halitosis

1. Plaque accumulation

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.

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.
