Ciaccio's glands Ciaccio's glands Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands ("glandulae lacrimales accessoriae") found in the lacrimal caruncle of the eyelid. They are located in the upper border of the tarsus, approximately in the middle between the extremities of the tarsal glands. Sometimes they are situated slightly above the tarsus. There are usually 2 to 5 of these glands in the upper eyelid, and their function is to produce tears which are secreted onto the surface of the conjunctiva. They are named after Italian anatomist Giuseppe Vincenzo Ciaccio (1824–1901), who described these glands in 1874. They are
Dental sealant under dental sealants, and can thus cause decay in the very teeth intended to be protected. Dental sealants are inspected during routine dental visits to ensure that they are retained in the fissures of the teeth. Damaged sealants can simply be repaired by adding new sealant material. One of the major causes of the loss of sealants in the first year is salivary contamination. On the basis of limited evidence both GIC and resin materials are equally acceptable in caries prevention, however retention rates between GIC and Resin have been shown to differ. Resin has been shown to be the
