Excision of epulis granulomatosa with diode laser in 8 years old boy

Introduction: Epulis granulomatosa is a lesion which grows from an extraction socket. It can be misdiagnosed with lesions of the same clinical appearance such as: foreign body or pyogenic granuloma, or as a herniation of the maxillary sinus. The most common treatment is surgical excision. Case report: The present article reports an Epulis granulomatosa which was removed with diode laser [810 nm] due to child's fear related to traditional surgical instruments and bleeding. Results and Conclusion: Lasers are useful for soft tissue surgery in modern dentistry, especially in relation to pediatric patients due to the rapid and regular wound healing without sutures

Treatment of ankyloglossia with carbon dioxide [CO[2]] laser in a pediatric patient

Laser surgery as an alternative for conventional surgical procedure has gained special attention. Using Carbon Dioxide [CO[2]] laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. A 12 years old boy with lingual frenum with indication for excision was referred to the laser department of Tehran University of medical sciences dental school. CO[2] laser was used with 10600 nm wavelength, 1.5 W output power, 100 Hz frequency and 400 micro sec pulse duration in non-contact mode. The result of using CO[2] laser was dry and bloodless field during operation, no post operative swelling, no pain or discomfort, with normal healing process. We suggest and stimulate the use of CO[2] laser for soft tissue surgery because of elimination of suture, convenient coagulation, time saving, patients' comfort and easy manipulation

Clinical approach of laser application in different aspects of pediatric dentistry

The application of laser in dentistry is considered as a favorable technique for patients due to its many advantages compare to other current methods. One of the main goals in pediatric dentistry is to provide the treatment as comfortable as possible without any risks for the care. Laser is being used in different pediatric dental conditions including caries detection, caries removal and cavity preparation, soft tissue surgery and in low level laser therapy applications. The application of current common lasers in dentistry resulted in less stress and fear in patients during dental procedures, also leading to more conservative non-invasive methods for soft and hard tissues with minimal discomfort and bleeding

[The effect of curing time and curing method on microleakge of conservative adhesive resin restorations: an in vitro study]

Using the conservative adhesive resin restoration [CAR] in uncooperative children lead to numerous problems because of being time consuming. The purpose of this study was to compare the microleakage of conservative adhesive resin restoration under separate curing and co-curing. In this experimental study, 120 intact premolar teeth were collected and 120 vertical grooves were prepared on them. Then the teeth were divided into four groups: group 1, separated curing of bonding agent, flowable composite and sealant; group 2, co-curing of all materials for 60 seconds; group 3, co-curing of all materials for 40 seconds and group 4, co-curing of all materials for 20 seconds. Then the specimens were thermocycled and immersed in basic fuchsin solution. The teeth were sectioned horizontally and dye penetration was evaluated with stereomicroscope. Date were analyzed using one-way ANOVA and Scheffe test. Mean value of dye penetration in groups 1, 2, 3, and 4 was 1.53 +/- 0.6, 2.06 +/- 0.6, 2.5 +/- 0.7 and 3.53 +/- 0.6, respectively. There was a statistically significant difference between group 1 and the other groups [P=0.0001]. Considering the problems caused by microleakage in conservative resin adhesive restorations, co-curing method should not be used. In the case of using co-curing method, 60 second curing time is suggested for sufficient polymerization

prevalence of bruxism and correlated factors in children referred to dental schools of Tehran, based on parents' report

Bruxism is defined as the habitual nonfunctional forceful contact between occlusal tooth surfaces. The aim of this study was to determine the prevalence of bruxism and correlated factors in children referred to dental schools of Tehran, based on parents' report. This cross-sectional descriptive study was conducted on 600 4-12 year-old children with a mean age of 7.4 +/- 2.4 years, who were referred to four dental schools in Tehran. After collecting information with questionnaire filled out by parents, chi[2] Fisher Test, Mann-Whitney and t-Test were used to analyze the data. The prevalence of bruxism was 26.2%. Bruxism begun in average at the age of 4.9 +/- 2 years. Also it occurred 2.6 times more in children who had a family history of bruxism [father-mother], compared to children who didn't have such a history. 87% of children with bruxism had a history of distressing events in their life, and 13% of children with bruxism did not report any history of distressing events in their life. In this study most common oral habit was nail biting. In study of parasomnias, drooling was the most, and snoring the least reported sleep disorder. Bruxism in children with drooling was twice more than in other children. The prevalence of bruxism in children with temporomandibular disorder was 63.6% and in children without TMD was 24.7%. Based on parents' report, 26.2% of children showed bruxism and there was a significant relation between bruxism and mother's job, family history, distressing event in life, parasomnias, especially drooling and sleep walking, TMD, hyperactivity, depression, acrophobia and lygophobia

[Evaluation of the microleakage of glass ionomer and resin sealant interface in conservative adhesive restoration [CAR]: an in vitro study]

Glass ionomer is used in conservative adhesive restoration [CAR] in order to release floride. The purpose of this study was to evaluate the microleakage of glass ionomer and fissure sealant interface in in vitro conservative adhesive restorations [CAR]. In this in vitro experimental study, a cavity with diameters of 5 and 3mm and depth of 1mm was prepared in the buccal surface of 21 human's intact premolar teeth. The prepared cavities were filled with glass ionomer and cured. Then another groove with diameter of 5mmx0.5mmx0.5mm was prepared adjacent to and in touch with the first box and filled with fissure sealant and cured. In the lingual surface of each tooth, a cavity with diameter of 3mmx3mm and depth of 1 mm was prepared and filled with flowable composite and cured. Another groove with diameter of 3mmx0.5mm was prepared and filled with fissure sealant and cured. Next, the teeth were subjected to thermolcycling [1000 cycle at 5 to 55[degree sign] c sealant-tooth, and composite-tooth was evaluated with stereomicroscope after being buccolingually sectioned. Results were statistically analysed using the Friedman and Wilcoxon tests. The rate of microleakage between glass-tooth was greater than glass-sealant and also the microleakage between glass-sealant was greater than the microleakage between composite-tooth and composite-sealant. The microleakage between composite-sealant was less than the others. According to the results of this study, it is better to use composite instead of glass ionomer in conservative resin restorations
