A systematic review on modulation of oral biofilm and immune response associated to mucosa with probiotic bacteria as a potential approach in the prevention of dental caries
(BP Internacional, 2021) Rodríguez Coyago, María de Lourdes; Buestan Zambrano, Juan Fernando; Yamunaque Vire, Jessica Micaela; Pinos Gavilanes, Maria Paz; Osorio Ayala, Lesly Damaris
Background: A variety of approaches have been developed for the control of dental caries, a pathology with high incidence and prevalence worldwide. The use of probiotic strains for the modulation of dental biofilm in the prevention of caries has been studied, but the available evidence shows varied methodologies; and the strains tested differ from one study to another. Objective: To analyze the efficacy of using probiotic strains to prevent caries through the modulation of biofilm and immune response associated to oral mucosa. Methods: A search was made in the scientific bases PubMed, Cochrane and Science Direct, prioritizing randomized double and triple-blind clinical trials from 2010 to 2020, including a total of 20 studies to be analyzed. The selection criteria were consistent with the Preferred Reporting Items for Systematic Reviews protocol. Results: Within the studies, different types of probiotic bacteria were analyzed, dominating Lactobacillus paracasei. While most clinical trials show a favorable response in terms of a significant reduction of Streptococcus mutans in the oral microbiota, very few studies evaluated salivary pH and sIgA levels. Conclusions: The heterogeneity of the studies analyzed and the multifactorial nature of dental caries do not allow us to ensure that probiotic therapy is completely effective in preventing this pathology. Although probiotic therapy can help by regulating the microbiological factor, there are other determinants that can favor the development of caries and that are barely approached in their relationship with bacteriotherapy. Future studies that homogeneously evaluate the use of probiotics could give us a clearer idea of their effectiveness

Importancia de la guía anterior en el tratamiento de ortodoncia: Revisión de la literatura
(2020) Osorio Ayala, Lesly Damaris; Yunga Picon, Maria Yolanda; Pesantez Ibarra, Mateo Jose; Parra Calle, Maria Jose; Paredes Tenesaca, Daniela Germania; Barzallo Sardi, Vinicio Egidio
Orthodontic treatment must include both functional and aesthetic parameters to establish balance in the stomatognathic system, despite this, in many cases these criterions are not taken into consideration producing alterations at masticatory level. To achieve stability, the treatments must establish an anterior guidance which protects posterior teeth in eccentric movements, thus avoiding, contacts that can have repercussions at teeth’s level, periodontium, temporomandibular joint and oral muscles. This article aims to make known the importance of the anterior guidance in orthodontics and the consequence of avoiding this fundamental parameter of occlusion. The following literature review was carried out by a bibliographic compilation of different studies related to occlusion and function of the anterior guidance, in addition to possible consequences of its absence. It is concluded that without analyzing each factor during the functional movements of the TMJ, will not obtain the desired objectives proposed by the clinical treatment.
Melanosis Gingival: diagnóstico y terapéutica de su implicación estética. Revisión de la literatura
(Universidad de Cuenca, 2020-11-16) Cantos Tello, Paola Michelle; Osorio Ayala, Lesly Damaris; Carvajal Endara, Andrea Soledad
Gingival hyperpigmentation is produced by excessive melanin deposit, generating a dark gum coloring. Although it does not constitute a health issue, in some cases it usually represents an aesthetic problem that can affect psychologically, for which there are currently several treatment alternatives such as: surgery with scalpel, laser therapy, abrasion, cryosurgery, electrosurgery, among others. The aim of this literature review was to analyze the available information about gingival melanosis and the therapeutics that can be applied to improve the appearance of patients with this condition. Articles in English and Spanish, published during the period 2000-2020 in the PubMed, Medline, Scielo, Cochrane and Lilacs databases, were reviewed. It was concluded that the selection of the technique will depend on each particular case, however, the laser is the most relevant.
