Donor tooth root morphology and periodontal ligament integrity are key factors influencing success. We report a semi-immediate autotransplantation of a maxillary third molar with a 90° divergent root into a site previously affected by a periapical abscess. After the extraction of the compromised tooth (#15) and removal of the interradicular septum, the site was left to heal to allow soft tissue closure and infection resolution. During this period, CBCT imaging and a 3D-printed donor tooth replica (CARP model) were used to plan the procedure, including the intended root amputation. Two weeks later, autotransplantation was performed. The recipient site only required soft tissue and granulation tissue management, with no additional bone preparation, allowing for a minimally traumatic approach. The donor tooth was transplanted with an extraoral time of under 6 min. At the 18-month follow-up, the tooth remained functional, asymptomatic, and radiographically stable. This case highlights the feasibility of delayed autotransplantation following infection and the clinical value of combining imaging with prototyping in surgical planning-particularly when dealing with donor teeth with unfavorable root anatomy.","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2025 ","pages":"6655016"},"PeriodicalIF":0.7,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12253988/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144627399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In rare instances, ectopic molars may be associated with dentigerous cysts, particularly within the maxillary sinus, posing challenges for diagnosis and management. This report discusses a rare case of a 58-year-old male who presented with chronic right maxillary sinusitis, intermittent facial pain, and purulent nasal and oral discharge. Radiological evaluation, including cone beam computed tomography (CBCT), revealed a completely opacified right maxillary sinus containing an ectopic maxillary molar. Additionally, a large cystic lesion consistent with a dentigerous cyst was found, occupying the entire sinus cavity. Surgical management was performed using the Caldwell-Luc approach under general anesthesia. This involved creating a bone window in the anterior maxillary wall to facilitate the removal of the ectopic tooth and the associated cystic lesion. Histopathological examination confirmed the presence of a dentigerous cyst exhibiting chronic inflammatory infiltration and fibrosis. Ectopic molars in the maxillary sinus are often asymptomatic but can present with recurrent sinusitis, pain, and oroantral communication. The existence of a large dentigerous cyst heightens the risk of complications and may obscure radiological interpretation due to sinus opacification. This case highlights the necessity of comprehensive imaging and early surgical intervention to prevent long-term complications. Awareness of such rare conditions can help clinicians in prompt diagnosis and appropriate management, ultimately preserving sinus function and minimizing further issues.","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2025 ","pages":"2436615"},"PeriodicalIF":0.7,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12245510/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144609949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This planning can lead to crown margins that either contact or encroach upon the remaining alveolar bone, a consequence of previous supraeruption. Supraeruption is associated with periodontal growth, where the periodontal ligament and bone develop concurrently with the erupting tooth. For successful outcomes in such cases, it is crucial to perform bone recontouring before implant placement, creating adequate space for the biological width, which is essential for achieving a segmented, implant-supported, fixed prosthesis. In the patient described in this case report, who received eight implants and four fixed partial prostheses, peri-implantitis required the removal of a posterior implant after 18 years of prosthesis use, necessitating retreatment in the corresponding quadrant. Notably, interproximal contacts between the prostheses had opened, likely due to continued craniofacial growth and bone remodeling, although this did not affect the patient's functionality. The recontoured bone and soft tissues maintained their position, preserving both the interproximal papillae and gingival contour in the esthetic zone.","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2025 ","pages":"6660284"},"PeriodicalIF":0.7,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12221550/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144555238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case report documents the use of a computer-aided design/computer-aided manufacturing (CAD/CAM) surgical guide for miniscrew placement in a Class II subdivision treatment. Case Presentation: A 17-year and 1-month-old female presented with a skeletal Class I relationship, but mild mandibular skeletal and dental midline shift to the right relative to the facial midline. A full-step Class II molar relationship on the right side and slight Class III molar relationship on the left side and a 4.0 mm deficiency of space in the maxillary were noticed. Using CAD/CAM technology, a surgical guide was designed virtually and 3D printed for predrilling. With the surgical guide, one ø1.3 mm twist drill was chosen to prepare a 4-5 mm deep hole in the alveolar process distobuccal to the maxillary right second premolar. A ø1.4 mm × 8.0 mm miniscrew was inserted into the prepared hole. With this miniscrew, the unilateral Class II relationship was corrected successfully by distalization of the unilateral maxillary dentition on the Class II side after 13 months of treatment. Conclusion: Application of CAD/CAM surgical guide is very helpful for placement of the miniscrew. Class II subdivision may be treated by distalizing unilateral maxillary dentition on the Class II side using the miniscrew.","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2025 ","pages":"3082753"},"PeriodicalIF":0.7,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12213053/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case series presents the long-term benefits of PR with up to 13 years of follow-up. A total of six teeth in five patients were treated for intrabony defects using PR. The treatment involved the elevation of a mucoperiosteal flap, root instrumentation, and filling the bony defect with bone substitutes. Following PR, a significant reduction in probing depth (PD) was observed (mean 9.5 ± 1.87 mm; p = 0.03) along with a statistically significant gain in clinical attachment level (CAL) (mean 8.33 ± 1.03 mm; p = 0.03). Radiographic bone defect fill at the defect site was also verified (mean 9.67 ± 2.25 mm; p = 0.03). This case series demonstrated that PR led to reduced PD with minimal gingival recession, gain in CAL, and bone fill at defect sites, even in complex periodontal defects extending to the apical portion of the root, over a follow-up period of up to 13 years, indicating it as an effective and predictable treatment alternative.","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2025 ","pages":"6925321"},"PeriodicalIF":0.7,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12185179/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article explores the combined use of dental bleaching and enamel microabrasion as effective treatments for managing fluorosis-induced discoloration. Dental bleaching, a widely used method for lightening extrinsic and intrinsic stains, has shown promising results in improving the overall appearance of discolored teeth. Enamel microabrasion, which involves the mechanical removal of superficial enamel stains, can enhance the effectiveness of bleaching by addressing more severe or resistant discoloration. The article reviews the mechanisms of these treatments, their clinical indications, and their outcomes in patients with varying degrees of dental fluorosis. Additionally, potential side effects, such as tooth sensitivity and enamel damage, are discussed, emphasizing strategies to minimize these risks. By combining these methods, clinicians can offer more comprehensive, individualized care for patients seeking cosmetic improvements for fluorotic teeth, with attention to both aesthetic outcomes and long-term dental health.","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2025 ","pages":"9972925"},"PeriodicalIF":0.7,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12178729/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144334080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
