the shaping of the peripheries of a dressing by manual manipulation of the tissue adjacent to the borders to duplicate the contour and size of the vestibule

Back 1

border mold

Front 2

mode of self-cure or setting of a dressing in which the ingredients unite in a chemical process that starts as son as the blending is complete; the setting time is influenced by warm temperature and the addition of an accelerator

Back 2

chemical cure

Front 3

to approximate, as the edges of a wound; bring edge to edge with no overlap

Back 3

coapt

Front 4

constituent of clove oil; used in early periodontal dressings with zinc oxide for its alleged antiseptic and anodyne properties; more recently found to be toxic, to elicit allergic reactions, and to hinder, more than promote, healing

Back 4

eugenol

Front 5

the termination of bleeding by mechanical or chemical means or by the complex coagulation process of the body that consists of vasoconstriction, platelet aggregation, and thrombin and fibrin synthesis

Back 5

hemostasis

Front 6

a process by which water slowly penetrates the suture filaments, causing breakdown of the suture's polymer chain; yields a lesser degree of tissue reaction

Back 6

hydrolysis

Front 7

application of a wire or thread (suture) to hold or constrict tissue

Back 7

ligation

Front 8

presence of potentially pathogenic microorganisms; opposite of asepisis: the absence of infectious material

Back 8

septic

Front 9

a stitch or series of stitches made to secure apposition of the edges of a surgical or traumatic wound

Back 9

suture

Front 10

a suture that holds the margins of an incision close together

Back 10

suture apposition

Front 11

the fusion of a suture material to the needle, which allows for a smooth eyeless attachment; the suture will then pass through the tissue as smoothly as possible

Back 11

swage

Front 12

amount of strength the suture material will retain throughout the healing period; as the would gains strength, the suture loses strength

Back 12

tensile strength

Front 13

light activation using a photocure system; shorter curing time than self-cure; does not start setting until the light is activated, thereby allowing longer working time for adapting the dressing material

Back 13

visible light-cure

Front 14

A ______ is a strand of material used to ligate blood vessels and approximate tissue.

Back 14

suture

Front 15

Functions of Sutures

Back 15

• Close Periodontal Wounds and Secure Grafts
• Assist in Maintaining Hemostasis
• Reduce Posttreatment Discomfort
• Promote Primary Intention Healing
• Prevent Uderlying Bone Exposure
• Protect Healing Surgical Wound from Foreign Debris and Trauma

Front 20

developed to reduce tissue reactions and unpredictable rates of absorption commonly found in natural sutures

Back 20

synthetic

Front 21

approximate tissue until wound heals sufficiently to endure normal sress

Back 21

absorbable sutures

*implant flap closure*

Front 22

digested by body enzymes

*surgical gut & chromic gut*

Back 22

natural absorbable sutures

*used for extraction socket & bone grafting*

Front 23

broken down by hydrolysis

Back 23

synthetic absorbable sutures

Front 24

not digested by body enzymes or hydrolyzation; must be removed within specific time period

Back 24

nonabsorbable sutures

Front 25

Back 25

natural nonabsorbable

Front 26

nylon, polyester, polypropylen

Back 26

synthetic nonabsorbable

Front 27

The diameter of sutures ranges from ____ to _______.

Back 27

1-0 to 11-0

Front 28

More zeros the ____ the diameter and fewer zeros equals ______ diameter.

Back 28

smaller

larger

Front 29
