Effect of flowable composites on tooth sensitivity after Class I fillings
Official title: Evaluation of Dental Restorations
Run by Recep Tayyip Erdogan University · NCT07343050 · Data updated 2026-11-12
This research will test whether using conventional versus bulk‑fill flowable composite materials causes different amounts of tooth sensitivity after Class I fillings in adults with dentin caries.

Is this trial a fit for you?
✓Likely a good fit
Adults with dentin caries who are in good general health, not pregnant or breastfeeding, not undergoing orthodontic treatment, and without advanced periodontitis or the specified systemic diseases are ideal candidates.
✕Probably not a fit
Patients with advanced periodontitis, those who are pregnant or breastfeeding, undergoing orthodontic treatment, using dental appliances, or requiring direct pulp capping are unlikely to benefit from participation.

What this trial studies
This is an observational, single‑center comparison of conventional flowable and bulk‑fill flowable composite materials used in Class I restorations, with long‑term follow‑up for postoperative sensitivity. Participants receive routine Class I restorations and are monitored over time for levels of tooth sensitivity and clinical success. Eligible patients are adults in good general health without listed systemic diseases and without advanced periodontitis, pregnancy, breastfeeding, orthodontic appliances, or direct pulp capping. The working hypothesis is that the type of composite material will not meaningfully change clinical success or long‑term sensitivity outcomes.
Why it matters
Potential benefit: If successful, results could help dentists choose filling materials that reduce postoperative tooth sensitivity for patients with dentin caries.
How similar studies have gone: Previous clinical comparisons of bulk‑fill and conventional flowable composites have shown mixed results, so this study adds longer‑term observational data rather than introducing a wholly novel approach.
