Background. A radicular cyst is the most common odontogenic cyst of inflammatory origin. Radiographically, it commonly\ndemonstrates clear unilocular radiolucency; radicular cysts with multilocular radiolucency are quite rare. Case Presentation. A\n64-year-old Japanese man who presented with a bilocular radiolucent lesion in his left mandible was referred by a dental clinic\nto our oral and maxillofacial surgery department. He had no particular subjective symptoms. Orthopantomography and\ncomputed tomography (CT) revealed an 18mm*15mm lesion with well-defined bilocular radiolucency in the left mandible\nexpanding from the distal side of a canine tooth to the bottom of the 2nd premolar. The lesion included the roots of the 1st and\n2nd premolars. The root of the 2nd premolar showed knife-edge resorption. Although the 1st premolar was nonvital, the 2nd\npremolar was a vital tooth. As differential diagnoses, a radicular cyst, ameloblastoma, odontogenic keratocyst, pseudocyst, and\nothers might be considered. We performed a total resection of the bilocular lesion and diagnosed the lesion as a radicular cyst\nwith tooth structure components inside. The tooth structure components represented lamellar structures of cementum; they\nwere located only in the proximal part (under the 1st premolar) of the lesion. The distal part of the lesion presented distinctive\ninflammation without tooth structure components. Conclusion. We encountered a rare case of a bilocular radicular cyst with\ntooth structure components inside....
The aim of this case report is to show that bone remineralization around dental implants with a history of peri-implantitis is\npossible after irritant factors are removed and only conservative treatment is performed. Patient came to the clinic after three\nyears of dental implant placement complaining about swelling, sensitivity and gingiva color changes at the posterior part of\nthe maxilla. During radiographic and intraoral examinations peri-implantitis of the #24 implant site was diagnosed. The\nsurgical treatment method was rejected and performed conservative treatment instead. The outcome is promising;\nperiapical radiographs three months later showed bone remineralization as well as stable bone after 10 years. A key clinical\nmessage: Bone remineralization around dental implants with a history of peri-implantitis is possible after irritant factors\nare removed and conservative treatment performed....
Background: A common strategy in the non-extraction treatment of Class II molar relationship is maxillary molar\ndistalization, which could increase lower face height and cause clockwise mandibular rotation. The aim of this\nretrospective study was to analyse the effects on vertical dentoskeletal dimension of young adults treated with\nsequential distalization with orthodontic aligners.\nMethods: Lateral cephalometric radiographs of 10 subjects (8 females 2 males; mean age���....
Background. The immediate placement of a dental implant could represent an option treatment for the rehabilitation of a\npostextractive missing tooth socket to replace compromised or untreatable teeth, with the advantage of single-session surgery. In\nthis way, the anatomy of the alveolar bone defect, the preservation of the buccal cortical bone, and the primary stability of the\nfixture represent the critical factors that consent a precise implant placement. Objective. This case report describes a novel\nfixture design for postextractive alveolar socket immediate implant. Methods. Two patients (25 and 31 years old) were treated\nfor postextractive dental implant placement to replace both central upper incisor teeth with four implants. The residual bone\nimplant gap was not filled with graft or bone substitute. The restoration was provided following a standard loading protocol by\na cement-sealed prosthetic abutment. Results. Clinically, all implants positioned showed an excellent insertion torque. No\npostoperative complications were reported. At 6 months of healing, the buccal cortical bone and the implant stability were\npresent and well maintained. Conclusion. The evidence of this study allows us to underline the possible advantages of this new\nfixture design for postextractive implant technique....
Background: The purpose of this experiment was to assess the push out bond strength of Polydimethylsiloxane\nsealers (GuttaFlow 2 and GuttaFlow Bioseal by Colteâ??ne/Whaledent, Altstatten, Switzerland). AH Plus (Dentsply,\nDeTrey, Konstanz, Germany) was used as a reference material for comparison.\nMethods: Thirty root slices were prepared from the middle third of 10 mandibular premolarsâ?¦â?¦â?¦...
Background: This study aimed to evaluate the prevalence of tooth wear among preschool children in Jakarta,\nIndonesia, and examine the risk factors associated with its occurrence.\nMethods: An epidemiological survey was conducted with a cross-sectional study design. The participants were\nrecruited via cluster sampling. Tooth wear was clinically assessed by one examiner using the Basic Erosive Wear\nExamination (BEWE) criteria. The childrenâ??s caries experience was also recorded. The parents of the participating\nchildren completed a self-administered questionnaire to answer demographic questions about the children and\ngather information about the childrenâ??s diet and oral health behaviors as well as the parentsâ?? dental health-related\nknowledge. The data were analyzed using the Chi-square test and binary logistic regression.\nResults: A total of 752 five-year-old children were invited to participate, with 691 (92%) enrolling in the study.\nTooth wear occurred in 23% (161/691, BEWE > 0) of the participants, in which 78% (125/161) had at least one\nmoderate tooth wear status (BEWE = 2). The consumption of citrus drinks, fruit juice, and vitamin C supplement\ndrinks, together with the childâ??s caries experience, the fatherâ??s education level, and the familyâ??s socioeconomic\nstatus, were significantly associated with tooth wear.\nConclusions: The five-year-old preschool children in Jakarta had a relatively low prevalence of tooth wear. Those\nconsuming more acidic drinks, those with a higher socioeconomic status, and those with an absence of caries\nexperience had a higher risk of tooth wear....
