Introduction <\/span><\/b><\/p>\n

In the present era, Clinicians are keenly searching for better techniques, instruments and materials that allow the delivery of superior dental treatment with better patient comfort. \u00a0Technologies like CAD-CAM restorations,\u00a0digitalradiography\u00a0and photography,\u00a0implantology, maxillofacial dentistry, etc are gaining tremendous amount of popularity by providing an efficient and beneficial alternative over the conventional dentistry. The use of lasers is one of these hallmark technologies that enables dentist to work faster, more precisely and more efficiently.1<\/sup> Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. Lasers work on the principle of stimulated emission theory proposed by Albert Einstein in 1917 based on the concept of spontaneous stimulated emission theory which was postulated by Neil Bohr in early 1900s.2<\/sup> Traditionally, lasers have been classified according to\u00a0the physical construction of laser.\u00a0(eg: gas, liquid, solid state or semiconductor diode),\u00a0the type of medium which undergoes lasing ( eg: Erbium: Yttrium Aluminium Garnet) (Er:\u00a0YAG) and the degree\u00a0of hazard to the Skin or eyes.3<\/sup> In hard tissue application, the laser is used for caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation and for diagnostic purposes, In soft tissue application,laser is used for incision, excision, ablation, wound healing, removal of hyperplastic tissue to uncovering of impacted or partially erupted tooth, photodynamic therapy for malignancies, photo stimulation of herpetic lesion. Use of the laser proved to be an effective tool to increase efficiency, specificity, ease, and cost and comfort of the dental treatment. 4<\/sup> Besides itsbenefits, laser has its own disadvantages such as relatively high cost of laser unit,specialised training and education on operations of laser, different lasers for different procedures,inability of erbium family of lasers to remove metallic and cast-porcelain defective restorations, disease transmission in immunocompromised patients by laser generated aerosols, harmful to eyes.2<\/sup><\/p>\n

The aim of this study was to create awareness of laser among dentists inTanjore, one of the cities of Tamil Nadu with the population of over 24 lakhs. There are about 60 dental clinics in Tanjorewhere more than 70 dentists are practicing. \u200bIn view of the increasing availability of new technologies in dental practices, the need for more education and training this survey was conducted to\u00a0assess\u00a0the\u00a0education level and knowledge about laser in dentistry among dentists in\u00a0Tanjore.<\/p>\n

Materials and methods<\/strong><\/p>\n

This cross-sectional, descriptive study was carried out among dentists in\u00a0Tanjore.A questionnaire consisting of 3 main parts was designed and administered to dentists in\u00a0Tanjore. \u00a0The first part of\u00a0questionnaire consists of 7 items regarding the\u00a0dentist\u2019s\u00a0dental laser education and training. The second part consisted of 34 items in 6 sections. \u00a0Each section contained\u00a0items related to use of laser in 5 different dental specialities. [oral\u00a0surgery (8 items),\u00a0Endodontics\u00a0(4 items),\u00a0Periodontics\u00a0(4 items), Operative dentistry (10 items),\u00a0Pediatric\u00a0dentistry\/orthodontics (4 items), in addition to\u00a0sometimes in laser production (4 items). The Third part contained of 19 items in 5 sections. [Advantage of laser, effect of\u00a0laser on dental tissues, expenditure of laser treatment, biggest\u00a0deterrant\u00a0in practicing laser dentistry, types of laser to have in practice]. The data were entered and analyzed statistically.Each correct answer was given score and these scores were taken to analyze their knowledge.The score between 1-14 were considered as the inadequate knowledge, 15-28 were considered ad the moderate knowledge, 29-42 were considered as the adequate knowledge.<\/p>\n

Results<\/strong><\/p>\n

This questionnaire was given to 70 dentists in Tanjorefrom which 28 dentists(17 male, 11 female dentists)came out with positive responses. The negative responses are mainly due to their busy schedule and unwillingness to participate in the study.96% of dentists were aware that lasers were used in dental practice. Only 35% of dentists had practiced laser dentistry before. \u00a0Most of the dentists had interest in dental laser. Table 1 also shows that\u00a0their\u00a0dental\u00a0laser knowledge obtained mainly in\u00a0Periodontics, Oral surgery and\u00a0Endodontics. \u00a0The most known laser types among them were\u00a0Nd: YAG, diode lasers.Regarding\u00a0dentist\u2019s laser\u00a0knowledge, Table 2, chart 2 shows the dentists responses of each item in each section and mean score of each\u00a0section. The best score was obtained in oral surgery followed by\u00a0periodontics\u00a0and\u00a0endodontics sections(10.87,10.75,10.5) respectively. The lowest was recordedin laser protectionfollowed by operative dentistry, pediatric\u00a0dentistry(8.75,8.9,9.25) respectively. The scores of all students for each itemis\u00a0presented in chart 1. The wellknown information among dentists about the dental laser is the lasers application in gingivectomy and crown lengthening.<\/p>\n

Discussion<\/strong><\/p>\n

Education at dental college is the most important source for dentists as they depend on the information provided in college. This study provides a general view about dental laser education and knowledge among dentists. This survey only assessed\u00a0some basic knowledge of dentists regarding uses, advantages, effects of laser.<\/p>\n\n\n\n

Many dentists reported that they had laser education in oral surgery followed by periodontics, endodontics. Similarly, high mean score on advantage of laser in each section was obtained on oral surgery followed by periodontics, endodontics. Hence this shows that more the education the dentists had, the more knowledge they gained about laser. This also shows that dentists mainly depend on their college for gaining knowledge related to the subject.5<\/sup><\/p>\n

Majority of dentists, reported that they\u00a0did not receive dental laser education during\u00a0their college study programs. Only few dentists had practiced laser dentistry but majority of dentists had interest in practicing laser.<\/p>\n\n\n\n

Most of the information about dental laser was provided in Periodontics, Oral Surgery, Endodontics due to the implementation of laser in calculus detection, soft tissue surgery, canal disinfection, drying of\u00a0pulp cavity.6,7<\/sup> Some information was given in pediatric dentistry\/ortho & operative dentistry.<\/p>\n

Laser systems existing in dentistry can be transferred in dental canals via fiber optics like Nd:YAG Argon and Diode lasers\u00a0 or by hollow tubes such as CO2 Er:YAG\u00a0 lasers, and by doing so benefit from biomechanical intra canal cleaning as well as bactericidal ability of laser radiation will be achieved. Nd:YAG was one of the first lasers to be used for canal disinfection.8,9,10,11,12<\/sup> Er:YAG laser has been considered the most promising for periodontal therapy mainly due to its property to ablate soft and hard tissue without major thermal side effects. There is extensive evidence in literature to prove the comparable calculus removal effect of Er:YAG lasers (Keylaser 1 or 2; Kavo, Biberach, Germany) to conventional root debridement. Keylaser 3 (Kavo, Biberach, Germany) is the only commercially available device, which combines calculus detection and removal in a feedback-controlled manner. The automated device contains a 655-nm InGaAs diode laser for calculus detection and a 2940-nm Er:YAG laser for calculus removal.13<\/sup><\/p>\n\n\n\n

Many applications of laser in dentistry were not familiar to dentists as these applications are recently reported in the literature and proved its efficiency. \u00a0Majority of dentists did not know about the uses of laser in operative dentistry\u00a0like dentin desensitization. \u00a0According to a systematic review which was done by Sgolastra et al laser therapy can reduce dentin hypersensitivity related pain, but the evidence for its effectiveness is weak, and the possibility of a placebo effect must be considered. A systematic review on the effectiveness of laser therapy in treating dentine hypersensitivity reported that laser therapy has a slight clinical advantage over topical medicaments in the treatment of dentine hypersensitivity.14,15<\/sup><\/p>\n\n\n\n

In addition, most of them were not familiar with its applications in pediatric dentistry such as behaviour management in children and etching enamel for orthodontics bracket placement. LF at a wavelength of 655 nm (nonablative with red light) can be used as an adjunct for disclosing occlusal caries in primary and permanent teeth and due to its high reliability, predictability and reproducibility, it decreases diagnostic errors.16,17<\/sup> Lasers can provide treatment without the need for needles and high-speed hand pieces causing less intra and post-operative discomfort to the children. Furthermore, there is less need for behavioural management therapies in case of lasers assisted therapy.18<\/sup> Laser etching is a successful etching alternative to acid etching. Laser etching provides a successful debonding of the brackets from the enamel surface without causing fractures.19<\/sup><\/p>\n\n\n\n

In laser protection, 67% of people are aware that skin and eyes should be protected while using laser. The eye damage caused by the laser includes retinal lesion, retinal burn, Cataract, aqueous flare, corneal burn. The skin damage caused by the laser includes excessive dryness, blisters, burns.20<\/sup><\/p>\n

Less bleeding is the most known advantage of laser among dentists as it may be due to general education knowledge about laser in dentistry. Most of the dentists know about the hemostasis effect on dental tissues as it may be due to\u00a0education of dentists about the use of laser in periodontics.21<\/sup> Most of the dentist felt that the dental laser treatment as expensive as it may be due to the High cost required to purchase equipment, implement technology and invest in required education.18<\/sup><\/p>\n

Majority of dentists felt that the cost of the laser unit as the biggest deterrant as it may be due to patients response about cost of laser treatment. Most of\u00a0the dentists like to have diode type of laser in practice as its most widespread use for soft tissue in medicine and dentistry.22,23<\/sup> The clinical applications of laser includes detection of caries and sub gingival calculus, photo thermal bleaching, root canal therapy, low level laser therapy, frenectomy, canal disinfectant.24<\/sup><\/p>\n

Conclusion<\/strong><\/p>\n

This study shows that most of the dentists had only moderate knowledge on laser and its applications in dentistry. This study concluded that only 14 %of dentists in Tanjore have adequate knowledge on laser and its applications. Eventhough laser has many advantages in the field of dentistry, its practice in Tanjore is less due to the lack of knowledge and cost of laser unit. Hence education should be given during their college study programs on laser to increase its implementation in the field of dentistry.<\/p>\n
