The Relationship of Palato‐Gingival Grooves to Localized Periodontal Disease

Abstract

The purpose of this investigation was to determine the prevalence of the palato-gingival groove in maxillary incisor teeth and the health status of the lingual periodontal tissues adjacent to maxillary incisor teeth with and without the grooves. A total of 531 individuals aged 17 to 35 years were examined for the presence or absence of palato-gingival grooves in their maxillary incisor teeth. A Plaque Index (PII), Gingival Index (GI), and Periodontal Disease Index (PDI) were recorded for the lingual aspect of the four maxillary incisors. Tooth mobility was also recorded. The prevalence of the palato-gingival grooves in the 531 individuals examined was 8.5%. Of the 2,099 maxillary incisor teeth examined, 2.33% had a palato-gingival groove. Most of the palato-gingival grooves (93.8%) were in maxillary lateral incisor teeth. Statistical analyses revealed no differences in groove prevalence on the basis of sex or race. Results of the study also indicate that the palato-gingival groove is associated with poorer periodontal health as measured by the GI and PDI and more plaque accumulation as measured with the PII.

Radiographic Alveolar Bone Loss in Patients Undergoing Periodontal Maintenance

“…Anatomically, the upper arch incisors usually present the palatal gingival groove (lateral: 4.40% and central: 0.28%) 54) , which is considered to be a risk area for periodontal disease 15) , since the groove may provide a niche for plaque and bacteria difficult to access during scaling. Therefore, the probability of early tooth loss is higher in the upper arch than in the lower arch incisors 17) .…”

The palato-gingival groove - anatomical anomaly occurred in maxillary lateral incisors: case reports

“…Not all grooved teeth will present a breakdown of the epithelial attachment, but the presence of the anomaly constitutes a risk factor of which the dentist should be aware. Whithers et al 11) reported that the palato-gingival groove is associated with a "poor periodontal health." Unfortunately, the "poor periodontal health"combined with a deep groove may put the tooth at risk, with poor prognosis 12) , despite periodontal and endodontic treatment [13][14][15] .…”

Integration of PRF and Biodentine in Palatogingival Groove case

“…The usage of this trait in anthropologic studies indicates its racial link [6]. The incidence of radicular groove is reported to be between 2.8% and 18% [7][8][9][10].…”
