Ultrasonography with color Doppler and power Doppler in the diagnosis of periapical lesions

Aim: To evaluate the efficacy of ultrasonography (USG) with color Doppler and power Doppler applications over conventional radiography in the diagnosis of periapical lesions. Materials and Methods: Thirty patients having inflammatory periapical lesions of the maxillary or mandibular anterior teeth and requiring endodontic surgery were selected for inclusion in this study. All patients consented to participate in the study. We used conventional periapical radiographs as well as USG with color Doppler and power Doppler for the diagnosis of these lesions. Their diagnostic performances were compared against histopathologic examination. All data were compared and statistically analyzed. Results: USG examination with color Doppler and power Doppler identified 29 (19 cysts and 10 granulomas) of 30 periapical lesions accurately, with a sensitivity of 100% for cysts and 90.91% for granulomas and a specificity of 90.91% for cysts and 100% for granulomas. In comparison, conventional intraoral radiography identified only 21 lesions (sensitivity of 78.9% for cysts and 45.4% for granulomas and specificity of 45.4% for cysts and 78.9% for granulomas). There was definite correlation between the echotexture of the lesions and the histopathological features except in one case. Conclusions: USG imaging with color Doppler and power Doppler is superior to conventional intraoral radiographic methods for diagnosing the nature of periapical lesions in the anterior jaws. This study reveals the potential of USG examination in the study of other jaw lesions.

Assessment of anxiety and depression in patients with burning mouth syndrome: A clinical trial

Introduction: Burning mouth syndrome is a chronic pain syndrome primarily affecting elderly women with hormonal changes or psychological disorders. It is multifactorial in origin, often idiopathic and its etiopathogenesis, majorly being neuropathic, largely remains enigmatic. Aim: To determine the prevalence of burning mouth symptom, in elderly women and evaluate local and systemic causes responsible for burning sensation. Materials and Methods: 100 elderly postmenopausal women were included in the study out of which 56 had a chief complaint of burning sensation. These patients were evaluated for the levels of anxiety and depression by means of questionnaire. The severity of burning and the response to the treatment was assessed with a five point Visual Analog Scale. The results were analyzed using “Chi-square test”. Results: There was statistically significant increase in the levels of anxiety and depression in the study group. Conclusion: The present study clearly indicates that most of the patients had moderate to severe levels of depression, which suggests that anxiety and depression are constant features in postmenopausal female patients.

Blue rubber bleb nevus syndrome: Prominent oral findings

Blue rubber bleb nevus syndrome is a rare disorder characterized by multiple cutaneous venous malformations in association with visceral lesions, most commonly affecting the gastrointestinal tract. Oral cavity lesions occur in 59 to 64% of cases. We report a unique presentation of this syndrome in a 25-year-old male patient with prominent oral findings. This is a sporadic case, started during early childhood, progressively increasing in number and size. Oral vascular lesions were part of gastrointestinal involvement. Associated cardiac abnormalities were also observed. An early diagnosis of this syndrome is required as it gets complicated with bleeding, anemia and other systemic complications.

Cowden syndrome- Clinico-radiological illustration of a rare case

Cowden syndrome (CS) or multiple hamartoma syndrome is an infrequent genodermatoses, which is inherited as an autosomal dominant trait resulting from the mutation in the Phosphatase and Tensin homolog gene on the arm 10q and is principally characterized by multiple hamartomas with an increased risk of development of malignancies. Facial and oral signs are remarkable in the form of multiple papules and trichilemmomas on the face. We report one such rare case of CS in a 19-year-old patient who was diagnosed on the basis of her oral mucosal lesions and was further investigated and diagnosed with other hamartomas. The present case report signifies the responsibility of the oral physician in the early diagnosis of this progressive pathological syndrome as it leaves its footmark in the oral cavity in the form of oral mucosal lesions.

Limbal dermoid in Nager acrofacial dysostosis: a rare case report

Nager syndrome, also called preaxial acrofacial dysostosis, comprises two groups of defects involving the limbs and craniofacial region, respectively. This syndrome is rare and only 70 cases have been reported in the literature. The exact cause of this syndrome is unknown, but there is indication that it is genetically based. Ocular manifestations of this syndrome include widely separated downward slanting eyes, absence of eyelashes, ptosis of upper eyelids and colobomas on the inner aspect of lower eyelids. We report limbal dermoid in a patient with Nager syndrome. We did not find such an association of “Limbal dermoid in Nager acrofacial dysostosis syndrome” on PubMed using Nager acrofacial dysostosis, limbal dermoid and ocular manifestations as the keywords.

Dentinogenic Ghost Cell Tumor — A Neoplastic Variety of Calcifying Odontogenic Cyst: Case Presentation and Review

Context: The calcifying odontogenic cyst (COC), also referred to as calcifying ghost cell odontogenic cyst (CGCOC) is a heterogeneous lesion existing either as cystic or solid variant. Due to the fact that all CGCOC lesions are not cystic, and the biological behavior is often not consistent with a cyst, there has always been a controversy as to whether COC is a cyst or a tumor. The dentinogenic ghost-cell tumor (DGCT), a solid variant of the COC, is an uncommon odontogenic neoplasm occurring predominantly in later life. Case report is followed by a concise review and disambiguation of controversial terminologies regarding nomenclature of COC. Case Report: We report a case of 33-year-old female patient who presented with an insidious, steadily increasing swelling on the left side of her face since 8 months. Patient reported slight difficulty in eating because of reduced intraoral space and an obvious concern with facial disfigurement. There was no contributory dental or medical history. Intraorally, a hard, well defined, bicortical swelling was noted in left maxillary region with slight mobility of the associated teeth and normal appearing overlying mucosa. A provisional diagnosis of adenomatoid odontogenic tumor was made, and orthopantomogram, paranasal sinus radiograph and computed tomograpy scan of the face were acquired. A radiographic diagnosis of COC was made, which was subsequently confirmed on histopathology postenucleation of the tumor mass. COC has been seen to be of extensive diversity in its clinical and histopathological features as well as in its biological behavior. Conclusion: The present case of 33-year-old female was diagnosed as DGCT, a tumorous form of COC, due to its characteristic histological features; numerous ghost cells and dentinoid material.

Parosteal osteosarcoma of mandible: A rare case report

With the exception of multiple myelomas, osteosarcoma is the most frequently occurring primary malignant bone tumor with an overall incidence of 1:100,000/year. It has greatest predilection for the metaphyses, most frequently femur and tibia. However, osteosarcomas affecting the craniofacial bones are infrequent. Two main types: intramedullary and juxtacortical varieties are seen. Juxtacortical variety is further subdivided into periosteal and parosteal variants. Due to its rarity, only 13 cases of parosteal osteosarcoma have been reported till date. A 35-year-old male patient with affected postirradiated mandible is being reported as the 14th case of this kind with its unique benign presentation and less aggressive nature.

Roles of serum uric acid, prolactin levels, and psychosocial factors in oral lichen planus

Free radicals play important roles in the mechanisms underlying lichen planus (LP). Uric acid (UA) is an important anti-oxidant in plasma. Prolactin (PRL) is an immunomodulatory hormone that may promote LP, as has been documented in other autoimmune disorders, such as systemic lupus erythematosus, rheumatoid arthritis, and psoriasis. PRL has multiple immune-stimulatory effects and promotes the development of such autoimmune disorders. Prolactin and uric acid may serve as biomarkers of disease activity in lichen planus. The aim of the present study was to evaluate the roles of depression, stress, and anxiety in LP, as well as serum levels of UA and PRL as potential biomarkers of disease activity and compare these findings with those of the control group. Thirty-nine patients clinically diagnosed with oral LP (study group) and 39 age- and sex-matched controls (control group) were selected in this study. Serum UA and PRL levels were measured. The Depression Anxiety Stress Scale-21 was used for psychometric evaluation of LP patients and controls. Serum UA level was found to be significantly higher in the control group as well as during the remission phase of disease in the study. There was no significant difference in serum PRL levels between cases and controls. Depression and stress scores were higher in the study group.

Incidence of oral lichen planus in perimenopausal women: A cross-sectional study in Western Uttar Pradesh Population

Background: Hormonal fluctuations during menopause lead to endocrine changes in women, especially in their sex steroid hormone production. Studies have documented the role of estrogen and progesterone (Pg) on autoimmune disorders such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Lichen planus (LP), an autoimmune disorder, seen frequently in perimenopausal women, may also get affected by sex steroid hormones, but no direct relationship has been established yet. Aim: The aim of this study is to find the incidence of oral LP (OLP) in perimenopausal women and evaluate the factors associated with it. Materials and Methods: This cross-sectional study was conducted over a period of 1 year. All the perimenopausal women (44.69 ± 3.79 years) who came to the dental outpatient department were evaluated for the presence of LP and various factors associated with it. Depression Anxiety Stress Scale-21 questionnaire was used for psychometric evaluation of perimenopausal women. Results: According to our study, incidence of LP in postmenopausal women was 10.91%, which is higher than incidence of LP in general population, i.e., 0.5% to 2.0%. Incidence of LP increased with the severity of depression in perimenopausal women (P = 0.000). Conclusion: The incidence of OLP is higher in perimenopausal women than in general population and increases significantly with increase in the severity of depression. LP in perimenopausal women can be mediated by declined level of estrogen and Pg directly or indirectly through causing depression that can trigger LP.

Age estimation in children by measurement of open apices in teeth: a study in North Indian population

Age estimation is a prerequisite in forensic medicine, paediatric endocrinology and orthodontic treatment. Dental development has been proven to be suitable for age determination in children because of its lower variability. The aim of this study was to evaluate the applicability of using the open apex method proposed by Cameriere et al. for age estimation in Indian children. Digitalized panoramic radiographs were retrieved from the Department of Oral Medicine & Radiology of 558 Indian children (261 girls, 297 boys) with an age range from 5 to 15 years. The seven left permanent mandibular teeth were evaluated for length and open apices. Dental maturity was evaluated using measurements of the seven left permanent mandibular teeth (xi = Ai/Li, i = 1,...,7), the sum of the normalized open apices (s) and the number (N0) of teeth with root development complete. Using a stepwise multiple regression model, a relationship between open apices, N0 and age was evaluated. Statistical analysis revealed high accuracy with the morphological variables explaining 88.5% of the variations in estimated chronological age. This research suggests an open apex method could be successful for age estimation in Indian children and could be applied in legal issues pertaining to forensic medicine.
