Q

periodontal disease

A

Loss of connective tissue attachment
Loss of crestal alveolar bone. This loss of alveolar bone occurs through bone resorption (breaking down)
Bacteria and their byproducts break down the interface between the Sulcular epi and cause detachment of the JE and CT
Pockets deepen as a result of collagen breakdown in the gingival CT by enzymes such as collagenase.
Bacteria release a number of chemotactic substances that increase the flow of neutrophils in the gingival sulcus.
Neutrophils react with bacteria, producing suppuration

elimination of local etiology usually surgery in combination with systemic antibiotics

62
Q

Refractory periodontitis

A

Despite appropriate normal treatment, the perio condition of the patient continues to worsen and is not arrested.
Either single or multiple sites.
Bacteria involved seem to be very resistant to normal therapies. Could also be a host response deficiency.

~systemic condition is causing the problem and increase pt risk
~ modify or amplify the host response (change or increase)
~immune system can not fight it off
~examples: Down’s syndrome, Leukemia, AIDS, Papillon-Lefevre syndrome, Chediak-Higashi syndrome

65
Q

down syndrome

A

~periodontitis as a manifestation of systemic disease
~Genetic
~Mental retardation
~Abnormal PMN function (don’t have first responders if you have down syndrome, chemotaxis is also altered)
~Chemotaxis altered therefore PMNs can’t get there

66

~Mostly mandible
~Bisphonates
~Not normal

75
Q

Tobacco use

A

~Direct impact on periodontal disease (heat in mouth)
~Tissue become dry and mouth becomes dry
~Heat and dry cause vasoconstriction (lack of blood flow) because smoke contains cytotoxic and vasoactive components
~When pt stops smoking pt starts bleeding within 4-6 weeks (isn’t constricted anymore)
~Byproducts of smoke get into sulcus and act as an irritant
~ risk factor for perio (increase attachment loss, increased tooth loss)
~ diminished neutrophil function (doesn’t fight infection) and impaired fibroblast function and a reduced capacity of the periodontal tissues to repair themselves.
~fibrotic tissue

76
Q

Has Periodontal disease and now at risk for other conditions such as

A

Diabetes
Cardiovascular
Pre-term babies

77
Q

Diabetes Mellitus

A

Type I: insulant
Type II: insulant resistant
Controlled vs. uncontrolled
HB1C 7
FPG 126
Stress affects blood glucose
Diabetic that is control not a greater risk for perio
Uncontrolled puts at risk for perio and makes perio worse
Even if it is Controlled there are periods of time that it is not controlled
The goal of treatment is to control blood glucose level
Poor wound healing
Poor nutrition
Bacteria loves sugar

78
Q

increased blood glucose

A

Glucose in crevicular fluid
Reduced PMN’s…1st line of defense (poor wound healing)
2-3 times greater risk for developing perio

79
Q

what to ask a diabetic pt

A

what are your levelsdid you eatwhat typemedicationsdid you take the medicationswhen did you take the readings of levels

80
Q

Cardiovascular disease

A

Systemic inflammatory response
Inflammation within arteries
C reactive proteins – marker for inflammation
Link between perio and cardiovascular disease

81
Q

Pre-term babies

A

less than 37 weeks
low birth weight
Prostaglandins (destroy bone, hormone like structure from in __)-> osteoclasts
Already have too many prostaglandins and will cause pre mature baby aka low birth weight babies
There is a link between perio mouths and low babies weight babies
Uterus contracts from more prostaglandins

82

83
Q

Necrotizing Ulcerative Periodontitis

- how is it different than NUG

A

NUP
Usually associated with an immune compromised disorder such as HIV.
The only difference is that bone is lost

84
Q

Abscess of the periodontium

A

Acute: an acute localized purulent infection of the periodontium.

Perio pocket becomes occluded and an infection is allowed to become localized into an acute infection in the adjacent tissues.

Rapid bone loss can occur with pain and swelling.

Blister like lesions -> circumscribed/ fluctuant (when you push it, it comes back) , filled with puss-> neutrophils are dying and give off pus, can but acute or chronic, periodontal abscess -> rapid bone loss,

85
Q

Abscess of the periodontium

A
  • Perio pocket becomes occluded and an infection is allowed to become localized into an acute infection in the adjacent tissues.
  • Rapid bone loss can occur with pain and swelling.
  • Blister like lesions -> circumscribed/ fluctuant (when you push it, it comes back), filled with puss-> neutrophils are dying and give off pus, can but acute or chronic, periodontal abscess -> rapid bone loss
86
Q

fistula

A

draining abscess

87
Q

gross scaling

A

supra scaling (bad because you may miss the calculus underneath) -> causes a periodontium abscess

88
Q

Acute Abscess of the periodontium

A

-Acute: an acute localized purulent infection of the periodontium.
-usually associated with deep pocket
-fistula
-pain
gross scaling
-tx: Radiographic analysis
Repair potential is great because of an acute phase reaction.
Film will help but first probe (a really deep pocket) quick bone destruction
Treat-> debride, local, might be surgically cut to making into a fistula(pus will come out), possibly antibiotics
Usually painful

89
Q

Chronic Abscess of the periodontium

A

Clinically appears like an acute abscess…patient has no pain

Can be fistulaed / and be filled (goes back and forth)

90
Q

Gingival abscess

A

Similar to periodontal abscess except only contained in the soft gingival tissues
Usually caused by invasion of a foreign body forced into the gingival sulcus
No bone or attachment loss.
less of a concern
popcorn gets stuck

91
Q

Pericoronitis

A

Tissue over tooth (usually third molar)
Operculum -> tissue of the most distal tooth
Infection starts under the tissue
Is in pain
Debride the area (doesn’t always need a flap, but may)
Irrigator (antimicrobial)
Makes them feel better until get oral surgernt removes it
Palative treatment
Fever -> antibiotics
Flap of tissue distal to the 3rd molar

TREATMENT- consists of opening tissue via a flap and careful debridement of the pocket of infected area. No antibiotics are given unless there is evidence of facial cellulites (generalized area of inflammation) or if the patient has a fever.

92
Q

palative treatment

A

treat the symptoms

93
Q

Endodontic abscess

A

Very difficult to distinguish from a perio abscess in terms of symptoms. The facial pain and tenderness to the tooth is similar.
If pt has heat sensitivity almost always periapical -> nerve is being affected (pulp)
Tooth gets pushed up out of occlusion (just a few mm) that’s why it hurt to eat and tap on
Pulpitis- decay, bad root canal,
Radiographic analysis shows a round radiolucency at the apex of the tooth. This can be called a periapical abscess.
Etiology:
caries, traumatic fracture of the tooth , or the trauma of a dental procedure.

Drainage of the abscess is similar to the perio abscess.

Microorganisms colonize the pulp, produce toxins, cause pulp cell death and the bacteria and their products exit the apical foramen of the tooth causing localized apical abscess formation
tx: root canal therapy (RCT) (Taking out the nerve, fill with material, pt should not have pain, discolor, easier to break)

94
Q

comparing periodontal and endodontic abscess

A

Periodontal:
type of pain- constant, localized, severe, sharp
vitalitly- vital
Radio image- bone loss but no apical lesion
Endodontic
type of pain- intermittent (comes and goes), hard to localized, extremely severe
vitalitly- usually nonvital
Radio image- apical radiolucency common

95
Q

combined perio-endo lesion

A

Infection spread from the pulp to the periodontium or vice versa.
Difficult to determine what caused what. Symptoms are similar to individual abscesses.
Radiographs shows both bone loss and a periapical lesion.
Treatment involves treating the endo lesion first with a RCT and then treat the perio.
Usually has a crack in root
Don’t know what causes what
Endo first then perio
This is common

96
Q

Peri-implant mucositis

A

inflammation around implant without bone loss
A hole is put into alveolar bone, they can get infected.
don’t probe implants because can damage the seal around the implant
No bone loss
Just imflammation

Q

systemic antibiotics

A

-slow down periodontal disease
AA
Inhibit collagenase activity
Tetracycline
doxycycline
-Metronidazole or flagyl (no AA, generalized aggressive)
- Penicillin/ amoxicillin (still may be effective against periodontal pathogens, but less effective than in the past due to resistance of bacteria against it.)
-Augmentin (amoxicillin and clavulanic acid) shown to be very effective in refractory periodontitis cases
-Clindamycin and ciprofloxacin useful against more aggressive types of perio disease including refractory and generalized aggressive case type diseases
-Synergistic effect
-Amoxicillin and metronidazole in combination have also been shown to effective in Localized aggressive periodontitis (JP) and against A.A.

(Perio chart)
102
Q

When assessing pt what order should you think of

A

Gather information, a complete picture of what is causing the periodontal problem, write up a treatment plan

103
Q

MEDICAL:
What is the purpose of taking a medical history?
Taking of vital signs are important because?

A

base line of information. safety treat the pt. correction with perio and debates, smoking, HIV/AIDS, preg. Medical clearance (infection endocarditis, Coumadin because it is a blood thinner, renal disease -> dialysis and a port.
checking blood pressure, pulse and respiration

104
Q

Dental history:

A

If the pt comes in with a chief complaint (why the pt comes in) you deal with that first!!! When it is not pain deal with other concerns (like a pt with perio that wants white teeth)

gathering any information to help with assessment and treatment

105
Q

Clinical exams include

A 
Extra oral
Intra oral
Oral mucosa
Oral hygiene
Periodontal and dental assessments, including pocket depth , width of attached tissue, recession, mobility, suppuration, plaque and calculus presence, color, size, shape, texture, consistency
106
Q

Contributing factors of bone loss

A
  • calculus
  • over hang
  • food impacted
107
Q

over hang

A

not in line with the root surface (hard to floss, can’t floss, food gets caught) this is a contributing factor to get bone loss

108
Q

Types of staining

A

Bacterial and calculus staining
Brown staining called Tannin staining- found in coffee, tea, fruits and wines; can denature proteins of the pellicle
Chlorhexidine staining
Black staining caused by chromogenic bacteria causing black pigmentation
Green staining- stained remnants of the enamel cuticle in children
The difference between intrinsic and extrinsic staining

109
Q

peridontal assessment

A

-signs/symptoms
-inflammation (first clinical signs would be papillary/marginal)
-destruction of periodontal tissues
- signs of disease (BOP (active), bone loss, odor (active, perio breath, because bacteria living and dying in pockets)
past perio

111
Q

edematms

A

inflammation (edema)

112
Q

Probing

A

The periodontal pocket depth is the measured distance between the gingival margin and the base of the gingival sulcus
Line angle to line angle (middle reading)
Parallel to the tooth (in the same plane)
Walking stroke
PCP UNC – up to 12 mm
Williams – 10 mm

113
Q

Probing

A

The periodontal pocket depth is the measured distance between the gingival margin and the base of the gingival sulcus
Line angle to line angle (middle reading)
Parallel to the tooth (in the same plane)
Walking stroke
PCP UNC – up to 12 mm
Williams – 10 mm

114
Q

Recession

A

Free gingival margin in relationship to the cementoenamel junction (CEJ).

The FGM can be at or slightly coronal to the CEJ,
The FGM can be significantly coronal to the CEJ,
The FGM is apical to the CEJ. Recession

When the FGM is apical to the CEJ resulting in exposure of a portion of the root surface this is termed gingival recession
CEJ to GM
It occurs from mechanical trauma, ortho, particle (clasps)
Connective tissue had been loss – recession
Some times the scaling can cause recession because the inflammation of the gingiva will decrease when the calculus is removed
Root sensitivity
Frenum too high – pulls on tissue causing recession (frenum pull)
Dentinal tubules exposed – sensitive to air
Age- there might be some recession due to the aging process because of how long they have been brushing their teeth.
“long in the tooth” – teeth look long because they have recession
Chewing tabacco
Generalized recession: after ortho (because the teeth have to be moved in the bone)

115
Q

CAL

A

Add inflammation
Subtract recession
It is an estiment – the stability of the JE
If it is moving apically there is disease activity
Probe reading might be CAL if the gingival tissue is where it should be
If the gingival tissue is higher (inflamed) than where it should be then you subtract
Add recession to the pocket depth

116
Q

Bleeding

A

Presence of bleeding has been shown to be an indicator of disease progression

Bleeding = plaque formation

Suppuration can be detected with a probe or by gentle pressure expressing pus from the pocket
active disease

117
Q

Suppuration

A

pus (purulent)

118
Q

tooth mobility

A

All teeth have a slight mobility
Pathologic mobility should be noted

The more severe the bone loss, generally the more mobile
Mobility is measured with the handles of 2 metal instruments placed on each side of the tooth and gently rocked back and forth
3 mobility poor prognosis
Gently rock it back and forth – this will make it easier
2 got trouble, 3 really bad trouble

119
Q

Mucogingival involvement or defect

A

discrepancy in the relationship between the free gingival margin and the mucogingival junction
Common conditions may be the result of:
gingival recession, resulting in inadequate or diminished attached gingiva
Probing depths extending to or beyond the mucogingival junctions into the alveolar mucosa
Anatomical variations that complicate the management of these conditions, including a high frenum attachment pulling the gingival margin away from the tooth
Most common problem with mucogingival involvement: once infection gets past JE the infection becomes more diffuse

120
Q

Calculating the width of attached gingiva

A

BOARDS!
Will the tooth and the bone support a restoration (bridge, proclant fused to metal crown)
Subtract MGJ and PD
By dentist for restortative

A

Usually accompanied by mobility and rotation of the teeth.

Caused by occlusal forces against a weakened periodontium.

Teeth have to be pushed out of the way to move, they do not move on their own.

teeth have already been weaken by perio

129

3-D Imaging: 3 dimensional CT scans: greater detail and accurate measurements
Bony changes; we know where health is, 1-2mm apical to CEJ

137
Q

lamina dura

A

bundle bone that lies adjacent to the periodontal ligament, lining the tooth socket. The lamina dura surrounds the tooth socket and provides the attachment surface with which the Sharpey’s fibers of the periodontal ligament perforate. On an x-ray a lamina dura will appear as a radiopaque line surrounding the tooth root. An intact lamina dura is seen as a sign of healthy periodontium.
