Research progress on ossification by titanium nanotube implant modification / 口腔疾病防治

@#Surface modification of titanium implants is a hot topic for improving osteointegration and includes physical, chemical, bioactive and anodization methods. Among these methods, anodization methods can form TiO2 nanotube structures with a uniform and stable structure, and TiO2 nanotubes and substrates have high binding strengths and osteogenic properties and represent an excellent method for implant modification. TiO2 nanotube osteogenesis is closely related to its morphology, diameter and physicochemical characteristics. Therefore, the structure of TiO2 nanotubes with optimal osteogenic performance can be prepared by regulating these factors. At present, research on TiO2 nanotubes is mostly focused on composite treatments with TiO2 nanotubes, namely, the combination of other implant modification methods (physical method, chemical method, biological method) and TiO2 nanotubes to form a composite structure to work synergistically to treat osteogenesis. TiO2 nanotube composite treatment is a good prospective application for the further preparation of TiO2 nanotube-modified structures with strong osteogenic properties.

Palatal rugae for the construction of forensic identification / Rugas palatinas en identificación forense

This study aims to explore the role of palatal rugae pattern in forensic identification by coding of palatal rugae characteristics, and to construct a forensic identification system for oral palatal rugae. One hundred models were included in this study for a systemic coding of palatal rugae pattern based on the shape, quantity, location, and distribution of palatal rugae. Among the involved 100 models, palatal rugae types varied among individuals and palatal rugae pattern was different between men and women, even between two sides in the same individual. Palatal rugae pattern can be used for forensic identification of oral soft tissue and this study proposes a new means for the identification by coding of palatal rugae pattern based on the shape, quantity, location and distribution.

Este estudio tuvo como objetivo explorar el patrón de rugas palatinas en la identificación forense mediante la codificación de las características de éstas. Además se elaboró un sistema de identificación forense. Fueron incluidos cien modelos para una codificación sistemática del patrón de rugas palatinas basado en su forma, cantidad, ubicación y distribución. En todos los modelos se identificó una variación entre los individuos y en el patrón entre hombres y mujeres. El patrón de rugas palatinas puede ser utilizado para la identificación forense de tejido blando oral y este estudio propone un método nuevo para codificarlas.
