RESUMEN

BACKGROUND: The most rapidly increasing medical aesthetic procedures for facial antiaging comprise nonenergy and injectable treatments. Currently, standards for skin care before, during, and after nonenergy and injectable treatments are lacking. The algorithm on supportive skin care for facial antiaging nonenergy and injectable treatments aims to stimulate healing, reduce downtime, and improve comfort and treatment outcomes.  Methods: A panel of 7 global physicians employed a modified Delphi method and reached a consensus on an algorithm for supportive skin care for nonenergy and injectable antiaging treatments based on the best available evidence and the panel members’ clinical experiences and opinions. RESULTS: The algorithm has a pretreatment (starts 2 – 4 weeks before the procedure) and treatment or ongoing (day of treatment) section, followed by care after the procedure (0 – 7 days) and follow-up care (1 – 4 weeks after the procedure). Applying a broad-spectrum sunscreen with an SPF 30 or higher, combined with protective measures, such as wearing a wide-brimmed hat and sunglasses, is recommended to protect the face from sun exposure. Dyschromia is a significant concern for those with richly pigmented skin. Clinicians may recommend skin care using a gentle cleanser and moisturizer containing vitamins C and E, retinoid, or other ingredients, such as niacinamide, kojic acid, licorice root extract, azelaic acid, and tranexamic acid, depending on the patient's facial skin condition. CONCLUSION: Nonenergy and injectable procedures combined with skin care or topical treatments may improve outcomes and patient satisfaction. Topical antioxidants and free radical quenchers can combat photodamage and may offer a safe alternative to topical hydroquinone.    J Drugs Dermatol. 2024;23(4):     doi:10.36849/JDD.7918.

RESUMEN

BACKGROUND: Medical aesthetic procedures for facial antiaging with laser and energy-based devices (EBDs) are rapidly increasing, but standards integrating skincare before, during, and after these treatments are lacking. The algorithm for integrated skin care for facial antiaging treatment with EBDs aims to stimulate healing, reduce downtime, and improve comfort and treatment outcomes. METHODS: A panel of 8 global physicians employed a modified Delphi method and reached a consensus on the algorithm integrating skincare based on the best available evidence, the panel's clinical experience, and opinions. RESULTS: The algorithm has a pretreatment (starts 2 - 4 weeks before the procedure) and treatment (day of treatment) section, followed by care after the procedure (0 - 7 days) and follow-up care (1 - 4 weeks after the procedure or ongoing). Applying a broad-spectrum sunscreen with an SPF 50 or higher, combined with protective measures such as wearing a wide-brimmed hat and sunglasses, is recommended to protect the face from sun exposure. Dyschromia is a significant concern for those with skin of color (SOC). Clinicians may recommend skincare using a gentle cleanser and moisturizer containing vitamins C and E, retinoid, or other ingredients such as niacinamide, kojic acid, licorice root extract, azelaic acid, and tranexamic acid, depending on the patient's facial skin condition. CONCLUSION: Medical aesthetic procedures for facial antiaging with EBDs integrating skincare or topical treatments may improve outcomes and patient satisfaction. Topical antioxidants and free radical quenchers can combat photodamage and may offer a safe alternative to topical hydroquinone.  J Drugs Dermatol. 2024;23(5):353-359.     doi:10.36849/JDD.8092.

RESUMEN

BACKGROUND: People with Sensory Disabilities (PcDS) face barriers for equal access to health care. Thus, health centers require adjustments to comply with equal access that allows an universal coverage of care. AIM: To characterize the adjustments for the care of PcDS in primary health centers in Concepción, Chile. MATERIAL AND METHODS: Cross-sectional study using data obtained through a questionnaire to key informants or via Transparency Law, and direct observation. The variables were subdivided into four categories, namely infrastructure, communication, skills, and environment. RESULTS: The analyzed health centers have a high proportion of general adjustments of their physical settings. However, there is a lack of specific adjustments for deaf and blind people, especially communicational ones. CONCLUSIONS: There is a paucity of adjustments for the health care of PcDS in the analyzed health centers. This deficiency underscores the barriers faced by PcDS for receiving care in the Chilean public health system.

RESUMEN

Theophylline is used in canine medicine for the management of chronic bronchitis and bradyarrhythmias, yet no species-validated commercial products are available. This study reports the single-dose and multidose pharmacokinetics and safety of a modified, compounded theophylline (MCT) product readily available from a well-established, USP-compliant compounding pharmacy, which may be a suitable and reliable source for theophylline for dogs. Eleven dogs underwent serial plasma theophylline measurement following 10 mg/kg MCT PO. After a 7 days washout, dogs received 10 mg/kg MCT PO q12h and serial plasma theophylline quantification was repeated after the ninth dose. Dogs were monitored for potential adverse effects. For the nine dogs that completed the study, plasma theophylline concentrations were between 5 and 30 µg/ml for 91 +/- 15% of the dosing interval. There was no significant difference in half-life between single-dose and multidose administration. The most common adverse effects reported were mild and included agitation, excitement, and increased activity. The results of this study support the use of 10 mg/kg MCT administered twice daily as a starting dosage in dogs. This regimen appears safe, achieves appropriate plasma drug concentrations in most dogs, and does not cause significant changes in pharmacokinetic properties at steady state. Because compounded drugs do not undergo consistent testing for identity, quality, strength, purity, and stability, results of research described in reports using compounded products may not be reproducible.

RESUMEN

Visual or hearing disabilities account for 20% of people reporting some sort of disability. We performed a literature review about the interaction that people with visual or hearing disabilities have with the health care system. We found that these people report a lower quality of life and have a higher frequency of physical and psychological ailments. They also have difficulties to obtain an adequate health care and report a paucity of trained professionals to take care of them.

RESUMEN

Leg telangiectasias and reticular veins are a common complaint affecting more than 80% of the population to some extent. To date, the gold standard remains sclerotherapy for most patients. However, there may be some specific situations, where sclerotherapy is contraindicated such as needle phobia, allergy to certain sclerosing agents, and the presence of vessels smaller than the diameter of a 30-gauge needle (including telangiectatic matting). In these cases, transcutaneous laser therapy is a valuable alternative. Currently, different laser modalities have been proposed for the management of leg veins. The aim of this article is to present an overview of the basic principles of transcutaneous laser therapy of leg veins and to review the existing literature on this subject, including the most recent developments. The 532-nm potassium titanyl phosphate (KTP) laser, the 585-600-nm pulsed dye laser, the 755-nm alexandrite laser, various 800-983-nm diode lasers, and the 1,064-nm neodymium yttrium-aluminum-garnet (Nd:YAG) laser and various intense pulsed light sources have been investigated for this indication. The KTP and pulsed dye laser are an effective treatment option for small vessels (<1 mm). The side effect profile is usually favorable to that of longer wavelength modalities. For larger veins, the use of a longer wavelength is required. According to the scarce evidence available, the Nd:YAG laser produces better clinical results than the alexandrite and diode laser. Penetration depth is high, whereas absorption by melanin is low, making the Nd:YAG laser suitable for the treatment of larger and deeply located veins and for the treatment of patients with dark skin types. Clinical outcome of Nd:YAG laser therapy approximates that of sclerotherapy, although the latter is associated with less pain. New developments include (1) the use of a nonuniform pulse sequence or a dual-wavelength modality, inducing methemoglobin formation and enhancing the optical absorption properties of the target structure, (2) pulse stacking and multiple pass laser treatment, (3) combination of laser therapy with sclerotherapy or radiofrequency, and (4) indocyanin green enhanced laser therapy. Future studies will have to confirm the role of these developments in the treatment of leg veins. The literature still lacks double-blind controlled clinical trials comparing the different laser modalities with each other and with sclerotherapy. Such trials should be the focus of future research.

RESUMEN

Marek's disease (MD), caused by gallid alphaherpesvirus 2 (GaAHV2) or Marek's disease herpesvirus (MDV), is a devastating disease in chickens characterized by the development of lymphomas throughout the body. Vaccine strains used against MD include gallid alphaherpesvirus 3 (GaAHV3), a non-oncogenic chicken alphaherpesvirus homologous to MDV, and homologous meleagrid alphaherpesvirus 1 (MeAHV1) or turkey herpesvirus (HVT). Previous work has shown most of the MDV gC produced during in vitro passage is secreted into the media of infected cells although the predicted protein contains a transmembrane domain. We formerly identified two alternatively spliced gC mRNAs that are secreted during MDV replication in vitro, termed gC104 and gC145 based on the size of the intron removed for each UL44 (gC) transcript. Since gC is conserved within the Alphaherpesvirinae subfamily, we hypothesized GaAHV3 (strain 301B/1) and HVT also secrete gC due to mRNA splicing. To address this, we collected media from 301B/1- and HVT-infected cell cultures and used Western blot analyses and determined that both 301B/1 and HVT produced secreted gC. Next, we extracted RNAs from 301B/1- and HVT-infected cell cultures and chicken feather follicle epithelial (FFE) skin cells. RT-PCR analyses confirmed one splicing variant for 301B/1 gC (gC104) and two variants for HVT gC (gC104 and gC145). Interestingly, the splicing between all three viruses was remarkably conserved. Further analysis of predicted and validated mRNA splicing donor, branch point (BP), and acceptor sites suggested single nucleotide polymorphisms (SNPs) within the 301B/1 UL44 transcript sequence resulted in no gC145 being produced. However, modification of the 301B/1 gC145 donor, BP, and acceptor sites to the MDV UL44 sequences did not result in gC145 mRNA splice variant, suggesting mRNA splicing is more complex than originally hypothesized. In all, our results show that mRNA splicing of avian herpesviruses is conserved and this information may be important in developing the next generation of MD vaccines or therapies to block transmission.

RESUMEN

OBJECTIVE: Determine and measure the association of social factors and health conditions with worse capacity and performance levels. METHODS: Dependent variables consisted of performance and capacity; independent variables comprised age, gender, level of education, personal income, and health conditions. Means (95%CI) of performance and capacity were presented according to the independent variables. Generalized linear models, using a mutual adjustment for all variables considered statistically significant (p < 0.05), measured the associations between each exposure and outcomes. Study population included 12,265 individuals. RESULTS: Older women with lower education and income levels and with some health condition showed the worst performance and capacity. CONCLUSION: Results showed that the capacity and performance levels of the Chilean population changed according to social demographic characteristics and health conditions.

RESUMEN

OBJECTIVES: An altered retinol metabolism might play a role in the development of nonalcoholic fatty liver disease (NAFLD). Tocopherols (TF) modulate metabolic pathways and have been proposed as a complementary treatment of obesity-induced metabolic alterations. Moreover, there is evidence suggesting that TF may modulate retinol metabolism. The aim of this study was to evaluate whether the dietary supplementation of α- and γ-TF modulates the expression of hepatic retinaldehyde dehydrogenases, RALDH1, RALDH2, and RALDH3 (involved in retinol metabolism) and, lipogenic factors sterol regulatory element binding protein-1c (SREBP-1c) and cluster differentiation 36 (CD36) in an animal model of diet-induced NAFLD. METHODS: Male C57BL/6J mice were divided into four groups: a control diet (CD) group (10% fat, 20% protein, 70% carbohydrates); a CD + TF group (α-tocopherol: 0.7 mg·kg·d-1, γ-tocopherol: 3.5 mg·kg·d-1); a high-fat diet (HFD) group (60% fat, 20% protein, 20% carbohydrates); and a HFD + TF group (0.01 mL·g body weight·d-1), for 12 wk. General parameters (body-adipose tissue weight, glucose-triacylglyceride serum levels), liver steatosis (histology, liver triacylglycerides content), and hepatic RALDH1, RALDH2, RALDH3, SREBP-1c and CD36 (qPCR, quantitative polymerase chain reaction; IHQ, immunohistochemistry) were measured. RESULTS: TF supplementation in HFD-fed mice decreased the presence of lipid vesicles (90%) and total lipid content (75%) and downregulated the expression of RALDH1, RALDH3, SREBP-1c, and CD36. CONCLUSIONS: The present study demonstrated that α- and γ-TF (1:5 ratio) might play a role in modulating retinol metabolism in the prevention of NAFLD induced by a HFD.

RESUMEN

BACKGROUND: Acne is a chronic disease that affects the pilosebaceous follicle and is characterized by the presence of non-inflammatory and/or inflammatory lesions, affecting both adolescents and adults. Inflammatory acne lesions are capable to increase their melanin production and promote a post-inflammatory hyperchromia. AIMS: To assess the efficacy of a serum containing dioic acid, glycolic acid, salicylic acid, LHA, citric acid, and HEPES in treating post-inflammatory hyperpigmentation and controlling skin oiliness in Brazilian patients with acne vulgaris. PATIENTS/METHODS: A single-center, prospective, open-label clinical study included 42 subjects, from both genders, presenting acne (grade I or II), oily skin and a clinical diagnosis of acne post-inflammatory hyperpigmentation. The study was conducted for 56 days, with clinical (skin quality and the number of post-inflammatory hyperchromic lesions) and instrumental (Sebumetry) evaluations after 7, 28, and 56 days of treatment. Standardized pictures were obtained using a VISIA-6® device. RESULTS: A significant decrease in the grade of post-inflammatory hyperchromic lesions was observed after 28 and 56 days, while the number of lesions decreases by 29.4% after 56 days (p < 0.001). Sebumetry values showed a significant decrease of 30.7% in the oiliness after 7 days of treatment, and then stable during the study conduction period of 56 days (p < 0.001 for all measurements). CONCLUSIONS: The daily treatment using the investigational product showed an interesting decrease both in the grade and the number of post-inflammatory hyperchromia acne lesions after 56 days, and in the oiliness after 7 days, being stable for all study period.

RESUMEN

Neuregulins (NRGs) are a family of signaling proteins that bind to receptor tyrosine kinases of the ErbB family (ErbB2 to ErbB4), which can homo- or heterodimerize depending on their structural features and cell type. Many studies have proposed that decreased NRG levels are a common characteristic of obesity. In liver and adipose tissue, the increase in NRG expression has protective effects against obesity. However, it is still unknown whether ErbBs expression is altered in this pathology. We hypothesized that high fat diet-induced obesity downregulates ErbB receptors expression in obese mice compared to normal weight mice. Males C57BL/6 mice (n=6-7 for each group) were fed for 12 weeks and divided into: (i) control diet (CD; 10%-kcal fat, 20%-kcal protein, 70%-kcal carbohydrates), and (ii) high fat diet (HFD; 60%-kcal fat, 20%-kcal protein, 20%-kcal carbohydrates). General parameters and ErbBs expression (qPCR, immunohistochemistry and Western blot) were evaluated. We observed a significant increase in final body weight (47%), adipose tissue to body weight ratio (244%) and HOMA-IR (69%), among other parameters, in obese mice. In HFD group significantly decreased ErbB2 (48%) and ErbB3 (66%) mRNA levels in liver (no change in ErbB4), and ErbB2 (43%), ErbB3 (76%) and ErbB4 (35%) in adipose tissue, compared to CD. Furthermore, ErbB2 and ErbB3 protein levels decreased significantly in HFD group compared to the CD in liver. Therefore, our results suggest that HFD-induced obesity significantly decreases ErbBs expression in liver and adipose tissue in this murine model, that may be associated with alterations in the NRG pathway in obese mice.


Las neuregulinas (NRGs) son una familia de proteínas de señalización que se unen a receptores tirosina quinasas de la familia ErbB (ErbB2 a ErbB4), que pueden homo- o heterodimerizar dependiendo de sus características estructurales y del tipo celular. Estudios han propuesto que la disminución de los niveles de NRG es una característica común de la obesidad. En el hígado y el tejido adiposo (TA), el aumento de la expresión de NRG tiene efectos protectores contra la obesidad. Sin embargo, aún se desconoce si la expresión de ErbBs está alterada en esta patología. Nuestra hipótesis es que la obesidad inducida por una dieta alta en grasas (DAG) disminuye la expresión de los ErbB en ratones obesos. Ratones machos C57BL/6 (n=6-7 para c/grupo) fueron alimentados durante 12 semanas y divididos en: (i) dieta control (DC; 10%-kcal grasa, 20%-kcal proteína, 70%-kcal carbohidratos), y (ii) DAG (60%-kcal grasa, 20%-kcal proteína, 20%-kcal carbohidratos). Se evaluaron los parámetros generales y la expresión de ErbBs (qPCR, inmunohistoquímica y Western blot). Observamos un aumento significativo del peso corporal final (47%), de la relación tejido adiposo/peso corporal (244%) y del HOMA-IR (69%), entre otros parámetros, en ratones obesos. En este grupo disminuyó significativamente los niveles de ARNm de ErbB2 (48%) y ErbB3 (66%) en el hígado (sin cambios en ErbB4), y de ErbB2 (43%), ErbB3 (76%) y ErbB4 (35%) en el TA. Además, los niveles de proteína ErbB2 y ErbB3 disminuyeron significativamente, en comparación con el grupo DC en el hígado. Nuestros resultados sugieren que la obesidad inducida por DAG disminuye significativamente la expresión de ErbBs en el hígado y el TA, que puede estar asociado con alteraciones en la vía NRG en ratones obesos.

RESUMEN

Objective: Characterize HIV/AIDS Social stigma towards people with HIV/AIDS in a sample of dentistry students from Concepción. Materials and methods: Cultural adaptation and pre-test were developed for the Stigma and HIV/AIDS Scale in dental students. Researchers collected the data from the instrument, demographic (sex/age), and academic information (course/training in HIV/AIDS, knowing a person with HIV/AIDS, provision of dental services to people living with HIV/AIDS [PLHIV]). To characterize the sample, univariate and bivariate descriptive statistics were performed with absolute and relative frequencies; the reliability of the scale was assessed with Cronbach's alpha; the relationship between the quantitative and ordinal variables was analyzed with the Spearman correlation coefficient. Results: The final sample comprised 138 dental students, whereas most of them reported not having training in HIV/AIDS nor providing dental services to PLHIV. Stigma and HIV/AIDS Scale showed good reliability. Two items expressing that PLHIV must disclose their condition to health professionals so they can take precautions have the highest values. A weak inverse correlation was found between Stigma and the variables age and course. Conclusions: Dental school students from Universidad of Concepción have a low social stigma towards people with HIV/AIDS. Items regarding professional practice showed higher stigma levels.

RESUMEN

Nematode strains of the entomopathogenic family Steinernematidae differ in their ability to infect insects at different temperatures. Survival and infectivity of infective juveniles (IJs) of Steinernema rarum (OLI) were studied after their storage at 23+/-2 degrees C and at 5+/-1 degrees C. Survival at 23+/-2 degrees C was always above 95%. At 5+/-1 degrees C, survival decreased at week 5, but infectivity did the same after week 2. Unlike other steinernematids, both infectivity and survival of IJs would be higher for S. rarum (OLI) when stored at 23+/-2 degrees C.

RESUMEN

The educational environment affects dental students' well-being and academic achievement, with unclear impact from clinical instructors on burnout levels. This study is aimed to determine the impact of students' perception about their clinical instructors in its burnout levels in a sample of Chilean dental students. Methods: A cross-sectional study was conducted among fourth and fifth-year dental students at the University of Concepción (Chile), collecting data on various variables including demographics, effective teaching hours, instructor treatment, knowledge delivery, student appreciation, and burnout assessed using Maslach's Burnout Inventory (MBI). Data were gathered through a self-administered survey and analyzed using STATA 10/SE software (p<0.05). Results: One-hundred and seventy students participated, high levels of emotional exhaustion (51.76%), depersonalization (56.47%), and personal accomplishment (60.59%) were found. Female students (p=0.0008), those who perceive inadequate treatment from instructors towards patients (p=0.0496), and those who rate the instructor as obstructionist (p=0.0208) reported higher levels of emotional exhaustion. 5th year students (p=0.0142), students who perceive indifferent treatment from instructors towards students (p=0.0002), and those who rate the instructor as obstructionist (p=0.0026) exhibited higher levels of depersonalization. 4th year students (p=0.0475) and those who perceive indifferent treatment from instructors towards students (p=0.0221) showed lower levels of personal accomplishment. There was a correlation between depersonalization and effective teaching hours (rho=-0.2166, p=0.0046). Conclusion: Students' perception about their clinical instructors as indifferent towards the students, obstructionist in the teaching process, with inadequate treatment towards the patients, and less effective teaching hours is associated with higher students' burnout levels.

RESUMEN

BACKGROUND: Oral health plays a crucial role in general health, quality of life and well-being of pregnant women and their newborns. In Chile, pregnant women have dental care guaranteed by law. However, due to the lack of previous epidemiological studies on the benefits of this guarantee, it is necessary to describe this situation and evaluate the need to change the methods of providing dental services. OBJECTIVES: The objective of this study was to describe the pattern of providing dental benefits resulting from the Explicit Health Guarantee - Integral Oral Health in Pregnant Women (GES-SOIE) program to pregnant women attending the Juan Soto Fernández Family Health Center, Concepción, Chile, in 2014-2015. MATERIAL AND METHODS: A cross-sectional study of the electronic dental records of patients admitted to GES-SOIE was conducted. The variables studied were sociodemographic data, dental chair hours, non-attendance, treatment completion, and the type of referral to secondary healthcare (SHC). RESULTS: Of 233 pregnant women, 65.2% were registered for non-attendance, 21.2% required referral to SHC and 76.4% completed their treatment. When performing logistic regression, it was found that for each non-attendance the chance of not completing the treatment increased 1.4 times. CONCLUSIONS: The level of non-attendance and opting out of the treatment in pregnant women is high, which hinders the proper functioning and effectiveness of GES-SOIE.

RESUMEN

BACKGROUND: Organic silicon plays an important role in dermal structure by promoting neocollagenesis. Thus, the supplementation of silicon in a highly bioavailable form can be used for skin rejuvenation. AIMS: This study aimed to evaluate skin changes associated with the use of ortho-silicic acid stabilized by hydrolyzed collagen. PATIENTS/METHODS: Patients were randomized to receive 600 mg of ortho-silicic acid stabilized by hydrolyzed collagen (group 1, n = 11) or placebo (group 2, n = 11) to be taken 15 minutes before breakfast for 90 days. Clinical, photographical, and patients' subjective evaluations were conducted. RESULTS: A total of 22 patients were included. Clinical evaluations demonstrated changes in skin texture, firmness, and hydration statistically superior in group 1. Brightness, firmness, and overall appearance showed trends for a difference favoring group 1 according to patients' subjective evaluations. Objective images showed no statistical differences. No side effects, hypersensitivity, or systemic symptoms were observed in group 1. Treatment satisfaction in group 1 reached 80%. CONCLUSIONS: Ortho-silicic acid stabilized by hydrolyzed collagen in a daily dose of 600 mg showed positive results in skin rejuvenation according to clinical evaluation in firmness, hydration, and skin texture. Further studies with larger and representative samples should be conducted to confirm our results.

RESUMEN

The effects of poaching on wildlife have been widely studied in conservation biology and can be heterogeneous, particularly on ungulates. These effects can be estimated through different methodologies whose use depends on several conditions such as Flight-initiation distance (FID). Our objectives were: 1- to evaluate whether poaching affects the FID and group structure of a guanaco (Lama guanicoe) population in a high cold desert in San Juan (Argentina); 2- to assess whether habitat structure (slope and vegetation cover) influences FID and group structure in this population. The study area included a site with poaching (unprotected area), and a site without poaching (protected area). We recorded 100 groups of guanacos: 70 in the protected and 30 in the unprotected area. FID and group size were greater in the unprotected than in the protected area, whereas proportions of group categories (with offspring, without offspring and solitary) were similar between areas. Besides, in relation to habitat structure, FID increased when vegetation cover decreased. On the other hand, FID and group size were not affected by slope. Our study shows that guanacos respond to poaching pressure as do other ungulate species, and that other factors such as vegetation cover also affect this behavior. Managers should be aware when interpreting FID due to its relation to habitat structure; the guanaco appears to assume greater risk (lower FID) in areas with high vegetation cover.

RESUMEN

BACKGROUND: People with Sensory Disabilities (PcDS) face barriers for equal access to health care. Thus, health centers require adjustments to comply with equal access that allows an universal coverage of care. AIM: To characterize the adjustments for the care of PcDS in primary health centers in Concepción, Chile. Material and Methods: Cross-sectional study using data obtained through a questionnaire to key informants or via Transparency Law, and direct observation. The variables were subdivided into four categories, namely infrastructure, communication, skills, and environment. RESULTS: The analyzed health centers have a high proportion of general adjustments of their physical settings. However, there is a lack of specific adjustments for deaf and blind people, especially communicational ones. Conclusions: There is a paucity of adjustments for the health care of PcDS in the analyzed health centers. This deficiency underscores the barriers faced by PcDS for receiving care in the Chilean public health system.

RESUMEN

Abstract Objective: To identify the factors associated with Oral Health-Related Quality of Life (OHRQoL) in preschool children of Concepción, Chile. Material and Methods: A cross-sectional study was conducted in a sample of enrolled preschoolers who attend public schools in Concepción, Chile. To measure OHRQoL, the chilean version of the Early Childhood Oral Health Impact Scale (ECOHIS) was used; sociodemographic variables of the children and their parents were also recorded, as well as variables regarding the last visit to the dentist. To determine differences in the ECOHIS score for categorical variables, ANOVA and t-test were used, while Pearson's r was used to correlate ECOHIS with quantitative variables (p<0.05). Results: A total of 175 children were surveyed, with a distribution of 89 boys and 86 girls aged 56-to-79 months. The total score of the ECOHIS had a mean of 4.48 ±5.96, with a score between 0-38. Statistically significant associations were with parent's educational attainment (r=−0.159), dmft (r=0.380), OHI-S debris (r=0.174) and reason for the last visit to the dentist, the highest average in the ECOHIS scores was registered in the urgency reason. Conclusion: Oral health status, dental service utilization and educational level are associated with the OHRQoL of preschoolers of Concepción (AU).
