RESUMEN
Context: There are very limited data on the postsurgical formation of a mucogingival junction (MGJ) on teeth without its clinical detectability. Aims: The purpose of this study was to assess the formation and stability of MGJ on teeth without clinically detectable MGJ secondary to vestibular extension procedures for multiple adjacent teeth evaluated 6 months postoperatively. Settings and Design: This prospective interventional single-arm clinical study was conducted in the department of Periodontology, which was approved by the institutional ethical committee, MUHS, Nashik, and registered with the Clinical Trial Registry of India. Materials and Methods: This trial included 22 participants aged between 18 and 50 years of either gender, including teeth without clinically detectable MGJ along with adjacent teeth having detectable MGJs. The following clinical parameters were taken at baseline, presurgical, immediate postsurgical, 1-month and 6-month follow-ups: plaque index, gingival index, and position of MGJ. gingival margin level, probing depth, width of keratinized gingiva, width of attached gingiva, clinical attachment level, and vestibular depth. Statistical Analysis Used: Descriptive statistics included mean, median, mode, etc., and the inferential statistics done were analysis of variance along with post hoc Tukey and independent sample tests. Results: Apical shift of MGJ was observed from baseline to 6 months secondary to split-full-split repositioning MGJ with vestibular extension procedure, which was statistically significant (P < 0.05). The formation of MGJ was delineated by clinical and biochemical methods at sites with nondetectable MGJ. The coronal migration of MGJ at 6 months as compared to 1 month was not statistically significant (P > 0.05). The MGJ remained stable at 6 months postoperatively at detectable and nondetectable sites. Conclusion: Within the limitations of this study, we can conclude that there is a definite formation of MGJ in participants without clinically detectable MGJ treated with "split-full-split MGJ-repositioning vestibular extension procedure." The MGJ, which formed apically at a 1-month postsurgical visit compared to the presurgical position, remained stable for 6 months to 1-year follow-up period at both detectable and nondetectable sites.
RESUMEN
OBJECTIVE: The objective of the present study was to evaluate the clinical and radiographic outcomes of intrabony defects treated with decortication (intramarrow penetration) alone versus decortication combined with platelet-rich fibrin in periodontitis patients followed up for 6 months postsurgery. METHOD AND MATERIALS: A total of 46 intrabony defects from periodontitis patients with a mean age of 36.30 ± 6.10 years were randomly assigned into two treatment groups. The control group (n = 23) intrabony sites were accessed with simplified papilla preservation flap (SPPF) followed with debridement, decortication, and closure. The test group (n = 23) sites were accessed with SPPF, followed with debridement, decortication, platelet-rich fibrin placement, and closure. The clinical parameters Plaque Index, Gingival Index, probing pocket depth, relative attachment level, gingival marginal level, along with radiographic defect depth and defect width were recorded at baseline, 3 months, and 6 months postsurgery. Gain in clinical attachment level was the primary outcome, and probing pocket depth reduction and radiographic bone fill were secondary outcomes of the study. RESULTS: The Plaque Index and Gingival Index scores showed nonsignificant difference on intra- and intergroup comparison at baseline, 3 months, and 6 months. The probing pocket depth was 8.17 ± 1.56 mm, 6.65 ± 1.30 mm, and 5.26 ± 1.18 mm for the control group, and 8.17 ± 2.01 mm, 6.26 ± 1.42 mm, and 4.78 ± 1.28 mm for the test group, at baseline, 3 months, and 6 months, respectively. The relative attachment level was 8.83 ± 1.40 mm, 6.78 ± 1.31 mm, and 5.39 ± 1.16 mm for the control group, and 8.39 ± 1.62 mm, 6.96 ± 1.36 mm, and 5.48 ± 1.20 mm for the test group at baseline, 3 months, and 6 months, respectively. Statistically significant reductions were observed for probing pocket depth for the control (2.91 mm, P < .001) and test groups (3.39 mm, P < .001), as well as for relative attachment level for the control (3.44 mm, P < .001) and test groups (2.91 mm, P < .001). However, intergroup differences were nonsignificant for probing pocket depth and relative attachment level. The radiographic defect depth was reduced by 0.31 mm for the control and 1.57 mm for the test group. The radiographic defect width was reduced by 0.18 mm for the control and 0.83 mm for the test group. Intergroup statistically significant differences were observed at the 6-month follow-up (P < .001) for radiographic defect depth and width. CONCLUSION: Within the limitations of the present study, the results demonstrate statistically significant intragroup improvements in clinical outcomes with decortication alone and decortication combined with platelet-rich fibrin in the treatment of intrabony defects in periodontitis patients. The addition of platelet-rich fibrin did not improve the clinical results beyond decortication alone, and unacceptable postsurgery residual pockets were observed in both the protocols. Considering the small sample size, the addition of platelet-rich fibrin resulted in significant bone fill over and above that of decortication alone.

Context: The mucogingival junction (MGJ) is one of the important anatomical entities which mark the apical termination of attached gingiva, except that at palatal side. Its position is genetically determined like other organs and tissues in our body. There are certain anatomic aberrations such as abnormal teeth eruption or high frenal attachments and pathologies, such as periodontitis, leading to its absence. There are no studies on the prevalence of teeth having no clinically detectable MGJ. There is a resurgence of importance of attached gingiva, reflected by the definite presence of MGJ, through the field of dental implantology. Aims: We aim to evaluate the prevalence of teeth without clinically detectable MGJ on the buccal aspect of dentate alveolar processes. Settings and Design: This cross-sectional observational clinical study was conducted in the department of periodontology which was approved by the institutional ethical committee. Materials and Methods: Periodontally healthy as well as diseased patients of age 18-50 years were included in the study. The detection of MGJ was carried out by visual method, tension test, rolling probe method, and Lugol's iodine solution, and confirmation from any two methods was considered for the absence of MGJ. The etiology of MGJ absence (gingival recession, pocket till MGJ, trauma, abnormal frenal attachment, malposition of tooth, abnormal habits, severe abrasion, etc.,) was also evaluated. Statistical Analysis Used: Simple statistics in the form of averages and percentages were used for calculations. Results: A total of 130 subjects (3637 teeth) were examined out of which 32 (24.6%) subjects showed no clinically detectable MGJ. In all subjects, on an average, every subject has 28 teeth and out of the total 3637 teeth analyzed, only 91 (2.5%) teeth were without detectable MGJ. Conclusion: Almost 25% of the population may show a tooth or few teeth without a clinically detectable MGJ. The prevalence of teeth without clinically detectable MGJ per mouth is very low at 0.7 (approximately 1 tooth/subject).
RESUMEN
BACKGROUND: Which are the different ways of stabilizing connective tissue grafts (CTGs) for root coverage and gingival augmentation by means of placement of sutures? There are various defined and undefined ways of stabilizing CTGs depending on experience and personal preferences. Most of the techniques profess use of absorbable sutures in separate interrupted fashion (sutures at the corners of the graft wherever possible). AIM: This paper describes a new suturing method, "the lingually-tied horizontal mattress contouring suture," for stabilization of CTGs with or without epithelialized collar at the recipient site, for use with papilla retention and sparing techniques to treat marginal tissue recessions. METHODS AND MATERIAL: The suturing technique is described in detail. It can be indicated for good number of root coverage cases, with additional objectives of gingival augmentation, specifically developed for papilla sparing and papillary buccal de-epithelialization recipient site preparations. RESULTS: Over a period of last 16 years this suturing technique showed promising results in terms of graft stabilization and survival. The main advantage of this technique lies in the use of cost-effective nonabsorbable sutures that usually retain some amount of tension on the soft tissues longer. CONCLUSION: The primary objective of the suturing technique, per se, is to stabilize the CTG firmly along the contours of the root surface and to expedite a very close adaptation to the interdental soft tissues as well. The secondary objective of the article or publication is to disseminate the knowledge acquired through long periods of performance and observation for the benefit of the periodontal community as whole. Further validation is advocated.

BACKGROUND: Accidental ingestion of medium-to-large instruments is relatively uncommon during dental treatment but can be potentially dangerous. A case of BiTine ring ingestion is presented with a note on inefficient ring separation forceps. CASE DESCRIPTION: A 28-year-old male patient accidentally ingested the BiTine ring (2 cm diameter, 0.5 cm outward projections) while it was being applied to a distoproximal cavity in tooth # 19. The ring placement forceps were excessively flexible; bending of the beaks towards the ring combined with a poor no-slippage mechanism led to sudden disengagement of the ring and accelerated movement towards the pharynx. We followed the patient with bulk forming agents and radiographs. Fortunately the ring passed out without any complications. CLINICAL IMPLICATIONS: Checking equipment and methods is as important as taking precautions against any preventable medical emergency. It is the responsibility of the clinician to check, verify and then use any instrument/equipment.
