Perio ch 8

defined as clinical attachment loss with subsequent bone loss

What is the diagnosis of periodontitis based on?

periodontitis is catoragized as

Primary risk factor for periodontitis

last structures to be lost in PD

plasma cell/antibody mediated

occurs with clinical connective tissue attachment loss to the root surface and the apical migration of the apical aspect of the JE along the root surface taht was previously occupied by connective tissue

What are developed in PD pockets between the root surface and the gingiva

__and__migration of the junctional epithelium continues and as this epithelium separates from the root surface

Two types of periodontal pockets

What distinguishes the two types of pockets

If the base is coronal to the crest of bone

base is apical to the crest of bone

Where is the JE in gingivitis and healthy gingiva

how is teh texture of cementum without PDL fibers

Is it necessary to remove the roughness of cementum in order to remove the endotoxins, bacteria, and other byproducts?

Bone loss involves inflammatory cells including

Substances involved in bone resorption (4)

what release prostoglandins?

What do prostaglandins do

most important in periodontal distruction

what do endotoxin do

What do macrophages release

What can IL-1 stimulate the production of

cytokines and prostaglandis stimulate collagenase which does what?

Does pocket formation and bone loss occur in all areas of the dentition at the same time?

Is the degree of bone loss aloways correlated with the depth of periodontal pockets

They types of pockets that form and the pattern of bone loss depend on what?

Where is bone most vascular?

two patterns of bone loss

Bone loss that occurs from its outer aspect buccal and lingual walls. lost equally on the surfaces of two adjacent teeth. Deepest portion of the pocket is located coronal to the alveolar crest

Bone loss that occurs when teh inflammation travels directly formt eh gingiva into the peridontal ligament and then the bone. occurs at different rates aroun the tooth...more rapid ont eh side of the tooth than the other. the deepest poriton of the bony defect is apical to the alveolar bone crest

A three wall defect that wraps around the tooth and involves two or more adjacent root surfaces is referred to as

classified according to the number of osseous walls surrounding the pocket

three bony walls remaining interproximally or facially or lingually and the tooth forming the fourth wall

Infrabony defects are usually composed of what bone

what about intrabony

how do you determine if it is intra or infra

a three wall defect that wraps around the tooth and involves two or more adjacent root surfaces is referred to as

has two bony walls remaining

the most common angular bony defect

has one wall remaining

usually occurs interdentally

if teh remaining wall is the proximal wall the defect is referred to as a

outside a __mm circle, bone loss occurs

Bone destruction occuring where thiere is a wide interdental septume and more thatn 2 mm of with is lost will be verticl or horizontal?

bone destruction occuring where the interdental septum is narrow, less than 2 mm, results in vertical or horizontal

Teeth in anterior are usually

molars are usually

most common form of PD

has a slow rate of progression

in order to develope chronic pd what must be present first

is chronic pd consisered a specific bacterial infection?

Presence of what bacteria indicates a high probability that pd is presence

Local risk factors for pd

chronic Pd is classified according to

defined as the number of sites affected

extent is divided into

how much disease has occured

severity is calculated from the

mild
moderate
severe

features of chronic periodiontisi include

is mobiity always evident in CHronic PD

established risk factors for PD

nicotine in tobacco causes

smokers appear to have decreased..

decreasedPMN migration into the oral cavity leads to

rapidly progressive form of periodontitis

common features of localized and generalized aggressive periodontisi

secondary features that may be present include the following

features of localized aggressive pd

features of gineralized aggressive periodontitis

a distinguishing feature found in AfP that is not seen in chronic PD is the presence of

Periodontisis can be linked to

children with GAgP are more pron to

Plaque accumulation is minimal
bone los is not super rapid
usually no accompanying infection
slight gingival inflammation

there is a defect in PMN chemotaxis and impaired phagocytosis in what percent of patients

Predominant bacteria in LAP

high numbers of what are in the subgingvial pocke associate with LAP which invade the soft tissue

what personce of LAP have hgih counts of Aa

patient previously treated conventionally and do not respond favorable to therapy and are concidered to be resistant to tx

patient with poor compliance are termed

high numbers of which bacterias are found in refractory pd

Lesions of the PDL and adjacent alveolar bone may originate from interactions of the periodontium or tissues of the dental pulp. This is periodontitis associate with what?

Which systemic diseases contribute to periodontitis

collective term for soft-tissue inflammation surrounding an inplant

term used to describe reversible inflammation in the gingiva around a functioning implant

Tx of all types of periodontal diseases begins with

may be required for pocket elimination or reduction

Do patients with chronic periodontitis require systemic antibiotics?

In selected cases if the patient is having a difficult time with homecare, what may be implicated

do patients with aggressive periodontits require systemic antibiotic during scaling and root planing and periodontal surgery

why do patients with aggressive periodontitis require systemic antibiotic require med

What do to with diabetic patients who have PD
