Act as a postgraduate Periodontology professor and university examiner. Prepare comprehensive point-wise theory examination notes for the following Question:- Classify osseous defects & differentiate between suprabony and infrabony pockets. Instructions: Use ONLY the uploaded references/documents. Do not use outside knowledge. Extract and synthesize information from all relevant uploaded references and integrate them into a single answer. Include: Tables wherever possible, Flowcharts in text format, Important examiner keywords highlighted in bold, Recent terminology changes. After every major point, mention the reference/source document name from which the information was derived. Do not omit any information available in the uploaded references regarding Classify osseous defects & differentiate between suprabony and infrabony pockets. If different references provide different viewpoints, compare them in a separate table. Do NOT simplify, reinterpret, modernize, paraphrase or replace textbook terminology with AI-generated wording. Accuracy to source is more important than completeness. If a point is not present in the uploaded reference or cited textbook section, do not generate it from general knowledge.
You are a research assistant. Read the following uploaded textbook files and extract ALL content related to: (1) Classification of osseous defects, (2) Suprabony pockets, (3) Infrabony/intrabony pockets, (4) Differences between suprabony and infrabony pockets, (5) Types of bony defects (craters, furcation, hemiseptum, etc.). Read these files using read_file tool, using pagination (offset/limit=200 at a time) as needed. Extract verbatim text relevant to the topic. Do NOT paraphrase. Quote exact textbook language. Files to read: 1. /home/daytona/workspace/attachments/3ff028d7-b005-40d5-82f7-ae3160655633/14 th ed Newman_and_Carranza's_Clinical_Periodontology_and_Implantology, - Copy.txt 2. /home/daytona/workspace/attachments/3ff028d7-b005-40d5-82f7-ae3160655633/Carranza's Clinical Periodontology, 10th Edition - Copy.txt 3. /home/daytona/workspace/attachments/3ff028d7-b005-40d5-82f7-ae3160655633/Clinical Periodontology and Implant Dentistry 6th Edition - Copy.txt 4. /home/daytona/workspace/attachments/3ff028d7-b005-40d5-82f7-ae3160655633/Periodontics Medicine Surgery Implants.txt 5. /home/daytona/workspace/attachments/3ff028d7-b005-40d5-82f7-ae3160655633/Periodontology for The Dental Hygienist .txt Search strategy: Use grep tool first with patterns like "osseous defect", "suprabony", "infrabony", "intrabony", "bony defect", "crater", "furcation", "hemiseptum", "one-wall", "two-wall", "three-wall", "angular defect", "horizontal bone loss" to find the relevant line numbers in each file. Then use read_file with appropriate offset/limit to extract those sections. Return the COMPLETE verbatim extracted text from each file, clearly labeled by source. Include all tables, classifications, and comparison text found.
