introduction to operative dentistry Flashcards
operative dentistry deals with the____
art and science of dealing with the prevention , restoration/ defect and prognosis of disease in hard tooth structure
Is the art and science of the diagnosis, treatment and prognosis of the defects of teeth that do not require full coverage restorations for correction.
what are the procedures done to prevent any recurrence of disease and their defects ?
-location of the margins
-shape/contour of final restorations
-sealing of enamel faults (pits and fissures)
what procedures are done with the goal of interception :
-change in patients home care habits
-removal of the lesion
-correction of occlusion (crowded and misaligned teeth tend to be more susceptible to caries)
restoration in operative dentistry is aimed not only at teeth but also at the ____
surrounding supporting tissues and to the entire stomatognathic system
pit and figure carries can occur where?
-occlusal surface of posterior teeth
-buccal or lingual surface of posterior teeth
-lingual fossa of maxillary incisors
what’s the difference between primary and secondary caries?
primary caries is the very first time a tooth is attacked by caries (extent or surface doesn’t matter it could be any )
secondary caries are recurrent caries that develop at the margins or beneath existing restorations
appearance of inactive lesions :
-usually brown or black spots
acute vs chronic caries:
acute caries progressive’s rapidly towards pulp and have a light soft appearance
chronic caries progress slowly towards the pulp and have a dark and hard appearance
what are rampant caries ?
multiple active carious lesions involving surfaces of teeth that are usually caries free
what are incipient caries?
caries that are confined to enamel and do not penetrate the DEJ
what are advanced caries ?
the lesions that penetrate the DEJ into the dentin
what are the causes of non-carious tooth loss , explain each.
attrition (wear from opposing teeth. caused by age , bruxism and clenching )
abrasion (loss of tooth material by wear other than the contacting surfaces)–commonly occurs as dish shaped or Shaped lesions buccally at cervical margin –caused by vigorous brushing , abrasive tooth paste
erosion (loss of dental hard structure as a result of a chemical process not involving bacteria)–commonly occurs on palatal surface in anterior teeth , buccal surface in posterior teeth
where is abrasion mostly seen?
dish shaped or V-shaped lesions buccally at cervical margin caused by vigorous brushing or abrasive tooth paste
what surfaces are mostly affected by erosion ?
lingual surface of anterior teeth and buccal surface of posterior teeth
fluorosis is an example of___ staining
intrinsic
