Since the day of initial description of calcifying odontogenic cyst (COC), it has remained a subject of considerable interest due to uncertainties surrounding its biological nature—whether it represents a true cyst, a neoplasm, or a cystic neoplasm—as well as its diverse histopathological presentations. Thus, different classifications have been proposed since the day of its inception to justify its biological nature and variable histopathological presentations. The aim of this article was to discuss series of cases of simple COC, COC associated with odontoma and Dentinogenic ghost cell odontogenic tumor (DGCT) which corresponds to Praetorius classification type 1, 2 and 3 respectively. Further, review of literature is also discussed regarding different nomenclature and classifications proposed.
Background: Mandibular knife-edge residual ridges present a significant challenge during complete denture impression making because of their narrow morphology and susceptibility to tissue distortion under pressure. This report describes the clinical application of the novel Sikri’s Magnetic Attachment Retained Two-Tray (SMART) impression technique, conceptualized, developed, and patented by Dr. Arpit Sikri (Patent/ROC No. L-156844/2024), for obtaining an accurate mucostatic impression of a mandibular knife-edge residual ridge without the application of manual finger pressure. The SMART technique employs a magnetically retained split custom tray design that facilitates pressure-free tray stabilization and precise impression making in anatomically challenging mandibular residual ridges. Materials and Methods: A completely edentulous patient with a pronounced knife-edge residual ridge in the anterior mandible was rehabilitated using the SMART impression technique. A custom-designed split two-part impression tray incorporating magnetic attachments for self-retention and retentive holes for impression material retention was fabricated. Magnetic attraction between the tray components ensured stable and reproducible tray positioning throughout the impression procedure, eliminating the need for operator-applied finger pressure and facilitating a pressure-free mucostatic impression of the residual ridge. Results: The SMART technique enabled accurate recording of the mandibular residual ridge anatomy without observable tissue displacement during impression making. The definitive impression produced a well-adapted master cast, resulting in a complete denture with satisfactory retention, stability, adaptation, and patient comfort during clinical evaluation. Conclusion: The SMART impression technique represents a simple, innovative, and clinically applicable approach for the prosthodontic management of mandibular knife-edge residual ridge. By eliminating manual tray stabilization and minimizing tissue displacement during impression making, it facilitates accurate mucostatic impressions and may improve denture fit, stability, and overall clinical performance. Further clinical studies involving larger patient populations are required to evaluate its reproducibility and long-term clinical effectiveness.
Odontogenic space infections can progress rapidly, leading to serious complications such airway obstruction, sepsis, or multi-organ dysfunction. Acute phase reactants (APRs), such as total leukocyte count (TLC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum procalcitonin (PCT), are key markers of inflammation used to assess the severity of infection and monitor treatment response. This study evaluates these biomarkers in patients with odontogenic space infections and their correlation with clinical outcomes. To assess preoperative and postoperative levels of TLC, ESR, CRP, and PCT to determine infection severity and the effectiveness of antibiotic therapy in patients with odontogenic space infections.Methods: This study included 32 patients diagnosed with odontogenic space infections requiring incision, drainage, and tooth extraction. Blood investigations including TLC, ESR, CRP, and serum procalcitonin were performed preoperatively and postoperatively Postoperative CRP levels showed a significant reduction from 58.2 ± 28.1 to 26.2 ± 14.3 mg/L. ESR and TLC levels also demonstrated a significant decline following treatment. Serum procalcitonin levels showed a downward trend postoperatively. Receiver operating characteristic analysis, performed between sepsis and non-sepsis groups, demonstrated variation in diagnostic performance, with procalcitonin showing higher discriminatory ability (AUC 0.956), whereas CRP, ESR, and TLC showed lower discriminatory values (AUC approximately 0.46). Serum procalcitonin demonstrated notable discriminatory performance in the assessment of sepsis. Further studies with larger sample sizes are recommended to validate these observations and explore the role of emerging biomarkers in sepsis.
Context:Esthetics are in high demand in modern dentistry; conservative dentistry offers tooth-colored restorative materials; however, drawbacks such as polymerization shrinkage can lead to microleakage. To minimize this problem, cavity liners are used. Aim:To compare the marginal adaptation and microleakage of different cavity liners under composite restorations using field emission scanning electron microscopy (SEM) and stereomicroscope, respectively. Subjects and Methods:Sixty extracted human premolars and molars were collected, and Class II cavities involving the distal and occlusal surfaces were prepared. The samples were randomly divided into four groups: Group I - Biodentine, Group II - Resin Modified Glass Ionomer Cement (RMGIC), Group III - Resin-modified calcium silicate (TheraCal LC), and Group IV - Direct composite without cavity liner (control). After liner application in Groups I-III, all cavities were etched, bonded, and restored with composite. The teeth were then immersed in 2% buffered methylene blue dye and sectioned longitudinally in the mesiodistal direction. Statistical Analysis Used:Marginal adaptation was evaluated under a stereomicroscope, and interfacial gaps were examined using SEM the Kruskal-Wallis test and post hoc ANOVA (Bonferroni) were used for statistical analysis. Results:TheraCal LC showed the least microleakage, followed by Biodentine and RMGIC, while the control group exhibited significant microleakage. SEM analysis revealed no significant difference between TheraCal LC and Biodentine in marginal adaptation, with the largest gaps observed in the control group. Conclusion:TheraCal LC demonstrated superior performance in terms of both microleakage and marginal adaptation and may be preferred as a cavity liner in Class II cavities.
ABSTRACT Submandibular space infection is a serious odontogenic or oropharyngeal complication that can rapidly extend to deeper fascial planes, leading to airway compromise and systemic sepsis. When complicated by tissue necrosis, management becomes challenging due to extensive soft-tissue destruction, contamination, and impaired healing. Initial management focuses on systemic stabilization with airway protection, intravenous broad-spectrum antibiotics targeting aerobic and anaerobic organisms, fluid therapy, nutritional support, and strict glycemic control in diabetic patients. The primary treatment goals include elimination of infection, thorough debridement of devitalized tissue, and prevention of recurrence. Traditionally, primary closure or free flap reconstruction has been attempted after surgical debridement to achieve rapid wound coverage. However, in actively infected and poorly vascularized fields, such approaches are associated with flap failure, persistent infection, and impaired healing. Secondary healing offers a more biologically favorable and safer alternative. Healing by secondary intention allows the wound to remain open, promoting continuous drainage, reducing reinfection risk, and enabling granulation tissue formation with progressive contraction. This method avoids donor site morbidity, reduces surgical time, and prevents vascular compromise in a contaminated wound bed. In addition, it allows preservation of regional anatomy and close monitoring during the healing process. This case report presents a 50-year-old female with a necrosed wound secondary to left submandibular space infection, managed in the Department of Oral and Maxillofacial Surgery, Punjab Government Dental College and Hospital, Amritsar. Surgical debridement, antimicrobial dressings, and systemic antibiotic therapy resulted in satisfactory healing by secondary intention.
