Eruption of first permanent molar among a group of Iraqi children in relation to nutritional status

Background/Aim: The timing of a tooth's eruption can be affected by a variety of factors. The nutritional status has an impact on the development of a child's body. The purpose of the study was to analyse the number of children aged 6 to 9 in an Iraqi Arab population who had erupted permanent first molars and to examine how nutritional status affected the timing and level of emergence. Methods: A total of 330 boys and girls, in first grade elementary school, made up the sample. First molars that had erupted were noted, along with the level of the eruption. Each child's nutritional status was evaluated by recording their height and weight and body mass index (BMI) value was compared to the 2007 WHO reference. Results: Girls had higher number of erupted molars than boys did and a correlation between the number of erupted teeth and nutritional condition existed, with a higher mean number of erupted molars in obese children. Conclusion: BMI had an impact on the timing of the eruption of permanent first molars, a result that was primarily observed in females.

Prevalence and Severity of Ectopic Eruption of First Permanent Molars in Pediatric Patients in Makkah, Saudi Arabia.

Background Early detection and management of ectopic eruption (EE) of first permanent molars (FPMs) are crucial to avoid complicated treatments later. Aim This study aimed to assess the prevalence and severity of EE of FPMs among children in Makkah, Saudi Arabia. Methods This retrospective study was based on a radiographic evaluation of 1,008 dental panoramic radiographs performed for children attending the Dental Educational Hospital at Umm Al-Qura University and the Security Forces Hospital in Makkah. Patients' age, sex, tooth location, and severity of EE were assessed. The study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guideline for cross-sectional studies. Results Of the 1,008 reviewed cases, 18 (1.79%) were diagnosed with EE of FPMs. Among the 11 male patients, 81.82% showed severe EE, while 57.14% exhibited moderately severe EE among the seven female patients. The prevalences of EE in the maxilla and mandible were 1.59% and 0.20%, respectively. In contrast, the occurrence of EE of FPMs was similar between the right and left sides. Conclusion In this study, the prevalence of EE of FPMs among children in Makkah was 1.79%. The frequency and severity were both greater in male patients compared to female patients. While significantly more EE of FPMs was observed in the maxilla than in the mandible, there was no significant difference between the right and left sides.

Influence of parental dental health knowledge and practices on their child’s oral health

Introduction: Parents’ oral health knowledge and attitude have a direct influence on oral health care options for their children. Aim: To evaluate attitude and knowledge level of parents toward their children’s dental health practice. Materials and methods: A questionnaire survey was conducted amongst randomly selected parents having children between the ages of 2 and 12 years from Benghazi, Libya. A questionnaire was distributed and completed by the parents to assess parent’s knowledge and awareness about the primary teeth. The data was statistical analyzed and comparison of the answers from the collected information was made. Results: One hundred and seventeen of parents completed the survey. Around 54.7% of participants were mothers and 35.9% were fathers, 9.4% were guardians, and their age was between 20 and 49 years. Although more than half of parents (59%) showed knowledge and attitude, the frequency of tooth brushing was low, only less than half of their children (40%) brushed teeth twice or more per day. Even though most of the parents had medium knowledge towards the primary teeth, dental visit was low, majority (69%) reported visiting the dentist only when child experienced of pain or toothache. And only third of parents had little knowledge about the time of eruption of first permanent molar. The majority (83.8%) would prefer to have their children’s carious teeth filled. Conclusion: Generally parent’s dental health awareness and knowledge were adequate but their attitude and practice were inadequate. Educating the parents and an increase in knowledge about caring of primary teeth and their significance effect on permanent teeth will encourage parents to provide better oral health to their children.

Ectopic Eruption of First Permanent Molars in Children from North-Western Romania.

Ectopic eruption of first permanent molars can lead to complications if left untreated. The aim of this study was to determine the prevalence of the ectopic eruption of first permanent molars in a sample of children from North-Western Romania, and to identify the characteristic of this anomaly in the studied population. We included patients aged between 5 and 9 years, and patients who needed a radiological examination for the diagnosis and treatment of dental or dento-maxillary diseases. The following exclusion criteria were applied: unclear or poor-quality radiographs; radiographs that belonged to patients who benefited from an orthodontic treatment before the panoramic radiograph was taken; patients who were undergoing orthodontic treatment when the radiograph was taken; and patients with local or general diseases that could influence dento-facial growth and development. Three degrees of severity were selected (moderate, severe, and very severe). The sample consisted of 438 patients, and 61 patients were diagnosed with ectopic eruption of first permanent molars (13.92%). Out of the 1752 analyzed molars, 103 were affected (5.87%). Patients with a moderate degree of ectopy were more frequently boys (56%, n = 14), while patients with a severe degree of ectopy were more frequently girls (52.8%, n = 19). Patients with a moderate degree of ectopy had significantly more frequently a unilateral position (57.1%, n = 16), while patients with a very severe degree of ectopy had significantly more frequently a bilateral position (36.4%, n = 12). The ectopic eruption was diagnosed at the level of the upper-right first permanent molar in a percentage of 18.4% (n = 19), at the level of the upper-left first permanent molar in a percentage of 17.5% (n = 18), at the level of the lower-right first permanent molar in a percentage of 32% (n = 33), and at the level of the lower-left first permanent molar in a percentage of 32% (n = 33). Although not very frequent, the ectopic eruption of first permanent molars is an important anomaly that should be early diagnosed, monitored and treated.

<strong>Correlation between stunting children aged 6-7 years in term of nutritional status and the eruption of permanent first molar</strong>

ABSTRACTIntroduction: Stunting is one of the nutritional problems that occur in Indonesia. Stunting is a condition where height is not following age. Physical growth is often used as an indicator to measure nutritional status. Permanent first molars are the first to erupt and normally erupt at 6-7 years old. Nutrition plays an important role in the growth and development of children. Since nutrition is one of the factors that influence tooth eruption, this study aimed to analyse the correlation between stunting children aged 6-7 years in terms of nutritional status and the eruption of the permanent first molar. Methods: This research used observational analytic correlation with a cross-sectional approach. Sampling was done using the cluster random sampling method to select elementary schools and total sampling to select children. The research was conducted at three elementary schools in the Jatinangor region. The number of samples was 200 children. The samples were measured for height and examination of the eruption status of permanent first molars. Result: It was found that 42 children were stunted. 12 children had not erupted their permanent first molars at all. There were 36% stunted children aged 6 years and 64% children aged 7 years. The results of the analysis using the Spearman rank correlation test obtained a correlation coefficient with r=0.185 and p-value=0.242 which showed the very weak strength and positive direction of the correlation. Conclusion: There is no correlation between nutritional status and eruption of permanent first molars in stunting children aged 6-7 years in the Jatinangor region.Keywords: nutritional status; stunting; tooth eruption; permanent first molar

Treatment of ectopic eruption of the maxillary first permanent molar in children and adolescents: A scoping review.

Ectopic eruption of the first permanent molar (EFUPM) is defined as its local disturbed eruptive behaviour, positioning too mesially against the distal aspect of the second upper primary molar during the developing mixed dentition. The EFUPM prevalence is up to 6% and affects both genders equally. The present study aimed to perform a scoping review to collect the most relevant studies published in the last 30 years and focused on the different strategies, traditional and novel, for treating irreversible uni- or bilateral EFUPM in children. This review also aimed to make recommendations and map the gaps in this clinical topic. An electronic and manual search was conducted in five databases according to previously established eligibility criteria, using different combinations of keywords, MeSH terms, and Boolean operators. Titles, abstracts, and full-text articles were screened and selected by pre-calibrated reviewers. A data charting was also accomplished for summarising the overview of the evidence. Paediatric dentists must learn to diagnose and treat this condition early in order to allow the prevention of future malocclusions and other clinical sequelae. Practitioners have at their disposal a variety of corrective options available for the successful resolution of EFUPM.

Automatic segmentation and detection of ectopic eruption of first permanent molars on panoramic radiographs based on nnU-Net.

The purpose of this research was to present an artificial intelligence (AI) model, which can automatically segment and detect ectopic eruption of first permanent molars (EMMs) in early mixed dentition on panoramic radiographs using the no-new-Net (nnU-Net) model. A total of 438 EMMs obtained from 285 panoramic radiographs were included in this study. An AI model based on nnU-Net was trained to segment and detect EMMs. The performance of the model was evaluated by the intersection over union (IoU), precision, F1-score, accuracy and FROC. Furthermore, the detecting performance of nnU-Net was compared with that of three dentists with different years of experience using the McNemar chi-squared test. The reliability of different dentists was evaluated by intraclass correlation coefficients (ICCs). The nnU-Net yielded an IoU of 0.834, a precision of 0.845, an F1-score of 0.902 and an accuracy of 0.990, whereas the dentists yielded a mean IoU of 0.530, a mean precision of 0.539, a mean F1-score of 0.699 and a mean accuracy of 0.811. The ICC of different dentists was 0.776. The statistical analysis of the McNemar chi-squared test showed that the nnU-Net results were statistically significant and superior to those of dentists (p<.05). This study validated an AI model based on nnU-Net for automatically segmenting and detecting EMMs more consistently and accurately on panoramic radiography.

Molar Incisor Hypomineralization-Influence on Dental Caries Experience Indexes: A Cross-sectional Study.

Aim and and objectiveTo evaluate the influence of the clinical characteristics inherent to Molar Incisor Hypomineralization on the values ​​and scores of the DMF-T and ICDAS indexes.Materials and methodsEight hundred and eight seven teeth were examined, from 39 individuals aged 3-14 years (8.95 ± 3.26), who had at least one first permanent molar (FPM) or second primary molar with signs of hypomineralization, according to the criteria of the European Academy of Paediatric Dentistry. Hypomineralized teeth were evaluated for the presence of restorations, post-eruptive breakdowns (PEB), and dental caries, being considered sound for the DMF-T when there was the presence of PEB without caries lesion. Chi-square and Kruskal Wallis tests (p ≤ 0.05) were used to detect differences.ResultsTwo hundred and five teeth showed signs of hypomineralization. The average number of opacities was influenced by the period of dentition, with more opacities when the primary dentition and the eruption of FPM and permanent incisors were complete (p ≥ 0.05). Hypomineralized teeth showed a higher DMF-T value, mainly of the decayed component (12%), in contrast to 2.5% of nonhypomineralized teeth. It was not possible to associate ICDAS scores 1 and 2 to hypomineralized surfaces, due to the overlap with the diagnosis of early enamel caries. The values ​​of this index changed in the presence of cavitation by caries (scores 3,4,5,6), but not in the presence of PEB.ConclusionDue to the impossibility of differential diagnosis with caries lesion, PEB, and opacities present in hypomineralized teeth tend to overestimate the values ​​and scores of the DMF-T and ICDAS, respectively.Clinical significanceMake future suggestions for epidemiological studies in the area.How to cite this articleVieira FG, Pintor AV, Silva FD, et al.

Standards for permanent tooth emergence in Sri Lankan children.

Determination of population specific standards on the timing and sequence of emergence of the permanent teeth is an essential requirement in pediatric dentistry. To establish the pattern and emergence time of permanent teeth in children in Sri Lanka. The cross sectional study was conducted with 3321 school children in the country. Children were randomly selected from each school from age 5- 20 years including both genders. Oral cavity was examined using a mouth mirror and probe with natural illumination and erupting stage of each permanent tooth were recorded. All permanent teeth except the third molars were included in the assessment. Females showed earlier eruption of teeth except for central incisors with statistical significance. All the mandibular teeth erupt earlier than their maxillary counterparts except for the premolars. Males showed early emergence of central incisors in left side of the mandible before eruption of first permanent molar. Males showed early eruption of 1st premolar before the eruption of canine in the mandible. The current study identified slightly late eruption of all the permanent teeth than in reported previous study in Sri Lanka. The results of the present study provide reliable references for the emergence of permanent teeth of children in Sri Lanka. Generally median emergence times were delayed compared with the previous study conducted in Sri Lanka.

Ectopic Eruption of First Permanent Molars for Pediatric Patients Attended King Saud University, Riyadh, Saudi Arabia: A Radiographic Study.

BackgroundEarly diagnosis and intervention of ectopically erupting first permanent molars (FPMs) are vital to avoiding later complex surgical or/and orthodontic treatment. Selection of proper type of intervention and simple treatment is considered as more convenient to use with children.PurposeThe aim of this retrospective radiographic cross-sectional study was to assess the prevalence and severity of ectopically erupting FPMs in children attending the Dental University Teaching Hospital (DUTH) at King Saud University, Riyadh, Saudi Arabia.MethodsThis retrospective study was conducted using panoramic radiographs (OPGs) of 2014 patients (973 females and 1041 males) aged from 5 to 8 years old who attended DUTH at King Saud University, Riyadh, Saudi Arabia. We assessed and recorded the age and gender of the subjects, the tooth number, arch, and location of the ectopic erupted FPMs, and the severity of resorption of the roots of the primary molars.ResultsOf 2014 reviewed OPGs, 45 (2.2%) cases were diagnosed with an ectopic eruption of the permanent first molar. The distribution of ectopic eruption based on gender showed that there was a higher prevalence in males 28 (2.9%) than in females 17 (1.6%). Of the 45 ectopic FPMs cases, 47 (78.33%) were detected in the maxilla, while 13 (21.66%) were seen in the mandible. Severe and moderate degrees of the ectopic eruption were found to be more common in the maxilla than in the mandible (p < 0.001).ConclusionClinicians should be aware of such conditions, as early diagnosis is essential for providing optimum dental care. To our knowledge, this study is the first to assess the prevalence of ectopically erupting FPMs in a Saudi population.

Evaluation of the mesio-distal positioning of the maxillary first permanent molar in individuals with ectopic eruption

Objective: To evaluate the mesial-distal positioning of the maxillary first permanent molar in children who present with ectopic eruption of the maxillary first permanent molar (PFMEE). Methods: panoramic radiographs and lateral cephalometric radiographs 12 children of both genders were evaluated. The study group was composed of 12 children with PFMEE and the control group was composed of 12 children with normal occlusion with the first upper permanent molar in occlusion. After selecting the exams from both groups and performing the anatomical tracings, linear and angular measurements were performed. In the lateral cephalometric radiographs the following angles were evaluated: SNGo.GN, SN.GN, SNA, SNB, ANB, 6mx.Palatal Plane and the 6mx.PTV distance. In the panoramic radiograph the angles 6mx.Infraorbital Plane and 6mx.Occlusal Plane were evaluated. Results: PFMEE can occur in individuals regardless of their skeletal pattern. The control group showed much greater angular measurements 6mx.Palatal Plane and 6mx.Infraorbital Plane. Conclusion: There is no relationship between PFMEE and craniofacial growth pattern, there is no direct relationship with the anteroposterior relationship of the apical bases and in cases of PFMEE the mesial angulation is reduced, representing lack of space for eruption of the first permanent molars.

Prevalence of Ectopic Eruption of First Permanent Molars in Panoramic Images of 5-8-Year-Old Children in Sari, Mazandaran Province, North of Iran in 2013-2020

Background Ectopic eruption is a tooth eruption disorder in which the tooth does not erupt in its proper eruption path. The most common type of ectopic eruption is the mesial eruption of the maxillary first permanent molar, which results in the loss of the second deciduous molars, resulting in a reduction in arch length and loss of space. Therefore, this study aimed to investigate the prevalence of ectopic growth of this tooth in children. Materials and Methods: This descriptive cross-sectional study was performed on panoramic radiographic images of children aged between 5-8 years. Census sampling method was used in this study. A general dentist under the supervision of an oral and maxillofacial radiologist assessed ectopic eruption according to a grading system described by Barberia et al., all radiographs. The data was analyzed using SPSS software version 16.0. Results: 772 panoramic radiographs were examined in this study, panoramic radiographs of 79 patients were considered to have ectopic eruption, which 61% of cases were in girls and 39% in boys. 25.6% of the patients had a mild, 60.3% had a moderate, and 14.1% had a severe ectopic eruption. All patients (except one) had a mesial ectopic eruption, 19% of the ectopic eruptions occurred in the maxilla, 59.4% in the mandible, and 59.5% in both jaws. Ectopic eruption in the mandible was more frequent in the mandible than in the maxilla and this finding was statistically significant (P <0.05). Conclusion The results of the present study showed that the frequency of ectopic eruption of the first permanent molars in Sari was 10.2%, which is higher than the values reported in studies in other regions of Iran.

Unlocking ectopically erupting permanent first molars using light wires

Background and OverviewEctopic eruption of permanent molars is one of the challenges that arise in the early mixed dentition period, particularly when the root of the primary second molar is resorbed due to mesial angulation of the impacted first molar. The authors introduce a simple and efficient method to unlock ectopically erupting first molars using a light wire. Case DescriptionThe authors describe the cases of 2 girls (8 and 7 years old) who sought treatment for locking of their maxillary and mandibular first molars, respectively. A 0.012-inch nickel titanium wire was compressed and bonded to the first molars and primary second molars to unlock the first molars. The primary second molars were splinted to the adjacent primary first molars and canines using bonded multistranded wires. As the compressed wires straightened over time, the locked first molars were tipped back without any substantial mesial movement of the primary teeth. After unlocking the molars, the nickel titanium wires were removed to allow spontaneous eruption of the first molars. Conclusions and Practical ImplicationsAlthough the primary molar roots were considerably resorbed, the ectopically erupting first molars were unlocked successfully without any substantial movement of the primary teeth. The clinical procedure was simple, and no laboratory procedures were needed. In addition, the anchorage burden was reduced with the use of light forces. The authors suggest that primary second molars with substantial root resorption due to ectopic eruption of permanent first molars can be saved simply and efficiently.

Distal Shoe Space Maintainer for the Premature Loss of Primary Second Molar in a 5-Year-Old Patient: A Case Report

Uneventful loss of deciduous second molar, afore the eruption of first permanent molar could lead tounadorned malocclusion due to undesired loss of space in the arch, tipping, crowding of the dental archand many other dental problems. So, to avoid further occlusal complications, it is desirable to place a spacemaintainer after successful extraction of the carious primary molar. This case report describes the removalof a primary mandibular second molar, followed by delivery of a distal shoe appliance before the eruptionof the first permanent molar.

Willet’s distal shoe appliance for early loss of second deciduous molar: A case report with 2 year follow up

Abstract&#x0D; The possibilities for space loss are even higher when second primary molars are lost early because they serve as a buttress for the eruption of first permanent molar. Distal shoe space maintainer is indicated in such type of cases. It is otherwise known as intra-alveolar appliance. In this article, we report the successful use of the distal shoe space maintainer in a 4yr old child.

Corrective Treatment of Ectopic Eruption of Permanent First Molars: Case Report

Ectopic eruption of a tooth is the process in which a tooth emerges in an abnormal position. The first permanent molar is the tooth that most frequently presents ectopic eruption, mostly because it is retained below the distal contour of the second temporary molar. The ectopic eruption may be reversible or irreversible, the latter of which requires corrective treatment to achieve correct eruption of the permanent molar in the arch. Treatments can be minimally invasive, such as the use of interproximal wedging, or more invasive orthodontic devices, such as brass wire, k-loops, Halterman devices, or wedging springs. The aim of this case report is to present two clinical cases where the ectopic eruption of permanent first molars is corrected using elastic separators. Conclusion:The elastic separators could be used successfully in cases of moderate or severe ectopic eruptions, not only in mild cases, as reported in most of the literature. The use of this technique does not require great cooperation from the patient, and it is low in cost.

ETIOPATHOGENESIS AND DIAGNOSTICS OF THE MANDIBULAR PERMANENT FIRST MOLARS RETENTION

The eruption of the first permanent molars is very important as it provides the harmony of the growth of the face and sufficient occlusion support. A delay in the eruption of this tooth can cause morphological, functional and aesthetic disturbances. These include reduced vertical size of the lower face, extruding the antagonist teeth, malloclusion formation, follicular cyst formation, pericoronal inflammation, and roots resorbtion of the adjacent teeth, as well as functional problems of dentoalveolar area, etc. In this regard, the issue of etiology, pathogenesis, early diagnostics and further treatment of lower first permanent molars retention is very relevant for modern orthodontics. In the literary review, morphological and radiological diagnostic criteria of eruption of first permanent lower molars have been presented. Materials and methods of the research. The article reviews and analyzes literature on the etiology, pathogenesis, early diagnostics of retention of the lower first permanent molars. Results The analysis of the literature pointed to a small number of studies regarding the disrupted eruption of first lower permanent molars. In most cases, they are presented as clinical cases. According to the world literature, the prevalence of delayed eruption of the first molar of the mandible was 0.01% to 0.04%. Data from the world literature indicate that the retention of the lower first molar is a polyfactoral disease. According to the etiological factors authors distinguish general and local. Local factors causing delay in teeth eruption include impaired pathway for teeth eruption, abnormality of the tooth form, hyperplasia, displacement of the rudiment because of the cyst and the tumour, loss of space for eruption, gingival fibrosis, idiopathic conditions. Systemic factors include endocrine disorders such as hypothyroidism, hyperthyroidism, hypoparathyroidism, rickets, craniofacial hypertrophy. In the literary review morphological and radiological diagnostic criteria of eruption disturbance of the first permanent lower molars are presented. Thus, the Korean scientists proposed to determine the depth of the retention, the angle of inclination and the space for their eruption on panoramic radiographs. The review presents the classification of retention types for the first permanent molars of the mandible.

Successful Treatment of Necrosed Primary Molars Using LSTR Technique by a New Combination of Antibiotics: A Case Series

Introduction: In this study we used combination of amoxicillin, metronidazole and clindamycin for treatment of 3 patients with infected primary molars until eruption of the first molars. Materials and Methods: A single session LSTR was done using combination of ciprofloxacin, metronidazole and andclindamycin at the ratio of 1:1:1. Conclusions: After 12- to 13-month follow-ups, the combination can greatly help save hopeless infected primary molars before eruption of permanent first molars due to effective space maintenance.

The orthodontic/paediatric interface part 1

Abstract: This series discusses the interface between orthodontics and other dental specialties. The first part of this four-part series will discuss the orthodontic/paediatric interface. It will discuss some common problems encountered in paediatric dentistry where orthodontic input is necessary including: enforced extraction of poor-quality teeth, unerupted maxillary incisors, crossbites, trauma, impacted canines, space maintainers and ectopic eruption of first permanent molars. The second part will discuss the orthodontic/restorative interface; the third will focus on the orthodontic/periodontal interface and the final article will discuss the orthodontic/endodontic interface. CPD/Clinical Relevance: Orthodontists and paediatric dentists work closely together to ensure that children have the appropriate treatment at the optimal time. General dental practitioners (GDPs) need to be able to identify and treat common problems and know when to refer to orthodontic or paediatric specialists.
