Xerostomia Induced by Radiotherapy: A Review
Xerostomia, or dry mouth, is a common and distressing side effect of radiotherapy in patients with head and neck cancer. Radiation therapy, while effective in tumour control, inadvertently damages salivary gland tissues, leading to reduced salivary flow and altered composition. This article reviews the anatomy and physiology of salivary glands, mechanisms of radiation-induced glandular dysfunction, clinical implications, and contemporary preventive and therapeutic strategies.
Ameloblastoma Disguised As Dentigerous Cyst: A Case Report
Ameloblastoma is a, benign but locally aggressive odontogenic tumor that often presents as a painless swelling in the jaw. Unilocular ameloblastomas often present with features mimicking dentigerous cysts, leading to misdiagnosis. The differentiation between ameloblastoma and dentigerous cyst is critical, as conservative management of a dentigerous cyst may not be sufficient for ameloblastoma. Histopatholical confirmation is essential for distinguishing these lesions and determining appropriate treatment, which may range from conservative enucleation to radical resection, depending on the lesion's size and aggressiveness. This report describes a case of ameloblastoma mimicking a dentigerous cyst in a young adult, emphasizing the importance of histopathological examination for accurate diagnosis and appropriate management.
Optimizing Dental Restoration: Crown Fragment Reattachment With Laser Gingivectomy & Hemostasis: A Case Report
Dental trauma often results in crown fractures, necessitating immediate attention to restore both function and aesthetics. This case report details the successful reattachment of a fractured crown fragment using advanced techniques including gingivectomy and laser hemostasis. To enhance the outcome, gingivectomy performed to optimize the gingival margin, and laser hemostasis was employed to achieve precise tissue management and optimal healing. The patient experienced satisfactory functional and aesthetic outcomes with no complications during follow-up. This case highlights the effectiveness of combining modern dental techniques for optimal restoration outcomes.
Inside the Oral Landscape: Exploring Pyogenic Granuloma's Intricacies
Pyogenic granuloma (PG) is a common benign vascular lesion of the oral cavity, often misdiagnosed due to its clinical resemblance to other lesions. Here, we present a case of a 28-year-old female with a gingival lesion presumptively diagnosed as PG. The management strategy involved a multidisciplinary approach including oral hygiene instruction, scaling and root planing, surgical excision and gingivoplasty. Histopathological examination confirmed the diagnosis of PG. Follow-up assessments demonstrated successful resolution of the lesion without recurrence over a 2 year period. This case highlights the importance of accurate diagnosis and appropriate management of PG to achieve favorable outcomes. Conclusions: This case highlights the importance of a comprehensive approach to diagnosing and managing pyogenic granuloma (PG). By combining clinical assessment, histopathological examination, and personalized treatment strategies, clinicians can achieve successful outcomes while minimizing the risk of recurrence. Further research is needed to refine treatment approaches and deepen our understanding of PG's underlying causes. Through ongoing collaboration and evidence-based practices, healthcare providers can enhance patient care and outcomes for individuals affected by PG.
Pterygoid Implants for Rehabilitation of Posterior Atrophic Maxilla
Aim: The aim of this systematic review is to evaluate the survival rates of pterygoid implants in patients affected by severe atrophy of the posterior maxilla. Materials and methods: A total of 133 articles were found by searching through electronic databases like pubmed, google scholar, science direct, research gate, springer open, Cochrane library, semantic scholar. On further screening of articles for title, abstracts and on application of exclusion criteria, 62 articles were selected. 58 potentially relevant articles were removed after removal of duplicates. 4 articles were taken for the final systematic review after applying the inclusion criteria. Results: A total of 288 patients were rehabilitated 1,357 pterygoid implants. The range of follow-up varied from 3 years to 10 years. The mean cumulative survival rate calculated was 97.08%. Mean diameter of implants used were 4mm. Majority of implants varied in length of 13mm to 20mm. A total of 73 implants failed, before loading from a lack of osseointegration. All the implants analysed in this study had mean bone loss of 1.3mm (21.66%). Conclusion: This systematic review suggests that, pterygoid implants are a magnificent and viable alternative to other posterior implants of the maxilla, especially in cases of atrophy. It offers a series of advantages such as: excellent posterior bone support without the need for bone grafts, reduction of pain and morbidity in the postoperative period, high biomechanical stability, high survival rate and their minimal intraoperative and postoperative complications and good acceptance by patients.
Patient Specific Implant in Postmucormycosis Maxillectomy Patient - Review Article
Rhino-maxillary mucormycosis, leads significant consequences for affected individuals, especially in post-maxillectomy cases where extensive bone and soft tissue loss occurs. The COVID-19 pandemic further exacerbated the prevalence of this infection. while surgical intervention combined with antifungal therapy remains the cornerstone of mucormycosis management, the resulting maxillofacial defects severely affect function, aesthetics, and overall quality of life. Traditional reconstruction methods often fall short in addressing these complex rehabilitative needs. Development of Patient-Specific Implants offer a promising alternative, ensuring better anatomical fit, improved functional outcomes, and reduced surgical burden.
Surgical Sequence for Management of Panfacial Fracture A Systematic Review
Aim: To evaluate and analyse the various sequencing strategies for the surgical management of panfacial fractures. Materials and Methods: A comprehensive electronic and manual search of the literature, without date or language restrictions, was performed across several databases, including PubMed, SCOPUS, SpringerLink, EBSCO, and Google Scholar, 2011 to 2023. The search terms used were "panfacial fracture," "sequencing," "maxillofacial fracture," and "sequence of fixation." Results: A total of 2820 studies were initially identified through database searches, of which 280 studies were shortlisted after title and abstract screening. Following full-text assessment, 13 studies met the inclusion criteria, comprising 676 participants (388 males, 288 females). Among the included studies, 1 study exclusively used the Top-to-Bottom approach, 2 studies focused on the Bottom-to- Top approach with an emphasis on Occlusion First, 4 studies combined the Bottom-to-Top and Outside-In approaches, and 6 studies employed a comprehensive strategy, integrating both the Bottom-to-Top & Outside-In as well as the Top-to-Bottom & Inside Out approaches. The follow-up period varied from 3 weeks to 24 months. Conclusion: This systematic review highlights the variability in surgical sequencing strategies for panfacial fracture management, with the Bottom-to-Top and Outside-In approach being the most commonly used and demonstrating superior outcomes compared to other sequencing patterns. While Top-to-Bottom, Inside-Out, and Occlusion First approaches also yielded favorable results, evidence suggests that the Bottom-to-Top and Outside-In sequence achieves better functional and aesthetic outcomes. Early repair is recommended for optimal reduction and fixation; however, in cases with life-threatening injuries, delayed intervention may be necessary. Complications are observed across all sequencing methods but can be minimized with definitive treatment planning and a stepwise surgical approach.
Role of Different Rigid Fixation in Stability after Bilateral Sagittal Split Osteotomy Advancement Surgery: A Systematic Review
Bilateral sagittal split osteotomy (BSSO) for mandibular advancement is the treatment option for mandibular retrognathia. Major concern in the surgical correction of skeletal class II is postsurgical relapse. The etiology of relapse is multifactorial, involving the proper seating of condyles, the amount of advancement, the soft tissue and muscles, the mandibular plane angle, the remaining growth and remodeling. Through the use of the modern metal plates and screws after osteotomy, the stability can be already achieved in a technique so-called "rigid internal fixation" (RIF), without using "intermaxillary fixation" (IMF). RIF methods contribute to postoperative bone healing and masticatory function. Furthermore, using RIF method, instead of intermaxillary rigid fixation, can initiate the early improvement of oral hygiene. Usually bicortical bone fixation screw or miniplates with monocortical bone fixation screw were used to gain stability after BSSO. On the other hand, the use of resorbable screw materials had been reported. Here we presented a systematic review on Role of different rigid fixation in stability after bilateral sagittal split osteotomy advancement surgery and concluded that bicortical screws (stainless steel, titanium, bioresorbable) and miniplates fixation after mandibular advancement there is no statistically significant difference in skeletal stability and a favourable relationship between the amount of relapse and amount of advancement.
Odontogenic Keratocyct (OKC) Masquerading as Dentigerouscyct: Case Report
Impacted mandibular third molars are commonly associated with pericoronal pathologies. Dentigerous cyst is the most common developmental cystofthejaw. Some of the other pathologies related to impacted teeth are adenomatoid odontogenic tumor (AOT), pindborg tumor, ameloblastoma and sometimes odontogenic keratocyst. Sometimes these pathologies can be differentiated only after histopathological examination. This article presents the case of a 25 year old male patient with complaint of pain in left mandibular posterior region. Clinico-radiographic diagnosis was dentigerous cyst however histopathological report after biopsy was suggestive of Odontogenic keratocyst. Odontogenic keratocysts (OKCs) often occur in the molars in the mandibular ramus, they often progress asymptomatically and are discovered only after widespread development. As the recurrence of OKC is higher than dentigerous cyst so the clinical, radiological and histological features of this tumour along with its surgical management have been discussed.
Facial Harmony Restored: Botulinum Toxin in the Management of Masseteric Hypertrophy - A Case Study
Masseter muscle hypertrophy (MMH) is a benign enlargement of the masseter muscle, often resulting in a square-shaped facial appearance and potential temporo mandibular joint(TMJ) disorders. This case report highlights a 45-year-old Female presenting with TMJ pain, teeth clenching, and snoring Clinical examination revealed bilateral masseter hypertrophy, classified as Type II, prompting a non-surgical treatment approach using botulinum toxin-A (Botox). A six-point injection technique was employed for even toxin distribution, resulting in significant muscle volume reduction and improved facial aesthetics after six months. Additionally, a snoring device was prescribed, successfully reducing snoring and enhancing sleep quality. This report emphasizes the efficacy of the six-point Botox injection technique for Masseter muscle hypertrophy and underscores the need for standardizing this protocol through further research.
Temporo-mandibular Joint (TMJ) Disorders
Unraveling the Puzzle: Pyknodysostosis A Rare Case Report
Pyknodysostosis is a rare autosomal recessive disorder, first described in 1962 by Maroteaux and Lamy. The disorder characterized by the postnatal onset of short limbs, short stature, and generalized hyperostosis along with acro-osteolysis with sclerosis of the terminal phalanges, a feature that is considered essentially pathognomonic. Other features include persistence of fontanelles, delayed closure of sutures, wormian bones, absence of frontal sinuses, and obtuse mandibular gonial angle with relative mandibular prognathism. Here, I present a case having classical features of pyknodysostosis.
Orthodontic and Aesthetic Treatment Integration for Enhancing Facial Profile - A Case Report
This case report discusses the orthodontic and aesthetic treatment of a 35-year-old female patient with forwardly placed upper front teeth, a prominent overjet, and chin fat. The patient's concerns included the appearance of her upper front teeth and submental fullness, affecting her facial profile. Orthodontic treatment was planned to correct the Class II malocclusion, reduce the overjet and overbite, and align the teeth using the MBT appliance. After initial leveling and alignment, space closure was achieved, and the patient's functional goals were met. Additionally, non-surgical chin fat removal via deoxycholic acid injections was performed to address the patient's aesthetic concerns. The case demonstrates the effectiveness of combining orthodontics and cosmetic procedures to enhance both functional and aesthetic outcomes. The patient was satisfied with the results, highlighting the importance of a comprehensive approach to treating malocclusions and esthetic issues. However, the case also underscores the need for thorough treatment planning to ensure long-term success.
First described in 1948 by Ackerman, Verrucous carcinoma is a distinct form of Squamous Cell Carcinoma. It is an unusual and non-metastasizing tumour with a tendency for local invasion in comparison to squamous cell carcinoma. The most common site of occurrence is the buccal mucosa, followed by the mandibular alveolar ridge and gingiva. Slowly growing. well differentiated, verrucous in character, and often extensive, this neoplasm tends to invade local structures like mandible, soft tissues and antrum. Treatment of verrucous carcinoma is challenging; multiple medical and surgical therapies are often attempted with limited success. For extensive lesions, radical surgery is indicated and often when fixation, or invasion of bone is present, mandibular resection with upper neck dissection is justified.
Surgical Management of Traumatic Temporomandibular Joint Ankylosis: A Case Report
The complex disorder known as temporomandibular joint ankylosis (TMJ) affects nutrition and jaw function. Treatment options for post-traumatic joint ankylosis include a range of surgical methods. But no common procedure can ensure a successful outcome devoid of symptoms. Thus, treating TMJ injuries following trauma continues to be a difficult challenge for oral and maxillofacial surgeons. This paper is a case of a post-traumatic TMJ ankylosis. The 31-year-old young man sustained from many facial bone fractures, including condyles, in a car accident seven years ago. The condyle being treated conservative and the maxillary and malar fractures and mandibular parasymphysis was, treated with mini bone plates in other institution 7 years ago. After the surgery, he began to observe a gradually reduced mouth opening. (10mm) and further physiotherapy exercises was unable to restore normal mouth opening of the jaw. Preoperative CT revealed unilateral bony ankylosis on the right side of TMJ. Conservative treatments failed to restore normal jaw movement. An arthroplasty was carried out. The follow-up course went smoothly, with a mouth opening of up to 35 mm.

Conclusion: This study found a few differences in practice trends amongst endodontist and other practitioners, but overall, most clinicians followed international norms
Role of Patient Specific Implant in Reconstruction of Post Traumatic Orbital Defects: A Comparative Systematic Review
Background: Maxillofacial injuries of middle third of the face commonly involves the orbital skeleton and range from the subtle blow-out fracture following simple blunt or low-velocity trauma to the highly complex orbital communication resulting from motor vehicle accidents and projectiles, such trauma to the orbit and surrounding facial structures often leads to orbital deformity and incapacitating visual dysfunction We performed a systematic review to evaluate the role of patient-specific implants in orbital reconstruction and to compare it with conventional reconstruction methods with respect to operative time, orbital volume reconstitution, enophthalmos and diplopia. Material and Methods: A literature search was conducted using the English-language databases EMBASE, MEDLINE, PUBMED and the COCHRANE LIBRARY, as well as local databases containing publications from 2006 to 2022. Results: fourteen studies (n=737 patients) met the inclusion criteria. Overall, the use of patient specific implants for the orbital repair when comparing with conventional in terms of intra operative duration, post-operative orbital volume difference and enopthalmos, however in terms of presence of post- operative diplopia there is no significant difference in either. Conclusion: Patient specific implants are easy to manipulate, insert and anchor. They accurately reproduce orbital contours thus restoring orbital volume. This leads to reduced operative time and an improvement in functional and aesthetic outcomes of post-traumatic orbital reconstruction.
Comparison of Surgical Outcomes of Transoral Robotic Surgery and Conventional Surgery in Oropharyngeal Carcinoma
Background: Transoral robotic surgery (TORS) has recently emerged as a surgical technique for oropharyngeal carcinoma. We performed a systematic review to investigate the clinical safety and effectiveness of robotic surgery compared with conventional open surgery in oropharyngeal carcinoma. Material and Methods: A literature search was conducted using the English-language databases EMBASE, MEDLINE, PUBMED and the COCHRANE LIBRARY, as well as local databases containing publications from 2013 to 2020. The outcomes included complications, as well as oncologic, and functional outcomes. Results: twelve studies (n=4802 patients) met the inclusion criteria. Overall, TORS, when compared with open surgery, appears to have better functional results (less hospital time, decannulation) and fewer intraoperative and post-operative complications. There is no significant difference when assessing the oncological outcomes (positive margins, survival rate) when comparing both techniques. Conclusion: Trans Oral Robotic Surgery (TORS) is advantageous over open surgery with the incidence of the complications rate, post operative oncologic outcome, functional outcome in the surgical management of early-stage oropharyngeal carcinoma.
Evaluation of Survival Rates of Dental Implants Placed Using Indirect Sinus Floor Elevation With and Without Bone Grafts - A Systematic Review & Meta-Analysis
Purpose: The aim of this systematic review is to evaluate the survival rate of implants placed using indirect sinus floor elevation with and without bone grafts. Material and Methods: The electronic databases, such as MEDLINE, EMBASE, PUBMED and CENTRAL were systematically and manually searched. Thirteen studies fulfilled the inclusion criteria. The included articles were subjected to quantitative analysis, and Le meta-analysis was carried out. Results: The included studies were of moderate quality, with overall implant survival rate for grafted implant to be 96.50% and for nongrafted implants 97.40% after follow-up period of more than 1 year. This indicated that the osteotome sinus floor elevation technique with or without grafting were both predictable. Conclusion: Within the limitations of the study, it can be concluded that the implant survival rate for grafted and nongrafted maxillary sinus are predictable. And we can assume that there are many other factors affecting the survival rates of dental implants with osteotome sinus floor elevation in grafted and nongrafted implants.
Prosthodontic Management of neurodegenerative diseases in Geriatric Patients.
Neurodegenerative diseases are among the most difficult to treat and destructive diseases in medicine. A heterogeneous group of chronic and progressive diseases, these include Alzheimer's, Parkinson's, and Huntington's diseases. Dentists dealing with patients with any of these disorders face major cognitive, motor, and behavioural problems, as well as dental maintenance. While the treatment of patients with Alzheimer's disorder advanced neurodegeneration remains challenging, increasing knowledge of the aetiology and pathogenesis of these diseases has provided new opportunities and new insights about their treatment needs. Dental treatment in the early stages of the disease is very important and needs to be treated definitively to create a stable oral condition. This can improve quality of life and help reduce dental deterioration in the later stages of the disease when dental treatment can be difficult.
Root Biomodification The Conditioning Concept
A critical step in periodontal regenerative therapy is to alter the periodontitis affected root surface to make it a hospitable substrate, to support and encourage migration, attachment, proliferation and proper phenotypic expression of periodontal connective tissue progenitor cells. So, the Concept of Biochemical modification has emerged as a potential therapeutic approach to the reconstruction of the periodontal unit. One of the important goals in periodontal therapy is to facilitate formation of new connective tissue attachment on the denuded root surface. This type of regeneration is described by the term 'New attachment'. It can be described as embedment of new periodontal ligament fibres on to new cementum previously denuded by the periodontal disease. The periodontium consists of a cell and tissue complex organized into basic components of cementum, periodontal ligament and alveolar bone. The challenge of regeneration is to reconstitute this complex onto the root surface.
PRF Platelet Rich Fibrin: Is It Ready For The Prime Time?
Loss of connected connective tissue and other periodontal tissues is a hallmark of periodontal disease. Platelet-secreted growth factors aid in the development of new tissue and the healing of wounds. AIM The current review sought to shed light on the function and workings of PRF in periodontal regeneration for periodontally compromised teeth. DISCUSSION: The rationale of these technologies is to extract all the elements from patient's own blood sample, which could be used to improve healing by promoting tissue regeneration. PCs have evolved a long way since its introduction in 1954. CONCLUSION: PRF is regarded as an easy and affordable method for effective periodontal regeneration.
Management of Rhino-cerebral mucormycosis followed by rehabilitation
Mucormycosis is an opportunistic fulminant fungal infection, which mainly infects immunocompromised patients. The recent emergence of the Coronavirus Disease (COVID-19) disease had been associated with reports of fungal infections such as aspergillosis and mucormycosis especially among critically ill patients treated with steroids. The recent surge in cases of COVID-19 in India during the second wave of the pandemic had been associated with increased reporting of invasive mucormycosis. In this era of the pandemic, patients with diabetes mellitus are at an increased risk of secondary infections and systemic complications. We report a case of maxillary necrosis by mucormycosis in an uncontrolled diabetic patient to emphasize early diagnosis of this potentially fatal fungal infection. We briefly discuss different disease and review the current concepts in management of mucormycosis. Early diagnosis, administration of systemic antifungals and aggressive surgical debridement followed by rehabilitation with maxillofacial prosthesis can reduce the mortality of this lethal fungal infection.
A recurrent case of unicystic ameloblastoma
Ameloblastoma is a rare, benign odontogenic tumour associated with a high recurrence rate. It accounts for 1% of all tumours of the jaws. The ameloblastoma occurs in three different variants, each with specific implications for treatment and a unique prognosis: solid or multicystic, unicystic, and peripheral. The term unicystic ameloblastoma has been used to describe an ameloblastoma developing within the lining, lumen, or wall of a cyst as well as an invasive ameloblastoma that has a single cystic space rather than multicystic spaces. It accounts for 5-15% of all intraosseous ameloblastomas. Unicystic ameloblastoma has uniquely distinct nature on recurrence as compared to most other varients of ameloblastomas. Lower recurrence rate of unicystic ameloblastoma gives way for conservative treatment rather than the traditional aggressive approach. We report a case of unicystic ameloblastoma of 22 year old female patient.
Prosthodontic Rehabilitation of An Acquired Maxillary Defect In Post Covid Mucormycosis Patient
AIMS: Rehabilitation of a maxillary defect post mucormycosis with obturator MATERIAL AND METHODS: Phycomycetes is the causative agent leading to the deadly fungal infection calle Mucormycosis. Predisposing factors involve patients with uncontrolled diabetes mellitus, immunosuppressive therapy. The survival rate of the patients depends upon how quickly the disease is diagnosed and treated. A patient with surgical removal of partial maxilla due to covid associated mucormycosis reported with a chief complain of regurgitation of fluids and resonance of sound. On examination partial maxillectomy with oro-antral fistula was diagnosed. The patient was rehabilitated with an iterim obturator after 20 days of surgery followed by a definitive obturator after 4 months. CONCLUSIONS: Post-insertion of prosthesis, there was a significant change in clarity of speech and resonance in voice. Improvement in masticatory function and overall well-being was achieved.
UNICYSTIC AMELOBLASTOMA: AN UNCOMMON VARIANT OF COMMON BENIGN TUMOUR, REPORT OF TWO CASES
Ameloblastoma is the common tumor of odontogenic origin. It is a neoplasm of enamel-organ tissue that has not undergone differentiation to the point of hard tissue formation. It is usually unicentric, non- functional, intermittent in growth, anatomically benign and clinically persistent, frequently seen in mandible. A wide range of multicystic ameloblastoma is the most frequent subtype while unicystic ameloblastoma can be considered as a variant of the solid or multicystic. This subtype is considered as a less aggressive tumor with a variable recurrence rate. However its frequency is often underestimated. Here in my case series, I am presenting 2 cases of ameloblastoma, where both of them are having histopathology showing unicystic in nature.
Amelogenesis Imperfecta: A report of two cases
Amelogenesis Imperfecta (Al) is defined as a group of hereditary developmental defects of the dental enamel affecting both primary and permanent dentition. Al is known by various names such as hereditary enamel dysplasia, hereditary brown enamel, hereditary brown opalescent teeth. This defect involves entirely ectodermal components. Al may be inherited in an X linked manner or by autosomal dominant, autosomal recessive, or sporadic inheritance patterns. Witkop and Sauk listed the varieties of Al, based on whether the abnormality lay in reduced amount of enamel (hypoplasia), deficient calcification (hypocalcification), or imperfect maturation of the enamel (hypomaturation). They have also recognized the combined defects of enamel. Treatment planning involves an interdisciplinary approach of periodontal, prosthodontic and restorative treatment.
Fibro-Osseous Lesion: A Diagnostic Dilemma
Fibro-osseous lesions of the craniofacial complex are represented by a variety of disease processes that are characterized by pathologic ossifications and calcifications in association with a hypercellular fibroblastic marrow element. They are a diverse group of processes that characterized by replacement of normal bone by fibrous tissue containing a newly formed mineralized product. The commonly included fibro-osseous lesions are fibrous dysplasia (FD), cemento-osseous dysplasia and ossifying fibroma. Ossifying fibroma is a true benign neoplasm, whereas Fibrous dysplasia is a genetic developmental anomaly of the bone-forming mesenchyme with a defect in osteoblastic differentiation and maturation that leads to a replacement of normal bony tissue by fibrous tissue of variable cellularity and immature woven bone. The main histologic differences between the two lesions lie in the absence of a capsule and the presence of more immature bone without osteoblastic activity in fibrous dysplasia. Cemento-osseous dysplasia is the most common fibro-osseous lesion affecting the jaw bones.
First described in 1948 by Ackerman, theverrucous carcinoma is an unusual and non-metastasizing tumor with tendency for local invasion in comparison to squamous cell carcinoma. Though it appears remarkably harmless, the histo-pathological diagnosis of verrucous carcinoma should be done. This will help with careful identification of the tumor with a greater chance to become frank cancers. The most common site of occurrence is oral cavity involvingbuccal mucosa and mandibular alveolar crest. Treatment of verrucous carcinoma is challenging, multiple medical and surgical therapies are often attempted with limited success. Here, I report two cases of verrucous carcinoma on lower lip and on buccal mucosa.
Effect of Neutral Soap cleansing on Color Stability of Scleral Acrylic Prosthesis fabricated by Conventional Heat Cure Method and CAD CAM Method: An In-Vitro Study.
