Introduction: Mild or moderate-intensity injury will respond with a brief inflammatory response followed by reactionary dentinogenesis. Calcium hydroxide has been considered the gold standard for pulp capping materials for decades to stimulate the formation of tertiary dentin. Blood clamshells (Anadara granosa) contained a high content of calcium carbonate (CaCO3) in the blood clamshells. It is a source of calcium and it has good biocompatibility to be used as a bone repair material. This study is aimed to reveal the expression VEGF-A in odontoblast pulp cells on days 1, 3, and 7 after administration of blood clam shells derived calcium carbonate in dentin pulp complex. Methods: Thirty Wistar rats (Rattus norvegicus) were divided into 6 groups consist of 5 random samples each. The experimental group’s cavity was prepared on the occlusal side of the right upper molar, and they were treated with blood clamshell calcium carbonate suspension and sealed with RMGIC. For decalcification, the solution was replaced with ethylene-diamine tetra acetic acid (EDTA) after 24 hours and was refreshed every day. Anti-VEGF-A monoclonal antibodies were used for HE and immunohistochemical staining. Result: In this study, the results were obtained consecutively on the 1st, 3rd, and 7th day with p> 0.05 for VEGF-A in all groups. Conclusion: The application of calcium carbonate is expected to be an innovative treatment in opening up new pathways for the regenerative dentin process through upregulation of VEGF-A

Clinical evaluation for a successful root canal treatment is assessed by various criteria, which are clinical, histopathological, and radiographical criteria. Therefore, failure of endodontic treatment can be described as a recurrence of clinical symptoms, with the presence of a periapical radiolucency or both. Failure factors in the treatment are frequently related to persistent infection. Conventional endodontic retreatment is indicated for symptomatic previously treated teeth or asymptomatic teeth with inadequately done initial endodontic treatment to avoid potential recurrence. Endodontic retreatment in elderly patients is a great challenge because the clinician has to reassure both the physical and psychological factors of the patient to determine whether to save a tooth or perform an extraction. Some difficulties may also be found in root canal retreatment, including finding the root canal hole or root canal blockage found in parts of the root canal that have not been repaired in the previous treatment. A 60-year-old female patient came with the chief complaint of recurrent pain, and subjective discomfort in the maxillary left central incisor. The patient had anxiety about the dental treatment. The tooth had a history of root canal treatment four months ago. The clinical examination showed a positive response to the percussion test. The radiographical analysis showed a root canal underfilling, 2-3 mm short of length from the apex. The tooth was diagnosed as a previously treated tooth with symptomatic apical periodontitis. Endodontic retreatment was performed based on the patient’s clinical condition and consent, followed by composite restoration. The clinical and radiographic re-evaluation after four weeks of follow-up revealed an excellent condition. This favorable result showed that a conventional retreatment plan of persistent pain on the previously treated tooth in an elderly patient led to progressive healing, and a longer follow-up was advised.

Background: Crown Lengthening is a surgical procedure performed to create a symmetrical gingival line and is carried out to expose necessary additional tooth structure. A short clinical crown occurs as a result of dental malformations, eruption disharmony, and genetic variation. Purpose: The purpose of this case report is to explain the treatment management of Crown Lengthening over the case of diastema closure by indirect veneer restoration. Case: 32 years old female presented with a chief complaint over a space between her anterior maxillary teeth. She wants to rectify her smile. Case Management: The management in this case are preparation of Digital Smile Design (DSD), Crown Lengthening on 11 and 21, and Indirect Veneer on 11, 21, 22. Conclusion: Aesthetical rehabilitation could be attained by an indirect veneer treatment followed by a gingival management which is Crown Lengthening.
