The cementomas are derived from the periodontal ligament and a diversified group of nonrelated lesions producing cementum-like material. The diagnostic term, Cementoma, has encompassed several unrelated lesions : periapical cemental dysplasia, benign (true) cementoblastoma, cementifying fibroma and familial multifle (gigantiform) cementoma. The authors treated one case of benign cementoblastoma & the other of cementifying fibroma by conservative enucleation & curettage. By follow up check of the patient, We obtained of good result without any signs of recurrence of the lesions.

Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. Invasion into the maxillary sinus by a CCOT is not a typical, and the recurrence of the cystic variant of CCOT in the posterior maxilla is rare. This report describes a recurrent CCOT occupying most of the maxillary sinus of a 24-year-old male patient. As a treatment, marsupialization was carried out as a means of decompression, and the involved teeth were all endodontically treated. Afterward, surgical enucleation was performed. The size of the lesion continued to shrink after marsupialization, and the maxillary sinus restored its volume. This patient has been followed-up for 3 years after the surgery, and there have not been any signs of recurrence.

Objectives: Since World Health Organization reclassified the odontogenic keratocyst as a keratocystic odontogenic tumor(KCOT) in 2005, management of KCOT remains controversial. The purpose of the this study is to present a current concept of the treatment of the KCOT. Methods: Recent articles were focused on the method of the surgical therapy and the recurrence rate of KCOT. Results: The treatment modality is divided into conservative treatment-such as simple enucleation with or without curettage or marsupialization-and aggressive treatment including peripheral ostectomy, chemical curettage with Carnoy's solution, and resection. Conclusions: Keratocystic odontogenic tumors have higher recurrence rates than other odontogenic lesions; thus, the selected type of treatment is very important.

A dentigerous cyst is an epithelium-lined sac that surrounds the crown of an impacted, embedded, or unerupted tooth. Many surgical procedures have been described for the elimination of dentigerous cyst, but they can be devided into two basic group: enucleation and marsupialization. Marsupialization is a conservative technique which allows the reduction or elimination of a cystic lesion by making it an accessory compartment to the oral cavity and it is the best way to conserve a tooth affected by dentigerous cyst and to permit its eruption, especially in young patient. After using marsupialization to treat dentigerous cyst associated with the crown of unerupted premolar in young patient, the results were as follows: 1. Reduction of bony expansion and rapid bone regeneration without infection and recurrence were observed. 2. Normally spontaneous eruption of involved teeth were permitted, as well as loss of affected tooth was avoided. 3. Follow-up examinations revealed no complication and recurrence.

Dentigerous cyst (DC) is an odontogenic cyst associated with the crown of an impacted, embedded, unerupted, or developing tooth. It is the second most common type of odontogenic cysts, accounting for 14% to 24% of all jaw cysts. Although these cysts occur more frequently during the second and third decades of life, they can also be found in children and adolescents in the mixed dentition stage. Treatment of the odontogenic cyst involves enucleation or marsupialization/decompression methods. The latter approach is preferred for larger cysts, and it is especially helpful in adolescent patients in conserving the unerupted permanent successors. The aim of treatment for DC is the complete elimination of pathology and maintenance of dentition with minimal surgical intervention. Recently defined criteria for the selection of treatment modality include the cyst size and location of the cyst, patient age, dentition involved, stage of root development, position of the tooth involved in the jaw, and relationship with the surrounding vital structure. Marsupialization or decompression technique has been advocated by several authors for treating DCs among young patients. In this conservative technique, the creation of an accessory cavity helps relieve intra-cystic pressure and accelerate the healing of cystic lesion. This technique has been successfully performed and is indicated for growing children and adolescents. Here, we report a large cyst lesion in the mandible treated by marsupialization for conservative management. In conclusion, successful reduction in size was achieved, and intraoperative complication could be prevented.

Background: Fibrous dysplasia (FD) is a rare, sporadic, and benign congenital condition in which normal cancellous bone is replaced by fibro-osseous tissue with immature osteogenesis. FD localized in the cranial and facial bones is called craniofacial fibrous dysplasia (CFD). Cystic degeneration in CFD cases is rare; cystic degeneration appearing in both the maxilla and the mandible FD lesion is even rarer. The aim of this article was to report a case of fibrous dysplasia of the mandible and maxilla complicated by nonspecific cystic degeneration. Case presentation: A 30-year-old woman presented with a rare case of non-specific cystic degeneration in a mandible and maxilla FD lesion that occurred 11 years after surgery. She was diagnosed with polyostotic CFD and underwent maxillary and mandibular bone contouring. Cyst enucleation under general anesthesia was performed in the mandibular region due to pain and discomfort. Conclusions: In cases involving non-aggressive and non-invasive FD cystic degeneration in focal areas, conservative treatment is recommended. However, if cystic degeneration of FD develops rapidly and causes discomfort, pain, or dysfunction, surgical treatment should be considered.

Background: Cyst enucleation, which extracts only the tumor with the application of Carnoy's solution (CS), has been suggested as a conservative treatment with a low recurrence rate and morbidity. However, there has been a concern that CS's contact with inferior alveolar nerve (IAN) can cause neurons to degenerate and cause sensory dysfunction. The purpose of this retrospective cohort study aimed to investigate the neurosensory function after surgical treatment with or without the application of CS. Methods: While controlling the effects of sex, age, follow-up period, and invasion size of the tumor, we performed the binary logistic regression analysis to examine whether or not the sensory function of the patients who were treated with CS (n = 19) for the cyst enucleation procedure was significantly different from those who were not treated with CS (n = 58) at the end of the follow-up period. Results: The logistic regression result showed that the use of CS was not significantly related to the normalness of sensory function at the end of the follow-up period. Rather, the invasion size of the cyst was significantly associated with sensory dysfunction. Conclusions: CS may be used for patients who are diagnosed with OKC and UAM without much fear of its impact on sensory dysfunction. However, a small number of patients who were treated with CS experienced severe sensory damage and did not recover at the end of the follow-up period, suggesting the need for further analysis of these patients.

Objectives: The necessity of retrograde filling after apicoectomy is controversial in cases of non-inflammatory cysts as opposed to bacteria-related periapical abscesses. This study aims to investigate whether the presence or absence of retrograde filling during apicoectomy has differential long-term prognostic implications between inflammatory and non-inflammatory cysts. Materials and Methods: This retrospective study included patients who underwent tooth apicoectomy during jaw cyst enucleation between 2013 and 2022, and who underwent follow-up cone-beam computed tomography for at least 6 months. The prognosis of the tooth was evaluated during the follow-up period according to the cyst type, the presence or absence of retrograde filling, mandible or maxilla, and location. Results: A total of 147 teeth was included in this study. All the operated teeth underwent preoperative root canal treatment by an endodontic specialist. Apicoectomy was performed for 119 inflammatory cysts and 28 non-inflammatory cysts. Retrograde filling was performed on 22 teeth with inflammatory cysts and 3 teeth with non-inflammatory cysts. All teeth survived the 3.5-year follow-up (range, 1.0-9.1 years). However, 1 tooth with an inflammatory cyst developed complications 1 year after surgery that required re-endodontic treatment. Conclusion: The prognosis of a tooth treated by apicoectomy without retrograde filling during cyst enucleation is favorable, regardless of the cyst type.
