Areas of interest within periodontium where primary and permanent dentitions differ
|
• Papillary gingiva
• Marginal gingiva • Attached gingiva • Alveolar mucosa • Alveolar bone • Periodontal membrane |
|
primary VS permanent
Papillary gingiva |
Interdental saddle
|
|
primary VS permanent
Marginal gingiva |
– Deeper sulcus
– Thicker, rounder free gingival margin |
|
primary VS permanent
Attached gingiva |
– Thinner, less keratinised
– Greater vascular – Less connective tissue, less dense – Less stippled (dev 2-3 y-o) – Less width |
|
primary VS permanent
• Alveolar mucosa |
Redder since thinner epithelium
– Less keratinised, more vascular |
|
primary VS permanent
Alveolar bone |
Less calcified, more vascular, larger marrow space
Flatter interdental crest |
|
primary VS permanent
Periodontal membrane |
Wider periodontal space and less dense
since fewer fibers/unit area |
|
Influence of permanent tooth eruption
Active stage? |
Occurs until contact with antagonist
– Reduced epithelium |
|
Influence of permanent tooth eruption
Passive stage |
– Occurs when sulcular epithelium
changes after occlusion – Occurs over 10 years period – Increase crown length, decrease sulcular depth – Stabilise between 16-18 years of age |
|
Clinical appearance of gingivitis?
|
Reddish and swollen marginal gingiva
– Interdental papillae protruding – Bleeding tendency |
|
Puberty Gingivitis
Causes? |
•Hormonal changes esp female
adolescents |
|
Puberty Gingivitis
when does it subside? |
when hormonal changes end
approx 18 y-o |
|
Puberty gingivitis
Treatment? |
•Regular scaling
•Oral hygiene measure |
|
Modifying factors of periodontitis?
|
Calculus
Defective restorations Caries Systemic diseases |
|
Systemic diseases that are modifying factors of periodontitis?
|
– Diabetes mellitus
– Hypophosphatasia – Histiocytosis-X – Papillon-Lefevre syndrome |
|
Types of Periodontitis in children?
|
Prepubertal
Juvenile |
|
What are the characteristics of prepubertal periodontitis?
|
• Immediately after eruption of primary teeth
• Prevalence is <0.5%, ethnic difference • Hereditary pattern in some cases |
|
What are the types of prepubertal periodontitis?
|
localised and generalised
|
|
Prepubertal periodontitis :
– Localized form :? |
Some primary teeth affected
Mild to moderate inflammation Slow destruction Healthy individual No previous infection Response to antibiotics |
|
Prepubertal periodontitis
– Generalized form? |
Severe/ all primary teeth involved
Severe sign of inflammation May lead to premature loss of teeth Previous infections No response to antibiotics Often associated with systemic conditions Should be referred for medical examination |
|
Features of Juvenile periodontitis
|
• Early permanent dentition
• Male > female • Rapid progressing, rapid bone loss • Often preceded by bone loss in primary dentition • Two forms – Localised – Generalised |
|
Juvenile periodontitis :
– Localized form |
» Moderate signs of inflammation
» Involved 2 or more teeth » Usually first molars and incisors |
|
• Juvenile periodontitis :
– Generalized form |
» Severe signs of inflammation
» Involved 8 or more teeth |
|
Periodontitis
Treatment |
– Scaling and root planning, debridement
– Preventive program to reduce plaque accumulation – Extraction of severely affected primary teeth – Recall – Referral |
|
White lesions and infections
|
Inclusion cysts (gingival cyst of infants)
Geographic tongue |
|
Inclusion cysts?
|
– One or multiple freely mobile nodular white lesions
– Small superficial keratin-containing cysts – Asymptomatic, exfoliated spontaneously |
|
Geographic tongue?
|
(migratory glossitis)
– Migratory desquamative area on dorsal, lateral of tongue – Erosion or loss of papillae – Appears to have white and red lesions – No treatment – May host other dermatologic conditions |
|
Ulcerative lesions?
|
• Aphthous ulcers
• Traumatic ulcer |
|
Compressible lesions
|
• Eruption cyst
• Hemorrhagic cyst • Gingival parulis • Mucous retention cyst |
|
Types of Mucous retention cyst
|
ranula
mucocele |
|
Nonhemorrhagic soft tissue lesions
|
Congenital epulis
|
|
Congenital epulis?
|
– Unknown aetiology
– Single, elevated, smooth – Benign tumour – Maxilla – Rare in mandible – Surgery – Low recurrent |
|
Vesticular-desquamative lesions and infections
|
• Herpetic gingivo stomatitis
• Herpes labialis • Vericella ulcer (chickenpox) Vesticular-desquamative lesions and infections • Herpes zoster • Herpangina • Hand Foot Mouth disease |
|
Explain herpes simplex virus infection in children, especially aetiology, clinical features (signs and symptoms), and management.
|
Infection by HSV1 in children with peak age of 0 - 2. Incubation period 4-5days. Fever 1-2days, acute vesicles 3-7days followed by ulceration 10-14days. Managed with Antivirals, fluid maintenance, supportive, symptomatic treatments
