  • Periodontal Re-Treatment in Patients on Maintenance Following Pocket Reduction Surgery Roberto Galindo1, Paul Levi2, Andres Pascual Larocca1, José Nart1
    Periodontal Re-treatment in Patients on Maintenance Following Pocket Reduction Surgery Roberto Galindo1, Paul Levi2, Andres Pascual LaRocca1, José Nart1 1Periodontics Department, Universitat Internacional de Catalunya, Spain. 2Periodontics Department, School of Dental Medicine, Associate Clinical Professor at Tufts University, USA. Abstract When pocket elimination has been done and periodontal stability has been achieved, patients are advised to be on Maintenance Therapy (MT), also known as Supportive Periodontal Care (SPC). The compliance rate for patients on MT is low, and efforts to optimize acquiescence are only partly successful. The question of re-treatment of periodontal diseases is rarely addressed in the literature, and it warrants further clinical research. Aim: To quantify the extent of additional periodontal treatment needed for patients who had previous pocket reduction periodontal surgery and have been on SPC for a minimum period of 12 months. Methods: Patients in this study had received periodontal treatment, which included pocket reduction osseous surgery with an apically positioned flap. The periodontal residents at Universitat Internacional de Catalunya performed the surgeries. After active periodontal therapy, patients were placed on SPC. Erratic patients are defined when they attended less than 75% of their scheduled maintenance appointments within 1 year. Re-treatment is judged necessary when deep pockets (≥ 5mm) are identified, presenting with bleeding on probing. For this study, patients were recalled randomly for a re-evaluation of periodontal conditions. Clinical periodontal parameters are recorded and each patient fills a questionnaire evaluating SPC perception. Results: 64% of patients showed recurrence of periodontal disease. Smokers who were erratic with SPC showed a 100% recurrence rate.

Inadequate tooth structure above the gum line to accommodate a filling, crown, or other restoration, or current restoration set too deep into the gum. To remove excess gum tissue and/or bone. Brief description of the treatment/procedure: PERIODONTAL BONE REGENERATIVE SURGERY This procedure involves regenerating lost bone and gum tissue due to gum disease. Your teeth are kept in place by your jaw bone and gum tissue. When you have gum disease, bacteria causes a pocket to form around your teeth and gums. When this happens, you may get infection and/or your teeth may become loose. You will be given an injection of local anesthesia. With local anesthesia, an injection of drugs causes numbness in the exact location of a minor surgery or dental procedure. Your dentist will make an incision (cut) in your gum to expose the eroded bone and tooth roots. The area will be cleaned to get rid of calculus (tartar), infected gum tissue, and bacteria. Graft material will be placed in the areas of bone loss around the teeth. Different types of graft material may be used: Allograft.

    Plain Facts about Periodontal Disease bcbsfepdental.com Learn what it might mean to have swollen gum and what can be done about it. What is Periodontitis? Periodontitis (per-e-o-don-TIE-tis), also called Gum Disease, is defined as a serious gum infection that damages the gum tissue and can, over time, destroy the bone that supports your teeth. Healthy gums are generally firm, pale pink, and wrap closely around teeth. Symptoms of periodontitis can include: • Swollen gums • Bright red to purplish gum tissue • Tender gums • Blood when flossing or brushing Prevention of Periodontal Disease • Bad breath The easiest way to prevent periodontitis is to practice good oral hygiene – • Pus between teeth and gums brushing twice daily, for two minutes, • Painful chewing using a soft bristled brush and flossing daily. • Gums pulling away from teeth Regular dental visits with cleanings are • New spaces between teeth also necessary to maintain a healthy • Loose teeth mouth. Cleanings should generally occur every six to 12 months, however, if • Loss of tooth/teeth you are at a higher risk for periodontal • Changes to how your teeth fit together when you disease (see Risk Factors), your dentist bite What Causes Periodontitis? According to the Centers for Disease Control and Prevention, 46% of Americans age 30 and over show signs of periodontal disease. Periodontitis is common, but usually preventable. It starts with plaque – the sticky film you find on your teeth each day, composed of food particles, saliva, and bacteria. If you don’t remove all of the plaque from around your gum line when you brush or floss, that plaque will eventually harden into tartar (calculus).

    Dental Policy Subject: Periodontal Maintenance Guideline #: 04-901 Publish Date: 03/15/2018 Status: Revised Last Review Date: 02/05/2018 Description This document addresses periodontal maintenance. Note: Please refer to the following documents for additional information concerning related topics: Prophylaxis: 01-101 Scaling and Root Planing: 04-301 Gingivectomy or Gingivoplasty: 04-202, Mucogingival Surgery and Soft Tissue: 04-204 Osseous Surgery: 04-205 Clinical Indications Periodontal maintenance is a nonsurgical treatment considered appropriate, following periodontal therapy, that continues for the life of the dentition or any implant replacements and provides treatment and continuing care of patients with a history of/and ongoing periodontal disease. Periodontal maintenance is considered therapeutic, rather than prophylactic, and constitutes continuing treatment for patients with a diagnosis of periodontal disease. The therapeutic objective of Periodontal Maintenance is to reduce or eliminate causative factors responsible for initiating host inflammatory responses. The desired outcome should result in maintenance of the periodontal health status attained as a result of active periodontal therapy. Periodontal Maintenance is: 1. A demanding and time-consuming procedure involving instrumentation of the tooth crown and root structures. 2. A procedure to remove etiological factors such as plaque and biofilm, adherent calculus deposits, and diseased cementum (root structure) that may be permeated with calculus, microorganisms and microbial

(University of Mumbai). ABSTRACT The study was aimed to formulate and evaluate dental gel containing clove oil as the chief constituent for the treatment of periodontitis. Clove oil has a wide spectrum of antibacterial activity against a number of periodontal pathogens, hence it is selected for the treatment of periodontitis. Clove oil gel is formulated by using carbopol 934 as gelling agent, clove oil as medicinal agent, polyethylene glycol as co-solvent, methyl paraben and propyl paraben as preservative and required quantity of distilled water as vehicle. The periodontal disease commonly refers to inflammatory diseases that are plaque induced i.e. gingivitis and periodontitis. Gingivitis, the moderate stage of disease caused by an accumulation of supragingival plaque and characterized by swelling, light bleeding and redness of the marginal gingival. Gingivitis is associated with a change in the microflora, shifting from a Gram-positive anaerobic flora to a more Gram negative one.

Dentin hypersensitivity (DH) is characterized by short sharp pain arising from exposed dentin in response to stimuli. The most widely accepted theory of how the pain occurs is Brannstrom’s hydrodynamic theory, fluid movement within the dentinal tubules. The condition generally involves the facial surfaces of teeth near the cervical aspect and is very common in premolars and canines. This condition is frequently encountered by dentists, periodontists, hygienists and dental therapists. Some dental professionals lack confidence in treating DH. The management of this condition requires a good understanding of the complexity of the problem, as well as the variety of treatments available. This review considers the etiopathogenesis, incidence, diagnosis, prevention and management of dentinal hypersensitivity. DH is diagnosed after elimination of other possible causes of the pain.

The explanations were included to give you a clear understanding of why each choice was selected. Should you encounter any doubts or problems in your interpretation of the explanation, it is your responsibility to consult your textbook, journal articles or handouts for further clarification. I will also be available to assist you if needed. I hope that the explanations below will not only help you to understand each question better but will help to broaden your knowledge in Periodontics as you prepare for the examination. Good Luck! 1. When would you prescribe an antibiotic in conjunction with periodontal scaling and root planing? a. Severe gingivitis b. Localized aggressive periodontitis* c. Advanced Chronic periodontitis d. Linear gingival erythema Antibiotic therapy is not generally recommended for patients with a diagnosis of chronic periodontitis, unless there are some unique systemic problems or compromised conditions. Patients with chronic periodontitis and severe gingival inflammation usually respond well to elimination of the local factors (nonsurgically and/or surgically) and compliance with oral hygiene and supportive periodontal care. Patients with the more aggressive forms of periodontitis (Localized Aggressive Periodontitis and Generalized Aggressive Periodontitis) are generally treated with antibiotics. There is usually a specific microbe that is associated with the disease process, which may have the potential to invade the host’s connective tissues. The microbe, Actinobacillus actinomycetemcomitans, is associated with LAP.
