Importância do tratamento estético periodontal na reabilitação protética

Gingival recession is a common deformity that affects a large number of people. This condition is frequently associated with esthetic complains and may lead to dental hypersensitivity. Thus, various surgical procedures have been proposed to provide root coverage. Since the 1950s, free and pedicle gingival grafts have been greatly used for treating gingival recession. However, after the 1985 Miller gingival recession classification, and with the development of other appropriated techniques that use subepithelial connective tissue grafts, gingival recession treatments have resulted in more predictable outcomes, especially with respect to Class I and II sites, i.e., in the absence of interproximal bone loss. This article reported the importance of aesthetical periodontal treatment in the prosthetic rehabilitation of a patient with a class I gingival recession with 3 mm of vertical extension in the superior canine. The treatment plan consisted of root coverage using subepithelial connective tissue graft (SCTG) associated with construction of new prosthesis.

Evaluation of dental restorations: a comparative study between clinical and digital photographic assessments

The aim of this study was to compare the efficacy of a direct clinical evaluation method with an indirect digital photographic method in assessing the quality of dental restorations. Seven parameters (color, occlusal marginal adaptation, anatomy form, roughness, occlusal marginal stain, luster, and secondary caries) were assessed in 89 Class I and Class II restorations from 36 adults using the modified US Public Health Service/Ryge criteria. Standardized photographs of the same restorations were digitally processed by Adobe Photoshop software, separated into the following four groups and assessed by two calibrated examiners: Group A: The original photograph displayed at 100%, without modifications (IMG100); Group B: Formed by images enlarged at 150% (IMG150); Group C: Formed by digital photographs displayed at 100% (mIMG100), with digital modifications (levels adjustment, shadow and highlight correction, color balance, unsharp Mask); and Group D: Formed by enlarged photographs displayed at 150% with modifications (mIMG150), with the same adjustments made to Group C. Photographs were assessed on a calibrated screen (Macbook) by two calibrated clinicians, and the results were statistically analyzed using Wilcoxon tests (SSPS 11.5) at 95% CI. Results: The photographic method produced higher reliability levels than the direct clinical method in all parameters. The evaluation of digital images is more consistent with clinical assessment when restorations present some moderate defect (Bravo) and less consistent when restorations are clinically classified as either satisfactory (Alpha) or in cases of severe defects (Charlie). Conclusion: The digital photographic method is a useful tool for assessing the quality of dental restorations, providing information that goes unnoticed with the visual-tactile clinical examination method. Additionally, when analyzing restorations using the Ryge modified criteria, the digital photographic method reveals a significant increase of defects compared to those clinically observed with the naked eye. Photography by itself, without the need for enlargement or correction, provides more information than clinical examination and can lead to unnecessary overtreatment.

Longitudinal results of a 10-year clinical trial of repair of amalgam restorations

The aim of this prospective, blind, and randomized clinical trial was to assess the effectiveness of repair of localized clinical defects in amalgam restorations that were initially scheduled for replacement. A cohort of 20 patients with 40 (Class I and Class II) amalgam restorations that presented one or more clinical features that deviated from the ideal (Bravo or Charlie) according to US Public Health Service criteria, were randomly assigned to either the repair or the replacement group—A: repair, n = 19; and B: replacement, n = 21. Two examiners who had calibration expertise evaluated the restorations at baseline and 10 years after according to seven parameters: marginal occlusal adaptation, anatomic form, surface roughness, marginal staining, contact, secondary caries, and luster. After 10 years, 30 restorations (75%) were evaluated (Group A: n = 17; Group B: n = 13). Repaired and replaced amalgam restorations showed similar survival outcomes regarding marginal defects and secondary caries in patients with low and medium caries risk, and most of the restorations were considered clinically acceptable after 10 years. Repair treatment increased the potential for tooth longevity, using a minimally interventional procedure. All restorations trend to downgrade over time.

Aplicação do enxerto conjuntivo subepitelial para recobrimento de recessões em dentes inferiores

Some regions of the oral cavity present anatomical conditions that seem to hinder the result of gingival recessions coverage. Thus, the aim of this case report was to present two surgeries for gingival recessions coverage in the mandibular teeth performed on the same patient with the follow-up of 24 months. Patient RP, 35 years old, male, Caucasian, nonsmoker, systemically healthy, sought care at the clinic of specialization course in Periodontics from the Araraquara Dental School (Foar-Unesp). His main complaint was the gingival recessions within the lower teeth 33, 34, 35, 43, 44 and 45. Besides the aesthetic nuisance, the patient reported occasional dentin sensitivity. For resolution of the case was referred to the technique of subepithelial connective tissue graft associated with a coronally advanced flap. After 2 years of surgery, it was observed an excellent root guards with significant aesthetic improvement of the case. It can be concluded that the subepithelial connective tissue graft technique was effective in covering of type class I gingival recessions of Miller, even in a region that provides a difficult procedure.

Recobrimento radicular para o tratamento de hipersensibilidade dentinária cervical persistente

Gingival recession has a high prevalence in the population. This alteration may promote several complications such as cervical dentinal hypersensitivity (HSDC), carious and non-carious cervical lesions, and cosmetic changes due to the increase of the clinical crown length. To treat HSDC there are several therapeutic possibilities that should aim to eliminate pain after external stimulus. Treatment of this alteration can be performed by a conventional or invasive procedure, depending on the clinical condition and patients' desires. In situations where aesthetics is not the main complaint and HSDC persists even after conservative procedures, it is possible to indicate a procedure to achieve root coverage in Miller's Class I and II recessions. The aim of this paper is to report a case where the HSDC was not eliminated by conventional methods, which was resolved only after performing a minimally invasive surgery that promoted total root coverage.

Recobrimento radicular por enxerto de tecido conjuntivo subepitelial

Gingival recession lesions are characterized by apical migration of gingival margin with consequent exposure of the root surface, which constitutes an aesthetic problem for the patient. Several surgical techniques have been used for the root coverage, and the technique of subepithelial connective gingival graft has greater predictability of root coverage and best aesthetic results with fewer postoperative side effects in relation to the epithelial free gingival graft. The goal of this case repot is to describe the technique of subepithelial connective tissue graft and demonstrates its result in a coverage Miller class I root recessions. After two years we can see excellent root coverage with significant aesthetic improvement of the case. The free subepithelial connective tissue graft technique was effective in coverage Miller class I root recession presented in this clinical case.

Evaluation of nasal obstruction in various sagittal skeletal deformity of jaws

Nasal obstruction (NO) is a common symptom present in 25% of the general population, which significantly interferes with the quality of life. The different facial profiles and malocclusion patterns could be associated with the degree of NO. In order to evaluate the nasal function in patients with different facial morphology patterns, the authors developed a prospective study in which 88 patients from a dentofacial deformities center were included. These patients were submitted to fibrorhinoscopy (Mashida, ENT PIII) with a 3.2-mm cannula under topical anesthesia to evaluate septal deviation, inferior and medium turbinates, and pharyngeal tonsils. The 88 patients included in the study were divided into 3 groups according to the classification of the facial profile, distributed as follows: 32 class I, 28 class II, and 28 class III; the data collected was statistically analyzed by analysis of variance and the results are shown. The patients included in this study presented similar prevalence of NO with the reduction of airway function efficiency. Although it was not a statistically different, the group II presented higher mean Nasal Obstruction Syndrome Evaluation scores.
