Background: Buccal delivery is an alluring course of organization for fundamental medication conveyance and it leads direct access to the systemic flow through the interior jugular vein sidesteps drugs from the hepatic first-pass digestion gives high bioavailability.
Objective: This article aims at buccal medication conveyance by discussing the structure and condition of the oral mucosa and the novel strategies utilized in evaluating buccal medication ingestion.
Methods: This review highlights the various pharmaceutical approaches for buccal delivery such as buccal tablets, buccal lozenges, buccal micro/nanoparticle, wafer and semisolid dosage forms like chewing gums, buccal patch, buccal gel or ointment and some buccal liquid dosage forms like buccal solutions and buccal sprays and recent patents filed or granted for these approaches.
Results: Recently, some patents are also reported where a combination of various approaches is being employed to achieve very effective mucosal delivery. The various patent search sites were used to collect and analyze the information on buccal drug delivery systems.
Conclusion: The present study provides valuable information, advantages, limitations and future outlook of various buccal drug delivery systems.

Novel Reconstruction Method Using the Double-Arm Vascularized Fibula Flap and TriLock Bridging Plate System for Segmental Mandibulectomy Including the Anterior Border of the Mandibular Ramus.

This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.

Background And Aims: Oral microbiota may contribute to the development of upper gastrointestinal (UGI) disorders. We aimed to study the association between the microbiome of saliva, subgingival and buccal mucosa, and UGI disorders, particularly precancerous lesions. We also aimed to determine which oral site might serve as the most effective biomarker for UGI disorders.

University Hospital for Conservative Dentistry and Periodontology, Medical University of Innsbruck, Innsbruck, 6020, Austria.
Objectives: To compare the plaque reducing efficacy of oil pulling with sesame oil compared to distilled water in a randomized, controlled, examiner-blinded parallel group study.
Materials And Methods: Forty probands without advanced periodontal disease of the University Hospital for Restorative Dentistry and Periodontology, Medical University of Innsbruck (Austria) were randomized allocated to test- (sesame oil) or control group (distilled water) and asked to pull daily in the morning for eight weeks with their allotted fluid for 15 min. Rustogi Modified Navy Plaque Index (RMNPI) and gingival bleeding index were assessed at baseline and after four and eight weeks.

Background: Gingival recession defects (GRDs) pose functional and esthetic concerns and may be associated with unfavorable tooth positions. Surgically facilitated orthodontic treatment (SFOT) with clear aligners can be a valuable option for adults with severe malocclusion and GRDs.
Methods: A 28-year-old male presented with severe dental crowding, Class III dental malocclusion, localized tooth crossbites, and tapered maxillary arch.
