Objective: The objective of this study was to evaluate the microanalysis of various elements, and assess the surface characteristics of progressive periodontally diseased roots in comparison to sound root surface. Materials and Methods: 50 teeth were collected, 25 teeth from patients have progressive periodontitis, and 25 teeth from healthy patients. Measurements of probing depth and clinical a...

Age at first reproduction (AFR) has been difficult to quantify in mammals, as the most commonly used methods require reproductive tracts or direct observations. However, work in several large mammal species suggests that the width of cementum light bands in teeth decline once females begin to reproduce, suggesting that teeth structures might provide a new tool to examine AFR. To determine if ch...

1 attachment, which is lost during disease. This type of regeneration is described by the term 'New attachment'. New attachment is the embedding of new periodontal ligament fibres on to new cementum previously denuded by the periodontal disease. Factors interfering with new attachment are plaque, calculus, infected cementum and alterations in mineral density and composition of root. These obsta...

objectives: scaling and root planing (srp) is one of the most commonly used procedures during periodontal treatment. the aim of this study was to evaluate the root surface roughness after srp with erbium: yttrium aluminum garnet (er:yag) laser compared to ultrasonic and hand instruments.   materials and methods: in this experimental study, 56 extracted sound single-rooted teeth with moderate le...

Fluorosis is one of the factors that may bring about mineralization changes in teeth. Routine treatment of root biomodification is commonly followed during periodontal therapy. The purpose of the present study is to compare and evaluate the root surface changes in fluorosed and nonfluorosed teeth subsequent to the application of Tetracycline, EDTA, and Citric acid. Both fluorosed and nonfluoros...

The present study used 127 extracted teeth from people aged 16 to 90 years old. The aim of this research was to verify the reliability of the method using a single dental parameter based on the correlation of the radicular cementum thickness and the chronological age of the subject. The thickness was measured both on the lingual side and on the vestibular side of the tooth, at two different lev...

The purpose of this study was to determine the effect of calcium sulfate (CS) on cementum deposition and osseous healing after periradicular surgery. The root canals of 24 mandibular premolars in four 2-yr-old beagle dogs were endodontically treated, followed 2 weeks later by periradicular surgery. Mineral trioxide aggregate (MTA) was used as root-end-filling material. The right or left side wa...
