    Estrategias para la remineralización del esmalte: una descripción general de las revisiones sistemáticas

    Introduction: Remineralizing agents are alternative to oral treatment that induce mineral profits; Therefore, the treatment effectiveness is of scientific necessity. Objective: The aim of this systematic review is to evaluate the methodological quality of systematic reviews on the effectiveness in the remineralization of incipient lesions in enamel through different therapeutic methods using AMSTAR 2. An overview of systematic reviews (SRs) of randomized controlled trials (RCTs) and in vitro studies was performed. Methods: The search was performed using four digital databases and the grey literature. SRs on the remineralization of white spot lesions (WSLs) through different therapeutic alternatives were included. Results: The results evaluated were changes in the enamel structure. Eleven SRs were included. Two studies reported that casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) had greater remineralization potential than other compounds. Two studies found no significant difference between CPP-ACP and fluoridated agents. Four studies reported on the efficacy of fluoridated agents. One study found no difference between CPP-ACP and CPP–amorphous calcium fluoride phosphate (CPP-ACFP). Three studies did not yield conclusive results. Conclusions: Methodological quality was classified as high risk of bias for seven SRs and moderate risk of bias for four SRs. With a confidence level ranging from moderate to low, fluoridated compounds, nonfluoridated compounds, and combined compounds in randomized controlled trials show a potential to remineralize WSLs. Nonfluoridated compounds in in vitro studies (CPP-ACP) show statistically significant changes in enamel structure, but these results should be interpreted with caution.

    Prevalencia de recesión gingival y factores asociados en estudiantes entre 18 y 25 años de la Facultad de Odontología de la Universidad de Cuenca, 2015-2016
    (2016) Brito Chicaiza, Christian David; Pesántez Chacón, David Patricio; Carvajal Endara, Andrea Soledad
    Introduction: The gingival recession (GR) is defined as exposure of the root surface by apical migration of the position of the marginal gingival, which can cause blemishes, dentinal hypersensitivity and root caries. Objective: To determine the prevalence of gingival recession and associated factors in students of the Faculty of Dentistry at the University of Cuenca, in the period 2015- 2016. Materials and Methods: A cross-sectional study on 131 students aged 18 to 25 who met the inclusion criteria, selected by simple randomization. A clinical examination was carried out and a questionnaire was applied to determine the prevalence of GR and possible associated factors such as, periodontal biotype, modified gingival index, subgingival restorations, oral hygiene, after orthodontics, toothbrushing. Results: The prevalence of GR was 64,1 %; without difference in the gender (64,3 % in males and 64 % females). A statistically significant association was found between vestibular GR a modified gingival index value of 0 (p = 0,04) and the type of toothbrush with medium bristles (p = 0,03). Other factors evaluated showed no significant association. Conclusions: The prevalence of GR was 64,1 %.The most affected teeth were the lower premolars. Of the recessions found the 98% showed Miller class I. According to the dimension in millimeters 83,2 % had 1mm; the vestibular surface was the most affected. Significantly associated factors were the type of toothbrush with medium bristles and modified gingival index value of 0 with vestibular GR
