other conditions: periodontitis

Question 1

types of abcess

Answer 1

periodontal: accumulation of advance gum disease
periapical: untreated dental caries, cracks and trauma
gingiva: trapped food or foreign body between the tooth and gum
pericoronal: within the gingiva that covers a partial erupted or impacted tooth

Question 2

what is the cause of periodontal abcess?

Answer 2

bacteria accumulation or foreign body impaction in periodontal pockets

Question 3

what is endodontic?

Answer 3

is a pathological communication between the pulpal and periodontal tissue at a given tooth that may occur in acute or a chronic form

Question 4

mucogingival deformities and conditions around teeth

Answer 4

periodontal biotype
gingival/soft tissue recession
lack of keratinised gingiva
decreased vestibular depth
aberrant frenum/muscle position
gingival access
abnormal color

Question 5

what is frenum attachment?

Answer 5

a thin fold of mucous membrane with enclosed muscle fibres attach the lips to the alveolar mucosa and periosteum

Question 6

non - carious cervical lesions

Answer 6

recession of gingiva - any loss hard tissue in the enamel junction but not caries

Question 7

define the occlusal trauma

Answer 7

creates zones of tension and pressure in the periodontium. thickening of the lamina dura, width of PDL space increase - increase diffuse periodontal bone density and vertical bone loss

Question 8

list clinical and radiographic indicators of occlusal trauma

Answer 8

fremitus, mobility, tooth migration, fractured tooth, thermal sensitivity, discomfort/pain on chewing, widened PDL space, root resorption, cemental tear, occlusal dicrepancies

Question 9

tooth and prostheses related factors

Answer 9

biologic width,
fixed dental restorations, dental materials, removable dental prostheses, enamel pearls, cervical enamel projections, developmental grooves, tooth and root fractures, root resorption, tooth position, root proximity, open contacts
