La Ley 1581 de 2012 constituye el marco general de la protección de los datos personales en Colombia, entiéndase por datos personales toda aquella información asociada a una persona y que permite su identificación. El objetivo de la ley es garantizar la intimidad, derecho a la privacidad y el buen nombre de las personas en el proceso del tratamiento de los datos personales bajos los principios de confidencialidad, seguridad, legalidad, acceso, libertad y transparencia.
Existe un ente que actúa como un tribunal de ética profesional que ejerce inspección control y vigilancia de la ingeniería, sus profesiones afines y auxiliares llamado COPNIA el cual tiene como objetivo que los profesionales ejerzan adecuadamente la profesión y enaltezcan la misma.
En el mundo de la ciberseguridad existen procesos que se ejecutan para medir la seguridad de los sistemas como son las pruebas de penetración o pentesting las cuales verifican diferente tipos de ataques cibernéticos con el fin de encontrar fallas, errores o vulnerabilidades en un sistema de seguridad, su efectividad radica en que se utilizan las mismas herramientas y procesos que los delincuentes emplean para tener acceso a la información, la diferencia es que se hace en un entorno controlado y autorizado.
Palabras claves: Blue Team, Red Team, datos personales, privacidad, COPNIA, ciberseguridad, pentesting, ataques, vulnerabiliades.This technical report whose objective is to relate all the relevant aspects of the development of the activities carried out in the previous stages, seeks to capture the actions of the Blue Team and Red Team as well as to know legal aspects in Colombia such as Law 1273 of 2009 that protects the Well protected legal information and data, regulates the protection of information, personal data and fully preserves the systems that use information and communication technologies.
Law 1581 of 2012 constitutes the general framework for the protection of personal data in Colombia, meaning personal data is all information associated with a person and that allows their identification. The objective of the law is to guarantee privacy, the right to privacy and the good name of people in the process of processing personal data under the principles of confidentiality, security, legality, access, freedom and transparency.
There is an entity that acts as a professional ethics court that exercises inspection, control and surveillance of engineering, its related and auxiliary professions called COPNIA, which aims for professionals to adequately exercise the profession and enhance it.
In the world of cybersecurity there are processes that are executed to measure the security of systems, such as penetration tests or pentesting, which verify different types of cyber attacks in order to find flaws, errors or vulnerabilities in a security system. Its effectiveness lies in the use of the same tools and processes that criminals use to access information, the difference is that it is done in a controlled and authorized environment.

"Wire Syndrome" Following Bonded Orthodontic Retainers: A Systematic Review of the Literature.
(1) Background and objective: Tooth movements described as unexplained, aberrant, unexpected, unwanted, or undesirable can occur in the presence of an intact orthodontic retention wire, without detachment or fracture. This iatrogenic phenomenon, known little or not by many practitioners, responsible for significant dental and periodontal complications, both functional and aesthetic, is called "Wire Syndrome" (WS). It is therefore considered an undesirable event of bonded orthodontic retainers, which must be differentiated from an orthodontic relapse. The objective was to perform, for the first time, a systematic review of the literature in order to define the prevalence of WS and to study its associated clinical characteristics. (2) Methods: A systematic review of the literature was performed following the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and recommendations using an electronic search strategy on four databases complemented by a manual search. All the prospective and retrospective clinical studies, including case reports and series, written in English or French, clearly mentioning the description, detection, or management of WS were included. Three independent blinding review authors were involved in study selection, data extraction, and bias assessment using the Mixed Methods Appraisal Tool (MMAT). (3) Results: Of 1891 results, 20 articles published between 2007 and 2021 fulfilled the inclusion criteria, with a globally high risk of bias since 16 articles were case report/series. The analysis of each article allowed the highlighting of WS through 13 categories, as follows: prevalence, apparition delay, patient characteristics, arch and tooth involved, families of movements, dental and periodontal consequences, type of wire, risk factors, etiologies, treatment, and preventive approach. (4) Conclusion: This systematic review of the literature elaborated a synthesis on WS, allowing general practitioners, periodontists, and orthodontists to understand this adverse event, to facilitate the diagnostic approach, and to underline preventive measures against WS. This review was registered in the International Prospective Register of Systematic Reviews (PROSPERO; number CRD42021269297)
The effect of connective tissue graft or a collagen matrix on epithelial differentiation around teeth and implants: a preclinical study in minipigs.
OBJECTIVES
This study aimed to histologically evaluate the healing at 8 weeks after coronally advanced flap (CAF) with either a superficial (SCTG) or deep palatal connective tissue graft (DCTG), or a collagen matrix (CM) to cover recession defects at teeth and implants.
MATERIAL AND METHODS
One mandibular side of 6 miniature pigs received each 3 titanium implants 12 weeks after extraction. Eight weeks later, recession defects were created around implants and contralateral premolars and 4 weeks later randomly subjected to CAF + SCTG, CAF + DCTG, or CAF + CM. After 8 weeks, block biopsies were histologically analyzed.
RESULTS
For the primary outcome, i.e., keratinization of the epithelium, all teeth and implants exhibited a keratinized epithelium with no histological differences among them also not in terms of statistically significant differences in length (SCTG 0.86 ± 0.92 mm, DCTG 1.13 ± 0.62 mm, and Cm, 1.44 ± 0.76 mm). Pocket formation was histologically seen at all teeth, around most implants with SCTG and DCTG, however not in the CM implant group. The connective tissue grafts showed hardly signs of degradation, whereas the CM was partly degraded and integrated in connective tissue. The mean gain in gingival height was similar in all experimental groups (SCTG 3.89 ± 0.80 mm, DCTG 4.01 ± 1.40 mm, CM 4.21 ± 0.64 mm). Statistically significant differences were found in the height of the junctional epithelium between the control teeth and the connective tissue groups (p = 0.009 and 0.044).
CONCLUSIONS
In this animal model, the use of either a superficial or deep connective tissue graft or a collagen membrane did not seem to have any impact on the epithelial keratinization around both teeth and implants. All procedures (CAF + SCTG/DCTG/CM) resulted in a long JE that was even longer at implants.
CLINICAL RELEVANCE
Deep/superficial palatal connective tissue graft yielded similar keratinization around teeth/implants. Given the absence of pocket formation and inflammatory processes at implants when using a CM, CAF + CM might bear potential clinical benefits

Cost of diabetic retinopathy and macular oedema in a population, an eight year follow up
Decision making in root-coverage procedures for the esthetic outcome
The primary indication for treatment of gingival recessions is esthetics. In the last decades, patients have become increasingly more demanding in the esthetic outcome expected. In order to obtain a successful final result, periodontal plastic surgery should provide not only complete root coverage but also perfect blending in terms of color and texture. In the literature, many techniques have been demonstrated to be effective in obtaining complete root coverage, and the selection of one surgical technique over another depends on several factors related to the anatomic characteristics of the defect. The purpose of this paper was to suggest a decision-making process which starts from the clinical observation of the defects and is structured in progressive nodes that will guide the clinician through the most suitable surgical technique to achieve the ideal esthetic outcome

OBJECTIVE:
To clinically evaluate the treatment of Miller Class I and II multiple adjacent gingival recessions using the modified coronally advanced tunnel technique combined with a newly developed bioresorbable collagen matrix of porcine origin.
METHOD AND MATERIALS:
Eight healthy patients exhibiting at least three multiple Miller Class I and II multiple adjacent gingival recessions (a total of 42 recessions) were consecutively treated by means of the modified coronally advanced tunnel technique and collagen matrix. The following clinical parameters were assessed at baseline and 12 months postoperatively: full mouth plaque score (FMPS), full mouth bleeding score (FMBS), probing depth (PD), recession depth (RD), recession width (RW), keratinized tissue thickness (KTT), and keratinized tissue width (KTW). The primary outcome variable was complete root coverage.
RESULTS:
Neither allergic reactions nor soft tissue irritations or matrix exfoliations occurred. Postoperative pain and discomfort were reported to be low, and patient acceptance was generally high. At 12 months, complete root coverage was obtained in 2 out of the 8 patients and 30 of the 42 recessions (71%).
CONCLUSION:
Within their limits, the present results indicate that treatment of Miller Class I and II multiple adjacent gingival recessions by means of the modified coronally advanced tunnel technique and collagen matrix may result in statistically and clinically significant complete root coverage. Further studies are warranted to evaluate the performance of collagen matrix compared with connective tissue grafts and other soft tissue graft
Predictability of surgical techniques used for coverage of multiple adjacent gingival recessions--A systematic review
Predictable coverage of multiple adjacent gingival recessions (MAGRs) is a major challenge for clinicians. Although several surgical techniques have been proposed to treat MAGR, it is still unclear as to what extent the proposed approaches may lead to predictable root coverage. The aim of this article is to identify the predictability of the available surgical techniques used to achieve complete root coverage (CRC) of Miller Class I, II, and III MAGRs
Soft and hard tissue changes after immediate implant placement with or without a sub-epithelial connective tissue graft: Results from a 6-month pilot randomized controlled clinical trial
Aim: The present pilot RCT aimed to investigate the influence of a connective tissue graft (CTG) in combination with the immediate implant placement (IIP) on hard and soft tissue healing, without a bone replacement graft in the gap between the implant and the socket walls.
Materials and methods: Thirty patients requiring extraction of one anterior tooth (from premolar to premolar) were randomly assigned to one of the two treatment groups (test: IIP + CTG; control: IIP). Cone-beam computed tomography and optically scans were performed before tooth extraction and at 6-month follow-up. Then, DICOM files were superimposed in order to allow the evaluation of osseous ridge and buccal bone changes, while the superimposition of DICOM and Standard Tessellation Language files allowed for evaluating of soft tissue contour. For testing the differences between the two groups, the non-parametric test as Wilcoxon rank-sum test, was used.
Results: Twenty-six of the 30 enrolled patients attended the 6-month follow-up visit. The four patients of the control group that were lost to follow-up were analysed under the intention-to-treat principle. No statistically significant differences between the groups were observed for the vertical buccal bone resorption (p = .90), as well as for the horizontal buccal bone resorption at all measured levels. Significant differences were found between the test and control groups in the horizontal dimensional changes of osseous ridge at the most coronal aspect (p = .0003 and p = .02). Changes in tissue contour were between -0.32 and -0.04 mm in the test group and between -1.94 and -1.08 mm in the control group, while changes in soft tissue thickness varied between 1.33 and 2.42 mm in the test group and between -0.16 and 0.88 mm in the control group, with statistically significant differences for both variables at all measured levels. At 6 months, the mean volume increase was 6.76 ± 8.94 mm3 and 0.16 ± 0.42 mm3 in the test and control groups, respectively, with a statistically significant difference.
Conclusions: The findings of the present study indicate that the adjunct of a CTG at the time of IIP, without bone grafting, does not influence vertical bone resorption. Within the limits of this study, it can be suggested that the adjunct of a CTG at the time of IIP, without bone grafting, reduces the horizontal changes of the alveolar ridge. Moreover, it allows maintenance of the tissue contour due to an increase in soft tissue thickness
