Cross-Sectional Survey to Assess Dental Students' Perception of the Utilization of a Case Difficulty Assessment Form during Various Stages of Root Canal Therapy.

Background: Several endodontic difficulty assessment forms are available to help dental students and general dentists estimate the difficulty of the case before initiating the endodontic treatment.

Objectives: This study aimed to assess if the American Association of Endodontics (AAE) case difficulty assessment form affects the dental student's perception of the difficulty encountered while performing root canal treatment (RCT).

Materials And Methods: This was a cross-sectional online survey.

Maxillary root amputation: Case report with a 14-year-follow-up and updated mini review.

Root resection is performed to create a maintainable furcation area in teeth with advanced periodontitis. However, the long-term feasibility of this treatment remains controversial. We present a case in which distal root resection in a maxillary molar successfully preserved the form and function of the dentition for approximately 14 years.

Particulate bone grafting with a resorbable collagen membrane and horizontal alveolar ridge augmentation with tenting screws in dental implant placement: A case report.

Key Clinical Message: We used a mixture of particulate bone grafts (xenografts/allografts) with tenting screws to prevent membrane collapse and covered the graft with a resorbable collagen membrane to guide bone regeneration. This strategy can exclude the need for additional procedures, such as non-resorbable membranes and major block grafting surgeries. Although the initial outcomes are promising, continuous follow-up is required to examine the stability of the newly regenerated bone and the long-term success of the implant.

Physicians' Examination and Referral Practices on Orthodontic Problems Among 6-12-Year-Old Children in Saudi Arabia.

Use of temporary abutment to assess implant osseointegration before final impression: A case report.

In implant dentistry, a temporary abutment, either plastic or metal, also called an implant cylinder, is used to construct a provisional restoration. This provisional restoration can be cemented on or integrated with a temporary abutment for a screw-retained prosthesis. It can be further used as a diagnostic tool to evaluate esthetics and promote tissue healing around implants.

Assessment of Tumor Angiogenesis by Expression of CD 105 in Ameloblastoma, Odontogenic Keratocyst and Central Giant Cell Lesion.

Background: Angiogenesis is critical for tumor growth and reflects the aggressive behavior of invasive odontogenic lesions [like Ameloblastoma (AM), Odontogenic Keratocyst (OKC) and Central giant cell lesion (CGCL)]. Mean vascular density (MVD) shows the angiogenic potential and CD105 is an ideal endothelial biomarker due to its specificity to new blood vessels for MVD detection. The aim of the study was to compare the MVD (angiogenic potential) among AM, OKC and CGCL in comparison to Pyogenic Granuloma (PG) using CD105 biomarker.

Effects and Effectiveness of Cavity Disinfectants in Operative Dentistry: A Literature Review.

The degree of success in the elimination of bacteria during cavity preparation and prior to the insertion of a restoration may increase the longevity of the restoration and therefore the success of the restorative procedure. The complete eradication of bacteria in a caries-affected tooth, during cavity preparation, is considered a difficult clinical task. In addition to weakening the tooth structure, attempts to excavate extensive carious tissue completely, by only mechanical procedures, may affect the vitality of the pulp.
