It recognizes the contribution that these systems have made to improve the quality of publications and articles but emphasizes the need to involve academic communities to determine the value of knowledge and the processes to generate it. It also reflects on the context of dental research, the strategies that Universitas Odontologica has used to fulfill its mission and vision, and its challenges as a small institutional journal in dentistry.</p> 2018-10-05T00:00:00-05:00 Copyright (c) 2018 Dental School, Pontificia Universidad Javeriana http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23690 Frequency and Characteristics of Incidental Findings in Panoramic Radiographs and Bone Variations in People with Total Edentulism 2018-10-10T17:01:45-05:00 Johan Escolano Rivas johanescolano@gmail.com Silvia Barrientos Sánchez barrien@javeriana.edu.co Adriana Rodríguez Ciodaro arodrig@javeriana.edu.co <p><strong><em>Background:</em></strong> According to the 2014 National Oral Health Study, 5.20 % of the Colombian population has total edentulism and 32.8 % in the population over 65 years of age. However, other parameters relevant to the correct approach to edentulism should be analyzed with radiographic studies. <strong><em>Purpose:</em></strong> To identify the frequency and characteristics of the findings and bone variations in panoramic radiographs of totally edentulous patients. <strong><em>Methods:</em></strong> A descriptive, observational study was carried out on 10.000 panoramic radiographs, from which those corresponding to patients with total edentulism were analyzed using the CliniView 9.3 program. Variables of sex, age, alveolar ridge height, mandibular branch height and condyle, as well as radiographic findings were recorded. <strong><em>Results:</em></strong> 112 radiographs of patients with total edentulism were found, 51.8 % with some type of incidental finding. Most frequent were implants 33.9 % followed by root remains in 13.4 %. There were no differences in the averages of the bone measurements on both sides. Men have higher alveolar ridge height in the lower jaw than women (p &lt;0.05). Condylar height values ​​were similar for both sexes. A higher value of the height of the mandibular branch was found in men (p &lt;0.05). <strong><em>Conclusions:</em></strong> Frequency of radiographic incidental findings in total edentulous patients is considerable. The bony variations caused by the absence of teeth must be taken into account when making clinical decisions of restoration with total prosthesis or with implants.</p> 2018-10-10T00:00:00-05:00 Copyright (c) 2018 Johan Escolano Rivas, Silvia Barrientos Sánchez, Adriana Rodríguez Ciodaro http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23705 CAD-CAM in Complete Dentures.

Such retractions cause periodontal problems to patients due to the cleaning access limitations. Edlan Mejchar vestibuloplasty technique allows controlling, in one intervention and a single surgical field, etiological factors and a creeping gingival attachment by eliminating tensional forces. <strong><em>Purpose</em>: </strong>To describe the effectiveness of Edlan Mejchar technique to solve gum retractions caused by tensional forces in four clinical cases. <strong><em>Description of cases:</em> </strong>Four patients with gingival retractions in lower incisors and little adhered gingiva due to lower lip frenulum tension seek dental treatment. Edlan Mejchar vestibuloplasty was the surgical treatment chosen, which consisted of&nbsp; supraperiosteal incisions and internal dissections in connective tissue. <strong><em>Results</em>: </strong>The percentage of root coverage achieved was close to 60 % and abnormal frenulum insertions were eliminated. <strong><em>Conclusion</em>:</strong> Vestibuloplasty through Edlan Mejchar technique showed favorable results in the cases described in which the labial frenum exerted tensional forces on the periodontium of lower anterior teeth.</p> 2018-10-05T00:00:00-05:00 Copyright (c) 2018 Dental School, Pontificia Universidad Javeriana http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23689 Type A Botulinum Toxin as Complement to Gingivoplasty in the Treatment of Gummy Smile. Case Report 2018-10-10T17:02:02-05:00 Irineu Gregnanin Pedron igpedron@alumni.usp.br <p><strong><em>Background</em></strong>: The pursuit of esthetic excellence has become a major goal in the dental treatment. Gummy smile is one of the complaints of the patients, since such a situation can influence self-esteem and social relationships. The beauty of the smile is not only constituted by the shape, position and size of the teeth, but also based on the characteristics of the gingival tissue and conformation of the lips, which should be as harmonious as teeth. The development of new more conservative techniques may provide a better therapeutic option than surgical procedures, such as the application of botulinum toxin, in the treatment of gummy smile. <strong><em>Purpose</em></strong>: to present the case of a patient who presented dentogingival discrepancy caused by gingival overgrowth and gummy smile, treated by gingivoplasty and complemented by application of botulinum toxin. <strong><em>Description of the case</em></strong>: The gingivoplasty was performed followed by the application of botulinum toxin type A. <strong><em>Results</em></strong>: The gingivoplasty resulted of the improvement of gingival arches and the application of botulinum toxin promoted the dehiscence of upper lip, reducing the gingival exposure. <strong><em>Conclusions</em></strong>: The application of botulinum toxin, associated with gingivoplasty, is an important tool at the management of gummy smile, optimizing smile harmony and achieving improved self-esteem and quality of life.</p> 2018-10-09T23:32:51-05:00 Copyright (c) 2018 Irineu Gregnanin Pedron http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23638 Exostosis 7 Years after Alveolar Ridge Augmentation with Pocket Technique 2018-10-10T17:02:12-05:00 Pablo Emilio Molano Valencia pablomol42@hotmail.com Bibiana Inés Yepes Ramírez bibyepes@yahoo.com Claudia Londoño Espinosa dra.claudialondono@gmail.com <p><strong><em>Background:</em></strong> Soft-tissue treatment techniques for alveolar ridge augmentation include connective tissue grafts, with or without epithelial collar, and roll techniques. Sometimes, there are postoperative complications. <strong><em>Purpose:</em></strong> To describe a case for a female patient who underwent an&nbsp; alveolar ridge augmentation and developed an exostosis. <strong><em>Case description:</em></strong> A 35-year-old female patient underwent an alveolar ridge augmentation procedure through a pocket technique in the upper right central incisor. A connective tissue graft without epithelial collar from the palate was transplanted and covered with the flap. Seven years later the patient returned with an exostosis in the buccal area of the treated tooth that affected her aesthetically. An osteoplasty was performed and a bone biopsy was taken, whose histopathological analysis showed a bone-compatible tissue. <strong><em>Conclusion:</em></strong> Exostosis is an unusual postoperative complication in cases of alveolar ridge augmentation that can be successfully treated. More research is necessary about such complications.</p> 2018-10-05T18:37:21-05:00 Copyright (c) 2018 Dental School, Pontificia Universidad Javeriana http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23702 New Orthopedic Fixed Appliance to Treat Class II, Division 1 Malocclusions. Case Report 2018-10-10T17:02:22-05:00 Rosmery Cecilia García Ramos orto.ros@hotmail.com <p><strong><em>Background</em></strong><strong>:</strong> Early correction of class II malocclusions associated to mandibular retrognathism is possible through sustained and continuous mandibular advancement that does not require patient collaboration.&nbsp; <strong><em>Purpose</em>:</strong> To describe a case of malocclusion treated with a new fixed mandibular advance arch (FMAA). <strong><em>Case description</em>:</strong> FMAA was applied to a 11-year-6-month-old skeletal class-II, division-1 girl with mandibular retrognathism and overbite. <strong><em>Results</em></strong>: After one-year treatment, there were functional and esthetic outcomes. ANB angle was reduced from 6.6° to 5.0°. Effective mandibular length (Co-Gn) increased (96.1 mm to 103.4 mm). Upper incisors inclinations went from 28,0° to 28,4°. Lower incisors experienced slight proinclinations (26.2° to 30.9°). Cephalograms after orthodontic treatment showed stable measures: ANB went from 5.0° to 5,1° and Co-Gn remained stable in 103.4°. Upper incisors had retroinclinations from 28.4° to 22.5° and lower incisors went from 30.9° to 28.2°. <strong><em>Conclusion</em>:</strong> FMAA is a treatment alternative for mixed and early permanent dentitions for being a fixed appliance, it allows advancing mandible without requiring patient collaboration and during the necessary time to obtain changes. Because of its simple structure (cemented in the maxilla only to first molars), it advances without being fixed to the mandible every time the patient closes the mouth. In addition, it is easy to make, cement, activate, clean, and keep in mouth.</p> 2018-10-10T13:54:04-05:00 Copyright (c) 2018 Rosmery Cecilia García Ramos http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23652 Frequency of Odontogenic Cysts and Tumors in Nicaraguan Population.

There are no epidemiological data of the frequency of these lesions among Nicaraguans. <strong><em>Purpose</em></strong>: To establish the relative frequency of OCTs in Nicaraguan population. <strong><em>Methods</em></strong>: This was a retrospective study in which excisional biopsy records of regional hospital pathology departments from the cities of León, Managua, Estelí, Matagalpa, and Jinotega, obtained between 2010 and 2016, were analyzed. The pathologies were classified using the World Health Organization 2017 guidelines. Data analysis was descriptive through relative frequencies. <strong><em>Results</em>:</strong> There were 109 OCT cases (0.8 %) out of 13,102 reports reviewed. Distribution by sex was 50.9 % men and 49.9 % women, mainly in the 11-to-30-year age range. The most frequent cyst was &nbsp;dentigerous cyst (69.5 %) and the most common odontogenic tumor was ameloblastoma (50 %), predominantly in the jaw. <strong><em>Conclusion</em>:</strong> This study provides epidemiological information on OCTs from five Nicaraguan cities. These data are important to identify groups at risk and possible associated factors, and to implement differential diagnostic and adequate treatment systems.</p> 2018-10-07T20:40:33-05:00 Copyright (c) 2018 Luis Alberto Quintana Salgado, Luis Javier Espinoza Hernández, José Javier Rodríguez Vílchez, Carlos David Guerrero Midence, Harley José Rugama Díaz http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23708 Author Index, Volume 36 2018-10-10T17:02:39-05:00 Universitas Odontologica universitas.odontologica@gmail.com 2018-10-10T00:00:00-05:00 Copyright (c) 2018 Universitas Odontologica http://revistas.javeriana.edu.co/index.php/revUnivOdontologica/article/view/23709 Keyword Index, Volume 36 2018-10-10T17:02:40-05:00 Universitas Odontologica universitas.odontologica@gmail.com 2018-10-10T00:00:00-05:00 Copyright (c) 2018 Universitas Odontologica
