Evaluation of dentin features in teeth after caries removal by three techniques (chemomechanical, mechanical with a smart bur, and air-abrasion): an study.

Background: Different methods for removing dental carious lesions exist, including conventional rotary caries removal and new advanced technology like polymer-based burs, chemomechanical agents, air abrasion, and laser.

Objectives: This study shows the differences in features of dentin (smear layer, patency of dentinal tubules, surface irregularities, intertubular micro porosities, and exposed dentinal tubules) among different types of caries removal techniques.

Materials And Methods: An study was done on 60 primary molars with occlusal class I active caries.

The Potential Role of Reactive Oxygen Species Produced by Low-Density Neutrophils in Periodontitis.

Objective:  Neutrophils own an arsenal of dischargeable chemicals that enable them to handle bacterial challenges, manipulating innate immune response and actual participation in acquired immunity. The reactive oxygen species (ROS) are one of the most important chemicals that neutrophils discharge to eradicate pathogens. Despite their beneficial role, the ROS were strongly correlated to periodontal tissue destruction.

Effect of Occupational Stress on Periodontitis According to the Salivary RANKL Level Among Iraqi Employees.

Background: Findings show that periodontitis does not affect all populations; similarly, some individuals present risk conditions such as occupational stress, making them more susceptible to developing periodontitis through unhealthy habits like poor oral hygiene and immune suppression. Periodontitis triggers an inflammatory host immune response; "Receptor Activator Nuclear Factor KB ligand (RANKL)" is the primary regulator of osteoclast differentiation and activity. It was found that osteoclastic bone damage caused by periodontitis depends on the RANKL produced by osteoblastic and periodontal ligament cells.

Association Between AIM2 and Pycard Genes Polymorphisms and Susceptibility to Periodontitis with Coronary Heart Disease.

Background: Numerous genetic variations in inflammasome components are linked to prevalent disorders in the general population, including periodontitis and cardiovascular illness. Polymorphisms in the genes play a critical in the initiation and development of inflammatory diseases. The limited study on AIM2 gene variation associated with inflammatory disease and no study of PYCARD gene variation associated with inflammatory disease.

Peripheral Bone Removal versus Sequential Drilling Protocol in Dental Implant Surgery: A 5-Year Retrospective Study.

Objective:  The aim of this study was to compare the immediate success rate between peripheral bone removal (PBR) and conventional sequential drilling protocols.

Materials And Methods:  Biographic data of 130 Iraqi patients who attended a private dental implant center in Baghdad between January 7, 2018 and February 30, 2023 were collected. During this period, 198 dental implant procedures were completed.

Novel association between single-nucleotide polymorphisms of IKKβ at rs17875746 and rs12676482 and periodontitis.

Background: Single-nucleotide polymorphisms (SNPs) in the IKKβ gene have been associated with susceptibility to various inflammatory illnesses, including periodontitis.

Objectives: The aim of the present study was to investigate the association between IKKβ SNPs (at rs17875746 and rs12676482) and periodontitis in an Iraqi Arab population.

Material And Methods: In this case-control study, 94 Iraqi volunteers were split into 2 groups, with the case group including 62 periodontitis patients (37 men and 25 women) and the control group including 32 racially matched healthy people (19 men and 13 women).

The Antimicrobial Peptide LL-37 as a Predictor Biomarker for Periodontitis with the Presence and Absence of Smoking: A Case-Control Study.

Background: A major issue is finding a valid biomarker able to diagnose periodontal disease with the presence and absence of risk factors. Indeed, the association between smoking and periodontal diseases and its impact on the manifestation of antimicrobial peptides has been delineated in clinical and epidemiological investigations. The antimicrobial peptide cathelicidin (LL-37) is pivotal in preserving periodontal health.

Domains of Students' Concerns in Oral Diagnosis and Surgery Clinic.

Background: Oral diagnosis and surgery education is the main educational subject in dental schools. Due to its importance and the demand to achieve a proper level of training, dental students might have some concerns related to this subject. The study aims to investigate domains related to students' concerns in oral surgery clinics.

Comparison of Some Salivary Characteristics in Iraqi Children with Early Childhood Caries (ECC) and Children without Early Childhood Caries.

Background: Early Childhood Caries (ECC) is a unique form of caries that develops in temporary dentition. It has a multifactorial infectious disease. Saliva is one of the most important factors, which has an important protective effect against tooth decay when its multiple characteristics and functions are normal.
