Acid Etching's Effect on Hypomineralized Teeth's Bond Strength and Enamel Surface Structure.

The current study evaluated the bracket bond strength of hypomineralized teeth with and without acid etching. Twenty premolar teeth extracted for orthodontic purposes were used in this study. Hypomineralization was induced in all experimental teeth using a cariogenic solution.

Comparative evaluation of the remineralizing potential of Salvadora persica and probiotic yogurt on incipient enamel lesions: An ex-vivo study.

Background: Salvadora persica (miswak) is known to exert antibacterial, antifungal, antioxidant, and anticariogenic effects by elevating the pH of plaque after the consumption of sucrose.

Objectives: The study aimed to compare the effectiveness of S. persica and probiotic yogurt in the remineralization of tooth enamel on artificially produced enamel lesions.

The effectiveness of in the preservation of periodontium after radiation therapy: An experimental animal study.

Background: Radiation therapy produces reactive oxygen species, which have been linked to various degenerative conditions in periodontal attachment. This study aimed to assess the beneficial effects of aqueous leaf extract on the periodontium of albino rats exposed to fractionated gamma radiation.

Materials And Methods: This experimental study involved 24 adult male albino rats divided into three groups: Group M received leaf extract (300 mg/kg) intraperitoneally for 14 days; Group R received 20 Gy fractionated gamma irradiation; and Group MR received the same regimen as Group M and then fractionated gamma irradiation dose as Group R.

Possible radioprotection of submandibular glands in gamma-irradiated rats using kaempferol: a histopathological and immunohistochemical study.

Background And Purpose: Salivary gland damage remains a problem despite advances in radiotherapy schedules for head and neck cancer. Kaempferol, a natural flavonoid, found in several fruits and vegetables, is a good antioxidant. This study was designed to evaluate the possible protective effects of kaempferol on submandibular glands (SMGs) of rats exposed to fractionated gamma irradiation.

Modeling the artificial lake-surface area change in arid agro-ecosystem: A case study in the newly reclaimed area, Egypt.

Land reclamation is critically required to overcome the environmental and anthropogenic challenges in arid lands. The Western Nile Delta region, Egypt, is experiencing rapid reclamation processes for agriculture expansion. West Nubaria (781.

Use of portable X-ray fluorescence spectrometry for environmental quality assessment of peri-urban agriculture.

Urban expansion into traditional agricultural lands has augmented the potential for heavy metal contamination of soils. This study examined the utility of field portable X-ray fluorescence (PXRF) spectrometry for evaluating the environmental quality of sugarcane fields near two industrial complexes in Louisiana, USA. Results indicated that PXRF provided quality results of heavy metal levels comparable to traditional laboratory analysis.
