Gingival flap-split thickness flap, a combined procedure. Clinical study in humans and dogs.

1. The combined procedure can be performed to handle the two very common periodontal problems (bone defect, high frenum, and/or high muscle insertion) when present in the same area. 2. Healing was uneventful, since only four postoperatory complications were observed in 40 surgeries performed, and none of these complications was in humans. 3. Macroscopically, the surgical area showed normalcy 1 week after the procedure. 4. It is a procedure very easy to perform and shows uneventful postoperative healing. There is no patient discomfort.

Argyria: clinical implications of exposure to silver nitrate and silver oxide.

This article reports the clinical findings in a work force of 30 individuals who were exposed to silver nitrate and silver oxide. Six individuals had argyria and 20 had argyrosis (deposition of silver in the eye). Measurements of blood silver levels were included as part of the examination. The results of this examination generally support the benign nature of argyria, although the question of silver causing a decrement in kidney function and night vision is not settled. Periodic slit lamp examinations as well as monitoring of silver air concentrations are necessary to assure that engineering controls are actually limiting worker exposure to silver.

Rebuilding of microvascularization following surgical gingival elimination by split flap. Study by perfusion and diaphanization.

1. Intra-arterial vital perfusion was used in dogs to study the rebuilding of the large amount of gingiva and its vascularization, which were removed surgically by split flaps. 2. Visualization of the reconstruction of the microvascularization could be observed through thick (400 mu) sections cleared in methyl salicylate. 3. The periosteal vessels and the vascular plexi of the dentogingival junction were the only vessels remaining after the surgery, and served as progenitors for the rebuilding of the vascularization of the new soft tissue complex. 4. After 48 hours the cut vessels were closed and new capillaries were beginning to form. An intense superficial vascularization was connected by multiple vessels to the periosteal vasculature (4 days), showing the largest number of superficial blood vessels after 7 days, when the area was primarily re-epithelialized.

Split thickness flap, apically replaced, with protected linear periosteal fenestration.

The split thickness flap, apically replaced, with internal linear periosteal fenestration, is a combination of two known techniques. This procedure is another choice to solve mucogingival problems. The advantages in addition to securing a firmer bond of periosteum to bone and mucosa to periosteum at the selected position are: there is no bone exposed, healing is apparently faster and postoperative pain is minimal. An experimental work, carried out on dogs to study the histological reactions after this procedure, is in progress. The results of these observations will be reported in a future publication.
