    (Serbian Medical Association, 2019) Tomić, Slavoljub; Davidović, Lado; Božović, Đorđe; Stanojević, Mihael; Cicmil, Smiljka; Tatić, Zoran; Bubalo, Marija; Todorović, Ljubomir
    Introduction The anterior and middle superior alveolar (AMSA) nerve block is an alternative technique of local anesthesia in the maxilla, unpredictably efficient for pulpal anesthesia. The aim of this study was to determine the anesthetic efficacy of the AMSA injection for pulpal anesthesia, using computer-controlled injection system or conventional syringe, and two local anesthetic solutions with or without adrenaline. Methods The authors administered two AMSA injections during two separate appointments, utilizing the computer-controlled system and conventional syringe to 40 subjects, divided into two groups of 20 subjects each depending on the local anesthetic used. A pulp tester was used to test the achieved anesthesia of the central and lateral incisors, canine, first and second premolars, and the first molar in 10-minute cycles over a period of 60 minutes. Duration of anesthesia for all the mentioned teeth was also determined for both the anesthetic solutions and ways of application. Results The AMSA injection with both types of equipment was successful, showing slow onset, satisfying intensity, and declining duration of pulpal anesthesia at the last two measurements. Local anesthetic with vasoconstrictor exhibited a significantly longer pulpal anesthesia. Conclusion The AMSA nerve block could be recommended for achieving pulpal anesthesia of maxillary teeth from the region of the first incisor to the second premolar.

    The Influence of Liners on the Pulp Inflammation
    (Serbian Medical Association, 2015) Davidović, Lado; Ćuk, Mirjana; Živković Sandić, Marija; Grga, Djurica; Živković, Slavoljub
    Introduction The study included application of liners and dental composites in to cavities of six experimental animals – rabbits (Oryctolagus cuniculus). Objective The aim of the study was to investigate rabbit dental pulp response to different liners. Methods Cavity preparation for class V were made on the maxillary central incisors and one lower incisor, while the second lower incisor served as a control tooth. These teeth were restored with the use of one of the following liners – Calcimol LC, ANA Liner and Fuji II LC Improved, and Ceram-X mono dental composite. After an observation period of five days animals were sacrificed and prepared for histological analysis. The existence and degree of the pulp inflammation was determined by using a light microscope. Results Results showed that the used liners do not cause distortion of the structure and continuity of the odontoblastic layer. Inflammation was not registered in the control group, while in each group of tested materials one tooth with mild signs of hyperemia was registered. Results showed that all three tested liners demonstrated favorable effects on the pulp of the tooth and did not lead to inflammatory reactions. Conclusion Histological analysis of the dental pulp of experimental animals suggests that the liners used in this study do not compromise the integrity of the odontoblastic layer, if it is applied over a thin layer of dentin. In each group of tested materials one tooth with mild signs of hyperemia and vasodilation was registered.
