Application of apical negative pressure irrigation in the nonsurgical treatment of radicular cysts: A case report.

Background: Radicular cysts are one of the most common odontogenic cystic lesions found in the jaw. Nonsurgical treatment of large radicular cysts is a topic of ongoing debate, and there is still no clear consensus on the most effective therapies. The apical negative pressure irrigation system aspirates the cystic fluid and releases the static pressure in the radicular cyst, representing a minimally invasive approach for decompression.

[Experimental evaluation of pure traditional Chinese medical mouth rinse on skin and mucosa stimulation and bacteriostatic-bactericidal effect].

Purpose: To observe the stimulating effect of pure traditional Chinese medical mouth rinse (PTCMMR) on skin and mucosa and to evaluate the efficacy of PTCMMR on inhibiting and killing oral common bacteria.

Methods: PTCMMR and normal saline (NS) were separately dripped onto 14 five-month rabbits' left and right eyes for 7 days, and were smeared on the left and right side of buttocks, abdomens, back of 10 seven-month guinea pigs (after hair removal) once a day for comparison between the two sides. Five animals were sacrificed after 3 and 7 days of smearing to make pathological sections.
