Damascus University50 enrolled

Overview

Fifty patients needing non-extraction-based metallic orthodontic treatment will be divided randomly into the probiotic group and the control group. In each group, they will brush their teeth regularly while receiving orthodontic treatment. Only the probiotic group will take probiotic tablets for six months. Clinical parameters will be assessed before and during orthodontic treatment and after 3 and 6 months during treatment.

Each subject will be examined completely to ensure eligibility before enrolling in the study. The operator will then inform them about the study's aim and ask them to provide written informed consent. Patients will receive professional scaling, polishing, and oral hygiene instruction before the research starts. Regarding the probiotic, (PRODENTIS) is commercially available in Sweden and the USA. Probiotics prepared by Bio-Gaia AB (Stockholm, Sweden). Each probiotic tablet contains two strains of probiotic lactic acid bacteria of human origin: L. reuteri DSM 17938 and L. reuteri ATCC (PTA 5289), each at a minimum of 1 × 108 CFU per lozenge. The tablets should be stored at a temperature below 25 ◦C. Dosage instructions will be prescribed per the manufacturer's recommendations at a preventive dosage of 1 lozenge/day (after dinner and teeth brushing). Regarding the clinical parameters, the Plaque index (Pl), the gingival index (GI), the Papillary Bleeding Index (PBI), 1977, and probing depth (PD) will be evaluated.

Outcomes

Primary Outcomes

The change in the plaque index

Assessment will be achieved using a gingival probe, according to Silness and Loe (1964). The criteria for plaque index are as follows: 0\. No plaque 1. A film of plaque adheres to the free gingival margin and adjacent area of the tooth. The plaque may be seen in situ only after the application of the disclosing solution or by using a probe on the tooth surface. 2. Moderate accumulation of soft deposits within the gingival pocket, or the tooth and the gingival margin, which can be seen with the naked eye. 3. An abundance of soft matter within the gingival pocket and/or the tooth and gingival margin.

Time frame: Time Frame: T0: immediately before applying the fixed appliance; T1: at three months; T2: at six months

The change in the gingival index

Assessment will be achieved using a gingival probe, according to Silness and Loe (1964). The criteria for the gingival index are as follows: 0\. Normal gingiva. 1. Mild inflammation: a slight change in color, slight edema, no bleeding on probing. 2. Moderate inflammation: moderate glazing, redness, edema, hypertrophy, bleeding on probing. 3. Severe inflammation: marked redness and hypertrophic ulceration, tendency to spontaneous bleeding.

Time frame: Time Frame: T0: immediately before applying the fixed appliance; T1: at three months; T2: at six months

The change in papillary bleeding index

Assessment will be achieved using a gingival probe, according to Muhlemann (1977). 0\. No bleeding. 1. A single discreet bleeding point appears. 2. Several isolated bleeding points or a single fine line of blood appear. 3. The interdental triangle fills with blood shortly after probing. 4. Profuse bleeding occurs after probing; blood flows immediately into the marginal sulcus.

Time frame: Time Frame: T0: immediately before applying the fixed appliance; T1: at three months; T2: at six months

The change in the probing depth

Assessment will be achieved using a gingival probe, according to Bowers (1964). It will be measured clinically as the distance from the free gingival margin to the gingival sulcus. The reading of PD ≤3 mm was considered normal, while any reading \>3 mm was considered a gingival pocket
