Abnormalities were detected only in 24 (2.3%) of 1053 skull X-ray examinations performed in cases of suspected head trauma, at a cost of $1461 per positive finding. Only in six cases (0.6%) was treatment influenced by the radiological findings. Skull X-ray examination is indicated if a depressed fracture, compound fracture, or radio-opaque foreign body is suspected, and these patients are reliably selected by certain clinical criteria. The skull X-ray film is not a reliable guide to the presence or extent of intracranial injury, nor is it a substitute for careful clinical evaluation, observation and re-evaluation. The medicolegal implications of this restrictive policy are discussed.

Clinical and radiographic outcomes of extra-short implants (≤ 6 mm) in the posterior atrophic jaws: a retrospective cohort study.
Int J Implant Dent
January 2025
Department of Neurosciences, School of Dentistry, University of Padua, Padua, Italy.
Objective: This study aimed at investigating implant survival rate and marginal bone loss (MBL) around extra-short implants. The impact of the loading protocol and of the use of an intermediate abutment was also evaluated, to explore possible differences in terms of the outcome measures.
Materials And Methods: Patients with single or multiple mandibular or maxillary posterior edentulism rehabilitated using extra-short 5-6 mm long implants were included.
The Study Aims: To evaluate and compare the growth of gingiva around dental implants following the use of collagen matrices and connective tissue grafts (CTG).
Materials And Methods: The study included 80 study participants, who were divided into four groups based on the type of material used to enhance gingival thickness. Two groups utilized collagen matrices, Fibro-Gide and FibroMatrix as materials, while the other two groups utilized CTG obtained from the hard palate or tubercle area of the maxilla as controls.
Craniosynostosis: Quantifying Differences in Skull Architecture.
Cleft Palate Craniofac J

Division of Plastic and Reconstructive Surgery, The Warren Alpert Medical School of Brown University, Providence, RI, USA.
Craniosynostosis, a condition marked by the premature fusion of one or more cranial sutures, exhibits diverse phenotypes. This study aims to advance the understanding of these phenotypes beyond the conventional 2-dimensional analysis by focusing on identifying indicators of increased intracranial pressure (ICP) such as bony thinning or irregularities in skull morphology. A retrospective review was conducted for all pediatric patients with midline craniosynostosis who presented to our tertiary academic center for evaluation.

Prog Orthod

Department of Orthodontics, School and Hospital of Stomatology, China Medical University, Shenyang, 110002, P.R. China.
Objective: This study aimed to evaluate the positional and morphological changes in the temporomandibular joint (TMJ) in adult patients with skeletal Class I malocclusion treated with fixed orthodontic appliances (FAs) and clear aligners (CAs), both with and without premolar extractions.
Methods: This retrospective study involved 120 adult patients divided into non-extraction and extraction groups, each further subdivided equally into those treated with FAs and CAs. Cone beam computed tomography (CBCT) was used to assess the TMJ measurements before (T0) and after treatment (T1).
The influence of prosthetic treatments and implant-supported prostheses on posterior mandibular ridge atrophy: a retrospective cohort study.
BMC Oral Health
January 2025
Division of Restorative Dentistry, Periodontology and Prosthodontics, Department of Dental Medicine and Oral Health, Medical University of Graz, Billrothgasse 4, Graz, 8010, Austria.
Aims: Bone preservation is a requirement for long-term stability of dental prostheses, which is all the more important in the posterior mandible, given the particular challenges these areas pose to prosthetic treatment. The objective was to investigate the implications of different prostheses on the atrophy of posterior alveolar bone after tooth loss.
Materials And Methods: A total of 457 treatment cases were retrieved from the medical documentation and information network.
