ABSTRACT
BACKGROUND: Military life leads to a great personal sacrifice and labor in the aircrew because they are constantly subjected to innumerable activities which have a great work pressure; therefore, the aim of this study was to determine the level of work stress associated with bruxism in the aircrew of the Peruvian Air Force. METHODS: This was a cross-sectional study. A total of 204 crew members of the Peruvian Air Force from the Air Group were surveyed, and the stomatological clinical inspection was carried out. Each crew member was evaluated using the validated International Labor Organization-World Health Organization (ILO-WHO) Work Stress Scale, and clinical records were used to diagnose bruxism using the Smith and Knight wear index. RESULTS: It was found that 93.7% (n = 191) of the crew members were men and 6.3% (n = 13) were women; and the percentage of intermediate-level stress was found to be high in the grade of non-commissioned officers, whereas in the officer grade, the level of stress was low. There was also a statistically significant association between the variables military grade, sex, and age group. The sub-officers presented a higher percentage in the category "with bruxism", while in the rank of officers the category of "non-bruxism" was the most prevalent. CONCLUSIONS: This study showed a statistically significant association between the variable bruxism and the level of work stress between the military aviators of the Peruvian Air Force (p<0.001).
ABSTRACT
AIM: The aim of this study is to assess the epidemiological profile of 12- to 16-year-old adolescents with Down syndrome in the Special Basic Education Center in Lima-Peru. MATERIALS AND METHODS: A cross-sectional descriptive study was performed, where the epidemiological profile was determined through the DMF-T index, oral hygiene index (OHI), and the gingival index from Silness and Löe. A sample of 107 adolescents with Down syndrome in a Peruvian rural population were considered who were evaluated with the formula of proportion estimation, of which 48 (44.8%) were females and 55 (59%) males. RESULTS: Patients with mild to moderate Down syndrome were with a caries prevalence of 42 and 27.1%, respectively. Likewise, class III malocclusion was present in 42.9 and 25.2%. The most prevalent OHI was the regular category with 66.2%. RESULTS: Patients with mild to moderate Down syndrome were with a caries prevalence of 42 and 27.1%, respectively. Likewise, class III malocclusion was present in 42.9 and 25.2%. The most prevalent OHI was the regular category with 66.2%. CONCLUSION: It was evident in mild Down syndrome adolescents, a higher prevalence of the indexes: dental caries, malocclusion, periodontal disease, and oral hygiene, moderate to severe.

OBJECTIVES: To develop and formulate a new experimental dentifrice with and without fluoride based on the peel and the fruit of the Passiflora mollissima (tumbo) and also to evaluate its antimicrobial activity against seven bacterial strains. METHODS: The sample was calculated using the mean comparison formula, obtaining wells (n = 12) for each of the strains evaluated: S. mutans, E. faecalis, Actinomyces, Lactobacillus, C. albicans, S. sanguinis, and S. oralis. The antibacterial activity of the dentifrice was evaluated by the direct contact technique. RESULTS: It was found that the highest antimicrobial activity was only present in pulp-based dentifrices against strains of S. mutans 21.0 ± 1.8, E. faecalis 16.3 ± 3.9, Actinomyces 22.1 ± 1.3, and Lactobacillus 21.0 ± 1.3. However, in comparison with other strains such as C. albicans, S. sanguinis, and S. oralis, the peel-based dendrifrice of Passiflora mollissima obtained the highest antimicrobial activity. CONCLUSION: The experimental dentifrice based on Passiflora mollissima had an antibacterial effect against the seven microbial strains during the first 24 and 48 hours.
ABSTRACT
AIM: The antimicrobial activity of Passiflora mollissima is largely due to its aliphatic and aromatic hydrocarbons, terpenes, alkaloids, ketones, esters, alcohols, and lactones. The objective of this research was to evaluate the antimicrobial activity of the compounds in the Passiflora mollissima (Tumbo) fruit and leaves included also on cultured strains of the microorganisms Streptococcus mutans, Streptococcus oralis, Streptococcus sanguinis and Candida albicans. MATERIALS AND METHODS: Antimicrobial activity was analyzed by the disk diffusion method and evaluated in terms of their zones of inhibition. The cytotoxic activity of these compounds was determined in a bioassay involving sea urchin eggs (Tetrapygusniger) in which the inhibition percentage of artificially fertilized ovules was equivalent to their cytotoxic activity after 26 hours. RESULTS: This study demonstrated the antimicrobial activity of ethanolic Passiflora mollissima extract against the cultured strains of Streptococcus mutans, Streptococcus oralis, and Streptococcus sanguinis with zones of inhibition after the incubation period. CONCLUSION: There was no evidence of activity against the pathogenic Candida albicans, which demonstrates a null antifungal capacity of the evaluated extracts. However, cytotoxic activity was found, and the compounds led to the complete inhibition of 100% of sea urchin ovules after 26 hours of exposure. CLINICAL IMPORTANCE: The results of the study serve as a guide. in the industrial use of this natural resource "tumbo" due to the discovery of a potential medicine based on this plant that would be a great development in the field of antimicrobial therapies.

AIM: To determine the epidemiological profile of oral diseases in a marginal urban Peruvian population. METHODS: A 9-year retrospective study was conducted, analysing 18,639 clinical records from the María Auxiliadora Hospital between 2006 and 2015 with diagnoses of oral lesions using ICD-10 criteria. Clinical records were analysed for sex, tumour, periapical abscess and sinus, cysts of the oral region, other lesions of the oral mucosa and cavity, gingivitis and periodontal disease, dentofacial anomalies, diseases of pulp, etc. RESULTS: Of 18,639 cases, the prevalence was higher in women for the following pathologies: unspecified dental caries (30.6%); impacted tooth in the category of disorders of tooth development and eruption (2.0%); pulpitis (6.8%) in the category of diseases of pulp and periapical tissues; temporomandibular joint (TMJ) disorders (1.5%) in the category of dentofacial anomalies; acute gingivitis (7.5%); radicular cyst (0.3%) in the category of cysts of the oral region; and periapical abscess without sinus (2.0%). CONCLUSIONS: We found a significant association between sex and different types of dental caries, disturbances in tooth eruption, diseases of pulp and periapical tissues, and dentofacial anomalies. The study also shows a statistically significant association between sex and gingivitis, periodontal disease, and periodontal abscess and sinus.
