Purpose: The aim of the study is to analyze changes detected in panoramic radiographs due bruxism with qualitative and quantitative scales. Materials & Methods: 173 93 healthy 80 bruxist individuals were included. Maxillary mandibular teeth classified as anterior posterior on radiographs; loss lamina dura (LD), widening periodontal ligament (PDL) space, attrition, presence pulp stones, ...

The roots of two incisors were treated by apicoectomy and a retrograde dentin-bonded composite filling. Periapical healing was observed a few months later by radiography. Later, due to root fracture and marginal bone resorption, the apical parts were removed including adjacent periapical bone. A histological and scanning electron microscopic examination of the tissue showed reformation of perio...

For many years, intentional replantation has been a treatment option for pulpless teeth and an effective strategy for teeth that would be difficult, if not impossible, to treat using traditional root canal therapy. The preservation of cell vitality in the periodontal ligament, the removal of all tissue debris and irritating substances from the root surface, achievement of a good apical seal and...

Missing of mandibular second premolar is one of the most common types of tooth agenesis. In such cases, maintenance of the primary second molar, if possible at all, can prevent many treatment procedures in future. The present case report represents the endodontic management of a necrotic left mandibular primary second molar that had developed an abscess. Considering the missing of the permanent...

In some patients, the permanent central incisors fail to erupt and become impacted within the alveolus. In individuals with unfavorable impactions, surgical replantation may be considered to be a reasonable solution before orthodontic repositioning. In this clinical case report, a 9-year-old male patient presented with the permanent maxillary left central incisor in an inverted position high in...

The aim of this study was the radiographic evaluation of the apical and periapical region of dog teeth submitted to intracanal bacterial endotoxin (lipopolysaccharide, LPS), associated or not with calcium hydroxide. After removal of the pulp, 60 premolars were divided into four groups and were filled with bacterial endotoxin (group 1), bacterial endotoxin plus calcium hydroxide (group 2), salin...

Among a variety of biomaterials that have been reported to be ideal for dental repair, calcium hydroxide has been shown to have excellent long-term biocompatibility in the pulp and periapical areas. Here we report an alternative method employing calcium hydroxide for periapical surgery in a patient who developed internal apical resorption after traumatic injury, which negatively affected the qu...

Patients with Vitamin D-resistant rickets have abnormal tooth morphology such as thin globular dentin and enlarged pulp horns that extend into the dentino-enamel junction. Invasion of the pulp by microorganisms and toxins is inevitable. The increased fibrotic content of the pulp, together with a reduced number of odontoblasts, decreases the response to pulp infection. The most important oral fi...
