4% articaine, 1:100,000 epinephrine vs 2% lidocaine, 1:100,000 epinephrine

Duration of anaesthesia (pulpal, electric pulp tester; healthy pulps) · Participants of any age and gender undergoing dental procedures, and volunteers who took part in simulated scenario studies in which…

It is very uncertain whether 4% articaine, 1:100,000 epinephrine changes duration of anaesthesia (pulpal, electric pulp tester; healthy pulps) compared with 2% lidocaine, 1:100,000 epinephrine (very low certainty).

Early extraction of a compromised mandibular first permanent molar vs Contralateral non-extraction side (same patient)

Development and eruption of the third molar · Children aged 5 to 15 years with a compromised first permanent molar

Development and eruption of the third molar appeared accelerated after early first permanent molar extraction in two studies (e.g., eruption OR 2.86, 95% CI 1.37 to 5.96); ungraded.
