Root resorption is a common iatrogenic consequence of orthodontic treatment, although it can also be seen in the absence treatment. It may occur at any time during treatment and compromise prognosis tooth involved stability results. Orthodontics only branch which actually uses inflammatory process as tool for solving esthetic functional problems. Therefore, every orthodontist should know risk f...

The aim of this clinical and confocal laser scanning microscopic study was to compare the effects of two frequently used archwires on tooth movement and root resorption. A total of 84 premolars in 27 individuals (10 boys, 17 girls, with a mean age of 12.5 years) was moved buccally with an experimental fixed orthodontic appliance. In a split mouth experimental design the premolar on one side was...

OBJECTIVES To assess the accuracy of coronal and sagittal CT sections to detect cavities simulating root resorption. MATERIAL AND METHODS 60 mandibular incisors were embedded in plaster bases, and cavities with 0.6, 1.2 or 1.8 mm in diameter and 0.3, 0.6 or 0.9 mm in depth (small, medium and large cavities) were drilled on the buccal surfaces with high-speed round burs with diameters of 0.6, ...

Q1. In the lingual system, the force to the center of resistance of a tooth is different from that in the labial system. In the present case, the upper incisors tipped lingually after intrusion, as shown in the cepha­ lometric superimpositions. I think that the intrusive force against the upper posterior teeth was applied lingually to the center of resistance, and, therefore, the upper posterio...

Treating pathological defects that are caused by resorption in teeth can be challenging. The task is complicated further if the resorption extends beyond the restrains of the root. The aim of this report is to describe a case of extensive internal tunneling resorption (ITR) associated with invasive cervical resorption (ICR) in a maxillary right lateral incisor and its nonsurgical treatment. A 2...

OBJECTIVES To assess the relationship between periodontal parameters and cervical root resorption in orthodontically moved teeth. MATERIAL AND METHODS In a standardized experimental tooth movement in 16 periodontally healthy subjects, 29 pre-molars were tipped buccally for 8 weeks. Eighteen contralateral pre-molars not subjected to orthodontic movement served as controls. Plaque Index (PI), G...

BACKGROUND Coronal resorption is a coronal degeneration of enamel and dentine in which ultimately the crown is replaced by vascular connective tissue through a defect in the enamel organ of an unerupted tooth. This is also known as pre-eruptive coronal resorption. However, the aetiology of resorption remains unclear. CASE REPORT A 13 years 7 months old Caucasian boy who attended an orthodonti...

The aim of this study was to histologically evaluate and compare the effects of the systemic administration of L-thyroxine (TX) and doxycycline (DX) on orthodontically induced root resorption, Twenty-eight male 50- to 60-day-old Wistar rats were used. Seven rats served as the baseline control. Seven animals received TX (20 μg/kg bodyweight/day) and seven DX (1.2 mg/kg bodyweight/day), by means ...

Root resorption is an unwanted effect of orthodontic tooth movement. Analysis of dentine proteins in gingival crevicular fluid (GCF) is a potentially safer method of quantifying root resorption compared with conventional radiographic methods. This study aimed to identify and quantify the dentine-specific matrix protein, dentine sialoprotein (DSP), released into GCF during physiological root res...

statement of the problem: a major objective of investigators is to clarify the role of metabolites in achievement of maximum tooth movement with minimal root damage during orthodontic tooth movement (otm). purpose: the aim of this study was to determine the effect of administration of thyroid hormone, prostaglandin e2, and calcium on orthodontic tooth movement and root resorption in rats. mater...
