DEVELOPMENTAL OR ACQUIRED DEFORMITIES AND CONDITIONS (Box 4)
DEVELOPMENTAL OR ACQUIRED DEFORMITIES AND CONDITIONS 1. Localized Tooth-Related Factors That Modify or Predispose to Plaque-Induced Gingival Diseases or Periodontitis 1. Tooth anatomic factors 2. Dental restorations or appliances 3. Root fractures 4. Cervical root resorption and cemental tears
Anatomic factors These factors are associated with malformations of tooth development or tooth location. cervical enamel projections found on 15% to 24% of mandibular molars and 9% to 25% of maxillary molar enamel pearls Palatogingival grooves Proximal root grooves found primarily on maxillary incisors, are observed in 8. 5% of individuals on incisors and maxillary premolars predispose to plaque accumulation, inflammation, and loss of clinical attachment and bone.
enamel pearls
Palatogingival grooves
Proximal root grooves
Tooth location Tooth malalignment open contacts food impaction. predisposes to plaque accumulation and inflammation in children and may predispose to clinical attachment loss and loss of alveolar bone in adults
Mucogingival Deformities and Conditions around Teeth A mucogingival deformity may be defined as "a significant departure from the normal shape of gingiva and alveolar mucosa" and may involve the underlying alveolar bone. Mucogingival defect depicted by recession
Mucogingival surgery "periodontal surgical procedures designed to correct defects in the morphology, position, and/or amount of gingiva". for esthetic reasons to enhance function to facilitate oral hygiene

Mucogingival Deformities and Conditions on Edentulous Ridges require corrective surgery to restore form and function before the prosthetic replacement of missing teeth or implant placement. Clinical image of edentulous ridge defect.

Occlusal Trauma from occlusion cannot induce periodontal tissue breakdown. Experiments carried out in humans as well as animals, have produced convincing evidence that neither unilateral forces nor jiggling forces, applied to teeth with a healthy periodontium, result in pocket formation or in loss of connective tissue attachment
Trauma from occlusion Resorption of alveolar bone Increased tooth mobility transient physiologic adaptation of the periodontal ligament and surrounding alveolar bone to the traumatizing forces permanent In teeth with progressive, plaque-associated periodontal disease, trauma from occlusion may enhance the rate of progression of the disease (act as a co-factor in the destructive process).
Proper treatment of plaque associated with periodontal disease. Arrest the destruction of the periodontal tissues even if the occlusal trauma persists
