Incremental Banding in Dental Cementum: Methods of Preparation for Teeth from Archaeological Sites and for Modern Comparative Specimens
نویسندگان
چکیده
Analysis of incremental banding in dental cementum is a well-established means of determining the age and season of death of wild mammals. The dental cementum of domesticated mammals likewise can indicate age and season of death. Methods of preparation applicable to archaeological teeth differ from those used for modern specimens, however, and this paper describes two methods that have given excellent imaging on teeth of 8os taurus; one for modern teeth and the other for teeth from archaeological sites.

This paper outlines the first methodology for recording dental enamel hypoplasia in the highcrowned dentition of modern and archaeological caprine teeth. The method has been developed and trialed on five caprine populations from Orkney (UK); two modern populations (Shetland and North Ronaldsay breeds) and three Neolithic assemblages from the archaeological sites of Knap of Howar, Skara Brae and...
متن کاملComparative Evaluation of microleakage of Bulk-fill and Posterior Composite Resins Using the Incremental Technique and a Liner in Cl II Restorations
Background and Aim: In recent years there has been a surge in the use of tooth-colored restorations. However, the polymerization shrinkage of these materials can form gaps, resulting in microleakage. This study aimed to compare microleakage by using different materials and techniques. Materials and Methods: In this experimental study, Cl II cavities were prepared on the mesial surfaces of 60 s...

The aim of the present study was the histological evaluation of Enamel Matrix Derivative (EMD) effectiveness for regeneration of periodontal defects. EMD activates cementum synthesis, PDL and bone during the maturation stage of follicole. In this research, EMD was used in surgical defects of premolar teeth in four adult sheep. Muccoperiosteal flap was reflected in buccal site of teeth. The bucc...
متن کاملEffect of Different Enamel Preparation Methods on Microleakage of Fissure Sealant: An In Vitro Study
Objective: Lack of a dental material with optimal adhesion and sealability is an important challenge in modern dentistry leading to marginal leakage. There are controversies on the necessity of enamel preparation in pit and fissure sealant therapy and its effect on decreasing the microleakage therefore, the present in vitro study aimed to assess the amount of microleakage with and without ename...
متن کاملBacterial Leakage Assessment for Different Types of Resin-Based Dental Restorations Applied Using Various Placement Methods
Introduction: Although composite resins have improved greatly since their introduction, microleakage is one of the most frequently encountered problems. This study compared the effects of different monomer systems and layering techniques on the bacterial leakage of Cl I composite resin restorations. Methods: Eighty-two sound human third molars were used. The teeth were randomly divided into six...
