Evaluation of the effect of antimicrobial nanoparticles on bond strength of orthodontic adhesives: A review article
Amirhossein Mirhashemi, Leila Jazi

Year : 2021 | Volume : 18 | Issue : 1 | Page : 110
Antimicrobial nanoparticles (NPs) have various applications in different fields of dentistry. The purpose of incorporating NPs into orthodontic adhesives is to inhibit the cariogenic bacteria and reduce decalcifications around bonded orthodontic brackets. However, they may affect the physical and mechanical properties of adhesive such as shear bond strength (SBS). This review was done to answer the question whether the incorporation of antimicrobial NPs into orthodontic adhesives changes the SBS.

Evaluation of stress distribution of porous tantalum and solid titanium implant-assisted overdenture in the mandible: A finite element study
Ayshin Akbarzadeh1, Yasser Hemmati1, Fariba Saleh-Saber2
doi : 10.4103/1735-3327.332102
Year : 2021 | Volume : 18 | Issue : 1 | Page : 108
The present study aimed to evaluate the stress distribution of porous tantalum implant and titanium solid implant assisted overdenture (IAO) in mandibular bone by utilizing three-dimensional (3D) finite element (FE) analysis.
Comparison of the cleaning efficacy of XP-endo shaper and Mtwo rotary files in oval-shaped canals

Cleaning and shaping of root canals are essential steps for the success of endodontic therapy. This study compared two types of rotary files in oval-shaped root canals: XP-endo shaper (FKG, La Chaux-de- Fonds, Switzerland) and Mtwo (VDW, Germany, Munich) with regard to cleaning ability and canal preparation. Mtwo is a system of nickel–titanium files with S-shaped cross-sectional design and XP-endo shaper can change its shape according to the temperature.

Year : 2021 | Volume : 18 | Issue : 1 | Page : 105
It is difficult to perform dental procedures in autistic children, and parental involvement is necessary for successful hospital dental services. Therefore, in order to promote oral health in autistic children, this study was aimed to explore the knowledge, attitude, and performance of autistic children's parents with respect to hospital dentistry.
Frequency of caries in triangular-shaped radiolucencies on periapical radiographs of maxillary deciduous second molars
Mitra Tabari1, Mina Yazdizadeh1, Farida Abesi2, Soraya Khafri3, Javad Vaziri Dozin4
doi : 10.4103/1735-3327.332098
Year : 2021 | Volume : 18 | Issue : 1 | Page : 104
Dentists might face various artifacts (such as triangular-shaped radiolucencies [TSRs]) during the assessment of radiographs and should be able to differentiate them from caries to avoid unnecessary treatments.

Ossifying fibromas (OFs) are benign, well-demarcated lesions in the craniofacial region, particularly in the jaws, with clinical, radiographic, and histopathological similarities to other lesions, which make their diagnosis challenging. Herein, we report a case of a fibro-osseous lesion in the anterior maxilla of a 13-year-old boy, consisting of an intraosseous and an extra-osseous part, which created a diagnostic dilemma.
