Summary
This study on resin composite restorations found that preoperative hypersensitivity was linked to radiograph visibility, not caries activity. Unexpectedly, many teeth had hypersensitivity before treatment or developed it post-treatment.
Area of Science:
- Dental Restorations
- Caries Management
- Clinical Dentistry
Background:
- Posterior permanent teeth restorations are common.
- Resin-based composites are widely used.
- Postoperative hypersensitivity remains a concern.
Purpose of the Study:
- To investigate factors associated with hypersensitivity in resin composite restorations.
- To analyze correlations between preoperative hypersensitivity and clinical/radiographic variables.
- To assess the incidence of post-treatment hypersensitivity.
Main Methods:
- 565 posterior teeth with dentin caries were restored using resin composite by 38 dentists.
- Hypersensitivity was measured preoperatively and at 1, 4, and 13 weeks post-treatment using a visual analog scale.
- Statistical analyses explored correlations between hypersensitivity and variables like caries activity, cavity extent, and material application.
Main Results:
- Only 36% of lesions were classified as caries-active.
- 31% of teeth exhibited significant preoperative hypersensitivity.
- 16% of teeth without preoperative hypersensitivity developed it by 1 week post-treatment.
Conclusions:
- Preoperative hypersensitivity correlated with radiographic lesion visibility but not with dentin caries activity, preparation depth, or volume.
- Further analysis of 13-week data is needed to draw definitive conclusions on other relationships.
