Objective: A retrospective cohort study was conducted to investigate and assess possible risk factors for IOWD related to patients and surgical technique.

Methods: All patients who did not have diabetes, were not medically compromised such as patients with nutritional deficiencies or endocrine disorders, did not smoke, did not consume alcohol, and had mandibular fractures managed through open reduction internal fixation and via intraoral vestibular incision from January 2007 to December 2019, at Al-Azhar University Hospitals, in Cairo, Egypt were included in the study.

Effect of Nano-hydroxyapatite and platelet-rich fibrin covered by the amniotic membrane on osseointegration after mandibular piezoelectric ridge splitting.

Objective: This study aimed to assess the clinical and radiographic findings obtained by using amniotic membrane (AM) to cover nano-hydroxyapatite (nHA) bone grafts coated with platelet-rich fibrin (PRF) and thereby evaluate the osseointegration of posterior mandibular implants inserted simultaneously during alveolar piezoelectric ridge splitting technique (RST).

Methods: A prospective cohort study was implemented with thirty patients who had a narrow posterior mandibular alveolar ridge and required implant restoration. Patients were distributed randomly into three groups (group I treated by piezoelectric RST and immediate implant insertion, augmented by the nHA bone graft only; group II treated by piezoelectric RST augmented by nHA bone graft and covered by AM; while group III was treated by piezoelectric RST augmented with PRF and nHA graft and covered by AM).

Radiomorphometric Evaluation of the Frontal Sinus in Relation to Age and Gender in Saudi Population.

Background: Radiographs have been used for forensic identification purpose. At times when only skull remains are found and other means of identification fail, radiographs of skull may be used for identification purpose.

Aim: The objective of this study was morphometric evaluation of the frontal sinus by using digital posteroanterior skull radiograph in relation to age and gender and to establish its forensic importance.

Dynamic cyclic and torsional fatigue resistance of TruNatomy compared with different nickel-titanium rotary instruments.

This study evaluated the dynamic cyclic and torsional fatigue resistance of recently introduced TruNatomy instruments (TRN) and compare with HyFlex CM (HFC), Vortex Blue (VB) and FlexMaster (FM) instruments. Size 20, 0.04 taper of TRN, HFC, VB and FM instruments was tested for dynamic cyclic and torsional fatigue resistance.

In vitro comparison of cyclic fatigue resistance of TruNatomy in single and double curvature canals compared with different nickel-titanium rotary instruments.

Background: The purpose of this study was to compare the cyclic fatigue resistance of newly developed TruNatomy instruments (TRN) in single and double (S-shaped) curvature canals with HyFlex CM (HCM), Vortex Blue (VB) and RaCe (RC) instruments.

Methods: Size 20/.04 taper and size 25/0.

Nonsurgical Orthodontic Intervention of a Severe Class II Case Accompanied by Posterior Crossbite Using a Miniscrew-Assisted Straight Wire Technique.

Class II malocclusion in nongrowing patients is a great challenge in treatment especially if the degree of malocclusion is severe. In such cases, the use of miniscrews for orthodontic camouflage can produce results comparable to that of orthognathic surgery. This case report presents an adult patient with severe Class II malocclusion combined with bilateral posterior crossbite, deep bite, a crowded lower arch, and a history of extraction of the lower right first molar.

Impact of Removable Partial Denture Type on Patient Satisfaction and Abutment Survival Rate-RCT.

Background: Patient's satisfaction and the preservation of abutments is the most important outcomes that the clinician seeks during fabrication of any dental treatment, especially when it is concerned with removable prosthodontic rehabilitation.

Aim: The present study evaluates three different Removable Partial Denture (RPD) types restoring mandibular class II modification I edentulous cases with regards to patient's satisfaction and abutments survival.

Methods: Forty-two partially edentulous patients were divided into three groups (Group I rehabilitated with Vitallium RPD, Group II rehabilitated with Vitallium RPD where the modification area restored with the surveyed bridge, Group III rehabilitated with Thermopress RPD).
