Horizontal ridge augmentation with particulate cortico-cancellous freeze-dried bone allograft alone or combined with injectable-platelet rich fibrin in a randomized clinical trial.

Objectives: The objective of this study is to assess the effectiveness of horizontal ridge augmentation using FDBA in combination with injectable-platelet rich fibrin (i-PRF) versus FDBA alone. To fulfill this aim, the radiographic and histomorphometric outcomes are compared.

Method: The study involved 41 patients who had horizontal alveolar ridge defects categorized as either B (2.

A prospective cohort study protocol: monitoring and surveillance of adverse events following heterologous booster doses of Oxford AstraZeneca COVID-19 vaccine in previous recipients of two doses of Sinopharm or Sputnik V vaccines in Iran.

Background: Regarding the paucity of evidence on the side effects of the booster dose of Oxford AstraZeneca vaccine in vaccinated people with Sinopharm or Sputnik V, we aimed to set up a cohort event monitoring (CEM) study to capture adverse events occurring in individuals who will receive the booster doses of AstraZeneca (either the first or second booster dose) following being vaccinated with Sinopharm or sputnik V vaccines in Iran.

Methods: The present study is an active COVID-19 vaccine safety surveillance through an observational prospective cohort study that will be conducted in vaccination centers in Iran. The study will be conducted in twelve provinces of Iran.

Adherence to diet with higher dietary diabetes risk reduction score is associated with reduced risk of type 2 diabetes incident in Iranian adults.

Background: The Dietary diabetes risk reduction score (DDRRS) has recently been considered by researchers as a diet quality index to predict the risk of chronic diseases, such as type 2 diabetes (T2D). In this study, we aimed to assess the association of DDRRS with T2D risk in Iranian adults.

Methods: Subjects aged ≥ 40 years without T2D (n = 2081) were selected for the current study from participants of the Tehran Lipid and Glucose Study (2009-2011) and followed for a mean of 6.

A Survey of Oral and Maxillofacial Biopsies Over a 23-year Period in the Southeast of Iran.

Statement Of The Problem: The prevalence of oral and maxillofacial lesions differs in various populations and is an important concern for health care providers.

Purpose: The present study aimed to evaluate the relative frequency and distribution of oral and maxillofacial lesions in patients referred to the Department of Oral and Maxillofacial Pathology, Kerman Faculty of Dentistry in southeast Iran.

Materials And Method: In the present retrospective study, the collected data consisted of age, gender, lesion location, and the clinical and histopathological diagnoses of all the biopsy samples diagnosed in 23 years (1997-2020).

Global prevalence of oral pigmentation and its related factors: a systematic review and meta-analysis.

Background: Oral pigmentation is due to the accumulation of one or more pigments in tissues, causing changes in the color of the oral mucosal surfaces. Understanding the exact global prevalence of oral pigmentation and its associated factors helps researchers make the proper interventions at the right time; in this respect, the objective of the present systematic review and meta-analysis was to determine the global prevalence of oral pigmentation and its related factors.

Method: A systematic review and meta- analysis were conducted using the following databases: Magiran, SID, Scopus, Embase, PubMed, Web of Science (WoS), and Google Scholar.

Radiological and histological evaluation of horizontal ridge augmentation using corticocancellous freeze-dried bone allograft with and without autogenous bone: A randomized controlled clinical trial.

Purpose: The purpose of this study was radiological and histological evaluation of horizontal ridge augmentation using corticocancellous freeze-dried bone allograft (FDBA) with and without autogenous bone (AB).

Materials And Methods: The present research was conducted on 42 patients (27 females and 15 males) with insufficient width of edentulous ridge. The patients were randomly assigned into two groups, FDBA alone + collagen membrane (n = 21) and the combined FDBA and AB + collagen membrane (n = 21).

Orthodontic Treatment Need and Complexity among 13-15 Year-Old Schoolchildren in Kerman, Iran.

Statement Of The Problem: Effective and informed planning for orthodontic services in any population requires assessment of the orthodontic treatment need and complexity.

Purpose: The present cross-sectional study was conducted to assess these parameters using index of complexity, outcome, and need (ICON) in an Iranian schoolchildren population.

Materials And Method: In total, 600 randomly selected individuals (300 girls, 300 boys; aged 13-15 years) participated in this study.

Effects of interfacial interactions and interpenetrating brushes on the electrospinning of cellulose nanocrystals-polystyrene fibers.

This study investigated the electrospinning of polystyrene solutions using added unmodified and modified (with grafted nitrobenzene and trifluoromethyl benzene functionalities and polystyrene brushes) cellulose nanocrystals (CNCs). A strong correlation existed between the formation of beads on the fibers and the degree of dispersion of CNC particles in the electrospinning mixtures. Agglomerates of CNC particles always concentrated in the form of beads.

A Survey of Knowledge, Attitude and Practice of Iranian Dentists and Pedodontists in Relation to Child Abuse.

Statement Of The Problem: Since almost half of the child abuse cases affect the head and neck region, dentists have an important role in the diagnosis and report of oral and dental aspects of child abuse cases.

Purpose: The objective of the current study was to evaluate the knowledge, attitude and practice of the general dentists and pedodontists regarding child abuse and child neglect.

Materials And Method: This cross-sectional study was carried out on the participants of the 12 congress of pedodontists of Iran.

Measurement of the levels anxiety, self-perception of preparation and expectations for success using an objective structured clinical examination, a written examination, and a preclinical preparation test in Kerman dental students.

Statement Of The Problem: Examinations have an important role in evaluating students' learning outcomes and their mastery of a subject. Passing or failing an examination can have far-reaching consequences for the students. Therefore, it is not surprising that international studies consistently show that dental students report examinations and grades among the highest ranking stressors in dental schools.

Peripheral Ameloblastic Fibroma: Report of a Rare Case.

Ameloblastic fibroma is a rare mixed odontogenic tumor mostly occurring in the posterior region of the mandible. The peripheral variant is very rare and to the best of our knowledge, only three cases have been reported in the English literature. In this report, we describe a case of peripheral ameloblastic fibroma in a 54-year-old woman with two years of follow-up.

Peripheral Primitive Neuroectodermal Tumor (pPNET) of the Parotid: Report of a Rare Case.

Primitive neuroectodermal tumors (PNETs) are a family of highly malignant soft tissue neoplasms mostly occurring in children and young adults. PNETs usually develop in the thoracopulmonary region, abdomen, pelvis, and rarely in the head and neck region. Here, a case of PNET located in the parotid gland is reported.

Study of Epstein-Barr virus expression in Burkitt's lymphoma by polymerase chain reaction and in situ hybridization: A study in Iran.

Background: The association of Epstein-Barr virus (EBV) with Burkitt's lymphoma (BL) is variable in different geographic regions. In developing countries, the association of EBV with BL is regarded to be of an endemic-type in equatorial Africa (> 95%) and sporadic-type in the developed countries (15-30%). The purpose of this study is to assess the frequency of EBV infection in BL, in Iran.

Materials And Methods: In the present experimental study, the water in high-speed handpieces and air/water syringes of 35 dental units in a dental school was investigated microbiologically.

Ewing's sarcoma in mandibular similar to dental abscess.

Ewing's sarcoma is a rare malignant neoplasm that comprises approximately 4-6% of primary bone tumors. In most cases, femur and pelvis are affected, and less commonly the head and neck areas (in the jaws, usually the mandible). These tumors have been reported more frequently in males, mostly aged 5-20 years old.
