recession and dentine hypersensitivity Flashcards
To enable the student to understand the aetiology, diagnosis and management of gingival recession and dentine hypersensitivity. Define gingival recession and dentine hypersensitivity Describe prevalence and aetiology Understand the possible consequences of recession including dentine hypersensitivity
what is the definition of gingival recession
Gingival margin positioned apical to the cej with exposure of the root surface
what is the prevalence of gingival recession 1mm or more in people aged 30+
58%
what happens to prevalence and extent of recession with age
increases
what is the prevalence and extent in 30-39 year olds
37.8%
and extent of 8.6%
what is the prevalence and extent in 80-90 year olds
90.4
and extent of 56.3%
what is the distribution of recession
maxillary 6s
and mandibular central incisors
which teeth can suffer from dentine hypersensitivity
upper and lower canine
1st premolar and incisor teeth
where can there be greater gingival recession
left side of the jaw
in males vs females
and afrocarribeans rather than caucasians
where is good OHI associated
with buccal surfaces
and where is poor OHI associated
with lingual surfaces of lower anterior teeth
what is the aetiology of gingival recession
periodontal disease OR
normal sulcus and undisposed interdental crystal bone
which teeth are more likely to have gingival recession
teeth near the buccal surface
how else can we have crestal bone loss
by orthodontic movement-
what can orthodontic tooth movement cause
dehiscence
greater risk of recession with XS proclination of lower incisors and arch expansion
what is recession based on
the volume of soft tissue surrounding the tooth
when is there a greater risk of recession-regarding orthodontics
when XS proclination of lower incisors and arch expansion
give examples of trauma
foreign objects- lip/tongue piercing nail biting hard tooth brushing poorly designed dentures- maintained trauma from malocclusion chemical trauma- cocaine
what is tissue called when its bound to the bone
mucoperiosteum
what features of the mucogingival junction can make it more prone to recession
thin and less volume of the tissue can make it more likely to recess
what is the local plaque retention factors
high muscle attachment
frenal pull
what procedure can we do to increase the volume of tissue
gum graft surgery
what can also occur post treatment
recession- need to warn patients sometimes
why does smoking have an effect on recession
once the smoke is taken in it pools behind the upper anterior teeth- direct effect on tissues
what are the consequences of recession
tooth loss bleeding gums plaque retention root caries aesthetics abrasion dentine hypersensitivity
what is dentine hypersensitivity characterised by
short sharp-pain arising from exposed dentine in response to certain stimuli-which cannot be attributed to any other dental disease or defect
