Non-carious cervical lesions (NCCLs) with gingival recession require specific consideration on both aspects of hard and soft tissue lesion. In the restorative aspect, careful finishing and polishing of the restorations prior to mucogingival surgery is the critical factor contributing to success. Regarding surgery, assessment of the configuration of the lesion and the choice of surgical technique are important factors. The precise diagnosis and the choice of the proper treatment procedure should be made on the basis of both restorative and surgical considerations to ensure the successful treatment of NCCLs.

PURPOSE: This study examined the factors that can be associated with the appearance of the interproximal papilla. METHODS: One hundred and forty-seven healthy interproximal papillae between the maxillary central incisors were examined. For each subject, a digital photograph and periapical radiograph of the interdental embrasure were taken using a 1-mm grid metal piece. The following parameters were recorded: the amount of recession of the interproximal papilla, contact point-bone crest distance, contact point-cemento-enamel junction (CEJ) distance, CEJ-bone crest distance, inter-radicular distance, tooth shape, embrasure space size, interproximal contact area, gingival biotype, papilla height, and papilla tip form. RESULTS: The amount of recession of the interproximal papilla was associated with the following: 1) increase in contact point-bone crest, contact point-CEJ, and CEJ-bone crest distance; 2) increase in the inter-radicular distance; 3) triangular tooth shape; 4) decrease in the interproximal contact area length; 5) increase in the embrasure space size; and 6) flat papilla tip form. On the other hand, the amount of gingival recession was not associated with the gingival biotype or papilla height. In the triangular tooth shape, the contact point-bone crest distance and inter-radicular distance were longer, the interproximal contact area length was shorter, and the embrasure space size was larger. The papilla tip form became flatter with increasing inter-radicular distance and CEJ-bone crest distance. CONCLUSIONS: The relative position of the interproximal papilla in healthy subjects was associated with the multiple factors and each factor was related to the others. A triangular tooth shape carries a higher risk of recession of the interproximal papilla because the proximal contact point is positioned more incisally and the bone crest is positioned more apically. This results in an increase in recession of the interproximal papilla and flat papilla tip form.

Many factors have been implicated in the etiology of gingival recession, including faulty toothbrushing, the position of the tooth in the arch(malalignment), the presence of inflammation, frenal attachment, impingement of restoration margins, orthodontic treatment and trauma from occlusion. Among the many factors, this study was to evaluate the relationship of occlusion and gingival recession. 640 teeth without other etiologic factors of gingival recession were evaluated in 40 subjects aged 21-59 years. Only 1st, 2nd premolar and molar were included in this study. We recorded nonworking contacts, working contacts, cervical abrasion, sex, gingival recession and evaluated that relation of occlusion and gingival recession. The results of this study were as follows; 1. Teeth with nonworking contacts were significantly more gingival recession than teeth without nonworking contacts.(p<0.01) 2. Teeth with working contacts were significantly more gingival recession than teeth without working contacts.(p<0.01) 3. Teeth with cervical lesion were significantly more gingival recession than teeth without cervical lesion.(p<0.01) 4. Men's teeth were more gingival recession than women's teeth but it was not significant.(p>0.01)

Assessing the condition of the alveolar bone before and after orthodontic treatment is important. Recently, cone-beam computed tomography has been widely accepted as a useful tool for orthodontic treatment. Moreover, using a three-dimensional (3D) structural analysis software enables gathering detailed information and quantifying data. The aim of this study was to introduce various quantitative analyses performed before and after orthodontic treatment by using a 3D structural analysis software for evaluating the morphological condition of the alveolar bone of a patient with gingival recession around the canines.

Mucogingival surgery is a general term for periodontal surgeries that correct aberrant periodontal soft tissues. Conventional mucogingival surgeries with pedicle flap or autologous soft tissue graft for treatment of gingival recession and insufficient keratinized tissues are always related to disadvantages such as need for a second surgery site, limited supplies, and complaints for postoperative discomfort. In this regard, research and application of soft tissue substitutes have gained increasing attention. Various kinds of soft tissue substitutes, including acellular dermal matrix and xenogeneic collagen matrix, have been developed and applied to clinical treatment. This review aims to summarize advances in research of the characteristics and clinical effectiveness of several soft tissue substitutes and provide references for clinical application.

ABSTRACT
Using laser for treatment of dentin hypersensitivity (DH) have recently shown promising results
and better immediate reduction in pain scores. However, its efficacy and mechanism of action is
controversial. Thus, this study aimed to evaluate the effectiveness of diode laser compared with
sodium fluoride varnish in treating DH in patients with gingival recession. Eighteen patients with
Miller’s class I and class II gingival recession and hypersensitivity in at least two non-adjacent
teeth were included in the study. Test surfaces (n = 25) were treated with diode laser, whilst control
surfaces (n = 23) were treated with 5% sodium fluoride varnish. Visual Analogue Scale (VAS) scores
were recorded for air and tactile stimulus for both groups at baseline, 15 min, 1 month and 3 months
post-treatment. Results showed significant (p < 0.05) reduction in VAS scores at 15 min, 1 month
and 3 months compared with baseline in both test and control surfaces, with no significant intergroup
differences. However, the percentage reduction in DH was more in laser at all evaluation periods.
The use of diode laser and sodium fluoride varnish showed good immediate and prolonged results.
Further studies are needed to come up with more effective treatment methods.

PURPOSE: The subepithelial connective tissue graft(SCTG) has been proven to be a highly predictable treatment modality for coverage of gingival recession. This case report was performed to evaluate the effect of various root coverage procedures using SCTG on gingival recession. MATERIALS AND METHODS: Three patients presents with Miller's class I recession defect on the maxillary canine. Each other SCTG(coronally advanced flap, Bruno's Tech., envelope Tech.) were performed for root coverage. Clinical parameters assessed included recession depth, recession width, and keratinized gingival width. Measurements were taken at baseline and 2 months and follow up end. RESULTS: The average of root coverage was 4 mm(100% of the pre-operative recession depth) at the 2, 5 months examination. The average increase of keratinized tissue between the baseline and the 2 months amounted to 3.2mm. CONCLUSION: Within the above results, various root coverage using SCTG is an effective procedure to Miller's class I recession defect and patient could be satisfied aesthetic requirement.

Full-mouth disinfection (Fdis) completes the entire scaling and root planing (SRP) in one stage within 24 hours for the prevention of microbial recolonization from untreated sites and ecological niches. The aim of this study is to compare the clinical short-term effects of modified Fdis with those of the conventional SRP in the therapy of moderate and severe chronic periodontitis. Modified Fdis group (5 patients) received the entire SRP within 24 hours using chlorhexidine solution (0.1%) and conventional SRP group (5 patients) received SRP per quadrant at one-week intervals. Clinical parameters were measured at baseline, one month and three months after both therapies. The results of this case report were as follows: 1. There were considerable decreases in sulcus bleeding index and plaque index one month after Fdis. 2. The mean probing depth of single-rooted teeth decreased more in Fdis group than conventional SRP group after therapy and, that of multi-rooted teeth decreased similarly in both groups. 3. The mean probing depth decreased 1.77mm in case of initial probing depth of 4-6mm and it decreased 4.13mm in case of initial probing depth of > or = 7mm three months after Fdis. 4. There were the smaller increases in gingival recession together with the larger gains in attachment in Fdis group than conventional SRP group after three months. Within the limitations of this study, one could conclude that Fdis has beneficial clinical effects in the treatment of moderate and severe chronic periodontitis and further research would be helpful including more subjects during a longer period to confirm the beneficial long-term effects of Fdis.

10.A laser Doppler study of gingival blood flow change following periosteal stimulation.
The Journal of the Korean Academy of Periodontology 2003;33(2):139-147
The roots of teeth exposed by gingival recession, may be successfully covered by various type of gingival grafting procedures. Vascularization of the recipient site is an essential determinant of the grafts'survival during the first healing stages. It has been suggested that a procedure by which they stimulate the periosteum presurgically will induce the proliferation of neo-endothelium in the site to be operated. The purpose of this study is to evaluate the variations in the gingival blood flow during 4weeks after periosteal stimulation in patient scheduled to receive gingival grafts and to compare variations in the gingival blood flow between smoker and non-smoker. Laser Doppler Flowmetry(floLAB(R), Moor Instruments Ltd, England ; wave length = 780mm. Max. power =1.6mW) was used to measure the gingival blood flow. 112 sites of 68 male patients (32 smokers and 36 nonsmoker), aged between 23 and 48 years (smoker : 24-44 years, mean=32.6, non-smoker : 23-48 years, mean=28.5) were monitored for the blood flow. Gingival blood flow measured at before periosteal stimulation, 1-, 2-, 3-, and 4-weeks after periosteal stimulation from 10 a.m. to 2 p.m. The difference of blood flow in each measuring time, each measuring site and between smokers and nonsmokers were statistically analyzed by MANOVA. The results were as follows : (1) Blood flow stayed increased for 2 weeks, and then, it was a tendency to decrease(p<0.05). (2) There was no statistically significant difference of blood flow change between smokers and non-smokers. (3) The blood flow at middle site had lower than mesial and distal site during the measuring periods(p<0.05). The present study suggested that blood flow change following peirosteal stimulation was significant difference, thus periosteal stimulation before gingival graft might induce favorable results in gingival recession patient.
