Periodontal disease is a gum infection caused by plaque on teeth containing both bacteria and calculus (hard) deposits. These need to be removed on a regular basis to maintain gum health and to prevent teeth weakening. A routine cleaning procedure, scaling/root planing, is accompanied with post-operative soft tissue tenderness and teeth sensitivity making oral hygiene maintenance difficult during wound healing. The need for novel therapeutic approaches, such as cyanoacrylate adhesives, has been identified. It has been hypothesized that its application may provide comfort and assist patients with their daily oral self-care procedures following teeth cleaning.
The main causes of adverse pregnancy outcome(s) are reported to be maternal infection and placental, foetal, or uterine pathosis. Maternal infection and placental pathosis appear to be the most important causal factors, possibly causing pre-term labour, premature pre-term membrane rupture, or result in medically induced pregnancy interruption. There are reports of a link between poor maternal periodontal health and composite adverse pregnancy outcome of pre-term low birth weight (PLBW). however, the reason for such correlation is still not clear. In the current study the investigators will try to follow a possible path between periodontal infection and uterus physiology, by signaling out inflammatory markers that may leak from the gingival fluid into the serum and from there to the amniotic fluid. the investigators will collect GCF, serum and amniotic fluid from patients undergoing elective amniocentesis and analyse inflammatory markers in the collected samples.
aggressive periodontitis is an inflammatory disease which damage the teeth supporting structures mostly in young patients. and has genetic basis. a specific bacteria: Aggregatibacter actinomycetemcomitans (Aa) is associated with this disease, and found to damage leukocytes by using a specific leukotoxin. in the research the investigators are aiming to find molecular and immunological basis to aggressive periodontitis.
Many physically handicapped patients at the dental department, Toronto Rehabilitation Institute(TRI) have considerable gingival inflammation and breath odour because of the inability to effectively handle a toothbrush. These patients have considerable periodontal disease. There is a concern that these pathogens may have a detrimental effect on wound healing in other areas of the body. Hypothesis: Patients attending the dental department at TRI that are treated with the antibiotic-antifungal rinse containing metronidazole and nystatin will show substantial decrease in periodontal disease as measured by bleeding points and pocket depth when compared to the group that continues to use their regular oral hygiene methods (control group).
