Ankylosis is a condition frequently associated with primary molars, wherein the ankylosed primary teeth remain in a fixed position, while the adjacent teeth continue to erupt, moving occlusally. In this case report, a five-year-old boy, who had a retained and submerged left lower second primary molar, was presented. Luxation of ankylosed primary molar was considered as a treatment approach. Aft...

AIM To describe a pulpotomy with mineral trioxide aggregate in a primary second molar with no permanent successor. SUMMARY Coronal pulpotomy was performed on a carious primary molar with no permanent successor in a 7-year-old child. Follow-up examinations 24 months later revealed that the treatment was successful in preserving the tooth and the vitality of its pulp. KEY LEARNING POINT Miner...

OBJECTIVE To examine the effect of bite force on the displacement and stress distribution of orthodontic mini-implants (OMIs) in the molar region according to placement site, insertion angle, and loading direction. METHODS Five finite element models were created using micro-computed tomography (microCT) images of the maxilla and mandible. OMIs were placed at one maxillary and two mandibular p...

AIM The purpose of this report is to present two cases of totally impacted maxillary deciduous molars, considered a rarity in dental practice. BACKGROUND Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membra...

Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth. The mandibular third molar impaction is said to be due to the inadequate space between the distal of the second mandibular molar and the a...

In this paper, a new method for individual tooth segmentation was proposed. The proposed method is composed of enhancement and extraction of boundary and seed of watershed algorithm using trisection areas by morphological characteristic of teeth. The watershed algorithm is one of the conventional methods for tooth segmentation; however, the method has some problems. First, molar region detectio...

The preservation of deciduous teeth is essential until normal exfoliation. It plays an important role in preventive and interventional dentistry. Early loss a tooth or can have various consequences. Space maintainer the intra-alveolar kind advised when second molar lost before eruption first permanent molar. This report discusses modified Willet appliance cases where primary occur prior to mand...

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...

introduction: the aim of this study is to evaluate the effects of low-level neodymium-doped yttrium aluminium garnet (nd:yag) laser irradiation on orthodontic tooth movement and histological examination. methods: eleven male wistar rats (aged 10 weeks) were included. to produce experimental tooth movement in rats, 10 g force was applied to maxillary first molars with nickel titanium closed coil...
