RESUMEN
BACKGROUND: Dens invaginatus (DI), an unusual developmental anomaly is a challenge for the operating dentist with regard to its diagnosis and treatment. This case report presents the successful management of a Type-3b DI in a permanent maxillary lateral incisor associated with a large radicular cyst and communicating apico-marginal defect (Von Arx type IIb). METHODS AND RESULTS: A 19-year-old female patient reported pain and palatal swelling. During the clinical examination, tooth #12 exhibited tenderness to percussion, and presented a deep periodontal pocket depth (PPD) of 12 mm, along with grade I mobility. Radiographic examination revealed a large peri-radicular radiolucency with atypical tooth morphology. Cone beam computed tomography clarified the complicated root canal anatomy to be Type-3b DI associated with an apico-marginal defect. The case was managed successfully by non-surgical endodontic therapy followed by surgical intervention utilizing a guided bone regenerative (GBR) approach. Eighteen-month follow-up showed an asymptomatic and functional tooth with a significant reduction in pocket depth. The periapical radiographs showed continued healing of the osseous defect. CONCLUSIONS: The successful healing outcome of a challenging case, characterized by a complex DI morphology, a large peri-radicular lesion, a through-and-through defect, and a combined endodontic-periodontal apico-marginal defect was achieved through accurate diagnosis, treatment planning, and execution using contemporary endodontic and periodontal treatment techniques. The application of GBR techniques during the surgical phase of treatment may have contributed to the improved regenerative healing outcome in this case, which was initially considered prognostically questionable. KEY POINTS: Why is this case new information? Type-3b DI exhibits a complex root canal structure, each case displaying unique characteristics, necessitating a case-specific treatment plan. In this case report the Type-3b DI morphology was associated with a large peri-radicular, through and through defect and combined endodontic periodontal apico-marginal defect. The treatment approach involved incorporating guided bone regenerative (GBR) principles during the surgical phase. This case report contributes to the existing evidence on the diagnosis and successful management of Type-3b DI with a concurrent apico-marginal defect. What are the keys to successful management of this case? The successful management of a prognostically challenging case was achieved through a closely integrated multidisciplinary coordination between the endodontist and periodontist. Utilization of contemporary techniques and tools contributed to the successful management The use of three-dimensional radiological examination through cone beam computed tomography enabled a precise preoperative assessment, facilitating the formulation of a treatment plan for managing both the Type-3b DI morphology and the associated peri-radicular lesion. Employing GBR techniques in peri-radicular surgery may have assisted in the healing of through-and-through periapical defects with concurrent apico-marginal defects (Von Arx type IIb). What are the primary limitations to the success of this case? A complex root canal anatomy associated with Type-3b DI morphology A large peri-radicular through and through defect with concurrent apico-marginal defect. Difficulty in weekly and long-term follow-up of the patient.
RESUMEN
Purpose: Diabetes mellitus and periodontitis are inflammatory diseases, the severity of inflammation results in the progression and persistence of both the disorders and affects bones. Diabetic complications aggravate in diabetic subjects having periodontitis; similarly, diabetic patients are more prone to developing gingivitis and periodontitis. Periodontal and diabetic inflammation disturbs bone homeostasis, which possibly involves both innate and adaptive immune responses. The pathogenic processes that link the two diseases are the focus of much research and it is likely that upregulated inflammation arising from each condition adversely affects the other. RANKL/OPG pathway plays a prominent role in periodontal and diabetic inflammation and bone resorption. Method: This review article summarises the literature on the link between inflammatory cytokines and the prevalence of disturbed bone homeostasis in diabetic patients with periodontitis. An extensive search was done in PubMed, Scopus, Medline and Google Scholar databases between April 2003 and May 2021. Result: A total of 27 articles, including pilot studies, case-control studies, cross-sectional studies, cohort studies, randomized control trials, longitudinal studies, descriptive studies and experimental studies, were included in our literature review. Conclusion: Since RANKL/OPG are cytokines and have immune responses, regulating these cytokines expression will help control diabetes, periodontitis and bone homeostasis. The growing evidence of bone loss and increased fracture risk in diabetic patients with periodontitis makes it imperative that health professionals carry out planned treatment focusing on monitoring oral health in diabetic patients; bone markers should also be evaluated in patients with chronic periodontitis with an impaired glycemic state.
RESUMEN
INTRODUCTION: Studies suggest an association between poly-cystic ovarian syndrome (PCOS) and chronic periodontitis (CP), both being inflammatory conditions. However, insufficient evidence assesses the impact of this inflammation on bone metabolism and bone turnover markers (BTMs). The present study aimed to determine the association between BTMs, bone mineral density (BMD), and clinical periodontal parameters in PCOS women with CP. MATERIALS AND METHODS: Three groups, each with 40 newly diagnosed (1) PCOS+CP, (2) PCOS alone, (3) CP alone, and fourth group (n = 20) systemically and periodontally healthy females aged 18-30 years were included in the study. Full mouth clinical periodontal parameters, C-terminal telopeptides of type I collagen (CTX), bone alkaline phosphatase (ALP), BMD and 25-hydroxyvitamin D (VD) were recorded for all. RESULTS: Low BMD (0.89 ± 0.11 g/cm2), increased CTX levels (2.76 ± 4.64 ng/ml), decreased bone ALP levels (11.09 ± 6.86 ng/ml), higher VD levels (289.02 ± 168.28 nmol/l) and poor clinical periodontal status were observed in PCOS + CP females. BMD-spine showed weak positive correlation with CTX, bone ALP, VD (r = 0.02, r = 0.07, r = 0.15, respectively) in PCOS + CP group. ANCOVA depicted covariates had no confounding effect. Multiple regression model explained 21.0% for BMD-spine and 12.7% for BMD-femur of total variability signifying association with all measured parameters among all groups. CONCLUSION: Enhanced inflammatory thrust by periodontitis increases CTX levels and decreases bone ALP and BMD levels in women with PCOS. Screening PCOS women for periodontal disease and vice versa may have a direct bearing on overall bone health.

Background: This cross-sectional study investigated the bone mineral density (BMD) in type 2 diabetes mellitus (T2DM) subjects with or without chronic periodontitis (CP). Methods: A total of 120 subjects aged 35â55, divided equally into four groups: i) T2DM with CP, ii) T2DM without CP, iii) CP alone, and iv) healthy patients, were included in this study. Clinical parameters like plaque index (PI), gingival index (GI), and probing pocket depth (PPD) were recorded. All the participants were evaluated for blood sugar levels using glycated hemoglobin (HbA1c) and BMD by Hologic dual-energy x-ray absorptiometry (DEXA) scan. The association of BMD with clinical periodontal parameters and HbA1c in all groups was investigated using linear correlation analysis (r). Results: The mean value of BMD (0.9020±0.0952 g/cm2) was lower in subjects with both T2DM and CP compared to T2DM and CP alone. BMD was weakly correlated with all the clinical periodontal parameters; a positive correlation was observed between BMD and GI in the T2DM and CP group (r=0.405, P=0.026) and the CP group (r=0.324, P=0.081). A weak positive correlation was observed in BMD and HbA1c in the T2DM group (r=0.261, P=0.13), T2DM and CP group (r=0.007, P=0.970), with a negative correlation to HbA1c in the CP group (r= -0.134, P=0.479). Conclusion: Diabetes mellitus impacts clinical periodontal status and bone mass, and the effect is accentuated when chronic periodontitis is present. Based on the present study, BMD is associated with T2DM and CP, but a weak correlation was observed between BMD and HbA1c and clinical periodontal parameters.
RESUMEN
Esthetic rehabilitation of edentulous site with horizontal ridge deficiency presents as one of the most challenging situations in implant practice. With the increase in popularity of dental implants, augmentation of the alveolar ridge and soft tissue has also become a routine procedure in most of the cases. Although hard-tissue augmentation is performed by other specialists also, a periodontist needs to master the skills of soft-tissue management to deliver esthetic and functional results in implant-supported prostheses. This case report presents a single-staged ridge split approach using piezoelectric surgery with simultaneous implant placement followed by connective tissue grafting at second-stage surgery. Single-staged segmental ridge split technique not only reduces the total treatment duration but also the surgical morbidity for the patient. A subepithelial connective tissue graft is strongly advocated around implants as it is highly predictable while ensuring better esthetic results in terms of tissue color, texture, and long-term stability of the surrounding mucosa.
RESUMEN
Necrotizing periodontitis is a distinct and specific disease characterized by rapidly progressing ulceration of the interdental gingiva and then spreading along the gingival margins and leading to acute destruction of periodontal tissues. Necrotizing ulcerative gingival lesions are common in developing countries because of poor nutritional status, poor oral hygiene and debilitating conditions. In the developed world it is mostly seen in patients with the HIV infections and other immune system dysfunctions. The exact etiology of the necrotizing lesions is still unknown; however a fuso-spirochaetal infection along with weakened host immune system seems to play a major role in the pathogenesis of these diseases. Presented is the case of acute necrotizing periodontitis in a 21 year old male patient with no systemic disease but a history of tobacco use (chewing and smoking) since 7 years. The patient was managed by conservative treatment followed by surgery for the correction of gingival defects.
RESUMEN
BACKGROUND: Instrumentation of the root surface, results in formation of a smear layer of organic and mineralized debris which serves as a physical barrier, inhibiting new connective tissue attachment to the root surface. The present study advocates the use of an endodontic irrigant MTAD (mixture of tetracycline, citric acid and detergent) as a root conditioning agent. The main aim of the study was to compare the root conditioning ability of an endodontic irrigant MTAD (mixture of tetracycline, acid and detergent) with 17% EDTA (ethylenediaminetetraacetic acid). MATERIALS AND METHODS: Sixty freshly extracted human single rooted teeth with confirmed periodontal involvement were selected for this study and decoronated. The apical third of each root was removed and the remaining root was sectioned longitudinally to produce a 6mm to 8mm long tooth section. The root surface was then instrumented by hand using a sharp Gracey 1-2 periodontal curette with 6-8 strokes per area to achieve a smooth glass-like surface. A total of 60 specimens were prepared which were randomly divided into three groups (n=20). Each group received the root conditioning treatments as follows: All specimens were prepared for SEM and scored according to the presence of smear layer. RESULTS AND CONCLUSIONS: MTAD removed the smear layer successfully from the root surfaces. The mean smear score for samples treated with Biopure MTAD was lower than those treated with EDTA, (p=0.04). MTAD can be used as a root conditioning agent with efficient smear layer removal ability and known antimicrobial and anticollagenase activity.
RESUMEN
Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itching or any deviation from normal sensation. Altered sensation and pain in the involved areas may interfere with speaking, eating, drinking, shaving, tooth brushing and other events of social interaction which will have a disturbing impact on the patient. Paresthesia can be short term, long term or even permanent. The duration of the paresthesia depends upon the extent of the nerve damage or persistence of the etiology. Permanent paresthesia is the result of nerve trunk laceration or actual total nerve damage. Paresthesia must be treated as soon as diagnosed to have better treatment outcomes. The present paper describes a case of mental nerve paresthesia arising after the start of the endodontic therapy in left mandibular first molar which was managed successfully by conservative treatment.
RESUMEN
AIM: To compare the effect of passive ultrasonic irrigation with manual dynamic irrigation on smear layer removal from root canals using a closed apex in vitro model. METHODS: The root canals of 45 freshly-extracted human single-rooted mandibular premolar teeth were prepared by the Pro-Taper rotary system to an apical preparation of F4 size. Prepared teeth were randomly divided into three groups; two experimental groups and one control group (n = 15) on the basis of the type of activation of final irrigation as follows: (a) Group A, 3% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA), no activation received; (b) Group B, 3% NaOCl and 17% EDTA, ultrasonic activation with a small file; and (c) Group C, 3% NaOCl and 17% EDTA, manual activation with a master gutta-percha point. The prepared teeth were decoronated and split into two halves longitudinally, and observed under a scanning electron microscope to assess the removal of the smear layer. RESULTS: In the apical-third region, the mean smear scores for groups B and C were significantly less than those of Group A (control group) (P < 0.05). CONCLUSION: Both activation techniques are important adjuncts in removing the smear layer, with manual dynamic activation being a simpler, safer, and more cost-effective technique.

INTRODUCTION: Acute gingival bleeding can occasionally be the only sign of systemic bleeding problems. The diagnosis and management of such conditions may challenge the skills of the dentist. CASE REPORT: The present report describes a case of severe, prolonged gingival bleeding in a 54-year-old woman as a consequence of Plasmodium falciparum malaria infection. Specific highlights are focused on the management of the patient with emphasis on early diagnosis of the disease so as to improve the prognosis. This case report also stresses that medical intervention to correct the underlying aberration of hemostasis is necessary for local dental measures to successfully stop bleeding. CONCLUSIONS: Acute gingival bleeding as a complication of systemic disease can be challenging to manage unless the underlying systemic cause is diagnosed. Therefore, the dentist must be aware of various systemic conditions that can lead to gingival bleeding. The present case report describes a patient with acute gingival bleeding secondary to Plasmodium falciparum infection.
