Background: The rehabilitation of edentulous patients requires acrylic resin complete dentures to fulfil their functional and esthetic needs. Fractures of dentures are one of the commonest complaints around the world. Aim: To evaluate the frequency of acrylic complete denture fractures among edentulous patients and find out their association with certain variables. Methodology: A cross sectional observational study was carried out in Prosthodontic department of Lahore Medical and Dental College, Lahore from 26th March 2020 to 26th September 2021. A total of 58 completely edentulous patients reported with fractured acrylic dentures were selected. Patients were evaluated both intra and extra orally to find out the cause and site of fracture. Various parameters namely, denture age, fracture sites, gender were statistically evaluated to find out their relationship with denture fracture. Results: Results showed that male patients; 56.9% were presenting more with fractured dentures than female; 43.10%. In males the midline denture fractures were most commonly seen 45.5%, whereas in females’ fracture at premolar area was commonly observed 28.0% however no statistical dependance between fractured dentures sites and gender was found. Denture fractures were most prevalent in mandibular arch 50% as compared to maxillary 39.7%. Mid line fracture was the commonest site observed in both maxillary 30.4% and mandibular arches 31.0%. Insignificant association between fracture sites and dental arches was seen. Maximum denture fractures were recorded in first 2 years of denture fabrication 55.2%. The most frequent cause of denture fracture was accidental falling 34.5%. Conclusion: The frequency of complete denture fracture is more in mandible as compared to maxilla and the main reason is patients’ negligence. The study also showed midline fracture of dentures to be the most frequent site of denture fracture. Keywords: Acrylic dentures, Complete dentures, Edentulism, Edentulous, Prosthesis, Tooth loss,

Aim: To evaluate different smile characteristics among dental students and find out gender- based association. Study design: Cross sectional observational study. Place and duration: Prosthodontic Department of Lahore Medical And Dental College, Lahore, from 1st Jan 2022, till 1st April 2022. Methodology: A total of 260 dental students were assessed for smile characteristics i.e.; smile line, smile arc, labiodental relationship and number of teeth visible during posed smile. Result: The smile line frequently observed was average smile line 52.7% followed by gummy smile line 22.3%. More male participants had average smile line whereas gummy smile line was frequently found in females. Frequently observed smile arc was consonant 63.1% followed by flat arc 22.3% and least observed arc was reverse 14.6%. Most of the participants display second premolar to second premolar teeth during posed smile 41.9%. Female display teeth up to first molar 51.5% and males up to second premolars 48.7%. Labiodental relationship frequently observed was the relation of the lips not touching the incisors 54.2%. Gender based difference with respect to smile line, smile arc, and number of displayed teeth was significant p<0.05, however labiodental relationship was insignificantly found among gender p> 0.05. Conclusion: Restorations in esthetic zone should be carried out considering smile characteristics like smile arc, smile line, labiodental relation and teeth display. Gender dimorphism should be considered as an important factor that can influence the esthetic outcome of restorations.

The oral health-related quality of life determines the quantity to which oral health disrupts the regular life and common functioning of an individual. To evaluate the oral health problems of older adults, Geriatric Oral Health Assessment Index (GOHAI) can be used. GOHAI was developed by Atchinson and Dolan3 before and after complete denture therapy”. Study Design: Cross sectional study. Setting: Department of Prosthodontics, Lahore Medical and Dental College, Lahore. Period: February 18, 2018 to August 17, 2018. Material & Methods: Patients will be selected for the study according to the criteria. Patient history and clinical examination was undertaken. Upper and lower complete dentures was made-up for 30 patients (both male and female) using standardized clinical and laboratory methods. Conventional procedures were applied to complete denture construction. Complete dentures were constructed in the similar dental laboratory within the institution by compression moulding method. Laboratory and clinical remount procedures, beside with occlusal corrections were carried out using a semi-adjustable articulator. The GOHAI questionnaire was completed on two different appointments. First questionnaire was documented before denture insertion and second questionnaire was recorded after complete denture insertion. Results: Before treatment mean GOHAI score was 20.46 ± 2.85 and after treatment mean GOHAI score was improved and was 26.32 ± 2.34. The mean GOHAI score was statistically improved p-value < 0.001. For male patients, before treatment mean GOHAI score was 21.61 ± 2.59 and after treatment mean GOHAI score was improved and was 26.31±2.14. The mean GOHAI score was statistically improved in male patient, p-value < 0.001.  For female, before treatment mean GOHAI score was 19.34 ± 2.70 and after treatment mean GOHAI score was improved and was 26.44 ± 2.49. The mean GOHAI score was statistically improved in female patients, p-value < 0.001. Conclusion: According to patient’s information enhancement in functional changes after placement of complete dentures.

Aim: To evaluate frequency of commonest location of traumatic oral ulcers after complete denture insertion and find out their association with age, gender and arch type. Study design: Cross sectional observational study Place and duration: Prosthodontic department of Islamic International Dental College, Riphah International University Islamabad, from 11th Feb.,2022 till 11th April 2022. Methodology: A sample of 150 completely edentulous patients were clinically checked for traumatic ulcer development after insertion of complete denture. Frequently involved anatomical sites were noted in both arches. Denture surfaces were assessed to find out the frequently existing denture problems responsible for ulcers. Results: Out of total 150 patients 37.3% with oral ulcers were males and 62.7 % were female. 61-70 years old age group reported with frequent ulcers 48.7%. Frequently observed oral ulcer site in maxilla was sulci 10.0% and in mandible was ridge 24.7%. Frequently observed denture problem responsible for ulcer formation was denture surface roughness 46.7%. Association with age, gender and arch type was significant; p<0.05. Conclusion: Frequent ulcers develop in mandibular arch as compared to maxilla and commonest sites of ulcer developments are the ridges and sulci. Old age and female predisposition have been seen in ulcer development. Keywords: Complete dentures, Mandibular arch, Maxillary arch, oral ulcers, traumatic ulcers, post insertion complains
