Implant-supported prosthesis has high predictability and success and improves quality of life. This study aims at assessing awareness among the patients regarding implant-supported prosthesis.A cross-sectional study was conducted among 391 study participants. A structured questionnaire was distributed to assess implant-related awareness among the study participants. The questionnaires were analyzed for the responses.Among the 391 respondents, 37.5% of the respondents reported having moderate knowledge regarding the tooth replacement options. Nearly 50% considered implants as a viable treatment option. The majority of them enlisted the dentist as the major source of information regarding implants, and media had a share of about 7.03% only. High cost was a major barrier in selecting implants as a treatment option.This survey showed that awareness among people was low regarding the dental implants. Efforts need to be directed to increase the awareness levels by utilizing media as a tool to achieve the target.A patient who is aware of the advantages of the implant-supported dentures will make an informed decision for better functional stability and retention of the denture, especially in the mandibular arch.

The main reason for seeking orthodontic treatment for Class II malocclusions is aesthetic improvement. Growth modification treatment procedures offer better results for a patient with significant potential growth.The aim of this cephalometric clinical study was to distinguish skeletal and dental corrections on skeletal class II division I growing subjects with Twin Block therapy (TB) and the changes were assessed using SO-analysis by Pancherz.Strict diagnostic protocol viz. growing individuals with horizontal growth pattern, skeletal class II due to retrognathic mandible with positive VTO, bilateral class II molar relation, minimal crowding in either arch or overjet more than 5mm was used. Out of 28 selected cases,17 patients received TB therapy and 11 patients were maintained as control group. Standard removable TB appliances with lower incisor capping were delivered to treatment group. The horizontal advancement was about 8mm and 2-3mm vertical opening between the upper and lower central incisors were maintained for all the cases. The mean time interval between the initial (T1)and post treatment (T2) cephalograms of Twin-Block group was 11 month,with a range of 8 month to 13 month. In the control group, the mean time interval between the first (C1)and second (C2) cephalometric films was 12 month,with a range of 10 month to 14 month.T1and T2 cephalograms were traced and S-O analysis was used to segregate dental and skeletal effects.SPSS software was used for statistical analysis.Skeletal Changes: In this study, the mean movement of maxilla was 0.67mm which represents significant restriction of forward maxillary growth in contrast to control groups. Dental Changes: In this study the maxillary molars appear to move distally with a mean value of 0.13mm. Comparing this to the movement of maxillary jaw base itself, maxillary distal movement of molar is less. But still it contributes to Class II correction.The overjet reduction and molar relation correction are more skeletal in nature.

Mucormycotic skull base osteomyelitis in immunocompetent individuals is extremely rare clinical entity, with only 8 cases reported in literature till date. It is the most acute, fulminant and deadly infection most commonly seen arising from sinonasal tract and middle ear infections. The involvement of the bone is lately seen due to angioinvasiness nature of this opportunistic fungi infection. When seen in immunosuppressed individuals it can be more aggressive and can spread extensively to the deep facial structures, orbits and intracranially with erosion of the skull base and cervical vertebrae.Early diagnosis and prompt treatment planning for this malignant behavior type of infection is to reduce the mortality rate. We report a rare case of 61-year-old male patient complaining of cranial neuropathy of maxillary branch of trigeminal nerve from 22 days. Magnetic resonance imaging revealed radiodense lining of the right sphenoidal sinus with a lesion in infratemporal region provisionally diagnosed as meningioma. We performed surgical excision of the lesion with zygomatic arch access osteotomy. Histopathological examination revealed mucormycotic skull base osteomyelitis. Patient was started on amphotericin B therapy immediately. © 2013 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

This paper attempts to summarise the findings accumulated within the last few years concerning the hormone of darkness melatonin. Based on its origin, from the pineal gland until recently it was portrayed exclusively as a hormone. Due to its lipophilic nature, it is accessible to every cell. Thus, in the classic sense it is a cell protector rather than a hormone. Recent studies, by Claustrat et al. (2005), detected few extrapineal sources of melatonin like retina, gastrointestinal tract, and salivary glands. Due to these sources, research by Cutando et al. (2007), is trying to explore the implications of melatonin in the oral cavity, in addition to its physiologic anti-oxidant, immunomodulatory and oncostatic functions at systemic level that may be receptor dependent or independent. Recently, certain in vivo studies by Shimozuma et al. (2011), detected the secretion of melatonin from salivary glands further emphasising its local activity. Thus, within our confines the effects of melatonin in the mouth are reviewed, adding a note on therapeutic potentials of melatonin both systemically and orally.

Subgingival applications of various chemotherapeutic agents have been used as an adjunct to nonsurgical periodontal treatment and preventive periodontal therapy. Their use in regular clinical practice, however, is less, perhaps due to concerns about clinical success or probably due to a lack of knowledge of their effectiveness or cost. The aim of this systematic review is to obtain overall quantitative estimate of effectiveness of subgingival irrigation (SI) in the treatment of chronic periodontitis.A literature search of electronic database was performed for articles published through December 31, 2014, followed by manual search of dental journals. Randomized controlled trails (RCTs) assessing the effect of SI as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis evaluated by changes in the clinical and microbiological outcomes were included.This literature search yielded only two randomized, placebo-controlled studies that evaluated the efficacy of SI as an adjunct to SRP in patients with chronic periodontitis. The studies were methodologically not perfect (in terms of mediocre quality) with a risk of bias to come to any final conclusions to be reached. These studies didnt clearly mention about randomization, allocation concealment, blinding, dosage and formulation of irrigants, severity of periodontal disease, patient-centered outcomes and results data.Due to insufficient evidence supporting the efficacy of SI as an adjunct to SRP in treating chronic periodontitis, more rigorous scientific research is required to assess the efficacy of SI as an adjunct to SRP in the treatment of periodontal diseases.

A 12-year-old girl reported for a routine dental checkup. Radiographic survey disclosed the presence of two developing structures resembling premolars one on either side of the mandible in premolar region, which were of supplemental type and surgical removal of supernumerary premolars facilitated eruption of the left second premolar. On six months follow-up, there was radiographic evidence of another supernumerary premolar in the left side of mandible that is left in situ, patient is on regular follow-up. This emphasizes the importance of thorough clinical and radiographic examination, early diagnosis and follow-up of the developing dentition in children. The patient has been followed-up from the age of 12 year to 17 year. This paper describes a case of recurrent supplemental supernumerary premolars in the mandible along with review of literature.

Animal studies have shown thyroid dysfunction affects salivary gland functioning, however conclusive human studies are lacking. We sought to assess the qualitative and quantitative changes in saliva among subjects with thyroid dysfunction prior to and following treatment.A longitudinal observational study of 153 newly diagnosed subjects who had hypothyroidism (n = 107) or hyperthyroidism (n = 46), aged 18-45 years, fulfilling the inclusion/exclusion criteria was conducted. Analysis of salivary parameters (stimulated salivary flow rate (SSFR), pH and buffering capacity) was performed at diagnosis (baseline), on attaining euthyroid state and 3 months thereafter.Subjects were 86% females, and at baseline 13% of subjects had hyposalivation. Mean SSFR, pH, buffering capacity as well as percentage of hypothyroid subjects having normal salivation increased following thyroid treatment.Thyroid dysfunction affects salivary gland function. Subjects with chronic hyposalivation should have thyroid function assessment if the known established causes are excluded.
