Due to anatomy a premolar bitewing radiograph will almost always exhibit overlap between the
A) distal of the lateral incisor and the mesial of the canine.
B) distal of the canine and the mesial of the first premolar.
C) distal of the first premolar and mesial of the second premolar.
D) distal of the second premolar and mesial of the first molar.
B
Explanation: A) The canine periapical and bitewing radiographs will almost always exhibit overlap between the distal of the canine and the mesial of the premolar. This overlap occurs because the curve of the arches in this region superimposes the lingual cusp of the premolar onto the distal edge of the canine.
B) The canine periapical and bitewing radiographs will almost always exhibit overlap between the distal of the canine and the mesial of the premolar. This overlap occurs because the curve of the arches in this region superimposes the lingual cusp of the premolar onto the distal edge of the canine.

If the urine culture demonstrates bacterial growth, how will the microbiology laboratory define a urinary tract infection for this individual? A) A pooled 24 clean catch voided urine with >100,000 CFU/mL of one bacterial species B) A single catheterized urine with >103 CFU/mL of one bacterial species C) Two consecutive clean catch voided urines with >100,000 CFU/mL of one bacterial species D) A single clean catch voided urine with >105 organisms/mL of one bacterial species
Why do providers often request a clean-catch midstream urine specimen?
