PURPOSE The purpose of this study was to assess the associations between dental treatment in the early primary dentition and later treatment in the primary and permanent teeth. METHODS Delta Dental Plan of Michigan insurance claims data on 9,886 children who were born in 1990 and were covered by dental insurance from 1990-1998 were used. Risk ratios (RR), screening test measures of sensitivit...

The aim of this study was to carry out a review of the use and efficiency of preformed metal crowns (PMCs) for primary and permanent molar teeth. A literature search of English language journals was carried out using MEDLINE. Papers that addressed areas related to the use of PMCs regarding indications for use, placement techniques, risks, longevity, cost effectiveness and utilization were inclu...

Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...

Supernumerary teeth are among the most common dental anomalies affecting the primary and permanent dentition. They are usually found in the anterior maxilla and occur infrequently in the primary dentition. The purpose of this paper was to report a case diagnosed with primary supernumerary tooth in the primary second molar region. The crown and root shape of the primary supernumerary tooth resem...

Background and aims. Due to anatomic variation in tooth anatomy between populations, this study compared the buccolingual (BL) and mesiodistal (MD) dimensions of primary molars with those of stainless steel crowns (SSCs) in anIranian population. Materials and methods. Impressions were taken from both dental arches of children, and casts were poured. Teeth with caries, restoration, hypoplasia or...

AIM The objective of this study was to compare the effects of ferric sulphate (FS) to that of the full strength of formocresol (Buckley's formula) (FC) as pulpotomy agents in primary human molar teeth 42-48 months after treatment. This was to assess the succeeding premolar teeth for decalcification, abnormal morphology or any other defect. METHODS Seventy children, ranging in age from 3 to 6 ...

Proximal restorations in primary molars were assessed according to surface, teeth affected, and the need for subsequent follow up. All primary molars demonstrated a similar incidence of proximal surface restorative intervention, but the distal surface of the first primary molar and the mesial surface of the second primary molar showed the highest incidence of proximal restorations. The patient'...

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...

introduction: comparison of the relationships and distance between maxillary root tips and   the maxillary sinus floor using oral panoramic in the dolichocephalic and brachycephalic compared to mesocephalic individuals. methods: oral panoramic images from 300 individuals were analyzed and the relationships and distance between the maxillary root tips and the sinus floor was assessed by qualitat...
