Objective: To determine the most frequent position of third mandibular molars, according to Pell and Gregory classification in panoramic x - rays at the -ZERO, Huancayo 2018. Material and methods: Regarding the methodology used by the sequence of studies period, it is retrospective crosssectional and according to its level it was descriptive. The sample was not probabilistic, for convenience, consisting of 396 panoramic radiographs in an age range of 18 to 40 years. Results: A total 792 third mandibular molars, excluding missing parts, there is a higher prevalence of class II position B with 37.5 percent (n = 297), followed by class II position A with 22.5 percent (n = 178) and class I position A with 18.8 percent (n = 149) of the total. Conclusions: There is a higher prevalence of class II position B, in both sexes and in most age groups in the panoramic x-rays evaluated.

Objective: To evaluate the effect of using a mouthwash based on natural substances on the length of stay in hospital for Covi-19 patients. Material and Methods: Applied observational experimental study. For the statistical analysis of the length of stay and comparative analysis of patients hospitalized with Covid-19 who used the rinse and those who did not, the Student T test was used. Results: The average hospitalization time for Covid-19 patients who did not use mouthwash was 10.14 days, while in Covid-19 patients who used mouthwash, the hospitalization time was 8.78 days, however, the difference found It was not statistically significant. (p=0.155). Conclusions: The use of mouthwash based on natural substances reduced the length of hospital stay of patients admitted for Covid 19 by 1.36 days.

Objectives: To describe the temporomandibular disorders, most prevalent, according to the Helkimo index in the students of Franklin Roosevelt, private university of Huancayo, evaluated at the beginning of the academic semester 2018-I.
