The severely atrophic maxilla results from advanced bone resorption and becomes a limiting condition for patient rehabilitation. The dental surgeon requires extensive anatomical and technical knowledge to perform major surgical procedures, such as the use of bone grafts and the installation of zygomatic implants. These techniques are, most of the times, procedures that present high morbidity and risks and possible complications. In this perspective, the option for more conservative techniques can favor implantoprosthetic rehabilitation. The purpose of this article was to present the alternative technique of transnasal and pterygoid implantation to avoid the Quad Zygoma, using extralong implants as a new anchorage alternative in atrophic jaws, thus aiding immediate loading. The patient has been under follow-up for 12 months.

One of the most important features of dentistry is its autonomy, based on the sound social contract of respect for the patient’s interest to be given the highest standard of care he/she actually needs and explicitly demands. This did not change during the years of social development since the second half of the 19th century. Paradoxically, today, even the noticeable market character of the dental care provision, under the Covid 19 challenge, we are eyewitnesses of another trait of the dental profession – the growing idea of social service based on the solidarity and understanding of social expectations and trends in public health and public healthcare.

Recently, in Brazil, a case of Nicolau Syndrome was reported due to an alectomy procedure performed by a dental surgeon [1]. Alectomy is the bilateral partial removal of the distal part of the nasal wings, promoting the thinning of the nose. It has been presented as a more conservative proposal in relation to structured rhinoplasty. However, in this procedure, the cartilages that support the nose are also removed to allow air to pass through.

Background: Premature loss of primary molars plays a significant role in the malfunction of the masticatory apparatus and considerable malocclusion. Space maintainers referred to appliances that preserve the space for adequate eruption of permanent teeth. In modern civilization, the era of esthetics has the main interest of people; therefore, the introduction of new materials and techniques is required.
Methods: In the present study, clinical and antimicrobial evaluation of two luting types of cement [(glass ionomer cement (group A) and resin cement (group B)] under custom made zirconia space maintainers.
Results: Twenty-four space maintainers (96%) remain in position and function after three months of evaluation for group A and 92% for group B. Also, there was no significant difference in the antibacterial properties between the two groups.
Conclusion: Both luting types of cement provided a sufficient success rate during the clinical evaluation period.

Introduction
With the presenting of modern technology in our lives, everything became so much easier, faster and the impossible turned to possible in almost every field. This includes the dental field, as before the invention of the great technologies; no one thought that it’s possible to limit too many appointments in the dental office to only one visit.
Digital dentistry is a term that means the use of computerbased or digital components to carry the dental procedures rather than using electrical or mechanical ones.

Endodontic-periodontal lesions or retrograde pulpitis can be caused by the bacteria in periodontal pockets affecting the dental pulp. More than half of all tooth problems are caused by pulpal and periodontal disorders. Inflammatory periodontal disease and pulpal problems might make diagnosis and treatment planning more complex. The efficiency of a bio absorbable barrier membrane in the therapy of a furcation defect linked with an endo-perio lesion in a left mandibular first molar is examined in this case report. The hard and soft tissue lesions have completely healed on follow-up radiographs. For a long-term prognosis, the tooth with endoperio lesions should be extensively examined for any cracks or fractures, particularly in the furcation zones. It was demonstrated in this case study that a three-month treatment interval between endodontic therapy and periodontal surgery has no negative impact on periodontal tissue healing.

Presence of an additional supernumerary distolingual root in the mandibular molar is termed as Radix Entomolaris (RE). It is common in mandibular first molar, but its occurrence in mandibular second molar is scarcely reported in literature. Two-dimensional imaging can diagnose anatomical root canal variations when taken with different horizontal angulations. With the recent innovations in three-dimensional diagnostic imaging, cone beam computed tomography (CBCT) can aid in unfolding the complexities of the root canal system. Accurate diagnosis by CBCT leads to the success of endodontic treatment. A rare case of radix entomolaris in mandibular second molar is reported here with three-dimensional imaging with CBCT.
