Treatment options for mandibular canine transmigration - a case series based on dental literature.

The present case series, based on dental literature, aimed to identify factors that influence the final treatment decision for patients affected by mandibular canine transmigration using individual data from case reports in the literature. The protocol used for data synthesis was prepared following the Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines. An online search was conducted and included studies published up until September of 2019 (MEDLINE, Google Scholar, Scielo, and Conricyt). A chi squared test was used to evaluate associations between the treatment choice and gender, age, Mupparapu classification, and the presence of oral pathologies or dental anomalies (p < 0.05). A multinomial logistic regression was used to evaluate the individual case report data to determine the effect of the explanatory variables for treatment selection. Seventy-six papers fulfilled the inclusion criteria. Surgical removal (46.71%) and radiographic monitoring (38.16%) were the most common treatments reported. Age, Muppararu classification, and the presence of oral pathologies were significantly associated with the treatment option (p < 0.05). In conclusion, surgical removal and radiographic monitoring are the most frequently reported treatments for mandibular canine transmigration. Age, Mupparapu type, presence of oral pathologies, and qualitative aspects such as emotional reasons are relevant for the decision regarding treatment approach.

Sociodemographic, Socio-economic, Clinical and Behavioural Factors Modifying Experience and Prevalence of Dental Caries in the Permanent Dentition.

OBJECTIVE: To identify the sociodemographic, socio-economic, clinical and behavioural factors that modify the experience of decayed, missing and filled teeth (DMFT) and caries prevalence in Nicaraguan children 9-12 years old. SUBJECTS AND METHODS: We conducted a cross-sectional study in 800 school children 9-12 years old in the city of León, Nicaragua. The clinical oral examinations to identify caries experience were undertaken by two trained and certified examiners. Sociodemographic, socio-economic and behavioural data were collected using questionnaires. Negative binomial regression (NBR) and binary logistic regression (BLR) models were used to model caries experience and caries prevalence, respectively. RESULTS: Mean DMFT index was 0.98 ± 1.74 and caries prevalence (DMFT > 0) was 37.9%. In the NBR model, the categories that increase the expected DMFT mean were: older age, female gender, presence of plaque, and if the school children received curative and curative/preventive dental care in the last year. In the BLR model, the odds of presenting with caries in the permanent dentition were increased in older children, those from large families, mothers with a positive dental attitude, and those school children who received curative and curative/preventive dental care in the last year. CONCLUSIONS: Using different models, we identified several sociodemographic, socio-economic, clinical and behavioural factors that modify the experience (NBR) and prevalence (BLR) of dental caries.

Salivary Parameters (Salivary Flow, pH and Buffering Capacity) in Stimulated Saliva of Mexican Elders 60 Years Old and Older.

OBJECTIVE: To compare a limited array of chewing-stimulated saliva features (salivary flow, pH and buffer capacity) in a sample of elderly Mexicans with clinical, sociodemographic and socio-economic variables. SUBJECTS AND METHODS: A cross-sectional study was carried out in 139 adults, 60 years old and older, from two retirement homes and a senior day care centre in the city of Pachuca, Mexico. Sociodemographic, socio-economic and behavioural variables were collected through a questionnaire. A trained and standardized examiner obtained the oral clinical variables. Chewing-stimulated saliva (paraffin method) was collected and the salivary flow rate, pH and buffer capacity were measured. The analysis was performed using non-parametric tests in Stata 9.0. RESULTS: Mean age was 79.1 ± 9.8 years. Most of the subjects included were women (69.1%). Mean chewing-stimulated salivary flow was 0.75 ± 0.80 mL/minute, and the pH and buffer capacity were 7.88 ± 0.83 and 4.20 ± 1.24, respectively. Mean chewing-stimulated salivary flow varied (p < 0.05) across type of retirement home, tooth brushing frequency, number of missing teeth and use of dental prostheses. pH varied across the type of retirement home (p < 0.05) and marginally by age (p = 0.087); buffer capacity (p < 0.05) varied across type of retirement home, tobacco consumption and the number of missing teeth. CONCLUSIONS: These exploratory data add to the body of knowledge with regard to chewing-stimulated salivary features (salivary flow rate, pH and buffer capacity) and outline the variability of those features across selected sociodemographic, socio-economic and behavioural variables in a group of Mexican elders.

Estudio ecológico en México (2003-2009) sobre labio y/o paladar hendido y factores sociodemográficos, socioeconómicos y de contaminación asociados / Ecologic study in Mexico (2003-2009) on cleft lip and/or palate and associated sociodemographic, socioeconomic and pollution factors

Objetivo: Analizar de 2003 a 2009 las tasas de labio y/o paladar hendido (LPH) en México y determinar su asociación a nivel ecológico con variables sociodemográficas, socioeconómicas y de contaminación. Material y métodos: Se realizó un estudio ecológico utilizando datos de la incidencia de LPH. También se incluyó información en cuanto a aspectos sociodemográficos, socioeconómicos y de contaminación, obtenida de instituciones públicas gubernamentales. Se utilizó como variable dependiente la tasa de incidencia del LPH, y como variables independientes los indicadores socioeconómicos, sociodemográficos y de contaminación. En el análisis se utilizaron las pruebas de correlación de Spearman y de la chi cuadrado. Resultados: Durante el período estudiado se presentaron 10.573 nuevos casos de LPH (promedio de 1.510,43 por año). Los estados con mayor tasa de LPH (x 1.000 nacidos) fueron: en 2003 Distrito Federal (1,76), en 2004 Jalisco (2,62), en 2005 Oaxaca (1,66), en 2006 Estado de México (1,29), en 2007, 2008 y 2009 Jalisco (2,17, 2,92 y 1,99, respectivamente). Los varones fueron los más afectados (p < 0,05). Las variables correlacionadas positivamente a las tasas de LPH fueron: población total, residuos sólidos, esperanza de vida, sólidos urbanos; y negativamente: porcentaje de consumidores altos de alcohol y abuso o dependencia de alcohol. Conclusiones: Jalisco fue el estado más afectado cada año. Se encontraron correlaciones ecológicas entre las tasas de LPH con factores sociodemográficos, socioeconómicos y de contaminación, aunque de forma inversa con el consumo de alcohol. Es necesario realizar estudios epidemiológicos más detallados sobre el tema para caracterizar adecuadamente los factores de riesgo en poblaciones mexicanas (AU)

Objective: To analyze the rates of cleft lip and/or cleft palate (CLP) in Mexico between 2003and 2009 and assess their association with variables at ecological level, sociodemographic, socioeconomic, and pollution. Material and methods: An ecological study was conducted with data from the 32 states of Mexico for incidence of CLP, obtained from the Ministry of Health. We included sociodemographic, socioeconomic, and pollution information, obtained from governmental agencies. CLP incidence rates were used as dependent variable; independent variables were socioeconomic, demographic and pollution indicators. Statistical analysis was performed using Spearman correlation and chi2 tests .Results: During the study period 10573 new cases presented (mean 1510.43 per year). The States with the highest rate (per 1000 births) were: in 2003 the Federal District (Mexico City)(1.76), in 2004 Jalisco (2.62), in 2005 Oaxaca (1.66), in 2006 the State of Mexico (1.29), in 2007, 2008 and 2009 Jalisco (2.17, 2.92, and 1.99). For all the years men were more likely affected than women (P < 0.05). Variables found positively correlated to LPH rates were total population, solid waste, life expectancy, urban solid waste. The variables negatively correlated were population percentages of high alcohol users, and of alcohol abuse or addiction. Conclusions: The State of Jalisco was one of the most affected locations over the years. Ecologic positive correlations existed between cleft lip and/or palate and sociodemographic, socioeconomic, and pollution factors. Incidence rate was negatively correlated with alcohol use and abuse. More detailed epidemiological studies are needed to fully characterize risk factors in Mexican populations (AU)
