Replacement of missing teeth with fixed partial denture is high in demand, so high are the problems and failures of these prostheses if they are not maintained well. Objective: This study focused on determining the frequency of various grades of failures and the number of units involved in non-maintained fixed partial dentures in patients reporting to public sector dental hospital. Methods: A total of 216 patients, (both genders) having age ranging from 20 to 60 years, were clinically examined for failed fixed partial dentures. Various parameters of failed bridges including number of pontics and retainers were recorded by using a self-structured proforma. These prostheses were divided in six different grades as proposed by Manapallil. Mild, moderate and severe groups were used depending on the severity of failure. SPSS (version 23) was used for data analysis. Results: Out of 216 patients, a male (91) to female (125) ratio of 0.72 was found with a mean age of 47 years (SD ± 18.553). Failed prostheses in grades 1 to 4 were having a similar rate of failures (22% to 25%), while other grades of failure were less than 5%. Prosthesis service life ranged from 2 to 5 years. Almost 82% of prostheses had 4 or 5 pontics in the design of bridge with a mean number of pontics 5(SD ± 2.1) Conclusions: It was concluded that majority of failures were observed in mild and moderate groups in non-maintained fixed prostheses.
Objective: To determine the frequency of traumatic ulceration in denture supporting tissues following the provision of new complete dentures. Materials and Methods: This cross-sectional descriptive study was performed at the Prosthodontics Department of Khyber College of Dentistry, Peshawar over a period of 18 months. With the method of history and clinical examination and using a structured data collection sheet presence of traumatic ulcers in tissues underneath conventional complete dentures was recorded in 184 patients fulfilling the inclusion and exclusion criteria and who had not been previously wearing CD in both jaws. Patients were examined 3 to 4 days following the placement of their complete dentures, on their first recall appointment, for the presence of traumatic ulceration. Results: Patients (N=184) had mean age of 55.85±2.22 (SD) years with male to female ratio of 1:1.9. Patients returning with one or more traumatic ulcers 3 to 4 days following the placement of their complete dentures were 141 (76.6%) while 43 (23.4%) patients developed no ulcers. Ulcers were more commonly found in older age groups and in females. Conclusion: Traumatic ulcers were reported in majority of the patients who received conventional complete dentures. Thus the role of a prosthodontist does not end with the placement of the prosthesis. Regular follow up visits and adjustments need to be carried out following placement of complete dentures to ensure patient comfort and acceptance of the prosthesis.
Objective: To evaluate the frequency and severity of Non-carious cervical lesions (NCCLs) in patients reporting for provision of fixed dental prosthesis to the Department of Prosthodontics at Khyber College of Dentistry. Study Design: Descriptive Cross-sectional study. Setting: Department of Prosthodontics Khyber College of Dentistry, Peshawar. Period: March to September, 2019. Material & Methods: Patients of both genders above 18 years of age who reported to prosthetics department for provision of fixed dental prosthesis were included in this study. Frequency of Non-Carious Cervical Lesions was evaluated by visual and clinical examination. The severity levels of NCCLs were classified according to Smith-Knight tooth wear index (TWI) after assessment using William’s Probe and plain dental mirror. The data was analysed using SPSS version 21. Results: Participants were aged range from 18 to 50 years with a mean age of 46 years ± 2.3 SD. Among the total 149 patients evaluated, 89 (59.7%) had Non-Carious Cervical Lesions. Of these, 52 (58.4%) respondents had level 2 severity. The presence of NCCLs lesion was not associated with the gender and different age groups. Conclusion: High frequency of non-carious cervical lesions were found among local population. Thorough investigations of etiological factors is required for the prevention and managements of these lesions.
Objective: To determine the common locations of traumatic ulceration in denture supporting tissues following implantation of new complete dentures by prosthodontic postgraduate students.Methodology: This cross sectional study was conducted in the department of prosthodontics, Khyber College of Dentistry, Peshawar on 184 patients. Patients with newly placed dentures were examined after 3 to 4 days, on their first follow up visit, for the presence of traumatic ulceration. Pre-defined locations in the edentulous jaw were examined for the presence of traumatic ulcers. Data was entered and analyzed with the help of SPSS version 20. Results:The mean age was 55.85±2.22 years with male to female ratio of 1:1.9. Patients returning with one or more traumatic ulcers 3 to 4 days following the placement of their complete dentures were 141 (76.6%). More traumatic ulcers were found in tissues beneath mandibular dentures (n=,134 72.82%) compared to tissues beneath maxillary dentures (n=105, 57.06%). The most common sites to develop traumatic ulcers were the retromylohyoid area (n=73, 39.7%), maxillary vestibular sulcus between labial frenum and buccal frenum (n=52, 28.3%), maxillary tuberosity (n=51, 27.7%), mandibular vestibular sulcus at buccal shelf region (n=47, 25.5%) and the lingual sulcus at paralingual region (n=36, 19.6%). Conclusion:Traumatic ulcers in denture bearing tissues were reported in majority of the patients who received complete dentures. Retromylohyoid area was reported as the most prone area to the ulceration than others.
