OBJECTIVE To report a case of severe dystrophic calcification in maxillary sinus of a child with liver transplantation and dental organs pigmented by hyperbilirubinemia. CASE DESCRIPTION female patient, 12 years old, with liver transplantation performed at the age of 7 due to extrahepatic biliary atresia (EHBA). The patient was receiving the immunosuppressant tacrolimus (2 mg daily). Intraora...

High systemic levels of osteoprotegerin (OPG) in OPG transgenic mice cause osteopetrosis with normal tooth eruption and bone elongation and inhibit the development and activity of endosteal, but not periosteal, osteoclasts. We demonstrate that both intravenous injection of recombinant OPG protein and transgenic overexpression of OPG in OPG(-/-) mice effectively rescue the osteoporotic bone phen...

Aims: The purpose of this study was to assess the reliability of permanent mandibular canine tooth calcification as an indicator of skeletal maturity in Karnataka population by comparing it with the ossification stages of the middle phalanx of the left third finger and also to compare the sexual dimorphism in the timing of these events. Methods: This study was performed on 100 subjects (50 boys...

The aim of this study was to investigate the relationships between the stages of calcification of various teeth and skeletal maturity stages among Turkish subjects. The samples were derived from dental panoramic and hand-wrist radiographs of 500 subjects (215 males and 285 females). Calcification of the mandibular canines, first and second premolars, and second and third molars was rated accord...

A 32-year-old male patient came to the department of oral medicine and radiology with a chief complaint of discoloured teeth in upper front tooth region since 2 years. He gave no history of pain and a history of fall 4 years ago. Past medical and dental history were noncontributory. Intraoral examination revealed yellowish discoloration of coronal aspect of left maxillary central incisor (Figur...

Public water fluoridation is a common policy for improving dental health. Fluoride replaces the hydroxyls of hydroxyapatite, thereby improving the strength of tooth enamel, but this process can also occur in other active calcifications. This paper studies the effects of water fluoridation during the course of vascular calcification in renal disease. The effect of fluoride was studied in vitro a...

It is well known that exposure to environmental cadmium causes itai-itai (ouch-ouch) disease. However, the exact mechanism underlying this bone disease remains unresolved. By focusing on the calcification mechanism, we examined developing tooth enamel in rats exposed to cadmium to test the hypothesis that cadmium exposure may cause defects in crystal formation. Electron microscopy revealed the ...

In postnatal dental development, and in crown size itself, there is a demonstrable "distance gradient" so that teeth closer together within a jaw quadrant show higher correlations. Thus, adjacent teeth exhibit systematically higher commonality in both tooth formation and crown size than more remote teeth in the same quadrant, despite absolute differences in formation (calcification, root elonga...

Aim: To find out whether a correlation exists among the CVMI and dental calcification stages. Study design: Case-control study Place duration of study: Department Orthodontics, Nishtar Institute Dentistry, Multan from 1st October 2020 to 30th April 2021 Methodology: One hundred fifty orthopantomograms lateral cephalograms patients were incorporated. The maturity was evaluated using8 stages Demi...

Introduction: Age estimation is one of the important issues for treatment planning and determination of patient’s rights in forensic medicine. In spite of various methods which have been introduced for age estimation, there is still no specific practical, non-invasive, and rapid method of age estimation for Iranian population. The aim of this study was to find a precise criteria for age estimat...
