OBJECTIVES To study occlusal wear of anterior teeth in orthodontic patients retained with different retainers until 5 years post-treatment, and to investigate whether type of retention influences occlusal wear. MATERIAL AND METHODS Orthodontic patients (n=222), aged 15 years maximally at the start of treatment, were followed until 5 years post-treatment. In the maxilla, a retainer bonded on a...

: Intrusion is the most severe luxation injury, resulting in soft and hard tissue damage. Treatment depends on root development stage tooth intrusion degree. Lateral describes displacement any direction other than axial. The prognosis of luxated teeth emergency treatment elapsed time. This paper reports an 11-year-old boy who sustained central lateral incisors into nasal cavity, his left canine...

OBJECTIVES This study investigates coincidence of the most-prominent point and the mid-point on upper anterior teeth in relation to the use of straight-wire appliances. MATERIALS AND METHODS Alginate impressions of the upper jaw were obtained from forty Caucasian patients. Impressions were cast using hard dental stone. The teeth on each upper study model (canine to canine) were marked along t...

AIM The purpose of this study was to evaluate whether the open apex measurements of the lower teeth can be used for prediction of the pubertal growth spurt. MATERIALS AND METHODS The study group consisted of 150 males and 142 females ranging in age from 10 to 16 years. A total of 292 panoramic and 292 hand-wrist radiographs were obtained and analyzed. The skeletal maturity was determined acco...

Background: Maxillary canines are considered as the keystone of mouth. It plays main role in supporting upper lip and biting tearing food. Canines also called cuspids, one is second most common teeth. The purpose this research was to find pattern prevalence maxillary canine. Study design: a retrospective study conducted for duration six months from April 2022 September at dental department Kara...

This research used the spectroradiometer (Pritchard Model 1980 B) to measure the spectral radiance factors of women's maxillary anterior teeth. The following conclusions were reached: 1. The spectral distributions of the anterior teeth were all similar at the cervical, middle, and incisal areas respectively. Their spectral distributions ran in parallel at an almost equal distance, with the curv...

INTRODUCTION Complete knowledge of root canal curvature is a critical factor in successful endodontic treatment. The aim of this study was to investigate the direction, radius and degree of curvature of maxillary anterior teeth and the relationship between the radius and degree of curvature in Babol, a northern city of Iran. MATERIALS AND METHODS A total of 242 radiographs of maxillary anteri...

BACKGROUND One of the major hurdles in clinical prosthodontics has been the selection and replacement of maxillary anterior teeth in the absence of pre-extraction records. The aim of this study was to determine if a relationship exists between intraoral and extraoral facial measurements that could assist dental practitioners in selecting esthetically appropriate maxillary anterior teeth in the ...

The maxillary canine is second only to the mandibular third molar in its frequency of impaction. The prevalence is about 1.5% and the canine becomes ectopic more often palatally than buccally with over double the frequency. Management of this condition often faces general dental practitioners and orthodontic specialists. Mismanagement and failures in diagnosis may be costly in terms of clinical...

Gingival clefts adjacent to the maxillary canine teeth present a challenge to the veterinary dental surgeon. Periodontal disease results in loss of attached gingiva resulting in periodontal pockets and/or gingival recession. Recession can extend apically toward or beyond the mucogingival margin resulting in clinical exposure of the root surface and subsequent cleft formation. A lateral sliding ...
