The coronal-radicular reconstruction is a restoration that involves both the coronal part and the root part of the tooth. The objective of this study was to evaluate the clinical aspects of anterior teeth before performing corono-radicular reconstruction by inclay-core. This was a descriptive cross-sectional study for analytical purposes with prospective data collection at the fixed prosthesis department of the CHU-CNOS over a period of six (6) months from (June 2019 to December 2019). The study population was made up of patients who underwent corono-radicular reconstruction (CPR) on anterior teeth by inlay core in the fixed prosthesis department of the CHU-CNOS. The patients were submitted to a questionnaire relating to general information, the reason for consultation, the oral examination, the type of coronal-radicular reconstruction. In this study, the female sex was the most represented with 61.40% of cases and a sex ratio of 0.62 in favor of women. Dental caries was the most represented pathology, 47.14% of cases. Retro-alveolar radiography was done in the vast majority of patients, ie 91.42% of cases. Aesthetics was the most represented reason for consultation with 95.70% of cases. More than three quarters (80%) of coronal-radicular reconstructions by inlay-core on anterior teeth were performed in the maxilla. All the walls were dilapidated in more than three-quarters of the cases, i.e. 77.15%. Corono-radicular reconstruction was performed to serve as a bridge pillar in 58.30% of cases. In our study, the mechanical principles of reconstitution were good in 91.40% retention and 94.30% stabilization. Lift was also good at 54.3%. The quality of these principles depends on the clinical stage (preparation) and the technical design in the laboratory. This prosthetic element must meet several objectives, hence the need for multidisciplinary care. Efforts must be made at all levels for prosthetic rehabilitation, especially in anterior relief.

Introduction: Dental practitioners with limited training in gestational medicine may be cautious to treat their pregnant patients. Endodontic treatment requires the use of medications including analgesics as well as antibiotics. Because of a concern of harming either mother or unborn child, some dentists may hold back care or medications from their patients, unintentionally causing harm. Materials and methods: This is a cross sectional study conducted among the dental professionals and interns of Riyadh using an online survey. 504 dentists and interns were used in this study and were contacted using social media. Results: 14.3% participants were not certain whether to take full mouth radiograph for pregnant patients or not, 36.5% often used local anesthesia without epinephrine and 23.4% never prescribed antibiotics such as amoxicillin or clindamycin. Conclusion: Overall knowledge of dental practitioners regarding the endodontic therapy of pregnant patients is not satisfactory.

The cuspal deflection of different composite resin restorations cured with different systems and restoring different cavity dimensions were investigated using a total 60 freshly extracted human maxillary premolars. These teeth were divided into three main equal groups, based upon the tested restorative materials. Group (I) used T-Econpm Plus, Group (A1) (II) used Filtek Z250 XT (A2), and Group (III) used Filtek P90 (A3). Each group was subdivided into two subgroups based upon the prepared cavity dimensions. Each subgroup was further subdivided into two groups whether cured with Halogen (C1), or LED (C2). MOD cavity with two different dimensions, each restorative material was packed according to the manufacturer's instructions and cured. Dye penetration technique was used and specimens were sectioned in mesiodistal direction and examined by stereomicroscope. Collected data was statistically analyzed. The result showed T-Econom plus had statistically significant higher microleakage value, while Filtek P90 had statistically significant lower microleakage value. There was no statistically significant difference between groups cured with Halogen and LED. It can be concluded that silorane based composite, LED curing system, and smaller cavity dimension could significantly decreased cuspal deflection.
