Quiz 5

Question 1

Local contributing factors

Answer 1

Intraoral conditions or habits that increase an individuals susceptibility to periodontal infection or that can damage the periodontium in specific sites within the dentition

Question 2

Disease site

Answer 2

An individual tooth or specific surface of a tooth

Question 3

Dental calculus

Answer 3

Mineralized bacteria plaque biofilm, covered on its external surface by nonmineralized, living bacterial plaque biofilm

Question 4

Pellicle

Answer 4

Thin, bacteria-free membrane that forms on the surface of the tooth during the late stages of eruption

Question 5

Morphology

Answer 5

The study of anatomic surface features of the teeth

Question 6

Palatogingival groove

Answer 6

During natural development of some incisor teeth, this groove forms on the palatal surface of the tooth. Most frequently seen on maxillary lateral incisors

Question 7

Concavities

Answer 7

Depressions that can lead to plaque biofilm retention

Question 8

Cervical enamel projection

Answer 8

An apical deviation of the CEJ toward the direction of the furcation entrance. Flat triangular shaped projection of enamel pointing in the direction of the furcation

Question 9

Enamel pearl

Answer 9

A well defined ectopic, spherical shaped deposit of enamel found on the root surface

Question 10

Iatrogenic factor

Answer 10

Treatment that results in an inadvertent, adverse outcome

Question 11

Overhanging restoration

Answer 11

When excess restorative material extends over the cavity margin or normal contours of the tooth. Otherwise known as an overhang

Question 12

Open margin

Answer 12

A space or gap between the edge of a restoration and the natural, unprepared tooth structure

Question 13

Embrasure space

Answer 13

The space apical to the contact area of two adjacent teeth

Question 14

Prosthesis

Answer 14

An intraoral substitute used to restore missing parts of teeth, missing teeth and missing soft or hard tissues of the jaw and palate

Question 15

Biologic width

Answer 15

Refers to the zone of soft tissue occupied by the junctional epithelium and the connective tissue attachment fibers immediately apical to the JE

Question 16

Factitious injury

Answer 16

Habits that cause self inflicted injury such as tongue thrusting, mouth breathing or anything that causes damage to the periodontium

Question 17

Food impaction

Answer 17

Refers to forcing food between teeth during chewing, trapping food in the interdental area

Question 18

Tongue thrusting

Answer 18

The application of forceful pressure against the anterior teeth with the tongue

Question 19

Mouth breathing

Answer 19

The process of inhaling and exhaling air primarily through the mouth, rather than the nose, and often occurs when the patient is sleeping

Question 20

Traumatic tooth brushing

Answer 20

Aggressive, forceful use of a toothbrush in a horizontal or rotary fashion

Question 21

Dehiscence

Answer 21

A defect from traumatic tooth brushing that will result in tissue abrasion, gingival recession with loss of alveolar bone on the labial side, and subsequently root exposure

Question 22

Fenestration

Answer 22

“Window” of bone loss bordered by alveolar bone loss on its coronal aspect

Question 23

Trauma from occlusion

Answer 23

Excessive occlusal forces that cause damage to the periodontium

Question 24

Primary trauma from occlusion

Answer 24

Excessive occlusal forces on a sound periodontium with no previous history of periodontal breakdown

Question 25

Secondary trauma from occlusion

Answer 25

Normal or excessive occlusal forces are placed on teeth with an unhealthy periodontium previously weakened by periodontitis, thus contributing harm to an already damaged periodontium

Question 26

Functional occlusal forces

Answer 26

Normal forces produced during the act of chewing food

Question 27

Parafunctional occlusal forces

Answer 27

Tooth-to-tooth contact made when not in the act of eating

Question 28

Clenching

Answer 28

The continuous or intermittent forceful closure of the maxillary teeth against the mandibular teeth

Question 29

Bruxism

Answer 29

Forceful grinding of the teeth

Question 30

Frenal pull

Answer 30

Abnormal frenal attachment located in close proximity to the gingival margin will distend the gingival sulcus. Occurs most commonly on the facial surface between the max and mand central incisors and in canine and premolar areas

Question 31

Non surgical periodontal therapy

Answer 31

Describes the many non surgical steps used to eliminate inflammation in the peridontium of a patient with periodontal disease

Question 32

Interdisciplinary care

Answer 32

ADA defines this as two or more health care providers working within their respective disciplines who collaborate with the patient and/or caregiver to develop and implement a care plan

Question 33

Periodontal instrumentation (debridement)

Answer 33

Removal or disruption of plaque biofilm, its byproducts, and biofilm retentive calculus deposits from coronal tooth surfaces and tooth root surfaces to the extent needed to re-establish periodontal health and restore a balance between the bacterial flora and the hosts immune responses

Question 34

Long junctional epithelium

Answer 34

The primary type of healing in a site of attachment loss after periodontal instrumentation is through the formation of LJE

Question 35

Dentinal hypersensitivity

Answer 35

Short, sharp painful reaction that occurs when areas of exposed dentin are subjected to mechanical, thermal or chemical stimuli

Question 36

Re-evaluation

Answer 36

A formal step after the completion of non surgical therapy

Question 37

Non responsive disease sites

Answer 37

Areas in the periodontium that show deeper probing depths, continuing loss of attachment, or continuing clinical signs of inflammation in spite of the non surgical therapy provided

Question 38

Co-management

Answer 38

The shared responsibility and accountability for the care of a patient
