Is Palatal Rugae Pattern a Reliable Tool for Personal Identification following Orthodontic Treatment? A Systematic Review and Meta-Analysis

Abstract

Background: To qualitatively and quantitatively review the reliability of palatal rugae as a tool for personal identification following orthodontic treatment. Methods: Cross-sectional retrospective studies assessing the accuracy of matching palatal rugae pattern pre- and post-orthodontic treatment were identified from PubMed and SCOPUS databases. The title and abstract of the articles identified in the search were screened for potential duplicates and relevancy to the topic of interest. The full text of the articles selected in the screening was analyzed using the inclusion and exclusion criteria. Quantitative analysis of the studies representing coherent data in terms of age and treatment choice was performed using RevMan software. Results: Out of 64 screened articles, only 18 articles fulfilled the eligibility criteria and were included in the systematic review. Out of these 18 articles, only 3 studies had data compatible with the quantitative analysis. Significant changes were noted in lateral first rugae in transverse bilateral direction (p = 0.02) and between second and third lateral rugae of the left side in the anteroposterior direction (p = 0.04). Despite the dimensional changes, observers in most studies were able to accurately (>90%) match the palatal rugae pre- and post-orthodontic treatment through visual observation. Conclusion: The accuracy of the visual matching, despite the significant dimensional changes, indicates that morphology could have potentially been the major matching factor. Thus, a combination of dimensional and morphological evaluation of the palatal rugae could potentially increase the accuracy of personal identification.

Reliable Person Identification Using a Novel Multibiometric Image Sensor Fusion Architecture

“…In the initial phase, data sensed from the surroundings is classi ed according to how it satis es the application's demands. The research [13] evaluated the validity of palatal rugae as a device for identity after orthodontic treatment, both qualitatively and numerically. The study [14] investigated that uses CNN's dense learning framework to suggest a highly accurate and robust ECG-based person identi cation system.…”

Alterações morfológicas do padrão de rugosidade palatal após crescimento esquelético facial

“…Neste estudo, analisando as alterações sofridas pelas rugas palatinas antes e após o pico de crescimento esquelético facial, a morfologia das rugas primárias e secundárias apresentou alterações morfológicas leves no período anterior quando comparada ao período posterior. Esse achado ratificou que as rugas não sofrem significativas alterações morfológicas mesmo após tratamento cirúrgico e/ou ortodôntico em região de palato 5,20 . A forma da papila incisiva, a direção do alinhamento das rugas e a morfologia da rafe palatina mediana permaneceram dimensionalmente estáveis na comparação.…”

“…As rugas palatinas sofrem alterações dimensionais ântero-posteriores e transversais ao se comparar os períodos pré e pós-pico de crescimento ósseo, nas quais são esperadas expansões da maxila. De acordo com a morfologia das rugas, não houve diferenças significativas na comparação pré e pós-tratamento, porém cerca de 10% das morfologias foram modificadas após o tratamento, resultado semelhante ao estudo de Gupta et al 20 .…”

A morphometric approach to morphology analysis of palatal rugae in sibling groups

“…The stable nature of palatal rugae has led to extensive research in the field, with the aim of finding an alternative identification tool [7,8]. The orientation and forms of palatal rugae are governed by the fibroblasts and core collagen fibers that run anteroposteriorly.…”
