Four months earlier the right mandibular 3rd and 4th pre-molars (407 & 408) had been extracted, but the extraction site did not heal properly. The extraction site had beensurgically explored three months later and a bacterial culture revealed a Pasteurella infection at that time. Treatment with Orbax resulted in minimal improvement.
