Recently, fluid dental resins have been used in orthodontics, with the purpose of providing bioprotection over mini-implants to diminish the areas of traumas on the adjacent gingival tissues [10].
Peripheral blood (PB), sub-gingival dental plaque, synovial fluid (SF) and synovial tissue samples were collected from 69 patients with active knee arthritis (32 with RA and 37 with other arthritides, of which 14 had undifferentiated peripheral inflammatory arthritis - UPIA).
Compared with other tissues (adipose tissue, cord blood, synovial fluid, dental pulp, dermis, and muscle), bone marrow (BM) has been identified as a common source of MSCs for both experimental and clinical applications, and BMMSCs are also capable of differentiating into odontoblast-like cells [ 1– 6].
Either gastric fluid or dental plaque PCR is as reliable as C-UBT for H. pylori detection.
Either gastric fluid or dental plaque fqPCR is as reliable as C-UBT for H. pylori detection.
With further studies, fqPCR in dental plaques or gastric fluid obtained from nasogastric tube can be potentially validated as an alternative non-invasive test for H. pylori detection.
hMSCs for the first time were reported in the bone marrow and till now they have been isolated from various tissues, including adipose tissue, amniotic fluid, endometrium, dental tissues, umbilical cord and Wharton's jelly which harbours potential MSCs.
However, both gastric fluid and dental plaque fqPCR only detected 32 (23.2%) and 30 (21.7%) children with H. pylori infection respectively and was significantly less sensitive than gold standard (P<0.05) but as sensitive as C-UBT.
Isolation of MSCs could be achieved from almost every type of tissue, including bone marrow, adipose tissue, muscles, liver, dental pulp, placenta, amniotic fluid, and menstrual blood, or umbilical cord blood [ 5, 6].
Cysteine cathepsins are derived from the dental pulp via dentinal fluid and can cleave C-terminal telopeptide of type I collagen [ 20], possibly exposing the collagenase cleavage site, after the exposure to the acids.
Both gastric fluid and dental plaque fqPCR only detected 32 (23.2%) and 30 (21.7%) children with H. pylori infection respectively and was significantly less sensitive than mucosa fqPCR (P<0.05) but was as sensitive as non-invasive UBT.
