Endodontic access cavities: Fears and difficulties of Moroccan dental students related to teachers, self-confidence and technical protocol.

Fears and difficulties of Moroccan dental students regarding endodontic access cavity were evaluated among 3 items: (i) teachers, (ii) student confidence and (iii) access cavity protocol. A three Likert scale was used to rate 24 statements. Specific scores between 1 and 3 and mean scores between 0 and 1 were used to assess statements and items, respectively.

Association between Periodontitis and Pulp Calcifications: Radiological Study.

Objective: The presence of intrapulpal calcifications is one of the effects reported as a consequence of periodontal pathology. Although the impact of the pulp pathology on the periodontium is obvious, the contrary remains unclear and controversial. This study was conducted in order to better understand this fact and establish a potential association between periodontitis and intrapulpal calcifications and then to determine the factors associated with their occurrence.

Root Microcracks Formation during Root Canal Instrumentation Using Reciprocating and Rotary Files.

Aim And Objective: The aim of this study was to compare the formation of dentinal cracks with nickel-titanium (NiTi) instruments working in continuous rotation and reciprocating motion.

Materials And Methods: One hundred sixty extracted human mandibular first molars were selected for the study. The mesial roots were resected and mounted in resin blocks with simulated periodontal ligaments.

Prevalence and risk factors of Apical periodontitis in endodontically treated teeth: cross-sectional study in an Adult Moroccan subpopulation.

Background: The present study aimed at investigating the prevalence of Apical periodontitis in a Moroccan Adult subpopulation with a non-surgical root canal treatment and to assess associated risk factors including endodontic treatment quality, periodontal health status, coronal restoration cavity design and quality.

Methods: A total of 358 endodontically treated teeth were evaluated after more than 1-year period in a Moroccan subpopulation according to predetermined criteria. Studied parameters were assessed clinically and radiographically.

Effect of Vital Bleaching on Micromorphology of Enamel Surface: an in Vitro Study.

Objectives: The aims of this in vitro study was to investigate the effects of bleaching agents commonly used in micromorphology of the enamel surface and to assess the effect of concentration and of adding fluoride in the bleaching agents.

Methods: Sixty freshly extracted intact teeth were stored in distilled water. One half of each tooth was served as control, the other part was treated with bleaching agent.

Repair of untreated horizontal root fractures: two case reports.

To present two cases of root fractures which have healed spontaneously without any treatment? This article describes two untreated horizontal root fracture of the maxillary incisors. The fractured teeth were without any sign or symptom, and tested as vital to thermal and electric pulp test. These fractures were discovered during a routine full-mouth radiographic examination.
