1 Advantages of GowGates include higher success rate in comparison with IANB, decreased incidence of positive aspiration and increased area of anesthesia.
This randomized single blind clinical trial compared the effectiveness of 4 % articaine BI versus IANB in symptomatic mandibular 1stmolar.
Group 1 consisted of subjects who received a standard IANB of 4% Articaine with 1:100,000 epinephrine using 27 gauge 0.
Buccal infiltration with 4% articaine is equally effective as articaine IANB in anaesthetising mandibular molars with irreversible pulpitis [Poorni et al.
Many groups of patients may benefit from being able to avoid IANB for dental treatment, including children with special health care needs.
The main outcome of our study was the successful IANB on cold test at 45 minutes and successful IANB on access cavity.
Anesthesia success has also improved in situations where an IANB with 2 percent lidocaine 1:200,000 epinephrine (Lido200) was supplemented with infiltrations of either Lido200 or 4 percent articaine with 1:200,000 epinephrine (Art200).
Conventional IANB was performed by depositing anesthetic agent of 2ml of 2% lignocaine hydrochloride (Septodent France) and epinephrine 1: 100,000 using 27-gauge disposable needle in pterygomandibular space while retrieving needle lingual nerve block, and after withdrawing needle long buccal nerve blocks were also performed in both groups.
Even though buccal infiltration of 4% articaine and IANB of 2% lidocaine were equally effective, buccal infiltration can be considered a viable substitute in IANB for anesthetizing mandibular first molar with irreversible pulpitis.
The greater suc- cess rate of IANB by the most experienced dentist was not unexpected.
