Comparison of two cooling procedures on linear dimensional change of heat cured acrylic maxillary complete denture base

Certain dimensional changes are known to occur in acrylic resin during or after its processing. These changes hold clinical significance because better adaptation of denture base to oral tissues is related to minimum dimensional changes after processing. This study aimed at the evaluation of linear dimensional changes of maxillary heat cured denture bases after bench cooling and rapid cooling procedure. It was a randomized controlled trial, done in Central Dental Laboratory at Armed Force Institute of Dentistry. 60 heat cured acrylic resin [PMMA], maxillary complete denture bases divided into two equal groups [A and B] of 30 each randomly using a scientific random number table were fabricated bypassing through standard heating cycle and then the flask cooled by bench cooling method and rapid cooling method for 30 each. Linear dimensional changes from point A to B, A to C and B to C were noted. The study sample were considered to be significant with the p-value 0.003, 0.001 and 0.001 respectively. Bench cooling is a preferable technique to improve the mucosal adaptation of the denture base and less dimensional changes

Xeroderma pigmentosum with melanoma of face and its prosthetic management

Xeroderma pigmentosum is a rare genetic disorder, characterized by cutaneous, ocular and neurological symptoms. Squamous cell carcinoma and melanoma are also its secondary characters. This case report is about maxillofacial prosthetic management of a 10 years old child presented with xeroderma pigmentosum. The nose of the patient was excised surgically due to melanoma. This case report elaborates the role of prosthodontist and the whole procedure of constructing the nasal prosthesis via conventional technique by using the patient's sibling nasal form as template. Regular follow up revealed marked improvement in esthetics, function and ultimately patient's quality of life

Evaluation of oral function after removable partial denture therapy

This study aimed to evaluate the oral function after removable partial denture therapy from patients perspective. It was a descriptive case series. One hundred and ten partially dentate subjects were studied in the Department of Prosthodontics, de, Montmorency college of dentistry, Lahore. All the subjects were given oral health impact profile -14 questionnaire before and one month after provision of removable partial denture. Before and after treatment responses were recorded on 5 point Lickert scale. The post treatment scores were compared with pretreatment baseline scores and improvement in oral functional problems were assessed. 96% of study subjects had problems in pronouncing words, which persisted in 56% of the subjects after using removable partial denture. 94% of the study group had taste problems before removable partial denture treatment, which improved in 50% of study population after therapy. This suggested that removable partial dentures had a positive impact on oral function in almost half of the population. Lack of improvement in remaining group can be attributed to lack of education and awareness which was responsible for negative attitude of these patients towards removable partial dentures

Attitude of dental students towards elderly

The aim of this study was to assess the attitude of dental students towards elderly patients. This increased the awareness of the need of the geriatric dental education within the undergraduate dental curriculum, which is the pressing need for today. The study was carried out at the de,Montmorency College of Dentistry, Lahore-Pakistan. It was a descriptive cross sectional study. Study sample comprised of sixty final year students. Attitude of students towards elderly was measured using a self administered questionnaire consisting of ROZENCRANZ AND MCNEVIN AGING SEMENTIC DIFERENTIAL SCALE. Students attitude was found to be very positive towards elderly patients as they showed a strong desire to work with elderly patients. This showed that the future geriatric dentistry is not towards a decline in Pakistan as compared to negative attitudes of students in the developed countries
