A retrospective study was performed in 100 dogs with 121 mandibular and 21 maxillary fractures. Dogfight (43.0 %) and automobile (12.0 %) trauma were the most common etiologies for fracture. The cause of fracture was unknown in 23.0% of the cases, while pathologic fractures occurred in 13.0 % of cases. Young dogs (< 1-year-old) and dogs > 8-years of age were most affected. Mandibular fractures occurred in 90 dogs (90.0 %), with two dogs (2.2 %) having concurrent maxillary fractures. Maxillary fractures only were diagnosed in 10 dogs (10.0 %). The molar region (47.1 %) was the most commonly affected location for mandibular fracture, followed by fractures of the symphysis and parasymphysis (30.6 %), premolar region (17.4 %), angular process (4.1 %) and vertical ramus (0.8 %). In fractures of the mandibular region, the mandibular first molar tooth was often (85.9%) involved while the canine teeth were involved in 67.5 % of symphyseal and parasymphyseal fractures. The most common fracture of the maxilla was the maxillary bone (52.4 %), followed by the incisive (33.3 %), palatine (9.5 %), and nasal (4.8 %) bones.

Mandibular First Molar

Mandibular fractures at the level of the first molar tooth (M1) were assessed in 29 dogs. Patients included in this study demonstrated fractures involving the M1 tooth, tooth bud, or alveolus (if tooth was absent). Diagnostic imaging evaluation included intraoral dental radiography and/or computed tomography (CT) with 3D reconstruction. The distal root was involved in 55.2% of cases, mesial root involvement in 34.5% of cases, and the tooth was absent in 10.3% of cases. Fractures were described in the rostral-to-caudal direction. Fractures tended to occur in the caudoventral direction ( P = .057). Cases with CT imaging were also evaluated in the buccolingual direction. Fractures were found to occur significantly more frequently in the caudolingual direction ( P = .022). When classifying fracture patterns along M1 according to a previously published fracture classification system, it was noted that fractures occurred significantly more frequently in either the mesial ( P < .001) or distal ( P < .001) roots by coursing along the periodontal ligament space and communicating with the periapical region. Active or nonworsening periodontitis was described as radiographic or tomographic evidence of (>25%) bone loss in the vertical or horizontal direction. Periodontitis was associated with 7 (24.1%) cases. These results help frame the challenges associated with fracture repair at the M1 location. Treatment planning considerations should include limited structural support caudal to fractures involving the distal root, more frequent involvement of the distal root over the mesial root, risk for poor endodontic prognosis, and the predilection for unfavorable fracture patterns to occur.

The Relationship

ABSTRACTObjectives: In this retrospective study, we measured the relationship between the presences of impacted or unerupted teeth in the mandible and mandibular fractures.Methods: The records and radiographs of 41 patients with mandibular fracture associated with impacted or unerupted teeth were examined. The presence of impacted or unerupted teeth were assessed for each patient and related to the occurrence of fractures of mandible.Results: Patients with fracture in the impacted or unerupted teeth area present had a 1,73 times greater chance of an mandibular fracture than patients with no fracture in the impacted or unerupted teeth area. There was a statistically significant variation in the risk for a mandibular fracture depending on impacted or unerupted teeth presence (x2=5.29, P< .05).Conclusion: The presence of an impacted or unerupted teeth significantly increases the likelihood of an mandibular fracture.

ABSTRACT Objectives: This study was aimed to assess the impacts of delay treatment of mandibular fracture and its complications. In addition risk variables related such as time to repair, fracture types, substance abuse, causes, surgical management, muddling or complications and duration of clinic stay were also evaluated. Materials and Methods: The data of patients attending the Newcastle General Hospital, UK for the management of mandibular fractures were probed. This retrospective clinical trial conducted over 6 months, included 91 patients attending trauma operating theatre during weekdays or weekends. Data were analyzed for time to admission and treatment and its relationships to various factors using SPSS version 20 (SPSS Inc., Chicago, IL). Results: Time to treatment from the point of admission was 31.50 ± 3.83 h during week days that has been significantly more for patients attending the hospital at weekends or nights. Similar trend was observed for total summative time from the incident to treatment analysis. Conclusions: This investigation has demonstrated that the rate of infection and postoperative complications following surgical treatment of mandible fractures can be eased off by reducing the waiting time from presentation to the emergency and to the operating theater.

PURPOSE: To evaluate the bone healing of mandibular fractures following the use of Portland cement. METHODS: Thirty-two male Wistar rats were divided into control and experimental groups. In the control group the rats were submitted to a mandibular fracture, which was reduced, and the soft tissues were sutured. In the experimental group the rats had the mandibular fracture reduced and maintained with the Portland cement. The animals were euthanized 7 and 21 days after surgery by injecting a lethal dose of anesthetic. The following variables were studied: weight of the animals, radiographic images, histopathological features and time of surgery. RESULTS: A weight loss was observed in the specimens of both groups at the different times of evaluation, a greater difference in weight before and after surgery being found in the experimental group, which was statistically significant (p <0.05, p = 0.041). From the histological point of view, with a margin of error (5.0%) the only two significant differences (p <0.05) recorded in the variables were "Material deployed" and "Bone resorption" during the evaluations at 7 and 21 days, respectively. CONCLUSION: The Portland cement served to promote bone healing.
