Oral SurgeryIncrease the rate of liver metabolism of local anesthetic: Alpha adrenergic agonists, such as epinephrine, are often added to local anesthetics to enhance their effectiveness. They achieve this by causing vasoconstriction at the injection site, which reduces bleeding and increases the duration of anesthesia. However, they do not directly increase the concentration of LA at the receptor site or alter liver metabolism. Therefore, the correct answer is 2) Increase the concentration of LA at receptor site.

OrthodonticsSOLUTION
The possibility that a distal step would become class II is very real, and this not self correcting problem. When the central incisors erupt, these teeth use up essentially all of the excess space in the normal primary dentition. With the eruption of the lateral incisors, space becomes tight in both arches.
Normal child will go through a transitory stage of mandibular incisor crowding at age 8 to 9 even if there will eventually be enough room to accommodate all the permanent teeth in good alignment. In other words, a period when the mandibular incisors are slightly crowded is a normal developmental stage.
Continued development of the arches improves the spacing situation, and by the time the canine teeth erupt, space is once again adequate.

Gingival group of fibers
Principal fibers of the periodontal ligament rearranges themselves quite rapidly to the position in about 4 weeks.The supra-alveolar gingival fiber take as much as 40 weeks to rearrange around the new position and thus predispose to relapse.

General MedicineThe sudden onset of symptoms, along with neck stiffness and photophobia, suggests meningitis. The CSF findings of a high white blood cell count with a predominance of neutrophils and low glucose are more indicative of bacterial meningitis, as this pattern is less common in viral or fungal meningitis.
