tips and tricks

Anterior tooth forms are simple to design when broken down into parts. As covered in previous blog posts we start the design with a rectangle. The length of the tooth is determined when considering the incisal edge and gingival margin positions. From this, the mesial-distal dimension can be judged when considering the ideal ratio of the tooth as it sits in the mouth. Once the position and size of the central incisor is defined, the other teeth can be designed more posteriorly. Canines are narrower than canines anatomically but tend to be the same length. Therefore then appear thinner in proportion. The rectangle defines the border of the tooth as viewed from the labial. From here, defining certain points on the borders of the rectangle will allow you to join the dots and define the form of the tooth (Figure1) . These points are: -Mesial and distal contact points which also define the incisal embrasures (the negative space that is formed between the incisal edge and interproximal sur

I would rather have less interfaces and composite resin only sealing the tubules. You could probably use a self etching primer and bond to seal the dentine which will remove sensitivity but ideally you pumice clean and etch enamel for an ideal long term bond. If you're going to do something then do it properly. Numb the patient up and restore in composite resin. If you want to temporise till a later time then bog it up in GIC till a later date. http://dental-tidbits.blogspot.com/2017/02/radix-entermolaris-and-radix-paramolaris.html I think i've seen 3radix teeth in 4 years. 1 was an incidental finding on a PA and 2 I had to extract. Of the ones I had to extract, one I saw before hand and it came out whole due to perio. The other I was lucky to notice a foreign body in the socket after I extracted

I was thinking about a situation in the car on the way home today. It was one of those: "well if they said that then I would say this, if they did this then I would do that" kind of moments. The scenario was that of an examination appointment where you've figured out the patient's goal is to improve their aesthetics or their function and in the course of your examination you know that it will be a full mouth rehabilitation. In any case this isn't something that you should plan or discuss on the spot. Therefore it is something that you should take records i.e photos, models, bite and facebow to plan the case out. As to the extent that you inform the patient of the plan I would say something like: "well sir/madam, according to your goals as I understand them, we want to improve your aesthetics/function and to do this is requires quite complex and expensive work. At this moment I am not sure if it is possible to do in a way that will fit your budget and expect

Crown preparations are simple in concept in that they require a uniform reduction of tooth structure to allow enough room for indirect restorative material and the creation of a margin to finish the restoration. However, multiple aspects of this procedure can be performed poorly resulting in substandard results. Anterior teeth crown preps are unique due to the importance of aesthetics in this zone and their different form to posterior teeth. on one hand, anterior teeth tend to be longer than posterior teeth occlusogingivally which bodes well for their being sufficient wall height to provide retention form. On the other hand, their smaller buccolingual dimension means that it is more important to avoid overreduction in this dimension as the pulp and fracture resistance of the tooth can be compromised. Technical issues that can occur with anterior crown preps include: -Most commonly, there can be insufficient reduction of the tooth on the incisofacial third. This occurs when a margin
