Introduction:

making a transition towards the goal of a healthy periodontal population, with strengthening in the delivery of the preventive promotional component is a challenge for dentistry professionals.

Objective:

to evaluate the effectiveness of an educational and curative intervention strategy for chronic inflammatory periodontal disease in adolescents.

Methods:

a prospective, longitudinal and intervention study was carried out through a pre-experiment at “13 de Marzo” Basic Secondary School in Placetas, Villa Clara from January 2018 to September 2019. The study population consisted of 117 adolescents from the 7th grade and their parents, as well as, 16 teachers who worked with them. Periodontal condition, level of information on periodontal disease, oral hygiene and effectiveness of the strategy were the variables studied. Descriptive statistics, mainly absolute frequencies and percentages, and Wilcoxon signed - rank test, as a non-parametric test were used.

Results:

69.2% of the adolescents had gingivitis, and 65.8% had an insufficient level of information. The educational and curative intervention strategy for chronic inflammatory periodontal disease consisted of four stages: diagnosis, strategic planning, implementation and evaluation, with an educational component (educational program) and a curative one. It was characterized by short- , medium- and long-term objectives, as well as the actions to fulfill those objectives.

Conclusions:

the strategy was assessed by specialist criteria as adequate, and it was considered effective after its application.
