Oro-facial Manifestations, Oral Health Status and Treatment Needs in Transfusion Dependent Children With β-thalassemia Major: A Cross-sectional Study

@#Introduction: β-Thalassemia is genetic disorder which clinically presents as anaemia due to decreased production of beta-chains of haemoglobin molecule. Literature on oro-facial manifestations, oral health status is sparse and inconclusive in the β-thalassemia major patients (TM). Methods: This cross-sectional study was done to assess oro-facial manifestations of β-Thalassemia. 31 TM patients in the age group of 6-18 years were clinically examined and oro-facial manifestations were recorded. Oral health status including oral hygiene status, dental caries, gingival status of these TM children was compared with 42 healthy children. The mean values were compared using Student’s t-test. Treatment needs of both the groups were recorded using WHO oral health assessment form. Results: Lip incompetence (38.75%) and maxillary protrusion (19.35%) were most common oro-facial manifestations of Thalassemia major. Mean OHI-S score for TM and healthy children were comparable 1.73 ± 1.10 and 1.36 ±1.17 respectively (p=.178) but mean GI score for TM was higher than healthy children, 1.42±.39 and .94±.51 respectively (p<.05). Mean DMFT scores for TM and healthy children were 1.5±1.8 and 1.2±2.1 respectively (p=.578). Treatment needs was relatively higher among TM children with 58% of these children requiring one surface filling. Conclusion: Lip incompetence followed by maxillary protrusion were most common oro-facial manifestations of Thalassemia major. There is no significant association between oral hygiene and dental caries with Thalassemia major. However, thalassemia major is associated with gingivitis. Treatment requirement was relatively higher among TM children with one surface filling being the commonest need.

Asociación entre enfermedad periodontal y parto pretérmino en un grupo de mujeres puérperas del norte de México / Association between periodontal disease and preterm birth in a group of puerperal women from northern of Mexico

Introducción: La enfermedad periodontal puede ser causa de lesiones sistémicas. Se conoce la prevalencia de enfermedad periodontal en mayores de 35 años y el aumento de los factores de riesgo en mujeres embarazadas, pero no se sabe si estos factores se potencializan en mujeres embarazadas menores de 35 años. En México son muy prevalentes tanto el embarazo en mujeres jóvenes como el parto pretérmino. Con el objetivo de conocer la prevalencia de la enfermedad periodontal y su asociación con el parto prematuro, se realizó este estudio en mujeres puérperas menores de 35 años en una población abierta. Material y métodos: Estudio de tipo observacional, descriptivo y transversal, analizando casos y controles. La población de estudio fueron pacientes puérperas entre 17 y 35 años que ingresaron a un hospital público durante parte del año 2019. Se utilizó el índice de necesidad de tratamiento periodontal en la comunidad (CPITN, por sus siglas en inglés) para la medición de enfermedad periodontal (EP), se consideró embarazo prematuro (PP) cuando el parto ocurrió con menos de 37 semanas de embarazo. Como covariables se consideraron edad, tabaquismo y paridad. Se buscó la asociación mediante regresión logística para el cálculo de la razón de momios. Resultados: Se analizaron 323 mujeres, 200 (62%) tuvieron niveles 3 y 4 CPITN; 10.8% (35) tuvieron parto prematuro, la razón de momios cruda para la asociación entre código CPITN 3 y 4 y parto prematuro fue de 3.3 (p < 0.01). Después de ajustar por otros predictores la asociación se mantuvo en 3.8 (p < 0.01). Conclusiones: Es la primera vez en nuestro medio que se encuentra esta asociación entre enfermedad periodontal y parto prematuro. La prevalencia de parto prematuro en este grupo fue más alta que la media nacional. Es necesaria la revisión odontológica durante las visitas prenatales. Debe continuarse la línea de investigación con un estudio prospectivo (AU)

Introduction: Periodontal disease can cause systemic injuries. Prevalence of periodontal disease in people older than 35 years old is known, as well as the risk factors for pregnant women; however, it is not known if these factors also apply for pregnant women younger than 35 years of age. In Mexico, pregnancy among young women and preterm birth are very prevalent. The present study was done with the objective of finding out the prevalence of periodontal disease and its relationship with preterm birth in puerperal women younger than 35 years old in a population without social security. Material and methods: The study is observational, descriptive and transversal, analysis type cases and controls was done. The population for the study consists on puerperal patients between the ages of 17 to 35 years, all of them were admitted into a public hospital in a period of 2019. The Community Periodontal Index of Treatment Need (CPITN) was used to measure periodontal disease in the patients. Preterm birth was defined as a birth occur before 37 weeks of pregnancy. Age, smoking and parity were used as covariables. Logistic regression was used to evaluate the association between periodontal disease and preterm birth through odds ratio values. Results: 323 women were analyzed, 200 (62%) had levels of 3 and 4 on the CPITN. 10.8% (35) had preterm birth, the raw odds ratio for the association between the codes 3 and 4 from the CPITN was of 3.3 (p < 0.01), after adjusting other predictors the association was 3.8 (remaining as a p < 0.01). Conclusions: It is the first time that such an association between periodontal disease and preterm birth has been found in the region. Prevalence of preterm birth in the group studied was higher than the national's average. An odontological revision during prenatal visits is needed. This line of research should be continued through a prospective study (AU)

Oral Health Impact Profile (OHIP-14) and its association with dental treatment needs of adolescents in a rural Nigerian community

Aim: To validate and determine the applicability of OHIP-14 in assessing the impact of unmet dental treatment needs on the quality of life of adolescents in a rural community. Methods: The OHIP-14 questionnaire and the Aesthetic component (AC) of Index of Orthodontic Treatment Need (IOTN) were data collection instruments in a cross sectional survey among students in a rural community. The reliability and validity of the OHIP-14 as well as the association between it and dental treatment needs including malocclusion was assessed. Data obtained was analyzed using Mann Whitney U Test. Results: The mean age of participants was 14.9 (±1.6) years. The OHIP-14 had acceptable Cronbach alpha value of 0.8. It could discriminate between respondents with or without dental treatment needs due to caries and dental trauma (p <0.001). The OHIP-14 did not differentiate between respondents with or without orthodontic treatment need (p= 0.808). However, significant association existed between being irritable with people and unmet orthodontic treatment needs (p= 0.032). Conclusion: The OHIP-14 is a valid and reliable quality of life assessment tool in young adolescents in this rural community. However, only the social disability domain component discriminated significantly between those with or without orthodontic treatment needs. (AU)

Oral health status and treatment need among institutionalized elderly in India.

Aim: To assess the oral health status and treatment needs among elderly people aged 60 years and above residing as inmates in the old age homes of Hyderabad and Secunderabad, Andhra Pradesh, India. Settings and Design: A cross‑sectional study was performed to determine the oral health status and treatment needs among elderly people. Materials and Methods: In order to assess the oral health status and treatment needs, the clinical assessment of oral mucosa, community periodontal index, loss of attachment, dentition status and treatment need, prosthetic status and prosthetic need was recorded based on a modified World Health Organization 1997 proforma. Statistical Analysis Used: Multi‑group analysis was done using analysis of variance. P < 0.05 was considered statistically significant. Results: Of the 812 inmates, 431 (64.0%) of the study participants had oral mucosal lesions. In terms of periodontal status, all sextants were excluded (Code “X”) in 324 (39.9%) subjects. Out of dentate population, a majority of the inmates (219; 27.0%) presented with deep pockets (Code “4”) followed by shallow pockets (Code “3” ‑ 183; 22.5%). The majority of the subjects had no prosthesis in the upper arch (85.0%) and lower arch (86.6%). Conclusion: The study demonstrated poor oral health among institutionalized elderly inmates. Oral mucosal lesions were found to be higher and periodontal status was also poor amongst the study population.

Grado de concordancia de los índices más utilizados en estudios epidemiológicos de la enfermedad periodontal / Level of agreement of the most used indexes in epidemiological studies for periodontal disease

INTRODUCCIÓN El estudio de la enfermedad periodontal (EP) ha presentado resultados imprecisos y heterogéneos debido a diversos factores, entre ellos, los métodos usados en la medición, las diferencias en el momento de definir el grado de afectación y los valores desde los cuales se consideraría que un paciente presenta EP. Existen múltiples índices periodontales utilizados frecuentemente en estudios epidemiológicos, cada uno con sus criterios y protocolos de medición. OBJETIVO Determinar la concordancia del valor de la prevalencia de la EP dada por algunos índices periodontales utilizados. MATERIALES Y MÉTODO Se realizó un estudio observacional transversal descriptivo en una población de 58 pacientes adultos de 35-44 años pertenecientes al CESFAM Lorenzo Arenas, Concepción, en el año 2013. Los examinadores fueron calibrados. Se realizó un examen con registro de boca completa midiendo 6 sitios por diente, con exclusión de los terceros molares, para medir pérdida de inserción clínica, profundidad de sondaje y hemorragia al sondaje. Los resultados se analizaron mediante el programa estadístico EPIDAT 3.0. RESULTADOS Se determinaron unos valores de prevalencia de EP muy distintos entre los indicadores evaluados, obteniéndose una variación de incluso 31 puntos en una escala porcentual. El análisis de la concordancia de los índices periodontales con el indicador CDC/AAP mostró que tanto ICEP, como CPI y CPITN lograron un buen valor kappa. CONCLUSIÓN A pesar de la gran diversidad de los índices con respecto a su formulación, se observó cierta concordancia entre algunos de ellos.

INTRODUCTION The study of periodontal disease (PD) has shown inaccurate and heterogeneous results due to various factors, among them: most used methods to measure the illness, differences at the time of deciding the level in which it affects patients and the values from which a patient would be considered to suffer from PD. There are numerous periodontal indexes frequently used in epidemiological studies, each one with different criteria and measurement protocols. OBJECTIVE To establish the agreement in PD prevalence value given by some periodontal indexes used. MATERIALS AND METHOD A descriptive cross-sectional observational study was conducted on 58 adult patients between 35-44 years old belonging to Lorenzo Arenas Primary Health Care Center in Concepcion during the year 2013. All examiners who participated in the study were calibrated. A full mouth registration exam was carried out, measuring 6 places per tooth, not including the third molars, in order to measure the clinical attachment loss, probing depth, and bleeding on probing. The results were analyzed using EPIDAT 3.0 statistical program. RESULTS Very different PD prevalence values were obtained using the measured indicators, having a variation of up to 31 points in a percentage scale. The analysis of the agreement in periodontal indexes with the CDC/AAP indicator showed ICEP, CPI and CPITN scored a good kappa value. CONCLUSION Despite the great diversity of the indices with respect to their formulation, some correlation between them was observed.

Periodontal Treatment Needs and Oral Ulceration in Children and Adolescents with Celiac Disease.

Aim: To determine periodontal treatment needs and the incidence of oral ulceration among children and adolescents with celiac disease and to compare their findings with a healthy age and gender-matched control group. Methods: A prospective study was conducted at King Hussein Medical Center on a total of 86 patients: 43 patients with celiac disease as the study group (comma removed) and 43 healthy age and gender-matched participants as the control group. Both groups were questioned for a history of recurrent mouth ulcers (comma removed) and the frequency of tooth brushing. The dental examination for each patient in both groups included the following: plaque index, gingival index (comma removed) and Community Periodontal Index of Treatment Needs (CPITN). The oral mucosa was examined clinically for any lesion consistent with aphthous ulceration. Results: There were 26 females and 17 males in each group, with a mean age of 13.2 and 13.3 years respectively. Plaque scores were significantly higher among the study group (p<0.05) while the difference in the gingival scores was not statistically significant (p>0.05). Recurrent aphthous ulceration (RAS) was positive among 13 (30.23%) celiac patients compared to 9 (20.9%) among the control group. However, the result was not statistically significant (p>0.05). CPITN revealed no significant difference between the two groups although the mean index was higher among the celiac group. No one in either group scored 0, while the highest percentage in both groups scored 2. Shallow and deep pockets (scores of 3 and 4) were greater in celiac patients. Overall, the variation between the two groups was not statistically significant. Conclusion: Oral hygiene status seems worse in celiac patients, which indicates that oral health education programs may be beneficial for these children. Although the need for periodontal treatment and the frequency of RAS are higher in celiac patients, the statistical difference was not significant (p NS).

Treatment needs for Dental Caries, Restorative Care Index, and Index of Extractions in adolescents 12 and 15 years old / Necesidades de tratamiento para Caries Dental, Indice de Cuidados Restauradores, e Índice de Extracciones en adolescentes de 12 y 15 años de edad

OBJECTIVE: To determine the Treatment Needs Index (TNI) for dental caries, the restorative Care Index (CI), and to introduce a Tooth Extractions Index (TEI) to estimate past and current treatment needs among Mexican adolescents. SUBJECT AND METHODS: A descriptive cross-sectional study was carried out on 1538 adolescents aged 12 and 15 years in the state of Hidalgo, Mexico, to collect decayed, missing, filled teeth (DMFT) data to describe TNI, CI and TEI indices. RESULTS: Higher TNI was identified in younger male teenagers who had always lived in the same community, without dental visits in the last year, and who had poorer socio-economic markers. Higher CI was found in older, female subjects who had moved in their lifetimes to a new community in the area, with dental visits in the last year and who had better socio-economic markers. Higher TEI was found in older, female teenagers who had moved in their lifetimes to a new community in the area, without dental visits in the last year, and who had worse socio-economic markers. CONCLUSIONS: We observed high rates of treatment needs for dental caries and little experience of restorative treatment. While dental extractions due to advanced caries should ideally be zero, relatively few adolescents had this treatment experience. Despite the fact that the overall background of these adolescents is rather homogeneous, it was still possible to find that treatment needs'indices (past and present needs) appeared to be modified by sociodemographic and socio-economic variables.

OBJETIVO: Determinar las necesidades de tratamiento para caries dental (INT), el índice de cuidados restauradores (IC) así como proponer un índice que haga referencia a las extracciones dentales (IE), para estimar necesidades de tratamiento actual y pasada en adolescentes mexicanos. MATERIAL Y MÉTODOS: Se realizó un estudio transversal descriptivo en 1538 adolescentes de 12 y 15 años en el Estado de Hidalgo, México. Empleando el índice CPOD se calcularon los índices TNI e IC; asimismo se propone un IE a las que ha estado expuesta la población. RESULTADOS: El INT fue mayor en los de 12 años, hombres, los que vivieron siempre en la misma comunidad, que no tuvieron visita al dentista en el último año, y con marcado nivel socioeconómico bajo. El IC fue mayor en los sujetos de 15 años, las mujeres, con migración interna, que si tuvieron visita al dentista en el último año, y con mejor nivel socioeconómico. El IE fue mayor en los de 15 años, mujeres, con migración interna, que no tuvieron visita al dentista en el último año, y con peores condiciones socioeconómicas. CONCLUSIONES: Se observaron altas necesidades insatisfechas de tratamiento para caries dental y poca experiencia de tratamiento restaurador. Las extracciones se observaron en pocos adolescentes, considerando cero como ideal. A pesar de que los antecedentes de estos adolescentes es bastante homogéneo, fue posible encontrar que los índices de necesidades de tratamiento (necesidades presentes y pasadas) parecen ser modificados por variables socio-demográficas y socioeconómicas.

Prosthodontic status and needs of elderly institutionalized residents in Mangalore: A prospective study.

Aim: The aim of the present study is to assess the prevalence of Kennedy's classification, status of existing prosthodontic appliances if any, awareness of the subjects regarding various treatment options, and treatment needs in a group of elderly institutionalized residents. Materials and Methods: The subjects were selected from various old age homes present in Mangalore city, with ages ranging from 60 to 80 years. The subjects were interviewed and examined by a single trained examiner and findings were recorded on a clinical case history report sheet. Results: Kennedy's class I was most prevalent and class IV the least. Among the subjects examined, only 12.4% were wearing prosthesis. Based on the Nevalainen's index and Karslon's index, most of the prosthodontic appliances were found to be in poor condition. 86% of the subjects were in need of prosthodontic treatment. 75% of the subjects interviewed were unaware of the treatment options available. Conclusion: The elderly patients living in institutions do not achieve a deserving and satisfactory oral health care. The oral care assistance in institutionalized elderly patients has been an unfulfilled service.

Dental caries prevalence and treatment needs among 12- and 15- Year old schoolchildren in Shimla city, Himachal Pradesh, India.

Context: Dental caries is one of the commonest oral diseases in children. Despite this fact, not many studies have been done on this issue among school children in Shimla. Aim: To assess the prevalence of dental caries and treatment needs among schoolchildren aged 12 years and 15 years in Shimla city, Himachal Pradesh, India. With this study we also aimed to establish reliable baseline data. Design: Cross-sectional study. Materials and Materials: This study was conducted among 12 - and 15 - year old schoolchildren in Shimla city, Himachal Pradesh-India. A sample of 1011 schoolchildren was selected by a two-stage cluster sampling method. Clinical recording of dental caries, was done according to WHO diagnostic criteria (1997). Statistical Analysis: The statistical tests used were the t- test, and the Chi-square test. Results: The prevalence of dental caries was 32.6% and 42.2% at 12 years and 15 years respectively. At 12 years of age, the mean Decayed Missing Filled Teeth was 0.62 ± 1.42 and it was 1.06 ± 2.93 at 15 years of age. Females had higher level of caries than males at both the ages. Dental caries was higher in children from government schools as compared to those from private schools. The 'decayed' component was the biggest contributor to the DMFT index. The highest treatment need at both ages was one surface restoration. Conclusion: The caries experience of 12- and 15- year-old children was low compared to WHO - 'recommended' values. Effective oral health promotion strategies need to be implemented to further improve the dental health of school children in Shimla city.

Status of dental health in chemical warfare victims: The case of Isfahan, Iran.

Background: Little evidence is available regarding the dental health of victims of chemical warfare in Iran. Therefore, in this study, we examined the decayed, missing, and filled teeth index (DMFT), community periodontal index of treatment needs (CPITN), and saliva secretion rate of chemical warfare victims living in the province of Isfahan in Iran. Materials and Methods: This case-control study was conducted with 300 chemical warfare victims as the treatment group and 300 age-matched individuals without exposure to chemical warfare as the control group. DMFT and CPITN indices and saliva secretion rate were measured and compared between the two groups. Results: Chemical warfare victims had significantly higher scores than the control group for decayed teeth (4.25±3.88 vs 3.52±2.81; P=0.009), missing teeth (8.79±9.3 vs 6.15±8.43; P<0.001), total DMFT index (17.00±6.72 vs 13.20±6.89; P<0.001), and CPTIN (2.81±0.81 vs 1.71±1.04; P<0.001). However, no significant difference was observed between the two groups in filled teeth (4.00±4.2 vs 3.59±2.48; P=0.148). The level of saliva secretion in warfare victims was significantly lower than that in the control group (1.71±0.05 vs 3.85±1.95 cc/5 min; P<0.001). Conclusion: Chemical warfare victims have relatively poor dental/oral health. Chemical injury might cause a dysfunction in saliva secretion, with decrease in saliva secretion increasing the risk for tooth decay and periodontal disorders. Further research is required to find out the exact underlying mechanisms and the factors associated with poor dental/oral health in chemical warfare victims.

El objetivo del estudio es estimar los recursos odontológicos para resolver las necesidades de tratamiento de los adolescentes de 12 años de Chile, pertenecientes a los niveles socio económicos alto, medio y bajo. El estudio se realizó a partir de los resultados del "Estudio Diagnóstico Nacional de Salud Bucal del Adolescente de 12 Años y Evaluación del Grado de Cumplimiento de los Objetivos Sanitarios de Salud Bucal 2000-2010", proyecto FONIS el que fue realizado en una muestra de 2.232 adolescentes de 12 años, con representación regional proporcional a la población nacional. Para estratificar por nivel socioeconómico este estudio se usó la clasificación y ranking de pobreza por comuna de MIDEPLAN y la caracterización por NSE de los establecimientos del Ministerio de Educación Se calculó el recurso humano necesario mediante la aplicación de estándares de rendimiento del ministerio de salud, comparando estos parámetros en el eje de nivel socioeconómico. Se observan diferencias estadísticamente significativas en las necesidades de tratamiento entre los NSE, concentrándose la mayor necesidad en los grupos de NSE bajo y medio.

The aim of this study is to determine oral health care delivery team workforce necessary to tackle oral health treatment needs of 12-year-old adolescents from different socioeconomic status. The sample consisted of 2.232 individuals. There was a proportional representation of the Nation)s regions. The Socioeconomic status (SES) was stratified through the MIDEPLAN)s poverty municipality ranking and by means of description of SES of the selected school by the Ministry of Education. To determine oral health treatments needs we carried out dental examination and WHO diagnosis criteria were used. We calculated the oral health care delivery team workforce based on Ministry of Health recommendations and compare among SES. Differences upon health care delivery team workforce necessary to tackle oral health treatment needs of 12-year-old adolescents from different socioeconomic status were evident.

Prevalence of malocclusion and orthodontic treatment needs among 16 and 17 year-old school-going children in Shimla city, Himachal Pradesh.

Background: Many studies have been conducted in India to know the prevalence of malocclusion and the orthodontic treatment needs using dental aesthetic index (DAI), but no study so far has been conducted in Shimla city, Himachal Pradesh. Objective: To know the prevalence of malocclusion and orthodontic treatment needs among 16- and 17 year-old school-going children in Shimla city, Himachal Pradesh. Materials and Methods: The study was carried out on 622 (365 boys and 257 girls) school children, aged 16 and 17 years, from February 2009 to May 2009. Type III examination was conducted and the assessment of malocclusion was done according to the DAI. Results: 20.28% of the male and 24.52% of the female students in the sample were affected with malocclusion. The mean DAI scores of the male and female children were 22.26 and 21.79, respectively. Distribution of the four DAI grades was as follows: DAI-I (no abnormality or minor malocclusion) 79.58%, DAI-II (definite malocclusion) 16.39%, DAI-III (severe malocclusion) 3.69%, DAI-IV (very severe/handicapping malocclusion) 0.34%. Conclusion: The present study shows that 20.42% of the children examined had malocclusion which required treatment.

Besides various treatment needs 49.7% required restorative treatment. Conclusion : T0 he prevalence of dental caries in Delhi school children is high with D+d components comprising of more than 95%. This indicates lack of awareness and affordability to the dental facilities available. Therefore, there is a need to develop preventive and promotional oral health strategies to combat this infectious disease.

Caries dental y necesidades de tratamiento en el primer molar permanente en escolares de 12 años de las escuelas públicas del municipio de Rionegro (Antioquia, Colombia), 2010 / Dental Caries and Treatment Needs in the First P ermanent Mol ar in 12-year-old School children fr om P ublic Schools in the Municipal ity of Rionegro (Antioquia, Colombia), 2010

Antecedentes: es importante evaluar el primer molar permanente, ya que en edad escolares el diente permanente más afectado por caries. La prevalencia de caries en estos dientesse ha asociado con la actividad futura de caries. Objetivo: determinar la prevalencia decaries y las necesidades de tratamiento de los primeros molares permanentes en la poblaciónescolar de 12 años de las escuelas oficiales del municipio de Rionegro (Antioquia).Métodos: se realizó un estudio descriptivo transversal en 808 escolares de 12 años deescuelas públicas del municipio. Se analizó la prevalencia de caries dental en el primer molarpermanente por número y tipo de dientes afectados y de acuerdo con sexo, escolaridad,zona de residencia y afiliación al Sistema General de Seguridad Social en Salud (SGSSS).También se describieron las necesidades de tratamiento para cada primer molar permanente.Resultados: los molares inferiores presentaron la mayor prevalencia de cariesdental en relación con las variables de afiliación al SGSSS, sexo y zona de residencia;en estas dos últimas variables se evidenció más afectación en el primer molar inferiorderecho y concentración en este molar de las necesidades de tratamiento restaurativo.Conclusiones: aunque se cuenta con estudios previos sobre prevalencia de caries dentalen el municipio que muestran cumplimiento de metas de la Organización Mundial de laSalud, son más escasos los estudios que evalúen de manera individual los primeros molarespermanentes para orientar políticas de salud pública dirigidos a la preservación de estasimportantes estructuras dentales...

Background: Evaluation of the first permanent molar is important since it is the tooth thatis most affected from dental cavities in schoolers. Caries prevalence of this molar has beenassociated with future caries activity. Objective: Determine caries prevalence and treatmentneeds in the first permanent molar of a 12-year-old population from public schools in themunicipality of Rionegro (Antioquia). Methods: A descriptive study in 808 12-year-old schoolchildren from public schools in Rionegro was conducted. Caries prevalence in the first permanentmolar was analyzed regarding number and type of teeth affected and associationwith sex, grade, zone of residence, and type of affiliation to the social security system (SSS).Needs for dental treatment in this molar were also described. Results: Lower molars werethe most affected by dental caries in relationship with sex, SSS, and zone of residence; in thelatter two dental cavities were more prevalent in the right lower first molar, tooth in which theneed for restorative treatment is higher than the other first molars. Conclusions: Althoughthere are previous studies on the dental health status in Rionegro and indicators show thatthe goals of the World Health Organization are being met, evaluative research focused onthe first permanent molar is scarce and necessary given its importance for health publicpolicymaking intended to preserve this teeth...

Assessment of periodontal status among dental fluorosis subjects using community periodontal index of treatment needs.

Aim: To determine the periodontal status and treatment needs among dental fluorosis subjects residing in Ennore, Chennai, using Community Periodontal Index of Treatment Needs (CPITN). Materials and Methods: All the subjects with dental fluorosis above 15 years of age, permanent residents of Ennore, were included in the study. Subjects with known systemic diseases and subjects with other intrinsic dental stains were excluded from the study. Periodontal status was estimated using CPITN and Dental fluorosis was recorded using Dean's Dental Fluorosis Index. Results: The total number of study subjects was 1075, of which 489 were males and 586 were females. Males were predominantly affected with periodontal disease than females. This was found to be statistically significant (P=0.000). The association between Degree of Fluorosis and Periodontal Status is statistically significant (P=0.000). There was statistically significant difference in mean number of sextants between the degree of fluorosis in each of the periodontal status (P=0.000). Conclusion: The finding that the lower prevalence of shallow pockets in the study area, where the fluoride level in the drinking water ranges from 1.83 to 2.01 ppm, indicates that the use of fluoride in water is beneficial to the periodontal tissues.

Dental caries experience and treatment needs in the mixed dentition in North East Malaysia

Dental caries is an important community dental health problem with limited studies in the mixed dentition stage. The aim of this study was to determine the caries prevalence and treatment needs among 7- 9 year old school children in Kelantan which is situated in North East Malaysia. A retrospective dental record review of fully documented dental records belonging to primary school children attending a paediatric dental clinic was conducted. Dental caries was recorded using dmft index and DMFT index for deciduous teeth and permanent teeth respectively. Three hundred and nineteen dental records of 175 (54.9%) boys’ and 144 (45.1%) girls’ were selected and subjected to a ‘dental record study’. The prevalence of dental caries was 93% (95% CI : 89,97) in primary dentition and 50.5% (95% CI : 42.2, 58.8) in permanent teeth. Mean dmft and DMFT was 6.2(SD 3.39) and 1.04(SD 1.34) respectively. Regarding treatment needs in the primary dentition, 35.4% of teeth needed one surface filling, 34.7% needed extraction, 24.5% needed two or more surfaces filling and 5.6% needed pulp care. In the permanent dentition, 54.7% required sealants and 21.9% required one surface restoration. The caries prevalence and treatment needs were high among this study population in the mixed dentition stage, particularly showing the early involvement of newly erupted permanent teeth. It appears that high caries prevalence in the primary dentition is a risk factor for caries in newly erupted permanent teeth. Oral health promotions programmes are required in the mixed dentition stage and may reduce the risk of caries in permanent dentition.

Criterios de evaluación odontológica pre-radioterapia y necesidad de tratamiento de las enfermedades orales post-radioterapia en cabeza y cuello / Pre-radiotherapy dental evaluation criteria and treatment needs of oral side effects after head and neck radiotherapy

El objetivo de esta revisión es presentar criterios de evaluación odontológica pre-radioterapia y cuáles son las principales necesidades de tratamiento de estos pacientes después del tratamiento de radiación. Fueron revisados artículos en inglés, español y portugués entre 1995 y 2009 indexados en Pubmed y Scielo. Las palabras claves fueron: cáncer oral y radioterapia, complicaciones de la radioterapia en cabeza y cuello, evaluación oral pre-radioterapia. Los efectos colaterales de la radioterapia en la región de cabeza y cuello pueden ser temporales o tardíos. Aquellos que son tardíos, como la caries de radiación y la osteorradionecrosis pueden estar directamente relacionados con el hecho de no haber realizado una evaluación odontológica previa y pueden afectar severamente la calidad de vida del paciente.La participación del cirujano-dentista en el equipo multidisciplinario y la evaluación odontológica de los pacientes que serán sometidos a radioterapia en la región de cabeza y cuello son de vital importancia en mejorar la calidad de vida post-operatoria de estos pacientes.

The objective of this review is to present pre-radiotherapy evaluation criteria and the main needs for treatment of these patients after the radiation therapy. Were revised articles in English, Spanish and Portuguese language between 1995 and 2009 indexed in Pubmed and Scielo. The keywords were oral cancer and radiotherapy, complications in head and neck radiotherapy, oral pre-radiotherapy evaluation.The adverse complications of radiotherapy in head and neck area could be temporary or late. The late effects, such as radiation caries and osteorradionecrosis could be directly associated with the fact that previous dental evaluation was not performed and can severely affect the post-operatory quality of life. The participation of the dentist in the multidisciplinary team and dental evaluation of the patients that will receive radiotherapy in the head and neck area are of vital importance to improve the post-operatory quality of life of these patients.
