Assessment of oral health knowledge among the medical graduates of private and government colleges: a cross-sectional survey

Background: General health and oral health are interconnected, with oral health being a fundamental component. It is critical for life long human well-being. Oral health issues pose a significant concern for public health. Medical students should also have better knowledge of oral hygiene so that they can provide oral health education and guidance to their patients when requested. Many people seek medical care from their primary care provider for oral health problems. Therefore, doctors must have sufficient knowledge about oral health and play an important role in promoting oral health. This study aimed to assess the oral health knowledge of medical graduates from private and government colleges in Nellore, India. Methods: A Cross-sectional study using a pre-designed survey consisting of 25 questions with Likert scale options. The study included medical graduates from all private and government colleges. Questions about oral health issues and their relationship to overall health. Data was collected, compiled, and analyzed using the chi-square test. Results: Compared to government medical college students, 83.8% of private college students believe that dental caries and periodontal diseases are plaque-mediated diseases. 90.3% of government medical college students agree with the statement "tobacco is only the risk factor for oral cancer" compared to private college students. Conclusions: Medical students lack awareness of oral health issues. Frequently, oral health concerns are neglected as they focus on classroom dynamics and students’ behavior.

Clinical, Radiographic, and Histological Changes in Enamel and Dentin, According to Caries Care International™ Evaluation, In Permanent Posterior Teeth: An Observational Study / Cambios Clínicos, Radiográficos e Histológicos en Esmalte y Dentina, Según Evaluación de Caries Care International™, en Dientes Posteriores Permanentes: Un Estudio Observacional

SUMMARY: CariesCare International ™ practical guide is a tool for the comprehensive assessment and treatment of caries that synthesizes clinical and radiographic diagnosis and risk factors, classifying the severity, progression, and activity of lesions. The objective of this study was to analyze the validity and prediction characteristics of the proposed dental caries classification in the CariesCare International ™ practical guide as a reference through clinical and radiographic evaluation versus histological evaluation. Ninety-seven permanent posterior teeth were evaluated, and clinical and radiographic diagnoses were determined according to parameters defined in the CariesCare International™ guide as a reference. Subsequently, histological evaluation was performed to compare each stage of dental caries progression, and statistical analysis was applied. When comparing the validity and prediction values between radiographic and clinical diagnoses in relation to histological evaluation, a low sensitivity and high specificity relationship was found. The sensitivity and specificity percentages between the clinical and radiographic methods show that the clinical method has a lower number of false negatives. Histological changes in dental tissue were evident from the earliest stages of lesions, even in those not related to the caries process, indicating that the dentist should be careful when deciding on a treatment plan and take into account all variables involved in the caries process, as proposed by the CariesCare International ™ guide.

La guía práctica CariesCare International™ es una herramienta para la evaluación y tratamiento integral de la caries que sintetiza el diagnóstico clínico y radiográfico y los factores de riesgo, clasificando la gravedad, progresión y actividad de las lesiones. El objetivo de este estudio fue analizar la validez y características de predicción de la clasificación de caries dental propuesta en la guía práctica CariesCare International™ como referencia a través de la evaluación clínica y radiográfica versus la evaluación histológica. Se evaluaron noventa y siete dientes posteriores permanentes y se determinaron diagnósticos clínicos y radiográficos según parámetros definidos en la guía CariesCare International™ como referencia. Posteriormente se realizó una evaluación histológica para comparar cada etapa de progresión de la caries dental y se aplicó análisis estadístico. Al comparar los valores de validez y predicción entre los diagnósticos radiológicos y clínicos en relación con la evaluación histológica, se encontró una relación de baja sensibilidad y alta especificidad. Los porcentajes de sensibilidad y especificidad entre el método clínico y radiográfico muestran que el método clínico tiene un menor número de falsos negativos. Los cambios histológicos en el tejido dental fueron evidentes desde las primeras etapas de las lesiones, incluso en aquellas no relacionadas con el proceso de caries, lo que indica que el odontólogo debe tener cuidado al decidir un plan de tratamiento y tener en cuenta todas las variables involucradas en el proceso de caries, tal como propone la guía CariesCare International™.

Analysis of primary caregivers' knowledge concerning the cariogenic risk associated with the use of pediatric liquid medications / Análisis del conocimiento de los cuidadores principales sobre el riesgo cariogénico implicado en la ingesta de medicamentos líquidos pediátricos

Introduction: Pediatric liquid medications (PLM) are frequently administered to children, yet their usage may contribute to the onset of dental caries. Despite its prevalence, there is a notable scarcity of scientific research regarding caregivers' knowledge of this potential cariogenic risk. Objective: This study aims to assess the knowledge of the main caregivers of children aged 5 to 12 years concerning the cariogenic potential associated with the use of PLM. Materials and Methods: A cross-sectional analytical obser-vational study involving 152 primary caregivers of children aged 5 to 12 was conducted. Data were collected on caregivers' perceptions of the cariogenic risk associated with PLMs and their consumption habits. The study also assessed oral hygiene routines and evaluated the level of information provided by healthcare professionals. Results: Research findings indicated a significant lack of awa-reness among primary caregivers regarding the cariogenic risks of PLMs, with 78.95% being unaware of these risks and 47.37% unaware of the sugars present in such medications. Additionally, a high rate of PLM consumption was observed, with 63% of caregivers using them in the last year. The study underscored a notable absence of guidance from healthcare professionals, as 91.45% of the caregivers stated that they had not received instructions on tooth brushing after the administration of the PLM. Conclusions: The study highlights a significant lack of awa-reness among primary caregivers regarding the cariogenic risks associated with the ingestion of pediatric liquid medications. This deficit in information and preventive measures presents a substantial obstacle to children's oral health. To address this issue, it is crucial for healthcare professionals to offer comprehensive guidance and promote preventive measures.

Introducción: La administración de medicamentos líquidos pediátricos (MLP) es una práctica común en la población infantil y puede estar vinculada al desarrollo de lesiones de caries dental. Sin embargo, la evidencia científica que aborda el conocimiento de los cuidadores acerca de este riesgo cariogénico es escasa. Objetivo: Este estudio busca determinar el conocimiento de los cuidadores principales de niños de 5 a 12 años sobre el potencial cariogénico asociado al consumo de MLP. Materiales y Métodos: Se llevó a cabo un estudio observacional analítico transversal que incluyó a 152 cuidadores principales de niños en el rango de edad de 5 a 12 años. Se recopiló información sobre la percepción de los cuidadores acerca del riesgo cariogénico de los MLP, así como sobre sus patrones de consumo. Además, se registraron las prácticas de higiene oral y se evaluó el nivel de información proporcionado por los profesionales de la salud. Resultado: Los hallazgos de la investigación revelaron que un 78,95% de los cuidadores principales desconocen el riesgo cariogénico asociado al consumo de medicamentos líquidos pediátricos (MLP), y un 47,37% de ellos no eran conscientes de la presencia de azúcares en dichos medicamentos. Además, se observó un elevado índice de consumo de MLP, con un 63% de los cuidadores que los utilizaron en el último año. Se destacó la falta de orientaciones por parte de los profesionales de la salud, ya que, un 91,45% de los tutores afirmaron no haber recibido instrucciones sobre el cepillado dental posterior a la administración de los MLP. Conclusión: Este estudio evidencia un relevante porcentaje de desconocimiento entre los cuidadores principales acerca del riesgo cariogénico asociado a la ingesta de medicamentos líquidos pediátricos. La falta de información y medidas preventivas constituye un desafío significativo para la salud oral de los niños. Es imperativo que los profesionales de la salud proporcionen información detallada y fomenten prácticas de prevención.

Introducción: La caries es una de las enfermedades crónicas que más afecta a la humanidad, los niños son un grupo de alto riesgo de presentarla. La Calidad de Vida Relacionada con Salud Oral (CVRSO) se refiere a la percepción de las condiciones bucales de uno mismo y la manera en que los factores afectados impactan el bienestar y desempeño en las actividades diarias, el desarrollo de indicadores de esta se ve limitado por el nivel cognitivo de los niños, lo que genera el P-CPQ para determinar la percepción parental. Objetivo: determinar la percepción parental de la calidad de vida relacionada con la salud bucal de los niños de 6 a 10 años. Materiales y Métodos: se realizó un estudio observacional descriptivo con componente analítico. Se llevó a cabo una encuesta a 98 padres, el P-CPQ modificado que consta de 23 preguntas que abarcan las subescalas de síntomas orales, limitaciones funcionales, bienestar emocional y bienestar social. Resultados: Relacionando los resultados del cuestionario con la presencia de caries en dientes permanentes se reportó el aumento de caries con la edad; el sexo femenino predominó entre los participantes con caries siendo el 63,8%. La puntuación media fue de 13,6 (DE=13,1). Se presentó una asociación estadísticamente significativa entre la percepción parental de CVRSO de los niños y la presencia de caries dental en dientes permanentes (p=0,004). Conclusiones: Se concluyó que la presencia de caries en dientes permanentes en niños de 6 a 10 años puede disminuir significativamente la CVRSO en las dimensiones de síntomas orales, limitaciones funcionales y bienestar social.

Introduction: Caries is one of the chronic diseases that most affects humanity; children are a high-risk group for developing it. Oral Health Related Quality of Life (OHRQL) refers to the perception of one's own oral conditions and the way in which the affected factors impact well-being and performance in daily activities. The development of indicators of this is limited by the cognitive level of the children, which led to the P-CPQ to determine parental perception. Objective: to determine the parental perception of the quality of life related to the oral health of children from 6 to 10 years old. Materials and Methods: This was a descriptive and observational study with an analytical component. A survey of 98 parents was conducted, using the modified P-CPQ which consists of 23 questions covering the subscales of oral symptoms, functional limitations, emotional well-being, and social well-being. Results: Relating the results of the questionnaire with the presence of cavities in permanent teeth, an increase in cavities with age was reported; the female sex predominated among the participants with cavities, being 63.8%. The mean score was 13.6 (SD=13.1). There was a statistically significant association between parental perception of children's OHRQL and the presence of dental caries in permanent teeth (p=0.004). Conclusions: The presence of caries in permanent teeth in children aged 6 to 10 years can significantly reduce OHRQLin the dimensions of oral symptoms, functional limitations and social well-being.

Effect of lacteal products containing probiotic in the progression of tooth decay around orthodontic brackets

Objective: To evaluate the progression of caries around orthodontic brackets after the enamel has been exposed to lacteal products containing probiotics. Methods: Orthodontic brackets were bonded to the enamel surfaces. The test specimens were randomly divided into six groups: G1-negative control; G2-positive control, exposed to culture environment only (without microorganisms); G3-exposed to the cariogenic environment and the fermented cow's milk without probiotic; G4-exposed to the cariogenic environment and fermented cow's milk with probiotic; G5-exposed to the cariogenic environment and yogurt without probiotic; and G6-exposed to the cariogenic environment and yogurt with probiotic. The groups were placed in brain heart infusion medium, supplemented with 2% sucrose and with 1x106 cells/ml of Streptococcus mutans and Streptococcus salivarius (ATCC). The Shapiro-Wilk, Levene, Student t, Kruskal-Wallis, and Mann-Whitney tests were used. Results: all groups exposed to the ATCC strains showed lower final microhardness, compared to the negative control (p0.05). Conclusions: Lacteal products are not able to prevent the progression of caries around orthodontic brackets.

El objetivo del artículo es reportar el desempeño clínico en el control y disminución de la placa bacteriana en pacientes adolescentes mediante un gel y barniz con partículas S-PRG. Se realizaron tratamientos con materiales bioactivos con tecnología GIOMER en 2 pacientes. En el primer caso se realizó una profilaxis con Pro Care Gel (S-PRG) en un paciente de 15 años con problemas neuromotores para eliminar la placa y posteriormente, se aplicó un barniz con partículas de S-PRG para prevenir la formación de biofilm. En el segundo caso, un adolescente de 15 años normoreactivo con inflamación gingival recibió el tratamiento profilaxis con PRG Pro Care Gel.Se observó una disminución de placa bacteriana tras la profilaxis con el gel Pro Care y la aplicación del barniz en el primer caso. Además, existió una baja incidencia de biofilm incluso después de 11 meses de la aplicación del barniz. En el segundo caso, a las 2 horas de aplicación, se observó una disminución total de la placa. Clínicamente se observó el bueno desempeño clínico de los materiales con partículas de S-PRG, como lo demuestra la literatura científica en cuanto a la reducción de la formación de placa bacteriana en las estructuras dentarias, la desinflamación gingival, proporciona bienestar a los pacientes y restaura la salud bucal de forma menos invasiva.

The objective of the article is to report the clinical performance in the control and reduction of bacterial plaque in adolescent patients using a gel and varnish with S-PRG particles. Treatments with bioactive materials with GIOMER technology were performed in two patients. In the first case, prophylaxis was performed with Pro Care Gel (S-PRG) in a 15-year-old patient with neuromotor problems to eliminate plaque and subsequently, a varnish with S-PRG particles was applied to prevent biofilm formation. In the second case, a normal 15-year-old adolescent with gingival inflammation received prophylaxis treatment with PRG Pro Care Gel. A decrease in bacterial plaque was observed after prophylaxis with the Pro Care gel and the application of the varnish in the first case. Furthermore, there was a low incidence of biofilm even after 11 months of varnish application. In the second case, after 2 hours of application, a total decrease in plaque was observed. The good clinical performance of materials with S-PRG particles was clinically perceived, as demonstrated by the scientific literature in terms of reducing the formation of bacterial plaque in dental structures, gingival disinflammation, providing well-being to patients and restoring oral health in a less invasive way.

Dental caries and fissure sealant prevalence in first permanent molars among school boys aged 9 to 12 in Riyadh city, Kingdom of Saudi Arabia

Background: Dental caries is a major global public health concern. This study assessed dental caries prevalence and the use of fissure sealants on first permanent molars among Saudi Arabian boys aged 9–12 attending elementary schools to establish effective caries prevention strategies. Methods: Cluster probability sampling was employed to select public and private male elementary schools from five distinct geographic regions in Riyadh city, KSA; 601 male students in the fourth grade (aged 9–10 years), fifth grade (aged 10–11 years), and sixth grade (aged 11–12 years) were included. Only the first permanent molars’ occlusal surfaces were evaluated. Data management was performed using Microsoft excel, statistical analyses were conducted using the statistical package for the social sciences (SPSS), and the chi-square test was utilized. Results: The outcome demonstrated that 67.7% (n=407 children) had decayed, missing, or filled first permanent molars, indicating the presence of caries, while 32.3% (n=194) had caries-free first permanent molars. Only 6.8% (n=41) of children had received fissure sealants. At the tooth level, 37.7% (n=906) of examined teeth had decayed, and 8.1% (n=194) had fillings. The utilization rate of fissure sealants remained low at 3.9% (n=93), with 50.4% (n=1211) of first permanent molars remaining intact. Conclusions: This cross-sectional study highlights a significant prevalence between caries and the limited utilization of fissure sealants on first permanent molars among Saudi Arabian boys, underscoring the urgent need for proactive preventative measures and educational initiatives.

A review on four medicinal plants in dentistry

Dental caries and periodontal problems still remain a global health care burden. In developing and underdeveloped countries, the unmet treatment needs of a large part of population is a challenge to the service providers. WHO believes that oral health is a right to everyone. The use of traditional medicine helps in achieving these goals to a large extent. Medicinal plants are a basis for conventional medicine and a substitute for them. Thus, it becomes a matter of importance to have a greater understanding of the pharmacologically active components of the herbal components and their various uses in dentistry. This article aims to understand the phytotherapeutic uses of four commonly used herbal plants, miswak, moringa, triphala and neem.

Conclusion: The literature investigated suggests a plausibility between dietary patterns such as high consumption of sugar in the diet in relation to the occurrence of dental caries in autistic individuals.

Progress of Pulpal Disease Treatment in Young Permanent Teeth / 华中科技大学学报(医学版)

Young permanent teeth are not fully developed due to their short eruption,characterized by a relatively large pulp cavity,high and pointed pulp horns,and open apical foramina.Due to caries,abnormal tooth development or trauma,the dental pulp may be damaged or infected,which may lead to pulp necrosis and directly affect the normal tooth root formation.Therefore,the treatment of dental pulp disease in young permanent teeth poses a huge clinical challenge.The goal of clinical treatment is to promote continued root development of the affected tooth,thicken the root canal walls,and close the api-cal foramina.This article reviews the treatment options for reversible and irreversible pulpitis caused by pulp exposure,aiming to provide a reference for the treatment of pulp lesions in young permanent teeth,focusing on preserving healthy pulp and pro-moting pulp repair and regeneration.

Study on the current status of dental caries in preschool children in Chongming District， Shanghai / 上海预防医学

ObjectiveTo investigate the prevalence of dental caries among preschool children in Chongming District， Shanghai， and to analyze the related factors influencing dental caries in preschool children in Chongming District， in order to provide references and suggestions for the prevention of dental caries in preschool children in Chongming District. MethodsFrom January to April 2022， 939 preschool children from 5 kindergartens in Chongming District of Shanghai were selected as the research objects through random cluster sampling. The dental caries prevalence rate and related risk factors of dental caries in preschool children were studied through oral examinations and questionnaire surveys. ResultsThe prevalence rate of dental caries among the 939 preschool children was 45.69%. The prevalence of dental caries in preschool children was not related to gender but increased with age （P<0.001）. Risk factors for dental caries in children included consuming desserts between meals or before bedtime （OR=3.049， P<0.001）， consuming sugared milk （OR=2.389， P=0.027）， presence of dental caries in caregivers （OR=1.888， P<0.001）， age （OR=1.758， P<0.001）， regular consumption of certain beverages by children （OR=1.250， P=0.029）， and the frequency of snack consumption （OR=1.191， P=0.034）. ConclusionTo reduce the incidence of dental caries in preschool children， it is recommended that caregivers undergo oral health examinations and dental caries treatment to reduce the transmission of cariogenic bacteria. Additionally， reducing the frequency of children’s consumption of snacks， sugary drinks， and dairy products， and avoiding unhealthy eating habits such as consuming desserts before bedtime are advised. It is also important to educate children on proper toothbrushing methods to ensure the effectiveness of toothbrushing and to encourage them to develop good oral hygiene habits.

The Prevalence, Severity and Pattern of First Permanent Molars’ Dental Caries in Children Attending A Postgraduate Dental Hospital: A Retrospective Study

@#Introduction: First permanent molars (FPMs) erupt early and their anatomy and location leave them susceptible to dental caries. This study aimed to retrospectively determine the prevalence, severity and pattern of dental caries of FPMs and investigate their relationship if any with demographics and medical health status of the partcipants. Methods: This was a retrospective cross-sectional study. A sample of the digital case notes and radiographs of children aged 5 to 12 years who attended the only postgraduate dental hospital in Dubai were accessed. The recorded data included the children’s demographic variables and the carious status of each FPM as recorded in the notes on the initial assessment. Descriptive and statistical analyses were conducted (P<0.05). Results: A total of 2984 FPMs were obtained from the digital records of 774 children. Their mean age was 8.07 (±2.23) years and only those that met the inclusion criteria were included in the study. The prevalence of dental caries and mean Decayed Missing Filled Surfaces of FPMs, were 42% and 0.3 (±0.04), respectively. The most prevalent decayed surface was the occlusal (29.2%), followed by mesial, buccal, palatal/ lingual, distal surfaces (24.2 %; 6.6 %; 3.1 %; 2.3 %) respectively. Children with medical problems and/or special needs had a significantly higher level of caries in the buccal surfaces (12.3%) (P=0.042). Conclusion: Caries of FPMs in a sample of Dubai children studied was prevalent, especially in those with special healthcare needs, thus indicating a necessity for targeted prevention and treatment focused on these keystone teeth.

Analysis of prevalence of dental caries and associated factors among preschool children with disabilities in Bengbu / 中国学校卫生

Objective@#To understand the oral health status and associated factors of preschool children with disabilities in Bengbu City, so as to provide evidence for preventing dental caries in children with disabilities.@*Methods@#From September 2021 to March 2022, a total of 405 preschool children with disabilities from two rehabilitation institutions in Bengbu were randomly selected for oral health examination, questionnaire survey and physical examination. The caries prevalence rate among disabled children was analyzed. After grouping based on childrens BMI, the correlation between body mass index (BMI) and dental caries among children was explored. Multivariate binary Logistic regression analysis was employed to investigate the factors associated with dental caries occurrence in children.@*Results@#The prevalence of dental caries in preschool children with disabilities was 74.07%, with rates of 71.01% for boys and 77.27% for girls. There was a significant difference in caries prevalence between boys and girls aged 5（66.67%，88.24%） (χ2=7.53, P<0.05). There were significant differences in the dmft index among different BMI groups (underweight: 240, normal weight: 606, overweight:30,obese:60,H=35.66,P<0.05). BMI was negatively correlated with dmft（r=-0.50，P＜0.01）. Frequent tooth brushing (2-3 times daily), the use of fluoride toothpaste, limited intake of sugary foods (< 2 times/d) in the past six months, and exclusively breastfeeding within first six months were negatively correlated with the occurrence of dental caries in disabled children (OR=0.09，0.41，0.24, P＜0.05). Sleep forward to eat，parental education level of junior high school or lower, and parental education of vocational school or high school were positively correlated with dental caries (OR=3.18，5.95，3.99，66.95，7.75，P＜0.05).@*Conclusions@#The caries prevalence rate of disabled children in Bengbu City is high and is influenced by multiple factors. It is time to strengthen the oral health training for parents and teachers in educational institutions, pay attention to childrens oral health care, and help disabled children improve their quality of life.

Population heterogeneity analysis of caries prevention service preferences among children in Anhui Province / 中国学校卫生

Objective@#To determine the heterogeneity for caries prevention service preferences among children in Anhui Province, so as to provide reference for the promotion and popularization of caries prevention services for school age children.@*Methods@#Based on a discrete selection experiment, a face to face questionnaire survey was administered using a multi stage sampling method among 785 parents with children 3-12 years of age who were hospitalized in the stomatology clinics of 7 prefectures and cities in Anhui Province from October 2021 to October 2022. A mixed Logit model was used to evaluate caries prevention service preferences for children.@*Results@#Four discrete choice experiment attributes included in the study were statistically significant for choice preference ( P <0.05). Compared with the control group, parents with a high school education or above preferred caries prevention services with 70%-<80% preventive effectiveness, 2-<5 and <2 km from the service point, and a high service cost ( β =0.38, 1.66, 1.64, 0.00); female parents preferred preventive services with 70%-<80% preventive effectiveness and a high service cost ( β =0.35, 0.01 ); parents of children <7 years of age preferred services with 70%-<80% preventive effectiveness ( β =0.75); parents of children with oral health preferred preventive services during winter and summer vacations ( β =-0.28); parents of children with caries preferred preventive services with a high cost per denticle ( β =0.00)( P <0.05).@*Conclusions@#Parents with different education levels, gender, child age, and oral health status have heterogeneity in dental caries prevention service preferences. The provision of targeted and precise services can improve the participation and coverage of caries prevention services for school age children.
