Attachment loss and probing depth
# A patient has a 5 mm probing depth on the distal of their maxillary second premolar, 2 mm of recession was also charted in that area. What is the attachment loss in that area?
A. 7 mm
B. 10 mm
C. 5 mm
D. 3 mm
The correct answer is A. 7 mm.
Periodontal health is assessed by determining how much attachment a tooth has lost. A healthy periodontium demonstrates a sulcular depth of 1-3 mm.
Recession is the distance from the CEJ to the marginal gingiva.
Probing depth is the distance betweeen the marginal gingiva and the floor of sulcus.
Loss of attachment is measured as the distance of CEJ from the sulcular depth.
So, Loss of Attachment (LOA) = Recession+Probing depth
A mature dental plaque is formed after:
# How many hours after mechanical debridement with a toothbrush is a mature dental plaque found?
A. 24-48 hours
B. 3-5 hours
C. 6-10 hours
D. 12-24 hours
E. 1-2 hours
The correct answer is A. 24-48 hours.
Mature dental plaque is usually formed on the teeth within 24-48 hours after plaque removal.
The bacterial biofilm first attach to the tooth via a pellicle, consisting of glycoproteins.
The first bacteria to attach to the pellicle glycoproteins are gram positive aerobic cocci such as Streptococcus sanguinis.
After 24 hours, anaerobic gram negative cocci, rods, and filaments begin to colonize the plaque.
Artery supplying the buccal flap in an oroantral communication associated with maxillary third molar
# A buccal flap used to cover an oroantral communication associated with maxillary third molar would receive nourishment from which of the following arteries?
A. Posterior superior alveolar
B. Nasopalatine
C. Greater palatine
D. Facial
The buccal flap will receive its nourishment from the blood vessel that supplies the maxillary third molar, which is the posterior superior alveolar artery.
Posterior superior alveolar artery is the blood vessel that provides blood supply to the lining of maxillary sinus, the alveolar bone, the molars and premolars of the maxilla and the gingiva.
Facial artery branches out and supplies blood to several parts of the face which includes the lips, portions of the nose, submental area and some portions of the tonsils.
Nasopalatine artery (sphenopalatine artery) branches off to the walls of nasal septum.
Greater palatine artery gives off blood supply to the nasal septum and the hard palate.
