Background: Sometimes gingival retractions are associated with high muscular tensional forces and shallow vestibules. Such retractions cause periodontal problems to patients due to the cleaning access limitations. Edlan Mejchar vestibuloplasty technique allows controlling, in one intervention and a single surgical field, etiological factors and a creeping gingival attachment by eliminating tensional forces. Purpose: To describe the effectiveness of Edlan Mejchar technique to solve gum retractions caused by tensional forces in four clinical cases. Description of cases: Four patients with gingival retractions in lower incisors and little adhered gingiva due to lower lip frenulum tension seek dental treatment. Edlan Mejchar vestibuloplasty was the surgical treatment chosen, which consisted of supraperiosteal incisions and internal dissections in connective tissue. Results: The percentage of root coverage achieved was close to 60% and abnormal frenulum insertions were eliminated. Conclusion: Vestibuloplasty through Edlan Mejchar technique showed favorable results in the cases described in which the labial frenum exerted tensional forces on the periodontium of lower anterior teeth.

Background: Dental avulsion is a rare traumatic lesion in permanent teeth. External root resorption is a common event after reimplantation of an avulsed tooth. Purpose: To report a case of two reimplanted teeth with satisfactory results after controls during 26 weeks. Case report: Clinical management of an 8-year-old boy that seeks attention in the clinic of the Postdoctoral Program in Endodontics of University of Cartagena with background of avulsion of both central upper incisors. The teeth were prepared up to a type K # 50 file, medicated with calcium hydroxide and later filled with MTA. Results: Healing was observed on the root surface with reduction of the external radicular resorption after a 26-week follow-up. Conclusion: External radicular resorption can be counteracted as long as its handling was performed professionally within parameters of time and biological conditions. [ABSTRACT FROM AUTHOR]

Aim: To understand the implementation process of the education communication strategy (ECS) of the IMSS Oportunidades Program from the perception of its institutional actors in a highly marginalized area of Mexico. Methodology. A qualitative instrumental case study was conducted in April 2009 to explore in detail characteristics of an ECS in a remote indigenous context in the south of the northern Mexican State of Chihuahua. The field work was carried out in the communities of Guachochi, Baquiriachi and Cabórachi. Empirical and contextual information related to the study aim were collected using the methodological and technical applications of ethnography, key informant interviews, and non-participant observations. Result. Within this community background, the operative meaning of the ECS of the IMSS-Oportunidades program oscillated between the vertical and the horizontal. The existing co-responsibility between the two main program players -the medical and community caretakers- operate as the central axis for exercising the development of health promotion activities and support the development of the ECS. Conclusions. The positive impact of the Program and its ECS was recognized by the institutional actors interviewed, which seemed to be the result of a continued coordination and participative work for decades between the community and the health teams involved in intervention activities at community level.
