Protocolo odontológico en paciente con labio y paladar hendido: Caso Clínico
Cleft lip and palate (CLP) is the most frequent congenital craniofacial malformation with an incidence in the general population of approximately 1:500; in Mexico is 1:700 live births, these patients have a higher incidence of congenital malformations, which will require more than one reconstructive surgery as treatment, in addition to a multidisciplinary treatment. This article presents the case of a 2 years 11 months old male patient with CLP, in which he underwent a comprehensive operative treatment that included pulpotomies, restorations with steel crowns, fluoride topication, sealants, and the placement of an obturator plate with transversal screw, which is maintained with periodic revisions. The results of the treatment were favorable, since the patient's upper jaw had already been expanded, in addition to receiving multidisciplinary care, which improved the patient's quality of life.

Level of knowledge and attitude of Pediatricians about early childhood caries and oral health in children in the City of Quito, 2021-2022
The prevalence of early childhood caries has been increasing rapidly globally, however, the highest prevalence is seen in developing countries, significantly influencing individuals, families and societies in a way that is related to with general health, quality of life and is related to other common diseases. childhood diseases, mainly due to risk factors in common with other non-communicable diseases, for example, a high consumption of sugar, and diseases related to other health disorders such as obesity. (World Health Organization, 2021). The level of knowledge and the attitude of paediatricians towards this problem is essential for correct prevention as the first providers of information on the health of infants. Therefore, this study aims to assess the level of knowledge and attitude of pediatricians about early childhood caries and oral health of children in the city of Quito. To the extent that there is no list of each of the pediatricians in the city of Quito, they were selected through a non-probabilistic sampling for convenience. The results suggest that about 58.5% of pediatricians recognized the importance of pediatric dentistry. About 72.7% of pediatricians perform oral exams regularly. About 17% of pediatricians are aware of CHD. Only 32.3% of pediatricians recognized the cariogenicity of medicated syrups.

Estudio comparativo in vitro sobre el grado de rugosidad superficial usando tres diferentes sistemas de pulido intraoral en cerámicas de silicato de litio reforzado con óxido de zirconio
The aim of this study was to evaluate the surface roughness of zirconia-reinforced lithium silicate ceramics treated with three different intraoral polishing systems from the manufacturers Garrison, Ultradent and Jota. The specimens were Celtra Duo ceramics (Dentsply Sirona) modeled by CAD/CAM in a CEREC unit, and then glazed. The glazed specimens were worn out with a diamond bur to simulate an occlusal adjustment in dental restorations and then treated with the different intraoral polishing systems. Polishing procedures were performed at two intervals of 40s each. Data was statistically analyzed using Student T-tests. All three systems managed to significantly reduce the roughness of the milled surface at the end of the first polishing interval, with significant differences between the three systems. In addition, it was observed that, at the end of the second interval, two systems achieved similar surface roughness, but smoother than the third system. None of the systems managed to recover the original roughness of the glazed ceramic surface. Finally, significant differences from one interval to the next suggest that surface roughness can be further reduced by extending polishing time; however, the increase in polishing time can influence the service life of intraoral instruments and working time. Consequently, the time needed to achieve optimal smoothness in each system should be considered as a key performance aspect in future research on intraoral polishing systems.

Tratamientos mínimamente invasivos para casos de fluorosis dental en Odontopediatría. Una revisión sistemática
Objective. The objective of this research was to determine the most effective minimally invasive treatment for cases of fluorosis in children and adolescents, taking into account the degree of severity through bibliographic review. Materials and Methods. Literature research was performed from January 2017 to October 2021 on minimally invasive treatments for cases of dental fluorosis in children and adolescents in five scientifically recognized databases in the field of health (Pubmed Central, Medline, Scopus, Science Direct and Cochrane Library). Following the PRISMA Methodology, of 900 articles resulting from the initial search, through the analysis of inclusion/exclusion criteria and quality of scientific evidence; 5 scientific articles are included for qualitative evaluation. Results. For the purposes of this review, the five studies selected with a high quality of evidence were clinical trials. The total number of participating girls/boys and adolescents was 287 with an age range of 6 to 17 years. These cases of dental fluorosis were treated with microabrasion, bleaching, application of infiltrating resin (ICON, DMG) and combined therapies. Said techniques present an efficacy that is inversely proportional to the degree of severity of dental fluorosis, being highly effective in masking minor lesions. Conclusion. The resin infiltration technique with double infiltration for 3 minutes and combined with whitening exhibits better aesthetic results and fewer limitations/adverse effects for cases of mild and moderate dental fluorosis (in stages 1 to 4 within the Thylstrup and Fejerskov index) in pediatric and adolescent patients.

REHABILITACIÓN INTEGRAL EN UNA SOLA CITA DE UN PACIENTE PRESCOLAR CON CARIES DE INFANCIA TEMPRANA
Abstract Early childhood caries (ECC) affects the 12% to 98% of the population and is associated with a negative impact on the infant"™s quality of life, even more so when it is not treated. ECC treatment aims to prevent further destruction of teeth, promote general health, and stop the disease process permanently. The objective of this article is to report a case of a comprehensive rehabilitation, in a single appointment, in a female preschool patient with ECC, from Santo Domingo de los Tsáchilas province in Ecuador. The rehabilitation consisted of surgical, endodontic, functional and aesthetic restorative treatments, with the need for future placement of space maintainers. The management of the pediatric patient during comprehensive oral rehabilitation in a single appointment can be a challenge for the pediatric dentist. Therefore, oral education will be essential for the oral health promotion and the prevention of ECC, mainly in areas with difficult access to quality dental treatment. Keywords: Early child hood caries, oral rehabilitation, oral education, oral health promotion.

The success of endodontic treatment will depend on the cleanliness and conformation of the root canal system. In clinical practice, the use of irrigants provides chemical disinfection of root canals and removal of the smear trapped inside the canal thanks to the efficient action of chelating solutions. The purpose of this study was to calculate the efficacy of removing the smear layer in the apical third, with the use of 17% EDTA and 10% citric acid activated with different devices and techniques such as passive ultrasonic irrigation (PUI) and EDDY tips (ED). Forty-five premolar teeth were randomly divided into five groups: 4 experimental groups (n=10) and 1 control group (n=5). In each root, two longitudinal grooves were prepared in the buccal and lingual, which were covered with gold for observation under the scanning electron microscope to thus quantify the open dentinal tubules. For the statistical analysis, the Shapiro-Wilk, Kruskal-Wallis test and a multiple comparison with U Mann-Whitney were used, which showed that the activation with EDDY has had the lowest scores of the experiment with a difference of 8 points with respect to PUI with EDTA at 17% and a difference with PUI of 13 points with citric acid at 10% in the apical third. However, none of the experimental groups was able to remove the entire dentin smear layer in the apical third, but they did present significant differences with respect to the control group, so the use of chelating solutions and an activation system is recommended to better obtain cleaning index and ensure a successful root canal treatment.

Cat Scratch disease: literature review and case report
Cat scratch disease is an uncommon infection caused by Bartonella Henselae bacteria. It has a reported incidence of 9.3 cases per 100 000 individuals and occurs in 80% of children aged between 2 and 14 years with a higher prevalence in men. The typical presentation of the disease is presented as cutaneous nodules at the site of inoculation with regional lymphoadenitis as well as nonspecific symptoms such as fever, malaise, headache among others. It is produced through a scratch or only by contact with an infected animal and the infecting microorganism is transported by macrophages from the site of inoculation to the lymph nodes. The gold standard in the diagnosis of this condition is an extensive clinical history and serological tests revealing high levels of IgM and IgG antibodies, so the objective of this study is to present a rare case of cat scratch disease in a female patient 9 years old who presented bilateral preauricular lymphadenopathy. In addition, a systematic review of the available literature was carried out in order to determine and describe the signs, symptoms, diagnosis, available treatment and prognosis of this disease.

Complications and satisfaction of rehabilitated patients with Zygomatic implants in a private clinic in Quito - Ecuador
The treatment of atrophic jaws using zygomatic implants was initially introduced by Branemark in 1988, since then several modifications have been presented in terms of its indications, pre-surgical planning and surgical technique. Currently being a safe and predictable long-term alternative. The objective of the present study was to analyze the presence of biological and biomechanical problems, as well as the satisfaction of patients rehabilitated with extrasinusal zygomatic implants with immediate loading, for which we retrospectively reviewed 21 zygomatic implants installed in 6 patients with atrophic maxillae or with a maxillectomy sequela who were treated in a private clinic in the city of Quito - Ecuador. The results of this study showed that only 9.52% of the implants presented biological complications, of which 1 implant presented oro-sinus communication (4.76%) and 2 implants presented maxillary sinusitis- (9.52% - the implant affected with the oro-sinus communication was repeated); In addition, all patients provided satisfactory responses in terms of general satisfaction with the treatment. It is concluded that the extrasinusal zygomatic implant technique is a reliable and reproducible technique that generates high rates patient satisfaction.

Deviation of permanent tooth germ after pulpectomy filled with zinc oxide eugenol.
Zinc oxide and eugenol (ZOE) is the first recommended and most studied material, until 2008 it was the only material recommended by the American Academy of Pediatric Dentistry as a root canal obturator. However, ZOE has shown relatively lower rates of resorption or degradation in correlation of primary teeth rhizolysis, causing irritation in the periapical area, bone and cement necrosis, and deviation of the permanent tooth germ. Therefore, the objective of this article is to verify that ZOE, after extravasation and its slower rate of degradation of primary teeth rhizolysis, can divert the permanent tooth germ. Faced with the diagnosis of persistence of the primary maxillary incisors due to extravasation and non-reabsorption of the obturator material (ZOE), the initial treatment in the reported clinical case was to perform the extraction of the dental units 5.2, 5.1, 6.1, 6.2 and the removal of extravasated obturator material remains to aid in the descent of the clinical crown of the permanent successor dental units. It should be noted that the obturator material (ZOE) caused, as evidenced by the literature, the deviation of the permanent germ (dental unit 2.1) which will subsequently be worked on in an interdisciplinary way.

The aim of this study was to compare marginal adaptation of Endosequence Root Repair Material (ERRM) and Bio-C Repair, as root-end filling materials. Twenty extracted, single-rooted teeth were standardized to 15 millimeters. The remaining roots were prepared and subsequently, they were filled using the continuous wave technique. Then, the apical 3 mm of the root was sectioned and root-end preparation was done with ultrasonic tips. Samples were randomly allocated in two groups: Group A, in which root-end cavities were filled with ERRM paste; and Group B, in which Bio-C Repair was used for root-end filling. Scanning electron microscope images at different magnifications were used in order to measure the gaps between both retrofilling materials and dentin walls. Results showed that ERRM paste showed a mean gap of 6.43 μm, while for Bio-C Repair, the mean gap was 7.5 μm. Statistical analysis revealed that there were no significant differences between the two groups. In conclusion, Endosequence Root Repair Material paste and Bio-C Repair have similar marginal adaptation when used as root-end fillings.

Comparar la efectividad de la irrigación ultrasónica dual del Anillo HBW (HBW, México) y la irrigación ultrasónica pasiva de IrriS (VDW Dental, Munich Germany) en la remoción de barrillo dentinario colocados artificialmente en irregularidades simuladas dentro de conductos radiculares instrumentados. El estudio se realizó en 25 premolares uniradiculares extraídos. Se instrumentaron los conductos con técnica reciprocante Reciproc Blue (VDW Dental, Munich Germany). Cada diente se dividió longitudinalmente en dos mitades. En una de las mitades de cada conducto se creó un surco de 4 mm de largo, 0,2 mm de ancho y 0,5 mm de profundidad, se rellenó el surco con barrillo dentinario preparado intencionalmente mezclando restos de dentina con NaOCl al 5,25%. Se volvió a ensamblar cada diente y se los distribuyó en 3 grupos de manera aleatoria: Grupo 1: irrigación ultrasónica pasiva PUI (n = 10), grupo 2 irrigación ultrasónica dual DUI (n = 10) en los cuales se irrigó 9 ml de NaOCl al 5,25% y se activó por 60s distribuidos en tres tiempos de 3ml/20s cada uno y grupo control (n = 5) en el cual no se realizó irrigación. Se separaron las raíces y se obtuvieron imágenes del surco, utilizando una cámara Nikon d3300 (Nikon,Tokio, Japan) luego de lo cual se guardaron como imágenes JPG. La cantidad de restos de barrillo dentinario en los surcos fue evaluada por tres expertos utilizando un sistema de puntuación de 0 a 3: cuanto mayor fue la puntuación, más barrillo dentinario fue observado en el surco. Los datos se analizaron mediante la prueba de Shapiro-Wilks y U de Mann-Whitney. La efectividad en la remoción de barrillo dentinario de cada sistema se comparó en 3 categorías de acuerdo a los puntajes obtenidos: puntaje de 0 a 1 Excelente; puntaje 2 Regular y puntaje 3 Mala. Una excelente remoción del barrillo dentinario se observó en el 60% y 70% en los sistemas DUI y PUI respectivamente, mientras que una remoción regular del 40% y 30% respectivamente. sin embargo, no hubo diferencias estadísticamente significativas mediante la prueba U de Mann-Whitney (P>0.05). La irrigación ultrasónica dual fue igual de efectiva que la irrigación ultrasónica pasiva en la remoción de barrillo dentinario.

Complete oral rehabilitation and behavior management in 3-year-old patient with severe early childhood caries. Case report.
Non-pharmacological behavior management techniques are the set of procedures aimed to improve a child's coping skills and, are useful for complete oral rehabilitations as they decrease fear and anxiety levels while facilitating the proper realization of treatment. Before starting dental procedures, the child must be evaluated to recognize his cooperation and psychological maturity degree, in this way we will be able to choose the techniques that best suit the patient. The efficacy, safety, and preference of parents for the use of these techniques versus sedation or general anesthesia has been reported. The objective of this clinical case is to demonstrate that, through a correct selection of basic behavioral management techniques, the collaboration and acceptance of treatment by a 3-year-old patient with previous negative dental experiences and severe early childhood caries was achieved.

Alteraciones bucales en adultos diabéticos que acudieron a dos Facultades de Odontologia del Paraguay
Diabetes in the geriatric population is a very frequent chronic condition, which can interact or cause various geriatric syndromes;the elderly adult diabetic is a problem of great sanitary importance, justified by its high prevalence, the difficulties for diagnosis, treatment and education, make it require a comprehensive evaluation of their physical condition and functional capacity, as acute and chronic complications they are more frequent and serious; the general dentist must be able to provide ambulatory care to healthy, at-risk, sick and sequelae people; as is diabetes in elderly adults that presents particularities in dental care. Therefore, this study was proposed whose objective was to identify the most frequent oral alterations in elderly adults and diabetic, the design was observational descriptive, cross-sectional and retrospective in which 105 patients from 58 to 65 years old participated, it has been observed that majority of the patients presented with cavities and periodontal disease, among the most frequent signs and symptoms, sensitivity and dental mobility were observed. The highest percentage of caries and periodontitis was observed in men
Molar Incisor Hypomineralization (MIH) prevalence in children between 9-12 years old in children between 9-12 years of age belonging to two schools in Quito, Ecuador; between February and March 2018
The Molar Incisor Hypomineralization (MIH) is a qualitative defect of the enamel that affects one or more definitive first molars, with or without commitment of the permanent incisors. The global prevalence of MIH ranges from 2.4% to 40% and, in South America, its average is 12.3%. The aim of this study is to estimate the prevalence of Molar Incisor Hypomineralization in schoolchildren between 9 and 12 years old through visual exploration. It was a cross-sectional, descriptive and qualitative study. 300 children from 9 to 12 years of age, who attended two schools in Quito, Ecuador, between February and March 2018, participated. They were examined by a calibrated operator. The diagnosis was established according to the criteria of the European Academy of Pediatric Dentistry and its severity according to Mathu - Muju and Wright criteria. The prevalence found was 13.7%. There is no association between the presence of HIM and the gender of the children. The majority of cases occurred in 10-year-old schoolchildren. The dental units most affected qualitatively and quantitatively were the first upper permanent molars. The dental units less affected qualitatively and quantitatively were the lower permanent lateral incisors.
Caliber-Persistent Labial Artery about a case
The labial artery of persistent caliber is a relatively rare lesion that can be found in different organs such as the stomach, jejunum or lips; which appears as an arterial branch of abnormally large diameter for its superficial situation. The persistence of the caliber of the labial artery usually occurs in the lower lip, but there are reports of its location in the upper lip, palate and buccal vestibule. It is an entity of controversial etiology, clinically manifested as a swelling or erosion that must be taken into account whenever an intraoral examination is performed to avoid invasive treatments that cause profuse bleeding. The objective of this publication is to report the case of a patient who presented persistent arterial caliber in the upper lip.
THE Early treatment of pseudo class III with Eschler Arc. Case Report
ABSTRACT Early treatment of malocclusion Class III returns harmony and functionality to the stomatognathic system by simplifying more complex corrective procedures. This type of treatment is important to provide the necessary conditions for growth and development of both the maxilla and jaw, making them become harmonious and thus avoiding unfavorable complications. This case exposes a 6-year-old female patient treated at the San Francisco de Quito University clinic. The patient presented class III malocclusion; her representative indicated that the patient possesses a class III hereditary pattern of her paternal family. The present case shows the use of Scheler's arch as a treatment option for this type of malocclusion in primary dentition after a precise diagnosis. Key words: Early treatment, malocclusion Class III, Scheler's Arch
Xerodermia Pigmentosa. Reporte de dos casos clínicos
Xeroderma pigmentosa (XP) is an autosomal recessive disorder. It presents with cutaneous manifestations such as the appearance of stains, freckles, erythema, vesicles, carcinomas and melanomas in exposed areas of solar radiation, including skin and mucous membranes. In addition to eye injuries such as photophobia, conjunctivitis, ulcers, blindness and in some cases neurological alterations. We present two clinical cases of patients with a diagnosis of xeroderma pigmentosa with cutaneous, ophthalmological and oral manifestations. The objective of this article is to present the oral manifestations that occur in xeroderma pigmentosa, its early diagnosis, treatment and prevention of them. Keywords: xeroderma pigmentosa, melanoma, cancer, oral manifestations.
Immediate Implant placement into fresh extraction mandibular molars sockets with or without bone grafting. Clinical cases report.
Objectives: The aim of this series of cases was to evaluate the differences and reactions of tissues around immediate implants placed in infected or noninfected sockets in mandibular molars, with or without bone graft placement. Methods: Four immediate implants were placed in infected or non-infected mandibular molar sockets in four patients. The patients were divided into 2 groups (n=2). In Group 1 a bone graft was placed and in Group 2 no bone graft was placed. Clinical and radiographic evaluations were performed 8 days and 4 months after implant placement in all patients. Results: At 4 months follow-up, both groups showed favorable bone-implant integration, and the survival rate of both groups was 100%. No greater difference was observed between the 2 groups to the radiographic evaluation at 8 days and 4 months related to changes in the level of the bone crest in the vertical and horizontal direction. No major differences were found in bone and soft tissue regeneration between cases where bone graft was placed, and in the cases where bone grafting was not used. Conclusions: Within the limitations of this study, we can conclude that immediate implant placement in infected or noninfected sockets in mandibular molars, with bone graft or without grafting does not present differences.
