Exploring the Threefold Viewpoint on Children's Oral Health in a Cross-Sectional Study

Oral health is situated within the framework of the global health agenda, addressing facets pertaining to well-being and quality of life. The research is based on the need to address variables at the community level to improve schoolchildren's oral health and promote healthy behaviors and aims to carry out an in-depth analysis from the perspective of the factors that influence children's oral health. Step 1, designed by the World Health Organization, was utilized. An easy-to-use web interface was created for data collection. The statistical analysis consisted of using multinomial and binominal logistic regression models. The level of education of the adult has a high probability of influencing the consumption of unhealthy or healthy foods, it has a significant probability of exerting influence on social or medical problems and a correlation was found between the level of academic education and the pattern of dental visits. The development of health-promoting behaviors begins in childhood and involves parents, who have an essential role in the education of their children. Oral health promotion programs in schools need to target the child-adult-teacher-dentist relationships. Taking into consideration the aforementioned, a threefold viewpoint is necessary for the development of a national program aimed at promoting the oral health of schoolchildren in Romania.

Knowledge and Attitudes of Parents about Oral Health in the Primary Dentition Stage in a Peruvian High Andean City

Children's oral health depends on parents' knowledge and attitudes. The primary dentition stage, in particular, plays a crucial role in the comprehensive development of children. Therefore, the objective was to evaluate parents' knowledge and attitudes about oral health in the primary dentition stage in Chachapoyas (Amazonas, NW Peru). A questionnaire was administered to 409 parents from 15 educational institutions, and the data were analyzed using multinomial logistic regression. Among the surveyed parents, 75.3% could identify at least one habit harmful to their children's teeth (such as excessive sugar consumption) and one of its effects (such as dental caries). Additionally, 77.5% reported that their children presented some dental problem, more frequent in the peripheral areas than in the city's center. Gender (odd ratio, OR = 0.484; p = 0.037), educational level (OR = 2.144; p = 0.043), and type of health insurance (OR = 2.627; p = 0.044) of the parents influenced awareness of taking care of their children's primary dental health. The geographic location of the school (1.729 < OR < 2.079; p ≤ 0.011) and family income (OR = 3.504; p = 0.028) influenced parents' identification of the different harmful effects of children's habits. Factors such as low socioeconomic status and never taking the child to the dentist increased the risk of dental problems (p < 0.05). It is suggested that peripheral areas, like rural areas, lack the same oral health programs and access to treatment as central urban areas, leading to disparities in parental knowledge and attitudes.

A STEPwise Approach for Oral Hygiene Behavior of Schoolchildren in Romania

This research analyzes the dental hygiene habits of schoolchildren from parents' perspectives, using the STEPS approach recommended by the World Health Organization. The key points of oral health care in children include the role of the family in encouraging and maintaining proper oral hygiene practices. This study aimed to assess the oral hygiene practices of schoolchildren with on-site dentists in Romania. Additionally, it sought to establish correlations between these behaviors and the educational levels of the adults with whom they live with. The participants were selected from the zero grade to the eighth grade, totaling 3843students. Statistical analysis involved the application of Fisher's Exact Test and Z-tests with Bonferroni correction. Multinominal and binominal logistic regression models were employed to predict the impact of parents' education on children's oral health status and behavior. The oral health status of children evaluated by parents as poor was more frequent in children whose parents had a primary or gymnasium education (p < 0.001). Female adults with a university education evaluated the gum health of their children as very good to a much greater extent (41.7%, p < 0.001). Regarding the use of auxiliary means, the majority of parents with a university education mentioned that their children use dental floss (26.4% females/27.4% males) (p < 0.001), compared to those with primary education, where the percentage was only (1.2% males/3.5% females) (p < 0.001). The results of this study highlight that the education level of the adults with whom the children live with influences the perception of the teeth and gums health status, the frequency of oral hygiene, the use of fluoride toothpaste, and auxiliary brushing aids.

A Modified Tongue Crib Appliance for Correction of Tongue Thrusting

Digit sucking and tongue thrusting are parafunctional habits that are commonly observed and are recognized as major etiological factors in the development of dental malocclusion. Treatment for these oral habits typically involves removal of the etiology, retraining exercises, and use of mechanical restraining appliances. A 13-year-old male patient reported a complaint of forwardly placed upper front teeth. The extraoral examination of the patient showed a convex profile, good facial symmetry, acute nasolabial angle, incompetent lips at rest, and a shallow mentolabial sulcus. Intraoral examination showed class I molar and canine relations on either side, a mild open bite tendency, a midline diastema, proclined upper and lower anteriors, an increased overjet, and tongue thrusting habit. A modification to the tongue crib was made by adding an acrylic bead in the center of the crib. The patient was trained to roll the bead posteriorly with the aim of retraining the tongue to posture away from the front teeth. Harmful forces of the tongue can result in excessive posterior teeth eruption, open bite, and increased overjet. Duration of appliance wear and type of appliance used are important considerations in treating patients with tongue thrust or open bite. A modified tongue crib was used for six months resulting in significant improvement in maxillary anterior dentition position, lip competence, arch forms, overbite, and midline diastema closure. A tongue crib is a useful tool for addressing tongue thrusting and digit-sucking behaviors by retraining the related muscles, providing physical restraint, and serving as a reminder to break the habit. It can be used in conjunction with a fixed appliance to improve its effectiveness.

Malocclusions in Pediatric Patients with Asthma: A Case-Control Study

Asthma is a public health problem that has been widely described, but little has been reported about its effects on dental occlusions. The aim of this study was to compare the alterations of normal occlusions in asthmatic children and those without the disease. The study included 186 patients between 5 and 12 years old, divided into two groups. The first group included patients with a previous diagnosis of asthma given by a specialist, which was confirmed by using the International Study of Asthma and Allergies in Childhood questionnaire. The second group included patients without the disease. All patients underwent a clinical examination to determine the presence of occlusion alterations in the sagittal, transverse, and vertical planes. Subsequently, chi-squared tests were performed to compare the variables between the groups. A significant association was found between asthma and the variables studied here: alterations in the sagittal plane (chi2 = 7.839, p = 0.005), alterations in the vertical plane (chi2 = 13.563, p < 0.001), alterations in the transverse plane (Fisher’s F p < 0.001), and oral habits (chi2 = 55.811, p < 0.001). The results suggest that asthmatic patients are more likely to develop malocclusions, especially anterior open bite and posterior crossbite. These conditions are typically related to mouth breathing, which is common in asthmatic patients.

Oral Function and Eating Habit Problems in People with Down Syndrome

BACKGROUND

Down syndrome (DS) is a genetic disorder in which there is an increased risk of developing clinical comorbidities that require regular attention: health problems, alterations in maxillomandibular development, chewing and swallowing problems, as well as dietary habits that may influence diet and nutritional status. This study will analyze the frequency of occurrence of these factors with increasing age in this population.

METHODS

A descriptive cross-sectional study was conducted with 18 participants aged 30-45 years. The condition of orofacial structures, chewing and swallowing function and oral and eating habits were assessed to observe the frequency of occurrence of these problems with increasing age.

RESULTS

A high frequency of digestive problems was observed. There was also a presence of problems in the introduction of new tastes and consistencies. In addition, unilateral chewing was reported in 100% of the participants, severe anatomical dysfunction of the mandible/maxilla and high hypotonicity reflected in tongue movements.

CONCLUSIONS

it is necessary to educate, through specific intervention protocols, the younger generations with DS, as well as their environment, as harmful habits are developed in childhood and consolidated throughout life.

Oral Habits in Children With Orofacial Clefts: A Comparative Study

BACKGROUND AND AIM

Children with cleft lip and palate present with a wide range of dental and occlusal anomalies as a result of the cleft defect. These patients also present with oral habits which may affect their quality of life. The aim of this study was to compare the prevalence of oral habits in these children, with children without orofacial clefts.

METHODOLOGY

This was a cross-sectional comparative study comparing children with repaired cleft lip and/or palate aged 3 to 12 years, with children without orofacial clefts. Ethical approval for the study was obtained from the institutional review boards of both centers. Data collection was via interviewer administered questionnaires given to the parents/guardians of the children in each group. Data analysis was carried out using SPSS version 23. The level of significance was set at P < .05.

RESULTS

A total of 107 respondents participated in the study, comprising 53 children with repaired cleft lip and/or palate 54 children without orofacial clefts. The mean age for the children with Cleft lip and/or palate/ was 6.81 (standard deviation [SD] 1.898) years, while that for the control group was 7.78 (SD 1.68) years. Two oral habits recorded a significantly higher prevalence (P < .05) in the children with repaired clefts as compared to controls and these were lip sucking and bruxism. No significant difference in prevalence was recorded for all the other oral habits surveyed.

CONCLUSION

A significantly higher prevalence (P < .05) was observed in lip sucking and bruxism among children with cleft lip and palate, as compared to the children without orofacial clefts.

Genes and SNPs in the pathway of immune response and caries risk: a systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to pool the data on Single Nucleotide Polymorphisms (SNPs) in immune response genes associated with dental caries. Nineteen studies were included in the review and 18 in the meta-analysis. Twenty-two SNPs were evaluated, which are linked to six different genes (MBL2, LFT, MASP2, DEFB1, FCN2 and MUC5B). Most SNPs (81.8%) are related to the possible functional impact on protein coding. The MBL2 gene was associated with caries experience in the analysis of the homozygote (OR = 2.12 CI95%[1.12-3.99]) and heterozygote (OR = 2.22 CI95%[1.44-3.44]) genotypes. The MUC5B gene was associated according to an analysis of the heterozygous genotype (OR = 1.83 CI95%[1.08-3.09]). Thus, SNPs related to immune response genes are linked to the phenotype of caries experience. Although the meta-analysis showed that the genes MBL2 and MUC5B were associated with caries, these results should be interpreted with caution due to the quality of the evidence.

Tooth Malformations, DMFT Index, Speech Impairment and Oral Habits in Patients with Fetal Alcohol Syndrome

Background: Fetal alcohol spectrum disorder (FASD) is a developmental disorder with severe negative lifetime consequences. Although knowledge about the harmfulness of alcohol consumption during pregnancy has spread, the prevalence of fetal alcohol spectrum disorder is very high. Our study aims at identifying fetal alcohol syndrome (FAS)-associated dental anomalies or habits, which need early attention. Methods: Sixty children (30 FAS; 30 controls) were examined prospectively. Swallowing pattern, oral habits, breastfeeding, speech therapy, ergotherapy, physiotherapy, exfoliation of teeth, DMFT (decayed, missing, filled teeth) index, modified DDE (developmental defects of enamel) index and otitis media were recorded. Results: Swallowing pattern, exfoliation of teeth, and otitis media were not significantly different. Significant differences could be found concerning mouthbreathing (p = 0.007), oral habits (p = 0.047), age at termination of habits (p = 0.009), speech treatment (p = 0.002), ergotherapy, physiotherapy, and breastfeeding (p ≤ 0.001). DMFT (p ≤ 0.001) and modified DDE (p = 0.001) index showed significantly higher values for children with fetal alcohol syndrome. Conclusions: Children with fetal alcohol syndrome have a higher need for early developmental promotion such as speech treatment, ergotherapy, and physiotherapy. Mouthbreathing, habits, and lack of breastfeeding may result in orthodontic treatment needs. High DMFT and modified DDE indexes hint at a higher treatment and prevention need in dentistry.

Presence of oral habits and their association with the trait of anxiety in pediatric patients with possible sleep bruxism

BACKGROUND

Bruxism is a repetitive masticatory muscle activity with a multifactorial etiology , that can be associated to emotional factors.

AIM

The aim of the study is to identify the presence of oral habits (OHs) and their association with the trait of anxiety (State-Trait Anxiety Inventory for Children [STAI-C]) in pediatric patients with possible sleep bruxism (PSB).

METHODS

Children between 3 and 12 years of age with PSB reported by their parents with complete deciduous or mixed dentition were included in the present study. Sociodemographic data (SD) as well as those on OHs such as only natural (ON), artificial breastfeeding (OA) or both (NA), finger sucking (FS), pacifier use (PC), and biting nails (BN) or objects (OB) were obtained through an interview with the parents/guardians answered the Brazilian version of the STAI-C questionnaire.

STATISTICAL ANALYSIS USED

SD and OH as well as STAI-C findings were descriptively evaluated, while the associations between OH and STAI-C with PSB were evaluated using the Chi-square test (P < 0.05).

RESULTS

The final sample was 52 children (6.62 ± 1.8 years). Of these, 51.9% were males, 82.7% reported not living in social risk areas, and 21.2% were only children. Considering the OH, patients participated in ON (26.9%), OA (9.6%), and both (63.5%); 13.5% had an FS habit and 46.2% had related PC use; and 80.8% were reported to have OB biting behaviors, while 53.8% participated in BN. The STAI-C was present in 25 (48.1%) patients with PSB and was not associated with the presence of OH.

CONCLUSION

There is no association between STAI-C and OH in pediatric patients with PSB.

Awake and Sleep Bruxism Among Israeli Adolescents

Introduction: Sleep and awake bruxism are potential risk factors for oral hard tissue damage, failure of dental restorations and/or temporomandibular disorders. Identifying the determinants of sleep and awake bruxism among adolescents will enable development of preventive interventions for those at risk.

Objectives: To determine emotional, behavioral and physiological associations of sleep and awake bruxism among Israeli adolescents.

Methods: Two thousand nine hundred ninety-three Israeli high school students, from five different high schools in Israel, were approached in the classroom and requested to complete online questionnaires on sleep and awake bruxism, emotional aspects, smoking, alcohol consumption, oral habits, facial pain, and masticatory disturbances. The final study sample concerning awake and sleep bruxism included 2,347 participants.

Results: 1,019 (43.4%) participants reported not experiencing any form of bruxism (neither sleep nor awake), 809 (34.5%) reported awake bruxism, 348 (14.8%) reported sleep bruxism and 171 (7.3%) reported both sleep and awake bruxism. Multivariate analyses (Generalized Linear Model with a binary logistic dependent variable) showed that one of the prominent variables affecting the occurrence of sleep bruxism was anxiety (mild, moderate and severe anxiety, Odds Ratios (OR) of 1.38, 2.08, and 2.35, respectively). Other variables associated with sleep bruxism were stress (each point in the stress scale increased the risk of SB by 3.2%), temporomandibular symptoms (OR = 2.17) and chewing difficulties (OR = 2.35). Neck pain showed a negative association (OR = 0.086). Multivariate analyses for awake bruxism showed an effect of moderate anxiety (OR = 1.6). Other variables associated with awake bruxism were stress (each point in stress scale increased the risk of AB by 3.3%), high and low levels of facial pain (OR = 2.94 and 1.53, respectively), creaks (OR = 1.85) and oral habits (OR = 1.36). Sleep bruxism was found to be a predictor for awake bruxism, and vice versa. In both cases ORs were 8.14.

Conclusions: Among adolescents, sleep and awake bruxism are associated with emotional aspects as well as with facial pain symptoms and/or masticatory system disturbances. Awareness is recommended to decrease potential risks to teeth, dental restorations, and the masticatory system.

Evaluation of Crossbites in Relation with Dental Arch Widths, Occlusion Type, Nutritive and Non-nutritive Sucking Habits and Respiratory Factors in the Early Mixed Dentition

PURPOSE

The purpose of this study was to analyse the connection between dental arch widths, malocclusion type, nutritive sucking habits and non-nutritive sucking habits, and respiratory factors with the presence of crossbites (CB) in the early mixed dentition.

MATERIALS AND METHODS

Data were collected from 72 children with and without CB. A questionnaire was applied to parents/carers to obtain information about nutritive and non-nutritive sucking habits. The posterior and anterior crossbites were diagnosed in a centric relationship. Dental arch widths were measured directly from the models by two calibrated examiners. The data were analysed statistically using chi-square and Fisher's exact tests.

RESULTS

The incidence of Class III malocclusion and the presence of ear, nose and throat problems in the study group were significantly higher than in the control subjects (p = 0.01, p = 0.047). The mean breastfeeding duration for children in the CB group was found significantly shorter than in the control subjects (p = 0.043). The number of children with mouth breathing in sleep was significantly higher in the CB group than the control subjects (p = 0.046). The children with CB demonstrated a statistically significant increase in mandibular intercanine width (ICW) than the control group (p = 0.044).

CONCLUSION

The results demonstrated that an insufficient duration of breastfeeding, mouth breathing, ear-nose-throat problems and Class III malocclusion were associated with the presence of CB in the early mixed dentition.

Evaluation of knowledge and attitude of parents about the importance of maintaining primary dentition - A cross-sectional study

Introduction:

Dental caries is very common in primary dentition because of improper oral hygiene and increased intake of sucrose. Grossly decayed primary teeth require extraction. The space created by extracted teeth should be replaced by primary dentition to avoid migration of adjacent teeth into the space and to prevent the eruption of permanent tooth. Different appliances are used to maintain the space post extraction of the primary tooth to preserve the space for the eruption of the permanent tooth in a sequential manner.

Aim:

Evaluate the attitude and knowledge of parents toward the importance of maintaining primary dentition in their children.

Methods:

A survey was conducted among randomly selected 100 parents having children between the ages of 2 and 16 years from the general population of Chennai, India. A questionnaire was created was distributed. The data were later collected and statistical analysis was performed.

Results:

Hundred percent awareness was seen among parents regarding maintenance of oral hygiene in children. Only 65% parents reported visiting dentists only when the child complains of pain. Eighty-nine percent of the parents were aware of the harmful effects of thumb sucking habits. However, only a minimum percent parents thought that treating primary teeth was not very important as it would shed off.

Conclusion:

Even though parents were aware that primary teeth have to be managed properly, they were not aware of the various treatment modalities available for treating spaces after extraction of primary teeth and caries management. An increase in the knowledge will encourage parents to provide better oral health to their children.

Knowledge and attitude of pediatricians toward digit sucking habit in children

BACKGROUND

Finger sucking and prolonged dummy sucking are the most prevalent oral habits among infants, toddlers, and children. Pediatricians are more likely to see infants and children much earlier than dentists. Thus, it is essential for these specialists to be aware of the harmful nature of digit sucking habit and its associated complications.

AIMS AND OBJECTIVES

The present study was designed to evaluate the knowledge and attitude among pediatricians about digit sucking habit in children.

METHODOLOGY

The survey was carried out using a self-administered questionnaire which was delivered to the study subjects by hand or by mail. The returned questionnaires from the pediatricians were statistically analyzed using descriptive statistics (percentage).

RESULTS

This study showed that many respondents were unaware that oral habits could be responsible for malocclusion. A high percentage of respondents preferred not to examine oral features in digit sucking child. Among the etiological factor that may contribute to digit sucking habit in a child, most of the respondents expressed that habitual, psychological and inadequate parental care are possible causes. Most of the participants answered that parental and child counseling is essential to stop the habit. Most of the respondents did not refer the digit sucking child to the dentist for the better management of associated malocclusion.

CONCLUSION

Knowledge and attitude among pediatricians about digit sucking habit in children were found to be unsatisfactory. Continuing dental education programs and symposiums can be conducted for pediatricians to enhance their knowledge about pernicious oral habits.

Three-dimensional ultrasound evaluation of tongue posture and its impact on articulation disorders in preschool children with anterior open bite

Background Tongue posture plays an important role in the etiology of anterior open bite (AOB) and articulation disorders, and is crucial for AOB treatment planning and posttreatment stability. Clinical assessment of tongue posture in children is unreliable due to anatomical limitations. The aim of the study was to present functional diagnostics using three-dimensional ultrasound (3DUS) assessment of resting tongue posture in comparison to clinical assessment, and the associations between the improper tongue posture, otorhinolaryngological characteristics, and articulation disorders in preschool children with AOB. Patients and methods A cross-sectional study included 446 children, aged 3-7 years, 236 boys and 210 girls, examined by an orthodontist to detect the prevalence of AOB. The AOB was present in 32 children. The control group consisted of 43 children randomly selected from the participants with normocclusion. An orthodontist, an ear, nose and throat (ENT) specialist and a speech therapist assessed orofacial and ENT conditions, oral habits, and articulation disorders in the AOB group and control group. Tongue posture was also assessed by an experienced radiologist, using 3DUS. The 3DUS assessment of tongue posture was compared to the clinical assessment of orthodontist and ENT specialist. Results The prevalence of AOB was 7.2%. The AOB group and the control group significantly differed regarding improper tongue posture (p < 0.001), and articulation disorders (p < 0.001). In children without articulation disorders from both groups, the improper tongue posture occured less frequently than in children with articulation disorders (p < 0.001). After age adjustment, a statistical regression model showed that the children with the improper tongue posture had higher odds ratios for the presence of AOB (OR 14.63; p < 0.001) than the others. When articulation disorders were included in the model, these odds ratios for the AOB became insignificant (p = 0.177). There was a strong association between the improper tongue posture and articulation disorders (p = 0.002). The 3DUS detected the highest number of children with improper resting tongue posture, though there was no significant difference between the 3DUS and clinical assessments done by orthodontist and ENT specialist. Conclusions The 3DUS has proved to be an objective, non-invasive, radiation free method for the assessment of tongue posture and could become an important tool in functional diagnostics and early rehabilitation in preschool children with speech irregularities and irregular tongue posture and malocclusion in order to enable optimal conditions for articulation development.

Lack of association between LTF gene polymorphisms and different caries status in primary dentition

OBJECTIVE

Dental caries is related to cariogenic bacteria, salivary components, oral hygiene and host susceptibility. Lactoferrin is an important antimicrobial glycoprotein in saliva; however, the role of the LTF gene in caries susceptibility is unclear. We investigated the association between LTF polymorphisms and the severity of caries.

DESIGN

Our study included 910 healthy paediatric subjects (aged 24-48 months) categorised into three groups: 403 with no caries or white-spot lesions; 230 with moderate caries (8 ≤ dmft ≤ 12); and 277 with severe caries (13 ≤ dmft ≤ 20). Information regarding the subjects' oral habits was gathered using questionnaires. The LTF rs1126477 and rs1126478 polymorphism alleles were genotyped by Sanger sequencing.

RESULTS

The three groups showed no significant differences in LTF polymorphisms alleles, genotypes or haplotypes distribution. Multifactor dimensionality reduction analysis showed that the interactions between breastfeeding for a duration >24 months, night feeding >24 months and high frequency of sweet food intake increased the risk of caries (p = 0.0014); however, we detected no interaction effect between the LTF polymorphisms and oral habits on caries susceptibility.

CONCLUSIONS

The LTF rs1126477 and rs1126478 polymorphisms showed no association with the different levels of caries risk in our Chinese paediatric cohort.

A Preliminary Investigation into the Dietary and Oral Practices Associated with Fractured Teeth and Prostheses in a Trinidadian Population

OBJECTIVES

This preliminary study seeks to determine the relationship between fractured teeth, restorations, prostheses, and specific dietary practices.

METHODOLOGY

Anonymous questionnaires were randomly distributed to a convenience sample of Trinidadian adults at various locations around the country, after gaining consent. Data were analyzed using the software; Statistical Package for the Social Sciences for significant associations between various types of food and broken teeth or prosthesis using odds ratios.

RESULTS

Three hundred questionnaires were completed. Seventy-five percent of the patients preferred crunchy or hard foods and 51% of the respondents liked crushing bones, mostly chicken bones. It was observed that respondents with a dietary preference for fried whole chana, split chana, crab, and sugarcane were significantly associated with broken dentures. Respondents eating whole chana also had a significant association with broken teeth and broken dentures. Associations were found between some dietary preferences, ethnicities, and age groups.

CONCLUSIONS

Significant associations between age, ethnicity, sex, and certain dietary practices and habits were found. There also appears to be a significant relationship between patients with fractured teeth, restorations, and prostheses with certain dietary preferences.

Oral habits, dental trauma, and occlusal characteristics among 4- to 12-year-old institutionalized orphan children in Riyadh, Saudi Arabia

The aim of this study was to assess the oral habit practices, dental trauma, and occlusal characteristics of 4- to 12-year-old orphans living in governmental orphanages in Riyadh. This cross-sectional study was conducted in three government orphanages and three ordinary schools. All 90 orphans, residing in the orphanage, were included. Ninety schoolchildren were selected to serve as the controls. Demographic data, oral habit history, and dental trauma history were obtained through a questionnaire. All children were examined to confirm the presence of signs of oral habits, dental trauma, and associated occlusal characteristics. Pearson chi-square was used for statistical analysis. Orphans were found to have more digit sucking and oral self-mutilation habits; however, the control children were found to have more nail biting habit. Nearly 21% of the orphans had dental trauma compared to 10% of the control group. About 70% of the dental trauma affected permanent teeth among orphans, whereas, 85% affected primary teeth in the control children. Dental trauma increased as the orphans got older; however, it decreased significantly as the control children got older. Orphans were found to have more cross-bite, increased over-jet, and open-bite. Digit sucking habit was positively associated with class II molar relation, presence of posterior cross-bite, and open-bite. Orphans had increased prevalence of digit sucking habit, self-mutilation, dental trauma, and malocclusion.

The impact of an educational pamphlet on the awareness of parents about 4‒6-year-old children's oral habits and dentofacial discrepancies

Background. This study aimed to evaluate whether the parents’ knowledge about the adverse effects of oral habits and dentoskeletal discrepancies would improve by an educational pamphlet.

Methods. A parallel-group randomized clinical trial was conducted on parents in kindergartens of Shiraz, Iran, 2013. The parents completed a designed questionnaire to determine the pre-intervention score. The study group received an educational pamphlet on the oral habits and dentoskeletal discrepancies, in contrast to the control group. Three weeks later, the parents in both groups took the questionnaire again (post-intervention score). The primary outcome was a change in the parents’ knowledge about oral habits and dentoskeletal discrepancies, which was measured by 13 questions of the questionnaire. Each correct answer was given a positive point and each incorrect answer a negative point. The total pre- and post-intervention scores were calculated by summing up the points and compared using Mann–Whitney U test.

Results. A total of 550 subjects were assessed for eligibility and 413 were randomized. Of the study group, 203 subjects (98.56%), and of the control group, 204 parents (98.54%) completed the questionnaire for the second time. The score of the study group in the "normal occlusion" section of the questionnaire had significantly improved (P < 0.001) and in the "oral habits" section the score of both groups had improved but in the study group the improvement was significantly higher (P < 0.001).

Conclusion. The educational pamphlet can be effective in increasing the level of parents’ knowledge about normal occlusion and complications of oral habits.

Differences in oral habit and lymphocyte subpopulation affect malignant transformation of patients with oral precancer

BACKGROUND/PURPOSE

In Taiwan, the combination of betel quid chewing, alcohol consumption, and smoking habits increases oral cancer risk by 123-fold compared to persons without these habits. Lymphocyte populations in patients may potentially affect the malignant transformation of oral precancer.

METHODS

A total of 28 patients with oral precancer from our previous cohort were enrolled in this study, and their personal information and oral habits were documented. Their lymphocyte populations (CD4+, CD8+, CD19+, and CD56+) and activation markers (CD25 and CD69) were determined by flow cytometry from 1999 to 2004. After follow up till December 2014, data of patients with/without malignant transformation were recorded, and the relation between oral habits and percentage of initial lymphocyte markers was evaluated using the Student t test and Fisher's exact test.

RESULTS

Ten precancer patients developed oral squamous cell carcinoma with a mean period of malignant transformation of 6.8 ± 2.1 years. Patients with malignant transformation had a mean age of 48.4 ± 5.0 years (n = 10), relatively more than that of patients without malignant transformation (41.6 ± 6.3 years, n = 18) (p < 0.05). An increase was noted in the population of peripheral blood mononuclear cells expressing CD4+CD69+, CD19+CD69+, and CD56+CD69+ (p < 0.05) in precancer patients with malignant transformation. Alcohol consumption showed an association with the malignant transformation of patients with precancer (p = 0.030), whereas betel quid and smoking showed little effect.

CONCLUSION

These results suggest that age, alcohol consumption, and early activation of T cells, B cells, and natural killer cells are crucial in the malignant transformation of oral precancer. Analysis of patient's lymphocyte populations may help predict the malignant transformation of oral precancer.

Deleterious oral habits in children with hearing impairment

Background and aims

Deleterious oral habits represent a serious public health issue. The information available about this problem in children with hearing impairment is insufficient. The purpose of this study was to investigate the prevalence of deleterious oral habits among children with hearing impairment and comparing results against children without hearing impairment.

Method

This epidemiological study was carried out in a sample size of 315 children. We used a random sampling technique that included 150 children with hearing impairment and 165 without hearing impairment. All subjects were submitted to a clinical examination. The parents/legal guardians were asked to complete a questionnaire regarding the deleterious habits of their children.

Results

The data collected indicated a higher prevalence of deleterious oral habits among children with hearing impairment: 53.3% as opposed to 40.6% among children without hearing impairment. There was a higher incidence of malocclusion in children with hearing impairment (79.3%) compared to children without hearing impairment (57%).

Conclusions

This study highlighted the need to establish protocols for preventive orthodontic treatment at an early age, in order to reduce the deleterious oral habits and prevent malocclusion. Dental institutions/clinicians need to implement oral care programs including proper oral education aiming to promote oral health.

A comparative evaluation of oral hygiene practices, oral health status, and behavior between graduate and post-graduate dentists of North India: An epidemiological survey

Objectives:

The present study was carried out to compare oral hygiene practices, oral health status and behavior of graduate and postgraduate dentists of North India.

Materials and Methods:

The study was carried out among 727 dentists (446 graduate i.e., Group A and 281 post graduate i.e., Group B) through an online questionnaire. The questionnaire covered oral hygiene regimen, adverse oral habits, information regarding dental visits and dental treatment.

Results:

Results showed less than adequate oral hygiene practices among both the groups with more so in the graduate group (P ≤ 0.05). Very few dentists in both the groups reported any adverse oral habit. A more positive (P ≤ 0.05) attitude towards regular dental check up and dental treatment was seen in post-graduate dentists when compared to graduates.

Conclusion:

Very few dentists in both the groups followed ideal dental hygiene regimen. Dentists are the role models for the society as far as oral health is concerned; hence they need to be more responsible and lay more stress on their daily regimen and improve the scenario.

Comparison of soft-tissue, dental, and skeletal characteristics in children with and without tongue thrusting habit

Background:

Tongue thrusting habit is a condition in which the tongue makes contact with any teeth anterior to the molars during swallowing. Abnormal positioning of tongue may result in dental and skeletal abnormalities.

Objective:

The aim of the present study was to study and compare soft-tissue, dental, and skeletal morphologic characteristics in children with and without tongue thrusting habit.

Materials and Methods:

A total of 21 children with tongue thrusting habit and 21 children without any habit between age 10 and 14 years were selected for the study. Various soft-issue, dental and cephalometric parameters were measured and compared statistically.

Results:

Significantly, higher number of children with tongue thrusting showed lip incompetency (86% vs. 14%), mouth-breathing habit (38% vs. none), hyperactive mentalis muscle activity (24% vs. none), Open-bite (52% vs. none) and lisping (86% vs. none) when compared to children without tongue thrust. Children with tongue thrust showed increased upper lip thickness and proclination of maxillary incisors No differences were found in angulation of mandibular incisors, inter-premolar or inter-molar widths and all the skeletal parameters studied.

Conclusions:

Tongue thrust seemed to affect some of the soft-tissue and dental characteristics causing lip incompetency, mouth-breathing habit, and hyperactive mentalis muscle activity, lisping, open-bite, and proclination of maxillary incisors; however, no significant skeletal changes were observed.

Behavioral determinants of brushing young children's teeth: implications for anticipatory guidance

PURPOSE

The purposes of this study were to identify parents' motivation, support, and barriers to twice daily tooth-brushing of infants and preschool-age children and to discover new approaches to encourage this important health behavior.

METHODS

Qualitative interviews were conducted with 44 rural parents about tooth-brushing habits and experiences.

RESULTS

Forty of 44 parents reported that they had begun to brush their child's teeth; 24 (55%) reported brushing twice a day or more. Parents who brushed twice a day, vs less often, were more likely to describe specific skills to overcome barriers; they expressed high self-efficacy and held high self-standards for brushing. Parents who brushed their children's teeth less than twice daily were more likely to: hold false beliefs about the benefits of twice daily tooth-brushing; report little normative pressure or social support for the behavior; have lower self-standards; describe more external constraints; and offer fewer ideas to overcome barriers.

CONCLUSIONS

The findings support an integrative framework in which barriers and support for parents' twice daily brushing of their young children's teeth are multiple and vary among individuals. Knowledge of behavioral determinants specific to individual parents could strengthen anticipatory guidance and recommendations about at-home oral hygiene of young children.

Mexican American mothers' initiation and understanding of home oral hygiene for young children

PURPOSE

To investigate caregiver beliefs and behaviors as key issues in the initiation of home oral hygiene routines. Oral hygiene helps reduce the prevalence of early childhood caries, which is disproportionately high among Mexican-American children.

METHODS

Interviews were conducted with a convenience sample of 48 Mexican-American mothers of young children in a low income, urban neighborhood. Interviews were digitally recorded, translated, transcribed, coded and analyzed using standard qualitative procedures.

RESULTS

The average age of tooth brushing initiation was 1.8 +/- 0.8 years; only a small proportion of parents (13%) initiated oral hygiene in accord with American Dental Association (ADA) recommendations. Mothers initiated 2 forms of oral hygiene: infant oral hygiene and regular tooth brushing. For the 48% of children who participated in infant oral hygiene, mothers were prompted by pediatrician and social service (WIC) professionals. For regular tooth brushing initiation, a set of maternal beliefs exist about when this oral hygiene practice becomes necessary for children. Beliefs are mainly based on a child's dental maturity, interest, capacity and age/size.

CONCLUSIONS

Most (87%) of the urban Mexican-American mothers in the study do not initiate oral hygiene practices in compliance with ADA recommendations. These findings have implications for educational messages.
