You are more than welcome. The reference is Studevant's Art & Science of operative dentistry fifth edition, page number 350, the chapter entitled Instruments and Equipment for tooth preparation. A diagram on the same page clearly demonstrates that the small round bur number 0.5 is used to pin point the initial cavity outline. Then, an inverted cone is used to extend the cavity outline between two points, or more. Finally, a straight or a tapered fissure is used to carry out the final modifications on the cavity outline.

If you use the bitewing radiograph, first of all, you will be able to observe both maxillary and mandibular teeth (and their supporting structures) on the side of complaint and you will have the opportunity to recognize whether the bone loss is a localized finding or a generalized one. Second of all, the bitewing will enable you to see more with less radiation for the patient and for the operator. On the other hand, if you carry out multiple periapical (vertical) radiographs then you would waste one extra film and cause more radiation exposure. Finally, a peri-apical vertical radiograph is to be used secondary tp the bitewing in order to support/re-assure a clinical finding which was observed from the start. I hope that would be of help.

[Guest guest]

thanks for the explanation, i was just concerned about whether to use horizontal bite wing or vertical bitewing for furcation envolvement , as now we know the area of concern is that tooth with furcation envolvement , which has already limited the need of exposure to other area's . we will just take radiograph of that area. (I have understood this)I suppose horizontal bitewing will also show the furcation area thats why we don need a vertical bitewing . hope i am right?divi From: Khaled El-gammal <gammal_khaled@...> " " < > Sent: Friday, 23 March 2012 4:38 AM Subject: Re: bur
