Summary
Male patients exhibit lower survival rates for transplanted teeth compared to females. This highlights the need for increased attention to male patients during pre-operative evaluation and post-operative follow-up in tooth autotransplantation procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Regenerative Dentistry
Background:
- Gender-related risk factors influencing the long-term survival of autotransplanted teeth with complete root formation remain largely unidentified.
- Tooth autotransplantation is a viable treatment option for missing teeth, but its success can be influenced by various patient-specific factors.
Purpose of the Study:
- To investigate potential gender differences in the survival rates and outcomes of tooth autotransplantation procedures performed in dental clinics.
- To identify if specific genders are more susceptible to complications or failure following tooth transplantation.
Main Methods:
- A retrospective study analyzing data from dental clinics between January 1, 1990, and December 31, 2010.
- Inclusion criteria focused on single tooth autotransplantations in patients with complete root formation, excluding smokers, those with incomplete root development, and patients with fewer than 20 remaining teeth.
- Survival rates were calculated using the Kaplan-Meier method, and differences between genders were assessed using a log-rank test.
Main Results:
- Analysis included 73 male (mean age 47.2) and 106 female (mean age 45.3) patients.
- Females demonstrated significantly higher cumulative survival rates at 5, 10, and 15 years (97.2%, 85.9%, 85.9%) compared to males (88.3%, 64.8%, 48.6%).
- Males experienced significantly more transplanted tooth loss due to attachment loss than females (P < 0.05).
Conclusions:
- Significant gender differences exist in the survival of autotransplanted teeth, with males showing poorer outcomes.
- Males may require heightened attention during pre-operative assessment and post-operative maintenance phases to improve tooth transplantation success.
- Further research into the specific biological or behavioral factors contributing to these gender disparities is warranted.

01:15Teeth
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 and...

01:21Tooth Anatomy
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 grinding food.
