Design outcomes

Primary

Measure	Time frame
Time required to correct Class I dental irregularities. Timepoint: Start of study: Before starting treatment, to record the initial condition of the teeth and existing irregularities.Duration of treatment: Regularly during the treatment period, usually at each patient visit to assess the progress of treatment.End of treatment: After the treatment period is completed and the treatment goal (correction of dental irregularities) is achieved. Method of measurement: Conducting a comprehensive clinical examination to assess the condition of the teeth, jaw, and soft tissues of the mouth. Recording the type and severity of Class I dental irregularities based on standard criteria. Digital scanning and dental models: Preparing 3D dental models through scanning or traditional impressions.	—

Secondary

Measure	Time frame
Gum health. Timepoint: At the beginning of the study, after each treatment session, and at the end of treatment. Method of measurement: Gingival Bleeding Index (GI): Evaluation of gingival bleeding after each LED treatment session. Plaque Index (PI): Evaluation of the amount of plaque on the surface of the teeth after each LED treatment session. Gingival Health Index (GI-modified): Evaluation of the overall health of the gums.	—
