Factors associated with the number of filled teeth in adolescents from public schools: a cohort study.

This study aimed to assess the association of demographic conditions, socioeconomic status, clinical variables, and psychosocial factors with the number of filled teeth in adolescents from public schools. This cohort study comprised 1,134 12-year-old adolescents enrolled in public schools in Santa Maria, Brazil, in 2012. They were followed-up in 2014, where 743 individuals were reassessed (follow-up rate of 65.52%) for the number of filled teeth. Data were collected via dental examinations and structured interviews. Demographic and socioeconomic characteristics were collected from parents or legal guardians. The psychosocial factor comprised students' subjective measurement of happiness (Brazilian version of the Subjective Happiness Scale - SHS). Dental examinations were performed to assess the number of filled teeth through decay, missing, and filled teeth index (DMF-T). Unadjusted and adjusted Poisson regression analyses were performed to assess the association between baseline variables and filled teeth at follow-up. The number of filled teeth in 2012 and 2014 were 193 (17.02%) and 235 (31.63%), respectively. The incidence of filled teeth in 2014 was 42 (5.65%). Adolescents with untreated dental caries, those who visited the dentist in the last 6 months, those that exhibited being happier, and those who had filled teeth at baseline were associated with a higher number of filled teeth at follow-up. We conclude that the number of filled teeth in adolescents was influenced by clinical and psychosocial factors, emphasizing the need to focus on oral health policies in individuals with higher disease burden and those who feel psychologically inferior.

Time expended on managing molar incisor hypomineralization in a pediatric dental clinic in Nigeria.

This study assessed the difference in the number of visits made to a dental care clinic and the time spent providing specific dental treatment for children with and without molar incisor hypomineralization (MIH). Children aged 8 to 16 years who presented at the Pediatric Dental Unit of the Obafemi Awolowo University Teaching Hospital Complex, in Ile-Ife, Nigeria, were eligible for the study. A comprehensive medical and dental history was taken, and each child was clinically examined, diagnosed, and treated according to a drawn-up plan. The time taken to establish a diagnosis and to provide specific treatments (scaling and polishing, restoration, pulpectomy, extraction, and placement of stainless steel crowns) and the number of visits made to complete the treatment plan were recorded for each child. Differences in the number of visits, time expended to make a diagnosis and to treat children with and without MIH were analyzed. The average time for diagnosis (p = 0.001) and the average time for placing amalgam restorations (p = 0.008) were significantly longer in children with MIH than in those without it. Children with MIH made more visits to the clinic (p < 0.001).There was no significant difference in the average time for scaling and polishing (p = 0.08), glass ionomer cement restorations (p = 0.99), composite restorations (p = 0.26), pulpectomy (p = 0.42), tooth extraction (p = 0.06), and placement of a stainless steel crown (p = 0.83) in children with and without MIH. In conclusion, children with MIH required more time for oral health care. Placing amalgam restorations took significantly longer than placing tooth bonding restorative materials in children with MIH than in those without it.

Reports of uncontrolled clinical trials for directly placed restorations in vital teeth.

Uncontrolled trials are criticized as unreliable. This study aimed to establish how the number of published reports from uncontrolled clinical trials compares to that of controlled trials for directly placed restorations in vital teeth and whether their annual number is increasing, stable or decreasing. PubMed was searched and suitable citations of uncontrolled and controlled trial reports published between 1990-2016 were included. Reference check and hand searching were conducted. The median annual report number with 25 and 75% percentile was calculated for both types of trials. 695 reports were found. The median number of reports per year was 4 (3-7) and 22 (15-26) from uncontrolled and controlled trials, respectively. A statistically significant decreasing ratio of uncontrolled to controlled trial reports was observed (p = 0.01) by linear regression analysis. The number of reports of uncontrolled clinical trials listed in PubMed over the last 27 years appears at least five times smaller than that of controlled clinical trials and its number in relation to that of controlled trials seems to decrease over time.

Caries status in young Colombian children expressed by the ICCMS™ visual/radiographic combined caries staging system.

OBJECTIVE: To report (1) the caries experience prevalence and mean, and the caries severity and distribution patterns, expressed clinically and combined with radiographs with the conventional and ICCMS™ systems in young children from Bogotá, Colombia; (2) the contribution of including radiographs to the clinical caries scoring and (3) in which surfaces the radiograph adds to the clinical caries registration. MATERIAL AND METHODS: Six hundred children from kindergartens/schools were enrolled: Cohort A: 2-year (n = 200), Cohort B: 4-year (n = 200) and Cohort C: 6-year (n = 200) olds. Radiographs were taken of the 4- and 6- year olds. Children were examined clinically using the Clinical (C) and Radiographic (R) ICCMS™-epi Caries Scoring Systems, staging caries lesions (d) as: Initial (Cepi/RA), Moderate (CM/RB) or Extensive (CE/RC). Caries experience including missing (m) and filled (f) surfaces was expressed as follows: clinical conventional (CdMEmfs); clinical ICCMS™ (CdepiMEmfs); combined conventional (C + RdMEmfs) and combined ICCMS™ (C + RdepiMEmfs). RESULTS: The prevalence of CdMEmfs was: Cohort A: 32%; Cohort B: 59%; Cohort C: 67.5%, increasing to 73.5%, 99.8% and 100%, respectively, with the C + R depiMEmfs. The CdMEmfs means doubled when initial caries lesions (Cdepi) and radiographs (R) were included. The d component corresponded to over two-thirds of the caries experience. Findings on the radiographs significantly raised caries experience prevalence and means (p < .02), detecting primarily approximal lesions. Surfaces with highest caries frequency were occlusal/approximal of molar teeth and buccal of upper incisor teeth. CONCLUSION: Participants' caries experience was high. The radiographic assessment significantly contributed to caries experience. Molar and upper incisor teeth were most prone to caries.

Restauración post-endodoncia y condición social como factor de preservación dentaria: parte 1 / Post-endodontic restoration and social condition as afactor of tooth preservation. part 1

El objetivo de este estudio fue conocer el estado dental de piezas endodonciadas en correlación conlas variables de restauración coronaria, nivel de estudio, condición laboral y acceso a servicios odontológicos. Para ello, se analizó una población de individuos, compuesta por sujetos concurrentes a los cursos de posgrado de Endodoncia del Círculo Odontológico de Córdoba y al servicio de la Cátedra“B” de Endodoncia de la Facultad de Odontología de la Universidad Nacional de Córdoba. Se hicieron tratamientos controlados durante dieciocho meses. La muestra total la conformaron 144 pacientes y se trataron 174 casos. Sólo asistieron a control el 48,6 por ciento de los pacientes, de los cuales se evaluaron 89 dientes. El estudio mostró 37 casos con restauración coronaria definitiva sin fracturas, 52 dientes sinrestauración, 21 con fracturas y 1 se perdió. Se observó un incremento de fracturas en control a los 18 meses. La tasa de fracturas evidenció un mayor porcentaje en pacientes con nivel de estudio alto, menor en pacientes sin trabajo, y mayor en pacientes con trabajo estable y precario. El tipo de atención no se diferenció, pero los porcentajes observados sugieren que los atendidos en asistencia pública tendrían más probabilidad de fracturas. Se observó un mayor porcentaje de restauraciones definitivas enatención privada y menor en consultorios públicos. El elevado porcentaje de inasistencia a controlesmotivó un análisis específico, del cual se pudo concluir que a mayor estabilidad laboral, de estudios yde asistencia privada, mayor fue la asistencia a controles. Estos datos revelan información importantepara establecer políticas públicas de la atención posendodoncia.

The aim of this study was to know the dental state of endodontic pieces in correlation with different variables such as coronary restoration, level of study, employment status and access to dental services.To do so, we analyzed a population composed of subjects who participated in two different graduate courses at the Círculo Odontológico de Córdoba and the “Chair B” of Endodontics of the Faculty ofDentistry, National University of Córdoba. Treatments were clinically and radiographically controlled for eighteen months. The total sample included 144 patients and 174 treatments. Only 48.6% patients attended the control, 89 teeth of whom were evaluated. The study showed 37 cases with definitivecoronary restoration without fractures, 52 teeth without restoration, 21 with fractures, and 1 was lost.The fracture rate showed an increase in patients with high level of study, a decrease in unemployed patients, and an increase in both patients with stable and precarious work. The kind of attention didnot differ, but the observed percentages suggest that patients treated in public services would be morelikely to suffer from fractures. There was a higher percentage of definitive restorations in private services,and lower in public ones. The high percentage of non-attendance to controls motivated a specific analysis, from which it is possible to conclude that the more job stability, studies and private access todental services, the more the attendance to controls. These data reveal important evidence in order to establish public policies of post-endodontic services.

Restauración post-endodoncia y condición social como factor de preservación dentaria: parte 2 / Post-endodontic restoration and social condition asa factor of tooth preservation. Part 2

El objetivo de este estudio fue conocer el estado dental de piezas endodonciadas en correlación conlas variables de restauración coronaria, estado periodontal, nivel de estudio, condición laboral y acceso a servicios odontológicos. Para ello, se analizó una población de individuos compuesta por sujetos concurrentes a los cursos de posgrado de Endodoncia, del Círculo Odontológico de Córdoba, y al servicio de la Cátedra “B” de Endodoncia de la Facultad de Odontología, Universidad Nacional de Córdoba. Se hicieron tratamientos controlados durante dieciocho meses. La muestra total la conformaron 144 pacientes y se trataron 174 casos. El estudio mostró 37 casos con restauración coronaria definitiva sin fracturas, 52 dientes sin restauración, 21 con fracturas y 1 se perdió. De los dientes restaurados, el55,6 por ciento mostraron periodonto normal; 22,2 por ciento gingivitis, y 22 por ciento periodontitis leve. De los dientes sin restauración, el 3,9 por ciento mostraron periodonto normal; 7,8 por ciento gingivitis; 31,4 por ciento periodontitis leve; 35,3 por ciento periodontitis grave y 21,6 por ciento periodontitis complicada. De los dientes fracturados, el 16,7 por ciento mostraron periodonto normal o gingivitis; 35,3 por ciento periodontitis leve y grave, y un 72,7 por ciento periodontitis complicada. No se demostró asociación entre nivel de estudios, condición laboral y tipo de atención con fracturas de los pacientes, pero los porcentajes sugieren más probabilidad de sufrir fractura en los pacientes de la asistencia pública. El elevado porcentaje de inasistencia a control motivó un análisis específico, del cual se pudo concluir que cuanto más grave la patología periodontal, mayor el porcentaje de inasistencia. El estudio permitió observar desigualdad en el acceso a los servicios odontológicos, dientes no rehabilitados y con compromiso periodontal.

The aim of this study was to know the dental state of endodontic pieces in correlation with different variables such as coronary restoration, periodontic condition, level of study, employment status and access to dental services. A population composed of patients treated in two different postgraduate courses at the Círculo Odontológico de Córdoba and Chair “B” of Endodontics, Faculty of Dentistry,National University of Córdoba were analyzed. Treatments were clinically and radiographicallycontrolled for eighteen months. The total sample included 144 patients and 174 treatments. The studyshowed 37 cases with definitive coronary restoration without fractures, 52 teeth without restoration,21 with fractures, and 1 was lost. From restored teeth, 55.6% showed normal periodontium, 22.2%gingivitis, and 22% mild periodontitis. From teeth without restoration, 3.9% showed normalperiodontitis, 7.8% gingivitis, 31.4% mild periodontitis, 35.3% severe periodontitis and 21.6%complicated periodontitis. From fractured teeth, 16.7% showed normal periodontitis or gingivitis, 35.3% had mild and severe periodontitis, and 72.7% had complicated periodontitis. There has beenno correlation between level of education, work status, and kind of service on patient with fractures,but the percentage suggest that patients in public assistance are more likely to suffer fracture. The highpercentage of non-attendance to control led to a specific analysis, from which it is possible to concludedthat the more severe the periodontal disease, the greater the percentage of non-attendance. The study showed inequality in access to dental services, un rehabilitated teeth and with periodontal compromise.

Prevalence of Enamel Developmental Defects and Relationship with Early Childhood Caries in Trinidad.

PURPOSE: The purpose of this study was to describe the prevalence of developmental defects of enamel (DDE) and their relationship with early childhood caries (ECC) among preschool children in Trinidad. METHODS: A cross-sectional oral health survey of 251 three- to five-year-old preschool children was undertaken in central Trinidad. The decayed, missing, and filled primary teeth (dmft) index and the DDE index were used to measure visible caries experience and enamel developmental defects, respectively. RESULTS: Sixty-three children (25.1 percent) had some type of DDE. The most common defects were diffuse opacities and demarcated opacities. A greater severity of visible caries experience was associated with enamel opacities and hypoplasia (P<0.05). CONCLUSIONS: DDEs are prevalent among this group of preschool children in Trinidad and are risk factors for ECC, which emphasizes the importance of preventive oral health care in early childhood for these high-risk children.

Objetivos: describir la supervivencia y estado post-1 año de restauraciones con ionómero vítreo (IV) realizadas por recurso humano preprofesional y analizar la asociación entre el estado de las mismas y variables intervinientes. Métodos: se evaluaron 129 restauraciones (en 54 escolares; edad: 6 y 7 años) con IV (Ketac Molar Easymix), realizadas por estudiantes del último año de la carrera de odontología en un programa escolar con un a técnica sistematizada basada en los criterios de la restauración atraumática. Para la evaluación, cuatro examinadores basaron sus observaciones en el criterio de Franken que establece 7 categorías: 0= presente en buenas condiciones, 1= ligero defecto marginal, 2= ligero desgaste, 3= defecto marginal >0,5 mm, 4= desgaste >0,5 mm, 5= restauración partida o parcialmente perdida y 6= no presente. Para su análisis descriptivo, fueron reagrupadas en 3 categorías en términos de necesidad de reintervención: N1 (0 y 2) no necesita reintervención, N2 (1 y 3) necesita mínima intervención y N3 (4, 5 y 6) requiere reemplazo. Se consideran variables intervinientes: dentición, extensión de la cavidad y presencia de lesiones activas de caries en la cavidad bucal post-1 año clínica. Se calcularon las distribuciones de frecuencia y se estudió asociación con la prueba de Chi cuadrado. Resultados: la tasa de supervivencia post -1 año fue de 94,6 por ciento. El estado de las restauraciones mostró asociación significativa con la presencia de actividad de caries en boca en el momento de la evaluación. Conclusiones: la tasa de supervivencia de las restauraciones con IV post-1 año realizadas por recursos humano preprofesional supervisado, fue alta. La presencia de actividad de caries en boca podría ser una variable del estado de las restauraciones

Oral Health Education Program on Dental Caries Incidence for School Children.

OBJECTIVE: This 3-year retrospective controlled clinical trial assessed the effect of a school-based oral health education program on caries incidence in children. STUDY DESIGN: A total of 240 students, aged 5 to 7 years, from two public schools in Monte Sião, Brazil, were included in this study. A school-based oral health education program was developed in one of the schools (experimental group), including 120 students, while the 120 students from the other school did not participate in the program (control group). All children were initially examined for dental caries (dmf-t), and after 3 years, 98 children from the experimental group and 96 from the control group were again examined and answered a questionnaire on oral health issues. The between-groups difference in caries incidence on permanent teeth was calculated using Poisson regression analyses. Logistic regression was used to observe the association between caries incidence and other variables. RESULTS: More students from the experimental group stated knowing what was dental caries and declared that they use dental floss daily, but no significant differences in caries incidence was observed between the experimental and control groups. CONCLUSION: The school-based oral health education program is not adequately efficient to decrease caries incidence after three years, but some issues about oral health knowledge could be slightly improved.

Preference for using posts to restore endodontically treated teeth: findings from a survey with dentists.

The aim of this study was to evaluate if clinical experience, whether in relation to length of practice time and/or level of specialization influences the dentist's preference for using posts to restore endodontically treated teeth. A cross sectional study was carried out using a questionnaire with dentists (n = 276) in Pelotas, southern Brazil. Data were collected regarding clinical experience, post-graduate training, and variables related to restorations (posts/cements and use of rubber dam) for endodontically treated teeth. The data were submitted to a descriptive analysis and associations were tested. The response rate was 68%. Cast metal posts (24.53%), glass fiber posts (20.75%) and resin cement (66.67%) were the most commonly selected materials. In relation to rubber dams, 93.05% of the dentists were found not use them to lute posts. There was a significant association between the level of training of post-graduate dentists and the type of post used (p = 0.027), in that dentists without post-graduate training used cast metal posts more frequently, whereas dentists with post-graduate training reported glass fiber posts as their first choice. The results of the study showed that dentists preferred cast metal posts, glass fiber posts and resin cement. Continuing education influenced the decision of the dentists on their choice of dental posts.

Periradicular lesions in HIV-infected patients attending the faculty of dentistry: clinical findings, socio-demographics status, habits and laboratory data - seeking an association.

OBJECTIVE: The purpose of this study was to estimate the prevalence of periradicular lesions in HIV-infected Brazilian patients and to assess the correlation of several factors with the periradicular status. METHOD: One hundred full-mouth periapical radiographs were evaluated. A total of 2,214 teeth were evaluated for the presence of periradicular lesions, caries lesions, coronal restorations, pulp cavity exposure and endodontic treatment. RESULTS: The prevalence of periradicular lesions was 46%. There were no significant differences between individuals with or without periradicular lesions with respect to their socio-demographic status, habits, laboratory data and route of HIV infection. However, the presence of a periradicular lesion was statistically correlated with the number of teeth with endodontic treatment (p = 0.018), inadequate endodontic treatment (p = 0.025), images suggesting pulp cavity exposure (p = 0.002) and caries lesions (p = 0.001). CONCLUSIONS: The prevalence of periradicular lesions in HIV-infected individuals was 46% and was not related to HIV infection.

Assessing caries status according to the CAST instrument and WHO criterion in epidemiological studies.

BACKGROUND: The Caries Assessment Spectrum and Treatment (CAST) is a new epidemiological instrument for detection and treatment of dental caries. Worldwide, the WHO criterion constitutes the epidemiological tool most commonly used for caries detection. The objective of the present study is to determine the levels of similarity and difference between the CAST instrument and WHO criterion on the basis of caries prevalence, dmf/DMF counts, examination time and reporting of results. METHODS: An epidemiological survey was carried out in Brazil among 6-11-year-old schoolchildren. Time of examinations was recorded. dmft, dmfs, DMFT and DMFS counts and dental caries prevalence were obtained according to the WHO criterion and the CAST instrument, as well the correlation coefficient between the two instruments. RESULTS: Four hundred nineteen children were examined. dmft and dmfs counts were 1.92 and 5.31 (CAST), 1.99 and 5.34 (WHO) with correlation coefficients (r) of 0.95 and 0.93, respectively. DMFT and DMFS counts were 0.20 and 0.33 (CAST), 0.19 and 0.30 (WHO), with r = 0.78 and r = 0.72, respectively. Kappa coefficient values for intra-examiner consistency were CAST = 0.91-0.92; WHO = 0.95-0.96 and those for inter-examiner consistency were CAST = 0.90-0.96; WHO = 0.94-1.00. Mean time spent on applying CAST and WHO were 66.3 and 64.7 sec, respectively p = 0.26. The prevalence of dental caries using CAST (codes 2, 5-8) and the WHO criterion for the primary dentition were 63.0% and 65.9%, respectively, and for the permanent dentition they were 12.7% and 12.8%, respectively. CONCLUSIONS: The CAST instrument provided similar prevalence of dental caries values and dmf/DMF counts as the WHO criterion in this age group. Time spent on examining children was identical for both caries assessment methods. Presentation of results from use of the CAST instrument, in comparison to WHO criterion, allowed a more detailed reporting of stages of dental caries, which will be useful for oral health planners.

Periradicular lesions in HIV-infected patients attending the faculty of dentistry: clinical findings, socio-demographics status, habits and laboratory data - seeking an association

OBJECTIVE: The purpose of this study was to estimate the prevalence of periradicular lesions in HIV-infected Brazilian patients and to assess the correlation of several factors with the periradicular status. METHOD: One hundred full-mouth periapical radiographs were evaluated. A total of 2,214 teeth were evaluated for the presence of periradicular lesions, caries lesions, coronal restorations, pulp cavity exposure and endodontic treatment. RESULTS: The prevalence of periradicular lesions was 46%. There were no significant differences between individuals with or without periradicular lesions with respect to their socio-demographic status, habits, laboratory data and route of HIV infection. However, the presence of a periradicular lesion was statistically correlated with the number of teeth with endodontic treatment (p = 0.018), inadequate endodontic treatment (p = 0.025), images suggesting pulp cavity exposure (p = 0.002) and caries lesions (p = 0.001). CONCLUSIONS: The prevalence of periradicular lesions in HIV-infected individuals was 46% and was not related to HIV infection. .
