Brief Summary:

The purpose of this study is to determine the contribution of the innervation of the contra-lateral mandibular nerve for the innervation of the lower lip area.

The investigators hypothesis is that the sensation of the lower lip is contributed by both mandibular nerves (from both sides of the jaw).
