Abstract
Dental inlay wax is a mixture of several waxes, usually containing paraffin wax, ceresin wax, beeswax and other natural and synthetic waxes. It is used to prepare patterns for gold or other metallic materials in the fabrication of inlays, crowns and bridges. Inlay wax is used for the same purpose as casting wax in the formation of pattern mostly for metallic casting in Dental technology. This study aimed at producing dental inlay wax using locally sourced materials in Enugu, Nigeria. The research was carried out between July to September, 2018 in Enugu, Nigeria. The study adopted a three phased experimental approach using the same procedures but different weight compositions. Structured, pretested Product Evaluation Data Sheet was used to evaluate the product by selected Practicing Dental Technologists in Enugu State, Nigeria. The resultant wax from experiment III with the following composition: 60g Paraffin wax, 5g Beeswax, 25g Carnauba wax, 10g Ceresin wax and (35g) of green ketchup colorant gave the best result. Its properties are comparable to the conventional Dental Inlay wax. There was significant agreement among the respondents in the smoothness of the product (40%); excellent dimensional stability and product effectiveness (40%); flow and burnout of the product (35%), and color stability of the product (45%). These findings suggests that dental inlay waxes can be produced locally in Enugu, Nigeria. Therefore, more attention needs to be paid in the production process, which will facilitate easy practice of Dental Technology, and also conserve huge foreign exchange being spent in the importation of inlay wax in Nigeria.
Highlights
In Dental Technology practice, only few procedures can be completed without the use of wax in one of its many forms [1]
The study was conducted at the Federal College of Dental Technology and Therapy, Enugu, Nigeria
The results of this study indicate that locally produced inlay wax is smooth enough as attested to by the Dental Technologists who evaluated the product
Summary
In Dental Technology practice, only few procedures can be completed without the use of wax in one of its many forms [1]. It has been difficult to define wax. William (2012) defined “wax” in chemical term, which was derived from the Anglo-Saxon word “weax” for beeswax practically as a substance similar in composition and physical properties to beeswax [2]. Manappallil (2003) defined wax as a variety of products of thermoplastic nature for all those uses where there is a necessity for a material that is soft and easy to model that becomes rigid and stable with cooling [3]. Waxes exist in form of natural and synthetic substances. The natural ones can be divided into renewable and nonrenewable. The renewable waxes are re-growing and can be
