Orthodontic repositioning of traumatically intruded permanent incisors - A report of three cases

Intrusive luxation of permanent teeth is one of the most serious traumatic dental injuries involving damage to the gingival tissue, periodontal ligament, cementum, bone and to the neurovascular supply of the pulp. In addition to disruption of normal tooth development and eruption, it can also lead to pulpal necrosis, root resorption and marginal bone loss. Based on the extent/severity, intrusion maybe classified into mild (<3 mm), moderate (3-6mm) and severe (>6mm). Available techniques for managing intrusive luxation include a wait-and-watch approach to allow for spontaneous re-eruption, orthodontic traction and surgical repositioning. The type of treatment approach employed depends upon the stage of root development, severity of intrusive luxation and the presence or absence of alveolar fractures. It is difficult to predict reliable outcomes with these approaches, since the presence of variables such as the severity of intrusion, associated crown/root fracture, stage of root development and presence of alveolar fractures may alter the prognosis. The present article presents a series of three cases with intrusive luxation of permanent incisors successfully treated using an interdisciplinary approach involving orthodontic traction along with endodontic rehabilitation

Energy analysis and exergy analysis method

We mounted the thermodynamic evaluation model by means of the use of the actual dimension parameters of six hundred MW direct dry cooling strength plant in Wuxiang, China. The overall performance, particularly the exergy losses of the unit in addition to its subsystems in particular along with seven parts were acquired no longer most effective at one particular load however additionally at specific masses. We’ve determined that the exergy loss inside the boiler is generally greater than 70% of the whole exergy lack of the gadget, while the exergy loss of the combustion occupies more than 50% of that of the boiler. Therefore, it's far critical to lessen the losses inside the boiler for electricity saving capability development, in particular that of the combustion and warmth switch. on the same time, the cold stop optimization has fairly huge capacity for power saving due to that the exergy efficiency of the air cooling device is pretty low being approximately 5.7% or so. in addition, we've got gotten the primary converting traits of gadget performances in conjunction with the weight alternate, together with exergy loss, exergy efficiency and coal consumption, which were derived from the real-time system performance records according to a massive quantity of measured records in actual time. if you want to make the complete device run greater effectively, it's far cautioned that the unit need to run at the load higher than 350 MW

Tooth reattachment: An immediate esthetic restorative procedure for crown root fracture

Crown root fractures in the maxillary anterior region represent an intriguing challenge for clinicians. An interdisciplinary approach based on exposing fractured margins and the definitive prosthetic rehabilitation represent the standard modality of treatment for these conditions to restore the appropriate biologic dimension and esthetics. However, if the margins of the fragment and the tooth show perfect juxtaposition with no interfragmentary space and immediate esthetic replacement is needed, reattachment of the fractured segment using adhesives may be indicated. The aim of this case report is to describe the treatment of a crown root fracture at CEJ of an endodontically treated tooth having porcelain fused to metal crown by means of metal post placement and reattactment of the fragment using Glass ionomer cement with follow up of one year. Conclusion: Reattachment of a tooth fragment is a viable technique that restores function and aesthetics with a very conservative approach in a single visit and can be considered when treating patients with crown/root fractures of the anterior teeth

Dental management of hypohidrotic ectodermal dysplasia: A report of two cases

Ectodermal dysplasia (ED) represents a group of inherited conditions characterized by anomalies in two or more structures of ectodermal origin, which can be presented as problems related to hair, nail, teeth, sweat glands, and sebaceous glands. Based on clinical findings, there are two major types of this disorder: (1) Hypohidrotic/anhidrotic and (2) hidrotic ED. The anhidrotic/hypohidrotic ED (HED) is the more severe form and is associated with more dental defects. This article presents with prosthetic rehabilitation including removable partial and complete denture and implant supported overdenture of two male children of a family presenting with HED

Oral health status of 5 years and 12 years old school going children in rural Gurgaon, India: An epidemiological study

Background and Aims: Oral health is an essential component of health throughout life. Hardly any information is available on the oral health status of children in Gurgaon. Thus, the present study was conducted among 5-year-old and 12-years-old children in schools in rural Gurgaon. Materials and Methods: A total of 1003 children were examined of which 619 were in 5 years age group and 384 in 12 years group. The prevalence of dental caries was studied using dentition status and treatment needs index. For dental calculus criteria of Community Periodontal and for dental fluorosis Dean′s index was used. Results: In 5 years age group prevalence of dental caries was 68.5%, dental fluorosis was 22.5% and treatment needs were 63.7%. In 12 year age group prevalence of dental caries was 37.5%, dental fluorosis was 76.04%, highest community periodontal index score was 2, seen in 80.2% and overall treatment needs were 44.3%. Conclusion: Preventive approaches seem to be a viable alternative to tackle the overwhelming problem of dental caries and other oral diseases. Provision of oral health education in schools and school based preventive programs are important for improvement of this situation

An innovative technique to distalize maxillary molar using microimplant supported rapid molar distalizer

Introduction: In recent years, enhancements in implants have made their use possible as a mode of absolute anchorage in orthodontic patients. In this paper, the authors have introduced an innovative technique to unilaterally distalize the upper left 1 st molar to obtain an ideal Class I molar relationship from a Class II existing molar relationship with an indigenous designed distalizer. Clinical Innovation: For effective unilateral diatalization of molar, a novel cantilever sliding jig assembly was utilized with coil spring supported by a buccally placed single micro implant. The results showed 3 mm of bodily distalization with 1 mm of intrusion and 2° of distal tipping of upper left 1 st molar in 1.5 months. Discussion: This appliance is relatively easy to insert, well-tolerated, and requires minimal patient cooperation compared to other present techniques of molar distalization. Moreover, it is particularly useful in cases that are Class II on one side and Class I on the other, with a minor midline discrepancy and nominal overjet. Patient acceptance level was reported to be within patients physiological and comfort limits

Reverse twin block for interceptive management of developing class III malocclusion

Early correction of developing class III malocclusions remains a complex challenge. Treatment approaches for these young patients have been directed at growth modification. Encouraging outcomes have been reported with the use of Class III functional appliances including reverse twin block (RTB) appliance. The present paper tries to provide an insight into RTB appliance used for successful interceptive management of developing class III malocclusion in two children. RTBs were fabricated with bite registered in the position of maximum possible retrusion of mandible with interincisal clearance of 2 mm and vertical clearance of 5 mm in the buccal segments. Anterior crossbite was corrected, and there was a marked improvement in facial appearance of the children. RTB can be a viable and effective functional appliance treatment modality for early management of developing class III malocclusion
