the era of technological advancements, one of the most significant innovation is the “LASER”. An acronym “LASER” stands for “Light Amplification by Stimulated Emission of Radiation.” Earlier, the term LASER was pronounced as “MASER” i.e. “Microwave Amplification by Stimulated Emission of Radiation.” LASER is a monochromatic and coherent light that is produced by the release of more photons which triggers a chain reaction. The laser compartment consists of six major components, which are important to understand for the production of light. LASERs have also been an integral part of dental sciences and helped to provide standard care particularly in the field of Prosthodontics

Purpose: Evaluation of implant overdenture retention at 23mm standard inter-implant distance using OT Equator and locator attachments. Materials and methods: Twelve completely edentulous patients were selected for this study. For all patients, conventional complete dentures were constructed. Mandibular dentures were replicated into stereolithographic implant placement guide using CBCT. Every participant received 2-implants in the anterior mandibular area with inter-implant distance of 23 mm. After the osseointegration period, the mandibular conventional dentures were converted into implant retained overdentures attached with Locator attachment for (group I) (six patients) and OT Equator attachments for (group II) (six patients). Retention was evaluated for conventional mandibular complete dentures (T0), 3-months (T3) and, 6-months (T6) after overdenture insertion using digital force-meter. Results: Results revealed that there was a statistically significant difference between the study groups representing mean retention force (P<0.05) except at T0 (baseline evaluation with conventional dentures) with higher mean values for group I (Locator attachment) than group II (OT Equator attachment). Conclusion: Regarding the limitations of this study: -Inter-implant distance of 23 mm for 2-implant overdentures could be considered a reliable modality for edentulous mandible. -Locator attachment may be preferable than OT Equator attachment regarding 2-implant overdenture retention at 23 mm inter-implant distance.

Background: Stroke had been the leading cause of death in industrialized countries, following cardiovascular disease and cancer. Aim and Objective: The present study aims to evaluate the fact that dental practitioners as health care providers ought to play their part in the early detection of patients at risk of having a cerebrovascular stroke. Materials and Methods: Initial study design consisted of 1000 panoramic radiographs (PRs), which were taken for patients visiting the department of Oral Medicine and Radiology. Two examiners reviewed all the radiographs. Sixty-one patients were found to have suspected carotid artery calcifications. Out of them, only 43 patients were subjected to Doppler ultrasound for confirmation of the carotid artery calcifications (CAC's). Results: Out of the 61 patients suspected of having carotid calcifications, 30 were male (49.2%) and 31 were female (50.8%) P value=0.844.Patients with age group between 51-61 had higher incidence of calcifications on orthopanograph (OPG). Mean age of the patients with calcifications on OPG was 56.67±SD of 10.15(p =0.004). Of the final 43 subjects, only 11 patients were confirmed to have positive carotid calcifications in Doppler ultrasonography study. Out of 11 patients, only 9 patients had atherosclerotic plaques that were not hemodynamically important and 2 patients had less than 50% carotid artery stenosis. Based on the Kappa value of 0.397, the level of agreement would be moderate with p value <0.001. Conclusion: Our study suggests that panoramic radiography can be a significant measure for detecting stroke prone patient. The role of Dental practitioners can be extended further, and overcome certain obstacles before panoramic radiography can be implemented as a new screening method for patients at risk of having a stroke.

Objective: Overall aim of this prospective, randomized, positive controlled, double-blind in vivo study was to identify the effects of a test dental gel containing 2.6% edathamil with an added carrier and permeability enhancer vs. a positive control dentifrice on periodontal health measures in patients with Stage II and III periodontitis.
Methods: In this prospective double-blinded, randomized study, 33 subjects were randomly assigned in a 1:1 ratio to brushing their teeth with either the test gel (LivFresh®, Livionex Dental Gel, Los Gatos, CA 95030) or the positive control toothpaste (Crest ProHealth®, P&G, Cincinnati, OH 45202).Full-mouth gingival index, modified sulcus bleeding index, and periodontal pocket probing depths were recorded for all teeth at baseline, and on days 90 and 180.Subjects brushed with the study material twice a day.
Results: The test dental gel reduced gingival inflammation and bleeding, as well as periodontal pocket probing depths significantly more than a control dentifrice.
Conclusions: In this pilot study in subjects with Stage II and III periodontitis, a test dental gel was found to improve gingival inflammation and bleeding, as well as periodontal pocket depths significantly better than a control dentifrice.

The treatment of periodontal diseases, mainly of their origin, with the most common clinical manifestation in form of gingival inflammation, is manifold and powerful, including: mechanical therapy, antibiotic, antiseptic and various approaches to treatment, which are recommended to be used within a short period of time. New therapeutic approaches have been proven as alternative treatment to conventional therapy, or in combination with conventional therapies, to reduce the number of periodontopathic pathogens in gingival sulcus. HBOT has a detrimental effect on periodontal microorganisms, as well as beneficial effects on the healing of periodontal tissue, increasing oxygen pressure in gingival pockets. Our study is aimed at reviewing the current published literature on hyperbaric oxygen therapy and focuses on role of HBOT as a therapeutic measure for the individual with periodontal disease in general and for the impact on the recovery of gingival inflammation. HBOT and periodontal treatment together, reduce up to 99% of the gram-negative anaerobic load of subgingival flora. HBOT, significantly reduces subgingival anaerobic flora. Clinical effects in 2-year follow-up of treated patients are sensitive. Reduction of gingival hemorrhage indexes, depth of peritoneum, plaque index, occurs in cases of combination of HBOT and detraction. Reduced load persists up to 2 months after therapy. The significant increase in connective tissue removal starts at the end of 2nd week, to achieve the maximum in week 3-6 of application. HBOT used for re-implantation, stimulates the healing of periodontal membrane, pulp, prevents root resorption, healing of periodontal lining tissues. HBOT, significantly reduces the hemorrhage index with 1.2 value difference, 0.7mm probe depth, reduces gingival fluid by 2. HGH exposure is increased by gingival blood flow, with a difference of 2 in measured value. The therapeutic effects of HBOT in the value of the evaluation index can be saved up to 1-year post treatment.

Background: Several methods have been employed for diagnosing inflammatory conditions including biomarkers, enzymes and various other clinical parameters. Dermatoglyphics is one such field which has gained entry in Forensic Medicine, Forensic Odontology and in General Medicine for diagnosing chronic inflammatory conditions. Periodontitis is a chronic inflammatory condition associated with destruction of periodontal tissues. This study aimed to assess the relationship between the fingerprint patterns and chronic periodontitis Methods: A total of 60 patients, belonging to both healthy and chronic periodontitis subjects were assessed by a commercially available fingerprint scanner. All the fingerprint images were assessed for the fingerprint pattern and the ridge count manually. The results were tabulated as percentage frequency distribution for the type of fingerprint pattern. The ridge count is shown as mean ± SD. Unpaired t test was applied to test for statistical significance. Results: The frequency distribution showed equal percentage of Radial Loop type of fingerprint pattern in subjects of both Health and Chronic Periodontitis. Statistical analysis showed Plain Whorl type of fingerprint pattern more significant in subjects having Chronic Periodontitis Conclusion: It was concluded that there might be a relationship between type of fingerprint pattern to the chances of a person having Chronic Periodontitis.

Oro-antral communication (OAC) may develop as a complication of dental extraction, trauma, infection or neoplasm. Buccal fat pad (BFP) has been increasingly used for the closure of OAC. However, some complications can be seen for pedicled buccal fad pad flap (PBFPF), such as infection, limitation in mouth opening, hematoma, and swelling. Nevertheless, there are no previousreports of subcutaneous emphysema after PBFPF. In this paper; a complication developed in the early period after use of PBFPF for closure of OAF was illustrated with special emphasis showing the strength of BFP against tension forces.

Background: Veneered all-ceramic restorations are associated with a high incidence of chipping and veneer delamination from the inner core. Monolithic all-ceramic crowns facilitate the fabrication process and minimize residual stresses between core and veneer. A new material,zirconia-reinforced lithium silicate(ZRL), Celtra Duo was recently introduced for fabrication of monolithic anterior crowns to overcome the aesthetic drawbacks of traditional zirconia and also to improve the strength of the lithium disilicate. Aim of the study: To examine the marginal fit of CAD/CAM: zirconia reinforced lithium disilicatand to evaluate it with Lithium silicate glass-ceramic crowns. Materials and methods: Thirty monolithic ceramic specimens will be fabricated and divided into THREE main groups; Group I: CAD/CAM ZLS Celtra Duo milled and polished, Group II CAD /CAM ZLS Celtra Duo milled and glazed & Group III: CAD/CAM Lithium silicate glass-ceramic (e.max CAD). For evaluation of the marginal fit 30 ceramic crown specimens ten specimens from each material(N=10), subgroups Ia, IIa, IIIa will be fabricated according to the manufacturers’ instructions and thermocycled to simulate one year clinical service. Marginal fit will be measured for the same specimens by using CBCT (Ia, IIa, IIIa). For evolution of marginal fit 30 ceramic crowns will be fabricated, ten crowns from each material (N=10), subgroups Ia, IIa, IIIa. Results: Will be arrangeand statistically analyzed.

Background: Lingual Frenulum connects the base of the tongue to the floor of the mouth. Tongue-Tie (Ankyglossia) is a congenital anomaly characterized by short lingual frenulum which restricts the mobility of tongue tip. Material and Methods: This study was done to determine the prevalence of ankyglossia among the population of North India. 500 subjects of both sexes aged between 18-70 years formed the sample size. Results: The results were obtained after classification of ankyglossia by Kotlow by measuring the length of free tongue and by measuring the length of lingual frenulum (indirect method) as suggested by Ruffoli et al. Inadequate tongue mobility was seen only in subjects with lingual frenulum<0.5mm. Conclusion: It should be stated that despite the reduced length the short lingual frenum is not always inelastic or fibrotic. It may allow a normal lingual mobility hence not necessitating a reduction intervention and also the effects of ankyglossia can be mitigated by the elasticity of the floor of the mouth and help the lingual mobility.

Objective: To describe the distribution of risk, diagnosis and pharmacological treatments for diabetes and hypertension after seven years among patients provided with opportunistic medical screening in a dental setting. Material and Methods: The initial screening’s 170 participants were asked to take part in a seven-year follow-up study. Data were collected through self-reported information in a written health declaration. Outcome measures: • Number of study participants who had passed away • Prescription of antidiabetics or antihypertensives • Changes in weight and height to calculate body mass index (BMI) Results: The follow-up study consisted of 151 participants. Twenty had passed away. The risk needs for medicating with antihypertensive drugs after seven years for those not receiving pharmacological treatment at the initial screening was 3.7 times greater (p=0.025 CI 1.2-11.3) for participants with a diastolic blood pressure (BP) ≥ 90 mm Hg (85 for diabetics) than for the others. The risk was 3.9 times greater (p=0.020 CI 1.2-12.6) for those with a systolic BP of 140-159 mm Hg and 54.2 times greater (p<0.0001 CI 9.8-300.3) for those with a systolic BP ≥ 160 mm Hg than for those with a systolic BP 140 mm Hg. There were no changes in BMI. Conclusion: At least one in ten cases of incorrect medication or undiagnosed hypertension may be identifiable through opportunistic medical screening
目的:描述在牙科机构提供机会性医学筛查的患者7年后糖尿病和高血压的风险分布、诊断和药物治疗。材料和方法:最初筛选的170名参与者被要求参加一项为期7年的随访研究。数据是通过书面健康声明中自我报告的信息收集的。结果测量:•研究参与者的死亡人数•抗糖尿病或抗高血压药物的处方•体重和身高的变化计算体重指数(BMI)结果:随访研究包括151名参与者。20人去世了。对于舒张压(BP)≥90 mm Hg(糖尿病患者为85)的参与者，7年后未接受药物治疗的抗高血压药物风险需求是其他参与者的3.7倍(p=0.025 CI 1.2-11.3)。收缩压为140-159 mm Hg的患者的风险是收缩压为140 mm Hg的患者的3.9倍(p=0.020 CI 1.2-12.6)，收缩压≥160 mm Hg的患者的风险是收缩压为140 mm Hg的患者的54.2倍(p<0.0001 CI 9.8-300.3)。BMI没有变化。结论:至少十分之一的不正确用药或未确诊的高血压病例可通过机会性医学筛查发现
