Abstract- In young pediatric patient the endodontic management of immature non vital permanent teeth is a great challenge to dentist. There is difficulty in debridement and obturation as the walls of the root canals are frequently divergent and open apexes are present. Apexification is a technique to generate a calcific barrier in a root with an open apex or the sustained apical development of an incomplete root in teeth with necrotic pulp. The most commonly advocated medicament is calcium hydroxide although recently considerable interest has been expressed in the use of MTA. In this case series both calcium hydroxide and MTA were used successfully for apexification procedure in teeth with open apex.

Using the Erbium Laser to Remove Porcelain Veneers in 60 Seconds Minimally Invasive, Efficient, and Safe Glenn A
SCIENTIFIC SESSION SEATTLE 2013 Using the Erbium Laser to Remove Porcelain Veneers in 60 Seconds Minimally Invasive, Efficient, and Safe Glenn A. van As, DMD Dr. van As will be speaking at the 29th Annual AACD Scientific Session in Seattle, Washington, on April 26, 2013. The title of his lecture is “You Light up My Life: Lasers in Contemporary Esthetic and Implant Dentistry.” In this article, Dr. van As discusses how erbium lasers have the ability to quickly and safely remove all porcelain restorations. Abstract For more than 30 years, porcelain veneers have provided clinicians with a method for changing a patient’s smile almost instantaneously. At times, however, veneers require replacement due to caries, fractures, or leakage or simply because the patient is unhappy with the esthetic outcome. Erbium hard tissue lasers can be used to efficiently, safely, and predictably remove all porcelain restorations while also keeping them in one piece. In doing so, this new tool for removing porcelain restorations provides clinicians with an alternative to high-speed handpieces while preventing further iatrogenic damage to underlying tooth structure.

The Cosmetic Challenge of the Class 2 Division 2 Patient
The Cosmetic Challenge of the Class 2 Division 2 Patient Rick DePaul, Jr., DDS Author, Powerprox Six Month Braces Technique The class 2 division 2 malocclusion can be a difficult one to achieve a great cosmetic result on. One characteristic of this malocclu- sion is retroclined upper central incisors. These teeth are also supererupted leading to a deep bite and less than desirable gingival architecture. The lateral incisors are often labially displaced as well (Fig. 1). All of these factors make for a very challenging cosmetic case. Many patients want quick results. This is one of the great bene- fits of placing porcelain veneers. You can get a great smile very quickly. Unfortunately, you cannot simply place veneers on the teeth in a division 2 case and get a great result. In order to improve the gingival architecture significant crown lengthening must be per- formed prior to placing veneers. Many times intentional endodon- tics must be performed as well due to the labial-lingual discrepan- Figure 1 cies of the upper incisors (Fig. 2). Retroclined central incisors, labially positioned lateral incisors, The use of orthodontics in these cases can help make these chal- deep bite, and poor gingival architecture are characteristics of a lenging division 2 cosmetic cases easy. My preferred method to treat division 2 malocclusion. these cases is the Powerprox Six Month Braces™ technique. This method allows you to quickly and conservatively treat these difficult cases. Some of the advantages of performing orthodontics instead of porcelain veneers alone on division 2 cases are: • Orthodontics opens the bite. • Less need for crown lengthening since you can greatly improve the gingival architecture with orthodontics. -

The traditional approach to handle cases with open apex DOI: 10.23804/ejpd.2017.18.04.03 is the multiple-visit apexification treatment with the use of calcium hydroxide (CH) as intracanal medicament [Seltzer, 1988]. The frequency of changes of CH from the root canal constitutes a controversial topic as there are studies Analysis of clinical that propose that a single placement of this medicament is enough to achieve predictable outcomes [Chawla studies related 1986], whereas others claim that multiple replacements of CH could lead to a more rapid formation of a calcified to apexification tissue barrier [Abbot 1998]. The time required for the calcified tissue barrier to form varies from 5 to 20 months techniques [Sheehy and Roberts, 1996] and seems to be influenced by several factors such as opening of the apex, frequency of intracanal medication replacement, age of the patient and the presence of periapical radiolucency [Mackie et al., ABSTRACT 1988; Finucane and Kinirons, 1999; Kleier and Barr, 1991]. -

A smile makeover using porcelain veneers is a com- monly requested cosmetic dental procedure and for good reason. Veneers can be used to correct a myriad of cosmetic dental problems such as discolored, chipped, worn, crooked or spaced teeth. Porcelain veneers, sometimes called porcelain laminates, are thin layers of dental porcelain used to replicate the natural look of healthy teeth. They are used to cover the front and sometimes side surfaces of teeth im- proving their appearance and function. Their strength and resilience are comparable to natural tooth enamel and is the material of choice for smile makeovers. Porcelain veneers resist stains and can be made to www.SmileArkansas.com • 501.819.8071 2 When bonded or adhered to natural teeth, porcelain veneers can create an amazing smile transformation. Smile makeovers using porcelain veneers have become a collaborative process involving input from the patient, treating cosmetic dentist and dental technician.
