Final answer:
The purpose of resin infiltration in dentistry includes improving aesthetics, preventing decay, and being non-destructive and reversible. It conserves the original tooth structure and may also reduce sensitivity.
Step-by-step explanation:
The purpose of resin infiltration is multi-faceted, but when considering the context provided regarding restorations, the most relevant objectives appear to be to improve aesthetics and to prevent decay. Resin infiltration is a minimally invasive procedure whereby resin is introduced into demineralized enamel of teeth to arrest the progression of carious lesions and improve the appearance of the tooth. This is particularly true for early caries lesions, which can be treated effectively with resin infiltration. A significant aspect of this procedure is its ability to be non-destructive and reversible.
Restorations should always aim to conserve the original structure of the tooth, hence being non-destructive. The reversibility aspect is also crucial as it accounts for potential future advances in dental treatments that might offer even less invasive options. It is notable that resin infiltration can also reduce sensitivity by blocking the tubules that lead to the nerves within the tooth, thus protecting against stimuli that cause pain. While the procedure does provide some strength, the primary goals are related to preservation, aesthetics, and patient comfort.
