background and aims. impacted lower third molar is found in 90% of the general population. impacted lower third molar surgery may result in periodontal complications on the distal surface of the adjacent second molar. the aim of this study was to evaluate the effect of flap design on the periodontal status of the second molar after lower third molar surgery. materials and methods. twenty patien...

The orthodontic records of 685 patients referred for surgical exposure of an unerupted impacted maxillary canine tooth were examined. The condition was more common among females than males, slightly less than 2:1. The impacted teeth had a palatal-labial ratio of 3:1. All of the teeth were exposed using the open surgical technique and in 98% of cases the tooth erupted and was orthodontically ali...

The ballista spring system is a simplified orthodontic system for treating impacted teeth. The impacted tooth is retracted by a spring that accumulates a continuous force from being twisted on its long axis. The necessary operation on the impacted tooth is simple and less traumatic. The force exerted on the tooth is vertical, without compressing the impacted tooth toward the adjacent roots. Thi...

BACKGROUND An impacted tooth is one which fails to reach the occlusal plane even after two-third's of its root completion. Though the etiology is multi-factorial, most common reason is crowding of teeth with lack of space for eruption. Mandibular third molars are the most commonly impacted teeth. Very few studies have been done to assess the prevalence of impacted premolar teeth. MATERIALS AN...

This case report presents treatment of a distally impacted mandibular 2nd premolar having a 90° tilt to the long axis of the tooth. In this 16 year old girl radiological finding described that horizontally impacted mandibular second premolar was positioned below the roots of the mandibular first molar. Due to the abnormal position of impacted premolar, it was planned to be removed surgically. F...

objective: the aim of the present study was to histopathologically evaluate follicular tissues of third molars with pericoronal radiolucenciesof less than 2 millimeters. materials and methods: in this descriptive analytic study, 100 impacted third molars with normal follicular spaces were removed and their pericoronaltissues submitted for histopathologic examination. different characteristicsof...

INTRODUCTION Cleidocranial dysplasia (CCD) is a rare inherited skeletal dysplasia, often with prolonged retention of deciduous teeth and several impacted permanent successors and supernumerary elements. METHODS This article demonstrates the usefulness of titanium screws for orthodontic anchorage to induce eruption of the impacted teeth in a patient with CCD. A boy, aged 10 years 11 months, ha...

The prevalence rate of impacted primary teeth is rare, still we can see impacted teeth in ectodermal dysplasia anhydrotic (EDA), endocrine deficiencies, metabolic disorders and local factors like cysts, tumors, trauma and thickened overlying bone or soft tissue. In cases of EDA, delayed tooth eruption is one of the characteristic finding. Present case report related to a rare case of primary te...

The term “impacted teeth” refers to dentition that is partly or completely impacted in bone or soft tissue after eruption should have been completed although eruption age is completed not replaced in dental arc. The most commonly impacted teeth in the anterior region are maxillary canines, while the prevalence of impacted maxillary incisors ranges from 0.06% to 0.2%. Impacted maxillary incisors...

Removal of third molars is a common procedure performed in oral surgery. Although there are well-defined indications for removal of impacted third molars, removal of asymptomatic third molars is still universally practiced. This article reviews the body of knowledge regarding for and against the prophylactic surgical extraction of impacted third molars in contemporary oral surgical practice, an...
