Dental impressions can act as vehicle for various types of microorganisms E.g. Hepatitis B, C, HIV, Mycobacterium, Herpes simplex, Ebola, MERS-CoV etc. The most effective way to prevent their spread through dental impression is to make the impression sterile just after coming out of mouth. Various methods of impression disinfection have been described in literature having their own advantages, disadvantages and effects on impression material. In order to enhance the knowledge and improve the behavior of dental health care workers about impression disinfection, a structured literature review of the current disinfection techniques has been carried out. It will also provide knowledge about mechanism of action, concentration of usage along with commercial preparations available of different disinfectants. HOW TO CITE: Mushtaq MA, Khan MWU. An overview of dental impression disinfection techniquesa literature review.

The aim of this study was to determine the level of awareness about knowledge and practices of complete denture hygiene in a tertiary care dental hospital of Lahore.

OBJECTIVE:Co-morbidity is a medical condition accompanied to the primary condition for which patient is seeking medical or dental care. To determine the frequency of medical co-morbid conditions in dental patients. METHODOLOGY: After obtaining informed consent, a comprehensive predesigned history form was implemented to record patient's medical conditions. Different variables recorded for each participant were age, gender and history of medical co-morbid conditions including diabetes mellitus, hypertension, ischemic heart diseases, renal disorders, typhoid, thyroid disorder, degenerative joint disorder, asthma, hepatitis B, hepatitis C, hepatitis A and E, HIV and tuberculosis. RESULTS: In this study, hypertension accounted for 9.5% in total number of patients followed by degenerative joint disorders and hepatitis C with the same frequency of 5.2%. Diabetes mellitus and hepatitis B accounted for 3.4% of the patients CONCLUSION: This study concludes that presentation of medically compromised patients in dentistry is inevitable.

Background:Hypodontia is the developmental absence of one or more teeth from the dentition whereas acquired missing teeth are those lost due to carries, periodontal problem or dental trauma. Patients with congenitally missing teeth suffer aesthetic, functional and psychological morbidity to various degree through childhood, adolescence and adulthood. Greater understanding of the impact of hypodontia on patient's quality of life is very important. Oral health related quality of life (OHRQoL) is considered as an outcome measure to evaluate the consequences of edentulism and the available treatment options. Material and Methods:A cross-sectional comparative survey was carried out in the department of Prosthodontics, de'Montmorency College of Dentistry/Punjab Dental Hospital Lahore from 02/03/2010 to 01/09/2010. Total 80 partially dentate patients were studied which included 40 hypodontia patients and 40 patients with acquired missing teeth. All patients were given OHIP-14 questionnaire and responses were recorded on 5-point Likert scale. The mean scores of the two groups were calculated and compared using chi square test. Results:The total OHIP scores in hypodontia patients was more compared to that in patients with acquired missing teeth and difference was significant in the patient group with 4-5 missing teeth. Conclusion:As the missing teeth number increased, it was found that the OHRQoL in hypodontia patients was more impaired compared to the OHRQoL in patients with acquired missing teeth.

Denture Induced Hyperplasia or Epulis fissuratum is a tumor-like reactive lesion of oral mucosa because of chronic irritation caused by ill-fitting dentures. It is mostly presented in female denture wearers with a predilection to maxilla. These lesions can be of varying sizes ranging from few centimeters to extensive involving the whole arch. These can be managed conservatively or by complete surgical excision depending upon the size and complexity of the lesion. In this case report, an enormous denture induced hyper-plastic lesion in an old male denture wearer is presented. The lesion was located in the maxillary left labial vestibule. This lesion was excised surgically, followed up for change of tissue conditioner up to one month. After completion of healing of wound, new complete denture was fabricated.
