Study type | Interventional |
Patients at the Orthodontic Department of the University of Damascus Dental School will be examined and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, and radiographic images) will be studied to ensure that the selection criteria are accurately matched. This study aims to compare two groups of patients with moderate crowding of the lower anterior teeth. Experimental group: the patients in this group will be treated with periodontally accelerated osteogenic orthodontics Control group: the patients in this group will be treated using fixed appliances without any acceleration method.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Little's Index of Irregularity | The irregularity of the lower incisors is calculated by measuring the amount of deviations of the anatomic contact points between the six anterior teeth in the horizontal direction in mm, since the sum of these measurements represents the value of the index (Little, 1975).
The ordinary orthodontic treatment aims to keep this Index less than 1 mm at the end of treatment. |
T0: one day before the beginning of treatment; T1: after 1 month; T2: after 2 months; T3: after 4 months; T4: after 5 months; T5: at the end of the alignment stage which is expected within 5 - 6 months | |
Primary | Change in the inter-canine width | The distance between the cusp tips of the lower canines. This variable will be measured on plaster models. | T0: One day before the beginning of treatment; T1: at the end of the alignment stage | |
Primary | Change in the inter-2nd premolar width | The distance between the central fossae of the lower second premolars. This variable will be measured on plaster models. | T0: One day before the beginning of treatment; T1: at the end of the alignment stage | |
Secondary | Change in the Gingival index | Measured by degrees at each tooth: (0) Normal gingival; (1) mild inflammation; (2) Moderate inflammation; (3) severe inflammation | T0: One day before the beginning of treatment; T1: at the end of the alignment stage | |
Secondary | Change in the Plaque index | Measured by degrees at each tooth: (0) No plaque; (1) thin plaque layer; (2) moderate plaque layer; (3) severe plaque along the gingival margin | T0: One day before the beginning of treatment; T1: at the end of the alignment stage | |
Secondary | Change in the Papillary Bleeding Index | Measured by the severity of any bleeding: (0) No bleeding; (1) a single discreet bleeding point; (2) several isolated bleeding points; (3) the interdental triangle fills with blood shortly after probing; (4) profuse bleeding occurs after probing. | T0: One day before the beginning of treatment; T1: at the end of the alignment stage |
