Gingival margin

Gingival margin

The gingival margin refers to the edge of the gum tissue that surrounds and covers the tooth, which is located at the cementoenamel junction (CEJ). Gingival recession, which is the displacement of the gingival margin away from the CEJ, can occur due to either high or low oral hygiene standards and can lead to root surface exposure. This displacement can also affect dentin bonding and increase microleakage at the gingival margin.From: Biodental Engineering V [2019], Comparative Evaluation of Cavities Disinfected with Ozone Gas and Photodynamic Therapy and Restored with Two Different Reinforced Glass Ionomer Cements on Microleakage and Color Change [2022]

Gingival recession, which is clinically manifested by an apical displacement of the gingival margin from the cementoenamel junction (CEJ), are common in populations with high oral hygiene standards (Sangnes and Gjermo 1976, Serino, Wennstrom et al. 1994, Matas, Sentis et al. 2011) or with low oral hygiene standards (Baelum, Fejerskov et al. 1986, Loe, Anerud et al. 1992) and can leading to root surface exposure. (Wennstrom 1994).

This may be due to the difference in the bonding strength of the enamel and dentine materials. The gingival edge of class V cavities is mainly located in dentin which has higher moisture. This may affect dentin bonding and increase microleakage at the gingival margin. Studies on microleakage of reinforced glass ionomer cements after PDT are limited. Since this method is new, more studies on PDT are needed.
