The article presents contemporary methods of operative field isolation used during the restorative treatment of cervical lesions, with particular emphasis on defects of non-carious origin. Key stages of the clinical procedure are discussed, including assessment of the patient’s oral hygiene status and appropriate preparation of the tissues prior to treatment. Effective isolation–protecting the operative field from saliva, gingival fluid, and blood–is a fundamental prerequisite for successful restorative therapy and requires the selection of appropriate techniques and instruments. The paper analyzes various isolation methods, including retraction cords (mechanical and chemical), metal matrices, celluloid strips, and rubber dam. Each technique differs in its properties, influencing the clinician’s comfort, the ability to achieve adequate visibility and dryness of the operative field, and the long-term durability of the restorations. Attention is drawn to the fact that the proper choice of isolation method should be tailored to the characteristics of the lesion and the patient’s individual anatomical conditions, as this directly affects the aesthetics and functionality of the final restoration. The article highlights the importance of thorough preparation for restorative treatment, which is particularly significant in the case of cervical lesions due to their specific location and the challenges associated with achieving optimal working conditions.
