Interceptive orthodontics refers to all interventions and treatments that can be performed during the primary or mixed dentition with the aim of eliminating or minimizing dento-alveolar and skeletal disharmonies that can interfere with the normal growth and development of occlusion, function, aesthetics and the psychological wellbeing of children. The main purpose of interceptive orthodontics is to prepare an environment that will not interfere with the occlusal development in order to reduce the future need for prolonged complex mechanical orthodontic treatment. According to the American Association of Orthodontics the most suitable age for screening the paediatric population for interceptive intervention is 7 years of age. CPD/Clinical Relevance: To review the progress made in the field of interceptive orthodontics and discuss the current principles of early orthodontic intervention.

Introduction. This article’s purpose is to report a case where maxillary lateral incisors and mandibular central incisors are extracted and a canine substitution was performed as the best therapeutic option in order to obtain symmetry in a malocclusion with an upper lateral incisor with poor prognostic, solve moderate crowding, get enough space for the permanent dentition, and provide stability to the results. Case Report. An 11-year-old boy with straight profile with acute-to-normal nasolabial angle and protruded lips, mixed dentition, lower and upper severe crowding, and a bilateral molar angle Class I. The left maxillary lateral incisor failed endodontic treatment secondary to an intrusive traumatic lesion in the primary and permanent dentition. The treatment of choice was the extraction of both upper lateral incisors and both central lower incisors. The patient finished with molar and canine angle Class I and coincident midlines and was functionally stable; both lateral and protrusive jaw movements were effectively made by the first premolars and central incisors and canines without improper contacts of the rest of the teeth. Overbite of one-third and correct overjet were also achieved, and the esthetic outcome was satisfactory due to the composed material restorations of both the central and lateral incisors, as well as recontouring of the first maxillary premolars.

Bilateral mandibular tooth transposition is a relatively rare dental anomaly caused by distal migration of the mandibular lateral incisors and can be detected in the early mixed dentition by radiographic examination. Early diagnosis and interceptive intervention may reduce the risk of possible transposition between the mandibular canine and lateral incisor. This report illustrates the orthodontic management of bilateral mandibular canine-lateral incisor transposition. Correct positioning of the affected teeth was achieved on the left side while teeth on the right side were aligned in their transposed position. It demonstrates the outcome of good alignment of the teeth in the dental arch.

INTRODUCTION: Interceptive treatment of Class II, Division 1 malocclusion is a challenge orthodontists commonly face due to the different growth patterns they come across and the different treatment strategies they have available.OBJECTIVE: To report five cases of interceptive orthodontics performed with the aid of Klammt's elastic open activator (KEOA) to treat Class II, Division 1 malocclusion.METHODS: Treatment comprehends one or two phases; and the use of functional orthopedic appliances, whenever properly recommended, is able to minimize dentoskeletal discrepancies with consequent improvement in facial esthetics during the first stage of mixed dentition. The triad of diagnosis, correct appliance manufacture and patient's compliance is imperative to allow KEOA to contribute to Class II malocclusion treatment.RESULTS: Cases reported herein showed significant improvement in skeletal, dental and profile aspects, as evinced by cephalometric analysis and clinical photographs taken before, during and after interceptive orthodontics.

OBJECTIVE: To determine the prevalence of mesiodens in deciduous and mixed dentitions and its association with other dental anomalies. MATERIAL AND METHODS: Panoramic radiographs of 1,995 orthodontic patients were analyzed retrospectively, obtaining a final sample of 30 patients with mesiodens. The following aspects were analyzed: gender ; number of mesiodens; proportion between erupted and non-erupted mesiodens; initial position of the supernumerary tooth; related complications; treatment plan accomplished; and associated dental anomalies. The frequency of dental anomalies in the sample was compared to reference values for the general population using the chi-square test (c²), with a significance level set at 5%. RESULTS: The prevalence of mesiodens was 1.5% more common among males (1.5:1). Most of the mesiodens were non-erupted (75%) and in a vertical position, facing the oral cavity. Extraction of the mesiodens was the most common treatment. The main complications associated with mesiodens were: delayed eruption of permanent incisors (34.28%) and midline diastema (28.57%). From all the dental anomalies analyzed, only the prevalence of maxillary lateral incisor agenesis was higher in comparison to the general population. CONCLUSION: There was a low prevalence of mesiodens (1.5%) in deciduous and mixed dentition and the condition was not associated with other dental anomalies, except for the maxillary lateral incisor agenesis.

Objective: Assess whether the permanent maxillary canine (MC) has a natural tendency to erupt mesially in children with maxillary lateral incisors agenesis (MLIA), compared to children without agenesis. Study design: This retrospective, observational, cross-sectional study consisted of children between 5 and 12 years old divided into three groups: the first group with unilateral MLIA, in which an intraindividual analysis was performed, the second group presented bilateral MLIA, and the third group with patients without agenesis. These last two groups were matched for comparison interindividual, being pared by sex and maturation of the MC. Results: The canine position in the horizontal sector showed a clear mesial positioning of the MC on the agenesis side in individuals with unilateral MLIA (group 1) when compared with the counter lateral side; and in individuals with bilateral MLIA (Group 2) compared with control Individuals without agenesis (group 3). Even with the maintenance of this deciduous tooth in the dental arch, the MC keeps its tendency to mesial eruption. Conclusion: There is a greater tendency for mesial angulation of the maxillary canine in patients with MLIA, regardless of the presence or absence of deciduous lateral incisor.

Orthodontic treatment is thoroughly planned considering the patient’s facial and dental characteristics, the main complaint, treatment time and the orthodontist’s experience. Transposition is a form of ectopia, in which two adjacent teeth exchange positions in the dental arch. Transposition can be partial or complete. This article reports the treatment of a female patient with two kinds of tooth transposition managed in the mixed and permanent dentitions. A girl, aged eight years and three months, came to routine paediatric consultation with an ectopic permanent mandibular left lateral incisor in the mixed dentition. Radiographic analysis indicated partial transposition of the permanent mandibular left lateral incisor and canine (Md.L2.C), and development of a complete tooth transposition between the permanent maxillary right first pre-molar and canine (Mx.C.P1). The patient was treated in two phases. The first, in the mixed dentition, and the second, in the permanent dentition with a three-year follow-up between them. These challenging treatment approaches are described in detail, including the mechanics used. The key points of this treatment were early diagnosis of the ectopic mandibular lateral incisor, use of light forces and interphase patient follow-up. These determined the best time to start the second treatment phase, enabling achievement of aesthetic and functional outcomes, and the results remained stable one year after the end of orthodontic treatment.

Ugly duckling stage is a self-correcting anomaly seen during the mixed dentition period. It is characterised by the spacing between the upper incisors and proclination of teeth. It is seen that during this stage, parents take their child to the dentist to correct the malaligned teeth due to unawareness. The aim of this study is to assess the prevalence of pediatric dental patients reporting for tooth alignment during the ugly duckling stage. This retrospective cross-sectional study included patients who reported to saveetha dental college during June 2019- March 2020. Case records of about 10,000 patients were reviewed and 3363 patients were recruited under 8 to 13 years of age. Statistical analysis was done using SPSS software version 20.0. About 50.8% of patients who belonged to the age of 10 years reported for tooth alignment during an ugly duckling stage. Results were statistically significant for the association between age and chief complaint of anterior tooth alignment (p<0.05). Thus, the role of the dentists lies in making the parents aware that the ugly duckling stage is a self-correcting phenomenon and no orthodontic correction is required during this stage.

Tongue Thrust

<b><i>Introduction:</i></b> Tongue thrust is a frequent clinical condition characterized by abnormal patterns of movements and altered tongue posture on the mouth floor. It might contribute to determining alterations in the maxillofacial morphology and in the development of malocclusion. Several therapeutic options are available for treatment. In particular, the orofacial myofunctional therapy (OMT) is frequently adopted even if only few studies have analyzed its efficacy using validated instruments and no information is available regarding the effect of dentition on the results obtained with OMT. <b><i>Objective:</i></b> To evaluate the effect of OMT through a validated instrument and explore the role of dentition on its efficacy. <b><i>Methods:</i></b> A total of 22 consecutive patients with tongue thrust were enrolled. According to the presence of mixed or complete dentition, the cohort of patients was divided into 2 groups. Each patient underwent OMT according to the Garliner method (10 weekly sessions of 45 min each in hospital and daily exercises at home). The efficacy of OMT was evaluated using the Orofacial Myofunctional Evaluation with Scores (OMES), a validated protocol developed for the assessment of orofacial myofunctional disorders, and the Iowa Oral Performance Instrument (IOPI) to measure the peak isometric pressure exerted by the anterior and posterior part of the tongue. Both OMES and IOPI were administered before and at the end of the treatment. <b><i>Results:</i></b> A significant improvement in the OMES scores was demonstrated after OMT. No significant differences between the patients with intermediate and mixed dentition obtained in both the pre- and post-treatment conditions were demonstrated in the OMES scores. Similarly, a significant increase in the peak isometric tongue pressure in both the anterior and posterior parts of the tongue was demonstrated after OMT in the groups. No differences between the two groups in both the pre- and post-treatment conditions were demonstrated in the IOPI scores. <b><i>Conclusions:</i></b> OMT improves orofacial motricity and tongue strength in patients with tongue thrust regardless of the type of dentition.

A talon cusp is a dental anomaly commonly occurring in the permanent dentition compared to the primary dentition. It commonly affects the maxillary anterior teeth. In primary dentition, the most commonly affected tooth is the maxillary central incisors. This is a rare case report of a 5-year-old male patient with a talon cusp affecting the mandibular primary lateral incisor. Recognition and treatment of this anomaly at early stages is important to avoid complications.
