Understanding the Dynamics of Inflammatory Cytokines in Endodontic Diagnosis: A Systematic Review.

The primary aim of this literature review is to delineate the key inflammatory cytokines involved in the pathophysiology of pulp inflammation. By elucidating the roles of these cytokines, a deeper comprehension of the distinct stages of inflamed pulp can be attained, thereby facilitating more accurate diagnostic strategies in endodontics. The PRISMA statement and Cochrane handbook were used for the search strategy. The keywords were created based on the review question using the PICO framework. The relevant studies were meticulously assessed according to predefined inclusion and exclusion criteria for this systematic review. A rigorous quality checklist was implemented to evaluate each included study, ensuring scrutiny for both quality and risk-of-bias assessments. The initial pilot search conducted on PubMed, Scopus, Cochrane, and WoS databases yielded 9 pertinent articles. Within these articles, multiple cytokines were identified and discussed as potential candidates for use in endodontic diagnosis, notably including IL-8, IL-6, TNF-α, and IL-2. These cytokines have been highlighted due to their significant roles in the inflammatory processes associated with pulp pathology. The identification of specific inflammatory cytokines holds promise for enhancing endodontic diagnostic procedures and exploring diverse treatment modalities. However, the current body of research in this area remains limited. Further comprehensive studies are warranted to fully elucidate the potential of cytokines in refining diagnostic techniques in endodontics.

Assessment of the Penetration of an Endodontic Sealer into Dentinal Tubules with Three Different Compaction Techniques Using Confocal Laser Scanning Microscopy.

Adequate root canal sealing is essential for the success of endodontic treatment. There are numerous techniques available; identifying simple and efficient techniques is important to provide good patient care. The purpose of the study was to compare the maximum penetration depth and the percentage of sealant penetration of an endodontic sealer into dentine tubules using cold lateral condensation, continuous wave, and hybrid techniques, and to contrast the effectiveness of two different tapered gutta-percha master cones (0.02 and 0.04). A sample of sixty single root teeth was used. Six experimental groups were formed from the three filling techniques and the two tapered master cones. Images were acquired using a confocal laser scanning microscope. In the apical root third, the penetration percentage was higher in the hybrid compared with the continuous wave technique. The results indicated a higher penetration depth of hybrid compared with cold lateral condensation in the middle and coronal thirds, and in the apical third, a higher penetration was identified in the hybrid group compared with the continuous wave group. No significant differences in penetration were found comparing 0.02 with 0.04 taper gutta-percha groups. The coronal cross-sections presented a higher penetration than the apical third sections. In conclusion, the hybrid technique a had higher maximum sealer penetration than the continuous wave in the apical third, and the coronal third hybrid and continuous wave had a higher penetration than cold lateral condensation.

Depression symptoms and sweet foods consumption in Mexican college men: the role of emotional eating / Síntomas de depresión y consumo de alimentos dulces en un grupo de varones universitarios mexicanos: el papel de la alimentación emocional

Objective: to evaluate the association between depression symptoms and frequency of unhealthy food consumption, and to explore the mediation effect of emotional eating in this relationship in college men. Method: a cross-sectional study was performed on 764 men at a public university in Mexico City. To assess emotional eating (EE), a validated Spanish-language version of the Eating and Appraisal Due to Emotions and Stress Questionnaire (EADES) was applied. Depression symptoms were evaluated using the scale elaborated by the Center for Epidemiologic Studies (CES-D) and a Questionnaire of Frequency of Food Consumption was used to measure frequency of food consumption. Path and mediation analysis were applied. Results: one-fifth (20.42 %) of college men reported depression symptoms (CES-D ≥ 16). Students with depression symptoms had a higher mean EE score (p < 0.001), a higher frequency of fried food (p = 0.049), sweetened beverages (p = 0.050), and sweet foods consumption (p = 0.005) than students with low CES-D score. According to the mediation analysis, the effect of depression symptoms on the frequency of sweet foods consumption was partially mediated by EE (23.11 % of the total effect). Conclusion: the prevalence of depression symptoms was high. EE is an important mediator in the relationship between depression symptoms and the consumption of sweet foods. Understanding the manifestation of eating behaviors in men and their relationship with depression symptoms may help clinicians and health authorities develop treatment and prevention programs aimed to decrease the risk of obesity and eating disorders.(AU)

Relationships between dental fluorosis and fluoride concentrations in bottled water and groundwater in low-income children in Mexico.

Introduction: The aim of the current study was to investigate associations between dental fluorosis in children living in low socioeconomic areas in Mexico, and fluoride concentrations in tap water, fluoride concentrations and in bottled water, and body mass index (BMI). Methods: A cross-sectional study involving 585 schoolchildren aged 8-12 years was conducted in communities in a southern state of Mexico with >0.7 parts per million (ppm) fluoride in the groundwater. The Thylstrup and Fejerskov index (TFI) was used to evaluate dental fluorosis, and the World Health Organization growth standards were used to calculate age-adjusted and sex-adjusted BMI Z-scores. A BMI Z-score ≤ -1 SD was used as the cut-off point for thinness, and multiple logistic regression models for dental fluorosis (TFI ≥ 4) were constructed. Results: The mean fluoride concentration in tap water was 1.39 ppm (SD 0.66), and the mean fluoride concentration in bottled water was 0.32 ppm (SD 0.23). Eighty-four children (14.39%) had a BMI Z-score ≤ -1 SD. More than half (56.1%) of the children presented with dental fluorosis in TFI categories ≥ 4. Children living in areas with higher fluoride concentrations in the tap water [odds ratio (OR) 1.57, p = 0.002] and bottled water (OR 3.03, p < .001) were more likely to have dental fluorosis in the severe categories (TFI ≥ 4). BMI Z-score was associated with the probability of dental fluorosis (TFI ≥ 4; OR 2.11, p < 0.001), and the effect size was 29.3%. Discussion: A low BMI Z-score was associated with a higher prevalence of dental fluorosis in the severe category. Awareness of the fluoride concentrations in bottled water may help prevent dental fluorosis, particularly in children exposed to several high fluoride content sources. Children with a low BMI may be more vulnerable to dental fluorosis.

Comparison of body fat percentage assessments by bioelectrical impedance analysis, anthropometrical prediction equations, and dual-energy X-ray absorptiometry in older women.

Background: Individuals with high body fat have a higher risk of mortality. Numerous anthropometric-based predictive equations are available for body composition assessments; furthermore, bioelectrical impedance analysis (BIA) estimates are available. However, in older adults, the validity of body fat estimates requires further investigation. Objective: To assess the agreement between percentage body fat (BF%) estimates by BIA and five predictive equations based on anthropometric characteristics using dual X-ray absorptiometry (DXA) as reference method. A secondary objective was to identify whether excluding short-stature women improves the agreement of BF% estimates in a group of community-dwelling, older Mexican women. Methods: A concordance analysis of BF% was performed. A total of 121 older women participated in the study. Anthropometric information, BIA, and DXA body composition estimates were obtained. Five equations using anthropometric data were evaluated in order to determine body fat percentage (BF%) using DXA as reference method. Paired t-test comparisons and standard error of estimates (SEE) were obtained. The Bland-Altman plot with 95% limits of agreement and the concordance correlation coefficient (CCC) were used to evaluate the BF% prediction equations and BIA estimates. Results: The mean age of the study participants was 73.7 (±5.8) years old. BIA and the anthropometric based equations examined showed mean significant differences when tested in the entire sample. For the taller women (height > 145 cm), no significant difference in the paired comparison was found between DXA and BIA of BF% estimates. The mean BF% was 40.3 (±4.8) and 40.7 (±6.2) for DXA and BIA, respectively. The concordance between methods was good (CCC 0.814), (SEE 2.62). Also, in the taller women subset, the Woolcott equation using waist-to-height ratio presented no significant difference in the paired comparison; however, the error of the estimates was high (SEE 3.37) and the concordance was moderate (CCC 0.693). Conclusion: This study found that BIA yielded good results in the estimation of BF% among women with heights over 145 cm. Also, in this group, the Woolcott predictive equation based on waist circumference and height ratio showed no significant differences compared to DXA in the paired comparison; however, the large error of estimates observed may limit its application. In older women, short stature may impact the validity of the body fat percentage estimates of anthropometric-based predictive equations.

Diagnosis of Dental Fluorosis Using Micro-Raman Spectroscopy Applying a Principal Component-Linear Discriminant Analysis.

Dental fluorosis is an irreversible condition caused by excessive fluoride consumption during tooth formation and is considered a public health problem in several world regions. The objective of this study was to evaluate the capability of micro-Raman spectroscopy to classify teeth of different fluorosis severities, applying principal component analysis and linear discriminant analysis (PCA-LDA), and estimate the model cross-validation accuracy. Forty teeth of different fluorosis severities and a control group were analyzed. Ten spectra were captured from each tooth and a total of 400 micro-Raman spectra were acquired in the wavenumber range of 250 to 1200 cm-1, including the bands corresponding to stretching and bending internal vibrational modes ν1, ν2, ν3, and ν4 (PO43-). From the analysis of the micro-Raman spectra an increase in B-type carbonate ion substitution into the phosphate site of the hydroxyapatite as fluorosis severity increases was identified. The PCA-LDA model showed a sensitivity and specificity higher than 94% and 93% for the different fluorosis severity groups, respectively. The cross-validation accuracy was higher than 90%. Micro-Raman spectroscopy combined with PCA-LDA provides an adequate tool for the diagnosis of fluorosis severity. This is a non-invasive and non-destructive technique with promising applications in clinical and epidemiological fields.

Effect of Income Level and Perception of Susceptibility and Severity of COVID-19 on Stay-at-Home Preventive Behavior in a Group of Older Adults in Mexico City.

Early information on public health behaviors adopted to prevent the spread of coronavirus (COVID-19) may be useful in controlling the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmission. The objective of this study was to assess the role of income level (IL) and the perception of older adults, regarding COVID-19 susceptibility and severity, on adopting stay-at-home preventive behavior during the first week of the outbreak in Mexico. Participants in this cross-sectional study were urban community dwellers, aged ≥ 65 years from Mexico City. A total of 380 interviews were conducted over the phone. The mean respondent age was 72.9 years, and 76.1% were women. Over half (54.2%) of the participants perceived their susceptibility to COVID-19 as very low or low. Similarly, 33.4% perceived COVID-19 severity as being very low or low, and 57.6% had decided to stay at home: this behavior was associated with IL (ß = 1.05, p < 0.001), and its total effect was partially mediated (15.1%) by perceived severity. Educational attainment was also associated with staying at home (ß = 0.10, p = 0.018) and its total effect was partially mediated (15.0%) by perceived susceptibility. Interventions aimed at low income and less educated older adults should be developed to improve preventive behaviors in this vulnerable group during the COVID-19 pandemic.

Prevalence of Malnutrition and Depression in Older Adults Living in Nursing Homes in Mexico City.

This study evaluated the association between nutritional status, depressive symptoms, and the number of prescription drugs taken by older adults living in nursing homes in Mexico City. In a cross-sectional study, 262 participants were subjected to anthropometric and nutritional (Mini Nutritional Assessment (MNA)) evaluations; additionally, their depression (Geriatric Depression Scale (GDS)) and functional status were assessed. Multiple logistic regression was used for identifying factors associated with the risk of malnutrition/malnourishment. The mean age of participants was 83.1 ± 8.6 years. A total of 59.9% and 21.1% were at risk of malnutrition and malnourished, respectively. With respect to depression, 27.9% of the participants had mild depression, while 11.4% showed severe depression. An inverse correlation between MNA evaluations and depression scores was found (Spearman's ρ = -0.4624, p < 0.001); residents with a better nutritional status had lower depression scores. Individuals with depressive symptoms were approximately five times more likely to be at risk of malnutrition or malnourished (OR = 5.82, 95% CI = 2.27-14.89) than individuals without depression. Residents taking three or more prescription drugs daily (OR = 1.83, 95% CI = 1.27-2.63, p < 0.001) were more likely to be at risk of malnutrition or malnourished. In summary, poor nutritional status was associated with depression, while the intake of numerous prescription drugs was associated with being at risk of malnutrition or malnourished.

Prevalence and Severity of Molar-Incisor Hypomineralization, Maternal Education, and Dental Caries: A Cross-Sectional Study of Mexican Schoolchildren with Low Socioeconomic Status.

OBJECTIVES: The aims of this study were to identify the prevalence of molar-incisor hypomineralization (MIH) in a group of low-income schoolchildren and to evaluate the role of maternal education on MIH and dental caries in these children. MATERIALS AND METHODS: This cross-sectional study enrolled 686 schoolchildren. To evaluate dental caries, the International Caries Dental Assessment System II (ICDAS) criteria were utilized. MIH was assessed by using the European Academy of Paediatric Dentistry criteria. Mixed-effects models were applied for the data analysis. RESULTS: The prevalence of MIH was 35.4% (244). Most children exhibited moderate MIH (163, 67.1%), followed by mild MIH (45, 18.5%) and severe MIH (35, 14.4%). Caries presence in the first permanent molars, evaluated using ICDAS score, indicated that the mean number of noncavitated and cavitated lesions (ICDAS ≥2) was 0.90 (±0.30); the mean number of lesions with ICDAS ≥3 was 0.36 (±0.48). Odds ratio (OR) analysis of MIH severity revealed that the children of mothers with low education were more likely to exhibit MIH (OR 2.13; 95% confidence interval [CI]: 1.25-3.85). Modeling of dental caries (ICDAS ≥3) revealed that low maternal education (OR 2.27; 95% CI: 1.25-4.16) and the presence of MIH (OR 4.37; 95% CI: 3.05-6.25) were associated with dental caries. CONCLUSIONS: There were associations between low maternal education and both MIH and dental caries. The presence of both initial and cavitated caries lesions was associated with MIH. Dentists should offer adequate advice to mothers with children with MIH, based on their educational background.

Impact of caries and dental fluorosis on oral health-related quality of life: a cross-sectional study in schoolchildren receiving water naturally fluoridated at above-optimal levels.

PURPOSE: The purpose of this study was to evaluate the impact of caries and fluorosis on oral health-related quality of life (OHRQoL) among schoolchildren living in areas with high concentrations of fluoride in water. METHODS: Five hundred and twenty-four schoolchildren (8-12 year olds) residing in rural communities in central Mexico were examined for oral hygiene, caries (International Caries Detection and Assessment System, ICDAS II), and fluorosis (Thylstrup and Fejerskov Index, TFI). OHRQoL was evaluated with the Child Perceptions Questionnaire for two age groups (CPQ8-10 and CPQ11-14). Generalized structural equation models were constructed for data analysis. RESULTS: Overall prevalence of caries was 88.5% and fluorosis 46.9%. In the group of 8-10 year olds, 48% of the children had advanced carious lesions in primary or permanent teeth (ICDAS ≥4), 22.6% had moderate/severe fluorosis, and 59.9% of children had an impact on OHRQoL. Schoolchildren with ICDAS ≥4 were more likely [OR = 1.75, (95% CI 1.34-2.28)] to suffer a negative impact on OHRQoL. In the group of 11-12 year olds, 19.9% of children had advanced carious lesions and 23.2% showed moderate/severe fluorosis; 67.3% of children reported had an impact on OHRQoL. Children 11-12 year olds with fluorosis (TFI ≥4) [OR = 2.39 (95% CI 2.12-2.69)], caries (ICDAS ≥4) [OR = 2.18 (95% CI 2.13-2.24)], and low brushing frequency [OR = 2.04 (95% CI 1.21-3.44)] were more likely to have deterioration on OHRQoL. CONCLUSION: A negative impact on OHRQoL was observed in children with caries and fluorosis. CLINICAL RELEVANCE: Deterioration on OHRQoL found in children as a sequel of caries and fluorosis should be considered when designing health policies leading to prevention and effective health promotion programs and incorporated to clinical guidelines for timely dental treatment.

Relationship between severe early childhood caries, mother's oral health and mutans streptococci in a low-income group: changes from 1996 to 2007.

UNLABELLED: The relationship between dental caries and mutans streptococci (ms) in children and their mothers is a key factor in the prevention of early childhood caries. Changes in early childhood caries over time in Mexican children have not been well documented. OBJECTIVE: To compare the dental caries indices and presence of ms in 3- to 5-year-old children and their mothers in two surveys, the first one carried out in 1996 and the second one in 2007. STUDY DESIGN: Cross-sectional study. RESULTS: The first survey included 102 mother-child dyads and the second 103. Dental caries index dmfs was 7.17 (+/- 10.9) and 4.58 (+/- 7.1) in the first and second survey, respectively (p < 0.05). Ms levels were higher in 1996 than in 2007 (p < 0.001). The prevalence of Severe Early Childhood Caries (SECC) was 42.2% and 34.95% in first and second surveys, respectively, (p > 0.05). Children with SECC showed higher counts of ms than children without this condition. A high caries index in mothers was associated with higher caries experience in their children. CONCLUSION: The compassions of the surveys indicated a decline in dental caries indices over an 11-year period. High caries experience in the mother had a negative impact on the oral condition of the child.

Oral and pharyngeal cancer mortality rates in Mexico, 1979-2003.

BACKGROUND: In Mexico, information on oral and pharyngeal cancer (OPC) is scarce. The purpose of this study was to explore the trends in OPC mortality rates in Mexico from 1979 through 2003 and to describe the distribution of OPC deaths for selected socio-demographic variables for the period of 2001-2003. MATERIAL AND METHODS: Annual crude and age-adjusted mortality rates were obtained by gender and site of lesion, using the 2003 WHO World standard million population. The Poisson regression model was used to detect a trend in the mortality rates, testing the hypothesis beta(1) = 0. Also, the annual percentage change (APC) was computed over the age-adjusted rates. RESULTS: The total number of OPC deaths during the period 1979-2003 was 15,576. The age-adjusted mortality rate was 1.13/100,000 in 1979 and 1.08/100,000 in 2003. Oral cancer was more frequently found than salivary gland and pharyngeal cancer (41.5% vs. 13.4% and 17.1%). The tongue (19%) was the most frequent oral affected site. The Poisson regression analysis indicated a stationary trend in cancer mortality rate; also, the APC regression model showed no increase or decrease in OPC from 1979 to 2003. CONCLUSIONS: Oral and pharyngeal cancer mortality rates in Mexico were low compared to most countries, and remained stable in the past two decades.

Attitudes of a group of Mexico City residents toward HIV/AIDS in the dental office.

OBJECTIVE: To ascertain the intention of the public to undergo dental treatment at dental clinics where other patients or a dentist are infected with HIV/AIDS. STUDY DESIGN: A cross-sectional design was used to interview a stratified sample of persons 18 years and older in Mexico City with use of a standardized questionnaire. Questions included the type of dental service used, the perception of risk for HIV/AIDS contagion in the dental environment, and the reported intention to continue treatment in a dental office where patients or a dentist were affected by HIV/AIDS. RESULTS: Of the 490 participants, 74.9% were concerned about HIV/AIDS transmission in the dental office. Only 21.2% intended to continue treatment at a dental office where HIV/AIDS patients were treated, and only 20.0% intended to continue treatment when the dentist was HIV-positive. The degree of concern about HIV/AIDS contagion and the modality of dental service used were associated with the stated intention to continue dental treatment. CONCLUSIONS: There is a need to have good infection control standards in dental practice; to increase public trust in such standards by making them more apparent; and/or to establish educational programs to improve public knowledge and attitudes toward HIV/AIDS risks in dental practice.

Estimar valores antropométricos en un grupo de hombres y mujeres de la tercera edad en la Ciudad de México. Material y métodos. Se realizó un estudio de corte transversal en 508 sujetos mayores de 60 años, registrados como jubilados y pensionados del Instituto Mexicano del Seguro Social o asistentes al Instituto Nacional de la Senectud, durante el segundo semestre de 1995. Se utilizaron protocolos de estandarización para registrar sus caractarísticas antropométricas. Se realizaron pruebas t de Student para detectar diferencias en los valores promedio entre hombres y mujeres, en general, como en cada subgrupo de edad conformado; también el análisis de correlación de Pearson del índice de masa corporal (IMC) con las variables antropométricas; se tomó un nivel de significancia de p<0.05. Resultados. Doscientos treinta individuos de la población de estudio correspondieron al sexo masculino y 278 al femenino, la edad promedio fue de 66.9 y 67.3 años, respectivamente. El promedio de peso en los hombres fue de 70.7 kg, con una desviación estándar (DE) de 9.9, la estatura de 164 cm (DE 6.5) y el IMC de 26.4 (DE 3.7). La distribución del IMC mostró que 50.9 por ciento de los hombres y 54 por ciento de las mujeres evaluados se ubicaron en el rango de 25.0 a 29.9; se obtuvo un coeficiente de correlación superior a r 0.70 (p<0.001) entre el IMC con las circunferencias de cintura y cadera. Conclusiones. Con base en el IMC, aproximadamente tres cuartas partes de la población de estudio presentó sobrepeso u obesidad. Es posible que la evaluación tanto de sobrepeso como de obesidad en el anciano requiera de un ajuste en los valores de normalidad de este índice

The aim of the present study was to estimate basic anthropometric measurements in a group of elderly men and women from Mexico City. Material and methods. A cross-sectional study was carried out among senior citizens registered in the National Institute of the Elderly and National Institute of Social security in Mexico City. Standardized protocols were used to measure the anthropometric characteristics of the study group. The analysis included Student t tests to detect differences in average values between men and women in general and in each age subgroup formed. In addition, Pearson correlation analysis of the body mass index (BMI) with anthropometric variables was performed; p<0.05 was taken as the level of significance. Results. A total of 508 people aged 60 or older participated in the study; 230 were males and 278 were females. The average age was 66.9-years-old in the male group and 67.3-years-old in the female group. Among men the average weight was 70.7 kg, standard deviation (SD 9.9), height was 164 cm (SD 6.5) and BMI was 26.4 (SD 3.7). Among women the average weight was 60.8 kg (SD 9.9), height was 150 cm (SD 5.9) and BMI was 27.1 (SD 4.0). The distribution of the BMI showed that 50.9% of men and 54% of women were between 25.0 and 29.9. A correlation coefficient over r 0.70 (
