DATA SOURCES: Unrestricted search of four indexed databases up to September 2022 was performed to identify randomized controlled trials (RCTs) evaluating the effect of root coverage surgery on DH frequency and/or intensity pre-surgically (baseline) and at least 3 months post-surgically. Two authors independently conducted study screening and data extraction...

A peg shaped maxillary lateral incisor, is an underdeveloped small, malformed permanent tooth erupting following a deciduous tooth has been lost. That upper lateral irregularly shaped incisor may appear solitary, on both sides of the central incisors or along with a missing lateral tooth in the contra-lateral side of the arch. Peg shaped upper lateral incisors receive a great deal of attention, play a significant role in the displayed smile, and present a treatment challenge during all stages of a patient's life...

BACKGROUND: Ectopic eruption of the permanent first molar can lead to malocclusion if left untreated. Despite several reported etiological factors and treatment options, ectopic eruption caused by an improper restoration on an adjacent tooth and a simple solution have never been documented. CASE REPORT: An 8-year-old boy presented with an entrapped ectopic permanent mandibular first molar under the poorly-adapted margin of a preformed metal crown (PMC) on the adjacent primary second molar is described...

PURPOSE: Present study aimed to assess the clinical and radiographic effect of the bone graft (BG) material (β-tricalcium phosphate + hydroxyapatite) alone and in combination with platelet rich fibrin (PRF) in intrabony defects (IBD) of periodontitis patients. METHODS: It is a 6-month randomized controlled clinical trial carried out in 42 IBDs of periodontitis (average age 40 years). IBD ≥ 3 mm along with associated probing depth of ≥ 5 mm following phase-I therapy were treated either with open flap debridement (OFD) with bone graft (β-tricalcium phosphate + hydroxyapatite- i...

OBJECTIVES: This manuscript presents a systematic review of the impact of the COVID-19 pandemic on head and neck cancer (HNC) patients. A meta-analysis was made to compare the number of treated/operated HNC patients in pre-COVID-19 era (PCE) versus COVID-19 era (CE). This investigation is based on previous reports showing a delay in the diagnosis and treatment of new cases of cancer during the pandemic. Worsening in cancer prognosis would be expected as a result of the delayed treatments...

OBJECTIVE: The present study compares interleukin 1-beta (IL-1β) and soluble urokinase plasminogen activation factor receptor (suPAR) levels in periimplant sulcular fluid (PISF) of patients with cement-retained (CR) and screw-retained (SR) implants. METHOD AND MATERIALS: Patients with CR and SR implants were encompassed. Demographic data was collected and implant-related characteristics (geometry, insertion torque, loading and retention protocol, jaw location, duration in function and depth of insertion) were retrieved from records...

With increasing age and edentulism, numerous aesthetic changes occur to the perioral region. The upper lips lose definition, flatten and lengthen, the cupid's bow is lost, and the oral commissures descend. The nasolabial folds deepen, marionette lines become prominent, vertical rhytids around the lips form, and chin rhytids form. Chronic exposure to UVA radiation from the sun can lead to photodamage, characterized by wrinkles, lentigines, actinic keratoses, and other pigment changes. In addition, edentulism leads to jaw atrophy, which often compromises soft tissue support...

OBJECTIVES: The aim of this report was to present the effectiveness of a novel augmented corticotomy performed before orthodontic treatments in the prevention of buccal alveolar dehiscence and gingival recession. METHOD AND MATERIALS: Four periodontally healthy individuals presenting crowding and thin bone morphotype in the mandibular front area were treated with a double-layer tunnel flap, piezotomy, hard- and soft tissue augmentation. Patients were divided into two groups according to the utilized graft material...

Interim rehabilitation of edentulous patients is essential in implant prosthodontics. However, surgical augmentation may be required for patients with reduced bone density, which complicates the use of an interim prosthesis. This report describes the rehabilitation of an edentulous patient with an interim maxillary overdenture retained by short implants with individual attachments during the healing period of vertical and horizontal ridge augmentation. This technique increased the stability of the interim prosthesis even with shortened flanges to eliminate any pressure on the surgical site...

METHOD AND MATERIALS: The three-arm, parallel-group, randomized controlled trial included 63 PD stage 1 and 2 patients aged ≥ 40 years and scores ≥26 in both Montreal Cognitive Assessment test and Mini-Mental State Exam. These patients were allocated to 3 OHEI groups - lectures, presentation, and demonstration...

Peripheral facial nerve palsy (PFP) is a rare occurrence after dental extraction. Early onset PFP after the procedure can be caused by trauma and/or local anesthesia, whereas delayed onset PFP has more speculative etiologies. The latter has a certain affiliation to Bell's palsy and is therefore primordially treated with corticosteroids and long-term follow-up is often warranted. This article reports a unique case of a 30-year-old woman developing a delayed onset right-sided PFP after local intraoral anesthetic injection for molar extraction...

OBJECTIVES: To assess the association between the baseline radiographic defect angle and the long-term clinical outcomes following periodontal regenerative therapy with Enamel Matrix Derivative (EMD). METHOD AND MATERIALS: Baseline peri-apical radiographs obtained from a cohort of patients treated with periodontal regenerative therapy were digitized and the radiographic angle width between the root surface and the bony wall of the adjacent intraosseous defect was calculated and reported in degrees (°)...

Implant-based rehabilitation is a clinical challenge, especially in the esthetic area. Numerous factors influence the outcome of the rehabilitation; however, the two main factors are the bone and soft-tissue deficiencies at the intended implant site. Peri-implant soft tissue complications can arise from a combination of factors that can be summarized in two categories: diagnostic errors and surgical planning management errors. Most of the complications can be corrected after each step of the treatment and even after the delivery of the prosthetic restoration with adequate soft tissue management in order to give the patient an esthetically pleasing outcome...
