COMPLETE SOLUTIONS (A+)
xray benefits
- DETECT DISEASE
- minimize & prevent toothaches, surgery
- saves time & money, prevents edentulismlosing all teeth
xray use
- DETECT diseases, lesions, trauma, foreign objects
- bone levels deteriorating, evaluate growth & developement
what can be found xray
missing teeth
- may lead to occlusion problems as a result of drifting or tipping
- orthodontic treatment in the absence of teeth can prevent occlusion problems
- conditions: hereditary ectodermal dysplasia, books syndrome, riegers syndrome*
radiograph
aka radiogram
a picture that is, a visible photographic record on a film produced by the passage of
x-rays through an object or body
- can ONLY be prescribed by DENTISTS
- should never be routine/predetermined
,MEDSTUDY.COM
impacted/embedded teeth
- MOST COMMON development defects
- should be removed surgerically to prevent odontogenic cyst formation, damage of
adjacent teeth and bone resorption which may lead to fractions
impacted tooth
- one tooth is PREVENTED FROM ERUPTING due being wedged up against a
neighbouring tooth
- ALWAYS necessary to extract
- most common: third molars, premolars, max cuspid (canine), supernumerary
embedded tooth
- if a tooth is not breaking though the gum because of being UNDER BONE
- tooth is being blocked by the gum it may lack the force necessary to break thru the
gum
dental caries
- bitewings for interproximal various lesions
- pulse of tooth dies
- if left untreated, can result in destruction of a large amount of tooth structure and pulp
all necrosis
- decay may recur under the margins of existing restorations and may or may not be
seen clinically
- black circular areas on xray
- rampant dental caries, recurrent decay, early root caries
rampant dental caries
,MEDSTUDY.COM
recurrent decay
early root caries
periodontal disease
- disease of the BONE
- CANNOT be diagnosed wo xray
- xrays enable to identify predisposing factors (calculus faulty restorations, bony
changes including furcation involvement)
- provide baseline info concerning periodontist, can be used as pretreatment reference
source
furcation involvement
- generally seen in MOLARS
- bone has come down, created a SPACE/HOLE between the bone and gums
dilacerated roots
- SHARP BEND of the roots or a sharp bend bw the crown and root
- caused by some traumatic episode during tooth formation
- produces CHALLENGES IF EXTRACTION IS NECESSARY
retained root tips
- root tips or fragments are sometimes left behind following a complicated tooth
extraction
- retained root tips are usually asympomatic
- ONLY discovered by xrays
- usually dont require extraction, should PERIODICALLY be re-evaluted
, MEDSTUDY.COM
periapical lesions
- the MOST COMMON radiographic appearance of a periapical lesion is the
RADIOLUCENCY (dark) area at root apex
- a diagnosis of periodical cyst, granuloma or abcesses cant be made based on xray
findings alone
other lesions
- numerous dental anomalies, cysts, tumours & diseases affect the jaws
- lesions may persist for years before signs & symptoms develop
- xray play VITAL role in the detection
- the importance of EARLY detection & diagnosis cannot be OVERSTATED
interpretation
- ablity to read whats revealed by an xray
- an EXPLANATION of what's viewed
- dental hygienist prepares a preliminary interpretation & presents the findings to
dentist
- dh must be confident w the identification (normal anatomy, caries, disease, traumatic
injuries, lesions.)
diagnosis
- dh is RESTRICTED by law from rendering a diagnosis
- "TO KNOW", "to DISTINGUISH"
disclosure
- the process of informing the the pt about the particulars of exposing dental xrays
- easy language,
- explain: value & purpose, the client exam: limtiation wo xray
documentation
