Subpontic osseous hyperplasia: Three case reports and literature review

Subpontic osseous hyperplasia (SOH) is an ectopic growth of bone occurring on the edentulous ridge beneath a fixed partial denture. The aim of this article is to present three patients with SOH with long-term follow-up and to make a current overview of the literature. Presented maxillary SOH is the second case in the dental literature. Intraorally the lesions were bone-hard and painless swellings in the subpontic space. Radiographically, the maxillary case was a nodular bone growth having similar radiodensity and trabeculation to the adjacent bone with a thin radiopaque border. Mandibular cases were bony growths, which were more radiopaque than the adjacent alveolar ridge. Follow-up radiographs revealed regression in two of the cases. Clinicians should take care not to cause the possible etiologies of SOH such as functional stresses and chronic irritation by the prosthetic treatments and be aware of SOH does not usually require treatment or a biopsy.

Endodontically related lesions on panoramic radiographs in a Turkish subpopulation

Objective: The purpose of this study was to evaluate the prevalence of detectable endodontically related lesions as determined from the reports of panoramic radiographs in a Turkish subpopulation. Materials and Methods: There were 19,625 reports of panoramic radiographs that were evaluated. Four investigators assessed the radiographs and reports that had been written. For each tooth of the subjects, the following items were surveyed: presence of periapical lesion, inadequate root canal treatment, external and internal root resorption. Results: The patients who had panoramic radiography reports were between the ages of 3 and 91 years (mean age 29,43 ± 18,83 years). 10,941 (56%) were female and 8684 (44%) were male patients. Inadequate root canal treatment was recorded in 588 (3%) radiography reports and it was more frequent in mandibular molar teeth. 2287 (11.7%) of the patients had periapical lesions and it was more frequent in maxillary incisor teeth and mandibular molar teeth. External resorption was observed in 61 (0.3%) patient records, while internal root resorption was reported in 14 (0.1%) reports. 81 inadequate root-filled teeth presented a periapical lesion. A positive strong linear correlation was found between the presence of inadequate root canal treatment and a periapical lesion among the patients (r = 0.098, P = 0.000). Conclusions: The results of this study suggest that external and internal root resorption were not frequent clinical conditions. The high frequency of periapical lesions and inadequate canal treatment in molar teeth indicate the need to improve the technical quality of root fillings, especially in molar teeth.

Stafne bone cavity incidentally ''Twice'' diagnosed on panoramic radiographs

A 63-year-old male patient admitted to another hospital for prosthetic restoration. On the panoramic radiograph a lesion was detected on the right mandible and he was referred for a cone beam computed tomography (CBCT) examination. The patient then admitted to our clinic for the diagnosis of this lesion. Review of the dental records revealed that a panoramic radiograph and a maxillofacial computed tomography scan were made about 10 years ago, and a Stafne bone cavity (SBC) was diagnosed. Moreover, a follow-up panoramic radiograph was made about 5 years ago. Despite the explanation given, the patient requested the CBCT examination in a private imaging center. The imaging features of the lesion were the same. In order to protect the patients from unnecessary radiation, the clinicians should make every effort to prevent duplicate imaging, and X-ray based advanced imaging techniques should be reserved for selected cases.

Prevalence of Distal Caries in Mandibular Second Molars Adjacent to Impacted Third Molars: A Retrospective Study Using Panoramic Radiography

Teeth may become impacted when they fail to erupt or develop into the proper functional location. Impacted teeth may therefore be non-functional, abnormal or pathologic [1,2]. Mandibular third molars (M3Ms) exhibit high impaction rates, ranging from 9.5 to 50% [3,4]. The etiology of M3M impaction depends on several factors, such as genetics, lack of space, retarded growth process, growth direction, eruption direction, and influence of external oblique line [5]. Impacted M3Ms may cause pain, periodontal disease, pericoronitis, caries, tumor, angle fracture, dental crowding, and cyst formation [6-11]. The complications related to M3Ms have been long studied and reported in literature. However, many of the researches conducted are on the pathoses related to the tooth itself, and not to its surrounding anatomic structures. More recently, distal caries in the mandibular second molars (M2Ms) have attracted researchers and clinicians attention, but there are still not many studies on this topic. Among all complications related to impact M3Ms, distal caries of the M2M is one of the most common (0.5-20%) [12-15]. A previous study reported that the prevalence of distal caries in M2Ms caused by third molars is up to 32% [16]. The aim of this study was to evaluate the correlation between the age and gender of the patient, side, eruption angulation and level of impaction of mandibular third molars and the prevalence of distal caries lesions in mandibular second molars.

Pericoronal radiolucency associated with an impacted premolar tooth

The mandibular second premolar is highly variable developmentally. Agenesis, abnormal tooth germ position, distal inclination of the developing tooth, and impaction are among the reported developmental anomalies. Detection of pathologic lesions associated with an impacted tooth usually requires removal of the tooth and the lesion. The purpose of the present report was to describe the radiographic and histopathologic features of a case of pericoronal radiolucency associated with an impacted mandibular premolar tooth.

Multiple calcifying hyperplastic dental follicles: A case report

This report describes a 31-year-old female patient with six impacted teeth. The crowns of the impacted teeth were surrounded with cyst-like lesions with a mixed internal structure and well-defined cortical borders. Microscopic examination of the specimen obtained from the follicle of the left mandibular third molar tooth revealed loose to moderately dense collagenous connective tissue with abundant calcified material and sparse epithelial islands. A diagnosis of multiple calcifying hyperplastic dental follicles was made.

Anahtar kelimeler: Osteoporoz, Panoramik Radyografi, Mandibular Korteks Abstract Is it diagnosis or chance? Diagnosis of osteoporosis on panoramic radiographs of two young women (case report) Osteoporosis is a metabolic bone disease that has a high morbidity-mortality rate and requires expensive treatment. The clinical diagnosis of this disease is fractures with minor trauma in bones due to a reduction in bone mineral density. Early indicators of osteoporosis (thinning in inferior and angular mandibular cortex, changes in the trabecular architecture) were determined on panoramic radiographs of 26 and 27 years old female patients. Analyses of bone mineral density and bone mineral content were performed. The results were in concordance with osteoporosis. It is concluded that panoramic radiographs may be useful in early diagnosis of osteoporosis even in younger patients. Besides, these two cases revealed that dentists can play an important role in early diagnosis, prevention and treatment of osteoporosis in patients.
