Article Synopsis
- This study evaluated the impact of serum vitamin D levels on external apical root resorption (EARR) in maxillary anterior teeth among patients undergoing fixed orthodontic treatment.
- Patients aged 12 to 30 underwent the same orthodontic procedure, with EARR assessed through panoramic radiographs and serum vitamin D levels measured after treatment.
- Results showed significant root length reduction with 75% of patients experiencing EARR, but there was no significant link between EARR and vitamin D levels, indicating a need for strategies to reduce root resorption.
In this study, high-frequency ultrasound wave (1.8 MHz) at low intensity was applied to improve activated sludge settleability at high MLSS concentration. The effect of irradiation intensity, sonication mode, MLSS concentration and sample volume on the physical characteristics of sludge in a pilot scale settling column were investigated for optimizing the conditions.

In this study, high-frequency ultrasound wave (1.8 MHz) was applied to enhance the CAS process performance using high Mixed Liquor Suspended Solid (MLSS) concentration.
