. Primary teeth and teeth in the mandibular arch were found to be the most common source of infection, and at least 18% of the offending teeth had existing dental restorations. The majority of patients admitted for cellulitis utilized federal/state insurance.
