Three-dimensional evaluation of dentigerous cysts in the Turkish subpopulation.

BACKGROUND: To investigate the radiological and demographic features, types, distribution, and treatment methods of dentigerous cysts (DC). METHODS: Panoramic radiographs and cone beam computed tomography (CBCT) images of patients diagnosed with DC based on biopsy results between January 2020 and December 2023 were examined. In patients from different age groups, the numbers, types and locations, and radiological features of DCs, associated changes in surrounding tissues, and treatment methods used were reviewed. RESULTS: Among 95 patients with DC (66 males, 29 females), sex and age distributions were comparable between those with a single cyst (n = 86) and those with two cysts (n = 9). Of 104 DCs, 44 were central, 38 were lateral, and 22 were circumferential. DC types were not significantly affected by sex, age group, or anatomical location. Circumferential DCs often caused displacement of the mandibular canal inferiorly. While enucleation was preferred for the treatment of central DCs, circumferential DCs were treated with marsupialization. CONCLUSIONS: In this study, which is the first to evaluate the DC types on CBCT images, the central type was the most common. Circumferential DCs were mostly treated with marsupialization. CBCT imaging can assist in determining DC types, and may provide guidance for treatment planning.

The evaluation of the effects of natural zeolite (Clinoptilolite) in diabetic rats on bone healing in dental extracting socket.

Objectives: The fact that clinoptilolite reserves are abundant and economical in the world, its toxic effects are not observed in clinical studies in humans and animals, and it has superior physical properties suggests that clinoptilolite may be an easily accessible product for the healing of tooth extraction wounds. The aim of the study was to evaluate the effects of cliniotilolite on bone tissue healing and bone formation in the extraction socket in experimentally diabetic rats by micro-CT analysis. Materials and methods: 36 male Wistar Albino rats were divided into 3 main groups as Healthy Control, Diabetes Control and Diabetes + Clinoptilolite. Afterwards, these groups were divided into 2 subgroups to be sacrificed on the 14th and 28th days, and each subgroup had 6 rats (n = 6). At the 14th and 28th days, the rats were sacrificed and the effects of clinoptilolite on bone tissue healing and bone formation in the alveolar socket were evaluated by micro-CT analysis. Results: According to the statistical analysis results, the difference between the groups in terms of bone volume, bone surface to bone volume, trabecular thickness and hounsfield units values, which are the parameters of the 14th day groups, was statistically significant (p < 0.05). Among the parameters of the 28th day groups, only the hounsfield units value was statistically significant (p < 0.05). Conclusion: The results of the study show that clinoptilolite can contribute to the healing of extraction wounds and bone formation.

Effects of a single intravaneous dose of zoledronic acid on bone healing following tooth extraction in ovariectomized rabbits.

OBJECTIVE: The present study is aimed to investigate the effects of administering a single intravenous dose of zoledronic acid (ZA) on bone healing following tooth extraction in ovariectomized rabbits. MATERIALS AND METHODS: Female, New Zealand rabbits were randomly divided into three groups including Control, ovariectomy + saline (OVX) and ovariectomy + zoledronic acid group (ZOL). Bilateral ovariectomy was performed to the rabbits in OVX and ZOL groups under general anesthesia. Control group underwent sham surgery. Eight weeks later, mandibular right incisors of all animals were extracted under general anesthesia. Before the procedure, Control and OVX groups were given saline and 0.1 mg/kg ZA was administered to ZOL group intravenously. All animals were sacrificed after 12 weeks. RESULTS: The findings of histopathological and biochemical evaluations reflected insignificant differences among study groups in vascular endothelial growth factor (VEGF), increases in osteoclasts, ossification, vascularization and mononuclear cell infiltration measures (p > 0.05). In contrast, bone morphogenic protein 2 (BMP-2), tumor necrosis factor alpha (TNF-α) and organization of the extraction wound differed significantly between groups (p < 0.05). CONCLUSION: The potential beneficial effects of ZA administration on the wound healing process following tooth extraction were demonstrated via serum TNF-α, BMP-2 and VEGF levels in an osteoporotic model in ovariectomized rabbits.
