Study Overview
=================
Brief Summary
-----------------
This study will be conducted to evaluate clinical and radiographic success of Photodynamic Therapy for root canal treatment of primary molars in comparison to the standard root canal treatment.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of clinical success of photodynamic therapy | The following criteria will be used for the determination of treatment success or failure: Repair (= success) Clinically: absence of signs and symptoms. Lack of repair (= failure) Clinically: signs and symptoms indicative of acute apical periodontitis. | 14 months | 
| Evaluation of radiographic success of photodynamic therapy | The following criteria will be used for the determination of treatment success or failure: Complete repair (= success) Radiographically: absence of pathological root resorption, normal width of periodontal ligament space, absence of lesion development in periapical regions in cases of absence of lesion in the initial diagnostic radiograph and complete regression of lesion in cases of presence of lesion in the initial diagnostic radiograph. Incomplete repair (= success) Radiographically: absence of pathological root resorption and reduction lesion size in the periapical region. Lack of repair (= failure) Radiographically: presence of pathological root resorption, lesion in furcation/periapical region unchanged in size during follow-up period, increase in lesion size or the development of a new lesion. | 14 months |
