introduction: permanent first molar is the most important unit in the chewing system. ear-ly loss of first molars can significantly reduce chewing efficiency, increase overbite, lead to premature eruption of the permanent second and third molars, and displacement of adjacent teeth. the purpose of this study was to determine the associated factors of permanent first molar caries in 7-9 years old...

This paper investigates the performance of wavelet OFDM signals over a wireless communications link. The scheme is shown to be generally similar to Fourier based OFDM, but with some additional features, and improved characteristics. The sensitivity of both schemes to the nonlinear amplification in the transmitter is compared by monitoring the time domain output data and the adjacent channel pow...

Objective: This study was designed to compare the relative efficiency of GC, Tooth Mousse, which contains 10% ACP-CPP and GC Tooth Mousse Plus which contains amorphous calcium phosphate casein phosphopeptide (ACP-CPP) with sodium fluoride 0.2% w/w (900 ppm) to inhibit enamel demineralization adjacent to orthodontic brackets in vitro. Materials and methods: Forty-five non-carious, human maxillar...

Background: Certain cases such as anterior cross bites require a different aesthetic removable denture technique from the conventional denture. Purpose: To provide an overview of case about making acrylic resin partial dentures for tooth replacement in bite. Case analysis: The study examined working model with maxillary and mandibular bite cases. Result: arrangement artificial teeth was carried...

Fixed Dental Prosthesis is a treatment modality to replace the missing tooth by utilizing adjacent teeth as abutments. The health, periodontal surface area, crown root ratio and other parameters govern condition of abutment. examination these clinical radiographic determine its usage abutments support retain prosthesis. Adjunctive therapy like lengthening, foundation restorations others can be ...

Fusion and talon cusps are rare developmental dental anomalies affecting both primary and permanent dentitions. Talon cusps normally occur on the palatal surface of permanent maxillary incisors, while fused teeth are more common in the primary anterior dentition. An understanding of these dental anomalies and their associated problems are important to provide prophylactic measures, thereby prev...
