NCT04865796

Brief Summary

The aim of this study is to investigate epidemiology and treatment possibilities of black stains, with the assessment of a possible correlation with patients' dietary habits. Patients will be randomly divided into three groups. For each group, clinical evaluation will be performed at the study begin, after 2 and after 6 months. At the study begin, evaluation of black stains with Gasparetto's classification will be assessed; then professional oral hygiene with ultrasonic scaler will be performed, plus glycine and polish; then, products for home oral care will be given to patients, depending on the groups. The clinical situation will be re-evaluated after 2 and after 6 months. Home oral care will be performed with different products, containing lactoferrin (group 1) and probiotics (group 2). The control group (Group 3) will use normal products.

Outcome Measures

Primary Outcomes (1)

  • Change in the extension of black stains (Gasparetto et al., 2003)

    Scoring criteria: * 1: presence of pigmented dots or thin lines with incomplete coalescence parallel to gingival margin; * 2: continuous pigmented lines, which can be easily observed and limited to half of the cervical third of the tooth surface; * 3: presence of pigmented stains extending beyond half of the cervical third of the tooth surface

    Study begin, 2 and 6 months.

Secondary Outcomes (3)

  • Change in DMFT (Decayed Missing Filled Teeth) score

    Study begin, 2 and 6 months.

  • Change in DMFS (Decayed Missing Filled Surfaces) score

    Study begin, 2 and 6 months.

  • Dietary habits

    Study begin, 2 and 6 months.
