Paediatric periodontology Flashcards
What are the aims of 2021 guidelines for Periodontal screening and management of under 18years of age?
- Outline method of screening under 18years for periodontal diseases during routine clinical dental examination in order to detect presence of gingivitis or periodontitis at earliest opportunity
- Provide guidance on periodontal management and when it is appropriate to treat in practice or refer to specialist services, thus optimizing periodontal outcomes for children and young adolescents
What is the Mnemonic to remember the 2017 World Workshop classification for periodontal disease?
Please Give Greg Nine Percy Pigs Straight Past Meal Time Tonight
What are the categories for 2017 World Workshop Classification of periodontal disease?
- Periodontal health (Intact or reduced periodontium)
- Gingivitis - dental biofilm induced (intact or reduced periodontium)
- Gingival diseases and conditions - non dental biofilm induced
- Necrotising periodontal diseases
- Periodontitis
- Periodontitis as a manifestation of systemic disease
- Systemic disease or conditions affecting periodontal supporting tissues
- Periodontal abscesses and endodontic-periodontal lesions
- Mucogingival deformities and conditions
- Traumatic occlusal forces
- Tooth and prosthesis related factors
What is periodontal health?
- A state free from inflammatory periodontal disease
- Allows an individual to function normally
- Avoids physical and mental consequences due to current or past disease
What are features of healthy periodontium in children?
- Gingival margin several mm coronal to cemento-enamel junction
- Gingival sulcus 0.5mm-3mm deep on fully erupted tooth
- In teenagers, alveolar crest situated between 0.4mm-1.9mm apical to CEJ
What can cause reduced periodontium in the 2017 classification?
In a non-periodontal patient
- Crown lengthening surgery
- Recession
In a periodontal patient
- Stable periodontitis
In regard to BPE what is the clinical presentation of periodontal health?
- <10% Bleeding on probing is clinical periodontal health in either intact or reduced periodontium
What are the two types of gingival conditions?
- Plaque biofilm-induced gingivitis with either intact or reduced periodontium
- Non plaque biofilm-induced gingivitis/ gingival lesion
What is plaque biofilm-induced gingivitis?
- Supragingival plaque accumulates on teeth
- Inflammatory cell infiltrate develops in gingival connective tissue
- Junctional epithelium becomes disrupted
- Allows apical migration of plaque and increase in gingival sulcus depth
- Gingival pocket/ false pocket/ pseudo pocket
- Most apical extension of junctional epithelium is still CEJ
- Process is reversible
- No periodontal attachment loss
What can gingival diseases non-dental biofilm induced be?
- Manifestations of systemic conditions
- Pathologic changed limited to gingival tissues
What are the sub-classifications of Gingival diseases: non-dental biofilm induced?
1) Genetic/Developmental disorders
2) Specific infections
3) Inflammatory and immune conditions and lesions
4) Reactive processes
5) Neoplasms
6) Endocrine
7) Nutritional and metabolic diseases
8) Traumatic lesions
9) Gingival pigmentation
What genetic factors can cause gingival diseases and conditions: non-dental biofilm induced?
- Phenotype
- Hereditary fibromatosis (characterised by benign, non-haemorrhage, fibrous gingival overgrowth showing clinically pink gingiva with marked stippling and can prevent eruption)
What Infective factors can cause gingival diseases and conditions: non-dental biofilm induced?
- Viral
- Fungal
- Bacterial
- Deep mycoses (disease caused by fungi)
What Trauma factors can cause gingival diseases and conditions: non-dental biofilm induced?
- Thermal/ chemical
- Physical
What Drug induced factors can cause gingival diseases and conditions: non-dental biofilm induced?
- Immune complex reactions
- Anti-retro-viral
- Immunosuppressants
- Ca+ channel blockers
- Anti- convulsant
- Cytotoxic
What Manifestation of systemic disease factors can cause gingival diseases and conditions: non-dental biofilm induced?
- Granulomatous inflammation
- Immunological conditions
What are features of Necrotising gingivitis?
- Pain
– Necrosis of interdental papillae -“punched out” appearance
– Ulceration
– Spontaneous bleeding
– Secondary foetor oris
– Pseudomembrane may be present
– +/- lymphadenopathy
– Fever
– May manifest in teenagers
– May progress to necrotising periodontitis (NP)
What are risk factors of Necrotising gingivitis?
- Smoking
- Immunosuppression
- Stress
- Malnourishment
- Poor diet
What is the aetiology of Necrotising gingivitis?
- Fusiformspirochaetal microbial aetiology
- Socioeconomic factors esp in developing countries
- Local factors inc root proximity and tooth malposition
- Systemic factors inc HIV positive status
- Underlying undiagnosed pathology in immunosuppressed host
What are the modifying (systemic risk factors) factors for the other conditions affecting the periodontium?
- Smoking tobacco
- Metabolic factors (hyperglycaemia/ Diabetes type 1)
- Pharmacological agents (cyclosporin)
- Nutritional factors (Vit C deficiency)
- Increase in sex steroids (puberty or pregnancy)
- Haematological conditions (Leukaemia)
What are the predisposing (local risk factors) for other conditions affecting periodontium?
Malocclusion
- Instanding or rotating tooth
- Traumatic occlusion: Low frenal attachments
Traumatic dental injury
- Damage to PDL i.e. luxation/ intrusion/ avulsion
Dental plaque-biofilm retentive factors
- Tooth anatomy e.g. talon cusp, cingulum, enamel pearl, enamel defects like pits or grooves
- Restoration margins/ overhangs/ cavities
- Ortho/Prosthodontic appliances
- Incompetent lip seal lead to oral dryness as decrease saliva flow and decrease saliva quality
What is gingival overgrowth related to?
- Systemic and metabolic diseases
- Genetic factors like hereditary gingival fibromatosis
- Local factors
- Side effects by some medications e.g. cyclosporin, phenytoin and calcium channel blockers
