                                                          Clinical presentation
           4.78                                           Traumatic wounds to the mouth involving foreign
                                                          bodies or very sharp dental overgrowths may bleed
                                                          profusely initially, but rapidly cease discharging and
                                                          in normal circumstances will heal spontaneously in
                                                          3–10 days. The presence of foreign material in the
                                                          wound will result in delayed healing, or the forma-
                                                          tion of a sinus tract communicating with the foreign
                                                          body. Eventually abscessation may occur. Such cases
                                                          may present with a painful soft-tissue swelling in the
                                                          oral cavity, particularly in the intermandibular space,
                                                          which may be palpable externally. Foetid discharges
                                                          may exude from sinus tracts associated with foreign
                                                          bodies and halitosis, hypersalivation and pain when
                                                          masticating may be observed. Abscessation involv-
                                                          ing the tongue can be extremely painful and is dif-
                                                          ficult to diagnose. Regional lymph nodes, including
                                                          the submandibulars, may be enlarged. Lacerations
           Fig. 4.78  Severe ulceration of the tongue can ensue   or ulceration (Fig. 4.78) of the tongue may be asso-
           where sharp dental prominences and dysmastication   ciated with reluctance to accept the bit or pain when
           are present.                                   ridden on the bridle.
