Trichorhinophalangeal syndrome type 1 (Giedion syndrome): A case report with literature review.

Introduction And Objectives: Trichorhinophalangeal syndrome (TRPS) is a rare multisystem disorder characterized by abnormalities in the hair (tricho), nose (rhino), and digits (phalangeal). A variety of nonspecific intraoral findings have been reported in the literature, including hypodontia, delayed tooth eruption, malocclusion, a high-arched palate, mandibular retrognathia, midface hypoplasia, and multiple impacted teeth. In addition, supernumerary teeth have been detected in several persons with TRPS, especially type 1.

Reimplantation of an inverted maxillary premolar: case report of a multidisciplinary treatment approach.

Inversion of premolars is an extremely rare condition, which usually requires extraction. This case report describes the inversion of an impacted maxillary second premolar in an 11-year-old male, and the multidisciplinary treatment approach for bringing the tooth into a normal position within the arch. In order to provide sufficient space for surgical reimplantation of the tooth, the mesially-drifted neighbouring maxillary first molar was first endodontically treated, followed by orthodontic distalization of the tooth.

Implant stability and bone density: assessment of correlation in fresh cadavers using conventional and osteotome implant sockets.

Objective: To compare the primary stability of implants placed in conventional and osteotome sites and to evaluate the level of correlation between cutting torque measurements, resonance frequency analysis (RFA), and bone density.

Materials And Methods: Eight human femoral heads were scanned with computed tomography for bone density measurements as Hounsfield units (HU), and individualized computed tomography-based surgical stents were prepared for placement of implants. Five implant sockets were prepared in each collum (CoF), caput (CaF), and trochanter (Tr-MM) section of the femoral heads using the conventional drilling technique or by a combination of drilling and use of an osteotome.
