What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Probiotic (L. brevis CD2 lozenges)Other

    Probiotic :composed of powerful strain of s.salivarius that preserve innate immune system of the main entry point of the body by taken on a regular basis and establish colonization of the throat and mouth which provide clinical care and support of nose, ear, mouth and throat health and provide fresh breath.

  • Zinc chlorhexidine mouth washBehavioural

    Zinc chlorhexidine mouth wash (Zn/CHX) composed of CHX concentrated 0.025% with Zinc acetate 0.3 %, the low concentration of CHX to maintain optimal efficacy with lower incidence of side effects. Zn /CHX was chosen as the active control due to the fact the mixture of Zn salts with low concentration of CHX have shown superior and sustained intra-oral efficacy in managing intra oral halitosis in randomized clinical tria

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plaque accumulation

    plaque build up on bracket surfaces was evaluated by using modified bonded bracket index ( mbb index), Each tooth was divided into four areas (incisal, distal, mesial, gingival). Plaque accumulation was classified into the following assessment grades: grade 0-no plaque, grade 1-plaque covered ≤ 1/3 of the tooth surface, grade 2-plaque covered ≤ 2/3 of the tooth surface, grade 3-plaque covered > 2/3 of the tooth surface. Plaque index (%)= Total of plaque values/ Number of surfaces/ Highest graduation score

    × 100.

    Measured: 4 month

  2. Halitosis

    subjective assessment of halitosis determined by using organoleptic score (OLS) 0 No perceivable odor

    1. Weakly perceivable odor
    2. Perceivable odor
    3. Moderate odor
    4. Strong odor
    5. Extremely strong odor

    Measured: 4 month
