Acrylic resin is commonly used to fabricate removable prostheses due to its adequate physical, mechanical properties and cost effectiveness. There has been continuous development of the materials to improve their properties and to widen its application in different clinical setting. To study the history development of the acrylic resin and elaborate on the properties of different types and the processing methods of acrylic resins used to fabricate denture base which are commercially available in the market. This would help the dental clinician in choosing the best material of choice. The authors have summarized the history, development and classification of different types of acrylic resins used in fabricating denture and processing methods based on all the published research available on this topic using published materials available in the Dental Library, University of Malaya and the database (Science Direct, PubMed). Every type of acrylic denture base material has its pros and cons. Therefore, careful selection of material and the processing method is crucial to ensure the best outcome for prosthodontic treatment. Hence, upholding the patients’ best interest and improving their quality of life.

When fixed partial dentures (FPDs) are being suggested to patients, the frequent inquiry by patients is the anticipated longevity and length of service. Previous reports have provided limited information on the accurate measurements of good clinical outcome and the length of good years in service. This confuses the clinicians as well as the patients in determining the treatment of choice. In the present article, the indicator of ‘success’ and ‘survival’ will be discussed in determining the longevity of various FPDs such as conventional, resin bonded and implant retained. After reviewing the articles, it is good if the indicator of ‘success’ can be used as an indicator of longevity and good clinical outcome. Besides that, studies with at least 10 years of observation are probably of higher evidence for longevity of restorations.

The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e. cerebral angiography in the workup of patients with hemiplegia. Other cases are of historical social interest, being conditions seen during earlier stages of Singapore's development, i.e. bound feet. The archives form a unique portal into the development of local radiology as well as the national development of Singapore. A selection from the archives is published in 2020 in commemoration of the 20th anniversary of the formation of SingHealth, the 55th National Day of Singapore, and the 125th anniversary of the International Day of Radiology. This pictorial essay comprises cardiovascular, respiratory and neurological cases from the archives.
