Summary
Primary double tooth (PDT) affects permanent successors, with prevalence at 0.6% in a Turkish population. Type I PDTs are linked to missing lateral incisors, while Type IV PDTs are associated with supernumerary teeth and caries.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
Background:
- Primary double tooth (PDT) can impact permanent dentition development.
- Understanding PDT prevalence and associated anomalies is crucial for pediatric dental care.
Purpose of the Study:
- To determine the prevalence and types of primary double tooth (PDT) in a Turkish population.
- To investigate the effects of PDT on permanent successors, including dental anomalies and pathologies.
Main Methods:
- Retrospective analysis of 63 PDTs in 54 children from 10,000 patient records.
- Classification of PDTs using Aguilo's classification.
- Statistical analysis using chi-squared tests to assess associations between PDT type and successor anomalies.
Main Results:
- PDT prevalence was 0.6% in the studied Turkish population.
- Type IV PDTs were most common (41.3%), followed by Type III (31.7%).
- Aplasia of permanent lateral incisors was most frequent with Type I PDT (56%); supernumerary teeth were associated with Type IV PDT.
- Caries involvement was highest in Type IV PDT (58.3%).
Conclusions:
- PDT prevalence is 0.6% in Turkish children, with specific types linked to distinct permanent successor issues.
- Type I PDTs are associated with permanent lateral incisor aplasia, and Type IV PDTs with supernumerary teeth.
- Clinical and radiographic assessment is recommended for PDTs, with Type IV PDTs potentially benefiting from sealants.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

2.6K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

01:28Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

01:29Bone Formation by Intramembranous Ossification
15.9K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

01:22Sutures of the Skull
13.7K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
