Treatment Results of Dentigerous Cysts Managed by Marsupialisation, Enucleation or Enucleation with Platelet Rich Plasma-a Retrospective Study

Objective: This study aimed to evaluate the effectiveness of dentigerous cyst treatment with enucleation, marsupialisation or enucleation with platelet rich plasma (PRP) application. Materials and Methods: The study included 27 cases with dentigerous cysts. Demographic data, treatment modalities, treatment results, size of the bony defect before and after treatment and complications were analysed retrospectively. Patients were separated into three treatment arms. Group 1 comprised 11 patients treated with enucleation, group 2 comprised seven patients treated with enucleation and PRP and group 3 comprised nine patients treated with marsupialisation. Reductions in the size of the radiolucent area at the sixth month follow-up were compared in terms of the vertical and horizontal shrinkage of the lesion and monthly reductions in lesional area. Results: The treatment results of the three groups were similar. Only the group to which PRP was applied revealed significant vertical shrinkage (p=0.045). Preoperative lesional area and age appeared to be factors significantly affecting bone regeneration (p0.05). Conclusion: Enucleation and marsupialisation are successful treatment modalities for dentigerous cysts. PRP application enhanced bone gain. Marsupialisation enhanced bone integrity and promoted the eruption of permanent teeth.
