Benign masses of the oral mucosa. Retrospective epidemiologic study of 250 cases in the Clinic of Oral & Maxillofacial Surgery Department of the Univeristy of Athens School of Dentistry.
Summary:
Objective: To analyze the frequency, types and distribution of benign oral soft tissue masses, as reported in the Department of Oral & Maxillofacial Surgery of the Dental School of the National Kapodestrian University of Athens, to study the clinical characteristics, to review the literature and compare these data with those of previously reported studies.
Material and method: This is a retrospective study of 250 histologically diagnosed benign masses of the oral mucosa. The records of the Department of Oral & Maxillofacial Surgery were reviewed and analyzed for patients with benign oral soft tissue masses, recieved during a 6-year period (2004-2010). Data was compiled for each case, documenting information relating to age, gender, and the characteristics of the lesion (site, color, size, surface, consistency and base).
Results: Of all the lesions studied, traumatic fibroma was the most common lesion, constituting 17,2% of the cases, followed by extravasation mucocele (13,6%). In the study of prevalence of benign oral soft tissue masses, no differences were found for age; however there were differences according to gender, finding a greater prevalence of extravasation mucocele in men (at a ratio of 2:1), and of epulis fissuratum in women. Pyogenic granuloma was the most common benign neoplasm in all age groups. The oral sites commonly affected by benign oral soft tissue masses were the gingival (30%), buccal mucosa (24,8%), lower lip (15,2%), floor of the mouth (9,6%) and tongue (8%) in a descending order. Benign oral soft tissue masses mostly presented a similar colour to the normal mucosa (48,4%), and a smooth surface (61,6%). Connective tissue lesions presented with an elastic consistency on palpation, however this finding is not statistically significant for this type of lesion. On evaluating the base of the lesions and relation to neighboring tissues, statistically significant differences were found for traumatic fibroma, which mostly presented as a sessile base, while the majority of peripheral ossifying fibroma and pyogenic granuloma had a pedunculated base.
Conclusion: Some of the features of benign oral softh tissue masses are partially in harmony with those of published literature and some are different. Comparing the overall prevalence rates of the various benign oral soft tissue masses with the published studies is complicated due to different ways of categorization and methology. Further surveys are needed to define the epidemiology of benign oral soft tissue masses. Knowledge of the frequency and presentation of the most common benign oral soft tissue masses is beneficial in developing a clinical diagnosis.
