Morphometric analysis of pulp size in maxillary permanent central incisors correlated with age: An indirect digital study

Abstract

Context:Teeth are hardest part of the body and are least affected by the taphonomic process. They are considered as one of the reliable methods of identification of a person in forensic sciences.Aim:The aim of the following study is to establish morphometeric measurements by AutoCad 2009 (Autodesk, Inc) of permanent maxillary central incisors in different age groups of Udaipur population.Setting and Design:Hospital-based descriptive cross-sectional study carried out in Udaipur.Materials and Methods:A study was carried out on 308 subjects of both genders with the age range of 9-68 years. Standardized intra-oral radiographs were made by paralleling technique and processed. The radiographs were scanned and the obtained images were standardized to the actual size of radiographic film. This was followed by measuring them using software AutoCad 2009.Statistical Analysis Used:F-test, post-hoc test, Pearson's correlation test.Results:For left maxillary central incisor, the total pulp area was found to be of 38.41 ± 12.88 mm and 14.32 ± 7.04 mm respectively. For right maxillary central incisor, the total pulp size was 38.39 ± 14.95 mm and 12.35 ± 5 mm respectively. Males (32.50, 32.87 mm2) had more pulp area when compared with females (28.82, 30.05 mm2).Conclusion:There was a decrease in total pulp area with increasing age which may be attributed to secondary dentin formation.

The Effect of Low Level Laser Therapy on Direct Pulp Capping in Dogs

“…1 The DPC technique is an effort to maintain the vitality of dental pulp following exposure. In this method, the volume of the remaining dental pulp is greater than that of the other vital pulp therapy modalities.…”

“…The continuity and morphology of the dentinal bridge could be considered as a sign of successful pulp healing. 1 Dentinal bridge formation was observed in 100% of the specimens in groups 1 to 3 and 80% of the specimens in groups 4 and 5. However, in groups 1 to 3, complete bridge formation was observed in most of the specimens, whereas in groups 4 and 5, moderate contact of the capping material with the dental pulp was more frequent.…”

“…It has been demonstrated that the use of MTA can lead to an increased rate of cell proliferation and the induction of homogenous calcified bridge underneath the exposed pulp tissue. 1 Low level laser therapy (LLLT) has been extensively used in medicine and dentistry due to its anti-inflammatory, analgesic and biostimulative effects and its great benefits in accelerating the wound healing process. [5][6][7][8][9][10] These excellent properties suggest that LLLT could play a great role in the success of DPC treatment by promoting hard tissue formation and accelerating the inflammatory process in damaged pulp tissues.…”

Identifying missing people: the contribution of forensic dentistry and DNA

“…It should be noted that, despite the current literature shows the existence of advanced technologies such as three-dimensional (3D) records of palatal roughness 18 , microscopic analysis of incremental lines of dental cement 19 and the use of softwares for morphometric measurements of dental pulps 20 , and a careful forensic dental examination associated with previous data in dental records, are sufficient to contemplate, with precision and rapidity, the success of the identification procedures, without need of further tests for human identification 13 .…”

Peer Review #2 of "In vitro histomorphometric comparison of dental pulp tissue in different teeth (v0.1)"

“…Dental pulp (DP) is an innervated, highly vascularized soft tissue that provides vitality to the tooth (Rodas-Junco et al 2017). DP is located inside each primary or permanent tooth, and its main functions include the generation of dentine and maintenance of its biological and physiological vitality in response to traumatic injuries, physical stimulus or bacterial infections (Marrelli et al 2018;Ravindra et al 2015;Tatullo et al 2015). The regenerative function of DP suggests that it contains odontogenic progenitor cells or stem cells that are involved in the regeneration process.…”
