Objective: to determine the influence of perceived academic stress on the oral microbiota and salivary pH in the fifth year students of the Faculty of Dentistry - UMSS in the second rotation of the 2018 term. Methods: longitudinal descrptive and prospective study. We worked with 26 students, the following were made at the beginning and at the end of the term: Questionnaire of Stress Perceived (CPE), buccal swab (to identify microbiota) and sample taking of saliva (to determine pH). Results: psychological test, at the beginning: 69,2% level 2 “stressed” and 23,0% level 3”moderately stressed” , 7,6% of students level 1 “little stressed”. At the end: 46,1% level 3”moderately stressed”, 30,7% level 2 “stressed”, and 19,2% level 4 “very stressed”, 3,8% level 1 “little stressed”. Salivary pH levels, fist shot: average level was 6,9. Second shot: average level was 6,20.  Microbiological test, first shot: Streptococcus viridans were developed in 26 cultures, in 3 Staphylococcus spp, in 3 Candida albicans, in 2 Escherichia coli and in 1 Staphylococcus aureus. In the second shot there was a significant increase in bacterial development in all cases. Salivary pH analysis, first intake: average value 6,79. Second shot: average value 6,20. Conclusions: the levels of academic stress perceived by the students of the Faculty of Dentistry - UMSS are high at the end of the second rotation of the 2018 management, consistent with the increased development of Streptococcus viridans and Candida albicans, accompanied by a marked decrease in salivary pH.
