The head and neck is the second most common region for extranodal lymphomas. The most common site is the Waldeyer's ring, and involvement of the base of tongue is extremely rare. We present a rare case of a young female with primary non-Hodgkin's lymphoma (NHL) of the base of tongue. A 23-year-old female presented with a history of foreign body sensation in her throat for a month. Oral examination revealed a lobulated smooth mass at the base of tongue. Contrast-enhanced computed tomography neck shows polypoidal homogeneously enhancing soft tissue lesion in the base of tongue extending till the lateral pharyngeal wall. The biopsy of the lesion was reported as NHL. Hodgkin's lymphoma should be kept in the differential diagnosis of swelling arising from the base of tongue. We report a rare and varied presentation of extranodal lymphoma. A careful clinical evaluation supported by histopathological and radiologic investigations will help in identifying the disease at an early stage, resulting in a better prognosis.

Introduction: The third molar develops entirely after birth and also it is the last tooth to erupt in all ethnic groups despite racial variations in the eruption sequence. Tooth development with effects on tooth size, shape, position, and total absence is affected due to environmental factors, systemic diseases, genetic polymorphisms, and teratogens. Aims and Objectives: The aim of this study was to assess the prevalence of agenesis, impaction, and pararadicular radiolucencies in relation with third molars. Materials and Methods: One hundred digital orthopantomograph (OPG) scans of patients of age ranging from 18 to 25 years were selected randomly from the digital OPG database of the Department of Oral Medicine and Radiology, and then assessment and analysis were carried out. Results: Overall agenesis rate was about 14.5%. Bilateral agenesis of maxillary and mandibular third molars was about 14% and 13%, respectively. Overall impaction rate was about 21.92%. Mesioangular impaction rate was about 57.33% whereas distoangular impaction rate was about 26.66%. Prevalence of pararadicular radiolucencies was only about 0.8% with mandibular predilection. Conclusion: As the agenesis of the third molars is increasing, they can be considered as vestigial. Prevalence of impaction of the third molars is increasing. Pararadicular radiolucencies are mostly seen with mandibular third molar.

Botulinum toxin type A (BTX-A) (Botox, Allergan, Irvine, CA, USA) has been studied since the late 1970s for the treatment of several conditions associated with excessive muscle contraction. Smile esthetics has become a major concern among patients and orthodontists. This article describes the efficient, nonsurgical, and less invasive use of BTX-A injection for the correction of a gummy smile in orthodontics.

Periodontal plastic surgical procedures aimed at the coverage of exposed root surface have evolved into routine treatment modalities. Coronally advanced flap (CAF) was the most frequently used mucogingival procedure to achieve root coverage. Gingival recession resulting in root exposure is a common problem faced by clinicians. The continuous endeavor for innovation of newer interdisciplinary treatment modalities has resulted in the use of a passive object such as the orthodontic button being used to provide the initial stabilization in cases of root coverage using a CAF. The objective of this case report is to evaluate the effectiveness of a new treatment approach which consists of CAF procedure combined with orthodontic button application for the stabilization of flap for the treatment of Miller′s Class I recession defects. After the application of orthodontic buttons in the middle third of the tooth surface, a split-full-split flap was raised for tooth number 43, and the flap was sutured 3-4 mm coronal to cementoenamel junction, and the central part of flap was suspended with sutures to the orthodontic button to maximize the stabilization of the immediate postoperative flap location. Clinical parameters such as probing depth and clinical attachment level were recorded at 1 month postoperatively. Complete root coverage was achieved when evaluated from baseline to 3 months along with gain in clinical attachment level and keratinized tissue. The final esthetics, both color match and tissue contours, were highly acceptable. One-month postoperative results showed that the CAF combined with the orthodontic button for stabilization is a very effective approach even in the treatment of Miller′s Class I recession defects.

It is a fact that mind and body share an intimate relationship. There are many ways in which mental and physical health impact each other. Psychosocial factors play a part in the pathogenesis of physical health, and oral health is no exception. Chronic and painful oral symptoms lead to psychosocial disorder and at the same time, some patients with psychosocial disorders experience painful oral and facial symptoms. Several investigators have concluded that psychosocial factors play an important role in the pathogenesis of an array of oral problems, ranging from poor oral hygiene to chronic pain disorders, such as temporomandibular joint disorders, burning mouth syndrome, and atypical pain. This review aims at the in-depth analysis of the correlation between psychosocial disorders and various oral symptoms.

Science is presently undergoing a great evolution, taking humanity to a new era: The era of nanotechnology. Nanotechnology is the field of science and technology pertaining to the creation and use of materials or devices at nanometer scale. Nanoscale is small in size, but its potential is vast. Since 1990s, nanotechnology has been exploited for potential medical and dental applications. Nanotechnology has numerous applications in the field of nanomedicine, nanomaterials, nanorobotics, implantology, and biotechnology. Nanomaterials in dentistry can be metals, ceramics, polymers, implant modifications, and composite materials that demonstrate novel properties when compared with conventional materials due to their nanoscale features. The present article focuses on the various applications of nanotechnology in the field of dentistry, especially prosthodontics.

Odontomas are nonaggressive, hamartomatous developmental malformations of odontogenic origin. They are considered one of the most common odontogenic lesions composed by diverse dental tissues. They may interfere with the eruption of an associated tooth and are more prevalent in the posterior mandible. The eruption of a complex odontoma into the oral cavity is rare. Here, we report such two rare cases of gigantic erupted complex composite odontomas.

Treatment of benign and malignant tumors may involve surgical resection of the mandible, which may be segmental or hemisectioned. The prosthetic rehabilitation of resected mandible becomes difficult when preprosthetic planning is not considered. Preprosthetic plastic surgery and/or implant assisted overdenture may enhance the prosthetic rehabilitation of edentulous patients who have undergone resection of the mandible. Due to medical conditions, unwillingness for additional surgery or economical restraints, the treatment is limited to guidance flange prosthesis. The guidance flange prosthesis helps in directing the deviating mandible to improve form and function. This case report describes a procedure for fabricating customized guiding flange prosthesis to rehabilitate edentulous segmental mandibulectomy.

Objective: Purpose of the study was to determine the prevalence of dental fluorosis and its pattern in primary and permanent teeth among 6-12-year-old Pakistani school going children living in Dammam, Saudi Arabia. Materials and Methods: This cross-sectional study was performed between June and September 2014. A total number of screened children were 496 among them 259 were males and 237 were females. World Health Organization′s scale was used to examine children for dental fluorosis. Results: Prevalence of dental fluorosis was found to be 33% among a total number of examined children. Among the children who had dental fluorosis (n = 164), it was observed that mild and moderate level of fluorosis were prevailing in 113 (69%) children. Furthermore, a number of males who were suffering from fluorosis was more than the females. There were 97 males and 67 females found affected from dental fluorosis and this difference was found statistically significant (P = 0.038). Conclusion: Prevalence of dental fluorosis among Pakistani school going children was not high. However, the severity of fluorosis was alarming, mild, and a moderate level of fluorosis was observed in most of the children who were affected from fluorosis.
