Inflammatory Odontogenic Cysts

Cystic conditions of the jaw cause bony destruction and may cause resorption or displacement of adjacent teeth. Odontogenic cysts have developmental or inflammatory origins. To describe in detail the inflammatory odontogenic cysts, a manual search was done in hard copy books of oral and maxillofacial pathology, and an electronic search was done in the google website, oral and maxillofacial pathology E-books, PubMed, Research Gate, Academia, and Google scholar using the keywords "odontogenic cysts," "classification of the odontogenic cysts," "radicular cyst," "periapical cyst," "lateral inflammatory cyst," "residual cyst," "paradental cyst," "collateral inflammatory cyst," "treatment of inflammatory odontogenic cysts," and matching each odontogenic inflammatory cyst subtype with these words "gross description," "pathogenesis," "microscopical," clinical," "radiographical" appearance. Articles published till February 2021 were included in this review. In conclusion, an accurate diagnosis of an inflammatory odontogenic cyst requires information relative to its clinical, radiographical, macro- and microscopical findings. In many instances, two cysts that are classified differently may exhibit similar histopathological features. In such cases, clinical and radiographic findings are necessary to make a precise diagnosis.

PERIAPICAL CYST IN DENTAL HOSPITAL FACULTY OF DENTISTRY UNIVERSITAS INDONESIA 2018-2019 PERIOD

A periapical cyst is a lesion often found in dental practice. It is an odontogenic cyst of inflammatory origin with an epithelial wall originating from the epithelial rests of Malassez found in the periodontal ligament. Its high prevalence compared to other types of the odontogenic cyst and the absence of recent study of its distribution and frequency based on age, gender, tooth element, position, condition of the involved tooth, and its treatment render the need for further study. A retrospective descriptive study was done using the secondary data found in the patient's medical record. The study showed some patients with periapical cysts were at the Oral and Maxillofacial Surgery Department in the 2018-2019 period. The frequency and distribution of periapical cyst are primarily found in the third decade of life (39.1%). It found more in female patients (69.6%), more often involved maxillary lateral incisive (33.3%), mostly found at the apical of involved teeth (77.8%), involved teeth condition were more often pulp necrosis (63.0%), and endodontic treatment was the more chosen treatment (22.2%).

Preserving the vitality of teeth adjacent to a large radicular cyst in periapical microsurgery: a case report with 4-year follow-up

Background Radicular cysts may enlarge considerably, cause extensive bone destruction, and jeopardize the integrity of the associated vital teeth. The different treatment approaches are aimed mainly at eliminating the cystic epithelial membrane while reducing the risk of injury to vital structures. Contrary to other treatment modalities, preapical surgery offers an unequivocal single occasion resolution for the patient. However, it has been associated with higher risk of collateral damages. Case presentation A patient presented with a large radicular cyst originating from a maxillary lateral incisor. The adjacent central and canine teeth initially failed to exhibit responses to sensibility tests but showed signs of vitality. Microsurgical management was aimed at enucleating the cystic membrane while maintaining adjacent teeth vitality. Upon careful and controlled cyst enucleation under the dental operating microscope, the neurovascular bundle of one of the involved teeth was visualized and its integrity was maintained throughout the procedure. Results The procedure was successful and follow up recalls revealed recovery of normal sensibility of tooth 11 and 13 with complete bone regeneration around their apices. Conclusion Within the limitation of the present case report, we demonstrated that complete excision of large periapical cyst can be performed without sacrificing the vitality of the adjacent teeth, by preserving the integrity of their neurovascular supply through controlled microsurgical enucleation, and by a potential apical vascular repair ensuing unintended injury. Diagnosing the pulp vitality of non-offending teeth whose apices protrude into the cystic lumen is a complex process and can be misleading. Pressure from the growing cyst can inhibit vital teeth responses to neural-based sensibility tests leading to false negative results. Thus, in such cases, the use of blood perfusion-based vitality testing is recommended for correct initial diagnosis.

Management of large mandibular periapical cyst by cortical bone preservation: a case report

<p> </p><span lang="EN-IN">Management of large periapical cysts often require removal of overlying lateral cortical bone to gain access. We report a case in which huge periapical cyst was treated using a novel technique to preserve the overlying lateral cortical bone to facilitate faster healing of the defect. </span>

Uncommon involvement of multiple lesions in the oral cavity: A case report

In maxillomandibular complex lesions of various etiolopathogenesis may occur. Commonly, lesions are solitary, however, in in rare cases, multiple lesions with distinct natures affect the maxillo-mandibular complex. Until now, the recent literature, there are no reports of simultaneous impairment of periapical cysts, dentigerous and cementoblastoma in the same patient. We report the case of a 38-year-old with syndromic appearance, short stature, brachyfacial, showing hypertelorism, but no definitive diagnosis with multiple oral lesions in the jaws. In the reported case, a residual periapical cyst associated with the swelling in the anterior region of the maxilla occurring simultaneously to a dentigerous cyst and associated with tooth 35 cementoblastoma included. Despite the simultaneous involvement of multiple lesions with different etiopathogenesis is uncommon in the literature, this report seeks to emphasize the importance of thorough and systematic clinical examination, promoting proper conduct of maxillary lesions and perform the correct treatment.

A Rare Case of a Radicular Dens Invaginatus Associated with an Inflammatory Periapical Cyst

Radicular Dens Invaginatus (RDI) represent a rare form of dens invaginatus which develops in the root of the tooth after the crown development is completed that can sometimes cause complex pathological conditions that are difficult to diagnose. This case report describes a case of a RDI associated with an inflammatory periapical cyst. A 17-year-old female complained of mobility in tooth 22. The tooth showed gyroversion and colour change and no evidence of caries or root fracture. Axial slices and tridimensional reconstruction of the cone-beam computed tomography revealed the presence of a RDI on the distal surface of the root that extended from cervical to the apical third. The diagnostic hypothesis was symptomatic infectious apical periodontitis, and conventional root canal treatment was performed. Subsequently, it was opted for a complementary surgical approach, which involved an aspiration puncture bulletin with a collection of yellow-citrus liquid, periapical curettage, apicectomy, retro-preparation and retrofilling with Mineral Trioxide Aggregate (MTA). Histopathological examination revealed was inflammatory periapical cyst. After 3-years, repair of the area was evident. Surgical management of this rare condition can be favourable for resolving endodontic infection related to this dental anomoly.
