Oral submucous fibrosis (OSF) is characterized by excessive fibrosis of submucosa. The degree of vascularity in OSF has always been a matter of debate. Angiogenesis is the key mechanism involved in regeneration and repair. It also plays an important role in various pathologic conditions. Angiogenesis may contribute to the progression of fibrosis in fibrotic disorders. Inhibition of pathological angiogenesis is considered to be a new strategy for the treatment of various fibrotic disorders. In OSF, angiogenesis can be related to progression fibrosis...

INTRODUCTION: Parental presence/absence in the dental operatory (also called: Parent-in-parent-out technique) is an extremely controversial aspect of the nonpharmacological BMTs. Historically, dentists used to exclude parents from dental operatory to avoid their interference with the dentist's aptitude to build a rapport and relationship with the child, hence increasing the child management problems by disrupting treatment and making the dentist unfocused and uncomfortable. AIM: The purpose of this article is to review and emphasize on the importance of parental presence/absence in the dental operatory, especially in a certain age group, as a behavior management technique (BMT) in pediatric dentistry, and to present a modified view of this technique...

BACKGROUND: Root canal anatomy is a complex entity. The main objective of root canal treatment is to get rid of the infection and have a good apical and coronal seal with an appropriate filling. Inability to achieve thorough cleaning and shaping followed by three-dimensional obturation of the root canal system usually causes root canal treatment failure. For this reason, clinicians should be aware of these anatomical variations to achieve successful treatment. AIM: The aim of this article is to report on the successful treatment and follow-up of mandibular first molar with additional middle mesial (MM) and middle distal (MD) canals...

INTRODUCTION: Edentulism is one of the debilitating states affecting a significant portion of the geriatric population. It is often considered as the ultimate marker for predicting the pressure and burden on oral health. Respiration is also a routine vital function running continuously through the human body and most commonly assessed by a spirometer. Hence, we planned the present study to assess the impact of complete dentures on the functioning of the respiratory system. MATERIALS AND METHODS: In the present study, a spirometric assessment of the effect of complete dentures on respiratory performance was done...

INTRODUCTION: Both periodontitis and type II diabetes mellitus (T2DM) are common diseases with a multifactorial etiology and have influence of cytokines in their pathogenesis and thus may also influence each other. In recent times, more attention has been given to understanding the influences of these inflammatory cytokines which are a main part of oral chronic inflammation on systemic health of the individuals. Therefore, the aim of this study was to evaluate the plasma cytokine levels, specifically tumor necrosis factor-a (TNF-a), interleukin (IL)-6, and IL-4, in chronic periodontitis patients and T2DM patients, so as to investigate the influence of chronic periodontitis in systemic inflammation associated with diabetes mellitus...

AIM: The aim of this study was to evaluate the effect of different surface treatments on roughness, grain size, and phase transformation of presintered zirconia. MATERIALS AND METHODS: Surface treatments included airborne particle abrasion (APA) before and after sintering with different particles shape, size, and pressure (50 μm Al2O3, 50 μm glass beads, and ceramic powder). Thirty-five square-shaped presin-tered yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramic slabs (Zenostar ZR bridge, Wieland) were prepared (4 mm height × 10 mm width × 10 mm length) and polished with silicon carbide grit papers #800, 1000, 1200, 1500, and 2000 to ensure identical initial roughness...

AIM: This in vitro study evaluated the resistance form of die preparations for all ceramic restorations and, thereby, explored the concept of effective taper and its correlation between the ideal in theory and actual in the clinical situation by analyzing the digital images of the die preparations. MATERIALS AND METHODS: Scanned digital images of 114 die preparations for all ceramic restorations (n = 114) were collected from a dental laboratory. All the images were also analyzed digitally using Adobe Photoshop® software to analyze the degree of taper (angle of convergence) of each preparation and then applied the Zuckerman's circle, and the Lewis perpendicular methods were used to measure the resistance form...

AIM: The most common fungal infection among human population is candidiasis, the etiology of which is mostly Candida albicans. As a result of a disrupted balance of the normal flora or a compromised immune system, Candida species can become pathogenic. Various in vitro surveys have shown that glucose intake is a promoter of C. albicans growth, whereas in vivo studies have found that xylitol can decrease the risk of candidiasis and angular cheilitis. Hence, we aimed to evaluate for the first time the inhibitory effects of xylitol on C...
