RESUMO
The aim of this study was to determine the profile of patients referred to a specialist oral medicine and oral pathology unit in Kuala Lumpur by reviewing clinical dental records received in Oral Pathology Diagnostic Service (OPDS) in Faculty of Dentistry, UKM from 2001 until 2010. A total of 547 archival biopsy clinical dental records were reviewed and analysed using SPSS version 17.0. Oral and maxillofacial diseases were frequently seen in female (1.3:1), young adults (30.0%) of Malay ethnicity (64.6%). Most of the acquired specimens were from dental specialists (n=451, 84.8%), particularly from oral and maxillofacial surgeons (OMFS) (n=349, 63.8%) compared to general dental practitioners (GDPs) (n=81, 14.8%). Almost all of the biopsy specimens were of soft tissue origin (n=462, 84.4%), derived from lining mucosa (n=197, 36.0%) and were biopsied excisionally (n=325, 59.4%) more often than by incisional biopsy (n=207, 37.8%). A large proportion of the oral and maxillofacial diseases were of reactive (n=188, 34.4%) and inflammatory (n=121, 22.1%) cause. Tumours are mainly benign (n=69, 12.6%) with only small cases are malignant (n=34, 6.2%). The most common histological diagnoses were accounted by mucocele (n=56, 10.2%), pyogenic granuloma (n=47, 8.6%), fibroepithelial polyp (n=38, 6.9%), radicular cyst (n=33, 6.0%) and periapical granuloma (n=29, 5.3%). This study characterizes the clinical profile of patients seen in our oral medicine and oral pathology unit. Present findings can be used as a reference to the clinicians and pathologists in effective patient management and organization in the future.

Despite the large number of published cases about oral and maxillofacial pediatric lesions, the literature is scarce on epidemiological studies regarding the prevalence of these entities. This study retrieved oral and maxillofacial pediatric lesions from the Center of Diagnosis of Oral Diseases (CDDB) at the Dental School of the Federal University of Pelotas (UFPEL), comprising a 20-year period (1983-2002). From the total of 9,465 biopsies received in this period, 625 (6.6%) were from children aged 0 to 14 years. Regardless of the histopathological diagnosis, patient data referring to lesion location, sex and age were collected. Diagnoses were grouped in 13 categories. As much as 89 percent of the cases occurred in patients aged 7 to 14 years (53% in females and 47 percent in males). Mucocele (17.2%) was the most common type of lesion, followed by dentigerous cyst (8.6%). In the category of odontogenic tumors, odontoma was the most frequent lesion (64.2%). Malignant lesions were observed in a small section of the sample (1.2%). Generally, the results of the present study are in line with those reported in the literature concerning the most prevalent lesions in the pediatric population. Most lesions were benign, and malignant lesions were diagnosed in a very small part of the sample.
