NCT04871763

Brief Summary

The aim of this study is to investigate the bacterial loads present on essix retainers in patients' contention therapy. Patients are randomly divided into three groups, depending on the product used for the cleansing of the retainers: Geldis, Polident tablets and water. Microbiological samples were taken from the retainers at the baseline, after 1 and after 2 months, together with Bleeding Index, Plaque Index, BEWE Index and Schiff Air Sensitivity test.

Outcome Measures

Primary Outcomes (5)

  • Change in PCR% - Plaque Control Record (percentage)

    % assessment of the amount of plaque on dental surfaces; it is detected on 4 surfaces: distal, mesial, vestibular, lingual / palatal. The number of sites with plaque is divided by the total number of sites available in the mouth and multiplied by 100. Results indicate the index as a percentage.

    Study begin, 1 and 2 months

  • Change in BOP - Bleeding on Probing (percentage)

    Site-specific assessment of the presence or absence of gum bleeding after the insertion of the periodontal probe for the detection of PPD, detected on 4 sites (mesial, distal, vestibular, palatal/lingual). Percentage of sites with bleeding on probing determines the BOP%.

    Study begin, 1 and 2 months

  • Change in Schiff Air Index - Dental sensitivity test

    Scoring criteria: * 0: the subject did not respond to air blasting; * 1: the subject responded to air blasting; * 2: the subject responded to air blasting and requested discontinuation; * 3: the subject responded to air blasting, requested discontinuation and considered the stimulus to be painful.

    Study begin, 1 and 2 months

  • Change of the BEWE Index - Basic Erosive Wear Examination (Barlet et al., 2008)

    Scoring criteria: 0: no erosive tooth wear; 1. initial loss of surface texture; 2. distinct defect, hard tissue loss \< 50% of the surface area; 3. hard tissue loss ≥ 50% of the surface area.

    Study begin, 1 and 2 months

  • Change in microbiological loads of clear aligners

    Microbiological assessment of the following loads: * Porphyromonas gingivalis * Tannarella forsythensis * Treponema denticola * Peptostreptococcus micros * Total bacterial load

    Study begin, 1 and 2 months
