Orthodontic-induced external apical root resorption is one of the idiopathic phenomena as an effect, with force generated through mechanotherapy as the cause and the biological tissues with their diversified variations as witness. It is also classified as iatrogenic as a result of indeterminate application of orthodontic forces with subconscious appreciation of the existing underlying conditions. Numerous factors were identified to relate to this irreversible pathologic condition, but none were proven scientifically. Genetics and salivary markers have proved the reliability with time, but the application became insignificant limiting mostly to the research field. Different assessment methods were also identified to clinically diagnose it both subjectively and objectively. Mostly, it is identified through routine radiographic stage records like orthopantomogram or certain prediction radiographs for root resorption probability assessment like in this case. This case report discusses one such encounter which was experienced after stage 1 and 2 mechanics involving quite a few teeth. Considering the biotype of the individual and tooth morphology, the ongoing treatment was terminated and recovery measures were briefed to uplift the self-esteem of the individual. Furthermore, the prognosis is compromised to be very poor with unpredictability to any other treatment modalities.

Cerebral palsy is a neurological and motor condition characterised by muscle balance and posture impairments. Bruxism and malocclusion were frequently observed in patients with cerebral palsy, in contrast to other oral anomalies. The report outlines how severe awake bruxism is managed in a 16-year-old Korean boy who has nonverbal spastic cerebral palsy and global developmental delay. The treatment protocol involved the fabrication of soft occlusal splints of three and four millimetres in thickness, followed by the placement of stainless-steel crowns on all first permanent molars whilst video recording and a bruxism diary was kept. Fixed restorations demonstrate increased endurance in withstanding bruxism force in persons who are dependent on their caretaker.

Fulltext Cosmetic "Gold Thread Therapy": A Nuisance That Decreases the Diagnostic Quality of a Dental Panoramic Image

Ching ME, Joan LZY, Nambiar P

Case Rep Dent, 2021;2021:4077930.

PMID: 34777877 DOI: 10.1155/2021/4077930

During routine imaging of the craniofacial region, it is recognised that some "cosmetic" procedures with metallic insertions can be revealed radiographically. These objects however make it difficult to obtain a good interpretation of anatomical structures for management of diseases. A 58-year-old female patient visited a private dental facility in Kuala Lumpur for prosthodontic replacement of missing teeth. The dental panoramic image revealed generalized bone loss and numerous unusual multiple thread-like radioopacities. These gold threads made radiographic evaluation difficult and complicated the process of treatment planning for dental implant placement advocated for this patient.

Case Rep Dent, 2017;2017:6205925.

PMID: 28932606 DOI: 10.1155/2017/6205925

INTRODUCTION: Plummer Vinson syndrome also known as Paterson Brown-Kelly syndrome is a syndrome associated with the triad of symptoms comprising microcytic hypochromic anemia, oesophageal strictures, and dysphagia. PVS is commonly found in women of middle age especially in the fourth and fifth decade of life and is rarely reported in males.

CASE REPORT: The authors report a case of 43-year-old male patient who presented with the classic symptoms of Plummer Vinson syndrome.

CONCLUSION: Dentists have to be familiar with symptoms of PVS and a thorough clinical examination of the patient is necessary for early diagnosis and treatment. As PVS is a precancerous condition with high malignant potential, early diagnosis is of utmost importance for better prognosis.

CLINICAL SIGNIFICANCE: Mutual interaction of systemic and oral health has largely been underestimated by many patients in the developing countries and hence this report includes a note on importance of adequate medical history taking and its relevance to the dental health and treatment.

Stainless steel alloys containing 8% to 12% nickel and 17% to 22% chromium are generally used in orthodontic appliances. A major concern has been the performance of alloys in the environment in which they are intended to function in the oral cavity. Biodegradation and metal release increase the risk of hypersensitivity and cytotoxicity. This case report describes for the first time a CAD/CAM zirconium bar as a bonded mandibular fixed retainer with 2-year follow-up in a patient who is subjected to long-term treatment with fixed orthodontic appliance and suspected to have metal hypersensitivity as shown by the considerable increase of nickel and chromium concentrations in a sample of patient's unstimulated saliva. The CAD/CAM design included a 1.8 mm thickness bar on the lingual surface of lower teeth from canine to canine with occlusal rests on mesial side of first premolars. For better retention, a thin layer of feldspathic ceramic was added to the inner surface of the bar and cemented with two dual-cured cement types. The patient's complaint subsided 6 weeks after cementation. Clinical evaluation appeared to give good functional value where the marginal fit of digitized CAD/CAM design and glazed surface offered an enhanced approach of fixed retention.

Fulltext Treatment of Extensively Comminuted Mandibular Fracture with the Aid of a Condylar Positioning Device

Case Rep Dent, 2017;2017:2732907.

PMID: 29391956 DOI: 10.1155/2017/2732907

We describe a case of extensively comminuted mandibular fracture that extends bilaterally to the angle of mandible successfully treated with the use of condylar positioning device (CPD). This simple, yet effective, technique that almost exclusively described in orthognathic surgery is useful when advance surgical techniques such as pre- or intraoperative landmark identification may not be readily available. CPD technique optimizes the manual manipulations of the comminuted distal segments during fracture reduction and internal fixation. At the same time, it allows greater control of the proximal segments to avoid further surgical complication.

Fulltext Multiple Cemento-Ossifying Fibroma: A Sign of Hyperparathyroidism-Jaw Tumour Syndrome

Case Rep Dent, 2023;2023:4664619.

PMID: 36937223 DOI: 10.1155/2023/4664619

Hyperparathyroidism-jaw tumour (HPT-JT) syndrome is a rare autosomal dominant disease. It is caused by a gene mutation of the tumour suppressor gene CDC73 that encodes for parafibromin. This syndrome predisposes to a triad occurrence of multiple maxillary or mandibular cemento-ossifying fibroma, parathyroid adenoma or carcinoma, and renal and uterine tumours. In this study, we report a case of HPT-JT occurring in a 30-year-old male patient.

PMID: 31218085 DOI: 10.1155/2019/6810461

Anterosuperior temporomandibular joint dislocation is rare. Manual reduction of such dislocation is difficult especially when treatment is delayed. Therefore, it has an increased likelihood of needing surgical intervention to achieve reduction. The authors report a case of an anterosuperior temporomandibular dislocation in a 19-year-old male following a motor vehicle accident. Difficulties were encountered in reducing the dislocation necessitating surgically assisted reduction. The long-term outcome following management by condylotomy is reported. This present report also reviews the literature regarding the classification and management of this uncommon dislocation.

Fulltext Partial Mandibulectomy Rehabilitation of Keratocystic Odontogenic Tumour Case in Neutral Zone

Restoring the patient's missing dentition secondary to partial mandibulectomy of KCOT is important to improve function and aesthetics. The patient presented with a significant loss of alveolar bone which makes the fabrication of rehabilitation prosthesis a significant challenge. A neutral-zone impression technique is helpful in determining the exact space to be restored without compromising aesthetics and it avoids functional muscle displacement that may displace the prosthesis. This article describes the neutral zone impression technique to record a patient's functional muscular movement in guiding the setting of acrylic teeth and denture flange in the neutral zone area. This technique is very useful for postsurgical cases with significant loss of alveolar bone.

Implant-Retained Obturator for an Edentulous Patient with a Hemimaxillectomy Defect Complicated with Microstomia

Patil PG, Nimbalkar-Patil S

PMID: 27843652

Patient. A 68-year-old man was operated on for squamous cell carcinoma (T3N3M0) of the maxilla creating the hemimaxillary surgical defect on right side. The remaining arch was completely edentulous. There was remarkable limitation in the oral opening with reduced perimeter of the oral cavity due to radiation and surgical scar contracture. This article describes prosthetic rehabilitation by modifying the design of the obturator and achieving the retention with dental implant. Discussion. Severe limitation in the oral opening may occur in clinical situations following the postsurgical management of oral and maxillofacial defects. The prosthetic rehabilitation of the surgical defect in such patients becomes a challenging task due to limited access to the oral cavity. This challenge becomes even more difficult if the patient is edentulous and there are no teeth to gain the retention, stability, and support. Conclusion. In severe microstomia prosthesis insertion and removal can be achieved with modification of the maximum width of the prosthesis. Dental implant retention is useful treatment option in edentulous patients with maxillary surgical defect provided that sufficient bone volume and accessibility are there for implant placement.
