   <subfield code="a">INTRODUCTION: &quot;Singaw&quot; is a word commonly used by Filipinos to generally describe oral ulcerations that appear in the oral cavity. It is often painful and affects approximately 25% of the world?s population (Ahmed et al., 2011). There have been many studies conducted in other countries on the prevalence of oral ulcerations, but none has been found in the Philippines. This study will guide local information on oral ulcerations, which will help in determining its prevalence among a portion of Filipino patients, and identify relationships among various factors relating to its occurrence.</subfield>

  <datafield tag="520" ind1=" " ind2=" ">
   <subfield code="a">METHODS: A cross-sectional descriptive observational study was done on registered patients, whether walk-in or appointed, who came to the undergraduate clinics of the University of the Philippines College of Dentistry (UPCD) during regular clinical hours. Total enumeration was done from May 5, 2017 until the computed sample size of 175 participants had at least been reached. Oral examinations were conducted in the College and questionnaires were distributed among the undergraduate clinicians to record if their patients presented with an oral ulceration/s or not. Patients who presented with at least one ulceration as examined by the clinician during oral examination were asked to answer the questionnaire, which consisted of questions regarding patients? demographics, characteristics and symptoms of the ulceration/s present, the different factors which may have contributed to its occurrence, and how the patient managed the lesion/s. All questionnaires were submitted and results were tallied and analyzed at the end of each day, until at least 175 patients participated.</subfield>

  <datafield tag="520" ind1=" " ind2=" ">
   <subfield code="a">RESULTS: Out of the 189 participants examined during the period of data collection, 33 presented with oral ulceration/s. Out of those 33 participants: patients in the second decade (24%) and third decade of age (24%) were the most commonly affected; prevalence among females (51%) and males (49%) were almost the same; 39% was found among the ?poor? income class; 79% claimed to have never smoked, while 6% claimed to be light smokers. Familial history of oral ulcerations was also reported by 61%. Oral ulcerations were most commonly described as a small single lesion (67%), usually lasting 1-7 days (79%), and more prevalent along the lips (33%) and gingiva (33%), with 91% who complained of pain, and 70% who claimed difficulty in eating and/or speaking. The most common management option was salt water rinse (48%).</subfield>

   <subfield code="a">CONCLUSION: The prevalence of oral ulcerations among patients seen at the undergraduate clinics of the UPCD is 17.46% with 33 patients presenting with oral ulcerations out of the 189 participants during the period of data collection.</subfield>
