[Gingival deflection and regeneration after electrotomy]

Area of Science:

• Dental materials science
• Minimally invasive dentistry
• Oral surgery techniques

Context:

• Accurate visualization of cavity preparation margins is critical for successful hydrocolloid impressions in restorative dentistry.
• Conventional mechanical gingival displacement using cotton threads can be insufficient, especially in complex or multiple dental preparations.
• Challenges include bleeding and fluid seepage from the gingival sulcus, hindering impression material adaptation.

Purpose:

• To evaluate the efficacy of electrosurgery as an alternative method for gingival tissue management in hydrocolloid impression procedures.
• To compare the effectiveness of electrosurgery against mechanical displacement with cotton threads for margin visibility.

Summary:

• Electrosurgery, when applied judiciously, provides excellent control over gingival bleeding and sulcular seepage.
• This technique enhances the accessibility of cavity preparation margins for accurate hydrocolloid material capture.
• Results indicate electrosurgery surpasses traditional methods in ensuring clear margin visualization for dental impressions.

Impact:

• Improved diagnostic accuracy and treatment planning through clearer impression details.
• Enhanced predictability of restorative dental procedures by ensuring precise marginal fit.
• Potential for increased efficiency in dental impression taking, particularly in challenging clinical scenarios.
