Phrosdothotics Flashcards
Why can fail a veneer
- inappropriate preparation design,
- inadequate occlusal thickness,
- sharp line angle,
- rough margins
we can do if the patient has thrombocytopenia
- Non-invasive dental procedures can be performed if the platelet count is 30,000/µL or higher.
- Extractions and minor surgery can be performed if the platelet count is 50,000/µL or higher.
- Major oral surgery can be performed if the platelet count is 80,000/µL to 100,000/µL or higher
safiest antibiotics
,amoxicillin and cephalexin (a cephalosporin antibiotic) are considered the safest antibiotics to prescribe to patients taking digoxin
what is it Midazolam
Midazolam is a benzodiazepine commonly used to achieve IV conscious sedation
fentanyl
Fentanyl is a highly potent synthetic opioid that is commonly used as an adjunct to IV conscious sedation,
properties of salivary
Saliva has anti-cariogenic properties through buffering, remineralizing, and cleansing.
s cleidocranial dysplasia.
- short stature,
- defective or missing clavicles,
- distinct facial features.
- supernumerary teeth.
Ectodermal dysplasia
genetic disorders that involve abnormalities in the structures derived from the ectodermal layer of the embryo during development (hair, skin, nails, and sweat glands).
abnormalities in the teeth such as hypodontia and conical-shaped crowns.
Failure during the bud stage
The bud stage of one of the first stages of tooth development
early tooth structure forms from the dental lamina.
Defects congenitally missing teeth or hypodontia.
down syndrome
flattened facial profile, delayed tooth eruption, macroglossia, and hypodontia.
Complex odontoma
benign odontogenic tumor associated with unerupted teeth
contains a conglomerate mass of enamel and dentin that bears no anatomic resemblance to a tooth.
It would manifest as a radiopaque finding. detected in the second or third decade of life and occur
most commonly in the posterior mandible
CEOT
A calcifying epithelial odontogenic tumor (CEOT) (i.e., Pindborg tumor) is a benign odontogenic neoplasm
to arise from remnants of the dental lamina.
They are associated with unerupted or impacted vital teeth
Posterior mandible as a painless, expansile, slow-growing mass.
Radiographically, they appear as mixed lesions with septa.
Pulp canal obliteration
Pulp canal obliteration calcific metamorphosis) describes an apparent loss of the pulp chamber and obliteration of the canal space on a radiograph. Clinically, teeth with pulp canal obliteration are often discolored and lack incisal translucency. Traumatic injuries often cause this.
Teeth with pulp canal obliteration have unreliable results to sensibility tests and can have a decreased response to cold despite having vital pulp.
Cross-sectional studies and longitudinal studies
Cross-sectional studies and longitudinal studies are research studies in which an environment .
In cross-sectional studies, observational data is collected from a population at a specific point in time.
In longitudinal studies, data is collected from the same sample over a period of time.
both studies examine a variable (e.g., age, gender, income) and measure its association with an outcome (e.g., blood pressure measurement, cholesterol levels).
diabetic ketoacedosis
Diabetic ketoacidosis is a potentially life-threatening complication that may develop in patients with uncontrolled type 2 diabetes mellitus
diabetes is also associated with dysgeusia (i.e., taste disorder), increased risk of periodontitis, and xerostomia
calculus
The appearance of calculus varies based on its location. Subgingival calculus typically appears dark brown or black and is mineralized by the gingival crevicular fluid. It is dense in consistency. Supragingival calculus typically appears white or yellow and is mineralized by the mineral salts in the saliva. It is clay-like in consistency.
Lymphocytes
T cells, B cells, natural killer cells are involved in the targeted immune response and play a significant role in chronic inflammation. Therefore, they arrive later at the wound site.
Monocytes
large phagocytic cells that help clean up debris and dead cells, promote tissue repair, and regulate the immune response. They arrive at the wound site after neutrophils.
Plasma cells
activated B cells during the adaptive immune response. They produce antibodies and do not arrive at the site of the wound.
Periapical granuloma
proliferation of granulation tissue containing inflammatory infiltrate at the apex of a necrotic tooth.
This is a chronic lesion and usually does not result in pain.
Although both periapical abscesses and granulomas appear on a radiograph as apical radiolucencies, neutrophils are not predominant in periapical granulomas.
Periapical scar
appears on a radiograph as a well-defined periapical radiolucency found after endodontic treatments and re-treatments. These lesions have dense fibrous collagenous tissue and are asymptomatic.
