“…However, the ultrasonic technique has been widely analyzed within the area of endodontics relating to the removal of fractured posts [ 38 , 39 ] and NiTi alloy endodontic rotary files that can provide useful information in the field of implantology. In the literature, it is stated that the type of ultrasound device, ultrasound power setting, tip geometry, dentin thickness, and canal configuration can affect the temperature rise during post removal [ 40 ]. However, ultrasounds may lead to a temperature rise which can also impact on the surrounding periodontal tissues [ 41 ].…”

“…In addition, Satterthwaite et al showed that most of extracted teeth (46/60) submitted to endodontic post removal exceeded 47 °C of temperature after 5 min of ultrasonic vibration [ 42 , 44 ]. Additionally, Huttula et al concluded that the ultrasonic vibration increases the temperature over 47C which irreversible bone damage may occur, even though a heat sink was used [ 40 , 42 , 46 , 47 ]. Furthermore, reported that the application of a ultrasonic thechnique without irrigation for endodontic post removal for 4 min generated enough heat at the root surface to potentially affect the adjacent teeth [ 48 ] However, Gooty et al recommended the use of an ultrasonic scaler to successfully remove a fractured abutment screw by creating a 1 mm depth hole in the occlusal surface of the fractured abutment screw by a round bur, followed by placing the tip of the scaler in this slot to further unscrew the fractured abutment screw [ 49 ].…”

The aim of this work was to analyze and compare the removal capability, conical internal hex implant-abutment connection damage and thermal effect using ultrasonic and drilling techniques for the extraction of fractured abutment screws. Twenty abutment screws were randomly fractured into twenty dental implants and randomly extracted using the following removal techniques: Group A: drilling technique without irrigation (n = 10) (DT) and Group B: ultrasonic technique without irrigation (n = 10) (UT). The dental implants were submitted to a preoperative and postoperative micro-computed tomography (micro-CT) scan to obtain a Standard Tessellation Language (STL) digital file that determined the wear comparison by morphometry. Moreover, the thermographic effects generated by the DT and UT removal techniques were registered using a thermographic digital camera. Comparative analysis was performed by comparing the volumetric differences (mm3) between preoperative and postoperative micro-CT scans and thermographic results (°C) using the Student t test. The DT extracted 8/10 and the US 9/10 abutment screws. The pairwise comparison revealed statistically significant differences between the volumetric differences of postoperative and preoperative micro-CT scans of the DT (− 0.09 ± − 0.02mm3) and UT (− 0.93 ± − 0.32mm3) study groups (p = 0.0042); in addition, the pairwise comparison revealed statistically significant differences between the thermographic values of the DT (38.12 ± − 10.82 °C) and UT (78.52 ± 5.43 °C) study groups (p < 0.001). The drilling technique without irrigation provides a less removal capability, less conical internal hex implant-abutment connection damage and less thermal effect than ultrasonic technique for the extraction of fractured abutment screws; however, the ultrasonic technique resulted more effective for the extraction of fractured abutment screws.

“…The focusable lens allows adjusting the resolution of the thermographic image based on the distance between the operator and the subject examined. Contrary to what is possible with traditional thermal imaging cameras, in this case, it is not possible for the operator to be placed in a different room from the subject examined [13,[21][22][23], so considering the purposes of the measurements, it is extremely important that the detector operator is adequately distant and protected.…”

“…The thermal sensor and the field of view are comparable to those of more professional thermal imaging cameras [23] and thermal scan used for body temperature detection where the range of detectable temperatures and distance of examination is much smaller. Our results did not show significant differences in body temperature values in males and female subjects independently from the detection of temperature devices and this is in disagreement with another thermographic study on children where girls showed slight upper values of body temperature compared to young boys recorded at rest and after work out [32].…”

“…Thermography has various applications in assessing many dental conditions: temporomandibular joint disorders, chronic orofacial pain, inferior alveolar nerve deficit, pulpal thermal damages, herpes labialis prodromal phase, surgery of impacted teeth [21][22][23][24]. Among the various types of thermographic analysis (infrared, liquid crystals, microwave), infrared thermography is the most used in the medical and dental field.…”

Objective: To evaluate the reliability of infrared (IR) thermal camera connected to smartphones, already used in medicine for diagnostic purposes, as an easy tool for access screening to pediatric dentistry services. Material and Methods: After the preventive telephone triage, thirty orthodontic patients (7-13 years) underwent temperature measurement in the office with two no-contact IR devices: forehead digital thermometer and thermal-camera connected to a smartphone (reference areas: forehead, inner canthi, ears). Measurements were compared and differences were statistically investigated with T student's test (p<0.01). Results: Forehead digital thermometer temperatures were superimposable to those recorded in ear areas and inner canthi with the thermal camera connected to a smartphone. Differences were not statistically significant even in comparison between the sexes. Forehead temperature values detected with a thermal camera are lower than those detected with a digital forehead thermometer. Conclusion: Thermal camera on a smartphone could be reliable in measuring body temperature. Mobile thermographic values of ears and inner canthi areas can be used as an alternative to forehead digital thermometer measurements. Further applications in pediatric dentistry of thermography on smartphones should be examined.

Temperatures of different face regions of healthy people measured by a thermal camera

Body temperature is an important indicator that may indicate the possibility of the existence of various pathological conditions and diseases. In the head and neck area, an infrared camera allows accurate temperature measurements of all regions of interest. The analysis of temperature characteristics of the region of interest of the head and neck in healthy subjects in terms of comparison of values in relation to the side of the face in the same person, and the comparison of values relative to the sex of the subjects is the topic of this research. These analyses are performed to create temperature maps of the face and determine physiological values. The research was conducted with the participation of 30 healthy people, 16 women and 14 men of different ages. Thermal imaging was performed in controlled conditions with infrared thermographic camera Varioscan 3021ST, while the software package IRBIS Professional 2.2 was used for thermogram analysis. Results show that the temperatures in female subjects at the submandibular region are significantly lower than in male subjects with an average temperature difference of 0.46?C, and the temperatures in female subjects at the supraorbital region are on average 0.5?C higher than in male subjects.
