Gummy Smile Management Using Diode Laser Gingivectomy Versus Botulinum Toxin Injection - A Prospective Study.

Introduction: Gummy smile (GS) is a nonesthetic condition that affects the confidence of many young people. The present study aimed to compare the results of two approaches used in the management of GS in a group of Egyptian females.

Materials And Methods: This comparative cohort study included 24 female patients aged 25-35 years, divided into two groups.

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).

Cortical lag screw fixation for the management of mandibular injuries.

Objectives: Here, we present cases of mandibular fracture that were managed with the cortical lag screw fixation technique (CLSFT) in order to critically evaluate technique indications and limitations of application at various fracture sites.

Materials And Methods: This was a retrospective cohort study. The study sample was composed of patients suffering from mandibular fractures that were treated by the CLSFT.

Stabilization of anterior mandibular fracture using different osteosynthesis devices: perioperative clinical notes.

Purpose: There is still no definitive consensus about the ideal technique in the treatment of anterior mandibular fractures. Therefore, this study aimed to determine clinical and radiographic outcomes of four different internal fixation devices used for this type of fractures.

Methods: This was a cohort study that included 64 fracture cases.

Extraoral Versus Intraoral Botulinum Toxin Type A Injection for Management of Temporomandibular Joint Disc Displacement With Reduction.

: The present study was conducted to compare between extraoral and intraoral approach for botulinum toxin type A (BTX-A) injection into the lateral pterygoid muscle (LPM) in patients suffering from anterior disc displacement with reduction (ADDWR).Fourteen patients suffering from ADDWR were included in this prospective cohort study. Patients were enrolled randomly into 2 groups according to injection approach; where extraoral used in group I, while intraoral approach used in group II.

Does Surgical Release of TMJ Bony Ankylosis Increase the Risk of Trigeminocardiac Reflex? A Retrospective Cohort Study.

Purpose: The exact frequency of the trigeminocardiac (TGC) reflex in temporomandibular joint (TMJ) surgery is still controversial. The purpose of the present report was to estimate the frequency of and identify the risk factors for TGC reflex among patients undergoing operative management of TMJ ankyloses.

Patients And Methods: A retrospective cohort study was conducted of patients who had undergone gap arthroplasty for TMJ ankyloses at Al-Azhar University Hospital, Cairo, Egypt, from 2001 to 2015.
