“…Protaper instruments with its convex triangular cross section and reduced radial lands are more aggressive and create more debris and smear layer (31). Protaper next file system showed better debris and smear layer removal versus to protaper, because of its offset mass of rotation which allowed two pointed contacts of a file to the canal at a time that reduced the chances of compressing the debris into the root canal wall with high canal cleaning ability (32). However, difference between Protaper and Protaper next was not statistically significant.…”

Aim: The purpose of the present study was to compare the cleaning effectiveness of two reciprocating single-file systems with ProTaper Next and ProTaper Universal rotary instruments during the preparation of single-rooted extracted teeth. Methodology: Sixty freshly extracted single-rooted human teeth were randomly divided into 4 groups (n=15). In group 1, root canals were prepared with ProTaper Universal, in group 2, they were prepared with ProTaper Next, in group 3, they were prepared with WaveOne and in group 4, root canals prepared with Reciproc systems. Canals were prepared to the following apical sizes: ProTaper Universal F3, ProTaper Next X3, WaveOne Primary and Reciproc 25. The irrigant in all groups was 2ml 2.5% sodium hypochlorite (NaOCl) solution, the final irrigation after preparation all groups was 2ml NaOCl, 2ml EDTA and 2ml saline solution. The roots were split longitudinally into halves and the canals examined using a scanning electron microscope. The presence of a debris and smear layer was recorded at the coronal, middle and the apical thirds of root canals using a five-step scoring scale. Data were statistically analyzed using Kruskal-Wallis and Mann-Whitney U tests. Results: All groups showed more efficient smear layer and debris removal coronally than in the middle and apical regions, whereas the mean total debris score and the mean smear layer score in all groups were less in the WaveOne and the Reciproc groups. Conclusions: Under the conditions of this study, for root canal cleanliness Reciproc and WaveOne may be preferred rather than ProTaperUniversal and ProTaperNext.

“…Also sexual dimorphism is indicated in the timing and duration of tooth formation, with dental maturity generally being more advanced in females than in males in permanent dentition in reverse of those for the deciduous dentition [17]. If only pulp volume is measured and used as age indicator, there is a significant difference between the accuracy for males and females [117,118]. To account for this, many dental age estimation methods publish sex-specific formulae or charts.…”

“…When sex is unknown, the most accurate method is Willems followed by Demirjian and then Haavikko first premolar [76]. Additionally, sex has no statistically significant effect on age estimation, when pulp-to-tooth ratio is calculated [117,118].…”

Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. Visual, radiographic, chemical and histological techniques can be used for dental age estimation. Visual method is based on the sequence of eruption of the teeth and morphological changes that are caused due to function such as attrition, changes in color that are indicators of aging. Radiographs of the dentition can be used to determine the stage of dental development of the teeth from initial mineralization of a tooth, crown formation to root apex maturation. Histological methods require the preparation of the tissues for detailed microscopic examination. The chemical analysis of dental hard tissues determines alterations in ion levels with age, whereas the histological and chemical methods are invasive methods requiring extraction/sectioning of the tooth. In this chapter, the different techniques and considered studies were overviewed in conjunction with their advantages and disadvantages. It needs to be taken into consideration that rather than restricting on one age estimation technique, using the other available techniques additionally and performing repetitive measurements may be beneficial for accurate age estimation.

Age estimation based on pulp cavity/chamber volume of 13 types of tooth from cone beam computed tomography images

Abstract: The pulp chamber volume of the maxillary second molars has the largest correlation coefficient with age. Using multiple types of tooth may improve the accuracy of age estimation compared with only one type of tooth used.
