Clinical outcomes, time span for healing of various ocular surface disorders with amniotic membrane: A prospective, an Indian study

Purpose: To study the clinical outcomes, time span of healing of various ocular surface disorders with amniotic membrane graft. Methods: A total of 41 patients, presenting to cornea clinic were included in the study and divided into five groups depending on the type of diagnosis: Group 1, with either >2 weeks of Persistent epithelial defect following cataract/retinal/glaucoma surgeries or Shield ulcers, Group 2 with >4 weeks of Non healing corneal ulcers, Group 3 with chemical injuries, Group 4 with Epithelial defects following keratoplasty, and Group 5 is the miscellaneous group. Results: The mean age of the study subjects was 50.0 years. Overall mean duration between clinical presentation and AMT was 23.59 (30.7) days, a median 16 days (IQR; 2?26 days). Failure rate was high in Group 5 (n = 3: 30.0%) and Group 2 (n = 3: 27.3%). Time taken for epithelial closure was slower in groups 1 and 5 patients. The average time taken for reabsorption of AMG was 14.98 days. The complications included repeat AMG was in four eyes (9.75%), and graft displacement was noted in four eyes (9.75%) required resuturing, three eyes required TPK (7.31%), and one eye underwent evisceration (2.43%) following severe corneal melt secondary to neurotropic ulcer. The mean log MAR visual acuity improved from 1.52 to 1.26 at the 3 months. Conclusion: Understanding on timespan for healing of ocular surface disorders with AMG is needed to assess the prognosis of the disease, preoperative counselling for repeat procedures, and the compliance with regard to follow up.

Epithelial ingrowth under LASIK flaps: tips and tricks for preventing recurrence!

Background: LASIK for refractive error correction has become a universal surgery. Despite its popularity, the estimated prevalence of traumatic flap dislocations in post?LASIK patients is 3.9%, and it is sometimes associated with epithelial ingrowth. The prognosis in such cases depends on the rapid surgical revision of the flap with the removal of the EI and perioperative steps to prevent Epithelial ingrowth (EI) recurrence in the future. Purpose: The video aims to display the steps involved in revising the flap, removing EI, and tips to prevent its recurrence. Synopsis: A 33?year?old post? LASIK patient presented with decreased vision, photophobia, and glare during the COVID pandemic in the right eye for 2 months. The best?corrected visual acuity was reduced to 6/60. The anterior segment revealed traumatic flap dislocation along with macro fold temporally and epithelial ingrowth. She underwent a successful flap revision surgery with no recurrence of epithelial ingrowth postoperatively. Highlights: A successful revision of a 2?month? old traumatic folded flap was performed along with the complete removal of EI. It explains the step?by?step approach to avoid the recurrence of EI in each step of the surgical revision of the flap. The video is self?explanatory and guides novice surgeons too

In majority, 65% of the cases fasciotomies were done within 48 hrs of electrical burn injuries. Conclusion: The results of the study concluded that younger generation is more prone to electrical burn injuries and males were majorly affected. Unsafe work areas and accidents are main reasons for injuries. High voltage affected the study population compared to low voltage. Amputations were required in fingers and below elbow. Early fasciotomy, repeated debridement's, definitive skin cover (SSG/flap) have helped in reducing the morbidity and improving the quality of life of the patient.

A novel transconjunctival, intrascleral, ab-externo, knotless, and double-flanged technique with 6-0 Prolene for iridodialysis repair

Small traumatic iridodialysis (ID) may be asymptomatic, but large ones usually cause polycoria and corectopia, leading to symptoms like diplopia, glare, and photophobia. The management of ID, including medical and surgical methods, depends upon the patient’s symptoms. Mild glare and diplopia can be treated either with atropine, antiglaucoma medications, tinted spectacles, colored contact lens, or corneal tattooing, but extensive IDs require surgical options. The surgical techniques are challenging due to the iris texture and the damage encountered during the primary surgery, the narrow anatomical workspace for repair, and the associated surgical complications. Numerous techniques have been described by several authors in the literature; each has its advantages and disadvantages. All the procedures described previously involve conjunctival peritomy, scleral incisions, and suture knots and are time consuming. Here, we report a novel transconjunctival, intrascleral, knotless, and ab-externo, double-flanged technique for repair of large ID with a 1-year follow-up

Lid wiper epitheliopathy in symptomatic and asymptomatic dry eye subjects

Purpose: Lid wiper epithliopathy (LWE) was stuided in symptomatic and asymptomatic dry eye subjects. This is the first such study to be conducted in the Indian population. LWE is a clinical condition associated with vital staining in the lower and upper eyelids on increased friction of the lid margin over to the cornea. Our aim was to study LWE in symptomatic and asymptomatic (control) dry eye subjects. Methods: Out of 96 subjects screened, 60 subjects were enrolled in the study and were divided into two groups, symptomatic and asymptomatic dry eye subjects, based on the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire and the Ocular Surface Disease Index (OSDI) scores. The subjects were examined to rule out clinical dry eye findings and assessed for LWE with two different dyes (fluorescein and lissamine green). Descriptive analysis was done and Chi?square test was used for statistical analysis. Results: A total of 60 subjects were enrolled in a study with a mean age of 21.33 ± 1.88 years, out of which the majority of LWE patients (99.8%) was seen in the symptomatic group than the asymptomatic group (73.3%); the difference was statistically significant (p = 0.00) and also clinically significant. LWE was found to be significantly higher in symptomatic dry eye subjects (99.8%) compared to asymptomatic dry eye subjects (73.3%). LWE severity was also found to be more (56.6% of grade 3) among symptomatic dry eye subjects compared to asymptomatic subjects (40% of grade 2). Conclusion: It is important to assess the lid wiper region (LWR) and treat LWE in routine clinical practice.

Infratentorial atypical choroid plexus papilloma in an adult: A case report and literature review

Atypical choroid plexus papilloma is classified as WHO (World Health Organization) Grade II subtype of choroid plexus tumor, and it has intermediate pathological features, prognosis, and clinical outcome rates between choroid plexus papilloma and choroid plexus carcinoma. These tumors are more common in children compared with adults and are usually located in the lateral ventricles. We present a case of an adult with atypical choroid plexus papilloma located in the infratentorial region. A 41?year?old woman underwent evaluation for headache and dull aching neck pain. Magnetic resonance imaging (MRI) of the brain revealed a well?defined intraventricular mass lesion in the fourth ventricle and foramen of Luschka. She underwent craniotomy and gross total excision of the lesion. Histopathological and immunohistochemical findings confirmed the diagnosis of atypical choroid plexus papilloma (WHO Grade II). We discuss the various treatment options for this condition and review the relevant literature.

A study on childhood microbial keratitis in South India

Purpose: The aim of this study was to determine the predisposing risk factors, clinical characteristics, microbiological profile, and visual and functional treatment outcome of microbial keratitis including viral keratitis in children. Methods: A prospective study was carried out in a tertiary care institute over a period of 18 months on 73 pediatric patients. Data collected was analyzed for demographics of the patient population, causative organisms, and management outcome in terms of visual and functional outcome. Results: Patients in the age group from 1 month to 16 years were included, with a mean age of 10.81 years. Trauma was the commonest risk factor (40.9%), with unidentified foreign body fall being the most common (32.3%). No predisposing factors were identified in 50% of cases. Also, 36.8% of eyes were culture positive, with bacterial isolates in 17.9% and fungus in 82.1%. Moreover, 7.1% eyes were culture positive for Streptococcus pneumoniae and Pseudomonas aeruginosa each. Fusarium species (67.8%) was the commonest fungal pathogen, followed by Aspergillus species (10.7%). Also, 11.8% were clinically diagnosed as viral keratitis. No growth was found in 63.2% of patients. Treatment with broad?spectrum antibiotics/antifungals was administered in all cases. At the final follow?up, 87.8% achieved a best corrected visual acuity (BCVA) of 6/12 or better. Therapeutic penetrating keratoplasty (TPK) was required by 2.6% of eyes. Conclusion: Trauma was the major cause for pediatric keratitis. Majority of the eyes responded well to medical treatment, with only two eyes needing TPK. Early diagnosis and prompt management helped majority of the eyes to achieve a good visual acuity after the resolution of keratitis.

Eye banking and keratoplasty trend analysis during the COVID-19 pandemic: A South Indian observational study

Purpose: To analyze the impact on eye donation and corneal transplantation during the COVID?19 pandemic in a tertiary eye hospital in south India. Methods: A retrospective analysis of the donor and recipient records during the study period from January 2020 to May 2021 was conducted and tabulated in Microsoft Excel 2013. Demographic details of the donor, utility rate, cause of death, culture characteristics, storage methods, wet lab usage, and the surgical donor outcomes were evaluated. Additionally, the postoperative workup of the recipients, diagnosis, graft infection and rejection episodes, development of COVID?19 postoperatively, and outcome in terms of visual acuity at one, three, and six months were also noted. Results: A total of 466 eyes from 249 donors were received during the study period. The mean age of the donor population was 62.43 years (20.9). The corneal transplantation utility rate was 36.4% (n = 170). Fifty?one percent of the total transplant surgeries were for therapeutic purposes. This was followed by penetrating optical keratoplasty (34%), Descemet’s stripping endothelial keratoplasty (9%), and patch grafts (3%). Seventeen (10%) graft rejection episodes were noted and nine (53%) had complete resolution after medical treatment. Conclusion: Proper preventive measures are key to carrying out safe and efficient eye banking activities even during a deadly pandemic, as COVID?19 transmission via transplantation is rare.

A Tinnitus Inventory Focusing on Body Function, Activities, and Participation Using the International Classification of Functioning, Disability and Health

Background and Objectives@#This study describes the development of an International Classification for Functioning, Disability and Health (ICF)-based inventory for tinnitus (ICF-TINI) that measures the impact of tinnitus on the function, activities, and participation of an individual. @*Subjects and Methods@#This cross-sectional study utilized the ICF-TINI, which included 15 items from the two ICF components of body function and activities. We included 137 respondents with chronic tinnitus. Confirmatory factor analysis validated the two-structure framework (body function, activities and participation). The model fit was assessed by comparing fit values of chi-square (df), root mean square error of approximation, comparative fit index, incremental fit index, and Tucker-Lewis index, with the suggested fit criteria values. Cronbach’s alpha was used to assess internal consistency reliability. @*Results@#The fit indices confirmed the presence of two structures in ICF-TINI, while the factor loading values suggested each item’s goodness of fit. The ICF-internal TINI exhibited high consistency reliability (0.93). @*Conclusions@#The ICFTINI is a reliable and valid tool for assessing the impact of tinnitus on an individual’s body function, activities, and participation.

Granular cell ameloblastoma: A rare and unique variant

Ameloblastoma is a slow-growing and locally invasive epithelial odontogenic tumor of the jaw that runs a benign course in most cases. Granular cell ameloblastoma is a rare subtype of ameloblastoma, showing the granular transformation of its cytoplasm. It is considered as an aggressive variant of ameloblastoma. Herein, we report the case of a 34-year-old male patient who presented with a swelling in the left cheek for a 1-year duration with a recent rapid increase in size. Examination showed a 4 � 3 cm growth involving the left buccal mucosa and retromolar area. Imaging studies showed expansile lytic lesion mandible. Biopsy revealed neoplasm with odontogenic epithelial islands showing peripheral palisading of tall columnar cells with reversal of polarity and the center of the islands showing stellate reticulum-like cells which were markedly replaced by granular cells. Granular cells can appear in various odontogenic and non-odontogenic tumors. When there is extensive granular cell change in ameloblastoma, it should be differentiated from other oral lesions with granular cells including granular cell odontogenic tumor, granular cell tumor, and congenital epulis.

Side port incision in manual small-incision cataract surgery � A teaching video for postgraduates

Background: Manual Small Incision Cataract Surgery (MSICS) is the basic of cataract surgery with a short learning curve, less time- consuming, and can be performed in high-volume setups at low cost. Hence, it is imperative for every surgeon to know in detail the perfect way of wound construction and nucleus delivery methods. Purpose: A teaching video prepared for the postgraduates to understand the importance of creating a proper side port wound construction in MSICS. Synopsis: In MSICS, the side port is made for the intraocular manipulation, to fill the anterior chamber (AC) with viscoelastic and Balanced salt solutions, for easier rhexis in fluid tight maintained AC, for easy aspiration of cortex with deep AC, for cutting the extended rhexis margin with the vannas and for dialling the IOL into the bag complex (Video clip 1). In this video, a limbal stab incision for the side port is created with the 15 degree side port blade made of polycarbonate handle with maximum width of a 20G needle (1.5mm) made parallel to the iris plane of 1.5mm and the 90-110 degree distance from the superior main scleral incision to avoid astigmatic change in axis and power (Video clip 2). It is constructed with the pushing force applied along the cutting edge of the blade through the cornea to create an internal and external ostium, 0.5mm to 1mm thickness into the corneal stroma. The incision produced this way is considered astigmatically neutral (Video clip 3&4). Apart from the astigmatism, the side port is very important to avoid intra and postoperative wound leakage, iris prolapse, and DM detachment. The wound leakage favours bacterial contamination and endophthalmitis (Video clip 5). Ensure good quality of blade while entering the AC (Video clip 6). Hence, albeit small, the side port incision is as important as the main incision. Highlights: The video explains the importance of creating a proper sideport, the benefits and the complications involved were clearly explained.

Preferred practice of cataract surgery in brown cataract: A questionnaire-based survey among Indian ophthalmic surgeons

Purpose: To determine the most preferred method of operating brown cataracts among ophthalmologists in India. Methods: A cross?sectional, questionnaire?based study was conducted among ophthalmologists all over India through electronic and social media from May 1 to June 15, 2022. All single, voluntary entries within the stipulated time period were accepted for analysis. Results: A total of 230 ophthalmologists participated in the study among which 198 (86%) preferred Manual small-incision cataract surgery (mSICS) as the first option. This was preferred due to the high risk of complications associated (40, 33.6%) as well as endothelial damage due to increased Phaco power (53, 47.9%). The majority of the surgeons (162, 70.4%) preferred a superior tunnel for SICS, and 51.7% (119) performed continuous curvilinear capsulorhexis in 100% of their cases. The most common complication encountered was posterior capsular rupture (PCR) (66%), followed by zonular dialysis (ZD) (18.7%), whole bag removal (8.3%), and Descemet抯 membrane detachment (7%). Conclusion: Despite diverse recent new modalities of Femto Laser assisted cataract surgery (FLACS). Phakonit, and Smart Intraocular Lens (IOLs), the majority of ophthalmologists still find the manual small-incision cataract surgery (mSICS) procedure a safe surgery for mature brown cataracts.

Comparison of gingival inflammatory parameters and pain perception on periodontal probing - a cross sectional study, part II / Comparación de parámetros inflamatorios gingivales y percepción del dolor en el sondaje periodontal - un estudio transversal, parte II

Background: Probing of the periodontal pocket is an essential part of the diagnosis of periodontal disease and 15-77% of untreated periodontal patients experience pain during probing. Therefore, the objective of this study is to evaluate the pain perceived by patients with dental plaque-induced gingivitis and chronic periodontitis during periodontal probing and the main objective includes the evaluation of the relationship between pain perceived during periodontal probing and gingival inflammatory parameters. Material and Methods: A total of 475 participants were recruited into the study. The patients were divided into two groups: Group-A (Gingivitis Group - 275 patients) and Group-B (Chronic Periodontitis Group - 200 patients). Clinical parameters included analysis of bleeding on probing, simplified gingival index, pocket depth on probing, and clinical attachment level. Pain score was recorded using the HP VAS scale and all patients participated in the study after a detailed explanation of the study protocol. Results: A significant difference in pain perception was noted between groups, highlighting the role of the degree of inflammation in the examination of periodontal parameters. Conclusion: Within the limitations of the present study, we can conclude that pain perception is directly correlated with the degree of inflammation in periodontitis rather than plaque-induced gingivitis during periodontal probing. Therefore, some form of adjuvant topical anesthesia may be considered in order to reduce pain levels in severely inflamed patients, to encourage continued acceptance of supportive periodontal therapy.

Antecedentes: El sondaje de la bolsa periodontal es una parte esencial en el diagnóstico de la enfermedad periodontal. 15-77% de los pacientes periodontales no tratados experimentan dolor durante el sondaje. Por lo tanto, el objetivo de este estudio es evaluar el dolor percibido por pacientes con gingivitis inducida por placa dental y periodontitis crónica durante el sondaje periodontal y el objetivo principal incluye la evaluación de la relación entre el dolor percibido durante el sondaje periodontal con parámetros inflamatorios gingivales. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron en 2 grupos: Grupo - A (Grupo de gingivitis - 275 pacientes) y Grupo - B (Grupo de periodontitis crónica - 200 pacientes). Los parámetros clínicos incluyeron el análisis del sangrado al sondaje, el índice gingival simplificado, la profundidad de la bolsa al sondaje y el nivel de inserción clínica. La puntuación del dolor se registró utilizando la escala HP VAS y todos los pacientes participaron en el estudio después de una explicación detallada del protocolo del estudio. Resultados: Se notó una diferencia significativa en la percepción del dolor en el grupo B que en el grupo A, lo que significa el papel del grado de inflamación en el examen de los parámetros periodontales. Conclusión: Dentro de las limitaciones del presente estudio, podemos concluir que la percepción del dolor se correlaciona directamente con el grado de inflamación que se observa en la periodontitis más que con la gingivitis inducida por la placa dental durante el sondaje periodontal. Por lo tanto, se puede considerar alguna forma de anestesia tópica adyuvante para reducir los niveles de dolor en pacientes gravemente inflamados para fomentar la aceptación continua de la terapia periodontal de apoyo.

Association of Serum 8-isoprostaglandin F2? Levels with Glycemic Control in Type 2 Diabetes Patients with Senile Cataract

Background : Lipid Peroxidation (LPO) plays a major initiative factor of cataractogenesis in both age-related or senile cataract and Diabetic cataract. Recently, 8-isoprostaglandin F2? (8-iso-PGF2?) is a reliable biomarker of in-vivo LPO and used as potential indicator of oxidative stress. However, serum 8-iso-PGF2? concentration and its association with glycemic control (HbA1c) in the pathogenesis of diabetic cataract subjects are still unknown. Objectives : The present study was designed to estimate 8-iso-PGF2? and antioxidant enzymes levels in serum of Type 2 Diabetes Mellitus patients with senile cataract compared to healthy individuals without cataract as control. To assess the magnitude of the association between 8-iso-PGF2? and glycemic status in diabetic cataract. Materials and Methods : 60 Diabetic Senile Cataracts (DSC) and 60 healthy individuals without cataract in the age group between 45-75 years of both genders. 8-iso-PGF2?, Superoxide Dismutase [Cu-Zn] (SOD3) and Catalase (CAT) concentration were estimated in serum by ELISA method. Results : The mean concentration of 8-iso-PGF2? was significantly increased (541.6±142.7 pg/ml, p<0.001) and mean concentration of SOD3 (102.1±32.8 ng/ml, p=0.007) and Catalase (1005±274.5 IU/ml, p<0.001) were significantly decreased in serum of diabetic senile cataract when compared to healthy individuals without cataract (control). A negative correlation between serum 8-iso-PGF2? and SOD3 and positive correlation between serum 8- iso-PGF2? and fasting blood glucose were observed in Diabetic Senile Cataracts. Conclusion : The present findings indicate that increased 8-iso-PGF2? is associated with oxidative stress which plays a significant role in the pathogenesis of cataract in diabetic patients

Gore-tex a magic sheet for symblepharon prevention!

Background: Symblepharon occurs as chronic sequelae of severe chemical injuries. The risk of recurrence is high due to unpredictable wound healing of conjunctiva and tenons following excision in young patients. Gore-tex aids in prevention of the recurrence of pterygium 1. Purpose: To present a surgical video on role of Gore-tex in grade 4 Symblepharon lysis. Synopsis: A 28-year-old male with a previous history of Grade 4 chemical injury presented with symblepharon and total obliteration of both upper and lower fornices after one year in the right eye. He underwent symblepharon lysis, Living related conjunctival allograft, Amniotic membrane graft and Gore-tex. The video explains the surgical steps in detail. A 360-degree complete peritomy was done, Symblepharon was released from the corneal surface, and the fibrotic tissue was extensively dissected away from the corneal surface and released into the fornix. Further, cryopreserved AMG was placed over the entire raw ocular surface and sutured to the episclera with glue. Prepared Gore- tex was placed on the superior and inferior fornix and sutured with 10-0 nylon suture. Again, AMG was placed over the Gore-tex in the fornices and covered with glue. A small 2x2mm biopsy of limbal stem cells from the superior limbus was already excised from the fellow eye (CLAG) and then Lr-CLAL was prepared from the patient’s mother. These two grafts were placed on the nasal and temporal bulbar surface over the AMG and sutured to the underlying AMG and the episclera with glue. The entire surface was then covered with the AMG to promote epithelisation. At one month postoperative period, patient had stable ocular surface with intact Limbal conjunctival graft with mild conjunctival recurrence of fibrosis superiorly. Highlights: The video clearly explains the surgical steps of Symblepharon and the benefits of using Gore-tex.

Analysis of hesitancy and motivational factors for COVID-19 vaccination among patients presenting to eye care hospitals – A multicenter questionnaire-based survey

Purpose: To analyze the hesitancy and motivational factors related to coronavirus disease 2019 (COVID?19) vaccination among patients visiting for eye care. Methods: A telephonic survey was conducted using validated questionnaires consisting of 36 questions in five sections from July 1 to July 31, 2021. Patients visiting six tertiary centers and one secondary center of our eye hospitals were interviewed over their phones, and their responses were entered onto the Google forms. The responses were recorded as demographics, health status, awareness about vaccination, factors contributing to hesitancy or acceptance to vaccinate, and general perception about the vaccine. Results: A total of 5033 patients were surveyed. The mean age was 49.0 ± 14.2 years. A total of 563 (11.2%) patients gave a history of symptoms or were tested positive for COVID?19; 2225 (44.2%) patients were already COVID?19 vaccinated. Around 2883 (56%) patients were aware of getting infection despite vaccination, and 4092 (81.3%) perceived vaccination should be compulsory. The main reason for vaccination hesitancy was the fear of side effects (n = 487, 17.3%). The fear of getting infected was the most common reason for vaccination (n = 911, 40.9%). Factors associated with a lower proportion of vaccinated individuals included younger age (P < 0.001), female gender (P < 0.001), lower education (P < 0.001), lower income (P < 0.001), and rural residence (P = 0.33). Conclusion: Creating awareness about the minor side effects and reassurance can allay an individual’s fears. The fear associated with the rapid spread of infection and associated mortality needs to be utilized to increase vaccination acceptance. A targeted approach toward groups with poor uptake of vaccination is necessary.

A safer alternative approach to penetrating keratoplasty in opaque corneas

Background: This video demonstrates a useful technique of keratoplasty which can be routinely undertaken by all surgeons when imaging modalities such as anterior segment optical coherence tomography are not available and prior patient history is not forthcoming. Purpose: To demonstrate a technique of lamellar separation and layer by layer removal of host cornea when dealing with keratoplasty in perforated corneal ulcers, adherent leucomas, dense corneal opacities, which obscure visualization of the iris and anterior chamber details. Synopsis: In this video, we demonstrate penetrating keratoplasty in a failed opacified graft with iridocorneal adhesions, with no visualization of anterior chamber details. Lamellar dissection of the host cornea is done starting at its periphery and moving centrally, with gentle peeling of the superficial layers, the epithelium and bulk of stroma, following which, the deeper portion of the cornea is dissected and separated from underlying adherent iris tissue. Layer by layer separation allows better visualization through the remaining thin layers of the cornea. This permits fine dissection and layered removal of the cornea, thereby avoiding injury to iris and lens. Debulking of the host cornea decreases the force that is needed to be applied to separate adherent iris tissue from the host cornea, and reduces the chances of sudden entry into the anterior chamber and subsequent damage to the iris or lens. This also reduces the chance of iris tears, iridodialysis and bleeding from the iris and helps maintain iris integrity, which is essential intraoperatively for protection of lens and anterior chamber formation, and to avoid glare and photophobia postoperatively. Preventing iris damage also reduces the chances of formation of peripheral anterior synechiae (PAS), which can predispose to graft rejection, graft failure and secondary glaucoma. Highlights: Layer by layer corneal separation beginning inside the graft host junction, careful separation of iridocorneal adhesions and PAS is a helpful technique to optimally preserve the anterior segment anatomy during difficult cases of penetrating keratoplasty.

Evaluation of pain perception on periodontal probing in patients with dental plaque induced gingivitis and chronic periodontitis - a cross sectional study, part I / Evaluación de la percepción del dolor al sondaje periodontal en pacientes con gingivitis inducida por placa dental y periodontitis crónica: un estudio transversal, parte I

Background: Probing of periodontal pockets is an essential part in the diagnosis of periodontal disease. Fifteen to seventy seven percent of untreated periodontal patients experience pain during probing. Hence the aim of this study is to evaluate the pain perceived by patients with gingivitis and periodontitis during periodontal probing. The goals of this study were to compare the patients' pain perception when using a conventional UNC15 probe and a manual pressure sensitive periodontal probe, and to relate the clinical features of gingivitis and periodontitis to the discomfort associated with periodontal probing. Material and Methods: A total of 475 subjects were recruited into the study. The subjects were initially divided into two groups ­ Group ­ A (Gingivitis group - 275 patients) and Group ­ B (Chronic Periodontitis group -200 patients) according to the AAP 1999 Classification. These two groups were further subdivided into two groups each (Gingivitis ­ Conventional Probe ­ GCP, Gingivitis ­ Manual Pressure Sensitive Probe ­ GMPS, Periodontitis - Conventional Probe ­ PCP, Periodontitis ­ Manual Pressure Sensitive Probe ­ PMPS) using a computer generated program of random numbers. Results: A significant difference was noted in pain perception when pressure sensitive probe was used compared to conventional UNC-15 probe. Reduced Bleeding on Probing and Pain scores were noted in Chronic periodontitis subjects with use of pressure sensitive probe, which was statistically significant (p<0.001). Conclusion: Dentistry has changed its focus towards painless dentistry. In this context, the present study presents data towards use of manual pressure sensitive probes, which offers an advantage of low cost when compared to more advanced computerized systems with reduced pain during periodontal examination. It could result in a positive attitude of the patients towards continuous supportive periodontal therapy thereby monitoring periodontal health.

Antecedentes: El sondaje de los sacos periodontales es una parte esencial en el diagnóstico de la enfermedad periodontal. Del quince al setenta y siete por ciento de los pacientes periodontales no tratados experimentan dolor durante el sondaje. De ahí que el objetivo de este estudio fué evaluar el dolor percibido por pacientes con gingivitis y periodontitis durante el sondaje periodontal. Los objetivos de este estudio fueron comparar la percepción del dolor de los pacientes al usar una sonda UNC15 convencional y una sonda periodontal sensible a la presión manual, y relacionar las características clínicas de la gingivitis y la periodontitis con la incomodidad asociada con el sondaje periodontal. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron inicialmente en dos grupos - Grupo - A (grupo de Gingivitis - 275 pacientes) y Grupo - B (grupo de Periodontitis Crónica - 200 pacientes) de acuerdo con la Clasificación AAP 1999. Estos dos grupos se subdividieron en dos grupos cada uno (Gingivitis - Sonda convencional - GCP, Gingivitis - Sonda manual sensible a la presión - GMPS, Periodontitis - Sonda convencional - PCP, Periodontitis - Sonda manual sensible a la presión - PMPS) usando un programa generado por computadora de datos aleatorios. números. Resultados: Se notó una diferencia significativa en la percepción del dolor cuando se usó una sonda sensible a la presión en comparación con la sonda UNC-15 convencional (p<0,001). Conclusion: La odontología ha cambiado su enfoque hacia una odontología sin dolor. En este contexto, el presente estudio presenta datos hacia el uso de sondas manuales sensibles a la presión, que ofrece una ventaja de bajo costo en comparación con sistemas computarizados más avanzados con reducción del dolor durante el examen periodontal. Podría resultar en una actitud positiva de los pacientes hacia la terapia periodontal de apoyo continuo, monitoreando así la salud periodontal.
