Effect of a calcium phosphate-containing desensitizing agent on postoperative sensitivity: A split-mouth, randomized...

Area of Science:

• Dentistry
• Dental Materials Science
• Clinical Research

Background:

• Postoperative sensitivity (POS) is a common concern after dental restorations.
• Deep and extremely deep caries lesions present unique challenges for managing sensitivity.

Purpose of the Study:

• To evaluate the effectiveness of Teethmate Desensitizer (TD) in reducing postoperative sensitivity (POS).
• To assess the influence of caries type, subject age, and preoperative hypersensitivity on POS after composite restorations in deep lesions.

Main Methods:

• A randomized controlled study involving 50 subjects with deep or extremely deep caries.
• Teethmate Desensitizer (TD) was applied to one tooth per participant; all teeth received composite restorations.
• Postoperative sensitivity was evaluated using numerical rating scale (NRS) and visual analogue scale (VAS) at 1 and 6 weeks.

Main Results:

• Teethmate Desensitizer (TD) showed a small effect size with no statistically significant reduction in POS for NRS and VAS.
• No significant differences in POS were found concerning subject age, caries type, or preoperative sensitivity.
• The study observed no statistically significant impact of TD on postoperative sensitivity.

Conclusions:

• Teethmate Desensitizer (TD) did not demonstrate a significant effect on reducing postoperative sensitivity in deep or extremely deep cavities.
• Caries type, patient age, and preoperative sensitivity levels did not influence the effectiveness of TD.
• Further research may be needed to explore alternative desensitizing agents or management strategies.
