RESUMO
OBJECTIVE: To describe trends in cases and prevalence at birth rates of cleft lip and/or palate (CL/P) in Mexico between 2003 and 2019. DESIGN: Ecological study. SETTING: Multiple data sources systematically collected into a national epidemiological surveillance data warehouse. PARTICIPANTS: National Live Birth Information System. MAIN OUTCOME MEASURE(S): Both cases and prevalence at birth rates of CL/P in Mexico within a 17-year period were used as dependent variables. RESULTS: At the national level there were 23â 184 new cases of CL/P (average of 1364 per year) in the 32 states of Mexico, with an average prevalence at birth rate of 0.53 per 1000 live births. The states with the highest prevalence at birth rates of CL/P during the period were Hidalgo (1.59) and Jalisco (1.32), while the states with the lowest rates were Nayarit (0.22) and Durango (0.29). A slight decrease in both cases (z = -2.41, P = .016) and prevalence at birth rates (z = -2.58, P = .010) of CL/P was observed at the national level. States such as Durango, Puebla, Chiapas, Guerrero, Oaxaca, Mexico City, State of Mexico, Coahuila and Jalisco showed a clear downward trend (P < .05) in their prevalence at birth of CL/P between 2003 and 2019, while in Hidalgo its trend was upward (P = .05). Significant differences by sex and region were observed (P < .05). CONCLUSION: Some states consistently had the highest or lowest prevalence of CL/P. Decreasing trends in the overall prevalence at birth rates were observed. More detailed, epidemiological studies are necessary to adequately characterize CL/P in the Mexican population.

OBJECTIVE: This study was conducted to determine the experience of tooth loss, as well as its associated variables, in a sample of adult Mexicans, aged 60 years and older. MATERIALS AND METHODS: This cross-sectional study was part of a larger project to measure diverse oral health indicators in a convenience sample: it included 139 adult Mexican seniors (69.1% of whom were women), ages 60 years and older, either living in long-term care facilities or living independently and participating in adult day care services. Each participant underwent an oral examination to determine the number of missing teeth. Questionnaires were administered to collect sociodemographic, socioeconomic, and behavioral data. Statistical analyses were performed using nonparametric tests and negative binomial regression. RESULTS: The mean age was 79.06 (±9.78 years). The mean number of missing teeth was 20.02 (±8.61; median, 24); 99.3% of the participants had at least 1 missing tooth, and only 14 had 20 teeth or more. Using a negative binomial regression multivariate model, we found that for each year's increase in age, the mean number of teeth lost increased by 1% (p<0.05). In individuals who brushed their teeth fewer than two times a day, who had received radiotherapy, or who were currently smokers, the average tooth loss increased 49.2%, 22.6%, and 19.0%, respectively (p<0.01). CONCLUSION: Tooth-loss experience in these Mexican seniors was very high (20.02±8.61). Older age (within the range of this group of seniors), tooth-brushing patterns, the receipt of radiation therapy, and (current) tobacco use were associated with higher experience of tooth loss.

The objective of this study was to quantify the prevalence of and identify the factors associated with dental pain among elementary- and middle-school students in Mexico. An ecological study was carried out with data from the 2008 National School-based Student-Health Survey. Information on dental pain from schoolchildren (aged 5 to 16 years) was collected from public schools across the 32 states of Mexico. In the original study, a questionnaire was used to explore various factors that affect the oral and dental health status of schoolchildren. The outcome variable was the prevalence rate (for dental pain) reported at state level. Various contextual socioeconomic variables were included, in addition to dental caries. Analyses were performed using Stata software. 52.9% of interviewees were girls; 26.9% of male and female schoolchildren in Mexico experienced gum or dental pain during the period analyzed (95% Confidence Interval = 26.02, 27.77%); according to the Spearman correlation results, self-reported dental pain was unrelated (p > 0.05) to the socioeconomic and sociodemographic variables that make up the Gross Domestic Product (GDP) and the Human Development (HDI), as well as the marginalization and the Gini indices. However, the estimated percentages of self-reported dental pain and caries were positively correlated in the elementary- (r = 0.8958, p < 0.0001), middle-school (r = 0.8958, p < 0.0001) and total populations (r = 0.8542, p < 0.0001). Prevalence of self-reported dental pain was 28%, or about one in three, of the Mexican children and adolescents in the study sample. The state-level sociodemographic and socioeconomic risk indicators were not associated with the prevalence of dental pain. Self-reported caries was positively correlated with self-reported dental pain.

The aim of this study was to determine the prevalence of dental trauma in schoolchildren 6 to 12 years of age and associated clinical, sociodemographic, and socioeconomic variables. A cross-sectional study was conducted in 477 children from public elementary schools in four locations in Mexico. The dependent variable was dental trauma, which was dichotomized in 0 = without dental trauma and 1 = with dental trauma. For the statistical analysis, a multivariate binary logistic regression model was generated in Stata. Average age was 9.06±1.94 years and 51.1% were girls. The prevalence of dental trauma was 18.2%. Falls, automobile accidents and sports had the highest number of instances (p < 0.01). In the multivariate model, it was observed that the risk of dental trauma increased with age (OR = 1.28) and among boys (OR = 1.45). Schoolchildren with decreased overjet (OR = 0.38) had lower dental trauma. Father's age (OR = 1.03) and educational level (OR = 1.78) were associated with dental trauma. Schoolchildren without health insurance (OR = 0.62) presented dental trauma less often. This study provided important information regarding the association of different sociodemographic, socioeconomic and clinical variables with dental trauma in Mexican schoolchildren. Identifying factors associated with dental trauma may support health promotion opportunities to ameliorate the prevalence of dental trauma.

The objective of the present study was to characterize socioeconomic inequalities in the patterns of professionally applied topical fluoride (PATF) in Mexican schoolchildren. A cross-sectional study was carried out on 3029 Mexican schoolchildren. A questionnaire was administered to caregivers to determine sociodemographic, socioeconomic, and behavioral variables. The dependent variable was prevalence of PATF, coded as 0 = without PATF and 1 = with PATF, at any point in life, and separately, in the previous year. Various indicators of socioeconomic position were included. Logistic regression was used in the final multivariate analysis. The prevalence of PATF any time in life was 33.8%, while in the previous year it was 11.4%. The variables associated (p < 0.05) with PATF any time in life were child's older age (OR = 1.12), older age when tooth brushing started (OR = 1.57), higher brushing frequency (OR = 1.60), having health insurance [public (OR = 1.61) or private (OR = 1.45)], if family owned a car (OR = 1.29) and better socioeconomic position [parents' education, second (OR = 1.48) and third (OR = 1.75) tertile]. For PATF in the previous year, the variables associated were older age of mother (OR = 1.03), older age when tooth brushing started (OR = 1.99), higher brushing frequency (OR = 1.68), having health insurance [public (OR = 1.62)] and better socioeconomic position (parents' education, second (OR = 1.57) and third (OR = 1.97) tertile). This study suggests the existence of socioeconomic inequalities in PATF, manifested through socioeconomic position, access to health insurance and household having a car. Identifying and addressing PATF inequalities would improve oral health in the child population.

The aim of this study was to identify if the prevalence of dental pain (past and / or present) is associated with caries experience in Mexican children, as well as to characterize factors associated with dental pain. A cross-sectional study was conducted in a consecutive sample of 309 children 2 to 12 years old who were patients at a dental school clinic in Toluca, Mexico. Data were collected from clinical records. The dependent variable had three categories: 0 = have never had dental pain, 1 = had dental pain before the appointment, and 2 = current dental pain. Non-parametric statistical tests were used in the analysis. A multivariate multinomial logistic regression model was generated in Stata 11.0. Average age was 5.71 ± 2.43 years and 50.8% were boys. The joint dmft+DMFT index was 9.11 ± 4.19. It was observed that 56.6% of children did not report having experienced dental pain, 30.7% reported having previously had dental pain, and 12.6% had pain when the clinical appointment took place. In the multivariate model, variables associated (p < .05) with previous dental pain were age (OR = 1.13); the dmft + DMFT index (OR = 1.13), having had a last dental visit for curative/emergency reasons (OR = 2.41) and prior experience of dental trauma (OR = 2.59). For current pain, only the joint dmft + DMFT index (OR = 1.10, p < 0.05) had significant associations. Almost half of the children had experienced dental pain in their lifetime. Since caries experience is a factor associated with dental pain, decreasing caries levels may ameliorate suffering from dental pain in children.

OBJECTIVE: To identify the prevalence of and factors associated with the use of dental health services to receive professionally applied topical fluoride (DHSU-PATF) in the 12 months prior to the study among Mexican schoolchildren aged 6 to 12 years. METHODS: A cross-sectional study was performed in 1,404 schoolchildren selected randomly from 15 public schools in the city of Pachuca, Mexico. Questionnaires were distributed to determine the demographic, socioeconomic, and behavioral variables. The dependent variable was the DHSU-PATF in the year before the study, which was dichotomized as 0 (no DHSU-PATF) or 1 (yes, DHSU-PATF). We calculated odds ratios (OR) and 95% confidence intervals. The analysis was performed in Stata 11.0. RESULTS: The prevalence of DHSU-PATF was 5.1%, but lower among younger children (OR = 0.86) and greater among children with health insurance (private insurance, OR = 3.64; insurance provided by the government owned oil company, the Army, or the Navy, OR = 5.03). The level of knowledge about oral health among guardians/ parents was also a factor (medium, OR = 2.37; high, OR = 4.05). Additionally, among the children whose parents/guardians perceived them (the children) as having good or very good oral health, the OR was 3.33; among children whose parents brushed their teeth with greater relative frequency, the OR was 8.74. Finally, DHSU-PATF was greater among children with relatively higher socioeconomic status (2nd quartile, OR = 3.29; 3rd quartile, OR = 5.99; 4th quartile, OR = 4.64). CONCLUSION: The receipt of PATF was low in this sample of Mexican schoolchildren and is associated with socioeconomic and behavioral factors. This gives us a guideline to create or improve topical fluoride application strategies in the public and private Mexican health systems.

To analyze whether a correlation exists between the caries status (Decayed, Missing and Filled Teeth, DMFT Index) of the first permanent molars (FPMs) and that of the full permanent dentition of Mexican adolescents, and to propose its use in large epidemiological studies of dental caries.We conducted a cross-sectional study of 1538 adolescents from 12 to 15 years old. Based on a clinical oral examination, we determined the DMFT Indices of their FPMs (FPM-DMFT) and of their full permanent dentition (comprehensive DMFT Index). We explored each FPM to determine whether it was with or without caries, filled, missing or sealed. For our statistical analysis, we used Fisher exact test and Spearman correlation in Stata software.After examining a total of 6157 FPMs, we found that 56.8% of our sample of adolescents had no caries in their 4 FPMs whereas 4.9% experienced caries in all 4. No significant differences emerged by sex (Pâ>â.05); however, by age, the older adolescents experienced greater FPM-DMFT (Pâ<â.05). Analysis yielded a correlation of râ=â0.8693 between the FPM-DMFT and comprehensive DMFT scores (Pâ<â.0001) of participants. The underestimation of caries prevalence (DMFTâ>â0) was 5.4% (48.6% vs 43.2%), while the DMFT Index was underestimated at 0.34 (1.15 vs 0.81).The strong correlation between the FPM-DMFT and comprehensive DMFT Indices suggests that overall caries status can be inferred on the basis of FPM caries status. This evidence is useful when conducting large epidemiological studies such as national surveys.

OBJECTIVE: To identify the association between tooth brushing frequency and variables of socioeconomic position in Nicaraguan schoolchildren. MATERIAL AND METHODS: A cross sectional study was undertaken in 1353 schoolchildren ages 6 to 12 randomly selected from 25 elementary schools in Leon, Nicaragua. Using a questionnaire addressed to mothers, sociodemographic, socioeconomic and behavioral variables were collected. The dependent variable was tooth brushing frequency, which was dichotomized in 0 "at least one 7 times/week" and 1 "7 or more times/week". A multivariate analysis was carried out with logistic regression in STATA 9. RESULTS: The average age of child participants was 8.99 +/- 2.00 years and 49.7% were women. In the final model, older age (OR = 2.04), female sex (OR = 1.39) and having a mother with positive attitudes toward oral health (OR = 2.5) were positively associated with the tooth brushing frequency (p < 0.05). Larger family size (OR = 0.89) and having low socioeconomic status (1st quartile; OR = 0.54, 2nd quartile; OR = 0.62, 3rd quartile; OR = 0.67) showed a negative relationship with the tooth brushing frequency. To have had at least one preventive dental visit in the previous year was positively associated (p < 0.10) with tooth brushing frequency. CONCLUSION: This study suggested that existence of indicators of socioeconomic inequalities exist even within less developed countries, and thus emphasize the need to target health promotion programs to vulnerable socioeconomic groups.

Dental caries-a highly prevalent public health problem in preschoolers and school children-is the main cause of premature dental loss during childhood, and this may be related to loss of space in the posterior sector. The objective of this study was to evaluate whether interproximal caries and premature tooth loss (D and/or E) are risk factors for loss of space in the posterior sector.A comparative cross-sectional study (split-mouth type) was performed in schoolchildren (6-8 years old). Seventeen gypsum models were evaluated. These children presented with unilateral loss of a dental organ or interproximal caries (teeth D and/or E) and without such affectations on the other side. Measurements were made with a digital Vernier caliper. The dependent variable was the difference (loss of space, mm) between the control and case sides. The independent variables were type of affectation (interproximal caries or tooth loss), sex, age, arcade, and number of interproximal surfaces affected.The mean age was 6.82â±â0.44 years and 64.7% were boys. The average space loss was 1.09â±â0.18âmm (control vs case; Pâ<â.0001). A greater loss of space was observed among those who lost a dental organ than those with interproximal caries (Pâ=â.0119). A correlation was observed between the variable loss of space and the number of interproximal surfaces affected (râ=â0.5712, Pâ=â.0166).Interproximal caries and tooth loss were risk factors for loss of space in the posterior segment in this sample of Mexican schoolchildren.

Aim: The objective of this study was to estimate the Out-Of-Pocket Expenditures (OOPEs) incurred by households on dental care, as well as to analyze the sociodemographic, economic, and oral health factors associated with such expenditures. Method: A cross-sectional study was conducted among 763 schoolchildren in Mexico. A questionnaire was distributed to parents to determine the variables related to OOPEs on dental care. The amounts were updated in 2017 in Mexican pesos and later converted to 2017 international dollars (purchasing power parities-PPP US $). Multivariate models were created: a linear regression model (which modeled the amount of OOPEs), and a logistic regression model (which modeled the likelihood of incurring OOPEs). Results: The OOPEs on dental care for the 763 schoolchildren were PPP US $53,578, averaging a PPP of US $70.2 ± 123.7 per child. Disbursements for treatment were the principal item within the OOPEs. The factors associated with OOPEs were the child's age, number of dental visits, previous dental pain, main reason for dental visit, educational level of mother, type of health insurance, household car ownership, and socioeconomic position. Conclusions: The average cost of dental care was PPP US $70.2 ± 123.7. Our study shows that households with higher school-aged children exhibiting the highest report of dental morbidity-as well as those without insurance-face the highest OOPEs. An array of variables were associated with higher expenditures. In general, higher-income households spent more on dental care. However, the present study did not estimate unmet needs across the socioeconomic gradient, and thus, future research is needed to fully ascertain disease burden.

RESUMO
We determine the relationship between premature loss of primary teeth and oral hygiene, consumption of soft drinks, dental care and previous caries experience. This study focused on 833 Mexican schoolchildren aged 6-7. We performed an oral examination to determine caries experience and the simplified oral hygiene index. The dependent variable was the prevalence of at least one missing tooth (or indicated for extraction) of the primary dentition; this variable was coded as 0 = no loss of teeth and 1 = at least one lost primary tooth. The prevalence of at least one missing tooth was 24.7% (n = 206) (95% CI = 21.8-27.7). The variables that were associated with the prevalence of tooth loss (p < 0.05) included: the largest number of decayed teeth (OR = 1.11), the largest number of filled teeth (OR = 1.23), the worst oral hygiene (OR = 3.24), a lower frequency of brushing (OR = 1.60), an increased consumption of soda (OR = 1.89) and use of dental care (curative: OR = 2.83, preventive: OR = 1.93). This study suggests that the premature loss of teeth in the primary dentition is associated with oral hygiene, consumption of soft drinks, dental care and previous caries experience in Mexican schoolchildren. These data provide relevant information for the design of preventive dentistry programs.

Introducción: La hiperdoncia, es una anomalía de número en la que se forman dientes o estructuras parecidas a dientes en exceso con respecto a la cantidad normal, teniendo como resultado órganos dentales llamados supernumerarios. Presentación del caso: Paciente masculino de 7 años 11 meses de edad con dentición mixta y retraso en la erupción de los incisivos centrales y laterales superiores. En la radiografía panorámica se observa una zona radiopaca entre el incisivo central superior permanente (OD 21) y el incisivo lateral superior permanente (OD 22) diagnosticando un diente supernumerario. Con ayuda de una radiografía oclusal y una periapical de la zona se valoró y se determinó su extracción bajo anestesia local. Se realizó la cirugía sin complicaciones y se derivó al paciente a la clínica de ortodoncia. Conclusiones: En el presente reporte se pudo observar que llevando un buen control del caso y con la ayuda de estudios radiográficos se puede lograr un avance significativo sin dañar la integridad bucal del paciente en un futuro. Significancia clínica: El diagnóstico precoz puede mejorar con ayuda de los diversos tipos de radiografías disponibles en odontología, así se evitan complicaciones al paciente infantil.
Introduction: Hyperdontia is a number anomaly in which teeth or structures similar to teeth are formed in excess of the normal amount, resulting in supernumerary dental organs. Case presentation: a male patient 7 years 11 months of age with mixed dentition and delayed eruption of the central and upper lateral incisors presented for evaluation. The panoramic radiograph showed a radiopaque area between the permanent upper central incisor (OD 21) and the permanent upper lateral incisor (OD 22). A supernumerary tooth was diagnosed. With the help of an occlusal and a periapical radiograph of the area, the tooth was evaluated and an extraction under local anesthesia was planned. The surgery was performed without complications and the patient was referred to the orthodontic clinic. Conclusions: In the present report, we note that time intervention and with the help of radiographic studies, a significant result can be achieved without damaging the patient's future oral integrity. Early diagnosis can be improved with the help of the various types of radiographs available in dentistry, thus avoiding complications in infants.
RESUMO
Los dientes que erupcionan antes de tiempo, desde el nacimiento o posterior a éste, son denominados comúnmente dientes natales o neonatales. Se clasifican de acuerdo al grado de maduración o apariencia. La prevalencia varía de 1 en 44 a 1 en 30,000 nacimientos. Son más frecuentes los dientes natales que los neonatales. Por lo general, pertenecen a la dentición primaria, ocurren de forma bilateral y predominan entre las mujeres. Todavía de etiología desconocida, la teoría más aceptable es que el germen dental tiene una localización superficial. Clínicamente se ven como dientes primarios normales, suelen ser más pequeños, algunas veces de forma cónica. Generalmente son móviles por la falta de formación radicular y presentan alteraciones del esmalte; pueden revelar una apariencia inmadura con hipoplasia del esmalte de bordes irregulares y agudos; su coloración puede ser marrón-amarillento / opaco blanquecino. Radiográficamente hay ausencia de raíz. Histológicamente, la mayoría de los dientes natales y neonatales pueden seguir un patrón de mineralización normal, pero también presentan alteraciones tanto en el esmalte como en la dentina. Otros descubrimientos incluyen ausencia de la capa basal de Weil, vaina de Hertwig y cemento; además de un incremento en el número de vasos sanguíneos dilatados en la pulpa. El tratamiento debe ser adaptado a cada diente y cada niño. Los tratamientos disponibles son: la extracción o el mantenimiento del diente en la arcada. La complicación más común de los dientes neonatales o natales es la ulceración traumática de la parte ventral de la lengua debido a la fricción, llamada úlcera de Riga Fede. No hay reporte de broncoaspiración. El tratamiento de los dientes natales y neonatales deben valorarse con mucho cuidado; estimando su movilidad, integridad, compromiso de la alimentación y la presencia de alguna úlcera.
Teeth that erupt early are commonly referred to as natal or neonatal teeth. They can be classified according to the degree of maturity or appearance. Their prevalence varies from 1 in 44 to 1 in 30,000 births. Natal teeth are more frequent than neonatal teeth, and they often belong to the primary dentition; they occur bilaterally and principally among women. The etiology of these teeth is unknown, and the most acceptable theory is that the tooth germ is located superficially. Clinically, they resemble normal primary teeth, although they are often smaller and sometimes conical. They are generally characterized by a lack of root formation, changes in enamel and dentin, an immature appearance with hypoplastic enamel and sharp irregular and edges, and yellowish-brown/white opaque coloration. Radiographically there is no root. Histologically, most natal and neonatal teeth may follow a pattern of normal mineralization, but also have alterations in both enamel and dentin. Other findings include absence of the basal layer of Weil, Hertwig's sheath and cement; besides an increase in the number of blood vessels in dilated pulp. Treatment should be tailored to each tooth and each child. Available treatments include extraction or maintenance of the tooth in the arch. The most common complication of neonatal teeth or natal is traumatic ulceration of the ventral portion of the tongue due to friction, called Fede-Riga disease (ulcer). No reports of aspiration exist in the literature. The treatment of natal and neonatal teeth should be assessed very carefully to estimate their mobility, integrity, feeding baby, and the presence of some ulcers.
