PROCEDURE:
The same surgeon will be operating on all the patients. The choice of
local anaesthetic for the first operation was randomised (by toss of a
coin) and they were given the other local anesthetic for the second
side.0.5 ml of 0.75% ropivacaine will be infiltrated intradermally as
test solution.. The Numerical rating scale(NRS), visual analog scale
(VAS) and Verbal descriptive scale(VDS) will be explained preoperatively
and patients will be asked to notify as soon as the lip and tongue
becomes numb. Desired area will be then anaesthetised and a standard
surgical technique will be used for implant placement. In all cases, the
incisions were mid-crestal with no vertical releasing incisions, and the
incisions were extended mesially and distally to assure accessibility.
The incisions were extended as needed to expose at least 5 mm of bone.
Vital parameters were monitored and pain score assessment were recorded
before injecting the drugs, on injecting and same parameters were
recorded after injection at intervals of 30 minutes,1,3,6,9 hours on the
day of surgery(D1),first (D2) and second day after surgery(D3).
All the patients were assessed for level of comfort and depth of
anaesthesia intra-operatively via VAS, VDS, NRS scales immediately after
implant surgery, for both the agents to assess the depth of anesthesia
achieved.
