Treatment of gingival hyper-pigmentation with the Er,Cr:YSGG laser - Clinical observation and one-year follow-up
Drs Gizem Berk, Kubra Atici & Nuket Berk, Turkey
The colour of the gingiva is determined by several factors, including the number and size of blood vessels, epithelial thickness, quantity of keratinisation and pigments within the epithelium. Melanin, carotene, reduced haemoglobin and oxyhaemoglobin are main pigments contributing to the normal colour of the oral mucosa.1 Frequently, the gingival hyper-pigmentation is caused by excessive melanin deposits mainly located in the basal and supra-basal cell layers of the epithelium.2
Some aspects of the use of the Nd:YAG laser in periodontal therapy
Drs Talat Qadri & Jan Tunér, Sweden
Moderate forms of periodontitis are demonstrated in 50 to 90 % of adults with regional and age-based differences. Periodontitis destroys the integrity of oral mucous membranes and is one of the main reasons for tooth loss, especially amongst people aged 40 and older. Aggressive forms of periodontitis may result in advanced loss of periodontal attachment and alveolar bone, resulting in urgent need for prosthetic treatment for those individuals within a very short time...
Laser-assisted dentistry in the daily office routine: A “multi-wave” concept
Dr Kresimir Simunovic, André Scholtz, Switzerland
Since Einstein pictured the nature of light and therefore postulated the basics of the concept of laser over almost a century ago, a long and sometimes rebellious time of experimentation elapsed before we finally witnessed a rapide and wide expansion of this instrument of light across all fields of dentistry in the new century...
Smile enhancement with laser technology - Predictable and esthetic: A case report
Dr Hugh Flax, USA
With the esthetic zone being absolutely critical to a patient’s external appearance and inner emotions, orchestrating a bioesthetic result is mandatory. Too often, this is complicated when esthetic desires infringe on the health of the periodontal complex. This is often true when biologic width violations have occurred iatrogenically. Many factors may contribute to these failures, the two main culprits being intracrevicular margin location and overcontoured restorations...
Papillon-Lefèvre syndrome - New laser-assisted treatment method
Dr Maziar Mir, Dr Surena Vahabi, Dr Shahrzad Jalali, Dr Bahram Kazemi, Dr Susanne F. de Haar,Dr Gholam Hossein Ramezani, Prof Dr Friedrich Lampert and Prof Dr Norbert Gutknecht
Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder. Its reported incidence is one to four per million and both the sexes are equally affected.1 PLS is characterised by palmo-plantar hyperkeratosis, periodontopathy and premature loss of deciduous, as well as permanent dentition.2 Plaque and calculus deposits may be present, along with significant halitosis.3 It manifests between one to five years of age and the patient becomes edentulous in the early teens. Another component of PLS is asymptomatic ectopic calcification in the choroids plexus and tentorium,2 hearing loss, follicular hyperkeratosis and nail abnormalities.4
Er,Cr:YSGG laser for cavity preparation: A case presentation
Dr Ralf Borchers, Germany
In the early 1990s, cavity preparation by Er:YAG laser was an exercise in patience. Owing to the low peak power of the pulse and a slow frequency the cavity was finished in what felt like hours after starting the laser treatment. Today, short pulse length, high power and increased frequency lead to short treatment times, comparable with conventional mechanical treatment by burs. Nearly all kinds of preparation and caries excavation can be done without any anaesthesia if the dentist is familiar with his laser and the correct treatment options. The procedure itself is more comfortable for the patient because there is no pressure or vibration on the tooth owing to the non-contact mode of the treatment...
The use of the Er:YAG in laser-assisted periodontal surgery
Dr Avi Reyhanian, Israel
Periodontal diseases are some of the most widespread of oral pathologies. Chronic periodontitis, characterised by local inflammation owing to infection with pathogenic bacteria, destroys the supporting structures of the teeth including periodontal ligaments, cementum and alveolar bone. Untreated periodontal disease then leads to tooth loss because the attachment apparatus and tooth-supporting structures are destroyed. The goals of periodontal therapy are to arrest the progression of periodontal disease and regenerate those structures lost to disease. Since periodontal diseases are considered both chronic and destructive, the sooner diagnosis and treatment begin, the better the prognosis is for the patient.
Laser in daily practice use - The key to therapeutic and economic success
Prof Dr Frank Liebaug & Dr Ning Wu, Germany
Laser dentistry went through a rapid development within the last years. Today, the use of laser devices enhances the whole dental treatment range valuably and supports conventional as well as conservative therapies. So the practioner achieves more safety and a better clinical result can be obtained for the patient in a gentle way. In the following, the authors show different alternatives based on clincial case studies...
