This study investigated the effect of dentin surface treatment with the erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser on the bond strength of zirconia to dentin. Although it is well-known that resin cement (RC) provides adequate bond strength of zirconia restorations to the tooth structure, many clinicians were not convinced in bonding reliability to zirconia materials. So, they preferred cementing their crowns with glass-ionomer cement (GIC).

Methods: Sixty-four maxillary central incisors were endodontically prepared with nickel-titanium rotary instruments and randomly assigned into two groups (n=32). Roots were filled with gutta-percha using a single-cone technique in conjunction with one of the two sealers, AHP or BCS.
Aim: This study aims to describe dental treatment provided to healthy and medically compromised patients treated under general anesthesia (GA) over a four-year period.
Materials And Methods: A total of 97 patients who received dental treatment under GA at the Saint Joseph University, Lebanon, from 2016 to 2019 were included in the study. The study population was analyzed according to the patient's age, medical status, and type of treatment done accordingly.
Purpose: To evaluate the fracture resistance and failure modes of endodontically treated mandibular molars restored with different designs of inlays, onlays and endocrowns.
Materials And Methods: Extracted mandibular third molars (n = 180) were used. An access cavity was prepared on the occlusal surface of each tooth and the roots were obturated with gutta percha.
Unlabelled: Elastomeric chains are widely used by orthodontists for incisor retraction and space closure. However, force degradation and permanent deformation are expected to occur.
Objectives: The present study was designed to compare the force degradation of closed, open, grey and transparent power chains from four orthodontic companies (American orthodontics® (AO®), Dentsply®, Ormco® and Rocky Mountain Orthodontics® (RMO®)) over time.
Because of the high rate of agenesis and supernumerary teeth in orthodontic patients and the lack of studies in Lebanon that document the prevalence of those anomalies, the aim of this study was to determine the prevalence of hypodontia and supernumerary teeth in patients attending a pediatric dental office and examine the associated factors. This was a cross-sectional design study. The patients were clinically examined followed by panoramic radiograph.

Objective: Minimal invasive endodontics preserve coronal and radicular tooth structure to increase the fracture resistance of teeth. The aim of this study was to assess the influence of final preparation taper on the fracture resistance of maxillary premolars.
Materials And Methods: Sixty maxillary premolars were selected and divided into 2 groups: 30 were shaped with a final apical diameter 30 and a 4% taper and 30 with 6% taper using iRaCe instrument (FKG dentaire, Switzerland).
Background: The American Academy of Pediatrics and the American Academy of Pediatric Dentistry have recommended that the child's first dental visit should be during the child's first year of life for dental disease prevention and to decrease the invasive restorative interventions. In Lebanon, no study has been conducted to determine the age and the reasons of the first dental visit of children and who requested the first dental screening.
Objectives: To assess at what age occurred the first dental visit in a group of Lebanese children visiting a private pediatric dental clinic and to explore the reasons for their first dental consultation.
Unlabelled: Lead exposure is a global environmental problem inducing lifelong adverse health effects. Children's exposure to lead, from birth to 6 months, is typically dominated by dietary sources. The first primary mandibular molar could provide an integrated record of lead exposure.
