Implant Health in Treated Periodontitis Patients: A Systematic Review and Meta-Analysis.

Background: The aim of this meta-analysis was to evaluate the role of a history of periodontitis on implant failure. The two main judgment criteria studied are peri-implantitis and the survival rate. The two secondary judgment criteria studied are the mean pocket depth and the mean peri-implant bone loss.

Comparing intraosseous computerized anaesthesia with inferior alveolar nerve block in the treatment of symptomatic irreversible pulpitis: A randomized controlled trial.

Aim: The aim of this study was to compare the cardiovascular effects [heart rate, oxygen saturation (SpO ) systolic and diastolic blood pressure] and the anaesthetic efficacy of intraosseous computerized anaesthesia (ICA) versus inferior alveolar nerve block (IANB) in Symptomatic irreversible pulpitis (SIP).

Methodology: The study protocol was registered with ClinicalTrials.gov (NCT03802305).

Effect of Reinforced Oral Hygiene on Periodontally Healthy Dental Students: A Four-year Follow-up Clinical Trial.

Purpose: In periodontally healthy individuals, mean crevicular depth ranges from 1 to 3 mm. This depth threshold has been used as an indicator to differentiate a physiological dentoalveolar sulcus from a periodontal pocket needing further treatment. Because many studies have shown the important contribution of oral hygiene status to periodontal health, the purpose of this study was to explore the clinical effect of reinforced oral hygiene on the periodontal status of periodontitis-free dental students.

Prevalence of dental anomalies in French orthodontic patients: A retrospective study.

Objectives: To investigate the prevalence and gender distributions of dental anomalies in French orthodontic patients.

Material And Methods: A retrospective review of the dental files of orthodontic patients was conducted to investigate the frequencies of dental anomalies. Pretreatment intraoral photographs and panoramic radiographs were analyzed.

Bioactive materials in endodontics.

Endodontic treatment in dentistry is a delicate procedure and many treatment attempts fail. Despite constant development of new root canal filling techniques, the clinician is confronted with both a complex root canal system and the use of filling materials that are harmful for periapical tissues. This paper evaluates reported studies on biomaterials used in endodontics, including calcium hydroxide, mineral trioxide aggregate, calcium phosphate ceramics and calcium phosphate cements.

Osteoblastic cell behaviour on different titanium implant surfaces.

The osseointegration of oral implants is related to the early interactions between osteoblastic cells and titanium surfaces. The behaviour of osteoblastic MC3T3-E1 cells was compared on four different titanium surfaces: mirror-polished (Smooth-Ti), alumina grit-blasted (Alumina-Ti) or biphasic calcium phosphate ceramic grit-blasted (BCP-Ti) and a commercially available implant surface (SLA). Scanning electron microscopy and profilometry showed distinct microtopographies.

Small-animal models for testing macroporous ceramic bone substitutes.

The aim of this study was to compare the bone colonization of a macroporous biphasic calcium phosphate (MBCP) ceramic in different sites (femur, tibia, and calvaria) in two animal species (rats and rabbits). A critical size defect model was used in all cases with implantation for 21 days. Bone colonization in the empty and MBCP-filled defects was measured with the use of backscattered electron microscopy (BSEM).

Microleakage of class V composite restorations following Er:YAG and Nd:YAP laser irradiation compared to acid-etch: an In vitro study.

This study compared microleakage at enamel/composite and dentine/composite interfaces following Er:YAG laser, Nd:YAP laser, or acid-etch preparation. Class V cavities produced on the lingual and buccal surfaces of 20 extracted carie- and restoration-free human teeth were randomly assigned to four groups of 10 cavities. Teeth were treated with 37% phosphoric acid and primer (group 1), irradiated with an Er:YAG laser (group 2) or an Nd:YAP laser (group 3), or served as controls (group 4).
