    • Dental Caries ! Ryan Bukhari
    • Over View • Definition. • Causes. • Mechanism. • Classification. • Prevention. • Diagnosis. • Treatment. • Conclusion.
    • What is Dental Caries? • Definition. • Destructive process. • What could happen if it is not treated? • pain, infection… • How does it look like? • Small chalky area –>large brown cavitation.
    • Causes Carbohydrates Tooth surface Bacteria Time
    • Mechanism Metabolism Acid Drop in pH Demineralization Cavitation
    • Classification Dental Caries Location Rate of Progression Black Pit & Fissure Caries Smooth Surface Caries Acute Incipient Chronic Recurrent Caries Class I Class II Class VI Class III Class IV Class V
    • Pit & Fissure Caries • What are pits and fissures? – Anatomical landmark on a tooth. • What is the pattern of the decay? – Two triangles with conjoined bases.
    • Smooth-Surface Caries Three types of smooth-surface caries: I. Proximal (inter-proximal) caries. II. Root caries. III. The third type. This radiograph shows proximal caries.
    • Rate of Progression • Acute. (fast with pain) • Chronic. (slow without pain) • Recurrent caries. (with previous history) • Incipient. (without previous history)
    • Black Classification System Black classification is based on the required treatment. • Class I. (occlusal). • Class II. (posterior proximal). • Class III. (anterior proximal). • Class IV. (incisal). • Class V. (cervical). • Class VI. (caries in cusps)
    • Prevention • Personal oral hygiene care. – Brushing, flossing & using mouth rinses. • Professional oral hygiene care. – Regularly dental examination.
    • Other Preventive Approach • Minimizing snacks. • Dairy products. • Chewing sugar free gum. • Fissure sealant. • Application of fluoride.
    • Diagnosis • The primary diagnosis. – Light, dental mirror & explorer. • Dental radiographs.
    • Treatment • Small caries. (reminerlize lost structure) • Large caries. (prevent further destruction) Trays used for applying fluoride
    • Treatment • Dental filling • Crowns • RCT • Extraction
    • Conclusion • Dental caries is considered as one of the diseases of the human body which should be treated. ! • Frequent dental visit for routine dental check up help prevent dental caries.
