Objective: Inflammatory pathogenesis is common to periodontitis and oral lichen planus. This study was conducted to assess and compare the periodontal status of patients with and without oral lichen planus. Method and materials: 108 patients comprising 54 with oral lichen planus and 54 age-matched systemically healthy participants without oral lichen planus were selected. Periodontal parameters, ie Plaque Index, Gingival Index, bleeding on probing, probing pocket depth, clinical attachment level, and periodontal phenotype were measured. Results: On comparing the test and control groups, statistically significant differences were observed in respect to Plaque Index (P = .00), Gingival Index (P = .00), and bleeding on probing (P = .00). A higher proportion of sites with deeper pockets was observed in the test group (P = .00). On comparison of various oral lichen planus subtypes, significant difference was observed in respect to Gingival Index (P = .00) and bleeding on probing (P = .00). A higher proportion of sites with deeper pockets (P = .01) and greater CAL (P = .00) was observed in the erosive/atrophic subgroup compared to the reticular group. However, the differences between the reticular (a less severe form of oral lichen planus) and control group in terms of Gingival Index (P = .94), Plaque Index (P = .05), bleeding on probing (P = .17), probing pocket depth (P = .56), and clinical attachment level (P = .23) were not statistically significant. Statistically significant differences were observed in terms of Gingival Index (P = .01) and bleeding on probing (P = .00) between thin and thick periodontal phenotypes in the oral lichen planus group. Statistically significant positive correlations in periodontal parameters with increased gingival involvement and severity were observed using Spearman rank correlation coefficient. Conclusion: Significantly greater periodontal inflammation in the test group means there is a risk of greater attachment loss in future. Thus, increased attention towards periodontal health in these patients might reduce the rate of disease progression. [ABSTRACT FROM AUTHOR]

Aim: To evaluate clinical and radiographic outcome of endodontic microsurgery in through‐and‐through periapical lesions at 1‐year and 5‐year follow‐up with adjunct use of platelet‐rich plasma (PRP). Methodology: Thirty‐two patients with large through‐and‐through periapical lesions were randomized in platelet‐rich plasma (PRP) group and control group. Two‐dimensional (2D) healing was evaluated with Molven's criteria and three‐dimensional (3D) healing with modified PENN 3D criteria. Healing at resection plane (R), apical area (A), buccal cortex (BC), palatal cortex (PC) and overall bone healing (B) was assessed using CBCT scans. The volume of lesion was measured using ITK‐Snap software. The analysis included comparison of 1‐ to 5‐year intragroup (Friedman test/McNemar test) and intergroup scoring (Chi‐square/ Mann–Whitney test). Logistic regression analysis was performed to determine the effect of various factors on healing at 5 years. Results: Out of 32 patients/59 teeth evaluated after 1‐year of endodontic microsurgery, 24 patients/44 teeth reported at 5 ‐ year follow‐up. Healing assessment with modified PENN 3D criteria revealed improvement in overall success rate of 66.7% at 1 year to 83.3% at 5 years, with no deterioration in any healing category. PRP group exhibited significantly better 3D healing than control group; both at 1 year (84.6% vs. 45.5%) and 5 years (100% vs. 63.6%). A significantly higher number of completely healed teeth were observed in PRP group than the control group at 5 years with respect to R, BC and B parameters. A volume reduction of 88% (91.4% PRP, 84% control) was depicted at 1 year and 94% (97.1% PRP, 91.1% control) at 5 years. None of the recorded factors including age, gender, size of lesion, preoperative swelling and sinus, histology of lesion, use of PRP, tooth location, preoperative buccal bone had significant effect on 3D healing at 5 years. Conclusions: This 5‐year study suggested improvement in 3D radiographic healing of large through‐and‐through periapical lesions from 1 to 5 years with no deterioration in any healing parameter in both control and PRP groups. The additional use of PRP led to significantly better healing in such lesions. RACB index using CBCT allows better estimation of healing at resected, apical and cortical plane over modified PENN 3D or Molven's criteria. [ABSTRACT FROM AUTHOR]

Objective: The study aimed to evaluate healing in apicomarginal defects with amniotic membrane (AM) using 2D periapical radiography and 3D cone beam computed tomography imaging. Method and materials: Thirty-four patients with symptomatic apical periodontitis and apicomarginal communication were allocated to either the AM or control group. Clinical and radiographic assessment was performed at baseline and at 12 months using Molven criteria, modified Penn 3D criteria, and RAC and B indices at resected plane, apical area, cortical plate, and combined apicocortical area, respectively. Results: There was no significant difference in the healing outcome in 2D imaging (93.3% control and 86.7% AM) and 3D imaging (80.0% control and 53.3% AM) between the groups. With RAC scoring, a greater percentage of unhealed cases was observed in cortical plate. Radiographic buccal bone formation in the 3D imaging was evident only in six cases. However, both the groups depicted significantly greater percentage reduction in the size of the lesion in 2D than the 3D analysis (AM group 91.69 ± 15.99 2D, 76.06 ± 47.62 3D, P = .020) and (control group 92.06 ± 14.36 2D, 85.12 ± 18.55 3D, P = .005). Conclusion: No significant difference in healing was observed between the AM and the control groups with the use of both periapical radiography and CBCT imaging. Despite good clinical healing and radiographic apical bone fill, buccal bone formation was not evident in 3D imaging in most of the cases. [ABSTRACT FROM AUTHOR]

Introduction: Tuberculosis (TB) affects 8 million new people every year, with developing countries under its strong clout. Although tuberculosis can affect any part of the body involving both soft and hard tissues; such an occurrence in the maxillofacial bones in the form of tuberculous osteomyelitis is relatively rare. Due to the rarity of the lesion and lack of sufficient documentation, its incidence can be expected to be more than what has been reported so far. Observation: So, here is a case of a 21-year-old male who presented with pain and swelling on the mandible, diagnosed as tuberculous osteomyelitis after an initial diagnosis of dentoalveolar abscess. Conclusion: As dentists and as oral medicine practitioners, it is of utmost importance for us to be aware about uncommon diseases affecting the jaws such as tuberculous osteomyelitis, which tend to mimic dental infections in some cases to prevent misdiagnosis and provide holistic care to the patient.
