Autogenous Transplantation for Replacing a Hopeless Tooth

Autogenous tooth transplantation (ATT) is a simple and reasonable choice for replacing the missing teeth when a proper donor tooth is available. This report presents a case of successful ATT of a maxillary right third molar for replacement of mandibular right second molar with a concomitant endodontic-periodontal disease. The mandibular second molar was believed to be hopeless due to a severe damage to coronal tooth structure, inappropriate root canal treatment and apical radiolucency. After extraction of mandibular second molar and maxillary third molar (the donor), the tooth was re-implanted into the extracted socket of second molar site. Root canal therapy was then performed. After 3 years, clinical and radiographic examinations revealed satisfying results, with no signs and symptoms. The patient is asymptomatic and the transplanted tooth is still functional with no signs of marginal periodontal pathosis. Radiographies showed bone regeneration in the site of previous extensive periapical lesion, normal periodontal ligament with no signs of root resorption.Keywords: Autogenous; Auto-Transplantation; Endodontic; Surgical Procedure; Third Mola

Case Report of Long-Term Follow-Up of an Unusual Oral Rhabdomyosarcoma with an Intraosseous Origin

Background: Rhabdomyosarcoma, originating from skeletal muscle tissue, is the most prevalent soft tissue sarcoma in children. Its occurrence within the oral cavity is relatively uncommon, with jaw involvement being extremely scarce, accounting for only 0.04% of all head and neck malignancies. This report aims to present an exceptionally rare case of oral rhabdomyosarcoma with intraosseous origin in the jawbone of a 12-year-old boy. It evaluates the long-term efficacy of a novel combined surgical treatment approach and its impact on the patient’s health.Method: Following several unsuccessful chemotherapy treatments, the tumor was removed with debulking surgery. Considering the patient’s young age, the surgical plan was carefully modified to minimize psychological and social problems, decrease post-operative consequences such as disabilities, and maintain the patient’s look. A marginal resection from both inside and outside of the mouth was selected, resulting in a thorough resection of the tumor to preserve mandibular continuity.Results: After the surgical intervention and follow-up chemotherapy, radiographic evaluations showed no signs of abnormalities or metastasis. The patient was scheduled for annual follow-up appointments to monitor long-term functionality and satisfaction with the treatment outcomes.Conclusion: Nearly a decade after the surgery, the patient remains alive, in good health, fully functional, and shows no signs of tumor recurrence

Nonsurgical treatment of an extensive radiolucent lesion, a case report

    Long-term success of endodontic treatment is precisely and completely dependent on adequate and appropriate cleaning and shaping of the root canal along with proper and correct obturation of the entire prepared space.This paper aims to report an exceptionally and novel non-surgical and orthograde endodontic therapy on maxillary right central incisor with an extensive radiolucent lesion. A 17-year-old male with an unusual extensive radiolucent lesion in the anterior part of upper jaw is reported. After cleaning and shaping of the root canal, Calcium Hydroxide was placed in the canal for 6 months and then Obturation was performed. 6 and 20 months follow-ups showed significant changes, including bone formation and periapical healing at the site of the lesion. The patient was asymptomatic. After 20 months, complete radiographic and clinical healing of the periapical lesion was observed

Effect of alcohol on Brain-Derived Neurotrophic Factor (BDNF) blood levels: a systematic review and meta-analysis

Abstract Brain-Derived Neurotrophic Factor (BDNF) is a vital protein involved in neuronal development, survival, and plasticity. Alcohol consumption has been implicated in various neurocognitive deficits and neurodegenerative disorders. However, the impact of alcohol on BDNF blood levels remains unclear. This systematic review and meta-analysis aimed to investigate the effect of alcohol consumption on BDNF blood levels. A comprehensive search of electronic databases was conducted to identify relevant studies. Eligible studies were selected based on predefined inclusion criteria. Data extraction was performed, and methodological quality was assessed using appropriate tools. A meta-analysis was conducted to estimate the overall effect size of alcohol consumption on BDNF levels. A total of 25 studies met the inclusion criteria and were included in the final analysis. Alcohol use and BDNF blood levels were significantly correlated, according to the meta-analysis (p = 0.008). Overall, it was discovered that drinking alcohol significantly decreased BDNF levels (SMD: − 0.39; 95% CI: − 0.68 to − 0.10; I2: 93%). There was a non-significant trend suggesting that alcohol withdrawal might increase BDNF levels, with an SMD of 0.26 (95% CI: − 0.09 to 0.62; I2: 86%; p = 0.14). Subgroup analysis based on the source of BDNF demonstrated significant differences between the subgroups (p = 0.0008). No significant publication bias was observed. This study showed that alcohol consumption is associated with a significant decrease in BDNF blood levels. The findings suggest a negative impact of alcohol on BDNF levels regardless of alcohol dosage. Further studies are needed to strengthen the evidence and elucidate the underlying mechanisms
