Dentistry Without Drill

The bravest among us feels terrified when hearing noise of a drill in dental office. Nowadays, there is a new drill-free dental technique which is used to remove dental caries as well as for other dental treatments; this technique is called Air Abrasion. The main idea of air abrasion is to utilize a mini sandblaster instrument which can spray the caries away. During the procedures of air abrasion, your dentist will aim a fine stream of particles (which are made of silica, aluminum oxide or baking soda) towards carious lesion of the tooth; compressed air or a gas which runs through a special hand-piece will push the particles towards surface of the tooth, the fine stream of particles will strike caries particles and remove them away.
teeth drillThough air abrasion technique is completely safe, some precautions must be made during it, including:
1.You must wear eye protectors to prevent your eyes from spray irritation
2.The dentist must use rubber dam to prevent from swallowing debris
3.A protective resin must be applied on the neighboring teeth and gum to protect them
4.All debris and particles must be suctioned to prevent you from breathing them into your lungs
In comparison with traditional drilling technique, air abrasion has many benefits, including:
1.Air abrasion produces no heat, no noise, no pressure, and no vibration.
2.Air abrasion limits the use of anesthesia in dental treatment, especially in simple cavities.
3.Air abrasion preserves the integrity of the remaining tooth structure
4.Air abrasion technique involves less moisture; this is an advantage when using tooth colored restorative materials, like composite and glass ionomer
5.Air abrasion restricts tooth chipping or micro-fractures
6.With air abrasion, the dentist can easily operate in many cavities during a single visit
7.The procedure of air abrasion are uncomplicated and rapid
While the disadvantages of air abrasion technique are:
1.Air spray in air abrasion technique sometimes causes sensitivity and pain to prepared tooth
2.Air abrasion can’t be used in deep cavities as it dangers the pulp
3.Air abrasion is only indicated in simple cavities which are confined to surface of the tooth
4.Composite filling material is the only type of filling materials used following air abrasion technique, as prepared cavities for amalgam filling need drill-cuts to retain amalgam restoration
cavity amalgamThere are many other uses of air abrasion technique; it can be used to remove old composite filling material, prepare surface of the tooth to receive sealants or bonding, and remove superficial tooth stains.
If you are dental phobic with minimal caries, then you are the best candidate for air abrasion.

How to use digital X-ray Or RVG with Apple iPad , iPhone. The Kodak RVG 6500

iPad Innovation is the key to development and dentistry is not an exception.First there was no radiograph then came conventional radiograph then came high speed radiograph and Digital radiograph or RVG  and now Apple iPad. You will say ( What ! an iPad?)  yes an iPad. It's an innovation by Apple inc.which has been accepted by medical and dental field warmly.I have discussed How to upgrade your dental practice with Apple iPad in earlier post and written about the change this gadget can bring.You can check  10 free iPad application for dentists Today in Digital Radiograph or RVG we shoot an X-ray few moments later it appears on the computer screen and then you interpret it and discuss it with your patients. Now Kodak have made a RVG system which is iPad compatible and if you have an iPad or iPhone you can see and review this X-ray image directly on your gadget write reports and save it. You must have Two thing for it. 1.RVG Mobile software in your iPad...

The Calla lilly prep in endodontics !!

During patient treatment, the clinician needs to consider many factors that will affect the ultimate outcome. In simple terms, these factors can be grouped into 3 categories: (I) operator needs, (II) restoration needs, (III) the tooth needs. (I)The operator needs are the conditions the clinician needs to treat the tooth. (II) The restoration needs are the prep dimensions and tooth conditions for optimal strength and longevity. (III)The tooth needs are the biologic and structural limitations for a treated tooth to remain predictably functional. The Cala Lilly is a flower and is the new model for composite preparations.

Articulator

Articulators    DEFINATION:  A Mechanical device that represents the temperomandibular joints and jaw members to which maxillary and mandibular casts may be attached to stimulate some or all of the mandibular movements. PURPOSES 1.   To  hold the maxillary and mandibular casts  in a determined fixed relationship. 2. Mounting of dental casts  for diagnosis treatment planning and patient presentation.   3.To simulate the jaw movement like  opening and closing. 4. Fabrication of  occlusal surfaces  for dental restoration. 5.  Arrangement of artificial teeth  for complete and removable partial denture.       USE      1. To diagnose the  state of occlusion in both  the natural and artificial dentition      2.   To plan the  dental procedures  based on the relationship between opposing natural and        ...
