CDS Perio Flashcards
What are the SDCEP ideal outcomes of periodontal treatment?
Plaque scores below 15%
Bleeding scores below 10%
Probing depths 4mm or less and no bleeding at 4mm sites
What symptoms is a patient likely to have at periodontal review?
Sensitivity - tissue has shrunk because of reduced inflammation
Patients should be warned of this before step 2
How should post treatment sensitivity be handled in perio patients?
Reassurance
High fluoride toothpaste
Non responding site
A site where deep probing depths remain and have not improved (>4mm or 4mm with bleeding) after supra and subgingival instrumentation
Possible mechanisms for smoking increasing periodontal disease
- Systemically compromising the innate and adaptive immune response
- Topical reduced tissue vascularity influencing any subsequent wound healing of the affected tissues
Clinical outcomes of gingival recession
Dentine hypersensitivity
Aesthetic concerns
Plaque retention and inflammation
Tooth abrasion
Root caries
Step 1 perio treatment
Addressing risk factors
Plaque control
Supragingival scaling
Step 2 periodontal treatment
Subgingival scaling
What must all patients be warned of before commencing perio treatment?
Risk of gingival recession
Can cause aesthetic concerns, sensitivity
Predisposing factor to aesthetic concerns with gingival recession
High smile line
TIPPS
Talk
Instruct
Practice
Plan
Support
How long after step 2 treatment do you re-evaluate and why wait?
8-12 weeks
To allow healing
What else must be done if using systemic antibiotics in perio and why?
Mechanical biofilm disruption
The biofilm will have ~500 species of microbe embedded in a matrix, protecting them from antimicrobials, once this is done the bacteria in the mouth will be disorganised, then when hit with antibiotics it will be effective
Which group of people can have increased BOP with improvement in pocket depths?
Previous smokers who have quit
How might a periodontal emergency present?
Pain
Swelling
Tooth mobility
Bleeding
Pus discharge
Lymphadenopathy
Ulceration
Why is the HPC/pain history important when a periodontal emergency presents?
To help determine whether the pain is due to a pulpal cause or periodontal cause
Periodontal emergency
When an acute condition involving the periodontium causes pain, forcing the patient to seek urgent care, usually with GDP as the first port of call
May involve pain, swelling, tooth mobility, bleeding, suppuration, lymphadenopathy, ulceration
Why is timely management of periodontal emergencies necessary?
To prevent further damage to the periodontium, as well as improving the patient’s physical and psychological wellbeing, and prevent spread of infection
3 important considerations in treatment of a periodontal emergency
Partially erupted and impacted mandibular third molar
Nail biting habit - foreign body can cause gingival abscess
HPC/ pain history - try to determine whether pulpal or soft tissue origin
Investigations for periodontal emergency
- Radiographs to check whether periodontal patient
- Sensibility testing - is pulp involved
- TTP
- Clinical exam - hard or soft, is there a pocket, where is the lesion, is tooth heavily restored
Typical appearance of an endo-perio lesion radiographically
J shaped lesion
Grades of endo-perio lesions
1 - narrow deep perio pocket in one tooth surface
2 - Wide perio pocket in one tooth surface
3 - Deep perio pockets in more than one tooth surface
What must you include in an endo-perio lesion diagnosis?
Whether it is a periodontal patient or not, whether there is root damage and what, and a grade
What is the diagnosis and why
Endo perio lesion (J shape)
in periodontitis patient (bone loss) with no root damage, grade 3 (deep perio pocket affecting more than one surface)
Treatment options for endo-perio lesion
Extirpate the pulp or XLA
Debride the pocket to drain pus
Antibiotics if systemic symptoms - pen V 500mg 4x daily 4 days or if allergic 400mg metronidazole 3x daily 5 days
Recommend 0.2% chlorhexidine 10ml 2x daily one minute or 6% H2O2 for 2 minutes
What is the difference between pericoronitis and a peri-coronal abscess?
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth
A peri-coronal abscess is the localised accumulation of pus within the overlying gingival flap surrounding the crown of an incompletely erupted tooth
