objective: extraction of premolars is believed to affect the eruption of third molars. this comparative study aimed to assess the change in angulation of third molars following first/second premolar extraction versus non-extraction orthodontic treatments. methods: this historical cohort study was conducted on patients assigned to three treatment groups: extraction of mandibular first premolars ...

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 d...

intentional tooth reimplantation can be an alternative treatment option for teeth with poor or hopeless prognosis where coronal and surgical endodontic treatment(s) are not possible. this technique may help to restore a natural tooth to function in preference to prosthesis/implant replacements. a 38-years old male was referred to private practice with persistent chronic apical periodontitis of ...

tooth transplantation can be considered a valid and predictable treatment option for rehabilitating young patients with permanent teeth loss. this study presents several cases of successful autogenous tooth transplantation with a 6-9 months follow-up. tooth auto-transplantation can be considered a reasonable option for replacing missing teeth when a donor tooth is available. the auto-transplant...

Previous studies have suggested that Bmp4 is a key Msx1-dependent mesenchymal odontogenic signal for driving tooth morphogenesis through the bud-to-cap transition. Whereas all tooth germs were arrested at the bud stage in Msx1(-/-) mice, we show that depleting functional Bmp4 mRNAs in the tooth mesenchyme, through neural crest-specific gene inactivation in Bmp4(f/f);Wnt1Cre mice, caused mandibu...
