The nutritional status (NS) of a child is important since there are essential nutrients needed for the development of craniofacial structures that, when low, compromise the body. One way to monitor and prevent the effects of malnutrition is with the age-appropriate anthropometric assessment (height-for-age) and BMI-for-age. Objec- tive: Determine the association between delayed eruption (DE) of permanent teeth and NS in children aged 6 to 12 years from the districts of Canchaque and San Miguel de El Faique at the months of June and July 2018. Material and methods: 354 children aged 6 to 12 years old from the districts of Canchaque and San Miguel de El Faique are examined and the sociodemographic variables, NS and DE are recorded. Prevalences are analyzed and assessed for associations. Variables are reported in frequency tables and associated NS with DE through contingency tables and calculating their OR And RP. Results: The prevalence of individuals with at least a de- ficient anthropometric valuation (VAM) is 43%, and DE is = 26%. When assessing relationships, a statistically significant association (O.R.= 2.42 IC = 1.49-3.91) (RP=1.90 p<0.001) between the VAM-height-for-age and DE is described. Conclusions: The prevalence of DE cases was higher than in other studies. There is an association between the NS of the individuals and DE with a positive statistical correlation between them, especially a VAM height-for-age and DE.

Nasopalatine Canal (NPC) is an important structure that may be susceptible to damage during surgical procedures in the anterior maxilla, therefore a thorough examination of the anatomy and variants of the NPC is imperative for a good diagnosis and an appropriate treatment plan. Objective: To perform an anatomic characterization of NPC using Computed Beam Computed Tomography (CBCT). Material and methods: 154 images of CBCT were evaluated, in which the NPC was analyzed in terms of length, shape, and inclination with respect to the hard palate and the maximum anteroposterior of the incisive foramen (IF) in men and women of 18 years of age and onwards. Results: to the evaluation of the NCP in sagittal slices of CBCT, it presented different forms, it was found to the cylindrical shape as the most common in 89 patients (58%), followed by the funnel shape in 38 (25%), and the less frequent were the shape of hourglass in 20 (13%) and spindle (5%). The average length of the NCP was 10.83 mm (± 2.13), the average of the anteroposterior diameter of the FI was 3.44 mm (± 0.80) and the average angulation of the CNP in relation to the hard palate was 16.44 ° (± 7.32). Conclusions: The study showed the variability of NCP in the Peruvian population, like in shape, length and inclination, as well as the diameter of the FI.

Objectives: Compare the dimension of the upper and lower pharyngeal airspace between the skeletal deformities class I, II and III in cephalometric radiographs. Material and methods: A retrospective type of study was made where there were analyzed 106 side radiogra- phies, taken in the X-ray center of the University health Center of the Peruvian University of Applied Sciences UPC between the years 2011 and 2014. Through the program Nemoceph® the main cephalometrics points and tracings were marked to be able to obtain the skeletal deformity (Steiner) and the dimension of the upper and lower airspace (McNamara). Results: In the upper pharyngeal airspace it was found that the highest aver- age dimension was 17.68 mm founded in the dentofacial deformation class III, and the lowest in class II with a value of 13.71 mm. Fort the lower airspace, the highest average was 15.98mm and the lowest 13.19mm, also founded in skeletal deformation Class III and Class II respectively. While comparing the size of the pharyngeal space between classes of deformity, it was found that there is statistically significant difference between the upper airspace of skeletal deformities class II and III with a value of p = 0.001; and in the lower, between classes III - I and III - II with values of p=0.0236 and p=0.0042 respectively. Conclusions: In this study it was found that there is a statistically significant difference in the upper and lower pharingeal airspace between the three dentofacial skeletal deformities.

Objective: To evaluate the tomographic characteristics of the mineralization of the stylohyoid process by volu- metric computed tomography (CT). Material and Methods:  reviewed 860 volumetric computed tomographies (593 correspond to the female sex and 267 to the male sex) of the Oral and Maxillofacial Radiology Service. The age range was between 6 to 89 years. The tomographic adequacy of the Langlais classification was used. The statistical analysis was performed using the chi-square test. Results: 289 MPE were found, bilateral mineraliza- tion prevailed (68.86%). The arithmetic average length of the MPE was 39.54 mm. The frequency of MPE was 33.60% (289 cases). It was found more frequently in the age group of 40 to 49 years, there was no significant difference between the female and male sex (p = 0.5367). In the classification of Langlais the most frequent type was the segmented variants with 42.2%. The most frequent MPE pattern was the partially calcified variants with 58.8%. Conclusions: The frequency of the MPE was 33.60% and the TCV allows to identify this anatomical variation in a timely manner.

Older adults are more prone to suffer diseases and comorbidities that affect their oral condition, so they need prosthodontic treatments conditioned to their systemic state to restore their masticatory, aesthetic and oral harmony function. However, the poor culture of prevention and the lack of specialized professionals in their care greatly hinders this work. Objective: To determine the prosthodontic treatments in older adults performed in the Service of Estomatología in Pacientes Especiales of the Centro Dental Docente Cayetano Heredia from april 2016 to december 2018. Material and methods: An observational, descriptive, cross-sectional, and retrospective study was carried out in a sample of 144 older adults with 200 treatments performed. Demographic variables such as sex, age group and origin wereconsidered. A database was developed, and later tables of contents for the analysis of its results. Results: removable partial denture was the most performed treatment for both sexes, 39.8% (n = 57) for the female sex and 38.6% (n = 22) for the male sex. According to the age group, the old- old were the patients who performed the most removable partial denture with 40.19% (n = 43). Most of the patients from Lima Norte underwent removable partial denturetreatment with 41.96% (n = 47). Conclusions: The removable prostheses predominated more than the fixed ones, being the removable partial denture the one that was performed the most. It was also evidenced that the female sex received more prosthodontic treatments and that the place of origin that was most recorded was Lima Norte, possibly due to its proximity to the dental center.

At present, high-tech procedures focused on restorations based on dental ceramics have allowed the evolution and improvement of different forms of manufacturing restorations, thus initiating the use of ceramics such as zirconium dioxide. Objective: To identify recent publications of zirconium dioxide based restoration materials that include clinical studies, mechanical, physical and aesthetic properties, as well as their evolution, manufacturing and various applications in daily clinical practice. Materials and methods: The systematic search of the literature will be carried out in the databases of PubMed and Ebsco, publications from 2010-2019 will be considered and that they were clinical, laboratory research and all those that showed the evolution in time of zirconium dioxide , as well as its applicability and diversification. Results: 48 articles were reviewed that met the selection criteria for the literature review. It was found that all prosthetic restorations based on zirconium dioxide, regardless of their use, showed a clinical performance very similar to three years, after that time, will depend on the type of use, composition and choice of case. Conclusions: The clinical success of restorations based on zirconium dioxide is due to the multiple mechanical advantages and, with the recent structural modifications, added to the addition of additives for stabilization, is emerging as an ideal material for work both aesthetic areas as in areas of need for mechanical support with high functional load.

The clinical care of patients with epilepsy (EP) associated with intellectual disability (ID) represents a challenge for the stomatologist because of its difficult behavioral management. These patients will require alternatives to carry out a successful dental treatment. General anesthesia (AG), is an alternative to the failure of behavioral management techniques, existence of systemic commitment that warrants it, specialized medical access distant from the place of residence or due to particular circumstances of each case. We present the case of a 27-year- old male patient, with a diagnosis of EP associated with ID, of difficult behavioral management treated under general anesthesia in the Special Patients Stomatology service of the Peruvian University Cayetano Heredia. Objective: This article seeks to present a review of the literature and Comprehensive Dental Treatment under general anesthesia of a patient with Epilepsy associated with moderate Intellectual Disability. Conclusions: Patients with these underlying pathologies are prone to present deterioration of the oral organ, so they will require constant stomatological benefits. Due to the low collaboration of this type of patients, the AG should be considered as an alternative to provide the TOI in a single operative act.

Dental erosion is the irreversible loss of the surface of the enamel or dentin, due to frequent exposure of non- bacterial acids. Although certain fruit juices have erosive potential in vitro, there is no conclusive evidence in this regard. Objective: To evaluate in situ the erosive potential of Amazonian fruit juices on dental enamel. Material and methods: The Vickers surface microhardness (VMH) of dental enamel was evaluated in situ after exposure to drinks Physalis Peruviana (aguaymanto), Averrhoa Carambola (carambola), Myrciaria Dubia (camu camu), Coca cola (positive control) and distilled water (negative control). Fifteen volunteers (18 to 30 years) participated who wore palatal appliances to reproduce the storage medium. Each one containing 6 enamel blocks. The appliances were exposed to the different drinks 4 times a day (9:00 am, 11: 00 am, 13:00 pm and15:00 pm) for 5 minutes during 5 days. For each erosive cycle, they were exposed to two drinks, immediately the palatal devices were repositioned in the participants’ mouth. There was an 8-day washout period between each cycle. The difference in VMH before and after exposure was calculated. The ANOVA/Tukey analysis was used to determine the differences between beverages in the SPSS 19 program, with a significance level of 0.5%. Results: The four experimental groups decreased enamel VMH (p<0.05) without significant difference between them. Conclusions: The juices based on camu camu, aguaymanto and carambola are potentially erosive.

Objective: The objective of this study is to update scientific knowledge about OPMDs, emphasizing epidemiological data, clinical appearance, symptomatology, differential diagnosis and therapeutic management, as well as highlighting the role of the general dentist in the clinical examination. Material and methods: A literature search was carried out, making use of the keywords “Leukoplakia”, “Erythroplasia”, “Cheilitis”, “Nevus, Pigmented”, “Oral Submucous Fibrosis” and “Lichen Planus”. Prioritizing articles published in the last 5 years on the scientific databases “Medline”, “Pubmed” and “SciELO”. Results: As a result of the search, 165 articles were obtained, which were carefully reviewed to preserve only those that were dedicated to describe, compare or treat lesions with malignant potential, including relevant data such as epidemiology, clinical appearance, symptomatology, differential diagnosis and management. therapeutic. In this way, the study was limited to 41 articles. Conclusions: By taking preventive measures, as well as through a clinical examination of soft tissues, early detection of potentially malignant disorders can be facilitated. The removal of suspicious lesions or a control of their carcinogenic conditions can largely prevent the development of malignant tumors.

Calcium silicate-based cements are bioactive materials, which have the capacity to release a greater number of calcium and hydroxyl ions, providing some advantages like an increased antimicrobial and remineralise activity, increasing the pulp treatments longevity. Theracal LC is a calcium silicate-based cement that has as an advantage its easy application, comparing to others bioactive cements. In this case report, Theralcal LC was used as a cavity liner. At clinical examination teeth 36 and 35 exhibited diagnosis of Dental caries; 36 with a cavitated lesion and 35 with a lesion adjacent to a previous restoration; and pulp diagnosis, Sound Pulp, for both tooth pieces. Direct restorations were made with composite resin in tooth pieces 36 and 35, considering the following steps: selective etching, self-etch adhesive system, calcium silicate-based cement and Bulk-fill resin composite.
