Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Objective To acquire high spatial resolution two-dimension pulse pressure distribution for objectifying research of pulse diagnosis in traditional Chinese medicine.Methods A sensor array with flexible packing was designed and implemented.The array was formed on a circle substrate with 37 silicon piezoresistive pressure sensors,which were distributed as equilateral triangles with 1.95 mm pitch.The diameter of the substrate was 15 mm.By using flexible packing,the array had the hardness similar to that of human finger,which made this method closer to the traditional Chinese diagnosis.After differential amplifying,37-way pulse pressure signals were digitalized and reconstructed to obtain the pulse pressure distribution.Results With the application of the sensor array,the pulse pressure signals were measured and transformed into pulse pressure distribution.Conclusions The experimental result contains the relevant characteristics of traditional Chinese pulse diagnosis' description,providing a new way for objective study of traditional Chinese pulse diagnosis and further study.

Objective To develop and test a high precision medical device which allows measurement of bioimpedance in regions below skin surface,and to enable the assessment of strained muscle's situation and instruct patient's rehabilitation exercise.Methods The system was based on the four-electrode impedance measurement mode and designed by using impedance converter network analyzer AD5933 and monolithic operational amplifier AD844.The hardware consisted of an excitation current source,a response signal adjustment circuit,a digital demodulation circuit and a shield driving circuit.This hardware circuit was combined with a LCD screen and a keyboard,which turned it into a portable precision bioimpedance testing device.Results Using an model of three components as test target,a comparison between the device and the Agilent 4294A precision impedance analyzer was presented.In the range of 1 kHz to 100 kHz,the device showed the similar relative error of the complex impedance's modulus and 1 degree absolute error of the complex impedance's phase.The strained muscle's bioelectrical impedance changes in a clinical case during the convalescent were presented and discussed with the results proven to be clinical meaningful.Conclusions The device is accurate,simple and convenient,which is proved qualified on helping doctors to assess the injury states of the strained muscle and to instruct patient's rehabilitation exercise.
