Rehabilitation with implant-supported overdentures in total edentulous patients: a review
2013
Objectives: The main aim of this review article is to discuss implant-supported overdentures (ISOs) as treatment in edentulous patients. Besides, we will try to discuss among the different treatment options in such patients and to analyze their validity when ISOs are compared with other clinical modalities. At the same time, we will try to suggest clinical guidelines supported by current clinical studies. Material and methods: We performed a Medline search and review of pertinent articles on the mentioned subject from 1986 to 2011. As a searching strategy, we used the following words: implant-supported overdentures, attachment systems, Locator attachment, cantilever, fixed prosthesis. Resul…
Restore the natural: a review and case series report on reattachment
2014
Reattachment of the original tooth fragment to the fractured tooth helps in maintaining the tooth’s color, wear resistance, morphology and translucency in the restoration. This article describes the reattachment of fractured fragment using a fiber post and dual cure resin cement with a self-etching adhesive. Two young male patients reported with a complicated crown fracture of the right maxillary central incisor due a road traffic accident. The fractured fragments were loosely attached to the palatal gingival tissue, which was then surgically removed and preserved for the reattachment procedure. The fractured tooth segments were successfully reattached following fiber post cementation. Toot…
The craniofacial necrotizing fasciitis after a minor trauma in an elderly white woman
2014
The term necrotizing fasciitis /NF/ was probably first described by Jones in 1871 as “hospital gangrene”. NF, with its fast spreading from the local infection to massive necrosis of the underlying tissues, ie. superficial fascia and subcutaneous layers, is a potentially fatal disease, unless diagnosed early and properly treated. NF is more frequent in frail patients with chronic debilitating illnesses, immune deficiencies or from a poor social background. Sixty percent of NF cases occur in females. Here we present a case of necrotizing fasciitis of the head and neck region after a minor trauma (phenol blocks due to severe neuropathic pain) in an 82-year-old female with the history of trigem…
Significant association of MTHFD1 1958GA single nucleotide polymorphism with nonsyndromic cleft lip and palate in Indian population.
2014
Objectives: Nonsyndromic cleft lip and palate (NSCLP) is genetically distinct from those with syndromic clefts, and accounts for ~70% of cases with Oral clefts. Folate, or vitamin B9, is an essential nutrient in our diet. Allelic variants in genes involved in the folate pathway might be expected to have an impact on risk of oral clefts. Given the key role of methylenetetrahydrofolate dehydrogenase 1 (MTHFD1) in folate metabolism, it would be of significant interest to assess its role in NSCLP etiology. Study Design: The present study aims at examining the association between MTHFD1 1958G>A polymorphism and NSCLP risk by conducting a case-control study in south Indian population. Our sample …

Oral health care activities performed by caregivers for institutionalized elderly in Barcelona-Spain
2013
Objectives: To describe the frequency of brushing teeth and cleaning of dentures, performed by caregivers, for institutionalized elderly people. Methods: A cross-sectional study in a sample of 196 caregivers of 31 health centers in Barcelona. The dependent variables were frequency of dental brushing and frequency of cleaning of dentures of the elderly by caregivers. The independent variables were characteristics of caregivers and institutions. We performed bivariate and multivariate descriptive analyses. Robust Poisson regression models were fitted to determine factors associated with the dependent variables and to assess the strength of the association. Results: 83% of caregivers were wome…
Prevalence of root caries among elders living in residential homes of Bengaluru city, India
2015
Background: Among the various oral ailments which have been observed in elderly, root caries is a significant one. Tooth loss is chief oral health-related negative variable to the quality of life in elderly and root caries is the major cause of tooth loss in them. It has been reported about a third of older population bears most of the root caries burden, so the present study aimed to assess the prevalence of root caries among older individuals residing in residential homes of Bengaluru city India. Material and Methods: Elderly individuals aged 60 and above, residing in residential homes of Bangalore city, were included in the study. The study participants filled a questionnaire regarding t…
Acculturation and oral health status among Tibetan immigrants residing in Bangalore City, India
2011
Background: This study is the first of its kind conducted among Tibetans immigrants to Bangalore City, India to study the effects of acculturation on the oral health outcomes of less established group of individuals. Objectives: To determine the Acculturation and oral health status among Tibetan immigrants in Bangalore city and to assess the relationship between them. Materials and Methods: A random sample of 560 immigrants aged 18 years and above from different Tibetan centre of Bangalore city were included for the study. Acculturation was measured using modified Psychological-behavioral acculturation scale. Dental caries experience and periodontal status were recorded. Results: 49.1% of f…
Clinical Evaluation of self and professionally applied desensitizing agents in relieving dentin hypersensitivity after a single topical application: …
2013
Objectives: The objective of this study is to evaluate the efficacy of self and professionally applied desensitizing agents in relieving dentinal hypersensitivity after single direct topical application. Study Design: This was a randomized controlled trial conducted among 57 patients. 8% Arginine paste was self- applied by the subject and Gluma desensitizer was applied by investigator. Numeric rating scale was used to mea - sure hypersensitivity after tactile stimulus, Schiff scale was used for cold and air blast stimuli respectively. Scores were recorded at baseline, immediately, 15 and 30 days after the application. Friedman, Wilcoxon test as post hoc was used to analyze within group diff…
Mucocele de la glandula submaxilar: a propósito de un caso
2005
El mucocele es un término que incluye dos conceptos: el quiste de extravasación, que resulta de la ruptura del conducto de la glándula salival y el consiguiente derrame de la mucina en los tejidos blandos que rodean a dicha glándula, y el quiste de retención, que tiene su origen en la disminución o ausencia de la secreción glandular como consecuencia de la obstrucción del conducto de la glándula salival. No se puede considerar al mucocele como un verdadero quiste, ya que su pared carece de revestimiento epitelial. Este tipo de patología es muy común en las glándulas salivales menores ( sobretodo en las labiales), pero es muy poco frecuente en las glándulas salivales mayores y en concreto, e…
