استفاده از سمان گذاری برای اتصال روکش به ایمپلنت به دلایل مختلف ازجمله مزیت های بالینی و حفظ زیبایی استفاده وسیعتری پیدا کرده است. با این وجود پروتزهای سمان شونده دارای معایبی همچون احتمال سمان اضافی و نشت آن به بافت های اطراف ایمپلنت، و در نتیجه ایجاد عوارض التهابی در این بافت ها می باشد. استفاده از تکنیک سمان گذاری خارج دهانی می تواند سمان اضافی را به حداقل برساند. بر این اساس در مطالعه آزمایشگاهی حاضر دو روش خارج دهانی (PIA (Putty Index Analogue و LBA (Light Body) و متد رایج سمان کردن داخل دهانی از نظر نشت مقادیر سمان اضافی هنگام قرار دهی روکش بر روی ایمپلنت مدل با یکدیگر مقایسه گردید.
مواد و روش هادر این مطالعه تجربی- آزمایشگاهی، ابتدا 30 فریم زیرکونیا روی سه مجموعه اباتمنت-آنالوگ برای سه گروه مورد مطالعه ساخته شدند. گروه کنترل که بر اساس سمان کردن رایج داخل دهانی انجام گرفت. گروه LBA که در آن از یک لایت بادی سیلیکون تراکمی استفاده گردید. گروه PIA که از یک پوتی سیلیکونی به منظور سمان گذاری استفاده شد. در هر گروه پس از انجام سمان گذاری، سمان اضافی اطراف حد فاصل محل اتصال اباتمنت-روکش به صورت دستی و با استفاده از اسکیلر دندانپزشکی برداشته و با ترازوی دیجیتال با دقت ±0.01 mg توزین شد.
یافته هامقادیر سمان اضافی در گروه کنترل 13/07± 85/23میلی گرم، در گروه LBA mg 555 /0 ± 1/70 و در گروه PTA mg 1/45 ± 7/11 گزارش گردید. میانگین وزنی سمان اضافی در گروه LBA و گروه PTA از مقادیر کمتری نسبت به گروه کنترل برخوردار بودند(هر دو گروه با 001/0 > P). این در حالی است که میانگین وزنی سمان اضافی در گروه LBA تفاوت معناداری با گروه PTA نداشت. (0/265 = P).
نتیجه گیریتکنیک های سمان گذاری خارج دهانی PIA و LBA در مقایسه با تکنیک سمان گذاری معمول در رستوریشن های مبتنی بر ایمپلنت منجر به کاهش قابل توجه سمان اضافی شدند.
کلید واژگان: سمان, روش سمان گذاری PIA, روش سمان گذاری LBABackground and AimCementation for attaching crowns to implants has found wider use due to various reasons, including clinical advantages and aesthetic preservation. However, cement-retained prostheses have drawbacks such as the possibility of excess cement and its leakage into the surrounding tissues of the implant, which can lead to inflammatory complications in these tissues. The use of the extra-oral cementation technique can minimize excess cement. Accordingly, in this laboratory study, two extra-oral methods, PIA (Putty Index Analogue) and LBA (Light Body Analogue), and the conventional intra-oral cementation method were compared in terms of the amount of excess cement leakage when placing a crown on an implant model.
Materials and MethodsIn this laboratory study, 30 zirconia frameworks were fabricated on three abutment-analogue sets for three study groups. The control group underwent the conventional intra-oral cementation method. The LBA group used a light body condensation silicone. The PIA group used a silicone putty for cementation. In each group, after cementation, the excess cement around the abutment-crown connection was manually removed using a dental scaler and weighed with a digital scale with an accuracy of ±0.01 mg.
ResultsThe excess cement in the control group was reported as 85.23 ± 13.07 mg, in the LBA group as 1.70 ± 0.55 mg, and in the PTA group as 7.11 ± 1.45 mg. The average excess cement in the LBA and PTA groups was significantly lower than in the control group (both groups with p value < 0.001). However, the difference in average excess cement between the LBA and PTA groups was not statistically significant (p value = 0.265).
ConclusionThe extra-oral cementation techniques, PIA and LBA, significantly reduced the amount of excess cement compared to the conventional technique in implant-based restorations, which may limit the adverse effects of excess cement on surrounding tissues..

کلید واژگان: پاکت پریودنتال, ژنژیوکتومی, عوارض بعد از جراحی, دردBackground and AimPeriodontal surgeries complications and related factors are one of the most important things that surgeons in each clinic should be aware of to prevent them. Therefore, the aim of this study was to determine and compare the frequency, severity and trend of complications after periodontal flap surgeries with and without ostectomy and related factors in the periodontics department of Tehran University of Medical Sciences.
Materials and Methodspatients in the periodontics department of Tehran University of Medical Sciences, who underwent periodontal flap surgery or gingivectomy, were included in this prospective study. The pain, swelling, and bruising levels were asked on the same day, one and three days later. At the follow-up session on the seventh day, the pain, swelling and bruising levels were asked again, the tenderness and swelling levels were recorded by the surgeon, and flap dehiscence and pus presence were assessed. The difference between the complications’ levels on different days and also the difference in their trends between different surgeries was measured by GEE test, alongside testing the association of background and surgery characteristics with the complications’ levels by Mann-Whitney and correlation tests.
ResultsThe pain and swelling means on days 0 and 1 respectively were significantly higher than other days. The trend of means for complications were not different between the two groups of flap surgery with and without ostectomy. Tenderness, swelling, flap dehiscence and pus were present in 31%, 31%, 1% and 0% of patients after one week, respectively.
ConclusionComplications after periodontal flap surgeries were uncommon, except for mild pain and swelling.

Background
Orthodontic treatment often leads to gingival hyperplasia, which may complicate oral hygiene and necessitate surgical interventions such as gingivectomy. This study compared the efficacy of ceramic burs versus scalpels in gingivectomy procedures for orthodontic patients, focusing on periodontal outcomes and pain.
MethodsThis case series describes six orthodontic patients with gingival hyperplasia. The patients were between 15-25 years and were non-smokers. They underwent gingivectomy using two
methodsceramic burs (NTI® Soft Tissue Trimmers) and traditional scalpels. Preoperative oral hygiene instructions were given, and intraoral photographs were obtained. Clinical measurements included the plaque index (PI), gingival index (GI), and bleeding index (BI). Bleeding, pain (using a visual analog scale), and periodontal indices were assessed at several time points postoperatively.
ResultsBoth groups showed significant improvements in gingival hyperplasia, PI, and mean GI. However, the ceramic bur group experienced lower postoperative pain compared to the scalpel group. One patient in the scalpel group required analgesics for pain management. The results highlighted the effective management of gingival hyperplasia with both methods but with a potential advantage in pain management for the ceramic bur group.
ConclusionThis study indicated that both ceramic burs and scalpels are effective for gingivectomy in orthodontic patients. Ceramic burs might offer a less painful alternative, although both methods effectively manage gingival hyperplasia. Further studies with a larger sample size and longer follow-ups are required to confirm the present findings and potentially recommend ceramic burs as a preferred method for gingivectomy.

Introduction
Complete healing of a gingivectomy wound usually takes between one and two months. To speed up this process, different topical medications have been reported. In addition, there are different studies assessing the efficacy of low-level laser therapy (LLLT) in terms of wound healing and pain relief subsequent to gingivectomy, yielding inconsistent outcomes. In the present study, we systematically reviewed the existing evidence in the literature to resolve the given conflicts.
MethodsWe searched for the studies published from inception to 1 April 2023 in Embase, PubMed, and Scopus databases without language limitation by the use of appropriate keywords. We included randomized or non-randomized clinical trial studies that appraised the efficacy of LLLT in pain reduction and wound healing in adult patients who underwent gingivectomy. We pooled the continuous data concerning the pain visual analogue scale and the healing index extracted from the individual studies to provide a standardized mean difference (SMD) with a 95% confidence interval (CI), using a random-effects model.
ResultsOut of 188 sources initially captured from the database search, six studies were ultimately included. Regarding wound healing, the LLLT group exhibited a significantly higher mean value of the healing index compared to the control group on days 3 (SMD, 0.93; 95% CI, 0.39 to 1.47) and 7 (SMD, 1.03; 95% CI, 0.49 to 1.57) post-surgery. Also, significant differences were noted in the postoperative pain reduction between the two groups on days 3 (SMD, -2.00; 95% CI, -2.48 to -1.51) and 7 (SMD, -2.44; 95% CI, -4.66 to -0.22) post-surgery.
ConclusionAccording to the present systematic review, LLLT could potentially be an efficient adjunctive treatment after gingivectomy for wound healing acceleration and patient pain alleviation.

Introduction
Available evidence suggests that the response of the intervened tissue is directly linked to the effects generated by the cutting instrument used. To determine the histological findings in gingival tissue margins excised through gingivectomies performed using 450 nm, 940 nm, and 980 nm diode lasers. The present study aimed to determine the histological findings in gingival tissue margins excised through gingivectomies performed using 450 nm, 940 nm, and 980 nm diode lasers.
MethodsGingival tissue samples were collected from 30 patients who had undergone gingivectomy procedures. Each study group comprised 10 patients who willingly provided their samples after providing informed consent. The visualization of histological findings was facilitated through Hematoxylin-Eosin staining. Additionally, variables related to pain and hemostasis were assessed during the intraoperative period.
ResultsThe incision quality was categorized as irregular across all three wavelengths. Histological examination of the epithelial tissue revealed the absence of carbonization and the preservation of cell morphology in over 50% of the resection margin in samples obtained with the 450 nm and 940 nm wavelengths. In the connective tissue, observations included carbonization, collagen coagulation, and basophilia, with the 980 nm wavelength demonstrating the highest percentage of samples displaying collagen coagulation in more than 50% of the resection margin. Conversely, the 450 nm wavelength exhibited the highest degree of preservation of the fibroblast structure.
ConclusionBased on a comprehensive analysis of the study results, it can be inferred that the 450nm and 940nm wavelength lasers tend to produce less thermal damage and better cell preservation when compared to the 980nm wavelength.

Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to provide better results compared with conventional treatments, a significant variation exists in the applied laser parameters such as different wavelengths and energy densities of laser. The objective of this study was to collect preliminary information about the type and parameters of surgical lasers and how to use them technically based on the available literature on this topic.
Materials and MethodsAfter initial screening of 152 potentially relevant articles identified through an electronic search, 44 articles were selected based on the eligibility criteria by three independent reviewers. The inclusion criteria included studies on the outcomes of periodontal high intensity laser therapy in humans published in English between 2013 and 2021 in journals indexed in PubMed Central, Science Direct, Wiley Online Library, Springer or Google Scholar.
ResultsThe results showed that diode, Nd:YAG, Er:YAG, Er;Cr:YAG and CO2 lasers had the highest efficacy for frenectomy, gingivectomy, and osteotomy with specific wavelength, power density, frequency, and pulse mode. Various lasers have been suggested for the abovementioned purposes, and the method of choice depends on the efficacy and availability of laser.
ConclusionThis study confirmed higher efficacy of different laser types compared with conventional treatments.

مقدمه
یکی از مسایل مهم در جراحی ژنژیوکتومی، کاهش دوره ی ترمیم زخم ها و درد بیماران طی این دوره است. یکی از راه های جدید، استفاده از لیزر کم توان بوده که به خاطر عدم وجود عوارض جانبی، تجهیزات قابل قبول و هزینه ی کم مورد توجه است. هدف از این مطالعه، بررسی اثر تابش لیزر کم توان بر تسریع بهبود زخم ناشی از جراحی ژنژیوکتومی بود.
مواد و روش هااین مطالعه از نوع کارآزمایی بالینی کنترل شده بود. در این پژوهش، 22 نمونه در 12 بیمار با هایپرپلازی لثه در نواحی قرینه که کاندید جراحی ژنژیوکتومی بودند، مورد مطالعه قرار گرفتند. بعد از انجام ژنژیوکتومی، به طور تصادفی یک ناحیه در هر بیمار تحت تابش لیزر کم توان دیود 660 نانومتری برای مدت 5 روز قرار گرفت و ناحیه ی دیگر به عنوان گروه شاهد بدون تابش لیزر باقی ماند. برای مشاهده ی لایه ی اپی تلیالی در نواحی جراحی، از محلول افشای پلاک (Mira-2-tone) استفاده شد، سپس فوتوگرافی تهیه و با استفاده از نرم افزار فوتوشاپ Adobe photoshop CS 6 2015، مقایسه ی مساحت زخم در نواحی تحت تابش و بدون تابش لیزر انجام شد. تجزیه و تحلیل داده ها با استفاده از آزمون های تی مستقل، تی زوجی، آنالیز واریانس و نرم افزار آماری SPSS نسخه ی 23 با سطح معنی داری (p value < 0/05) صورت گرفت.
یافته هامساحت زخم رنگی شده در روز جراحی و سه روز پس از آن، بین دو ناحیه ی تحت تابش و بدون تابش لیزر، تفاوت معنی داری نداشت، اما مساحت زخم رنگی شده در محل تحت تابش لیزر در روز هفتم و پانزدهم پس از جراحی، نسبت به گروه شاهد کم تر بود (0/001 > p value).
نتیجه گیریکاربرد لیزر کم توان، باعث افزایش اپیتلیزاسیون و بهبود زخم در روز 7 و 15 پس از جراحی ژنژیوکتومی می شود
کلید واژگان: لیزردرمانی با لیزر کم توان, ترمیم زخم, ژنژیوکتومیIntroductionOne of the most important issues after gingivectomy procedures is to shorten the wound healing period and decrease pain. One of the new techniques is the application of low-level laser, which has attracted attention because of the absence of side effects, appropriate equipment, and low treatment costs. This study aimed to evaluate the effect of low-level laser on accelerating the healing process after gingivectomy.
Materials & MethodsTwenty-two samples in 12 patients with gingival hyperplasia on their symmetrical teeth were included in this controlled clinical trial. After gingivectomy, 660-nm lowlevel laser was randomly applied to one side for 5 days. The contralateral side served as a control with no laser irradiation. The surgical areas were subjected to a plaquedisclosing solution (Mira-2-tone) to visualize the epithelium in the surgical area. Comparison of the surface areas between the LLLT-applied and control sites were made with Photoshop software after taking photographs. Data were analyzed with paired-sample t-test, independent-sample t-test, and ANOVA using SPSS 23. Statistical significance was defined at p value < 0.05.
ResultsThere were no statistically differences between the stained surface areas of the LLLTapplied and control sites immediately after surgery and three days after surgery. However, the LLLT-applied sites exhibited significantly lower stained areas compared with the controls on the seventh and 15th postoperative days (p value < 0.001).
ConclusionThe results indicated that LLLT might enhance epithelialization and improve wound healing after gingivectomy.

Journal of Dentistry, Shiraz University of Medical Sciences, Volume:19 Issue: 3, Sep 2018, PP 248 -252The pursuit of esthetic excellence has become a major goal in the dental treatment and orthodontic treatment. The beauty of the smile is not only constituted by the shape, position, and size of the teeth, but also based on the characteristics of the gingival tissue and conformation of the lips, which should be as harmonious as teeth. Gummy smile is one of the complaints of the patients, since such a situation can influence self-esteem and social relationships. The development of new more conservative techniques may provide a better therapeutic option than surgical procedures, such as the application of botulinum toxin, in the treatment of gummy smile. The purpose of this article is to present the case of a patient who presented dentogingival discrepancy and gummy smile, treated by resective gingival surgery and by application of botulinum toxin, optimizing smile harmony, and achieving improved self-esteem and quality of life. The application of botulinum toxin is an alternative less invasive, faster, safer, and more effective. Moreover, it produces harmonics and pleasing results when applied in target muscles, respecting the appropriate dose and type of smile. Therefore, the technique is a useful adjunct in the esthetic improvement of the smile and provides better results when combined with resective gingival surgery.Keywords: Gingival overgrowth, Botulinum toxins type A, Gummy smile, Gingivectomy, Dental esthetics

Idiopathic or hereditary gingival fibromatosis (HGF) is a relatively rare disease characterized by the enlargement of the gingiva, resulting in functional, esthetics and psychological disturbances. The degree of gingival overgrowth can be defined as: grade 0: no sign of gingival enlargement; grade I: enlargement confined to interdental papilla; grade II: enlargement involves papilla and marginal gingiva; and grade III: enlargement covers three quarters or more of the crown. This case report describes the case of a 16-year-old girl suffering from HGF with chief complaint of gingival swelling. Intraoral examination exhibited diffuse and grade III gingival enlargement in both jaws and also in both surfaces of buccal and lingual/palatal. Treatment included surgery (internal and external gingivectomy) in six sessions, and prescription of antibiotics and 0.2% chlorhexidine mouthwash. Moreover, gingivoplasty was performed in the esthetic zone of maxilla after performing all the surgeries in the mouth. The patient was under regular follow-up visits. The treatment outcomes after six months were satisfactory and no symptoms of recurrence were observed.Keywords: Gingival fibromatosis, gingival enlargement, gingivectomy
