OBJECTIVE To describe the eruption chronology of the first deciduous teeth in premature infants with birth weight less than 1500 g and to compare it according to gender and nutritional status at birth. METHODS Longitudinal study including 40 low birth weight premature infants of both genders. The tooth was considered erupted when the crown went through the gum and became part of the oral envi...

Despite the superb fossil record of the saber-toothed cat, Smilodon fatalis, ontogenetic age determination for this and other ancient species remains a challenge. The present study utilizes a new technique, a combination of data from stable oxygen isotope analyses and micro-computed tomography, to establish the eruption rate for the permanent upper canines in Smilodon fatalis. The results imply...

The aim of this study was to examine the effect of preterm birth on the development of the dentition. The spesific aims were to examine the effect on deciduous and permanent tooth crown dimensions, the eruption of permanent teeth and the sagittal occlusal relationships within the dentition. The subjects consisted of 328 prematurely born (< 37 gestational weeks ) white and black children and 180...

AIM The purpose of this study is the evaluation of the tooth eruption ages in a sample of children aged between 6 and 24 months. MATERIALS AND METHODS The sample consists of 204 children aged between six and twenty-four months, followed up for a period of one year in collaboration with seven pediatricians in the province of Sassari (Italy). The visits were carried out at the paediatricians' p...

An alteration in the path of eruption of teeth or non-eruption is a frequent problem encountered in children. This is mainly seen in the upper incisors giving an unpleasant aesthetic and functional problem. This may be commonly attributed to the presence of a supernumerary tooth. Mesiodens is the most commonly occurring supernumerary tooth present in the premaxilla between the two central incis...

Rabbits (Oryctolagus cuniculus) and rodents possess continuously growing teeth, and dental problems are a major health issue in these species. Knowledge of tooth growth characteristics is required to adequately treat dental problems and advise owners concerning diets. Most research was performed using bur marks and measuring eruption and wear manually. However, this method cannot be applied to ...

The presence of a supernumerary tooth in the nose is an unusual phenomenon and a rare form of ectopic tooth eruption in the maxillofacial region. In this case, the patient was referred to the hospital with the complaint of severe headache. In the endoscopic examination, the supernumerary tooth crown was not covered with mucosa or granulation tissue. In the present study, the clinical and radiol...

Equine dental developmental abnormalities can involve tooth number, morphology, or position in the dental arcades. Abnormalities of dental development and eruption occur quite commonly in the horse and result in a wide range of clinical conditions. Some developmental dental abnormalities of a young horse may not cause the animal to exhibit clinical signs of dental disease until it reaches middl...

Methods of exposing impacted teeth in order to bring them into the line of the arch include gingivectomy, the apically repositioned flap and closed eruption techniques. These procedures aim to facilitate the eruption of the impacted tooth with a minimum of disruption or damage to the tooth itself or adjacent structures. The aim of this paper is to discuss the various surgical methods of exposin...
