Modificări gingivale în sarcină-manifestări clinice și recomandări practice

Fluctuations in female hormones have a complex infl uence on gum health. Pregnancy greatly infl uences the health of the whole body, including the gingival tissues, and correlates with a high degree of carious and gingival damage. Performing regular dental check-ups to keep plaque under control, along with maintaining personalized hygiene at home, can lessen the impact and risks of hormonal fl uctuations on the gums.

Preventive Dental Behaviors among U. S. College Students: Application of the Health Belief Model

Objectives: Evaluate college students' preventive dental behaviors based on the Health Belief Model (HBM), identify key constructs of HBM to promote preventive dental behaviors, and determine the impact of the COVID-19 pandemic on college students' preventive dental behaviors. Methods: The data for this cross- sectional study were collected from 550 college students (ages 18 to 25; 69.8% female) through an online survey. Participants were recruited through a random sampling process. Descriptive statistics were used in the analysis of quantitative data. A multivariate analysis of variance was applied to examine the relationship between HBM and preventive dental behaviors. In addition, chi-square was used to determine the prevalence of preventive dental behaviors associated with dental knowledge. Results: Perceived barriers and self- efficacy were significant predictors of preventive dental behaviors ( p < 0.001). Also, a significantly higher proportion of students with sufficient dental knowledge met the recommendations for tooth brushing and dental checkups compared to those with deficient or moderate dental knowledge ( p < 0.05). Although most of the participants reported no influence of COVID-19 on their preventive dental behaviors, a considerable number of the students still reported the influences of COVID-19 (tooth brushing: 20.9%; tooth flossing: 10.6%; dental checkups: 18.8%). Conclusions: The Health Belief Model could be an effective framework to promote preventive dental behaviors for college students, particularly, using perceived barriers and self-efficacy.

스케일링 교육경험 및 치과위생사의 태도가 치과공포에 미치는 영향

The incidence of chronic diseases such as oral diseases can be reduced through regular dental checkups and preventive procedures. However, some individuals are unable to visit dental clinics when necessary due to a fear of dentistry. A self-administered survey was conducted on 297 adults in their 20s to 60s living in Gangwon-do and Gyeonggi-do to measure dental fear, and the collected data were analyzed using SPSS 22. Dental fear increased with age however, it decreased with scaling education experience. In addition, the dental hygienist's friendliness and general explanation of scaling were important factors in lowering the subject's dental fear. Therefore, oral health education by dental hygienists is necessary to overcome the fear of dentistry, visit the dentist, participate in preventive treatment, and manage oral cavity and overall health.

Evaluación del estado de salud bucal, necesidades autopercibidas, necesidades insatisfechas y barreras para la utilización de servicios dentales entre la población de edad avanzada institucionalizada en Chennai, India: Un estudio transversal

Aim: The aim of the study was to assess the oral health status and identify oral health perceived and unmet needs, and barriers in utilization of dental services among institutionalized elderly population in Chennai. Materials and Methods: Across sectional study was conducted among institutionalized an elderly population aged 65-74 years. Oral health status was assessed using the WHO Oral Health Assessment Form (2013). Self-perceived oral health needs and barriers in the utilization of dental services were assessed using a pre-tested questionnaire. Descriptive statistics and Pearson Chi Square Test was done to analyse the data. Results: There was a high frequency of periodontitis among the study participants. The unmet oral health needs were high. The self-perceived oral health condition was good among the study participants. The major barrier for utilization of dental services was the lack of information on oral health. Conclusions: In India, which is a developing country, a low level of dental care results from low-level financing of the Indian health care system. This, however, does not mean that even in the current poor economic conditions, it is impossible to improve the dental awareness of the residents of care homes. The improvement is also possible through the inclusion of dental check-ups into the schedule of general dental examinations of the residents performed once in 6 months.

Variations in morphology of permanent maxillary lateral incisors and its impact on oral hygiene and diseases

The permanent maxillary lateral incisors are of great importance from an aesthetic standpoint, as any variation in their shape can lead to an unfavorable visual appearance. Furthermore, morphological variations such as peg-shaped, barrel-shaped, shovel-shaped, and canine-shaped teeth can impact oral hygiene and lead to additional health problems. The etiology of these variations is multifactorial, including genetic, epigenetic, and environmental factors. This paper aims to provide a comprehensive overview of the most common morphological variations of the permanent lateral incisors, including their causes, associated dilemmas, treatment modalities, and the various health and hygiene issues associated with these diverse physical characteristics. By highlighting the potential health and hygiene issues associated with these variations, this paper aims to increase awareness among dental professionals and the general public about the importance of regular dental care and check-ups to maintain oral health and aesthetics. A comprehensive understanding of the causes, dilemmas, and treatment modalities of these morphological variations can aid dental professionals in providing effective and personalized care to their patients. In conclusion, the morphology of the permanent maxillary lateral incisors plays a critical role in dental aesthetics, hygiene, and health.

Rationale of first dental visit among 12-15 year old children in a field practice area-a transverse survey

Many children were suffering with oral health problems such as dental caries, gingival infections & malocclusions. Early identification of these problems plays a decisive role in prevention of oral diseases. First dental visit within first year of life is an important milestone in child's life. Aim & Objectives - To assess first dental visit and reasons for seeking dental care at first visit at two different locations in a city from South India. Methods - A cross sectional questionnaire survey along with oral examination were carried out among school children (n=400). Descriptive statistics and independent t test were done. Results - Mean DMFT and OHI-S scores, 0.92 ± 1.194 and 0.89 ± 1.578, were higher among children having access to dental institution. Approximately 62.5% near institution and 66% away from institution reported that, their first direct contact with a dental professional was at school. General dental checkup was the dominant reason for first dental visit followed by dental caries and tooth pain. Conclusion - Significant differences were found among the groups in relation to first dental visit and its reasons. So it is necessary to work out recommendations towards preventive care rather than curative. Key Words - First dental visit, Reasons, School Children

Oral health-related quality of life and depressive symptoms in adults: longitudinal associations of the English Longitudinal Study of Ageing (ELSA)

BackgroundLittle is known about the relationship between oral health status and depressive symptoms in adults in England. The aim of this study was to examine the longitudinal association between oral health parameters and depressive symptoms in adults in England.MethodsData were obtained from the English Longitudinal Study of Aging (ELSA), which included information on self-rated oral health, oral impairment in daily life (Oral Impacts on Daily Performances, OIDP), and depressive symptoms (Center for Epidemiologic Studies Depression Scale, CES-D) in 6790 adults aged ≥ 50 years. Wave 3 data were used as baseline, while Waves 5 and 7 were used for follow-up assessments. Logistic regression was used to determine whether depressive symptoms at baseline anticipated self-rated oral health and OIDP and whether oral health status (at baseline) was associated with the development of depressive symptoms at follow-up assessment.ResultsParticipants with poor self-rated oral health were at higher risk of developing depressive symptoms, even after adjusting for behavioral, clinical, and sociodemographic characteristics (OR = 1.69, 95% CI 1.38–2.07). Similarly, having oral impacts on daily performances were associated with the development of depressive symptoms: The OR for developing depressive symptoms at Wave 5 or 7 was 2.19 (95% CI 1.62–2.96) after adjustment for all covariates. Participants with depressive symptoms at baseline were more likely to report poor self-rated oral health (OR = 1.93, 95% CI 1.52–2.44) or one or more oral impacts (OR = 1.86, 95% CI 1.45–2.40) at follow-up than those without depressive symptoms at baseline, even after adjusting for confounders.ConclusionsIn the present study, a bidirectional association was found between depressive symptoms and poor oral health in older adults. Maintaining good oral health in older adults may be a protective factor against depressive symptoms. Therefore, more attention should be paid to promoting oral health awareness in older adults, including encouraging regular dental checkups, proper toothbrushing and flossing techniques, and healthy lifestyles.

Factors influencing the likelihood of dental service checkup: results from a survey in Saudi Arabia.

The funding and delivery of healthcare including dental care in the Kingdom of Saudi Arabia (KSA, or Saudi Arabia) is undergoing a process of reform. To inform this process, it is important that policymakers are aware of the relationships between service use, specific types of use, and the factors that influence this. Currently, there is a paucity of research in this area in KSA that examines dental service use for checkups at a national level and none that examines differences in this use across regions or that examines explicitly the role of income. This study uses the most recent version of the Saudi Health Interview Survey (SHIS) to examine the relationships between the use of dental services for a checkup and socio-demographic characteristics of respondents. Particular focus is given to the differences between regions in service use and the role of socio-demographics within regions. Data were taken from SHIS 2013. Descriptive statistics (means and standard errors) were used to characterize the sample. Logistic regression analyses were used to examine the relationship between checkups in the past 12 months and a range of covariates including income and region. The analysis was repeated for sub-samples based on specific regions. No attempt was made to impute missing values. A sample of 7603 respondents provided complete data for analysis. Fifty-one per cent of the respondents were male, 29% were educated at least to degree level, 25% reported that they floss at least once per day, 69% reported that they brushed their teeth at least once per day, and 11% reported that they had visited the dentist for a checkup in the preceding 12 months. Logistic regression analyses revealed income, region, and oral hygiene habits to be among the significant determinants of the likelihood of dental checkup in the preceding 12 months. In logistic regression analyses at the regional level, different relationships were evident between checkups and socio-demographic characteristics across regions. Region and income are significant determinants of dental service use for checkups. Differences exist between regions in the relationship between socio-demographic characteristics and the likelihood of getting checkups. Policy changes should reflect the potential differences they might have across regions for which the role of socio-demographic characteristics varies.

ODONTOGENIC MAXILLOFACIAL CELLULITIS IN CHILDREN: EPIDEMIOLOGICAL ASPECTS AND PREDICTORS

Introduction: Odontogenic maxillofacial cellulitis is a serious acute infection of the cellulo-adipose tissues of the face and neck of dental origin that is life-threatening. The aim of this work is to determine the epidemiological aspects and predictive factors of odontogenic maxillofacial cellulitis. Materials and methods: This is a bi-centric, retrospective, cross-sectional, descriptive study, from March 2016 to July 2022, carried out in the stomatology and maxillofacial surgery department and the ENT department. All patients under 18 years of age hospitalised for management of odontogenic maxillofacial cellulitis were included. Patients over 18 years of age and those with non-odontogenic cellulitis were not included. The parameters studied were frequency, age, sex, place of residence, school attendance, tooth brushing, dental check-ups, consumption of cariogenic foods, use of NSAIDs and self-medication. Results: This study collected 72 files over a period of 6 years. The frequency was 5.05% compared to hospitalisations in general and 28.33% compared to hospitalisations for cellulitis only. There were 42 boys with a sex ratio of 1.4. The mean age was 9.03±5.71 years. 93% lived in urban areas. 84.7% had self-medicated for toothache. 52.8% had used non-steroidal anti-inflammatory drugs. Conclusion: Quite common condition in children. It is promoted by the consumption of cariogenic foods and self-medication with non-steroidal anti-inflammatory drugs.

Dental care of disabled people: Descriptive cross-sectional study of social and medico-social establishments

The first objective of this study, concerning the intervention of a dentist in social and medico-social establishments (SMSE), was to diagnose the oral care needs of disabled people (DP). The second objective was to raise awareness of a prevention and follow-up protocol among caregiving staff. We carried out this descriptive cross-sectional study from October 2016 to October 2018, in twenty SMSEs in Essonne. It involved a cohort of 663 volunteer DP, i.e., over 81 percent of the DP accommodated in these establishments. We analyzed DP’s oral hygiene and health indicators, as well as changes in professional practices following simulation workshops, using Pearson’s Chi-square test and Cramer’s test to assess the existence of relationships between variables and their intensity, respectively. Of the 96 percent of DP who accepted a full screening, three-quarters had dental plaque and two-thirds had gingival inflammation, these pathologies being more frequent in the over-20s (p< 0.001 | Cramer’s V=0.26). Only 14 percent had good oral health. Six months later, seventeen SMSEs had recorded dental check-ups in their medical records, and eight SMSEs had introduced brushing after dinner and breakfast, compared with ten and seven respectively before the intervention. This study confirmed the need for SMSEs to carry out dental screening. The involvement of establishments in monitoring the oral hygiene of DP must be strengthened.

Factors Affecting the Seeking of Orthodontic Treatment of Turkish Adults

Objective The aim of this study is to determine the factors that are effective in seeking orthodontic treatment of Turkish adult individuals and to evaluate the effects of demographic characteristics such as gender, age, marital status, and educational status of the participants on these factors comparatively. Methods A questionnaire-based study was applied to participants who want to receive orthodontic treatment. In the first part, the participants were asked about demographic information such as gender, age, marital status, occupation, and educational status. A total of 542 people (330 female and 212 male) were included in our study. The age of participants included in the study ranged between 18 and 45. Questions about oral hygiene, regular dental check-ups and the factors that affect in seeking orthodontic treatment were asked in the second part of the questionnaire. Results Young adults and females were found to have a higher rate of seeking orthodontic treatment. When the participants were asked what led them to orthodontic treatment, 72.1% of the participants stated that they thought it as a necessity such that they should receive orthodontic treatment. Material selection in orthodontic treatment shows statistical significance according to demographic characteristics ( p &lt; 0.05). While 48% of the participants in the 18ȓ24 age group preferred metal orthodontic brackets, 37.9% of the participants in the 25–45 age group preferred clear aligner. Moreover, 40.4% of the married participants preferred clear aligner, while 45.1% of the single participants preferred metal orthodontic brackets. Conclusion The factors in seeking orthodontic treatment of individuals vary according to demographic characteristics and social environment of individuals.

Workplace oral health promotion activities among community-aged care workers: A qualitative exploration.

The workplace is an ideal-and priority-setting for health promotion activities. Developing and implementing workplace health promotion interventions, including oral health promotion activities, can help create health-supporting workplace environments. To pilot workplace oral health promotion activities among staff working in the aged care sector, report their impact and explore participants' views on the factors that contribute to participation and effectiveness. This study comprised three phases: (i) the development and face validation of the resources, (ii) a 3-h educational session and (iii) five interview sessions with participants 4-6 weeks following the education session. The recorded interviews were transcribed verbatim and analysed thematically. Eleven community-aged care workforce were invited to five feedback sessions. Ten participants were female and ranged in age from 18 to 64. All participants gave favourable comments about the content and delivery of the training session and accompanying resources. The participants felt that the benefits of WOHP include improved staff knowledge, awareness and oral care routine, the ability to share (and put into practice) the gained knowledge and information with their dependants, a lower risk of having poor oral health that adversely affects their well-being and work tasks, and potentially beneficial impacts on the organization's staff roster. Their attendance in the WOHP was facilitated by being paid to attend and scheduling the sessions during work time. Future WOHP suggestions include the possibility of a one-stop dental check-up at the workplace or staff dental care discounts from local dental practitioners and combining oral health with other health promotion activities. Planning and implementing WOHP was deemed acceptable and feasible in this study context and successfully achieved short-term impacts among community-aged care workers. Appropriate times and locations, organizational arrangements and a variety of delivery options contributed to successful programme planning and implementation.

Types, accuracy, and efficacy of salivary biomarkers in periodontal diagnosis

Periodontal diseases primarily occur due, to infections and inflammation that affect the gums and bone structures supporting the teeth. In the stage, known as gingivitis the gums may become swollen turn red and bleed easily. These health issues not impact health but also have broader implications for overall well-being, including tooth loss, discomfort, bad breath and an increased vulnerability, to chronic illnesses. The main objective of this review is to examine aspects pertaining to diseases encompassing clinical indications, methods, for diagnosis, available treatment choices, and preventive strategies. This research meticulously examines the types of these diseases, their stages, and their causes. It also discusses the approaches and criteria used to diagnose these conditions. Additionally, the paper provides an evaluation of treatment alternatives and strategic frameworks, for managing pathologies. This includes both surgical approaches, well as supportive therapies. The paper emphasizes the importance of measures. Maintaining oral health through consistent dental hygiene practices, regular dental checkups, and necessary lifestyle adjustments. In conclusion, while periodontal diseases pose challenges in practice they can be controlled and prevented through collaboration, between dental practitioners, dental hygienists, and active patient participation.

A supernumerary tooth: A case report of a mesiodens

Introduction: Mesiodens is an erupted supernumerary tooth located between the maxillary central incisors. Case Report: This report presents a case of a fully erupted mesiodens in a 10-year-old girl causing incisor displacement. The patient presented for a dental checkup with dental caries and a mesiodens visible on clinical exam. Radiographs confirmed eruption of the mesiodens. Extraction was planned to prevent further crowding. Erupted mesiodens can still cause complications like malocclusion and cysts. Extraction is the treatment of choice. Conclusion: Early diagnosis allowed for removal before additional orthodontic problems. Monitoring and restorative care are needed after extraction. This highlights the importance of prompt mesiodens diagnosis and extraction even when fully erupted.

Oral manifestations found among illicit drugs users

Illicit drug use is an intricate challenge that currently affects an individual's health and overall well-being. This review study provides insight into the availability of information regarding the examination of the signs, treatment approaches, and broader consequences related to health problems among individuals who use drugs. The clinical indicators of drug consumption on oral health encompass issues such as dry mouth (xerostomia), gum problems, teeth grinding (bruxism), and dental cavities. These manifestations contribute to immediate discomfort and elevate the risk of long-term dental complications, underscoring the pressing need for intervention and care. Effective management strategies involve a comprehensive approach, incorporating preventive measures, timely treatment, and a compassionate understanding of the unique challenges faced by drug users. Preventive efforts, such as education and regular dental check-ups, serve as critical components in mitigating the clinical manifestations. Treatment strategies, including restorative procedures and periodontal therapy, play a pivotal role in addressing immediate oral health concerns. However, the management of oral health issues extends beyond the dental chair. Acknowledging the hurdles faced by individuals who use drugs, including economic factors and social prejudice, underscores the significance of adopting a comprehensive approach to providing support and assistance. Integrating oral health services with substance abuse treatment presents a promising avenue for comprehensive healthcare. This collaborative approach addresses oral health issues and acknowledges the bidirectional relationship between substance abuse and oral health. In summary, it is essential to comprehend the relationship between illicit drug use and oral health. By implementing management strategies, we can potentially reduce suffering, improve quality of life, and enhance health for individuals affected by substance abuse. This holistic approach emphasizes the significance of acknowledging and addressing these population’s health requirements within a broader healthcare framework.

Proteomic analysis of salivary inflammatory biomarkers of developmental gingival enlargements in patients with West and Noonan syndromes: a preliminary pilot single-center retrospective study.

The aim of the preliminary pilot single-center retrospective cross-sectional study was to analyze and compare the presence of non-secretory salivary inflammatory biomarkers in pediatric patients with West syndrome, Noonan syndrome, and a healthy control group. A total of 60 saliva samples were collected during dental check-ups. The saliva samples collected were analyzed by liquid chromatography. The results were analyzed with a t-test, and the statistical significance was given by a p-value lower than 0.05. We found statistical significance for defensin α1 (p=0.006) and thymosin β4 (p=0.025) in the Noonan syndrome. In the West syndrome, only the defensin α1 had a statistically significant difference with the other groups (p=0.022). Proteomic analysis revealed an overexpression of peptides related to the innate (thymosin β4) and acquired (defensin α1, α3) immunity. West and Noonan's syndromes showed the overexpression of molecular biomarkers involved in the pathogenesis of chronic periodontitis. The inflammatory status is triggered and amplified by the abnormal overgrowth of gingival tissues, the amplified release of proinflammatory cytokines from the immune cells, and the poor cooperation in maintaining adequate oral hygiene.

Correlates of childhood caries: A study in Qatar.

The prevalance of dental caries in children in Qatar is high, which necessitates preventive efforts. To identify the sociodemographic and behavioural correlates of dental caries in the primary dentition of children 4- to 8-year-olds in Qatar. Weighted data from the Qatar Child Oral Health Survey 2017 were analysed for caries prevalence (dmft>0) and experience (dmft). Sociodemographic and behavioural variables were also drawn from the survey. Among the 1154 children, caries prevalence was 69.3% (95%CI [63.4, 74.5]) and experience at 3.8 dmft (95%CI [3.3, 4.2]). The prevalence ratio (PR) 0.82 (0.72, 0.94) was lower among younger than in older children; those for non-Qatari nationality Arabic PR 0.91 (0.82, 1.00) and Other PR 0.75 (0.57, 0.99) than for Qatari nationality; those attending international kindergartens/schools PR 0.89 (0.80, 0.99) than independent schools; and whose parents had university-level education PR 0.85 (0.75,0.95) than did not. Caries prevalence was lower among those toothbrushing by age 3 years PR 0.88 (0.80,0.99) than later; children with low/intermediate sugar exposures PR 0.85 (0.74,0.97) and 0.89 (0.79,1.00) than those with high exposures; children with a dental check-up PR 0.68 (0.53,0.87) than those without; and children who drank bottled water with some fluoride PR 0.89 (0.80,0.99) than those who did not. Findings were similar for dmft. In conclusion caries prevalence varied but was high across sociodemographic correlates indicating vulnerablity. Interventions focusing on behaviours - such as toothbrushing, reducing sugar intake, check-up and encouraging intake of water with fluoride - are needed.

Prevalence of dental caries and oral hygiene practices among elderly people: a descriptive cross-sectional study from Nepal

Background: Dental caries is one of the most prevalent oral diseases of public health concern affecting elder people. The main reasons for caries arise in elderly people are increase in sugar consumption, poor oral hygiene, microbial plaque, periodontal disease, dietary habits, low socioeconomic status and infrequent dental visits. The oral hygiene is essential to general health and quality of life. Methods: A descriptive cross-sectional study was conducted among 246 elder people. Systematic random sampling was used for data collection. The data collection was done between 15 April to 07 May 2017. Results: The overall prevalence of dental caries in study population was 88.57%. The mean DMFT of all study participants was 17.13 (SD=10.48; participants were allocated a DMFT of 32). Majority of elder people (56.33%) had experience of pain and discomfort in their teeth within 12 months. The gender, marital status, diet, socio-economic status, medication, method of cleaning, frequency of cleaning, dental visit and tobacco chewing were factors that determines dental caries. Regular dental checkup (11%) was very poor. Majority of respondents preferred tea with sugar, biscuits/cake, chocolate and soft drinks (64%). Conclusions: The study showed that the prevalence of dental caries among elderly people in Rajdevi Rural Municipality, Rautahat District, Nepal was high. The awareness should be provided to local residents regarding the importance of good brushing habits and regular dental visits. Oral health policies are needed revised and implemented focusing on the special needs of this population to improve their quality of life.

Early diagnosis of aortic calcification through dental X-ray examination for dental pulp stones

Vascular calcification, an ectopic calcification exacerbated by aging and renal dysfunction, is closely associated with cardiovascular disease. However, early detection indicators are limited. This study focused on dental pulp stones, ectopic calcifications found in oral tissues that are easily identifiable on dental radiographs. Our investigation explored the frequency and timing of these calcifications in different locations and their relationship to aortic calcification. In cadavers, we examined the association between the frequency of dental pulp stones and aortic calcification, revealing a significant association. Notably, dental pulp stones appeared prior to aortic calcification. Using a rat model of hyperphosphatemia, we confirmed that dental pulp stones formed earlier than calcification in the aortic arch. Interestingly, there were very few instances of aortic calcification without dental pulp stones. Additionally, we conducted cell culture experiments with vascular smooth muscle cells (SMCs) and dental pulp cells (DPCs) to explore the regulatory mechanism underlying high phosphate-mediated calcification. We found that DPCs produced calcification deposits more rapidly and exhibited a stronger augmentation of osteoblast differentiation markers compared with SMCs. In conclusion, the observation of dental pulp stones through X-ray examination during dental checkups could be a valuable method for early diagnosis of aortic calcification risk.

Timing of Primary Tooth Eruption in Infants Observed by Their Parents.

The timing of primary teeth eruption is a visible indicator of infant physical growth other than body weight or height. It also reflects neurological integrity and development as well as nutrition, socioeconomic state, or underlying diseases. Therefore, the timing of primary teeth eruption is one of the major concerns for parents in health checkups for infants and children. However, the detailed developmental timing of teeth eruption differs depending on the survey methodology, country, or generation. We hypothesized that the timing of primary teeth eruption differs between the medical checkup by dentists and the daily records by parents. We conducted a questionnaire survey on the date of eruption of primary teeth as an adjunct study among Miyagi Regional Center participants in the Japan Environment and Children's Study (JECS), a large-scale birth cohort study. A total of 1695 responses (3793 participants) were analyzed. The median ages of eruption were 7.1 months (male) and 7.6 months (female) for mandibular primary central incisors, 8.7 months (male) and 9.2 months (female) for maxillary primary central incisors, 10.0 months (male) and 10.3 months (female) for maxillary primary lateral incisors, and 10.4 months (male) and 10.8 months (female) for mandibular primary lateral incisors, which were earlier than the reported timings based on dental check-ups. Comparing the eruption time of preterm and term infants, the eruption time was earlier in preterm infants in the corrected ages. The eruption timing observed and described by the parents is earlier than that examined by dentists at regular check-ups. In addition to examining the primary teeth eruption of full-term birth children, we also examined that of preterm birth children because of the increasing number of premature births. To the best of our knowledge, this is the first report from a large cohort study to clarify the eruption time of primary teeth monitored by parents.
