Effect Of Taper And Pitch On Nickle-Titanium File With Variable Cross Section To Its Cyclic Fatigue (In Silico Study), Yustika Chrysandra, Tunjung Nugraheni, Wignyo Hadriyanto

Journal of Dentistry Indonesia

The geometric design of an endodontic file includes cross-sectional shape, taper, and pitch. NiTi endodontic files of OneCurve (MicroMega) are made of two variations of cross-sectional shape, that is, double-s shaped and triple helix. Various kinds of modifications were made to increase the resistance of the NiTi endodontic files from fracture. Cyclic fatigue is the most common factor that causes a fracture of the endodontic file. Objective: The purpose of this study was to obtain a NiTi endodontic file design that has the best cyclic resistance value based on its taper size and number of pitch. Methods: This …

Mathematical Modeling For Dental Decay Prevention In Children And Adolescents, Mahdiyeh Soltaninejad

Dissertations

The high prevalence of dental caries among children and adolescents, especially those from lower socio-economic backgrounds, is a significant nationwide health concern. Early prevention, such as dental sealants and fluoride varnish (FV), is essential, but access to this care remains limited and disparate. In this research, a national dataset is utilized to assess sealants' reach and effectiveness in preventing tooth decay, particularly focusing on 2nd molars that emerge during early adolescence, a current gap in the knowledge base. FV is recommended to be delivered during medical well-child visits to children who are not seeing a dentist. Challenges and facilitators in …

School of Dentistry Faculty Publications

BACKGROUND: Determination of the eligibility of several tooth analog materials for use in crown fracture testing. METHODS: A standardized premolar crown preparation was replicated into three types of resin dies (C&B, low modulus 3D printed resin; OnX, high modulus 3D printed resin composite; and highest modulus milled resin composite). 0.8 mm zirconia crowns were bonded to the dies and the maximum fracture load of the crowns was tested. Twelve extracted human premolars were prepared to a standardized crown preparation, and duplicate dies of the prepared teeth were 3D printed out of C&B. Zirconia crowns were bonded to both the dies …

Surface Modifications Of Orthodontic Bone Screws - A Novel Approach, Sai Kalyan Menta Dr, Ravi M. S

Annual Research Symposium

Anchorage control plays a key role in the correction of malocclusion. With the advent of orthodontic bone screws, attaining absolute anchorage control has become hassle free. They have the advantages of low cost, simple surgical placement, and ease of removal; therefore, they are convenient in the treatment of various malocclusions. Although the clinical stability of bone screws is exceptionally high, stability of the bone screws is compromised by factors such as microbial contamination and morphological defects. To overcome this, surface modifications are introduced to enhance the stability of the bone screws.
