Background: Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiologic development. A delay in time between the exfoliation of a deciduous tooth and the eruption of its permanent successor may be related to a disorder known as dental retention. This occurs when tooth eruption does not occu...

REASONS FOR PERFORMING STUDY There are few published data to support the ages of emergence of permanent dentition widely reported in horses. OBJECTIVES To clarify the chronology and sequence of permanent premolar (PM) tooth emergence in Thoroughbred racehorses. METHODS A prospective study was undertaken in which records were kept of deciduous PM 'cap' extractions performed during routine de...

The regeneration and integration of multiple tissue types is critical for efforts to restore the function of musculoskeletal complex. In particular, the neogenesis of periodontal constructs for systematic tooth-supporting functions is a current challenge due to micron-scaled tissue compartmentalization, oblique/perpendicular orientations of fibrous connective tissues to the tooth root surface a...

Periodontal diseases result in destruction of periodontal tissues, including cementum, bone and periodontal ligament, with eventual loss of tooth if left untreated. Various studies and clinical investigations have resulted in improved therapies for the arrest of disease progression and regeneration of periodontal tissues. A key factor for enhancing the predictability of regenerative therapies i...

Purpose Furcation involvement in the molars is difficult to treat, and has been recognized as a risk factor for tooth loss. Although periodontal regenerative therapies, including guided tissue regeneration and various types of bone grafts, have been applied to furcation defects, the effects of these treatments are limited, especially in large class III furcation defects. The purpose of this pil...

Tooth avulsion represents 0.5-16% of traumatic injuries. Avulsion of a pre-eruptive left permanent maxillary incisor in a 6-year-old boy is presented. The immature tooth was replanted after rinsing with saline following 10 min dry extra-oral time. This case report describes treatment and a 2-year follow-up of the tooth. During the follow-up period, continuation of root development, pulp revascu...

This study examined tooth size in a sample of thirty Northern Irish people with bimaxillary dental protrusion. The mesiodistal diameters of all permanent teeth (excluding second and third molars) were measured. The tooth sizes were compared with a control group who did not have bimaxillary dental protrusion. The results revealed that, on average, tooth size for the overall maxillary and mandibu...

OBJECTIVE To evaluate the correlation among nutritional status, tooth wear and quality of life in Brazilian schoolchildren. DESIGN The study followed a cross-sectional design. Nutritional status was measured via anthropometry using BMI and tooth wear was measured using the Dental Wear Index; both these assessments were carried out by a trained recorder according to standard criteria. A modifi...

Proper occlusion depends on the correct width ratio between upper and lower teeth, known as Bolton's ratio. In fact, this ratio can be calculated for each pair of teeth from the central incisor to the first permanent molar. This set of ratios, known as comprehensive cumulative percentage ratios (CPRs), can be used not only to determine which tooth or teeth have a tooth width discrepancy, but ca...
