The Evaluation of Objective and Subjective Fate of Teeth in the Mandible Fracture Line and the Management-A Center's Experience

Abstract

Objective: The decision to retain or extract teeth in the line of mandibular fractures has been a subject of debate in much of the scientific literature, and there is a need for further evidence to clear this issue. Thus, the aim of this study was to investigate both the positive and negative effects of teeth in the line of mandibular fractures provide more evidence in this field, as well as take into consideration patients' quality of life after the surgery.

Methods: Patients after trauma with teeth in the line of mandibular fractures were included in this study. Open reduction and rigid internal fixation, elastic intermaxillary reduction were expected to achieve a satisfactory occlusion and/or anatomical reduction in the fragments as assessed by orthopantomogram, computed tomography scans, and clinical examination. The remaining cases had maxillomandibular fixation (MMF) with an arch bar and bridle wire. All the patients included in this study will take the Visual Analog Scale score evaluation before and after surgery subjectively to further verify the impact on their life qualify, as well as the further treatment needed.

Results: A total of 78 patients with teeth in the line of mandibular fractures were included in this study. Open reduction and rigid internal fixation was used in 37 patients, whereas another 35 patients accepted elastic intermaxillary reduction. Six cases underwent MMF. The number of involved teeth was 83. Three of the 83 teeth involved in the fracture lines healed with complications. In the cases where the teeth had been removed before fracture treatment, or in cases of delayed extractions, no complications were noted. The majority of the patients felt good about the whole treatment, however, 4 in the MMF group complained about worry about their oral health due to MMF leading to mouth open limitation.

Conclusion: The factors that should be considered for removal include the condition of the teeth and alveolar bone, the timing and the type of treatment, as well as the patients' desire, if possible. This is an individual-based decision that needs to consider more objective and subjective potential risks to avoid complications.
