Abstract Background: Mixed dentition analysis is critical for early diagnosis of malocclusion because many malocclusions appear in this period. The aim of the present study is finding out specific prediction equation for estimation of mesio-distal width of maxillary unerupted canine at mixed dentition period depending on the width of upper and lowers central incisors. Materials and methods: Hundred orthodontic patients’ (50 males and 50 females) study casts visited a private clinic in Sulaimani City/Iraq were randomly selected and the largest mesio-distal dimensions of maxillary and mandibular central incisors and maxillary canines were measured by a digital calliper. The age range of patients was 14-24 years according to the inclusion criteria. Correlation and linear regression tests were applied on the collected data to find a prediction equation to estimate the mesio-distal width of maxillary permanent canine at early mixed dentition period relying on mesio-distal width of either mandibular or maxillary permanent central incisor. Results: Correlation coefficients of maxillary and mandibular central incisor were 0.664 and 0.639, respectively. It indicates a moderately strong correlation between the width of maxillary and mandibular central incisors and maxillary canine width. Establishment of valid practical prediction equations, one for maxillary central incisors (1.205+ 0.796 x Maxillary central incisor width) and the other for mandibular central incisors (1.205+ 1.205 x Mandibular central incisor width) with the former one being more reliable than the second one have a significant influence on construction of treatment plan at mixed dentition period. Conclusion: Moderately strong prediction equation is established to the mesio-distal width of maxillary permanent canine prior to their emergence in the oral cavity as an attempt to prevent their impaction or malposition.

Anterior crossbite refers to the abnormal vestibulolingual relationship in the sagittal dimension between one or more anterior superior and inferior anterior teeth. It can be classified as dental, functional or skeletal. Each has its own diagnostic criteria and specific treatment, and it is up to the dentist to know how to distinguish between these different natures of malocclusion. In this sense, the aim of this study is to show a case report about an ACM. Patient HCA, female, 7 years old, attending the Preventive Orthodontics Clinic of the Faculty of Dentistry of Araçatuba - UNESP, having as main complaint “untidy front tooth”. The patient has no history of systemic diseases or medication use. The patient was in the first transitional period of mixed dentition with her right maxillary central incisor in crossbite relationship with its antagonists mandibular central incisor. On both sides, the patient had the first permanent molars in Class I relationship, the deciduous second molars with mesial step and the deciduous canines in a Class I. Initially, an acrylic appliance with an expander was installed. Due to lack of cooperation, the treatment plan was changed and the patient received a fixed appliance with a 2x2 configuration, with brackets on maxillary central incisors and edgewise tubes on maxillary deciduous molars. In the lower arch, a bite lift was performed on the occlusal surface of mandibular deciduous molars to unblock the occlusion and facilitate the movement of right maxillary central incisor. The total treatment time was 60 days.

Abstract Aim The purpose of this case report is to describe the combined surgical and orthodontic treatment of two cases with an impacted maxillary central incisor and canine in the same quadrant and to discuss the causal relationship between them. Background The most common causes of canine impactions are usually the result of one or more factors such as a long path of eruption, tooth size-arch length discrepancies, abnormal position of the tooth bud, prolonged retention or early loss of the deciduous canine, trauma, the presence of an alveolar cleft, ankylosis, cystic or neoplastic formation, dilaceration of the root, supernumerary teeth, and odontomas. Although impaction of the maxillary central incisor is almost as prevalent as impacted canines its etiology is different. The principal factors involved in causing the anomaly are supernumerary teeth, odontomas, and trauma. Reports Case #1 A 10.5-year-old girl in the early mixed dentition stage presented with a chief complaint of the appearance of her anterior teeth. She had a Class I skeletal pattern and a history of trauma to the maxillary central incisors at age five with premature exfoliation. Radiographs revealed an impacted upper right central incisor in the region of the nasal floor, delayed eruption of the maxillary permanent central incisor, and the adjacent lateral incisor was inclined toward the edentulous space. Treatment was done in two stages consisting of surgical exposure and traction of the impacted central incisor and fixed orthodontic treatment. Case #2 An 11.5-year-old girl presented for orthodontic treatment with the chief complaint of an unerupted tooth and the appearance of her upper anterior teeth. She was in the late mixed dentition period with a Class III skeletal pattern along with an anterior cross-bite with some maxillary transverse deficiency. The maxillary right canine and central incisor were absent, but the maxillary right deciduous canine was still present. Treatment included arch expansion followed by surgical exposure and traction of the impacted teeth and fixed orthodontic treatment. Summary This case report provides some evidence of a significant environmental influence of an impacted maxillary central incisor on the path of eruption of the ipsilateral maxillary canine. When an impacted maxillary central incisor exists, the maxillary lateral incisor's root might be positioned distally into the path of eruption of the maxillary canine preventing its normal eruption. Ongoing assessment and early intervention might help to prevent such adverse situations from occurring. Citation Bayram M, Özer M, Sener I.

ABSTRACT Objectives: To describe qualitatively and quantitatively the directions and magnitudes of rotations of permanent maxillary central incisors and first molars in the mixed dentition in repaired complete unilateral cleft lip and palate (UCLP) and study their associations with absence of teeth in their vicinity. Materials and Methods: Dental casts and orthodontic records taken prior to orthodontic preparation for alveolar bone grafting of 74 children with repaired UCLP (53 male, 21 female; aged 8.9 ± 1.0 years) were studied. Directions and magnitudes of permanent maxillary central incisor and first molar rotations were recorded. Tooth absence was confirmed from longitudinal radiographic records. Incisor and molar rotations were analyzed in relation to the absence of teeth in their vicinity. Results: Distolabial rotation of the permanent maxillary central incisor was noted in 77.14% on the cleft side, while distopalatal rotation was noted in 82.19% on the noncleft side. Incisor rotation was greater when a permanent tooth was present distal to the cleft side central incisor, in the greater segment. The permanent maxillary first molar showed mesiopalatal rotation, which was greater on the cleft side and when there was absence of one or more teeth in the buccal segment. Conclusions: Presence and absence of teeth were associated with the severity of incisor and molar rotations in UCLP. Crowding of anterior teeth in the greater segment was associated with a greater magnitude of rotation of the cleft side permanent central incisor. Absence of one or more buccal segment teeth was associated with greater magnitude of rotation of the molar.

ABSTRACT Concurrent impaction and transposition of maxillary anterior teeth is uncommon and poses a challenge for dentists. Early diagnosis and management of eruption disturbances benefits esthetic and functional outcomes. This article describes the treatment of a teenager who had impactions of the left maxillary central incisor and canine as well as ipsilateral canine-lateral incisor transposition. Treatment alternatives and effective orthodontic techniques are delineated. To optimize the treatment results, the impacted maxillary canine was surgically exposed and orthodontically distalized with an innovative cantilever. Subsequently, the deeply impacted maxillary central incisor was uncovered and orthodontically mesialized into the arch. Finally, the displaced maxillary lateral incisor was brought into its normal position. The combined surgical-orthodontic approach resolved a difficult clinical issue and avoided additional restorations. An esthetic, functional outcome was achieved and satisfied the patient.

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.

This report describes the 10-year follow-up data of a patient who underwent fragment reattachment to the maxillary central incisor after coronal fracture with pulp exposure as well as the procedures followed for functional and esthetic adjustments. A 9-year-old female patient presented at the clinic of dentistry at the State University of Rio de Janeiro with a coronal fracture and pulp exposure of the right maxillary central incisor that had occurred immediately after an accident. The intact tooth fragment was recovered at the accident site and stored in milk. The treatment plan followed was to perform direct pulp capping and tooth fragment reattachment. When the patient was 14 years old, adhesion between fragment and remaining tooth was lost, and fragment reattachment was performed. Five years later, the same tooth presented clinical discoloration and absence of sensitivity during pulp vitality tests. Subsequently, a new treatment plan was formulated, which included endodontic treatment, followed by nonvital tooth bleaching and light-cured composite resin restoration. An esthetic and natural-looking restoration was achieved. Tooth fragment reattachment is not a temporary restorative technique and requires functional and esthetic adjustments over time to maintain the biomimetic characteristics of traumatized anterior teeth and predictable outcomes.
