Gingival condition in areas of minimal and appreciable width of keratinized gingival

Abstract

Sixteen dental, dental hygiene, and dental assisting students and dental faculty members who had contralateral or unilateral areas of minimal (less than or equal to 1.0 mm) and appreciable (greater than or equal to 2.0 mm) widths of keratinized gingiva on mid-buccal plaque-free surfaces of mandibular bicuspids were examined. Gingival exudate amounts and clinical inflammation based on color change and/or swelling and bleeding on probing were evaluated. The results showed that gingiva with "appreciable" width as well as gingiva with "minimal" width of keratinized tissue exhibited only minute amounts of gingival exudate. Also, there were generally no clinical signs of inflammation for both types of tissue. From the groups of 16, six subjects were selected who had contralateral pairs of minimal and appreciable keratinized gingiva. They were instructed to cease oral hygiene in the lower bicuspid area for 25 days. At day 0, 4, 7, 11, 14, 18, 21, and 25, plaque, gingival exudate, and clinical gingival inflammation were evaluated. Results revealed increases in plaque, gingival exudate scores and clinical gingival inflammation over the 25-day period with no apparent difference between the areas with minimal and appreciable width of keratinized gingiva.

Determinantes del diagnóstico periodontal

“…Hoy en día sigue en debate la necesidad del aumento del volumen de encía queratinizada y esto queda a consideración del clínico. Sin embargo, en condiciones de higiene oral óptimas, sitios con encía delgada y poca encía queratinizada es posible mantenerlos saludables durante largos períodos de tiempo (30,31,32) . La necesidad de aumento de encía queratinizada dependerá de cada caso en particular, evaluando posición dental, presencia de recesiones, higiene oral, necesidades restaurativas, presencia de frenillos sobreinsertados, etc.…”

Free gingival grafts to increase keratinized tissue: a retrospective long-term evaluation (10 to 25 years) of outcomes

“…[1][2][3][4] In an observational study, Lang and Löe 5 reported that despite the fact that the tooth surfaces were free from plaque, ''all surfaces with less than 2.0 mm of keratinized gingiva exhibited clinical inflammation and varying amounts of gingival exudates.'' Other investigators [6][7][8] failed to find a similar association and reported that it is possible to maintain healthy marginal tissues, even in areas with a reduced or missing keratinized gingiva.…”

Aplicación clínica de la matriz dérmica acelular para prevenir recesiones gingivales

“…La necesidad de incrementar la encía queratinizada se ha reducido considerablemente debido a que se ha demostrado que cantidades mínimas de ella son compatibles con condiciones periodontales saludables cuando se realiza un efectivo control de placa bacteriana (1)(2)(3)(4). Esto implica que el objetivo primordial del la cirugía plástica periodontal es cubrir las superficies radiculares expuestas cuando esta condición causa al paciente problemas estéticos, hipersensibilidad dentinal, caries radicular o dificulta una adecuada remoción de placa bacteriana (5).…”
