Dental caries is a very common condition, and although it has become less common, it still represents a serious public health risk. Caries symptoms range from the earliest molecular alterations in the tooth's apatite crystals to an apparent white spot lesion (WSL) or eventual cavitation. The white spot lesion looks chalky because minerals are being lost from both the surface and the underside of the enamel. A relatively simple and noninvasive caries preventive regimen in treating white spot lesions with low-level laser irradiation, either alone or with topical fluoride treatment. This treatment results in reduced enamel solubility and dissolution.
The study was reviewed and approved by the "Ethical research committee "of the Faculty of Dental Medicine for Girls; at Al-Azhar University, Cairo, Egypt. This study was conducted on 90 teeth with white spot lesions (WSLs) detected clinically on the buccal surface of teeth. The patients with WSLs were selected randomly from the operative dentistry clinic at the Faculty of Dentistry, Girl's Branch, Al-Azhar University
After examination, the teeth will be assigned into six groups of 15 teeth with white spot lesions each according to the remineralizing material used:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Remin Pro with laser application | Experimental | A photosensitizing-remineralizing agent mixture was prepared by adding pre-green dye (0.05ml) to 1 mg of the assigned remineralizing agents. The diode laser was irradiated immediately with Average power of 1 W, Exposure time of 10 s, diode 810 nm, continuous and non-contact mode, and Irradiation speed of 1mm/ sec. |
|
| Remin pro without laser application | Experimental | Used a pea-sized amount with a brush and allowed it to remain on the teeth for at least three minutes as it was recommended by the manufacturer. Instructed the patient to avoid rinsing, eating, and drinking for 30 minutes |
|
| Xpur remin with laser application | Experimental | A photosensitizing-remineralizing agent mixture was prepared by adding pre-green dye (0.05ml) to 1 mg of the assigned remineralizing agents. The diode laser was irradiated immediately with Average power of 1 W, Exposure time of 10 s, diode 810 nm, continuous and non-contact mode, and Irradiation speed of 1mm/ sec. |
|
| Xpur remin without laser application | Experimental | used a thin film of toothpaste on a micro brush and then applied it on the tooth surface for three minutes 2- Do not eat, drink or rinse for 30 minutes |

| surface area measurement | after the finalization of the remineralization protocol, another radiographic examination was undertaken. Bitewing radiographs of the lesions were taken using the same X-ray unit, film holders for bite recording and vertical angulations for standardizing the geometric projection of the X-ray beam by digital subtraction radiograph. | from base line (application of materials) to one month |

To avoid bias and for proper randomization, the study will be done per patient using tossing a coin to assign the tooth to be either treated with Nano hydroxyapatite with fluoride or Nano hydroxyapatite with xylitol or sodium fluoride.
