Abstract Aim The aim of this study was to evaluate possible spontaneous space closure after extraction of first permanent molars in children and their eventual need for orthodontic treatment. Methods Twenty-seven children with at least one first permanent molar planned for extraction were enrolled in the study. The children were referred to the Department of Paediatric Dentistry, University of Oslo, between 2009 and 2017. All extracted teeth were severely affected by Molar Incisor Hypomineralisation and/or caries. The children and their parents had consented to extraction and follow-up. Data were analysed with SPSS 26. Results The age of the children was between 5.5 and 12.1 years (mean 8.7) at extraction. The mean follow-up time was 3.2 years (range 1.1–6.3). Sixteen children (59.3%) had all four molars extracted, five (18.5%) had three, five had two and one had one molar extracted. In the maxilla, the second permanent molar had erupted in the place of the first molar in all the children, and none of them needed orthodontic space closure. In the mandible, eight children (29.6%) needed orthodontic treatment to close the spaces after extraction. In three children, the second molar was not yet erupted and treatment need was not settled. Conclusion Extraction of severely affected first permanent molars before the eruption of the second molar is a treatment option causing little additional treatment in the majority of cases.

Extraction is very frequent indication in orthodontic planning, especially when there are crowding, biprotrusion, and aesthetically unpleasant profiles. Next to extraction comes space closure, which represents a challenge for orthodontists because of extended treatment time, discomfort created for the patient, tissue tolerance, and stability concerns. When it comes to what mechanics to choose for space closure, loops present two major advantages in relation to sliding mechanics: absence of abrasion and possibility to reach pure dental translation. A case is presented where an adult female patient with early loss of the first lower permanent molars, minor lower crowding, and tooth biprotrusion was treated with upper first bicuspids extraction along with upper and lower space closure done with T-loops to promote best space closure control in order to correct the malocclusion and enhance facial aesthetics.

The objective of this clinical case is to suggest a treatment approach for impaction of the maxillary first permanent molars. This approach allows access to the partially erupted tooth for orthodontic bonding and utilization of loops for distalization. An important detail is the non inclusion of the primary second molar in the orthodontic mechanics, in order to reduce the risk of early loss and preserve this tooth until exfoliation.

Introdution. Molar-incisor hypomineralisation is a disorder of dental enamel of a systemic origin. It may affect one or all four first permanent molars, and often involves permanent incisors. Aim. The aim of this study was to present views on aetiology, clinical picture and treatment of molar-incisor hypomineralisation. Material and methods. PubMed database was reviewed for years 2003-2017, the search criteria were: “molar incisor”, “hypomineralisation”, “permanent teeth”. Results. The aetiology of MIH is multifactorial and not fully explained. Authors agree that the general health during the first 3-4 years of life has a major impact on this disorder. The clinical picture includes demarcated white, yellow or brown tissue spots, and increased porosity of the enamel. Enamel damage and defects can also occur. Therapeutic management depends on the severity of the disease and includes intensive prevention, hard tissue reconstruction, and extractions. Conclusions. Due to the increasing prevalence of this disorder, special attention should be paid to children whose health status is or was bad in the first 3-4 years of life. They are at a higher risk for this condition.

Objectives: Demarcated opacities (DO) on teeth affected by Molar Incisor Hypomineralisation (MIH) were observed to investigate if parameters of DO existence and the number of teeth affected could be used to predict the progression of disease. Material and methods: In 2009, the MIH prevalence was 11.5% (n=51) among 446 subjects in Sarajevo, aged from 6 to 9 years. In subjects with MIH who gave consent for further participation (n=25), the teeth with DO were observed after a 12-month period. Results: our sample included 29 permanent incisors and 14 first permanent molars with DO. The number of teeth with light opacities was significantly higher than the number of teeth with dark opacities. Opacities were more numerous on surfaces which were not exposed to masticatory pressure. The size of tooth surface affected by DO occurrence ranged from 1.33% to 56.56%. The number of affected teeth ranged from two to six. A strong positive correlation between MIH progression and dark colored opacities located on the occlusal/incisal surface of teeth was noted. Larger part of tooth surface was affected by hypomineralisation in the case of dark-colored opacities. The DO presence on incisors was more likely to be located on vestibular surfaces and on the first permanent molars on their occlusal surfaces. Conclusions: The color of DO occurrence was the best predictor for MIH progression both independently and in combination with the number of affected teeth. Location of DO occurrence was a good independent predictor for MIH progression. It is important to collect information about color and location of DO presence.

Objectives: To obtain the views and opinions of specialist members of the British Orthodontic Society (BOS) and British Society of Paediatric Dentistry (BSPD) in relation to (1) the multidisciplinary management of patients affected by molar incisor hypomineralisation (MIH) and (2) the diagnosis and management of MIH-affected first permanent molars (FPMs) in four clinical scenarios, and compare the responses to those of an expert panel consensus. Design: A prospective cross-sectional study. Setting: Part 1: Eastman Dental Institute and part 2: online questionnaire. Methods: Four clinical scenarios showing patients with differing severities of MIH affected FPMs were considered by a panel of orthodontists and paediatric dentists to agree on the severity of MIH and management. A 21-item online questionnaire sent to both specialist groups, after pilot study. The questionnaire covered demographics, access to multidisciplinary clinics, clinicians’ opinions on various management aspects, and questions relating to the management of the same 4 clinical scenarios. Results: The overall response was 21.9% (20% of the orthodontists and 45% of the paediatric dentists). Approximately half of the respondents from both groups felt that these patients should be managed through a multidisciplinary treatment type clinic (49.0% of the orthodontists and 47.2% of the paediatric dentists). Only 40.3% of the orthodontists and 35.0% of the paediatric dentists agreed completely with the panel consensus on all management options. When assessing overall agreement on all four FPMs for all scenarios, agreement was predicted by severity of MIH (P<0.001) and complexity of malocclusion (P<0.001) where more complex malocclusions and more severe MIH resulted in poorer agreement, but specialty was not a significant predictor (P=0.21). Conclusion: The majority of the respondents from both groups, felt that managing patients with MIH affected FPMs is challenging. Approximately half of the orthodontists and the paediatric dentists, felt that MIH affected patients should be managed through a multidisciplinary type clinic. Managing more severe cases on multidisciplinary clinics is indicated, to incorporate specialist input into decision making.

Incisor Hypomineralisation

The management of compromised first permanent molars (FPMs) in children presents a clinical challenge to the dental team. Hypomineralised FPMs in molar incisor hypomineralisation (MIH) conditions could undergo post-eruptive breakdown, making them susceptible to caries, leading to their subsequent loss. The planned extraction of compromised FPMs is a valid alternative to complex restorative treatment. However, establishing the presence or absence of third permanent molars, amongst other considerations, is crucial to reaching a successful outcome. Clinicians should understand the importance of an orthodontic examination around the age of 8 years old with regard to establishing a differential therapeutic decision about the ideal timing of MIH-affected FPMs’ extraction in children. The aim of this article is to highlight that, with an interdisciplinary approach, a good outcome can be achieved following the extraction of poorly prognosed FPMs. The most cost-effective way of addressing MIH-affected FPMs is extraction, followed by orthodontic space closure when indicated. This obviates the need for the repeated restorative replacement and saves perfectly healthy premolars from being extracted for space creation in orthodontic treatment in several clinical scenarios.

RESUMEN. Antecedentes: La pérdida prematura de un molar primario conlleva a malposición de los dientes contiguos y del sucesor permanente. El efecto depende de las fuerzas que actúan sobre el diente, que están condicionadas a su vez por el estado de erupción del primer molar permanente. Propósito: Describir una opción de tratamiento para la pérdida prematura de segundos molares primarios hasta la erupción de los primeros molares permanentes. Descripción del caso: El caso clínico presentado involucra la rehabilitación oral de un niño de 5 años de edad que presentaba pérdida prematura de los segundos molares primarios. Se decidió colocar un mantenedor de espacio tipo zapato distal modificado. Se realizaron controles trimestrales y, cuando erupcionaron los primeros molares permanentes, aproximadamente a los nueve meses, se les utilizó como pilares para confeccionar el arco lingual. Conclusiones: El tratamiento propuesto mostró resultados satisfactorios en el mantenimiento del espacio hasta la erupción de los primeros molares permanentes.ABSTRACT. Background: The premature loss of a deciduous molar leads to malposition of adjacent teeth and the permanent successor. The effect depends on the forces acting on the tooth, which are conditioned at the same time by the grade of eruption of the first permanent molar. Purpose: To describe a treatment option for primary second molar premature loss until first permanent molars erupt. Case description: This clinical case involves the oral rehabilitation of a 5-year-old boy who lost prematurely his primary second molars. The decision was to place a modified distal shoe space maintainer. Controls were performed every three months and when the first permanent molars erupted, approximately nine months later they were used as pillars, to make the lingual arch. Conclusions: The treatment used showed satisfactory results in maintaining the space until permanent first molars erupted.

BackgroundMolar incisor hypomineralisation is defined as the hypomineralisation of systemic origin of one to four permanent first molars, and frequently associated with affected incisors. Till date, there is no data available on molar incisor hypomineralisation in any parts of Nepal.ObjectiveTo determine the prevalence and characteristics of Molar incisor hypomineralisation in 7 to 12 years old school children of Kavre.MethodA total of 749 school children of age 7 to 12 years from four different randomly selected schools with at least one of the first permanent molars fully or partially erupted were evaluated using European Academy of Paediatric Dentistry criteria for molar incisor hypomineralisation. The examinations were conducted at respective schools by a single calibrated examiner.ResultMolar incisor hypomineralisation was present in 13.7% of children. No gender differences were found.The mild type of defect (without structural loss of tooth) was the most prevalent type of molar incisor hypomineralisation with white/creamy demarcated opacities more frequent than yellow/brown demarcated opacities. Post eruptive breakdown was more in boys than in girls and this difference was statistically significant (p<0.05). Also, maxillary molars were affected more than mandibular molars and this difference was also statistically significant (p<0.05).ConclusionThe prevalence of molar incisor hypomineralisation in Kavre was 13.7%.Demarcated opacities were more prevalent than breakdown. The hypomineralised defect was more prevalent in maxillary teeth than in mandibular teeth. The severity of defect increased with age and there was no difference in prevalence between girls and boys.Kathmandu University Medical Journal Vol.12(1) 2014: 38-42
