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.

Aim and objective: The objective of this in-vivo study was to evaluate toothwise and archwise sulcus depth in human primary, mixed and permanent dentition of Indian population.Method: The study included 40 subjects (22 males and 18 females) of an age range 4-25 years. Subjects were divided into 3 groups – the primary dentition (4-6 years) mixed dentition (7-13 years) and adult dentition (16-25 years). All the parameters were measured in upper and lower anterior segments.Results: Gingival sulcus depth (GSD) was measured archwise and toothwise in different dentitions and overall dentition wise without differentiating archwise and toothwise. GSD was significantly higher in maxillary mixed dentition (1.75±0.75) followed by permanent and primary dentition. In all the dentition, maxillary central incisor showed significant GSD.Conclusion: The sulcus depth is maximum in mixed dentition followed by primary and permanent dentitions and significantly higher in maxillary central incisor.

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.

Patient Reported

Background Dilaceration, a developmental disturbance, is thought to be due to trauma leading to change in the position of the calcified portion of the tooth and the tooth is formed at an angle. Such an injury to a permanent tooth, resulting in dilacerations, often follows traumatic injury to the primary predecessor. A study by Patiletal, on Indian population reported the prevalence of very rare developmental dental anomalies and dilaceration was found to be only about 0.5% in prevalence. Case details A 9 year old male reported to the department of paediatric dentistry with complaint of missing central incisor in maxillary left arch. Radiographic examination revealed impacted maxillary left incisor with very unique and unusual extreme curve in root of same tooth giving it a characteristic U morphology. As the patient reported in mixed dentition stage, both the surgical, prosthodontic and pedodontic perspectives were kept in mind before planning for the treatment. Surgical removal was planned as it was not possible to save and place the tooth in the arch. Although surgical removal was challenging due to extreme curve and highly placed position of tooth, surgical removal was done successfully with roots and crown broken in two sections in spite of proper care during extraction procedure. Edentulous space was replaced with groper’s appliance considering mixed dentition stage of the patient after successful healing as per the pedodontic perspectives. Conclusion U shaped presentation of single rooted tooth is a one of the rarest findings. In children with age of interception, treatment should be planned wisely taking into consideration surgical, prosthodontic and pedodontic perspectives together.

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.

AbstractAn altered facial appearance is more difficult to face, than problems related to ill-fitting denture or eating. The selection of maxillary anterior teeth for complete denture has long posed problem in clinical practice and a controversy about the best method to employ still exists. An attempt is made in the present study to clinically correlate the face form with maxillary central incisor tooth form in males and females of Davangere population. In 1914, Leon William's projected the “the form method” where he classified facial forms as square, tapering, and ovoid. Maxillary central incisors were selected according to the facial forms.Of total 100 subjects four different tooth forms and face forms were evaluated. They are: square, ovoid, square-tapered, tapered. No significant correlation existed between face form in male and females. Females exhibited greater correlation between face forms and inverted tooth form but that correlation is not sufficient to serve as a guide for selection of anterior teeth.
