Location and frequency of traumatic mucosal ulcerations following delivery of complete dentures in edentulous patient treated in Tabriz dental school in 1387-1388

Abstract

Treatment of edentulous patients is not finished with the delivery of complete dentures but the dentist 's care to patient is continued for some time. Especially the first days after delivery is very important, because it is the period of adaptation of patient with his/her new dentures. In this phase, the dentist's care to patient has an important role in success or failure of treatment. Purpose: To determine the recognition of the most prevalent location and frequency of traumatic ulcerations after delivery of dentures. Materials and Methods: 60 patients with acceptable conditions were selected from the patients treated in the department of removable prosthesis of Tabriz Dental School in educational year of 2008-2009. The dentures made by the common way for the chosen patients in the department of removable prosthesis. After delivery of the dentures, all patients were examined from the day after delivery till complete omission of problems. Each time, the need for adjust and the location of ulceration were noted. Statistical analysis, including descriptive statistics and CHI2 analysis, is used to study the relationship between ulcerations and the days after delivery, as well as the relationship between ulcerations and gender. P<0.05 was statistically significant. Results: 85.8% of patients required adjustment at first visit because of mucosal ulcerations. 75% at second visit, 64.1% at third visit, 49% at forth visit, 18.3% at fifth visit and 6.6% at sixth one. Totally, upper denture after forth visit and lower denture after sixth visit, didnEt need any adjustments because of ulcerations. Most frequently injured areas at upper jaw were posterior palatal seal at soft palate (27%), buccal slop of edentulous ridge (13.8%) , distobuccal sulcus (13.1%) and labial frenum (9.9%) . In the lower jaw, the most frequently injured areas were the retromylohyoid area (48.6%) , buccal sulcus adjacent to buccal shelf (9.8%) , retromolar pad (9.5%) and labial fernum (8.1%) . The least frequently injured areas at upper jaw were hard palate and intermaxillary suture (0%), incisive papilla and rugae (0.65%), tuberosity (2.9%) and buccal and labial sulcuses (4.6%). In the lower jaw, the least frequently injured areas were below the tongue and torus (0%), labial sulcus and mylohyoid area of lingual sulcus (1.2%), buccal frenum and buccal shelf (2.1%) . The number of dentures requiring adjustment at different days were statistically significant. (P<0.001). Thus, the difference between number of mucosal ulcerations at certain anatomic areas of upper and lower jaw, wasnEt significant with exact fisher, Test (p>0.05). Also, the results indicate that, the frequency of lower dentures need to adjust at all visits after delivery is more than upper ones (P<0.001). Conclusions: Treatment of edentulous patients is not finished with delivery of dentures and patient care is an important phase in patients treatment and denture fabrication. Since, denture-induced irritations appear most often in borders, true border extensions especially at border molding stage and use of pressure indicator paste at delivery phase and other visits, has an important role in diminishing tissue ulcerations and comfort. As a part of treatment protocol, the patients must be trained to use dentures truly and to eat softer foods.
