How Can You Work in Australia as a Dentist

The dentist who has got his or her bachelor dental degree from a non-Australian institution needs to pass the skill assessment test/examination conducted by the Australian Dental Council and register themselves in Dental Board of Australia to practice as a general dentist in Australia or to get a job in public or private sector. 

The ADC test/examination is a screening examination to establish that dentists trained in dental schools which have not been formally reviewed and accredited by the ADC have the necessary knowledge and clinical competence to practice dentistry. 

Following are the steps, an overseas dentist needs to go through to qualify the ADC examination: 

Introduction to Third Molar Surgery: Part 3-Classification of Impaction

Oral Manifestations of Leukaemia

The oral manifestation of leukaemia can be summarized as follows.

In acute leukaemia- localized or generalized gingival hyperplasia is generally observed. It mainly affects the interdental papillae and the marginal gingiva. 

Contact Point/Area of the Teeth

The proximal contact point or the area refers to the surface point or area where the proximal surfaces of neighbouring teeth come in contact. Contact point/area is usually found in the occlusal one third of the natural crown of the most of the teeth.  

Can clothe masks be a substitute for N95 masks?

Can clothe masks be a substitute for N95 masks?  

The researchers at the University of Chicago performed a study to check the purification ability of the cloth masks. They made masks by joining one layer of tightly woven cotton sheet1 and two layers of polyester-spandex chiffon2, which is a fabric commonly used in evening gowns. These masks filtered out 80% to 90% spray particles ranging from 10 nanometres to 6 micrometres in diameter at normal human respiratory flow rate and volume.  

 

Diabetes Mellitus

Article written by 

Dr. Neha Rai 
MBBS, MD SR AIIMS Patna

Diabetes Mellitus refers to a group of common metabolic disorders that share the phenotype of hyperglycaemia and are caused by a complex interaction of genetics and environmental factors. It is very different from Diabetes Insipidus. Diabetes Insipidus is a syndrome characterised by the production of abnormally large volumes of dilute urine due to decreased secretion or action of Vasopressin, a hormone secreted by the posterior pituitary gland. 

The pathogenic process leading to hyperglycaemia is the basis for classification of diabetes mellitus into several types. Age or insulin dependence are no longer the criteria for differentiation. Type I and Type II are the two broad categories. In Type I DM there is destruction of pancreatic β cells and insulin deficiency resulting from autoimmune β cell destruction. Type II DM is characterised by variable degree of insulin resistance, impaired insulin secretion, excessive hepatic glucose production and abnormal fat metabolism. 

Bio-medical Waste Management

The biomedical waste management in India should be the burning and worrisome topic for the public as well as hospitals and health care service providers. Bio-Medical Waste (Management and Handling) Rules 2016 and further amendments in 2018 and 2019 have made enough provisions to handle all the biomedical wastes by any entity involved in anything related with health care provision. This includes, hospitals with only OPD facilities, hospitals with indoor facilities, blood donation camps, free health camps, medical services being provided in the field excluding the active war zones as well as the ships in the international water with Indian registration. 

The categorization of all biomedical wastes into four color categories namely yellow, red, white, and blue made the segregation easy and practical. It does not specifically say anything about the rules and regulations to be followed in reference to COVID-19. But when, the proper biomedical waste management protocols, standard precautions also known as universal precautions and the latest guidelines issued for the control of spread of Covid-19 by MoHFW are put together; we find ourselves equipped with enough tools to deal with all types of wastes and infections. 

We shall read more about the Bio-medical Waste (Management & Handling) rules 2016 and further amendments in 2018 & 2019 in further articles. 

Pontic Design in Prosthodontics

The pontic, \pŏn΄tĭk\, is an artificial tooth on a fixed partial denture that replaces a missing natural tooth, restores its function, and usually restores the space previously occupied by the clinical crown. An ideal correctly designed posterior pontic should have the following features.

  • All surface should have convexity with proper finish.
  • The contact with buccal contiguous slop should be minimal (pinpoint)) and with pressure free (modified ridge lap).
  • Buccal and lingual shunting mechanism should conform with those of the adjacent teeth.
  • Occlusal table should be in functional harmony with the occlusion of all of the teeth.
  • The overall length of the buccal surface should be equal to that of the adjacent abutment teeth or pontic.

The Pontic design can be classified into two types.

A. Pontic having mucosal contact

  1. Sanitary/Hygienic/Fish-belly and
  2. Modified sanitary type

B. Pontic with no mucosal contact     

  1.  Saddle/Ridge lap
  2.  Modified Ridge Lap
  3.  Conical
  4.  Ovate

 

Sanitary or Hygienic Pontic or Fish-Belly 

Sanitary pontic makes no contact with the edentulous ridge. It is made in an all-convex configuration, faciolingually and mesiodistally. The space between the pontic and the mucosa should be 2 or 3 mm[2]. It is most commonly used in mandibular molar replacement. It has the advantage of providing good access for maintaining hygiene with the disadvantage of poor esthetics.

Modified Sanitary

The tissue facing surface of the modified sanitary design pontic has a hyperbolic parabola. The pontic is designed as a concave archway mesiodistally while the under surface is convex faciolingually. It in indicated in molar replacement, provides access to undersurface for good hygiene, alongwith poor esthetics.

Saddle/Ridge Lap

It looks like crown of the tooth because it replaces all the contour of the missing tooth. It maintains a large concave contact with the underlying ridge and obliterates facial, lingual and proximal embrasures. Esthetic wise it provide best result but due to impossible access to under surface for cleaning, its use is limited for the replacement of maxillary incisors.

Modified ridge lap combines esthetics with easy cleaning, and makes contact with ridge tissues in a shape of ‘ T whose vertical arm ends at the crest of the ridge. This design is most commonly used in the area of the mouth that is visible during function, e. g. anterior teeth, premolars and sometimes maxillary molars.

Conical

Conical pontic design is mostly limited to the replacement of thin knife edged ridges in the non-display zone of the mouth. It has a convex surface with only touching the centre of the residual alveolar ridge. It helps maintain good hygiene with poor esthetics. Conical design in indicated for the replacement of molars.

Ovate

Ovate pontic design is the most aesthetically suitable appealing design that looks like emerging from the gingiva. When ridge resorption is corrected by ridge augmentation, ovate design appears to be emerging through gingiva just like natural tooth. it is indicated for the replacement of maxillary incisors, canines, and premolars. It has the advantage of best esthetics, negligible amount of food entrapment and easy cleaning. The disadvantage is the requirement of surgical preparation of the receiving site before prosthesis fabrication.
