Meibomian gland been shown to reduce inflammation and improve the gland function in patients. Meibomian gland probing is also used on patients which experience deep clogging of the glands. Meibomian gland dysfunction may be caused by some prescription medications, notably isotretinoin. Meibomian gland The Meibomian glands (often written with a small "m" and also called tarsal glands) are a holocrine type of exocrine glands, at the rim of the eyelids inside the tarsal plate, responsible for the supply of meibum, an oily substance that prevents evaporation of the eye's tear film.

Dental sealant on the tooth, rather than the decay experienced in sealed and unsealed teeth. The ability of a pit and fissure sealant to prevent dental caries is highly dependent on its ability to retain on the tooth surface.

The most common reason for sealant failure is salivary contamination during sealing placement. Other factors include clinician inexperience, lack of client co-operation, and less effective sealant material used. Sealants may be in conjunction with fluoride
