In Vivo Pulp Thermal Changes During Different Slenderization Techniques
Sponsor: Armed Forces Institute of Dentistry, Pakistan
Summary
The goal of this study is to learn about the temperature rise inside the living part of a tooth (the pulp) during different ways of removing a small amount of enamel (the hard outer layer of the tooth), a procedure called Interproximal Enamel Reduction (IPR). The goal of this study is to learn about the temperature rise inside the living part of a tooth (the pulp) during different ways of removing a small amount of enamel (the hard outer layer of the tooth), a procedure called Interproximal Enamel Reduction (IPR). The main question it aims to answer is: Which IPR technique causes the highest temperature rise in the live tooth pulp? This study is important because, until now, no research has measured these temperature changes in the live pulp of teeth inside a person's mouth (in vivo) that includes both premolars and front teeth (incisors). The original studies only used premolars, and the results might be different for front teeth due to the difference in enamel thickness. Researchers will use 20 premolar teeth and 20 incisors that will be scheduled for extraction as part of orthodontic treatment. The teeth will be divided into two groups based on the IPR method used: Group 1: IPR using a high-speed air-driven drill (airotor) and bur. Group 2: IPR using an orthodontic IPR kit (an oscillating system). Participants will: Receive local anesthesia to numb the tooth. Have the baseline temperature of the pulp recorded using temperature sensor on either side of the teeth. Have the temperature changes in the pulp recorded using temperature sensor while IPR is performed on the sides of the tooth. Have the tooth extracted afterward (as part of original orthodontic plan) The key findings may provide information of the IPR method that cause a temperature rise high enough to harm the pulp. A rise beyond 5.5∘C may cause pulp damage.

Conditions
Interventions
High-Speed Air-Driven Drill (Airotor and Bur)
This method involves high rotational speed (potentially over 300,000 RPM) and thus has the highest possibility of causing the greatest temperature elevation due to intense friction during interproximal reduction.
Orthodontic IPR Kit (Oscillating System)
This technique operates at a much lower speed (around 5,000 RPM) and is expected to result in a moderate temperature increase, presenting a moderate possibility of thermal effect compared to the high-speed drill during interproximal reduction.
