Factors Affecting Patients' Atttendance for Periodontal Follow-up Visits after Crown Lengthening Surgery.

Purpose: To assess adherence to follow-up maintenance visits among patients who had previously undergone crown-lengthening surgery and investigate the different factors impacting their compliance.

Materials And Methods: A total of 314 patients were identified for follow-up appointments. Based on their responses, participants were categorised into four groups: attendees, non-attendees, refusals, and unreachable.

Peri-Implant Mucosal Fenestration and Histologic Observation of Bone Xenograft Material 7-Years After Implant Installation: A Case Report.

Bone augmentation is often required before the installation of dental implants. Here, we report a case for a patient who previously received bone augmentation at the upper right jaw using a xenogenic graft, followed by successful implant installation. Seven years later, the patient presented with mucosal fenestration with bone exposure at the area and gave a history of a recent diagnosis of cutaneous lichen planus.

Maxillary root amputation: Case report with a 14-year-follow-up and updated mini review.

Root resection is performed to create a maintainable furcation area in teeth with advanced periodontitis. However, the long-term feasibility of this treatment remains controversial. We present a case in which distal root resection in a maxillary molar successfully preserved the form and function of the dentition for approximately 14 years.

Incidence of maxillary sinus septa in the saudi population.

Background: The variability in the maxillary sinus anatomy makes dental implant planning challenging. One of the anatomical landmarks that could affect the decision for implant placement around the maxillary sinus is the sinus septa. This study aimed to retrospectively determine the prevalence, anatomical distribution, and morphology of the maxillary sinus septa.

Clinical and Radiographic Peri-Implant Parameters and Whole Salivary Interleukin-1β and Interleukin-6 Levels among Type-2 Diabetic and Nondiabetic Patients with and without Peri-Implantitis.

Objective: The aim was to assess the peri-implant clinical and radiographic parameters and whole salivary levels of interleukin (IL)-1β and IL-6 among type 2 diabetic and nondiabetic patients with and without peri-implantitis.

Material And Methods: Ninety-one implants were placed in patients without type 2 diabetes mellitus (39 patients with and 52 patients without peri-implantitis; group 1). Eighty implants were placed in patients with diabetes (35 patients with and 45 patients without peri-implantitis; group 2).

Isolation of dental pulp stem cells from a single donor and characterization of their ability to differentiate after 2 years of cryopreservation.

Objectives: To investigate the viability and differentiation capacity of dental pulp stem cells (DPSCs) isolated from single donors after 2 years of cryopreservation.  

Methods: This prospective study was conducted between October 2010 and February 2014 in the Stem Unit, College of Medicine, King Saud University, Riyadh, Saudi Arabia. Seventeen teeth extracted from 11 participants were processed separately to assess the minimum tissue weight needed to yield cells for culturing in vitro.

Dental pulp stem cells. Biology and use for periodontal tissue engineering.

Inflammatory periodontal disease is a major cause of loss of tooth-supporting structures. Novel approaches for regeneration of periodontal apparatus is an area of intensive research. Periodontal tissue engineering implies the use of appropriate regenerative cells, delivered through a suitable scaffold, and guided through signaling molecules.

Osteogenic differentiation of dental pulp stem cells under the influence of three different materials.

Background: Regeneration of periodontal tissues is a major goal of periodontal therapy. Dental pulp stem cells (DPSCs) show mesenchymal cell properties with the potential for dental tissue engineering. Enamel matrix derivative (EMD) and platelet-derived growth factor (PDGF) are examples of materials that act as signaling molecules to enhance periodontal regeneration.

Congenital adrenal hyperplasia with localized aggressive periodontitis and amelogenesis imperfecta.

Congenital adrenal hyperplasia (CAH) is an inherited medical condition that implies defects in steroid biosynthesis. The dental findings of a female patient with CAH are reported. The patient suffered from severe periodontal tissue destruction, obvious enamel defects, as well as some occlusal problems.
