Background: Analysis of palatal rugae patterns, which are similar to fingerprints, is one of the techniques used in forensic sciences for human identification. As palatal rugae patterns are genetically determined, they can also be used in population differentiation and gender determination. Hence, we aimed to record the distribution of the predominant rugae pattern in Kerala population. Materials and Methods: A total of 100 maxillary study models (40 males and 60 females) recorded from Kerala population within the age group of 17-25 years were analyzed. The dental casts were examined for the interpretation of the total number, length, shape, location and unification of rugae. Chi-square test and unpaired t-test were employed for statistical analysis. Result: The total number of rugae was significantly (P < 0.001) greater in females than males. Regarding the shape, wavy pattern predominated in both males and females, followed by curve, straight, divergent, convergent and circular pattern. Circular pattern was more in males than females. The rugae patterns were located more in between mesial aspect of first premolar to mesial aspect of second premolar. Conclusion: The palatal rugae and their features of an individual may be considered as a reliable guide for identification purpose, provided antemortem casts are available. Nevertheless, gender differentiation is evident in terms of number and shape of rugae.

Halitosis is a condition where the breath is altered in an unpleasant manner for the affected individuals and impairs them socially as well as psychologically. Halitosis can be clinically classified as real halitosis, pseudohalitosis, and halitophobia. Real halitosis has oral and extra-oral etiologies and the pathophysiology involves interaction of anaerobic microbes (mainly) with the proteins present in the oral cavity fluids and contents, resulting in production of volatile sulfur compounds (VSCs). These VSCs, beyond responsible for halitosis, can also initiate and accelerate periodontal disease progression. Thus, this review is about the pathophysiology and various etiologies of halitosis, the knowledge of which can help in the betterment of treatment options.

The aim was to determine the frequency and distribution of oral squamous cell carcinoma (OSCC) involving tongue among patients by studying biopsy specimens obtained from the archives of the Department of Oral and Maxillofacial Pathology, College of Dental Sciences, Davangere, Karnataka, India, during the past 13 years.Data for the study were retrieved from the case records of patients. Analyzed clinical variables included age, sex, anatomical site, and histological diagnosis.Of the 369 squamous cell carcinoma involving head and neck region, we found 52 biopsies reported exclusively involving tongue. Lateral border of the tongue was most commonly involved (43 cases, 82.7%), followed by base of tongue and posterior part of tongue. The patient were affected over a wide range of 27-80 years with mean age of 55.75 years and peak incidence was seen in the fourth and fifth decades of life, with the male: female ratio of 1.7:1.The prevalence rate of OSCC involving tongue showed a definite geographic variation when compared with a study done in other parts of the world.

Oral lichen planus (OLP) is a relatively common, chronic inflammatory condition that frequently presents with symptoms of pain and burning sensation. It is generally a very unrelenting disorder despite several kinds of treatment. Only symptomatic OLP requires treatment, and it remains a challenging predicament. Efforts are made in a sustained manner for searching for novel therapies for symptomatic OLP. Therefore, this study was aimed to compare the efficacy of treatment with topical pimecrolimus cream 1% with that of triamcinolone acetonide oral paste 0.1% in subjects with symptomatic OLP.A prospective, parallel-group, randomized, active control clinical study was conducted among 30 symptomatic OLP subjects (20 females and 10 males, with 15 patients in each treatment group) treated with topical pimecrolimus 1% cream and triamcinolone acetonide 0.1% oral paste four times daily for two consecutive months and treatment-free follow-up was performed for 2 months. Pain or burning sensation, mean clinical score and presence of erythematous areas were assessed. The data obtained were statistically analyzed using Wilcoxons Rank test and the Mann Whitney test.Subjects in both the groups showed significant improvement in symptom scores; however, the overall treatment response was higher in the pimecrolimus group compared with the triamcinolone acetonide group. On intergroup comparison, there was no statistically significant difference between the groups in the reduction in burning sensation (P = 0.18) and erythematous area (P = 0.07), but there was a statistically highly significant improvement in reduction of clinical scoring (P < 0.01%). Following the termination of the treatment, sustained remission of symptoms and long-lasting therapeutic effects was detected in 93.3% of the patients treated with pimecrolimus.Topical pimecrolimus 1% cream showed better therapeutic response compared with triamcinolone acetonide 0.1% oral paste in subjects with symptomatic OLP.

Bone removal is necessary for extracting the third molars that are erupted, partially erupted, and/or impacted in bone. Hence, it is necessary to choose a surgical method or instruments that conform to anatomic landmarks and are based on physiological principles. Many authors have reported injuries to the adjacent tooth, especially the distal part of periodontium after removal of second molar. Hence, the present study was undertaken to assess and compare the surgical and postsurgi-cal outcomes of third molar removal using piezoelectric surgery and rotary bur.A total of 30 healthy adult individuals who were in need of prophylactic removal of impacted man-dibular third molar tooth with ideal condition were included for the study. Individuals were divided randomly into study groups of 15 each, so that the difficulty of surgery will be the same in both the groups. Group I - piezoelectric osteotomy technique and group II - rotary osteotomy technique. The rotary device consists of a hand piece and a rotary speed ranging around 35,000 rpm was used. The piezoelectric device consists of a hand piece, and a frequency of 25 to 29 kHz with a microvibration of 60 to 200 mm/sec was used with a boosted working mode. Data were analyzed using unpaired t-test and qualitative data were analyzed using Fischers exact test.The average age of the study subjects in the piezo-surgery group and rotary group was 28.40 2.69 and 30.06 3.15 years respectively. The time taken for removal of impacted tooth by rotary bur was less than that by piezoelectric device, which was significant statistically (p < 0.05). Until the 4th postoperative day, severity of pain experienced was more in the rotary group, which was statistically significant (p < 0.005). Mouth opening was significantly better in the piezoelectric group as compared with rotary bur until the 7th postoperative day.The piezosurgery method reduces postoperative pain, trismus, and swelling. Also, it may play an important role in increasing bone density within the extraction socket and decreasing the amount of bone loss of adjacent tooth in the distal aspect.In clinical practice, piezosurgery plays an important role because piezosurgery reduces postoperative pain, trismus, and also swelling.

Predentin, the unmineralized organic matrix is important in maintaining the integrity of dentin. It is usually thick where active dentinogenesis occurs. A wide variation in its thickness is reported. Hence, we determined the variation in predentin thickness at various sites of different age groups.60 freshly extracted teeth (maxillary and mandibular first premolars) were divided into three groups with 20 teeth in each as, Group 1 - teeth with incomplete root formation (age <16 years), Group 2 - teeth with complete root formation (aged between 16 and 30 years), Group 3 - teeth of patients aged above 30 years. The teeth were fixed, decalcified and sections of 6 thickness were obtained, and stained with hematoxylin and eosin. The distance between the odontoblastic cell layers of the pulp to the border line of the dentin was considered for the measurement of the predentin thickness. A total of nine sites were considered for each specimen.The present study revealed varied mean predentin thickness at all nine sites in all three age groups. Maximum and minimum thickness was observed at the apex and pulp floor respectively in all three groups. There was a statistical significant difference in predentin thickness between groups 1 and 3 and 2 and 3.The predentin thickness in the first group gradually increased toward the growing end near the apex, while it was relatively constant in the second group and increased overall thickness at all the sites in the third group. A notable finding was a linear increase with age in width of the predentin and the thickness vary as a function of odontoblastic activity during different stages of tooth development.

Mucormycosis is an opportunistic fungal infection, more commonly observed in immunocompromised patients. The mode of infection is via the inhalation route and infection begins initially in the nose and paranasal sinuses with subsequent invasion into the vascular tissue, eventually leading to thrombosis and necrosis of nearby hard and soft tissues. Here, we report a case of chronic osteomyelitis of the maxillary bone with fungal infection (mucormycosis) and extensive tissue necrosis in an uncontrolled diabetes mellitus patient.

Burkitt's lymphoma is an aggressive form of Non-Hodgkin's lymphoma composed of malignant cells of B lymphocyte origin. Burkitt's lymphoma is a rarity in the Indian subcontinent. Though intraoral Burkitt's lymphoma in HIV positive individuals is very uncommon, its importance lies in the fact that it is often the first sign of the underlying immunosuppression. We present a case of Burkitt's lymphoma in right maxillary region which was the first manifestation of HIV in the patient.

To record the prevalence rate of dental anomalies in Dravidian population and analyze the percentage of individual anomalies in the population.A cluster sample analysis was done, where 244 subjects studying in a dental institution were all included and analyzed for occurrence of dental anomalies by clinical examination, excluding third molars from analysis.31.55% of the study subjects had dental anomalies and shape anomalies were more prevalent (22.1%), followed by size (8.6%), number (3.2%) and position anomalies (0.4%). Retained deciduous was seen in 1.63%. Among the individual anomalies, Talons cusp (TC) was seen predominantly (14.34%), followed by microdontia (6.6%) and supernumerary cusps (5.73%).Prevalence rate of dental anomalies in the Dravidian population is 31.55% in the present study, exclusive of third molars. Shape anomalies are more common, and TC is the most commonly noted anomaly. Varying prevalence rate is reported in different geographical regions of the world.
