Specifically, use of the ovate pontic is among the most versatile and effective means for obtaining the desired results. Creating a gingival profile of an ovate pontic site allows the cervical third of the pontic to merge with the surrounding tissues thereby making it appear to have emerged from the alveolar ridge. Use of lasers offer several advantages over conventional procedures for preparation of ovate pontic site by providing sterile area, hemostasis, precise soft tissue contouring, less time consumption, and reduced postoperative pain. This report presents the use of diode laser in creating a gingival profile in a 43-year-old male patient for an ovate pontic design of a fixed partial denture prosthesis.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133586158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a precise and efficient method for esthetic rehabilitation as it allows the clinician to visualize and estimate discrepancy of orofacial and dentogingival tissues. This case report presents an interdisciplinary treatment approach for esthetic correction of a 20-year-old female patient who presented with a chief complaint of gummy smile. Through the application of digital smile designing principle, the necessary corrections for achieving a harmonic smile were accurately determined. Wax-up of the master cast was done accordingly. Gingival portion of the master cast was duplicated in clear acrylic resin. This temporary stent guided the gingival contouring which was done using soft-tissue diode laser. Diode laser was found to be safe and useful for soft-tissue management as it ablates soft tissues very precisely, and the wound healing is more favorable. We conclude that the DSD in combination with diode laser seems to be a useful tool to achieve a satisfactory esthetic result, especially in the management of esthetically demanding cases of gummy smile.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"10 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132364755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These oral mucosal lesions are usually symptomless and have little progression. Laser-assisted surgery is rampant nowadays with several bonuses including rapid hemostasis, being free of sutures, wound sterility, and negligible postoperative pain and edema. The objective of this report is to present a giant squamous papilloma over tongue in a pediatric patient. The lesion was excised with the help of a diode laser and the healing was uneventful in follow-up visit after 1 month. Giant squamous papillomas can rarely be found in children's oral cavity and laser can be used by clinicians to treat these kinds of lesions. It should be considered as an alternative to conventional surgery.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124880487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: Nine standardized incisions were performed in oral mucosa by scalpel, electrocautery, and diode laser. Specimens were classified into three groups according to tool used for surgical excision. Group A: Three specimens excised through a Bard-Parker (BP) scalpel blade no. 15c; Groups B and C included three specimens each excised through electrocautery and diode laser, respectively. Cut margins of biopsy specimens, adjacent peripheral mucosa were evaluated using light microscopy and histologic zones were identified, assessed: For epithelial changes, incision morphology, lateral tissue damage. Intra- and post-operative parameters assessed were the duration of surgery, bleeding, postoperative pain and healing. Results: Immediate hemostasis was seen with electrocautery and laser compared to scalpel (P < 0.011), mean time taken by electrocautery and laser was less compared to scalpel (P < 0.001). The analysis of regularity of incision and postoperative pain experienced by patients revealed a statistically significant difference (P < 0.01). Histologic damage was least with scalpel. The extent of degeneration was lowest with scalpel followed by laser or electrocautery (P < 0.05). Conclusion: Laser and electrocautery have upper hand over scalpel in relation to hemostasis, but have demerits such as lateral heat damage, tissue necrosis, delayed wound healing, and high cost. Even with advanced treatment modality, conventional scalpel treatment is better option in terms of precise incision, lower cost and faster reepithelization than laser and electrosurgery. Heat generating devices may not allow reliable histologic interpretations, particularly assessing margins of small biopsy specimens or malignant conditions.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122707585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This part (Part II) will focus on effect of root resection tools on root end in terms of Debris, smear layer, Dentinal tubules, Intertubular Dentin and Root Dentin - Gutta percha interface. Aims: To compare surface characteristics and morphological changes in erbium, chromium:yttrium-scandium-gallium-garnet (Er;Cr:YSGG) laser and bur-resected root ends in apicoectomy. Settings and Design: 5 W, 20 Hz, 50% air, 100% water, 300 mJ. Subjects and Methods: Forty freshly extracted human central incisors treated endodontically. Gutta-percha (GP) obturated teeth were resected apically 3 mm with 0° bevel. Twenty samples were resected with #702 TC Bur while the rest half were resected with Er,Cr:YSGG laser with 600 µm sapphire tip. All the samples were examined for debris, smear layer dentinal tubules, intertubular dentin and interface of GP, and root dentin on resected root surface under surgical operating microscope at ×16. Then, samples were fixed, dehydrated, and gold sputtered for observation under scanning electron microscope (SEM). Statistical Analysis Used: Data obtained were subjected to statistical analysis using Chi-square/Fischer exact test whenever required. Results: SEM observation revealed the absence of debris and smear layer with clean cut surface and patent dentinal tubules with exposed intertubular collagen, less gap (mean 9.95 µm), and least damage to apical adaptation of GP to root dentin walls in Er,Cr:YSGG-laser-resected root surface; while bur-resected samples revealed irregular, rugged root surface covered with debris, smear layer clogged dentinal tubules more gap (mean 20.98 µm) and damage to interface at GP, and root dentin walls. Conclusions: Er,Cr:YSGG-lased root surface provides better surface morphology, more conducive surface for regeneration of periodontium as compared to bur root resection.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126192524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
