Comparison of the Effect of Different Bonding Agents on the Microleakage of Two Hydrophilic Pit and Fissure Sealants: An Study.

Aim: To compare the impact of fifth- and seventh-generation bonding agents on the microleakage between Embrace WetBond sealants and Ionoseal.

Materials And Methods: Forty extracted human premolar teeth were used for the study and grouped according to different sealants and bonding agents-group I: Embrace WetBond sealant with fifth-generation bonding agent; group II: Embrace WetBond sealant with seventh-generation bonding agent; group III: Ionoseal with fifth-generation bonding agent; group IV: Ionoseal with seventh-generation bonding agent. For microleakage evaluation, all the teeth were subjected to invasive sealant placement using the respective sealant materials in combination with bonding agents as specified.

Clinical Outline of Oral Diseases.

Oral diseases are pathologic conditions that affect oral and maxillofacial tissues. Dental caries and periodontal diseases are the most common forms of oral diseases, but there are a wide variety of diseases that can occur in oral and maxillofacial tissues. These oral diseases range from metabolic, inflammatory, infectious, neoplastic, autoimmune, developmental, to idiopathic origin.

Tooth agenesis: A susceptible indicator for colorectal cancer?

Context/background: Tooth agenesis (excluding third molars) is a common congenital disorder that affects 2.2-10% of the general population. A number of different genes have been shown to be associated with cases of tooth agenesis including AXIN2, IRF6, FGFR1, MSX1, PAX9, and TGFA.

Evaluation of changes in salivary composition in renal failure patients before and after hemodialysis.

Background: Saliva plays a major role in preserving the integrity of oral tissues. The oral health of renal failure patients could be negatively affected by the underlying pathology, the dialysis treatment, or an altered salivary composition. Major systemic changes occur during hemodialysis (HD), which could affect the flow rate and biochemical composition of saliva.

Correlation of lip patterns, gender, and blood group in North Kerala population: A study of over 800 individuals.

Context: With the ever-changing field of criminal justice, the constant revision of criteria for acceptable evidence by the judiciary poses new challenges in forensic investigation. The applicability of cheiloscopy in individual identification is an area of extensive research in recent years.

Objectives: The aim of the present study was to determine the distribution of different lip print patterns in North Kerala population, to assess any sexual dimorphism in lip patterns, and to correlate lip print patterns with ABO and Rh blood groups.

Gender determination by odontometric method.

Context: Gender determination is central in establishing personal identification from human skeletal remains. The study was conducted to find out the accuracy with which gender can be determined by odontometric methods.

Aims: To investigate the mesiodistal (MD) and buccolingual (BL) dimensions of all the teeth of permanent dentition to find new parameters to differentiate between male and female teeth and to assess whether each type of linear measurement can be used independently in odontometric sex differentiation.

Dermoid Cyst of Submental Region Mimicking Pilomatricoma.

Diagnosis of midline neck swellings may give a myriad of options, ranging from ranula, thyroglossal duct cyst, cystic hygroma, cystic lymphangioma, epidermoid, dermoid and teratoid cysts to benign or malignant neoplasms of the mucosa or salivary glands and also rare skin appendage tumours like pilomatricoma or pilomatrix carcinoma. Various pitfalls are encountered in diagnosing these midline swellings as most of the features are overlapping. Careful history and examination have to be complemented with other diagnostic aids such as conventional radiography, ultrasonography, aspiration cytology and computed tomography to arrive at a correct diagnosis.

Prosthodontic Management of Xerostomic Patient: A Technical Modification.

Xerostomia is often a contributing factor in both minor and serious health problems. It can affect nutrition and dental as well as psychological health. Common problems faced by such patients are glossitis, mucositis, angular cheilitis, dysgeusia, and difficulty in chewing and swallowing.

Proposed Clinico-Pathological Classification for Oral Exophytic Lesions.

Oral exophytic lesions often have proven to be diagnostically challenging due to the varied clinical presentation. The exophytic growth of the oral lesions is due to the type of pathology and histological changes. Careful clinical interpretation with a better histological understanding of exophytic lesions may ease the diagnosis from the differential diagnosis panel.

Eosinophilic ulcer of the tongue: a rare and confusing clinical entity.

Eosinophilic ulcers are rare, benign, reactive and often self-limiting lesions of the oral cavity. Although the aetiology is not clear, trauma is believed to play a role in their development. Clinically, the lesion manifests as an isolated ulcer, with raised, indurated borders and a yellow fibrinous floor; because of its long duration it often leads to the suspicion of squamous cell carcinoma.

Pericoronal occurrence of cemento-ossifying fibroma: an unexemplified and unusual case report with review of literature.

The Cemento-ossifying fibroma (COF) is an odontogenic neoplasm that is predominantly considered as a fibro osseous lesion of the jaw bone. The histogenetic origin of COF was thought to be derived from the periodontal cells, which have the ability to form fibrous, cementum and osseous tissue. Due to the periodontal cellular origin, the lesion often occurs in the radicular portion of the bicuspid and molar tooth region of the lower jaw.

Radiographic assessment of influence of cleft width and canine position on alveolar bone graft success: a retro-prospective study.

Purpose: To evaluate the effect of cleft width and the pre-surgical position of the permanent cuspid, on the success of secondary alveolar bone grafts, using preoperative and post-operative radiographs.

Methodology: A total of 20 cases treated with secondary alveolar bone grafting for alveolar clefts were included in the study. Pre-surgical maxillary occlusal radiograph was used to determine the cleft width.

Kinetics of drug release from a biodegradable local drug delivery system and its effect on Porphyromonas gingivalis isolates: An in vitro study.

Background: Conventional anti-microbial therapy largely consisted of systemic administration of various drugs effective against periodontal pathogens, but fraught with several problems. Based on the concept of local drug delivery a bioresorbable device made of pure fibrillar collagen has been developed. The aim of this study was to study the release of Tetracycline from this collagen fiber (Type I collagen) impregnated with Tetracycline and its antibacterial activity against Porphyromonas gingivalis.

Immediate placement of dental implants in the mandible.

This case describes extraction of teeth in the mandibular arch, i.e., 41 42 43 44 45 51 52 53 54 55 56 57 58 (grade two mobility), followed by immediate placement of four dental implants (3i biomet), two in the 45 55 region and two dental implants in 12 21 region.

Metastatic follicular thyroid carcinoma to the body of the mandible mimicking an odontogenic tumor.

Metastatic tumors to the jawbones are uncommon. Metastatic lesions to the oro-facial region may be the first evidence of dissemination of an unknown tumor from its primary site. Follicular thyroid carcinoma rarely presents initially as a distant metastatic lesion within the mandible.
