A 74-year-old man presented with a 6 × 6-cm expansile, ulcerated mass on the right lateral palate. A clinical diagnosis of squamous cell carcinoma was rendered. A biopsy was performed, and the specimen showed multiple histologic patterns of ameloblastoma inconclusive of odontogenic or sinonasal origin. Cone beam computed tomographic imaging demonstrated a well-defined unilocular mass in the right maxilla extending up to the nasal cavity. A surgical resection was performed and confirmed the diagnosis of maxillary ameloblastoma with extension into the nasal cavity. This dilemma in delayed diagnosis led to a literature search for similar maxillary ameloblastoma cases with extension into vital structures. In 45 cases previously reported in the literature, the median age of patients with maxillary ameloblastoma was 50 years, and there was extensive involvement of adjacent vital structures. The nasal cavity/sinonasal region (24/45), orbit/orbital floor (12/45), multiple fossae (5/45), and base of the skull (4/45) were the most common extensions of maxillary ameloblastoma. Fifteen patients had lesions with multiple extensions, and 1 patient showed lung metastasis. The most common histologic presentation was the follicular pattern, followed by the plexiform pattern or mixed follicular and plexiform patterns. Surgical interventions were performed on most patients, with the majority undergoing maxillectomy. Differentiating primary sinonasal ameloblastoma from gnathic ameloblastoma with sinonasal extension is challenging, and this article discusses subtle radiographic criteria and symptoms that aid in the distinction of both types. The authors suggest that variants of maxillary ameloblastoma with extensive involvement of the sinonasal region, orbit, or base of the skull be classified with a clinical diagnosis of maxillofacial ameloblastoma, regardless of the tumor origin.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"72 6","pages":"54-61"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142498619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the course of CAT was adjusted in favor of an individualized protocol to alleviate her occlusal symptoms until orthodontic treatment was completed.

Several procedures for decontaminating the implant surface and promoting bone growth have been established to treat this condition. The purpose of the present case report was to describe the decontamination method used to achieve peri-implant health in a 60-year-old man who had a single implant that had been in function in the mandibular left molar region for 10 years. The implant, in the region of the first molar, was osseointegrated and showed radiographic bone loss associated with a probing depth of 8 mm and bleeding on probing. The diagnosis was peri-implantitis, and a surgical treatment approach was selected to enable decontamination of the area with a combination of mechanical debridement, tetracycline hydrochloride (500 mg/mL), and photodynamic therapy. After the decontamination process, a sodium bicarbonate spray device was used, and a guided bone regeneration protocol with a xenogeneic graft and collagen membrane was performed to reestablish the peri-implant bone height. A connective tissue graft was placed to obtain a better biological seal and increase the peri-implant keratinized mucosa. Follow-up examinations performed 30 days, 5 months, 3 years, and 6 years after the surgical procedure revealed new bone formation and progressively reduced probing depths.

A 5-year-old boy, accompanied by his mother, sought dental care for dental caries and tooth pain. Clinical and radiographic examinations revealed active caries, a supernumerary primary tooth in the region of the mandibular right second premolar, and severe ankylosis of the primary mandibular right second molar. The treatment plan involved extraction of the supernumerary tooth as well as sectioning and extraction of the ankylosed molar. When the patient was 6 years old, the permanent mandibular right first molar showed signs of an altered eruptive process, and orthodontic treatment was initiated. A unilateral band-and-loop space maintainer with coil springs designed to move the permanent first molar was placed on the primary first molar. A new panoramic radiograph, obtained when the patient was aged 7 years, suggested the presence of an odontoma in the apical region of the primary maxillary right canine. Surgical removal and histopathologic examination of the lesion confirmed that it was a developing odontoma. After surgery, due to occlusal anomalies that included transverse maxillary deficiency, deep overbite, and midline deviation, the patient underwent rapid maxillary expansion therapy with a Haas-type appliance. When the patient was 8 years old, orthodontic treatment continued with a removable palatal Hawley expander and a orthodontic mandibular lingual arch. Currently, at the age of 9 years, the child is still undergoing fixed orthodontic treatment after surgical exposure of the impacted permanent maxillary right canine and bonding of an orthodontic attachment to enable traction.

This case report describes a single-appointment chairside technique for placement of ceramic restorations in posterior teeth. A patient presented for treatment of her mandibular right first molar, which had a fractured resin-based composite restoration. Due to the presence of vital pulp, extent of the restoration, and presence of caries in the tooth, the following treatment plan was proposed: placement of a lithium disilicate glass-ceramic onlay fabricated with a computer-aided design/computer-aided manufacturing workflow. After the dentist removed the restoration and performed selective caries removal, structural analysis guided the reduction of the buccal cusps. Immediate dentin sealing was performed with a 2-step self-etching adhesive system, and a 1-mm-thick layer of flowable resin-based composite was placed as a resin coating. A digital impression was obtained, the onlay restoration was designed, and a lithium disilicate block was milled and subsequently crystallized. When the onlay was completed, the tooth preparation was sandblasted, selectively etched, and coated with a universal adhesive. The intaglio surface of the onlay was cleaned and primed, the onlay was bonded with dual-cure resin cement, and occlusal adjustments were completed. Follow-up examinations at 1 and 4 months revealed the clinical success of the case. From start to finish, it takes approximately 2.5 hours to produce a single-appointment chairside restoration.

In both cases, instrumentation was extended 1 mm beyond the apical foramen to facilitate drainage through the root canal, because it was assumed that the periapical lesion could be cystic.
