Entrapment of Citrus limon var. pompia Essential Oil or Pure Citral in Liposomes Tailored as Mouthwash for the Treatment of Oral Cavity Diseases
2020
This work aimed at developing a mouthwash based on liposomes loading Citrus limon var. pompia essential oil or citral to treat oropharyngeal diseases. Vesicles were prepared by dispersing phosphatidylcholine and pompia essential oil or citral at increasing amounts (12, 25 and 50 mg/mL) in water. Transparent vesicle dispersions were obtained by direct sonication avoiding the use of organic solvents. Cryogenic transmission electron microscopy (cryo-TEM) confirmed the formation of unilamellar, spherical and regularly shaped vesicles. Essential oil and citral loaded liposomes were small in size (~110 and ~100 nm, respectively) and negatively charged. Liposomes, especially those loading citral, …
Effect of orthodontic treatment on saliva, plaque and the levels of Streptococcus mutans and Lactobacillus
2009
Objectives: The aim of this study was to identify changes in the oral environment with clinical, salivary and bacterial risk markers after placement of fixed orthodontic appliances on permanent dentition. Material and Methods: With ethical approval, we used different techniques to analyzed clinical, salivary and bacterial risk markers in 34 patients (mean age, 16.7 ± 5.2 years), 14 males and 20 females; before starting orthodontic treatment and 1 month after. Clinical risk markers (decayed, missing, and filled surfaces [DMFS], O?Leary´s plaque index, and plaque pH); salivary markers (unstimulated and stimulated saliva flow rate, buffer capacity, pH, and occult blood in saliva) and bacterial…
Discriminant ability for caries risk of modified colorimetric tests.
2010
Objetive: The aim of this study was to evaluate the relationship between the caries risk in children over a two-year period and their baseline caries status, salivary levels of mutans streptococci and lactobacilli, and results of the Alban test and modifications thereof using different substrates. Study design: Ninety-five children aged 6-7 were examined in Granada (southern Spain) for dental caries at baseline and every six months. Stimulated saliva was sampled and inoculated in 7 colorimetric tests based on Snyder's medium with different sugars and polyalcohols. A mutans streptococci and lactobacilli count was performed (Dentocult SM strip® and Dentocult LB®). Caries risk proportions were…
