BACKGROUND: Corrosion of dental instruments reduces their functionality and salvage value, prompting the need for timely managerial decisions regarding replacement or restoration. In the absence of an objective framework for assessing the clinical and economic viability of these options, the risk of inefficient spending increases.
AIM: To provide a clinical and economic rationale for restoring corroded dental instruments rather than disposing of them.
METHODS: A mathematical model was developed based on a formula incorporating the costs of restoration, disposal, depreciation, and the extended service life of instruments following restoration. A Python-based software algorithm was implemented to visualize outcomes using a clinical-economic feasibility matrix. Scenario analyses were conducted across varying cost parameters and service life extensions.
RESULTS: The developed software determines the economic feasibility of instrument restoration under specific conditions. For example, if disposal costs are 10%, restoration costs are 80%, and depreciation is estimated at 15% of the instrument’s original value, restoration is deemed economically viable if the post-restoration service life increases by at least 76% of the standard operational life. The algorithm also identifies threshold cost values favoring restoration over replacement.
CONCLUSION: An innovative decision-making model was developed, incorporating both mathematical and software algorithms to assess the feasibility of restoring dental instruments. Findings indicate that, when a significant extension in service life is achievable, restoration is more cost-effective than purchasing new instruments. The Python programming environment provides a universal platform for informed decision-making in dental practice.
