Confirmation of symmetrical distributions of clinical attachment loss and tooth loss in a homogeneous Mexican adult male population
Background/purpose
To ascertain whether or not clinical attachment loss and tooth loss are present with similar severity and prevalence across the two sides of the mouth in a homogeneous sample of urban male adults.
Materials and methods
A cross-sectional study was carried out on 161 policemen (a largely homogeneous group in terms of ethnic background, socioeconomic status, sex, occupation, and medical/dental insurance) in Campeche, Mexico. Periodontal examinations were undertaken using the Florida Probe System in a dental chair by one trained and standardized examiner (kappa ≥ 0.60) to determine clinical attachment loss and tooth loss. We examined six sites in all teeth present in the mouth (a maximum of 168 sites, no third molars). Because of correlated data between observations, McNemar (for tooth loss) and Wilcoxon (for attachment loss) signed-rank tests were used to compare right and left sites within the same patient.
Results
The mean age was 38.4 ± 11.0 years. The mean number of teeth present was 24.4 ± 4.6; the mean number of periodontal sites/person was 146.7 ± 27.8. All P values were ≥ 0.05 (except for attachment loss in the upper first premolars), suggesting that there were no statistically significant differences between the right and left sides for the frequency of presentation of these two conditions.
Conclusion
Tooth loss and attachment loss measurements largely resemble each other on both sides of the mouth
Factores de riesgo hereditarios y socioeconómicos para labio o paladar hendido no asociados a un sÃndrome en México: estudio de casos y controles pareado
Introduction. From an epidemiological point of view, non-syndromic orofacial clefts are the most common oral congenital deformities worldwide.Objective. Family histories were traced and socioeconomic risk factors were identified for non-syndromic cleft lip with or without cleft palate.Material and methods. A case-control study was carried out with 208 cases of non-syndromic cleft lip with or without cleft palate, and matched by age and sex with 416 controls. Cases were patients attending a referral clinic from 2002 through 2004 in Campeche, Mexico. A questionnaire was administered to collect sociodemographic and socioeconomic variables as well as familial background relevant to non-syndromic cleft lip with or without cleft palate. Conditional logistic regression models were used; adjusted odds ratios and 95% confidence intervals were calculated.Results. In the multivariate model, the following risk factors were identified: 1) low socioeconomic status; 2) birth in the southern region of Campeche state; 3) home delivery or delivery in a publicly funded hospital; 4) occurrence of prior non-syndromic cleft lip with or without cleft palate cases in the father's or mother's family: 5) having a sibling with non-syndromic cleft lip with or without cleft palate; 6) the proband having another malformation, and 7) a history of infections during pregnancy. Prenatal care consisting of vitamin supplementation was a protective factor for non-syndromic cleft lip with or without cleft palate (odds ratio=0.29).Conclusions. A "social gradient in health" was seen to link oral malformation with diet components, and several socioeconomic and socio-demographic factors broadly encompassed in low socioeconomic status. Further characterization of risk factors will guide the assemblage of a pro-active counseling and prevention program for families at risk for non-syndromic cleft lip and cleft palate.Introducción. Desde el punto de vista epidemiológico, las hendiduras faciales son las deformidades orales más comunes alrededor del mundo.Objetivo. Identificar los factores de riesgo hereditarios y socioeconómicos relacionados con la presencia de labio o paladar hendido no asociados a un sÃndrome.Materiales y métodos. Se hizo un estudio de casos y controles en el que se incluyeron 208 casos con diagnóstico de labio, paladar hendido o ambos no asociados a un sÃndrome, los cuales fueron pareados por edad y sexo con 416 controles. Se incluyeron todos los pacientes quirúrgicos atendidos durante el periodo 2002-2004 en el programa estatal de labio o paladar hendido de Campeche, México. Se aplicó un cuestionario en el que se recogió información sobre variables sociodemográficas y socioeconómicas, asà como sobre antecedentes hereditarios de labio o paladar hendido no asociados a un sÃndrome en la familia. Debido a que el diseño fue pareado, el análisis se hizo con regresión logÃstica condicionada.Resultados. En el modelo multivariado para labio o paladar hendido no asociado a un sÃndrome se identificaron de forma significativa (p<0,05) los siguientes factores de riesgo: nivel socioeconómico bajo (razón de momios, RM=2,02), nacimiento en el sur del estado (RM=3,96), nacimiento en casa (RM=2,51) o nacimiento en hospital público (RM=4,08), antecedentes heredofamiliares paternos (RM=5,38), antecedentes heredofamiliares maternos (RM=4,11), tener otro hijo con labio o paladar hendido en la familia (RM=46,02), presentar algún otro defecto congénito asociado (RM=8,20) e infección en el embarazo (RM=2,90), y como factor protector, el cuidado prenatal y el uso de vitaminas (RM=0,29).Conclusiones. El mayor riesgo en nuestra muestra para labio, paladar hendido o ambos, no asociados a un sÃndrome, radica en las variables relacionadas con los antecedentes familiares y hereditarios, y las indicadoras de la posición socioeconómica. Se observó un efecto protector del manejo prenatal con vitamina
