Extraction of maxillary teeth by dental students without palatal infiltration of local anesthesia: A
randomized controlled trial
Sara Rahim Khan
CMH Lahore Medical and Dental College, Pakistan
Aim: Palatal infiltration of local anesthesia (LA) for maxillary tooth extractions is painful. One of the techniques for reducing the
discomfort of this injection is to avoid it altogether. Given enough time, LA given only as buccal infiltration diffuses to reach and
anaesthetize the palatal tissues. The aim of this double blind randomized controlled trial was to test the hypothesis that LA infiltrated
by dental students only into the buccal tissues should be adequate for maxillary tooth extraction.
Patients &Methods: 50 adult patients presenting for single tooth maxillary extractions were randomly allocated between two groups.
The control group received palatal injections of 0.1ml 2% lidocaine with 1:100,000 epinephrine, while the experimental group received
a similar amount of saline (placebo). Extractions performed without further administration of LA were categorized as successful.
Results: Palatal infiltration of lidocaine with epinephrine was significantly more effective than saline (p=0.002). Overall buccal
infiltration alone was successful in 28% patients with a 40% success rate in the posterior maxilla.
Conclusion: Results suggest that dental students should, as a matter of routine, extract maxillary teeth with both buccal and palatal
infiltration of LA, while buccal infiltration by itself may be considered in selected cases for the posterior maxilla.
Call for participation: Clear aligners for outpatients with severe malalignment
Hosamuddin Hamza
K Line International, Egypt
Objectives: To widespread the use of clear aligners to include cases with severe malalignment, to develop new engagers system that is
applicable by patients and does not necessitate several visits to dental clinic, to help outpatients to achieve optimal benefit from clear
aligner therapy with minimal office recalls and to implement new material in the clear aligners field.
Methods: This is a call for participation targeting researchers in dental materials and orthodontics. The author serves as a technical
coordinator at a clear aligners' company serving worldwide. In many cases, dentists ask to avoid building composite engagers on teeth
as the patients are travelling outpatients and using such engagers is not applicable for them. However, these patients are dismissed as
optimal results are not guaranteed without using engagers. Composite engagers have the function of better anchorage and more force
precision commonly used in severe malalignment/malocclusion cases.
Results: Newmaterial needs to be developed to replace composite engagers that are routinely built up by dentists at dental clinics. The
author wishes to find material being applied by the patient him/herself rather than requiring several office recalls.
Conclusions: This discovery should consider biocompatibility, easy attach/detach and high sustainability to masticatory forces and
intraoral conditions.
