ABSTRACT
Resumen Introducción: La recesión gingival puede estar relacionada con la enfermedad periodontal o condiciones mucogingivales ocasionando hipersensibilidad, caries radicular y problemas estéticos. La combinación de la técnica en túnel y el injerto de tejido conectivo subepitelial puede considerarse una opción para el tratamiento de recesiones gingivales múltiples. Presentación del caso: Paciente de sexo femenino de 38 años de edad, al interrogatorio refiere tener hipersensibilidad dentaria en los dientes superiores (13, 14, 22, 23, 24) que presentan recesión gingival. A la valoración periodontal se observan recesiones gingivales clase I y III de Miller en cuadrante I y II, el diagnóstico periodontal es periodonto sano. Para realizar la cobertura radicular se planea combinar la colocación de injerto de tejido conectivo subepitelial con técnica en túnel, siendo un procedimiento adecuado cuando las papilas interdentales son amplias, además de ser una técnica de alta predictibilidad para lograr la cobertura radicular. En este caso, se decidió iniciar por el segundo cuadrante, ya que eran los sitios con mayor hipersensibilidad dentaria y un mes después realizar el tratamiento en el primer cuadrante. Conclusiones: La técnica que se aplicó permitió eliminar la hipersensibilidad dentaria en un 100% considerando como única desventaja el doble sitio quirúrgico del sitio donador. Es importante mencionar que además de lograr mejoría en la hipersensibilidad dentaria, se mejoraron las condiciones estéticas.
Abstract Introduction: Gingival recession can be associated to periodontal disease or muco-gingival conditions causing hypersensitivity, root caries and esthetic problems. A combination of the tunneling technique with sub-epithelial connective tissue graft can be considered an option for multiple gingival recession treatment. Case presentation: A 38 year old female patient who informed of suffering hypersensitivity in upper teeth (13, 14, 22, 23, 24), exhibiting gingival recession. Periodontal evaluation revealed Miller class I and III gingival recessions in quadrants I and II. Periodontal diagnosis was healthy periodontium. In order to achieve root coverage, placement of sub-epithelial connective tissue graft with tunneling was planned. This represents a suitable procedure in cases when interdental papillae are wide, moreover, it constitutes a high predictability technique in order to achieve root coverage. In the present case, it was decided to initiate treatment on the second quadrant since it lodged sites with greater dental hypersensitivity, to be followed a month later by treatment on the first quadrant. Conclusions: This applied technique allowed for 100% elimination of tooth hypersensitivity, only considering a disadvantage the double surgical site of the donor site. It is important to mention that, in addition to achieving improvement in tooth hypersensitivity, esthetic appearance was improved.
ABSTRACT
PURPOSE: The present study was performed to evaluate the effect of hydroxyapatite dental paste on tooth hypersensitivity compared to other materials. MATERIALS AND METHODS: In the general fluoride dental paste, strontium fluoride dental paste and hydroxyapatite dental paste, patient-performed VAS and VAS(ice test) were measured at baseline, 1weeks and 4weeks. RESULTS: 1. In patient-performed VAS, there were significant differences reducing of tooth hypersensitivity between general fluoride toothpaste and hydroxyapatite toothpaste. 2. In operator-performed VAS(ice test), there were significant differences reducing of tooth hypersensitivity among each group, between general fluoride toothpaste and hydroxyapatite toothpaste and between general fluoride toothpaste and strontium fluoride toothpaste. CONCLUSION: In conclusion, hydroxyapatite toothpaste can be applied for control of tooth hypersensitivity.
